[0082] For a better understanding of the method for scheduling a
terminal device, the network device, and the terminal device
according to the embodiments of the present disclosure, a scenario
that may be applied to the embodiments of the present disclosure is
briefly introduced in the following with reference to FIG. 1.
[0083] FIG. 1 is a schematic diagram of a possible application
scenario of an embodiment of the present disclosure. The
communication system shown in FIG. 1 includes a network device and
a terminal device. The network device may schedule a terminal
device to perform a pre-scheduled service with a scheduling
command. Specifically, the network device may, with the scheduling
command, schedule the terminal device to transmit uplink data to a
base station through a corresponding frequency domain resource at a
certain time moment or time point. Alternatively, the network
device may, with the scheduling command, schedule the terminal
device to receive downlink data from a base station through a
corresponding frequency domain resource at a certain time moment or
time point.
[0084] FIG. 2 is a schematic flowchart of a method for scheduling a
terminal device according to an embodiment of the present
disclosure. The method of FIG. 2 includes the following steps.
[0085] In step 210, the network device determines first
configuration information. The first configuration information
indicates a time domain resource and a frequency domain resource
used by the terminal device to perform a pre-scheduled service.
[0086] The first configuration information may indicate the time
domain resource and the frequency domain resource used by the
terminal device to perform the pre-scheduled service in various
indication manners. Specifically, the first configuration
information may indicate the time and frequency domain resources
used by the terminal device to perform the pre-scheduled service in
at least the following three situations.
[0087] In the first situation, the pre-scheduled service is a
periodic service, and the first configuration information indicates
a transmission period of the pre-scheduled service and a frequency
domain resource used by the terminal device to perform the
pre-scheduled service at each of the time moments. At at least two
of the time moments, the terminal device uses different frequency
domain resources to perform the pre-scheduled service.
[0088] The periodic service may be a service of periodically
transmitting data between the terminal device and the network
device. For example, a smart meter transmits user's power
consumption data to the network device at a fixed time
interval.
[0089] The first configuration information may indicate the
transmission period of the pre-scheduled service and the frequency
domain resource used by the terminal device to perform the
pre-scheduled service at each of the time moments in various
manners. For example, the first configuration information may be
{T, F1, F2, F3, . . . }, where T represents the transmission period
of the pre-scheduled service, and the terminal device performs the
pre-scheduled service at every time T, and F1, F2, F3, . . .
represent the frequency domain resources used by the terminal
device to perform the pre-scheduled service for the first time, the
second time, and the third time . . . , respectively.
[0090] However, the first configuration information is composed of
information of a single period and information of a list. The
period information indicates the transmission period of the
pre-scheduled service is T, and the list information is as shown in
Table 1, in which F1, F2, F3, . . . represent the frequency domain
resources used by the terminal device to perform the pre-scheduled
service at a first time moment, a second time moment, and a third
time moment . . . , respectively. A time interval between the first
time moment and the second time moment is T, and a time interval
between the second time moment and the third time moment is also T.
The first time moment may be a time moment when a preset time
interval has elapsed since the terminal device receives the first
configuration information, the size of the preset time interval may
be determined according to a communication protocol, or the preset
time interval may be negotiated between the terminal device and the
network device. Alternatively, the terminal device does not perform
the pre-scheduled service immediately upon receipt of the first
configuration information, but performs the pre-scheduled service
immediately upon receipt of trigger information from the network
device.
TABLE-US-00001 TABLE 1 F1 F2 F3 F4 . . .
[0091] The above list information may also be as shown in Table 2.
As shown in Table 2, 1, 2 and 3 respectively indicate the first
time moment, the second time moment, and the third time moment when
the terminal device performs the pre-scheduled service. F1, F2, F3,
. . . represent the frequency domain resources used by the terminal
device to perform the pre-scheduled service at the first time
moment, the second time moment, and the third time moment,
respectively.
TABLE-US-00002 TABLE 2 1 F1 2 F2 3 F3 . . . . . .
[0092] In addition, the frequency domain resources for the terminal
device to perform the pre-scheduled service at different time
moments may also be periodic. As shown in Table 3 and Table 4, the
frequency domain resources corresponding to the first time moment
to the third time moment are F1, F2, and F3, respectively. The
frequency domain resources corresponding to the fourth time moment
to the sixth time moment are also F1, F2, and F3, respectively.
That is to say, there are three kinds of frequency domain
resources, and the frequency domain resources used by the terminal
device to perform the pre-scheduled service are cycled once for
every three time moments. By configuring the frequency domain
resources in cycles, the frequency domain resources may be utilized
more effectively, and the utilization of the frequency domain
resources can be improved.
TABLE-US-00003 TABLE 3 F1 F2 F3 F1 F2 F3 . . .
TABLE-US-00004 TABLE 4 1 F1 2 F2 3 F3 5 F1 6 F2 7 F3 . . . . .
.
[0093] In the first situation, when the pre-scheduled service is a
periodic service, the first configuration information only
indicates the period in which the terminal device performs the
pre-scheduled service, and does not have to indicate each time
moment that the terminal device performs the pre-scheduled service.
Therefore, it can save certain signaling overhead for scheduling
the terminal device to perform the pre-scheduled service.
[0094] In the second situation, the pre-scheduled service is a
non-periodic service, and the first configuration information
indicates each time moment for the terminal device to perform the
pre-scheduled service and the frequency domain resource used by the
terminal device to perform the pre-scheduled service at each time
moment. The terminal device uses the same frequency domain resource
to perform the pre-scheduled service at each of the time
moments.
[0095] The first configuration information may include two kinds of
information, of which one kind of information indicates the
frequency domain resource used by the terminal device to perform
the pre-scheduled service, and another kind of information
indicates each time moment for the terminal device to perform the
pre-scheduled service. For example, the first configuration
information includes first information and second information, of
which the first information indicates the terminal device to
perform the pre-scheduled service using the frequency domain
resource F1, and the second information is the list information as
shown in Table 5, and indicates the terminal device to perform the
pre-scheduled service at time moments T1, T2 and T3, respectively,
and the frequency domain resource used by the terminal device to
perform the pre-scheduled service at each of the time moments T1,
T2, and T3 is F1.
TABLE-US-00005 TABLE 5 T1 T2 T3 T4 . . .
[0096] In the third situation, the first configuration information
indicates each time moment for the terminal device to perform the
pre-scheduled service, and a respective frequency domain resource
used by the terminal device to perform the pre-scheduled service at
each time moment.
[0097] In the third situation, the pre-scheduled service may be a
periodic service or a non-periodic service. That is, the first
configuration information indicates each time moment for the
terminal device to perform the pre-scheduled service and a
respective frequency domain resource used by the terminal device to
perform the pre-scheduled service at each time moment, regardless
of whether the pre-scheduled service is a periodic service or not.
In this case, the first configuration information may have a
specific form as shown in Table 6, which indicates that the
frequency domain resources used by the terminal device to perform
the pre-scheduled service at time moments T1, T2, T3 . . . are F1,
F2, and F3 . . . , respectively.
TABLE-US-00006 TABLE 6 T1 F1 T2 F2 T3 F3 . . . . . .
[0098] The first configuration information may also be in a
specific form as shown in Table 7. In Table 7, the frequency domain
resources used by the terminal device to perform the pre-scheduled
service at time moments T1-T3 are F1, F2, and F3, respectively, and
the frequency domain resources used by the terminal device to
perform the pre-scheduled service at time moments T4-T6 are also
F1, F2, and F3 respectively. That is to say, the frequency domain
resources used by the terminal device to perform the pre-scheduled
service are cycled, and the frequency domain resources used by the
terminal device to perform the pre-scheduled service are cycled
once for every three time moments.
TABLE-US-00007 TABLE 7 T1 F1 T2 F2 T3 F3 T4 F1 T5 F2 T6 F3 . . . .
. .
[0099] It should be understood that, in Tables 1 to 7 as shown
above, F1, F2, and F3 may be three different frequency domain
resources. Alternatively, two of F1, F2, and F3 may also be the
frequency domain resource, for example, F1 and F2 are the same
frequency domain resource, or F2 and F3 are the same frequency
domain resource, or F1 and F3 are the same frequency domain
resource.
[0100] It should also be understood that the multiple time moments
mentioned above are multiple time domain resources used by the
terminal device to perform the pre-scheduled service. That is, the
time moment means the time domain resource, and the terminal device
performing the pre-scheduled service at the multiple time moments
on the corresponding frequency domain resources means the terminal
device performing the pre-scheduled service at the multiple time
domain resources and on the corresponding frequency domain
resources.
[0101] In step 220, the network device sends the first
configuration information to the terminal device.
[0102] The pre-scheduled service may be an uplink service in which
the terminal device sends data to the network device, or may be a
downlink service in which the terminal device receives data from
the network device. When the pre-scheduled service is an uplink
service, the terminal device sends service data to the network
device on the time domain resource and the frequency domain
resource indicated by the first configuration information after
receiving scheduling information from the network device. When the
pre-scheduled service is a downlink service, after receiving
scheduling information from the network device, the terminal device
receives service data from the network device on the time domain
resource and the frequency domain resource indicated by the first
configuration information.
[0103] In the embodiments of the present disclosure, first
configuration information is provided for indicating the time
domain resource and the frequency domain resource used by the
terminal device to perform the pre-scheduled service. As compared
with the method of indicating only the transmission period and the
frequency domain for the pre-scheduled service to be performed by
the terminal device in the related art, the present disclosure can
flexibly schedule the terminal device to perform pre-scheduled
service.
[0104] In some embodiments, after the network device sends the
first configuration information to the terminal device, the network
device may further send, to the terminal device, second
configuration information, and the second configuration information
is used for reconfiguring the terminal device to perform the
pre-scheduling service using a second frequency domain resource at
at least one second time moment instead of using a first frequency
domain resource at at least one first time moment.
[0105] By the second configuration information, it is possible to
change the one or more time moments and the corresponding frequency
resource for the terminal device to perform the pre-scheduled
service. By enabling flexible configuration, the flexibility in
scheduling is improved and conflicts with other services can be
avoided.
[0106] For example, the first configuration information indicates
that the terminal device to perform the pre-scheduled service using
a frequency domain resource F1 at a time moment T1, and the second
configuration information reconfigures the terminal device, to
indicate the terminal device to perform the pre-scheduled service
using a frequency domain resource F1' at a time moment T1', instead
of using a frequency domain resource F1 at a time moment T1. Here,
T1 is different from T1', and F1 is the same as F1'; or T1 is the
same as T1', and F1 is different from F1'; or T1 is different from
T1', and F1 is different from F1'. That is, the second
configuration information may only change the time moment when the
terminal device performs the pre-scheduled service, or may only
change the frequency domain resource used by the terminal device to
perform the pre-scheduled service, or change both of the time
moment when the terminal device performs the pre-scheduled service
and the frequency domain resource used by the terminal device to
perform the pre-scheduled service.
[0107] The above example shows a case where the at least one first
time moment and the at least one second time moment each indicates
one time moment, when the at least one first time moment and the at
least one second time moment each include a plurality of time
moments, for example, the at least one first time moment includes
time moments {T1, T2, T3}, and the frequency domain resources
corresponding to the time moments {T1, T2, T3} are {F1, F2, F3},
respectively, and the at least one second time moments include time
moments {T1', T2', T3'}, and the frequency domain resources
corresponding to the time moments {T1', T2', T3'} are {Fr, F2',
F3'}, respectively, then in this case, one or more of the time
moments {T1, T2, T3} may be the same as one or more of the time
moments {T1', T2', T3'}, or the time moments {T1, T2, T3} are
totally different from the time moments {T1', T2', T3'}. Similarly,
one or more of {F1, F2, F3} may be the same as one or more of {F1',
F2', F3'}, or {F1, F2, F3} is totally different from {F1', F2',
F3'}.
[0108] When the network device in the related art uses a
semi-static scheduling mode to schedule the terminal device to
perform the pre-scheduled service, the configuration information
sent to the terminal device indicates the period in which the
terminal device performs the pre-scheduled service and the
frequency domain resource used to perform the pre-scheduled
service. For example, the network device sends first scheduling
information to the terminal device, where the first scheduling
information indicates that the terminal device transmits the uplink
data for a period of 100 ms, and the frequency domain resource used
for transmitting the uplink data is the first frequency domain
resource. Then, the terminal device transmits uplink data to the
network device at a transmission period of 100 ms starting from a
certain time moment after the terminal device receives the first
scheduling information, and the certain time moment may be the time
moment upon receipt of the first scheduling information, or may be
a time moment after a time interval has elapsed since the terminal
device receives the first scheduling information.
[0109] When it is needed to change the time moment and the
frequency domain resource for the terminal device to perform the
pre-scheduled service, the network device may send new
configuration information to the terminal device. However, after
receiving the new configuration information, starting from the time
point when the configuration changes, all the configuration has
been changed; however, in fact, it may not be necessary to change
all the time moments, but only need to change some of the specified
time moments. Therefore, the semi-static scheduling mode in the
related art is rather inflexible.
[0110] Such indication manner does not directly indicate which
frequency domain resource is used by the terminal device to
transmit the uplink data to the network device at each of the time
moments. The first configuration information in the embodiments of
the present disclosure may directly indicate which frequency domain
resource is used by the terminal device to transmit the uplink data
to the network device at each of the time moments. Therefore, the
indication manner of the embodiment of the present disclosure is
more flexible.
[0111] In the embodiments of the present disclosure, with the
second configuration information, it is possible to change the
frequency domain resource and the time domain resource used by the
terminal device to perform the pre-scheduled service at a specified
time moment, while keeping other frequency domain resources for
transmitting the uplink data at other time moments unchanged.
Therefore, as compared with the related art, the changes are small
and the method is flexible.
[0112] In some embodiments, when the frequency domain resources
used by the terminal device to perform the pre-scheduled service
also have periodicity, the first configuration information may
specifically be {P1, F1, OF1; P2, F2, OF2; P3, F3, OF3 . . . , in
which a period of the frequency domain resource F1 is P1, and a
time domain offset from the starting time moment is OF1. That is to
say, the terminal device performs the pre-scheduled service using
the frequency domain resource F1 when the time interval OF1 has
elapsed since the starting time moment. Then, the pre-scheduled
service is performed using the frequency domain resource P1 once
every time when the time period P1 has elapsed. Other frequency
domain resources are similar to the case of the frequency domain
resource F 1. In addition, if OF1 is equal to zero, the terminal
device performs the pre-scheduled service using the frequency
domain resource F1 from the starting time moment.
[0113] Optionally, the first configuration information and the
second configuration information may be sent by the network device
through higher layer signaling or physical layer signaling.
[0114] The higher layer signaling here may be Radio Resource
Control (RRC) signaling, and the physical layer signaling may be
signaling that is sent on a Physical Downlink Control Channel
(PDCCH).
[0115] In some embodiments, the first configuration information
includes time domain resource indication information and frequency
domain resource indication information. The time domain resource
indication information is sent by the network device through higher
layer signaling, and the frequency domain resource indication
information is sent by the network device through physical layer
signaling.
[0116] Similarly, the second configuration information may also
include time domain resource indication information and frequency
domain resource indication information. The time domain resource
indication information is sent by the network device through higher
layer signaling, and the frequency domain resource indication
information is sent by the network device through physical layer
signaling.
[0117] The base station may configure a time moment list including
T1, T2, T3, . . . through RRC signaling, the time moment list
indicates that the terminal will have scheduled service at the time
moments indicated in the list. The base station may indicate, at a
scheduling time moment or in a previously negotiated time moment
before the scheduling time moment, a frequency domain resource for
performing the pre-scheduled service at the scheduled time moment
through physical signaling. In addition, the base station may also
indicate, at a time the frequency domain resource used by the
terminal device to perform the pre-scheduled service at multiple
time moments.
[0118] Specifically, the base station may indicate to the terminal,
at a time moment T1 and through PDCCH, the frequency domain
resource used to perform the pre-scheduled service at the time
moment T1. The base station may also indicate to the terminal, at a
predetermined time moment T1' before the time T1 and through PDCCH,
the frequency domain resource used to perform the pre-scheduled
service at the time moment T1. In addition, the base station may
indicate to the terminal at a time moment T1 and through PDCCH, the
frequency domain resources used to perform the pre-scheduled
service respectively at the time moments T1, T2 and T3.
Alternatively, the base station may indicate to the terminal, at a
predetermined time moment T1' before the time T1 and through PDCCH,
the frequency domain resources used to perform the pre-scheduled
service respectively at the time moments T1, T2 and T3.
[0119] In some embodiments, the method for scheduling a terminal
device further includes: the network device receiving a service
request message from the terminal device, and the service request
message indicates a time moment when the terminal device will
perform the pre-scheduled service and a size of data to be
transmitted for the pre-scheduled service. The network device
determining the first configuration information includes: the
network device determining the first configuration information
according to the service request message.
[0120] Specifically, the service request information may be
specifically in the form shown in Table 8. As shown in Table 8, the
terminal device needs to transmit a service with a data size of S1
at a time moment T1, and needs to transmit a service with a data
size of S2 at a time moment T2. After receiving the service request
message, the terminal device may determine the first configuration
information according to the service request message. For example,
the first configuration information may indicate that the terminal
device transmits the service with the data size of S1 at the time
moment T1 using a frequency domain resource F1, and transmits the
service with the data size of S2 at the time moment T2 using a
frequency domain resource F2.
[0121] In the embodiment of the present disclosure, the network
device can determine the time domain resource and the frequency
domain resource used by the terminal device to perform the
pre-scheduled service more reasonably according to the service
request message sent by the terminal device, so that the terminal
device can perform the pre-scheduled service in a more desirable
way.
[0122] For a terminal device or an Internet of Things terminal
device that performs machine-based communication with a relatively
fixed service demand, the terminal device may report in advance to
the network device through the service request message, the time
moment for transmitting the data and the size of data to be
transmitted. In this way, the network device may allocate resources
to the terminal at one time in a pre-scheduled manner to save
signaling overhead.
[0123] In some embodiments, the first configuration information may
include multiple pieces of indication information, and each of the
multiple pieces of indication information indicates a time domain
resource and a frequency domain resource used by the terminal
device to perform the pre-scheduled service. However, any two of
the multiple pieces of indication information indicate the time
domain resource and the frequency domain resource in different
indication manners. The method for scheduling a resource also
includes: the network device sending scheduling information to the
terminal device, where the scheduling information indicates that
the terminal device determines the time domain resource and the
frequency domain resource used to perform the pre-scheduled service
according to one of the multiple pieces of indication information.
That is, the first configuration information may carry indication
information with different indication manners, and scheduling
information sent by the network device to the terminal device
specifies which indication manner is selected to determine the time
domain resource and the frequency domain resource used for
performing the pre-scheduled service.
[0124] The method for scheduling a terminal device according to the
embodiments of the present disclosure has been described in detail
above with reference to FIG. 2 from the perspective of the network
device. The method for scheduling a terminal device according to
the embodiments of the present disclosure will be described in
detail below with reference to FIG. 3 from the perspective of the
terminal device.
[0125] It should be understood that the method for scheduling a
terminal according to the embodiments of the present disclosure
described from the perspective of the terminal device is
corresponding to the method for scheduling the terminal according
to the embodiments of the present disclosure from the perspective
of the network device, and the repeated description will be omitted
as appropriate for the sake of brevity.
[0126] FIG. 3 is a schematic flowchart of a method for scheduling a
terminal device according to an embodiment of the present
disclosure. The method of FIG. 3 includes the following steps.
[0127] In step 310, the terminal device receives first
configuration information from the network device. The first
configuration information indicates a time domain resource and a
frequency domain resource used by the terminal device to perform a
pre-scheduled service.
[0128] In step 320, the terminal device performs the pre-scheduled
service on the time domain resource and the frequency domain
resource indicated by the first configuration information.
[0129] In the embodiment of the present disclosure, the first
configuration information indicates the time domain resource and
the frequency domain resource used by the terminal device to
perform the pre-scheduled service. As compared with the method of
indicating only the transmission period and the frequency domain
for the pre-scheduled service to be performed by the terminal
device in the related art, the present disclosure can flexibly
schedule the terminal device to perform pre-scheduled service.
[0130] Optionally, the first configuration information may indicate
the time domain resource and the frequency domain resource used by
the terminal device to perform the pre-scheduled service in various
indication manners, specifically, in at least the following three
situations.
[0131] (1) The pre-scheduled service is a periodic service, and the
first configuration information indicates a transmission period of
the pre-scheduled service and a frequency domain resource used by
the terminal device to perform the pre-scheduled service at each of
the time moments. At at least two of the time moments, the terminal
device uses different frequency domain resources to perform the
pre-scheduled service.
[0132] (2) The pre-scheduled service is a non-periodic service, and
the first configuration information indicates each time moment for
the terminal device to perform the pre-scheduled service and the
frequency domain resource used by the terminal device to perform
the pre-scheduled service at each of the time moments. The terminal
device uses the same frequency domain resource to perform the
pre-scheduled service at each of the time moments.
[0133] (3) The first configuration information indicates each time
moment for the terminal device to perform the pre-scheduled service
and a respective frequency domain resource used by the terminal
device to perform the pre-scheduled service at each time
