[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to Chinese Patent Application No. 202311605118.2 filed in China on November 28, 2023, the entire contents of which are incorporated herein by reference. Technical Field

[0003] 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

[0004] 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 latency of the terminal (for example, user equipment (UE)) are subject to the limitations of the TDD uplink and downlink configuration. In related technologies, subband full duplex (SBFD) is to configure a portion of time slots or symbols as SBFD time slots or symbols, that is, a portion of the frequency resources of the bandwidth part (BWP) is used as the uplink subband (SBFD-UL subband) of SBFD, where UL refers to uplink and subband refers to subband. The other portion of the frequency resources is used as the downlink subband (SBFD-DL subband) of SBFD, where DL refers to downlink. When a base station transmits on an SBFD symbol, it can simultaneously transmit downlink signals on the SBFD-DL subband and receive uplink signals on the SBFD-UL subband, thereby achieving simultaneous uplink and downlink transmission and reception on the base station side. A typical SBFD diagram is shown in Figure 1.

[0005] The current TDD downlink channel state information (CSI) feedback method is designed for downlink use when all frequency resources within the BWP are used. If the communication system supports SBFD operation, the existing CSI feedback method cannot be directly used. Therefore, how to improve the accuracy and effectiveness of downlink channel state information feedback is an urgent problem to be solved.

[0090] The following will clearly and completely describe the technical solutions in the embodiments of the present disclosure in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present disclosure without making any creative efforts shall fall within the scope of protection of the present disclosure.

[0091] The term "comprise" and any variations thereof in the specification and claims of the present disclosure are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to the process, method, product, or apparatus. In addition, the use of "and / or" in the specification and claims to indicate at least one of the connected objects, such as A and / or B, means that A alone, B alone, and both A and B are included.

[0092] In the embodiments of the present disclosure, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present disclosure should not be construed as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0093] In order to better understand the embodiments of the present disclosure, the following technical terms are first introduced.

[0094] (1) SBFD subband

[0095] An SBFD subband consists of a set of consecutive resource blocks (RBs) with the same transmission direction. An SBFD subband includes one or more RBs. An SBFD subband with uplink transmission direction is called an SBFD-UL subband, and an SBFD subband with downlink transmission direction is called an SBFD-DL subband.

[0096] (2) Guard subband.

[0097] The Guard subband includes one or more RBs between adjacent SBFD-UL subband and SBFD-DL subband, and is not used for uplink transmission or downlink transmission.

[0098] (3)SBFD symbol or slot

[0099] An SBFD symbol or time slot is defined as a symbol or time slot to which an SBFD subband is configured, or is defined as a symbol or time slot to which an SBFD subband is configured and which is to be used for SBFD operation, or is defined as a symbol or time slot used for SBFD operation.

[0100] (4) Non-SBFD symbols or time slots

[0101] Non-SBFD symbols or time slots are defined as symbols or time slots for which no SBFD subband is configured, or as symbols or time slots that include symbols or time slots for which no SBFD subband is configured and symbols or time slots that are configured with SBFD subband but will not be used for SBFD operation, or as symbols or time slots that are not used for SBFD operation.

[0102] (5)CSI subband.

[0103] A CSI subband is defined as a subband used for CSI feedback. Its specific definition can be found in the relevant description in existing protocols. In existing protocols, the base station can configure one of two possible CSI subband sizes (subband sizes) for the UE through higher-layer signaling. The specific CSI subband size is determined by the number of RBs contained in the BWP and the base station's higher-layer signaling.

[0104] 2 , an embodiment of the present disclosure provides a communication processing method, which is applied to a terminal. The specific steps include: Step 201 .

[0105] Step 201: Receive a channel state information feedback configuration, where the number of bits corresponding to the CSI reporting bandwidth (CSI-ReportingBand) in the channel state information feedback configuration is less than or equal to the number of CSI subbands included in the bandwidth part (BWP), and each bit indicates a CSI subband, wherein the number of CSI subbands included in the BWP is determined at least based on the number of physical resource blocks in the BWP and the size of the CSI subband.

[0106] When the number of bits corresponding to the CSI-ReportingBand is less than the number of CSI subbands included in the BWP, the bits corresponding to the CSI-ReportingBand correspond one-to-one to some CSI subbands.

[0107] In one embodiment of the present disclosure, when the number of bits corresponding to the CSI-ReportingBand is less than the number of CSI subbands included in the BWP, the channel state information feedback configuration is used for CSI feedback corresponding to a situation where a physical downlink shared channel (PDSCH) is transmitted in a sub-band full-duplex (SBFD) time unit, and the method further includes:

[0108] Channel measurement is performed based on a first non-zero power channel state information reference signal (Non-Zero Power CSI-RS, NZP CSI-RS) opportunity in the SBFD time unit in the time domain, where the channel measurement is used to determine the CSI fed back at a first time (e.g., time slot n, the value of n is not limited), and the first NZP CSI-RS opportunity is no later than a reference resource (CSI reference resource) of the CSI.

[0109] It can be understood that the first time is used to represent the moment of feeding back the CSI.

[0110] In one embodiment of the present disclosure, when the number of bits corresponding to the CSI-ReportingBand is equal to the number of CSI subbands included in the BWP, the channel state information feedback configuration is used to determine (or assume) CSI feedback corresponding to a case where the PDSCH is transmitted in a non-subband full-duplex (non-SBFD) time unit, and the method further includes:

[0111] Based on the second NZP CSI-RS opportunity in the non-SBFD time unit in the time domain, channel measurements are performed, where the channel measurements are used to determine the CSI fed back at a second time (e.g., time slot n, the value of n is not limited), and the second NZP CSI-RS opportunity is no later than the reference resource of the CSI.

[0112] It can be understood that the second time is used to represent the moment of feeding back the CSI.

[0113] In one embodiment of the present disclosure, when the number of bits corresponding to the CSI reporting bandwidth is equal to the number of CSI subbands included in the BWP, the channel state information feedback configuration further includes first information;

[0114] The first information is used to indicate whether the channel state information feedback configuration is used to determine both the CSI feedback corresponding to the case where PDSCH is transmitted in an SBFD time unit and the CSI feedback corresponding to the case where PDSCH is transmitted in a non-SBFD time unit.

[0115] In one embodiment of the present disclosure, if the first information (for example, the first information may be bit "0" or "disable") indicates that the channel state information feedback configuration does not enable both the function of determining CSI feedback corresponding to a case where the PDSCH is transmitted in an SBFD time unit and the function of determining CSI feedback corresponding to a case where the PDSCH is transmitted in a non-SBFD time unit, or if the channel state information feedback configuration does not include the first information, the channel state information feedback configuration is used to determine CSI feedback corresponding to a case where the PDSCH is transmitted in a non-SBFD time unit;

[0116] The method further comprises:

[0117] Based on the third NZP CSI-RS opportunity in the non-SBFD time unit in the time domain, channel measurement is performed, where the channel measurement is used to determine the CSI fed back at a third time (e.g., time slot n, the value of n is not limited), and the third NZP CSI-RS opportunity is no later than the reference resource of the CSI.

[0118] It can be understood that the third time is used to indicate the moment of feeding back CSI.

[0119] In one embodiment of the present disclosure, if the first information (for example, the first information may be bit "1" or "enable") 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 channel measurement restriction in the time domain in the channel state information feedback configuration is set to configured, the method further includes:

[0120] Based on the most recent fourth NZP CSI-RS opportunity, channel measurement is performed, where the channel measurement is used to determine the CSI fed back at a fourth time (e.g., time slot n, the value of n is not limited), the most recent fourth NZP CSI-RS opportunity is no later than the reference resource of the CSI, and the most recent fourth NZP CSI-RS opportunity is within the non-SBFD time unit in the time domain, or within the SBFD time unit.

[0121] It is understandable that the fourth time is used to indicate the moment of feeding back the CSI. The first time, second time, third time and fourth time may be the same or different, and are not specifically limited in this embodiment.

[0122] In one embodiment of the present disclosure, the method further comprises:

[0123] When the fourth most recent NZP CSI-RS opportunity (i.e., the most recent NZP CSI-RS opportunity) is within the non-SBFD time unit in the time domain, determining, according to a value of the first bit, whether to feed back CSI associated with each bit in the first bits;

[0124] or,

[0125] When the most recent fourth NZP CSI-RS opportunity is within the SBFD time unit in the time domain, not feeding back the CSI associated with the first bit, or feeding back a specific CSI value as the CSI associated with the first bit;

[0126] The first bit includes M bits corresponding to the M original CSI subbands in the second bit;

[0127] The second bit is X bits corresponding to the CSI-ReportingBand in the channel state information feedback configuration;

[0128] The M original CSI subbands are used to represent the M complete CSI subbands among the N CSI subbands included in the BWP and completely included in the subband full-duplex uplink subband SBFD-UL subband in the frequency domain, or included in the SBFD-UL subband and the guard subband;

[0129] Wherein, M, X, and N are all integers greater than or equal to 1.

[0130] In one embodiment of the present disclosure, the method further comprises:

[0131] The number of bits of the fed-back CSI is determined according to the value of the first bit.

[0132] In one embodiment of the present disclosure, the method further comprises:

[0133] Sending second information, where the second information is used to indicate whether the terminal supports using a channel state information feedback configuration for both determining CSI feedback corresponding to a situation where PDSCH is transmitted in an SBFD time unit and determining CSI feedback corresponding to a situation where PDSCH is transmitted in a non-SBFD time unit.

[0134] The embodiments of the present disclosure can meet the channel state information feedback requirements 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.

[0135] 3 , an embodiment of the present disclosure provides a communication processing method, which is applied to a network-side device. The specific steps include: Step 301 .

[0136] Step 301: Send a channel state information feedback configuration, where the number of bits corresponding to the CSI reporting bandwidth CSI-ReportingBand in the channel state information feedback configuration is less than or equal to the number of CSI subbands included in the BWP, and each bit indicates a CSI subband, wherein the number of CSI subbands included in the BWP is determined at least according to the number of physical resource blocks of the BWP and the size of the CSI subband.

[0137] In one embodiment of the present disclosure, when the number of bits corresponding to the CSI-ReportingBand is less than the number of CSI subbands included in the BWP, 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.

[0138] In one embodiment of the present disclosure, when the number of bits corresponding to the CSI-ReportingBand is equal to the number of CSI subbands included in the BWP, 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.

[0139] In one embodiment of the present disclosure, when the number of bits corresponding to the CSI reporting bandwidth is equal to the number of CSI subbands included in the BWP, the channel state information feedback configuration further includes first information;

[0140] The first information is used to indicate whether the channel state information feedback configuration is used to determine both the CSI feedback corresponding to the case where PDSCH is transmitted in an SBFD time unit and the CSI feedback corresponding to the case where PDSCH is transmitted in a non-SBFD time unit.

[0141] In one embodiment of the present disclosure, if the first information indicates that the channel state information feedback configuration does not enable the function of determining the CSI feedback corresponding to the situation where PDSCH is transmitted in the SBFD time unit, and determining the CSI feedback corresponding to the situation where PDSCH is transmitted in the non-SBFD time unit, or if the channel state information feedback configuration does not include the first information, then the channel state information feedback configuration is used to determine the CSI feedback corresponding to the situation where PDSCH is transmitted in the non-SBFD time unit.

[0142] In one embodiment of the present disclosure, if the first information indicates that the channel state information feedback configuration is used both to determine the CSI feedback corresponding to the situation where PDSCH is transmitted in an SBFD time unit and to determine the CSI feedback corresponding to the situation where PDSCH is transmitted in a non-SBFD time unit, the time domain restriction of the channel measurement in the channel state information feedback configuration is set to configured.

[0143] In one embodiment of the present disclosure, the method further comprises:

[0144] Receive second information, where the second information is used to indicate whether the terminal supports configuring a channel state information feedback to determine both the CSI feedback corresponding to a situation where PDSCH is transmitted in an SBFD time unit and the CSI feedback corresponding to a situation where PDSCH is transmitted in a non-SBFD time unit.

[0145] The embodiments of the present disclosure can meet the channel state information feedback requirements 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.

[0146] 4 , an embodiment of the present disclosure provides a communication processing method, which is applied to a terminal. The specific steps include: Step 401 .

[0147] Step 401: Receive third information, where the third information is used to indicate that the channel state information feedback configuration is used for at least one of the following: (1) for determining CSI feedback corresponding to a situation where PDSCH is transmitted in an SBFD time unit; or, (2) for determining CSI feedback corresponding to a situation where PDSCH is transmitted in a non-SBFD time unit; or, (3) for determining CSI feedback corresponding to a situation where PDSCH is transmitted in an SBFD time unit, and can be used to determine CSI feedback corresponding to a situation where PDSCH is transmitted in a non-SBFD time unit.

[0148] In one 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 CSI feedback corresponding to a situation where the PDSCH is transmitted in an SBFD time unit, and the method further includes:

[0149] Based on the fifth NZP CSI-RS opportunity in the SBFD time unit in the time domain, channel measurement is performed, where the channel measurement is used to determine the CSI fed back at the fifth time (e.g., 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.

[0150] The fifth time is used to indicate the time of feeding back CSI.

[0151] In one 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 CSI feedback corresponding to a situation where the PDSCH is transmitted in a non-SBFD time unit, and the method further includes:

[0152] Based on the sixth NZP CSI-RS opportunity in the non-SBFD time unit in the time domain, channel measurement is performed, where the channel measurement is used to determine the CSI fed back at a sixth time (e.g., 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.

[0153] The sixth time is used to indicate the time of feeding back CSI.

[0154] In one 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 CSI feedback corresponding to a case where the PDSCH is transmitted in an SBFD time unit and CSI feedback corresponding to a case where the PDSCH is transmitted in a non-SBFD time unit, and the limitation of channel measurement in the time domain in the channel state information feedback configuration is set to configured. The method further includes:

[0155] Based on the most recent seventh NZP CSI-RS opportunity, channel measurement is performed, where 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 within the SBFD time unit.

[0156] The seventh time is used to indicate the time of feeding back CSI.

[0157] It can be understood that the fifth time, the sixth time and the seventh time may be the same or different.

[0158] In one embodiment of the present disclosure, when the most recent seventh NZP CSI-RS opportunity is within the SBFD time unit in the time domain, the method further includes:

[0159] Not feeding back the CSI associated with the target bit, or feeding back a specific CSI value as the CSI associated with the target bit;

[0160] The target bits include: one or more bits corresponding to multiple CSI subbands completely included in the SBFD-UL subband in the frequency domain, among the bits corresponding to the CSI-ReportingBand in the channel state information feedback configuration.

[0161] For example, if the most recent seventh NZP CSI-RS opportunity is within SBFD symbols or slots in the time domain, the UE ignores the values ​​of several target bits corresponding to several CSI subbands that are 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 value as the CSI associated with the target bit for feedback.

[0162] The embodiments of the present disclosure can meet the channel state information feedback requirements 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.

[0163] 5 , an embodiment of the present disclosure provides a communication processing method, which is applied to a network-side device. The specific steps include: Step 501 .

[0164] Step 501: Send third information, where the third information is used to indicate that the channel state information feedback configuration is used for at least one of the following: (1) for determining the CSI feedback corresponding to the situation where PDSCH is transmitted in the SBFD time unit; or, (2) for determining the CSI feedback corresponding to the situation where PDSCH is transmitted in the non-SBFD time unit; or, (3) for determining 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.

[0165] In an embodiment 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 where the PDSCH is transmitted in an SBFD time unit.

[0166] 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 CSI feedback corresponding to a situation where the PDSCH is transmitted in a non-SBFD time unit.

[0167] 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 the SBFD time unit and the CSI feedback corresponding to the situation where PDSCH is transmitted in the non-SBFD time unit, and the channel measurement restriction in the time domain in the channel state information feedback configuration is set to configured.

[0168] The embodiments of the present disclosure can meet the channel state information feedback requirements 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.

[0169] To facilitate understanding of the following embodiments (Examples 1 to 9), the meanings of terms such as "X bits," "N original CSI subbands," "M original CSI subbands," "L original CSI subbands," "NM original CSI subbands," and "NML original CSI subbands" are first introduced.

[0170] (1) “X bits”: defined as the X bits corresponding to the CSI-ReportingBand in the channel state information feedback configuration (CSI-ReportConfig) configured by the base station for the terminal.

[0171] (2) “N original CSI subbands”: defined as the N CSI subbands contained in the BWP.

[0172] (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 the SBFD-UL subband and Guard subbands, if there are Guard subbands) in the frequency domain.

[0173] (4) “L original CSI subbands”: defined as the L CSI subbands among the N CSI subbands included in the BWP that partially overlap with the SBFD-DL subbands in the frequency domain (i.e., each CSI subband in the L CSI subbands partially overlaps with the SBFD-DL subband in the frequency domain and partially overlaps with the SBFD-UL subband and / or Guard subband).

[0174] (5) “NM original CSI subbands”: defined as the NM CSI subbands that belong to the N CSI subbands included in the BWP and do not belong to the “M original CSI subbands”.

[0175] (6) “NML CSI subbands”: defined as the NML 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”.

[0176] Example 1:

[0177] 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 CSI subband in the M CSI subbands is completely located in 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 CSI subband in the L CSI subbands has a portion overlapping with the SBFD-DL subband in the frequency domain, and another portion overlapping with the SBFD-UL subband and / or Guard subband in the frequency domain), then X can be NM or NML.

[0178] Example 2:

[0179] Assuming M > 0 and L > 0, when X = NM (i.e., when the csi-ReportingBand in the CSI-ReportConfig configured by the base station for the terminal corresponds to NM bits), the "X bits" indicate NM redefined CSI subbands (there is a one-to-one correspondence between the X bits and the NM redefined CSI subbands). The NM redefined CSI subbands include the "NML original CSI subbands" and the L redefined CSI subbands that are the result of redefining the "L original CSI subbands."

[0180] The method for redefining “L original CSI subbands” is:

[0181] For the L original CSI subbands, only the parts overlapping with the SBFD-DL subbands are retained in the frequency domain, thus obtaining L redefined CSI subbands. The order in which the NM redefined CSI subbands correspond one-to-one to the X bits is consistent with the order in which they are arranged 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 the 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 / slots in the time domain, and the NZP CSI-RS timing is no later than the CSI reference resource.

[0182] Example of Example 2:

[0183] Taking BWP = 275 PRBs, 2 SBFD-DL subbands (111 PRBs and 110 PRBs), 1 SBFD-DL subband (50 PRBs), 2 Guard subbands (2 PRBs each), and CSI subband size = 32 PRBs as an example, the number of original CSI subbands included in the BWP and their numbering are shown in Figure 6. Among them, BWP = 275 PRBs, 2 SBFD-DL subbands (111 PRBs and 110 PRBs), 1 SBFD-UL subband (50 PRBs), 2 Guard subbands (2 PRBs each), CSI subband size = 32 PRBs, and the BWP contains 9 original CSI subbands, N = 9, M = 1, and L = 2.

[0184] When X=NM=8 (i.e., when the base station configures 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 "NML 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 redefining the "L original CSI subbands" (i.e., {CSI subband#4, CSI subband#6}). The L original CSI subbands (i.e., {CSI subband #4, CSI subband #6}) are redefined by retaining only the frequency-domain overlap between CSI subband #4 and CSI subband #6 and the SBFD-DL subbands as the redefined CSI subbands. Figure 7 shows the NM redefined CSI subbands indicated by "X bits" (redefined CSI subbands are denoted by "CSI subband #i'"). Among them, NM 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 subband#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.

[0185] Example 3:

[0186] Assuming M > 0 and L > 0, when X = NML (i.e., when the csi-ReportingBand in the CSI-ReportConfig configured by the base station for the terminal corresponds to NML bits), "X bits" indicate NML redefined CSI subbands (there is a one-to-one correspondence between X bits and NML redefined CSI subbands), and the NML redefined CSI subbands are the "NML original CSI subbands." The order of the NML redefined CSI subbands in their one-to-one correspondence with the X bits is consistent with their order in the BWP.

[0187] The base station and UE understand this CSI-ReportConfig as being used only to determine CSI feedback for the case where PDSCH is transmitted in an SBFD slot. In this case, the UE's channel measurements for calculating the CSI feedback at slot n are based only on NZP CSI-RS opportunities that fall within the SBFD symbols or slots in the time domain and are no later than the CSI reference resource.

[0188] Example of embodiment 3: Based on the situation shown in FIG6 ,

[0189] When X=NML=6 (i.e., when the base station configures 6 bits corresponding to the csi-ReportingBand in the CSI-ReportConfig for the terminal), "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-to-one.

[0190] Example 4:

[0191] 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), 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). The N redefined CSI subbands are the "N original CSI subbands." The order of the N redefined CSI subbands in their one-to-one correspondence with the X bits is consistent with their order in the BWP.

[0192] The base station and UE understand this CSI-ReportConfig as being used only to determine CSI feedback for the case where PDSCH is transmitted in a non-SBFD slot. In this case, the UE's channel measurements for calculating the CSI feedback at slot n are based only on NZP CSI-RS opportunities that fall within non-SBFD symbols / slots in the time domain and are no later than the CSI reference resource.

[0193] Example 5:

[0194] Assuming M>0 and L>0, when X=N (that is, 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 (for example, a 1-bit indication) whether 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 an SBFD slot".

[0195] If the base station instructs the UE through signaling (for example, bit '0') that the CSI-ReportConfig is not enabled to dynamically be 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 by default, the CSI-ReportConfig is only used for "determining the CSI feedback corresponding to the case 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 opportunity in the non-SBFD symbols or slots in the time domain, and the NZP CSI-RS opportunity is no later than the CSI reference resource.

[0196] 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 the 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 occasion, and the NZP CSI-RS occasion is no later than the CSI reference resource.

[0197] If the most recent NZP CSI-RS opportunity falls within a non-SBFD symbol or slot in the time domain, the N redefined CSI subbands are the "N original CSI subbands." In this case, the UE cannot ignore the values ​​of the M bits corresponding to the "M original CSI subbands" out of the X bits. The UE needs to determine whether to feedback the associated CSI based on the values ​​of these M bits.

[0198] If the most recent NZP CSI-RS opportunity is within SBFD symbols or slots in the time domain, the N redefined CSI subbands include "NML original CSI subbands", "M original CSI subbands", and L redefined CSI subbands after redefining the "L original CSI subbands". The method of redefining the "L original CSI subbands" is to retain only the parts of the L original CSI subbands that overlap with the SBFD-DL subbands in the frequency domain, that is, to obtain L redefined CSI subbands. 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 the 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.

[0199] 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, the values ​​of the M bits corresponding to the "M original CSI subbands" out of the X bits need to be considered (i.e., they cannot be ignored) when determining the number of bits occupied by the CSI fed back by the UE.

[0200] Optionally, the UE may report a terminal capability indication, which is used to indicate to 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".

[0201] Example 6:

[0202] Assuming M>0 and L=0, when X=NM (i.e., when the csi-ReportingBand in the CSI-ReportConfig configured by the base station for the terminal corresponds to NM bits), similar to the above embodiment 2, "X bits" indicate NM redefined CSI subbands (there is a one-to-one correspondence between the X bits and the NM redefined CSI subbands), and the NM redefined CSI subbands are the "NM original CSI subbands." However, in this case, the "L original CSI subbands" and the L bits associated therewith do not exist. Therefore, the content related to these L bits in the above embodiment 2 is not applicable. The description and understanding of the rest of embodiment 2 are applicable.

[0203] Example 7:

[0204] 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), 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, in this case, there are no "L original CSI subbands" and the L bits associated therewith. Therefore, 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.

[0205] Example 8:

[0206] 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), 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, in this case, the "M original CSI subbands" and the M bits associated therewith do not exist in the X bits. Therefore, 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.

[0207] Example 9:

[0208] Assuming M=0 and L>0, when X=NL (that is, when the csi-ReportingBand in the CSI-ReportConfig configured by the base station for the terminal corresponds to NL bits), "X bits" indicate NL redefined CSI subbands (there is a one-to-one correspondence between X bits and NL redefined CSI subbands), and the NL redefined CSI subbands are "the NML original CSI subbands". The order in which the NL redefined CSI subbands correspond one-to-one to the X bits is consistent with the order in which they are arranged in the BWP. The base station and UE understand this CSI-ReportConfig as follows: this 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 within the SBFD symbols / slots in the time domain, and the NZP CSI-RS timing is not later than the CSI reference resource.
