Technical Field

The embodiments of the present disclosure relate to the field of communication technology, and in particular to a communication processing method, apparatus, device, and readable storage medium.

Background Art

Existing base stations use time division multiplexing (TDM) on a time division duplexing (TDD) carrier to perform uplink and downlink multiplexing transmission. Due to the limited uplink duty cycle, the uplink coverage performance and uplink and downlink delays of the terminal (for example, user equipment (UE)) are subject to the limitations of the TDD uplink and downlink configuration. In the related art, subband full duplex (SBFD) is to configure a part of the time slot or symbol into a SBFD time slot (slot) or symbol (symbol), that is, a part of the frequency resources of the bandwidth part (BWP) is used as the uplink subband (SBFD-UL subband) of SBFD, UL refers to uplink (Uplink), and subband refers to subband. The other part of the frequency resources is used as the downlink subband (SBFD-DL subband) of SBFD, DL refers to downlink (Downlink). When the base station transmits on an SBFD symbol, the base station can receive uplink signals on the SBFD-UL subband while transmitting downlink signals on the SBFD-DL subband, thereby achieving simultaneous uplink and downlink transmission and reception on the base station side. A typical SBFD schematic diagram is shown in Figure 1.

The current TDD downlink channel state information (CSI) feedback method is designed for downlink use when all frequency resources within the BWP are for downlink. If the communication system supports SBFD operation, the existing CSI feedback method cannot be used directly. Therefore, how to improve the accuracy and effectiveness of downlink channel state information feedback is an urgent problem to be solved.

Step 401: Receive third information, wherein the third information is used to indicate that the channel state information feedback configuration is used for at least one of the following: (1) used to determine the CSI feedback corresponding to the situation where PDSCH is transmitted in the SBFD time unit; or, (2) used to determine the CSI feedback corresponding to the situation where PDSCH is transmitted in the non-SBFD time unit; or, (3) used to determine the CSI feedback corresponding to the situation where PDSCH is transmitted in the SBFD time unit, and can be used to determine the CSI feedback corresponding to the situation where PDSCH is transmitted in the non-SBFD time unit.

In an embodiment of the present disclosure, when the value of the third information is a first value (for example, "00" or "0"), the third information indicates that the channel state information feedback configuration is used to determine the CSI feedback corresponding to the situation where the PDSCH is transmitted in the SBFD time unit, and the method further includes:

Based on the fifth NZP CSI-RS opportunity in the SBFD time unit in the time domain, channel measurement is performed, and the channel measurement is used to determine the CSI fed back at the fifth time (for example, time slot n, the value of n is not limited), and the fifth NZP CSI-RS opportunity is no later than the reference resource of the CSI.

The fifth time mentioned above is used to indicate the moment of feeding back CSI.

In an embodiment of the present disclosure, when the value of the third information is the second value (for example, "01" or "1"), the channel state information feedback configuration is used to determine the CSI feedback corresponding to the situation where the PDSCH is transmitted in the non-SBFD time unit, and the method further includes:

Based on the sixth NZP CSI-RS opportunity in the non-SBFD time unit in the time domain, channel measurement is performed, and the channel measurement is used to determine the CSI fed back at a sixth time (for example, time slot n, the value of n is not limited), and the sixth NZP CSI-RS opportunity is no later than the reference resource of the CSI.

The sixth time mentioned above is used to indicate the moment of feeding back CSI.

In an embodiment of the present disclosure, when the value of the third information is a third value (for example, "10" or "1"), the third information indicates that the channel state information feedback configuration is used to determine both the CSI feedback corresponding to the case where the PDSCH is transmitted in the SBFD time unit and the CSI feedback corresponding to the case where the PDSCH is transmitted in the non-SBFD time unit, and the restriction of the channel measurement in the time domain in the channel state information feedback configuration is set to configured, and the method further includes:

Based on the most recent seventh NZP CSI-RS opportunity, channel measurement is performed, the channel measurement is used to determine the CSI fed back at the seventh time (for example, time slot n, the value of n is not limited), the seventh NZP CSI-RS opportunity is no later than the reference resource of the CSI, and the most recent seventh NZP CSI-RS opportunity is within the non-SBFD time unit in the time domain, or is within the SBFD time unit.

The seventh time mentioned above is used to indicate the time of feeding back CSI.

It can be understood that the fifth time, the sixth time and the seventh time may be the same or different.

In one embodiment of the present disclosure, the most recent seventh NZP CSI-RS opportunity is in the time domain In the case of a SBFD time unit, the method further comprises:

The CSI associated with the target bit is not fed back, or a specific CSI value is fed back as the CSI associated with the target bit;

The target bits include: one or more bits corresponding to the CSI-ReportingBand in the channel state information feedback configuration, and corresponding to multiple CSI subbands that are completely contained in the SBFD-UL subband in the frequency domain.

For example, if the most recent seventh NZP CSI-RS opportunity is within the SBFD symbols or slots in the time domain, the UE ignores the values of several target bits corresponding to several CSI subbands completely included in the SBFD-UL subband in the frequency domain in the bits corresponding to the csi-ReportingBand in the CSI-ReportConfig. Even if there is a target bit with a value of '1' among the several bits, the UE may not feedback the CSI associated with the target bit, or the UE may use some special CSI values as the CSI associated with the target bit for feedback.

The embodiments of the present disclosure can meet the needs of channel state information feedback of a communication system supporting SBFD operation, help improve the accuracy and effectiveness of downlink channel state information feedback, and help improve the downlink performance of the communication system.

5 , an embodiment of the present disclosure provides a communication processing method, which is applied to a network side device, and the specific steps include: Step 501 .

Step 501: Send third information, wherein the third information is used to indicate that the channel state information feedback configuration is used for at least one of the following: (1) used to determine the CSI feedback corresponding to the situation where PDSCH is transmitted in the SBFD time unit; or, (2) used to determine the CSI feedback corresponding to the situation where PDSCH is transmitted in the non-SBFD time unit; or, (3) used to determine the CSI feedback corresponding to the situation where PDSCH is transmitted in the SBFD time unit, and can be used to determine the CSI feedback corresponding to the situation where PDSCH is transmitted in the non-SBFD time unit.

In an implementation manner of the present disclosure, when the value of the third information is the first value, the third information indicates that the channel state information feedback configuration is used to determine CSI feedback corresponding to a situation in which the PDSCH is transmitted in a SBFD time unit.

In an embodiment of the present disclosure, when the value of the third information is the second value, the channel state information feedback configuration is used to determine the CSI feedback corresponding to the situation where the PDSCH is transmitted in a non-SBFD time unit.

In one embodiment of the present disclosure, when the value of the third information is the third value, the third information indicates that the channel state information feedback configuration is used to determine both the CSI feedback corresponding to the situation where PDSCH is transmitted in an SBFD time unit and the CSI feedback corresponding to the situation where PDSCH is transmitted in a non-SBFD time unit, and the channel measurement restriction in the time domain in the channel state information feedback configuration is set to configured.

The embodiments of the present disclosure can meet the needs of channel state information feedback of a communication system supporting SBFD operation, help improve the accuracy and effectiveness of downlink channel state information feedback, and help improve the downlink performance of the communication system.

To facilitate understanding of the following embodiments (Embodiment 1 to Embodiment 9), the meanings of terms such as “X bits”, “N original CSI subbands”, “M original CSI subbands”, “L original CSI subbands”, “N-M original CSI subbands”, and “N-M-L original CSI subbands” are first introduced.

(1) “X bits”: defined as the channel state information feedback configuration (CSI-ReportConfig) configured by the base station for the terminal The X bits corresponding to the csi-ReportingBand in .

(2) “N original CSI subbands”: defined as the N CSI subbands included in the BWP.

(3) “M original CSI subbands”: defined as the M complete CSI subbands that belong to the N CSI subbands included in the BWP and are completely contained in the SBFD-UL subband (or in the SBFD-UL subband and Guard subbands, if there are Guard subbands) in the frequency domain.

(4) “L original CSI subbands”: defined as the L CSI subbands that belong to the N CSI subbands included in the BWP and partially overlap with the SBFD-DL subbands in the frequency domain (i.e., each CSI subband in the L CSI subbands has a part overlapping with the SBFD-DL subband in the frequency domain, and another part overlapping with the SBFD-UL subband and/or Guard subband in the frequency domain).

(5) “N-M original CSI subbands”: defined as the N-M CSI subbands that belong to the N CSI subbands included in the BWP and do not belong to the “M original CSI subbands”.

(6) “N-M-L CSI subbands”: defined as the N-M-L CSI subbands that belong to the N CSI subbands included in the BWP and do not belong to the “M original CSI subbands” and “L original CSI subbands”.

Embodiment 1:

Assume that the number of bits corresponding to the csi-ReportingBand in the CSI-ReportConfig configured by the base station for the terminal is X, the number of CSI subbands included in the BWP is N, the number of complete CSI subbands included in the SBFD-UL subband (or in the SBFD-UL subband and Guard subbands, if there are Guard subbands) is M (that is, each of the M CSI subbands is completely located inside the SBFD-UL subband and/or Guard subband in the frequency domain), and the number of CSI subbands that partially overlap with the SBFD-DL subbands in the frequency domain is L (that is, each of the L CSI subbands has a part that overlaps with the SBFD-DL subband in the frequency domain, and another part that overlaps with the SBFD-UL subband and/or Guard subband in the frequency domain), then X can be taken as N-M or N-M-L.

Embodiment 2:

Assuming M>0 and L>0, when X=N-M (that is, when the csi-ReportingBand in the CSI-ReportConfig configured by the base station for the terminal corresponds to N-M bits), "X bits" indicate N-M redefined CSI subbands (there is a one-to-one correspondence between X bits and N-M redefined CSI subbands), and the N-M redefined CSI subbands include "N-M-L original CSI subbands" and L redefined CSI subbands after redefining the "L original CSI subbands".

The method to redefine “L original CSI subbands” is:

For the L original CSI subbands, only the parts overlapping with the SBFD-DL subbands are retained in the frequency domain, that is, L redefined CSI subbands are obtained. The order of the NM redefined CSI subbands when corresponding to the X bits one by one is consistent with the order in which they are arranged in the BWP. The base station and the UE understand the CSI-ReportConfig as follows: the CSI-ReportConfig is only used to determine the CSI feedback corresponding to the situation where the PDSCH is transmitted in the SBFD slot. At this time, the channel measurements (channel measurements) performed by the UE to calculate the CSI fed back at time slot n are only based on the NZP CSI-RS opportunity in the SBFD symbols/slots in the time domain, and the NZP CSI-RS opportunity is no later than the reference resource (CSI reference resource) of the CSI.

Example of Embodiment 2:

Taking BWP=275PRBs, 2 SBFD-DL subbands (111PRBs and 110PRBs), 1 SBFD-DL subband (50PRBs), 2 Guard subbands (2PRBs each), and CSI subband size=32PRBs as an example, the number of original CSI subbands contained in BWP and their numbering are shown in Figure 6, where BWP=275PRBs, 2 SBFD-DL subbands (111PRBs and 110PRBs), 1 SBFD-UL subband (50PRBs), 2 Guard subbands (2PRBs each), and CSI subband size=32PRBs. The BWP contains 9 original CSI subbands, N=9, M=1, and L=2.

When X=N-M=8 (i.e., when the base station configures the 8 bits corresponding to the csi-ReportingBand in the CSI-ReportConfig for the terminal), the "X bits" indicate 8 redefined CSI subbands (there is a one-to-one correspondence between the 8 bits and the 8 redefined CSI subbands), the 8 redefined CSI subbands include "N-M-L original CSI subbands" (i.e., {CSI subband#1, CSI subband#2, CSI subband#3, CSI subband#7, CSI subband#8, CSI subband#9}) and L redefined CSI subbands after the redefinition of "L original CSI subbands" (i.e., {CSI subband#4, CSI subband#6}). The method of redefining "the L original CSI subbands" (i.e., {CSI subband#4, CSI subband#6}) is as follows: CSI subband#4 and CSI subband#6 only retain the parts that overlap with the SBFD-DL subbands in the frequency domain as redefined CSI subbands. Figure 7 is a schematic diagram of N-M redefined CSI subbands indicated by "X bits" (redefined CSI subbands are represented by "CSI subband#i'"). Among them, N-M redefined CSI subbands are {CSI subband#1’=CSI subband#1, CSI subband#2’=CSI subband#2, CSI subband#3’=CSI subband#3, CSI subband#4’=redefined CSI su bband#4, CSI subband#5’=redefined CSI subband#6, CSI subband#6’=CSI subband#7, CSI subband#7’=CSI subband#8, CSI subband#8’=CSI subband#9}, 8 bits correspond to them one-to-one.

Embodiment 3:

Assuming that M>0 and L>0, when X=N-M-L (i.e., when the csi-ReportingBand in the CSI-ReportConfig configured by the base station for the terminal corresponds to N-M-L bits), "X bits" indicate N-M-L redefined CSI subbands (there is a one-to-one correspondence between the X bits and the N-M-L redefined CSI subbands), and the N-M-L redefined CSI subbands are the "N-M-L original CSI subbands". The order in which the N-M-L redefined CSI subbands correspond to the X bits is consistent with the order in which they are in the BWP.

The base station and UE understand the CSI-ReportConfig as follows: the CSI-ReportConfig is only used to determine the CSI feedback corresponding to the situation where PDSCH is transmitted in the SBFD slot. At this time, the channel measurements performed by the UE to calculate the CSI fed back at time slot n are only based on the NZP CSI-RS timing in the SBFD symbols or slots in the time domain, and the NZP CSI-RS timing is not later than the CSI reference resource.

Example of Embodiment 3: Based on the situation shown in FIG6 ,

When X=NML=6 (i.e., when the base station configures the UE with 6 bits corresponding to the csi-ReportingBand in the CSI-ReportConfig), "X bits" indicate 6 redefined CSI subbands (there is a one-to-one correspondence between the 6 bits and the 6 redefined CSI subbands), and the 6 redefined CSI subbands are "NML original CSI subbands". (i.e., {CSI subband#1, CSI subband#2, CSI subband#3, CSI subband#7, CSI subband#8, CSI subband#9}). Figure 8 is a schematic diagram of NML redefined CSI subbands indicated by "X bits" (redefined CSI subbands are denoted by "CSI subband#i"). The NML redefined CSI subbands are {CSI subband#1"＝CSI subband#1, CSI subband#2"＝CSI subband#2, CSI subband#3"＝CSI subband#3, CSI subband#4"＝CSI subband#7, CSI subband#5"＝CSI subband#8, CSI subband#6"＝CSI subband#9}, and the 6 bits correspond to them one by one.

Embodiment 4:

Assuming that M>0 and L>0, when X=N (i.e., when the csi-ReportingBand in the CSI-ReportConfig configured by the base station for the terminal corresponds to N bits), the "X bits" shown in Figure 9 indicate N redefined CSI subbands (there is a one-to-one correspondence between the X bits and the N redefined CSI subbands), and the N redefined CSI subbands are the "N original CSI subbands". The order of the N redefined CSI subbands when corresponding to the X bits one-to-one is consistent with the order of their arrangement in the BWP.

The base station and UE understand the CSI-ReportConfig as follows: the CSI-ReportConfig is only used to determine the CSI feedback corresponding to the case where PDSCH is transmitted in a non-SBFD slot. At this time, the channel measurements performed by the UE to calculate the CSI fed back at time slot n are only based on the NZP CSI-RS timing in the non-SBFD symbols/slots in the time domain, and the NZP CSI-RS timing is not later than the CSI reference resource.

Embodiment 5:

Assuming M>0 and L>0, when X=N (i.e., when the csi-ReportingBand in the CSI-ReportConfig configured by the base station for the terminal corresponds to N bits), "X bits" indicate N redefined CSI subbands (there is a one-to-one correspondence between X bits and N redefined CSI subbands), the base station can indicate to the UE through signaling (e.g., 1-bit indication) whether the CSI-ReportConfig can be dynamically used for both "determining the CSI feedback corresponding to the situation where PDSCH is transmitted in a non-SBFD slot" and "determining the CSI feedback corresponding to the situation where PDSCH is transmitted in a SBFD slot".

If the base station instructs the UE through signaling (for example, bit ‘0’) that the CSI-ReportConfig is not enabled to be dynamically used for both “determining the CSI feedback corresponding to the situation where PDSCH is transmitted in a non-SBFD slot” and “determining the CSI feedback corresponding to the situation where PDSCH is transmitted in a SBFD slot”, then by default, the CSI-ReportConfig is only used for “determining the CSI feedback corresponding to the situation where PDSCH is transmitted in a non-SBFD slot”, and the N redefined CSI subbands are the “N original CSI subbands”. At this time, the channel measurements performed by the UE to calculate the CSI fed back at time slot n are only based on the NZP CSI-RS timing in the non-SBFD symbols or slots in the time domain, and the NZP CSI-RS timing is no later than the CSI reference resource of the CSI.

If the base station indicates to the UE through signaling (e.g. bit '1') that the CSI-ReportConfig can be dynamically used for both "determining the CSI feedback corresponding to the case where PDSCH is transmitted in a non-SBFD slot" and "determining the CSI feedback corresponding to the case where PDSCH is transmitted in a SBFD slot", then timeRestrictionForChannelMeasurements in the CSI-ReportConfig should be set to "Configured". In this case, the channel measurements performed by the UE to calculate the CSI fed back at time slot n are only based on the most recent NZP CSI-RS timing. (the most recent occasion of NZP CSI-RS), and the NZP CSI-RS occasion is no later than the reference resource of the CSI (CSI reference resource).

If the nearest NZP CSI-RS opportunity is in a non-SBFD symbol or slot in the time domain, the N redefined CSI subbands are the "N original CSI subbands". At this time, the UE cannot ignore the values of the M bits corresponding to the "M original CSI subbands" in the X bits, and the UE needs to determine whether to feed back the associated CSI based on the values of these M bits.

If the most recent NZP CSI-RS opportunity is within the SBFD symbols or slots in the time domain, the N redefined CSI subbands include "N-M-L original CSI subbands", "M original CSI subbands", and L redefined CSI subbands after redefining the "L original CSI subbands". The method for redefining the "L original CSI subbands" is: for the L original CSI subbands, only the parts overlapping with the SBFD-DL subbands are retained in the frequency domain, that is, L redefined CSI subbands are obtained. At this time, the UE ignores the values of the M bits corresponding to the "M original CSI subbands" in the X bits. Even if there is a bit with a value of '1' among these M bits, the UE may not feedback the CSI associated with it, or the UE may use some special CSI values as the CSI associated with it for feedback.

In some cases (for example, when the CSI is fed back on the Physical Uplink Control Channel (PUCCH)), in order to keep the number of bits occupied by the CSI fed back by the UE fixed, at this time, when determining the number of bits occupied by the CSI fed back by the UE, it is necessary to consider the values of the M bits corresponding to the "M original CSI subbands" in the X bits (that is, they cannot be ignored).

Optionally, the UE may report a terminal capability indication, which is used to instruct the network whether the UE supports dynamically using a CSI-ReportConfig to "determine the CSI feedback corresponding to the situation where PDSCH is transmitted in a non-SBFD slot" and "determine the CSI feedback corresponding to the situation where PDSCH is transmitted in a SBFD slot".

Embodiment 6:

Assuming that M>0 and L=0, when X=N-M (i.e., when the csi-ReportingBand in the CSI-ReportConfig configured by the base station for the terminal corresponds to N-M bits), similar to the above-mentioned embodiment 2, "X bits" indicate N-M redefined CSI subbands (there is a one-to-one correspondence between the X bits and the N-M redefined CSI subbands), and the N-M redefined CSI subbands are the "N-M original CSI subbands". However, at this time, there are no "the L original CSI subbands" and the L bits associated therewith, so the content related to these L bits in the above-mentioned embodiment 2 is not applicable, and the description and understanding of the rest of the embodiment 2 are applicable.

Embodiment 7:

Assuming that M>0 and L=0, when X=N (i.e., when the csi-ReportingBand in the CSI-ReportConfig configured by the base station for the terminal corresponds to N bits), similar to the above-mentioned Embodiment 4 or Embodiment 5, "X bits" indicate N redefined CSI subbands (there is a one-to-one correspondence between the X bits and the N redefined CSI subbands). However, at this time, there are no "L original CSI subbands" and the L bits associated therewith, so the content related to these L bits in the above-mentioned Embodiment 4 or Embodiment 5 is not applicable, and the description and understanding of the rest of Embodiment 4 or Embodiment 5 are applicable.

Embodiment 8:

Assuming that M=0 and L>0, when X=N (i.e., when the csi-ReportingBand in the CSI-ReportConfig configured by the base station for the terminal corresponds to N bits), similar to the above-mentioned Embodiment 4 or Embodiment 5, "X bits" indicate N redefined CSI subbands (there is a one-to-one correspondence between the X bits and the N redefined CSI subbands). However, at this time, there are no "M original CSI subbands" and M bits associated therewith in the X bits, so the content related to these M bits in the above-mentioned Embodiment 4 or Embodiment 5 is not applicable, and the description and understanding of the rest of Embodiment 4 or Embodiment 5 are applicable.

Embodiment 9:

Assuming M=0 and L>0, when X=N-L (i.e., when the csi-ReportingBand in the CSI-ReportConfig configured by the base station for the terminal corresponds to N-L bits), "X bits" indicate N-L redefined CSI subbands (there is a one-to-one correspondence between the X bits and the N-L redefined CSI subbands), and the N-L redefined CSI subbands are "the N-M-L original CSI subbands". The order in which the N-L redefined CSI subbands correspond one-to-one to the X bits is consistent with the order in which they are in the BWP. The base station and UE understand the CSI-ReportConfig as follows: the CSI-ReportConfig is only used to determine the CSI feedback corresponding to the situation where PDSCH is transmitted in the SBFD slot. At this time, the channel measurements performed by the UE to calculate the CSI fed back at slot n are only based on the NZP CSI-RS timing in the SBFD symbols/slots in the time domain, and the NZP CSI-RS timing is no later than the CSI reference resource.
