frame, within the time domain length of the first symbol, the AGC
can be performed on the receiving amplifying circuit in the
communication apparatus according to the signal in the received
first symbol.
[0083] Certainly, when the communication apparatus, as the

AGC such that the gains of the corresponding transmission
amplifying circuit and the receiving amplifying circuit reach a
stable level, can be referred to as AGC settling time.
[0085] In the embodiment of the present disclosure, the time domain
length of the first symbol in the radio frame received or
transmitted by the communication apparatus may be greater than or
equal to the AGC settling time of the communication apparatus, so
that the communication apparatus can complete the AGC adjustment
within a time period of transmitting the signal corresponding to
the first symbol or receiving the signal corresponding to the first
symbol.
[0086] Specifically, when transmitting the radio frame, the
communication apparatus can transmit a radio frame, and a time
domain length of the first symbol in the radio frame exceeds the
time domain length of any one of the remaining symbols and the time
domain length of the first symbol is greater than or equal to the
AGC settling time of the communication apparatus. When receiving
the radio frame, the communications apparatus can receive a radio
frame in which a time domain length of the first symbol exceeds the
time domain length of any one of the remaining symbols and is
greater than or equal to the AGC settling time of the communication
apparatus.
[0087] The following takes the current AGC settling time (about 20
us to 66.67 us) as an example, and introduces the radio frame of
the embodiment of the present disclosure in conjunction with the
frame structure shown in FIG. 3. As shown in FIG. 3, the interval
of the radio frame transmitted or received by the communication
apparatus is 120 kHz, and the time domain length of any one of the
remaining symbols in the radio frame is 1/(15 kHz)/8 except the
first symbol, the time domain length of the first symbol is 1/(15
kHz), which is about 66.67 us.
[0088] When the communication apparatus transmits the frame as
shown in FIG. 3, since the time domain length 66.67 us of the first
symbol is greater than the lower limit time 20 us of the AGC
settling time of the communication apparatus, therefore the
communication apparatus can complete the AGC adjustment of the
transmission amplifying circuit based on the signal transmitted
within a time period of transmitting the signal corresponding to
the first symbol. When the communication apparatus receives the
frame shown in FIG. 3, since the time domain length 66.67 us of the
first symbol is greater than the lower limit time 20 us of the AGC
settling time of the communication apparatus, therefore the
communication apparatus can complete the AGC adjustment of the
receiving amplifying circuit based on the signal received within a
time period of receiving the signal corresponding to the first
symbol.
[0089] In general, when the carrier interval of the radio frame is
15*2.sup.k kHz, the time domain length of any one of the remaining
symbols in the radio frame may be 1/(15 kHz)/2.sup.k except the
first symbol. At this time, an optional value of the time domain
length of the first symbol is 1/(15 kHz).
[0090] In the embodiment of the present disclosure, the first
symbol of the radio frame may use a specified sequence, i.e., a
sequence carried by the first symbol is known to the communication
apparatus. Specifically, the sequence carried by the first symbol
in the radio frame is a sequence that is known or pre-agreed in
advance to the communication apparatuses that transmit and receive
the radio frame, i.e., the information carried by the first symbol
is known to the communication apparatuses at both ends of the
communication. The sequence may be configured to the communication
apparatus by the base station or may be preset on the communication
apparatus.
[0091] When the sequence carried by the first symbol in the radio
frame is known, the communication apparatus (the user equipment
shown in FIG. 1), as the receiving end, can also perform channel
estimation by using the signal corresponding to the first
symbol.
[0092] FIG. 4 schematically illustrates a communication method
according to an embodiment of the present disclosure. It should be
understood that FIG. 4 illustrates steps or operations of the
communication method, but these steps or operations are merely
examples, and embodiments of the present disclosure may perform
other operations or variations of the various operations in FIG.
4.
[0093] In step S410, a communication apparatus generates a radio
frame, all symbols in the radio frame have a same time domain
length; and sequences carried by first M symbols in the radio frame
are known to the communication apparatus, wherein M is a positive
integer.
[0094] In other words, the first M symbols in the radio frame carry
known sequences, and the time domain length of the symbols in the M
symbols is equal to the time domain length of any one of the
remaining symbols, which both are 1/(15 kHz)/2.sup.k.
[0095] The communication apparatus, as a receiving end, may be the
base station shown in FIG. 1, or may be the UE shown in FIG. 1. The
symbols in the radio frame may be OFDM symbols. The radio frame may
also be a frame for short. The first M symbols of the radio frame
refer to consecutive M symbols in the radio frame starting from the
start position thereof.
[0096] In step S420, the communication apparatus transmits the
radio frame.
[0097] In the embodiment of the present disclosure, the
communication apparatus can communicate with other communication
apparatuses by transmitting the radio frame of known sequences
carried by first M symbols.
[0098] Optionally, a time domain length of each symbol in the radio
frame is 1/(15 kHz)/2.sup.k, wherein k is a positive integer.
[0099] FIG. 4 schematically illustrates a communication method
according to an embodiment of the present disclosure. At the
corresponding receiving end, the communication apparatus receives
the radio frame, and all symbols in the second radio frame have a
same time domain length, and sequences carried by first M symbols
in the radio frame are known to the communication apparatus. Then
the communication apparatus can perform a processing based on the
radio frame.
[0100] In the embodiment of the present disclosure, the
communication apparatus, as the receiving end, can communicate with
other communication apparatuses by receiving the radio frame of
known sequences carried by first M symbols.
[0101] The communication apparatus, as the receiving end, may be
the base station as illustrated in FIG. 1, or may be the user
equipment as illustrated in FIG. 1. The symbol in the radio frame
may be OFDM symbol. The processing, which is performed by the
communication apparatus based on the radio frame, may include
performing AGC based on the first M symbols in the radio frame. In
other words, when the communication apparatus receives the radio
frame, within the time domain length of the first M symbols, the
AGC can be performed on the receiving amplifying circuit in the
communication apparatus according to the signal in the received
first M symbols.
[0102] Certainly, when the communication apparatus, as the
transmitting end, transmits the radio frame, within the time domain
length of the first M symbols, the AGC can be performed on the
transmission amplifying circuit in the communication apparatus
according to the signal in the transmitted first M symbols.
[0103] In the embodiment of the present disclosure, the time domain
length of the first M symbols in the radio frame received or
transmitted by the communication apparatus may be greater than or
equal to the AGC settling time of the communication apparatus, so
that the communication apparatus can complete the AGC adjustment
within a time period of transmitting the signal corresponding to
the first M symbols or receiving the signal corresponding to the
first M symbols.
[0104] Specifically, when transmitting the radio frame, the
communication apparatus can transmit known sequences carried by the
first M symbols in a radio frame, and a time domain length of the
first M symbols is greater than or equal to the AGC settling time
of the communication apparatus. When receiving the radio frame, the
communications apparatus can receive known sequences carried by the
first M symbols in the radio frame, and the time domain length of
the first M symbols is greater than or equal to the AGC settling
time of the communication apparatus.
[0105] The following takes the current AGC settling time (about 20
us to 66.67 us) as an example, and introduces the radio frame of
the embodiment of the present disclosure in conjunction with the
frame structure shown in FIG. 5. As shown in FIG. 5, the interval
of the radio frame transmitted or received by the communication
apparatus is 60 kHz, and the time domain length of all symbols in
the radio frame is 1/(15 kHz)/4, the total time domain length of
the first 4 symbols is 1/(15 kHz) (i.e., M=4), and the first 4
symbols carry known sequences.
[0106] When the communication apparatus transmits the frame shown
in FIG. 5, since the total time domain length 1/14 millisecond of
the first 4 symbols is greater than the lower limit time 20 us of
the AGC settling time of the communication apparatus, and the
sequences carried by the first 4 symbols are known, therefore the
communication apparatus can complete the AGC adjustment of the
transmission amplifying circuit based on the signal transmitted
within a time period of transmitting the signal corresponding to
the first 4 symbols. When the communication apparatus receives the
frame shown in FIG. 5, since the total time domain length 1/(15
kHz) of the first 4 symbols is greater than the lower limit time 20
us of the AGC settling time of the communication apparatus, and the
sequences carried by the first 4 symbols are known, therefore the
communication apparatus can complete the AGC adjustment of the
receiving amplifying circuit based on the received signal within a
time period of receiving the signal corresponding to the first 4
symbols.
[0107] In general, when the carrier interval of the radio frame is
15*2.sup.k kHz, the time domain length of all symbols in the radio
frame may be 1/(15 kHz)/2.sup.k. At this time, an optional value of
the total time domain length of the first M symbols is 1/(15
kHz).
[0108] In the embodiment of the present disclosure, sequences
carried by the first M symbols in the radio frame are known, i.e.,
the first M symbols in the radio frame carry specified sequences.
Specifically, the sequences carried by the first M symbols in the
radio frame are known or pre-agreed in advance to the communication
apparatuses that transmit and receive the radio frame, i.e., the
information carried by the first M symbols are known to the
communication apparatuses at both ends of the communication. The
sequence may be configured to the communication apparatus by the
base station or may be preset on the communication apparatus.
[0109] Moreover, sine the sequence carried by the first M symbols
in the radio frame are known, the communication apparatus (the user
equipment shown in FIG. 1), as the receiving end, can also perform
channel estimation by using the signal corresponding to the first M
symbols.
[0110] In above embodiments of the present disclosure, the time
domain length of the first symbol in the radio frame is greater
than the time domain length of any one of the remaining symbols,
the first symbol in the radio frame may be referred to as a
training symbol; all symbols in the radio frame have the same time
domain length and the first M symbols carry known sequences, the
first M symbols in the radio frame may also be collectively
referred to as training symbols.
[0111] In an embodiment of the present disclosure, optionally, when
a communication apparatus continuously transmits a plurality of
radio frames (including an uplink frame and a downlink frame), not
all radio frames are required to include a training symbol, but
only the first radio frame among the plurality of consecutive radio
frames may include a training symbol, and any one of the remaining
radio frames may not include a training symbol.
[0112] Specifically, when the communication apparatus continuously
transmits a plurality of radio frames, the time domain length of
the first symbol in the first radio frame is greater than the time
domain length of any one of the remaining symbols in the radio
frame. Starting from the second radio frame, all the symbols in the
radio frame have the same time domain length; or all the symbols in
each radio frame of the plurality of consecutive radio frames have
the same time domain length, but only the first M symbols in the
first radio frame carry known sequences.
[0113] When the communication apparatus, such as the user
equipment, is required to continuously transmit a plurality of
radio frames, the base station may transmit a scheduling
instruction (or indication information) to the terminal apparatus
to indicate that the terminal apparatus transmits information of
symbols in the plurality of radio frames; The apparatus receives
information, transmitted by the base station, to indicate symbols
in the radio frame. For example, the base station transmits a
scheduling instruction to the terminal apparatus to indicate
whether the first radio frame of the plurality of radio frames,
transmitted by the terminal apparatus to the base station, includes
training symbols, i.e., the terminal apparatus is indicated to
transmit a radio frame to the base station, and a time domain
length of the first symbol in the radio frame is greater than the
time domain length of any one of the remaining symbols, or the
terminal apparatus is indicated to transmit a radio frame to the
base station, and all the symbols in the radio frame have the same
time domain length, and the first M symbols in the radio frame
carry known sequences. If the first radio frame includes training
symbols, the base station may further transmit a scheduling
instruction to the terminal apparatus to indicate the number
information of symbols occupied by the training symbols in the
radio frame and the time domain length information of the training
symbols, and/or indicate whether any one of the remaining radio
frames includes a training symbol. Correspondingly, the terminal
apparatus receives the scheduling instruction transmitted by the
base station.
[0114] Optionally, when a base station is required to continuously
transmit a plurality of radio frames to the terminal apparatus, the
base station may transmit a scheduling instruction to the terminal
apparatus to indicate that the base station transmits the
information of symbols in the plurality of radio frames, so that
terminal apparatus receives the plurality of radio frames based on
the information of the symbols. For example, the base station
transmits a scheduling instruction to the terminal apparatus to
indicate whether the first radio frame of the plurality of radio
frames, transmitted by the terminal apparatus to the base station,
includes training symbols. If the first radio frame includes
training symbols, the base station may further transmit a
scheduling instruction to the terminal apparatus to indicate the
number information of symbols occupied by the training symbols in
the radio frame and the time domain length information of the
training symbols, and/or indicate whether any one of the remaining
radio frames includes a training symbol. Correspondingly, the
terminal apparatus receives the scheduling instruction transmitted
by the base station.
[0115] For example, when the terminal apparatus is required to
control the transmit power, i.e., the terminal apparatus is
required to increase or decrease the transmit power of some radio
frames. The terminal apparatus may transmit the first radio frame,
which includes training symbols, of these radio frames according to
the indication of the scheduling instruction of the base station.
Specifically, the time domain length of the first symbol in the
first radio frame transmitted by the terminal apparatus is greater
than the time domain length of any one of the remaining symbols; or
the time domain length of all symbols in the first radio frame
transmitted by the terminal apparatus is equal, and the first M
symbols carry known sequences.
[0116] In an embodiment of the present disclosure, when a
communication system in which a communication apparatus is located
can support multiple numerologies, different numerologies can
correspond to radio frames of different structures, i.e., a
communication apparatus in a communication system can use various
communication methods. In other words, when a plurality of
numerologies are supported in the communication system, the
communication apparatus, as the transmitting end, can communicate
with other communication apparatuses using both the communication
method shown in FIG. 2 and the communication method shown in FIG.
4.
[0117] For example, when the communication apparatus supports
multiple numerologies, the communication apparatus may generate a
radio frame in which the time domain length of the first symbol is
greater than the time domain length of any one of the remaining
symbols, and transmit the radio frame; then the communication
apparatus may also generate a radio frame in which all symbols have
the same time domain length and the sequences carried by the first
M symbols are known to the communication apparatus, and transmit
the radio frame.
[0118] Correspondingly, the communication apparatus, as the
receiving end, can receive not only the radio frame in which the
time domain length of the first symbol is greater than the time
domain length of any one of the remaining symbols, and perform a
processing based on the radio frame, but also the radio frame in
which all symbols have the same time domain length and the
sequences carried by the first M symbols are known to the
communication apparatus, and perform a processing based on the
radio frame.
[0119] For example, when there are two subcarrier intervals of 120
kHz and 60 kHz in the communication system, if the communication
apparatus communicates with other communication apparatuses through
the subcarrier interval of 120 kHz, the communication apparatus can
generate a radio frame in which the time domain length of the first
symbol is greater than the time domain of any one of the remaining
symbols, and transmit the radio frame. If the communication
apparatus communicates with other communication apparatuses through
the subcarrier interval of 60 kHz, the communication apparatus can
generate a radio frame in which all symbols have the same time
domain length and the sequences carried by the first M symbols are
known to the communication apparatus.
[0120] For example, the base station can inform (e.g., by broadcast
or dedicated signaling) information of the numerology used in the
current communication system to the terminal apparatus. The base
station may also use broadcast or dedicated signaling to inform the
terminal apparatus to use the radio frame, in which the time domain
length of the first symbol is greater than the time domain length
of any one of the remaining symbols, and/or all symbols have the
same time domain length and the sequences carried by the first M
symbols are known to the communication apparatus, to communicate
with the base station,
