[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to Chinese Patent Application No. 202410382962.1 filed in China on March 29, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0003] The present disclosure relates to the field of wireless communications, and in particular to an information indication method, apparatus, related equipment, storage medium, and computer program product. Background Art

[0004] In related technologies, a base station uses time-division multiplexing (TDM) on a time division duplexing (TDD) carrier to perform uplink and downlink multiplexing transmission. However, due to the limited uplink duty cycle, the uplink coverage performance, uplink and downlink latency of the user equipment (UE) are all limited by the TDD uplink and downlink configurations. Based on this, the subband non-overlapping full duplex (SBFD) technology is proposed. The basic idea of ​​this technology is to configure a part of the time slot (slot) or symbol (symbol) as an SBFD slot or symbol, that is, to use part of the frequency resources of the bandwidth part (BWP) as the uplink subband (SBFD-UL subband) of SBFD, and the other part of the frequency resources as the downlink subband (SBFD-DL subband) of SBFD. As shown in Figure 1, when the base station transmits on an SBFD symbol, the base station can simultaneously transmit downlink on the SBFD-DL subband and receive uplink on the SBFD-UL subband, thereby achieving simultaneous uplink and downlink transmission and reception on the base station side.

[0005] However, when a communication system supports SBFD operation, there is no effective solution for how to perform operations associated with downlink channel state information (CSI). Summary of the Invention

[0158] SBFD subband: A group of contiguous resource blocks (RBs) used for the same transmission direction. Specifically, it may include one or more RBs (when multiple RBs are included, the RBs are contiguous and used for the same transmission direction). An SBFD subband with uplink transmission is called an SBFD-UL subband, and an SBFD subband with downlink transmission is called an SBFD-DL subband.

[0159] SBFD symbol or slot (also referred to as SBFD symbol / slot): defined as a symbol or slot configured with SBFD subband(s), or defined as a symbol / slot configured with SBFD subband(s) and to be used for SBFD operation, or defined as a symbol or slot used for SBFD operation;

[0160] Non-SBFD symbol or slot (also referred to as Non-SBFD symbol / slot): defined as a symbol or slot that is not configured with SBFD subband(s), or defined as including a symbol or slot that is not configured with SBFD subband(s) and a symbol or slot that is configured with SBFD subband(s) but will not be used for SBFD operation, or defined as a symbol or slot that is not used for SBFD operation;

[0161] CSI subband: Defined as the subband used for CSI feedback. The specific definition can be understood by referring to the relevant technical reference. In actual application, the base station can configure one of two possible CSI subband sizes for the UE through high-layer signaling. The specific CSI subband size can be determined based on the number of RBs contained in the BWP and the high-layer signaling of the base station.

[0162] In the related art, the CSI feedback method for TDD is designed for downlink use of all frequency resources (also called frequency domain resources) within the BWP. However, when a communication system supports SBFD operation, some frequency resources are used as the SBFD-UL subband for SBFD, while other frequency resources are used as the SBFD-DL subband for SBFD. Therefore, the CSI feedback method in the related art cannot be directly used in communication systems that support SBFD operation.

[0163] Based on this, in various embodiments of the present disclosure, the network side sends indication information of the time unit associated with sending SBFD CSI-RS to the terminal, so that the terminal can determine the time of CSI-RS measurement (which can also be understood as being able to determine the time of sending CSI-RS), so that it can perform measurements according to the determined time of CSI-RS measurement, and then perform CSI feedback, thereby improving the accuracy and effectiveness of downlink CSI feedback, thereby improving the downlink performance of the communication system.

[0164] The present disclosure provides an information indication method, which is applied to a terminal. As shown in FIG2 , the method includes:

[0165] Step 201: Receive first information, where the first information is used to instruct a terminal to measure a CSI-RS in one or more of the following time units:

[0166] a first time unit, the first time unit being associated with the SBFD;

[0167] A second time unit is not associated with SBFD.

[0168] In actual application, the terminal may be referred to as a UE or a user, etc. The embodiment of the present disclosure does not limit the name of the terminal, as long as its function is realized.

[0169] Since the terminal has received the first information, the first information is specifically used to instruct the terminal to measure the CSI-RS in the following one or more time units.

[0170] In actual application, the time unit may specifically include a slot or a symbol, etc.; this is not limited in the embodiments of the present disclosure. In a communication system that supports SBFD operation, the network configures CSI-RS for the terminal, and the network device (specifically, a base station, such as the next generation base station (the next Generation Node B, gNB)) sends the first information to the terminal to indicate in which time units the network device sends CSI-RS. Exemplarily, the first information may indicate that the CSI-RS is only sent in the SBFD symbol or slot (i.e., the first time unit), or indicate that the CSI-RS is only sent in the non-SBFD symbol / slot (i.e., the second time unit), or indicate that the CSI-RS is sent in both the SBFD symbol or slot and the non-SBFD symbol or slot.

[0171] In step 201, the terminal can receive the first information sent by the network device (specifically, it can be a base station); specifically, the network device can send the first information to the terminal through signaling such as Radio Resource Control (RRC) signaling, Media Access Control Control Element (MAC CE) or Downlink Control Information (DCI), that is, the terminal receives signaling such as RRC signaling, MAC CE or DCI, and the RRC signaling, MAC CE or DCI signaling contains the first information.

[0172] In actual application, as needed, the terminal may be instructed (also understood as configured) in which time units to send the CSI-RS according to different granularities of the configuration information of the CSI-RS resource.

[0173] Based on this, in one embodiment, the first information is configured for a CSI-ResourceConfig (which may include one or more CSI-RS resource sets (CSI Resource Sets), which may be NZP-CSI-RS-Resource Sets), that is, the indication or configuration of the first information is for each CSI-ResourceConfig (expressed as per CSI-ResourceConfig in English), that is, each CSI-ResourceConfig corresponds to one first information.

[0174] The first information may also be configured for an NZP-CSI-RS-Resource Set (which may include one or more NZP-CSI-RS-Resource), that is, the indication or configuration of the first information is for each NZP-CSI-RS-Resource Set (expressed as per NZP-CSI-RS-ResourceSet in English), that is, each NZP-CSI-RS-Resource Set corresponds to one first information.

[0175] The first information may also be configured for one NZP-CSI-RS-Resource, that is, the indication or configuration of the first information is for each NZP-CSI-RS-Resource (expressed as per NZP-CSI-RS-Resource in English), that is, each NZP-CSI-RS-Resource corresponds to one first information.

[0176] In actual application, the types of CSI-RS include: periodic CSI-RS (also called periodic CSI-RS), semi-persistent CSI-RS and aperiodic CSI-RS (also called aperiodic CSI-RS). Therefore, for different types of CSI-RS, it is necessary to combine the first information to specifically determine the sending time of this type of CSI-RS.

[0177] Based on this, in one embodiment, as shown in FIG2 , the method may further include:

[0178] Step 202: Determine the CSI-RS transmission time.

[0179] Since the CSI-RS is sent by the network device, from the perspective of the terminal, step 202 can also be understood as determining the reception time of the CSI-RS, that is, determining the measurement time of the CSI-RS.

[0180] Specifically, for periodic or semi-persistent CSI-RS, when the first information is used to indicate that CSI-RS is sent in the first time unit, that is, when the first information is used to indicate that the terminal measures CSI-RS in the first time unit, when the periodic CSI-RS or semi-persistent CSI-RS is located in the first time unit, the terminal measures the periodic CSI-RS or semi-persistent CSI-RS within the first time unit, or, when the periodic CSI-RS or semi-persistent CSI-RS is located in the second time unit, the terminal does not measure the periodic CSI-RS or semi-persistent CSI-RS within the second time unit.

[0181] Among them, from the perspective of transmission on the network side, for periodic or semi-persistent CSI-RS, when the first information is used to indicate the transmission of CSI-RS in the first time unit, that is, when the first information is used to indicate the transmission of CSI-RS in the first time unit, the first transmission opportunity of the periodic CSI-RS or semi-persistent CSI-RS is located in the first time unit, it is determined that the periodic CSI-RS or semi-persistent CSI-RS at the first transmission opportunity is sent, or, when the first transmission opportunity of the periodic CSI-RS or semi-persistent CSI-RS is located in the second time unit, it is determined that the periodic CSI-RS or semi-persistent CSI-RS at the first transmission opportunity is not sent.

[0182] From the perspective of terminal reception, when the first receiving opportunity corresponding to the first sending opportunity of the periodic CSI-RS or semi-persistent CSI-RS is located in the first time unit, it is determined that the periodic CSI-RS or semi-persistent CSI-RS at the first receiving opportunity is received; when the first receiving opportunity of the periodic CSI-RS or semi-persistent CSI-RS is located in the second time unit, it is determined that the periodic CSI-RS or semi-persistent CSI-RS at the first receiving opportunity is not received.

[0183] As can be seen from the above description, a periodic or semi-persistent CSI-RS is only transmitted in the first time unit. This means that for a CSI-RS transmission opportunity (i.e., a CSI-RS reception opportunity is determined, which can also be understood as a CSI-RS measurement opportunity) determined based on the configuration information of the CSI-RS, if the transmission opportunity is in the first time unit (correspondingly, the reception opportunity is also in the first time unit), the terminal assumes that the CSI-RS is normally transmitted at the transmission opportunity (i.e., the CSI-RS is normally received at the reception opportunity); if the transmission opportunity is in the second time unit (correspondingly, the reception opportunity is also in the second time unit), the terminal assumes that the CSI-RS is not transmitted at the transmission opportunity (further, the terminal does not use the resource elements corresponding to the CSI-RS at the transmission opportunity for rate matching (i.e., for transmitting the PDSCH)) of the Physical Downlink Shared Channel (i.e., for transmitting the PDSCH)) (i.e., the CSI-RS is not received at the reception opportunity).

[0184] For periodic or semi-persistent CSI-RS, when the first information is used to indicate that CSI-RS is sent in the second time unit, that is, when the first information is used to instruct the terminal to measure CSI-RS in the second time unit, when the periodic CSI-RS or semi-persistent CSI-RS is located in the second time unit, the terminal measures the periodic CSI-RS or semi-persistent CSI-RS in the second time unit, or, when the periodic CSI-RS or semi-persistent CSI-RS is located in the first time unit, the terminal does not measure the periodic CSI-RS or semi-persistent CSI-RS within the first time unit.

[0185] Among them, from the perspective of transmission on the network side, for periodic or semi-persistent CSI-RS, when the first information is used to indicate the transmission of CSI-RS in the second time unit, that is, when the first information is used to indicate the transmission of CSI-RS in the second time unit, the second transmission opportunity of the periodic CSI-RS or semi-persistent CSI-RS is located in the second time unit, it is determined that the periodic CSI-RS or semi-persistent CSI-RS at the second transmission opportunity is sent; when the second transmission opportunity of the periodic CSI-RS or semi-persistent CSI-RS is located in the first time unit, it is determined that the periodic CSI-RS or semi-persistent CSI-RS at the second transmission opportunity is not sent.

[0186] From the perspective of terminal reception, when the second receiving opportunity corresponding to the second sending opportunity of the periodic CSI-RS or semi-persistent CSI-RS is located in the second time unit, it is determined that the periodic CSI-RS or semi-persistent CSI-RS at the second receiving opportunity is received, or, when the second receiving opportunity of the periodic CSI-RS or semi-persistent CSI-RS is located in the first time unit, it is determined that the periodic CSI-RS or semi-persistent CSI-RS at the second receiving opportunity is not received.

[0187] From the above description, it can be seen that the periodic or semi-persistent CSI-RS is only sent in the second time unit, which means: for a CSI-RS transmission timing determined according to the configuration information of the CSI-RS (that is, determining a CSI-RS reception timing, which can also be understood as determining a CSI-RS measurement timing), if the transmission timing is located in the second time unit (correspondingly, the reception timing is also located in the second time unit), the terminal assumes that the CSI-RS is normally transmitted at this timing (that is, the CSI-RS is normally received at this reception timing); if the transmission timing is located in the first time unit (correspondingly, the reception timing is also located in the first time unit), the terminal assumes that the CSI-RS is not transmitted at this timing (further, the terminal will not use the resource elements corresponding to the CSI-RS at the transmission timing for PDSCH rate matching (that is, the CSI-RS is not received at this reception timing).

[0188] For periodic or semi-persistent CSI-RS, when the first information is used to indicate that CSI-RS is sent in both the first time unit and the second time unit, that is, when the first information is used to indicate that the terminal measures CSI-RS in both the first time unit and the second time unit, when the periodic CSI-RS or semi-persistent CSI-RS is located in the first time unit or the second time unit, the terminal measures the periodic CSI-RS or semi-persistent CSI-RS within the first time unit or the second time unit.

[0189] Among them, from the perspective of transmission on the network side, for periodic or semi-persistent CSI-RS, when the first information is used to indicate the transmission of CSI-RS in the first time unit and the second time unit, that is, when the first information is used to indicate the transmission of CSI-RS in the first time unit and the second time unit, the third transmission opportunity of the periodic CSI-RS or semi-persistent CSI-RS is located in the first time unit or the second time unit, it is determined that the periodic CSI-RS or semi-persistent CSI-RS at the third transmission opportunity is sent.

[0190] From the perspective of terminal reception, when the third receiving opportunity corresponding to the third sending opportunity of the periodic CSI-RS or semi-persistent CSI-RS is located in the first time unit or the second time unit, it is determined that the periodic CSI-RS or semi-persistent CSI-RS at the third receiving opportunity is received.

[0191] As can be seen from the above description, periodic or semi-persistent CSI-RS is sent in both the first time unit and the second time unit. This means that for a CSI-RS transmission timing determined according to the configuration information of the CSI-RS (i.e., determining a CSI-RS reception timing, which can also be understood as determining a CSI-RS measurement timing), regardless of whether the transmission timing is in the first time unit or the second time unit, the terminal assumes that the CSI-RS is normally transmitted at that timing (i.e., the CSI-RS is normally received at that reception timing).

[0192] For the non-periodic CSI-RS, when the first information is used to indicate that the CSI-RS is sent in the first time unit, that is, when the first information is used to instruct the terminal to measure the CSI-RS in the first time unit, when the non-periodic CSI-RS is located in the first time unit, the terminal measures the non-periodic CSI-RS in the first time unit, or when the non-periodic CSI-RS is located in the second time unit, the terminal measures the non-periodic CSI-RS in the first first time unit after the second time unit.

[0193] Among them, from the perspective of transmission on the network side, for non-periodic CSI-RS, when the first information is used to indicate the transmission of CSI-RS in the first time unit, that is, when the first information is used to indicate the transmission of CSI-RS in the first time unit, the fourth time unit for sending the non-periodic CSI-RS is located in the first time unit, it is determined that the non-periodic CSI-RS is sent in the fourth time unit; when the fourth time unit of the non-periodic CSI-RS is located in the second time unit, it is determined that the non-periodic CSI-RS is sent in the first first time unit after the fourth time unit.

[0194] From the perspective of terminal reception, when the fourth time unit is located in the first time unit, it is determined that the non-periodic CSI-RS is received in the fourth time unit; when the fourth time unit is located in the second time unit, it is determined that the non-periodic CSI-RS is received in the first first time unit after the fourth time unit.

[0195] In actual applications, for aperiodic CSI-RS, the network sends a DCI to trigger aperiodic CSI-RS transmission and aperiodic CSI feedback. The interval between the Physical Downlink Control Channel (PDCCH) slot and the aperiodic CSI-RS transmission slot triggered by the PDCCH (i.e., the CSI-RS offset) is based on the aperiodic triggering offset (aperiodicTriggeringOffset) in the NZP-CSI-RS-Resource Set configured via RRC signaling. Assuming that the aperiodicTriggeringOffset in the NZP-CSI-RS-Resource Set to which the aperiodic CSI-RS belongs, configured via RRC signaling, is X (i.e., the offset is X slots), and the network sends DCI in slot 'n' to trigger the aperiodic CSI-RS transmission, the aperiodic CSI-RS is transmitted in slot 'n+X'. As can be seen from the above description, the aperiodic CSI-RS is only sent in the first time unit, which means: if slot'n+X' is an SBFD slot (or the symbols mapped to the aperiodic CSI-RS in slot'n+X' are SBFD symbols), then the aperiodic CSI-RS is sent in slot'n+X'; if slot'n+X' is a non-SBFD slot (or the symbols mapped to the aperiodic CSI-RS in slot'n+X' are non-SBFD symbols), then the aperiodic CSI-RS is not sent in slot'n+X', but is sent in the first SBFD slot after slot'n+X'.

[0196] For the non-periodic CSI-RS, when the first information is used to indicate that the CSI-RS is sent in the second time unit, that is, when the first information is used to instruct the terminal to measure the CSI-RS in the second time unit, when the non-periodic CSI-RS is located in the second time unit, the terminal measures the non-periodic CSI-RS in the second time unit, or when the non-periodic CSI-RS is located in the first time unit, the terminal measures the non-periodic CSI-RS in the first second time unit after the first time unit.

[0197] Among them, from the perspective of transmission on the network side, for non-periodic CSI-RS, when the first information is used to indicate the transmission of CSI-RS in the second time unit, that is, when the first information is used to indicate the transmission of CSI-RS in the second time unit, the fifth time unit for transmitting the non-periodic CSI-RS is located in the second time unit, it is determined that the non-periodic CSI-RS is transmitted in the fifth time unit; when the fifth time unit of the non-periodic CSI-RS is located in the first time unit, it is determined that the non-periodic CSI-RS is transmitted in the first second time unit after the fifth time unit.

[0198] From the perspective of terminal reception, when the receiving time unit corresponding to the fifth time unit is located in the second time unit, it is determined that the non-periodic CSI-RS is received in the receiving time unit corresponding to the fifth time unit; when the receiving time unit corresponding to the fifth time unit is located in the first time unit, it is determined that the non-periodic CSI-RS is received in the first second time unit after the receiving time unit corresponding to the fifth time unit.

[0199] As can be seen from the above description, the non-periodic CSI-RS is only sent in the second time unit, which means: if slot'n+X' is a non-SBFD slot (or the symbols mapped to the non-periodic CSI-RS in slot'n+X' are non-SBFD symbols), then the non-periodic CSI-RS is sent in slot'n+X'; if slot'n+X' is an SBFD slot (or the symbols mapped to the non-periodic CSI-RS in slot'n+X' are SBFD symbols), then the non-periodic CSI-RS is not sent in slot'n+X', but is sent in the first non-SBFD slot after slot'n+X'.

[0200] For non-periodic CSI-RS, when the first information is used to indicate that the CSI-RS is sent in the first time unit and the second time unit, that is, when the first information is used to indicate that the terminal measures the CSI-RS in both the first time unit and the second time unit, when the non-periodic CSI-RS is located in the first time unit or the second time unit, the terminal measures the non-periodic CSI-RS within the first time unit or the second time unit.

[0201] Among them, from the perspective of transmission on the network side, for non-periodic CSI-RS, when the first information is used to indicate the transmission of CSI-RS in the first time unit and the second time unit, that is, when the first information is used to indicate the transmission of CSI-RS in the first time unit and the second time unit, the sixth time unit for transmitting the non-periodic CSI-RS is located in the first time unit or the second time unit, it is determined that the non-periodic CSI-RS is transmitted in the sixth time unit.

[0202] From the perspective of terminal reception, when the sixth time unit is located in the first time unit or the second time unit, it is determined that the aperiodic CSI-RS is received in the receiving time unit corresponding to the sixth time unit.

[0203] As can be seen from the above description, the non-periodic CSI-RS will be sent in both the first time unit and the second time unit, which means that no matter slot'n+X' is an SBFD slot (or the symbols corresponding to the non-periodic CSI-RS mapping in slot'n+X' are SBFD symbols) or a non-SBFD slot (or the symbols corresponding to the non-periodic CSI-RS mapping in slot'n+X' are non-SBFD symbols), the non-periodic CSI-RS is sent in slot'n+X'.

[0204] In actual applications, when the communication system supports SBFD operation, the network can also allow the terminal to feedback the required CSI, further improving the accuracy and effectiveness of downlink CSI feedback. Specifically, the network can configure the CSI configuration for the terminal.

[0205] Based on this, in one embodiment, the method may further include:

[0206] receiving second information, where the second information is used to indicate that a piece of CSI report configuration information or a piece of sub-CSI report configuration information is one of the following:

[0207] first CSI report configuration information or first sub-CSI report configuration information, where the first CSI report configuration information or the first sub-CSI report configuration information is associated only with a first CSI-RS, and the first CSI-RS is associated with a first time unit;

[0208] second CSI report configuration information or second sub-CSI report configuration information, where the second CSI report configuration information or the second sub-CSI report configuration information is associated only with a second CSI-RS, and the second CSI-RS is associated with a second time unit;

[0209] third CSI report configuration information or third sub-CSI report configuration information, where the third CSI report configuration information or sub-CSI report configuration information is associated with both a first CSI-RS and a second CSI-RS, where the first CSI-RS is associated with a first time unit, and the second CSI-RS is associated with a second time unit;

[0210] in,

[0211] The first time unit is associated with the SBFD;

[0212] The second time unit is not associated with SBFD.

[0213] In actual application, the network device can send the second information to the terminal through RRC signaling, MAC CE or DCI signaling, that is, the terminal receives RRC signaling, MAC CE or DCI signaling, and the RRC signaling, MAC CE or DCI signaling contains the second information.

[0214] Regarding the content indicated by the second information, in other words, the second information is used to indicate that the configured CSI reporting resources are used for one or more of the following CSI reports:

[0215] a first CSI report based on a first CSI-RS, wherein the first CSI-RS is associated with SBFD;

[0216] A second CSI report based on a second CSI-RS, wherein the second CSI-RS is not associated with SBFD;

[0217] The second information is for one CSI report configuration information (it can also be understood that the second information is configured for one CSI report configuration information), that is, the indication or configuration of the second information is for each CSI report configuration (CSI-ReportConfig) (which may include one or more sub-CSI report configurations (CSI-subReportConfig)), that is, each CSI-ReportConfig corresponds to one second information;

[0218] Specifically, the second information is used to indicate that one CSI report configuration information may be first CSI report configuration information, and the first CSI report configuration information is associated only with the first CSI-RS; or, the second information is used to indicate that one CSI report configuration information may be second CSI report configuration information, and the second CSI report configuration information is associated only with the second CSI-RS; or, the second information is used to indicate that one CSI report configuration information may be third CSI report configuration information, and the third CSI report configuration information is associated with both the first CSI-RS and the second CSI-RS; wherein, the first CSI-RS is associated with a first time unit, and the second CSI-RS is associated with a second time unit.

[0219] The second information may also be for a sub-CSI report configuration information included in a CSI report configuration information (it may also be understood that the second information is configured for a sub-CSI report configuration information), that is, the indication or configuration of the second information is each CSI-subReportConfig, that is, each CSI-subReportConfig corresponds to one second information.

[0220] Specifically, the second information is used to indicate that one sub-CSI report configuration information may be the first sub-CSI report configuration information, and the first sub-CSI report configuration information is associated only with the first CSI-RS; or, the second information is used to indicate that one sub-CSI report configuration information may be the second sub-CSI report configuration information, and the second sub-CSI report configuration information is associated only with the second CSI-RS; or, the second information is used to indicate that one sub-CSI report configuration information may be the third sub-CSI report configuration information, and the third sub-CSI report configuration information is associated with both the first CSI-RS and the second CSI-RS; wherein, the first CSI-RS is associated with the first time unit, and the second CSI-RS is associated with the second time unit.

[0221] It should be noted that CSI-subReportConfig may also be called other names, which is not limited in the embodiments of the present disclosure.

[0222] In actual application, when the second information is used to indicate that the resource of the configured CSI report is used for the first CSI report based on the first CSI-RS (that is, when the second information is used to indicate that a CSI report configuration information or a sub-CSI report configuration information is the first CSI report configuration information or the first sub-CSI report configuration information), it indicates that the CSI-ReportConfig or CSI-subReportConfig is only used to feedback the CSI corresponding to the SBFD symbol or slot, which means that the CSI-ReportConfig or CSI-subReportConfig is only used to feedback the CSI obtained based on the CSI-RS transmitted in the SBFD symbol or slot. It can also be understood that the CSI-ReportConfig is only used to feedback the CSI used to reflect the SBFD symbol / slot channel state. In this case, CSI-ReportConfig can be called SBFD CSI-ReportConfig; CSI-subReportConfig can be called SBFD CSI-subReportConfig.

[0223] Wherein, when the first CSI-RS is a periodic CSI-RS or a semi-persistent CSI-RS (i.e., when the first CSI-RS is a periodic CSI-RS or a semi-persistent CSI-RS), the terminal measures the periodic CSI-RS or the semi-persistent CSI-RS only in the first time unit. When the first CSI-RS is an aperiodic CSI-RS (i.e., when the first CSI-RS is an aperiodic CSI-RS), when the aperiodic CSI-RS is located in the first time unit, the terminal measures the aperiodic CSI-RS in the first time unit; or when the aperiodic CSI-RS is located in the second time unit, the terminal measures the aperiodic CSI-RS in the first first time unit after the second time unit.

[0224] When the second information is used to indicate that the resources of the configured CSI report are used for the second CSI report based on the second CSI-RS (that is, when the second information is used to indicate that a CSI report configuration information or a sub-CSI report configuration information is the second CSI report configuration information or the second sub-CSI report configuration information), it indicates that the CSI-ReportConfig or CSI-subReportConfig is only used to feedback the CSI corresponding to the Non-SBFD symbol or slot, which means that the CSI-ReportConfig or CSI-subReportConfig is only used to feedback the CSI obtained based on the CSI-RS transmitted in the Non-SBFD symbol or slot. It can also be understood that the CSI-ReportConfig is only used to feedback the CSI used to reflect the channel state of the Non-SBFD symbol / slot. In this case, the CSI-ReportConfig can be called the Non-SBFD CSI-ReportConfig; the CSI-subReportConfig can be called the Non-SBFD CSI-subReportConfig.

[0225] Wherein, when the second CSI-RS is a periodic CSI-RS or a semi-persistent CSI-RS, the terminal measures the periodic CSI-RS or semi-persistent CSI-RS only in the second time unit. When the second CSI-RS is an aperiodic CSI-RS, when the aperiodic CSI-RS is located in the second time unit, the terminal measures the aperiodic CSI-RS in the second time unit; or when the aperiodic CSI-RS is located in the first time unit, the terminal measures the aperiodic CSI-RS in the first second time unit after the first time unit.

[0226] When the second information is used to indicate that the resources of the configured CSI report are used for the first CSI report based on the first CSI-RS and the second CSI report based on the second CSI-RS (that is, when the second information is used to indicate that a CSI report configuration information or a sub-CSI report configuration information is the third CSI report configuration information or the third sub-CSI report configuration information), it indicates that the CSI-ReportConfig or CSI-subReportConfig is used to feedback the CSI corresponding to the SBFD symbol or slot and the CSI corresponding to the non-SBFD symbol or slot. This means that the CSI-ReportConfig or CSI-subReportConfig is used to feedback the CSI obtained based on the CSI-RS transmitted in the SBFD symbol or slot and the CSI obtained based on the CSI-RS transmitted in the non-SBFD symbol or slot. It can also be understood that the CSI-ReportConfig or CSI-subReportConfig is used to feedback the CSI used to reflect the channel state of the SBFD symbol or slot and the CSI used to reflect the channel state of the non-SBFD symbol / slot. In this case, the CSI-ReportConfig may be referred to as SBFD&non-SBFD CSI-ReportConfig; and the CSI-subReportConfig may be referred to as SBFD&non-SBFD CSI-subReportConfig.

[0227] Wherein, when the first CSI-RS and the second CSI-RS are periodic CSI-RS or semi-persistent CSI-RS, the terminal measures the periodic CSI-RS or semi-persistent CSI-RS within the first time unit or the second time unit. When the first CSI-RS and the second CSI-RS are aperiodic CSI-RS, when the aperiodic CSI-RS is located within the first time unit or the second time unit, the terminal measures the aperiodic CSI-RS within the first time unit or the second time unit.

[0228] Here, the CSI report configuration information associated with SBFD can be associated only with the first CSI-RS (for channel measurement), or associated with both the first CSI-RS and the second CSI-RS; accordingly, the sub-CSI report configuration information associated with SBFD can be associated only with the first CSI-RS, or associated with both the first CSI-RS and the second CSI-RS.

[0229] Accordingly, the CSI report configuration information not associated with SBFD can be associated only with the second CSI-RS (for channel measurement), or associated with both the first CSI-RS and the second CSI-RS; accordingly, the sub-CSI report configuration information not associated with SBFD can be associated only with the second CSI-RS, or associated with both the first CSI-RS and the second CSI-RS.

[0230] After receiving the second information, the terminal feeds back CSI based on the first information and the second information.

[0231] Accordingly, an embodiment of the present disclosure further provides an information indication method, which is applied to a network device. As shown in FIG3 , the method includes:

[0232] Step 301: Send first information to a terminal, where the first information is used to indicate that a CSI-RS is to be sent in one or more of the following time units:

[0233] a first time unit, the first time unit being associated with the SBFD;

[0234] A second time unit is not associated with SBFD.

[0235] In actual application, the network device may first determine the first information as needed, and the embodiment of the present disclosure does not limit the specific process of determining the first information.

[0236] In one embodiment, as shown in FIG3 , the method may further include:

[0237] Step 302: Send second information to the terminal, where the second information is used to indicate that a CSI report configuration information or a sub-CSI report configuration information is one of the following:

[0238] first CSI report configuration information or first sub-CSI report configuration information, where the first CSI report configuration information or the first sub-CSI report configuration information is associated only with a first CSI-RS, and the first CSI-RS is associated with a first time unit;

[0239] second CSI report configuration information or second sub-CSI report configuration information, where the second CSI report configuration information or the second sub-CSI report configuration information is associated only with a second CSI-RS, and the second CSI-RS is associated with a second time unit;

[0241] in,

[0242] The first time unit is associated with the SBFD;

[0243] The second time unit is not associated with SBFD.

[0245] The present disclosure also provides an information indication method, as shown in FIG4 , which includes:

[0246] Step 401: A network device sends first information to a terminal, where the first information is used to indicate that a CSI-RS is to be sent in one or more of the following time units:

[0247] a first time unit, the first time unit being associated with the SBFD;

[0248] a second time unit, the second time unit not being associated with the SBFD;

[0249] Step 402: The terminal receives the first information.

[0250] Here, it should be noted that the specific processing procedures of the terminal and the network device have been described in detail above and will not be repeated here.

[0251] The information indication method provided by the embodiment of the present disclosure is that the network device sends first information to the terminal, and the first information is used to indicate the terminal to measure CSI-RS in one or more of the following time units: a first time unit, the first time unit is associated with SBFD; a second time unit, the second time unit is not associated with SBFD. The technical solution provided by the embodiment of the present disclosure is that the network side sends indication information of the time unit associated with sending SBFD CSI-RS to the terminal, so that the terminal can determine the time of CSI-RS measurement (which can also be understood as being able to determine the time of sending CSI-RS), so that it can perform measurements according to the determined time of CSI-RS measurement, and then perform CSI feedback, thereby improving the accuracy and effectiveness of downlink CSI feedback, and thus improving the downlink performance of the communication system. At the same time, the network device sends second information to the terminal, where the second information is used to indicate that a CSI report configuration information or a sub-CSI report configuration information is one of the following: first CSI report configuration information or first sub-CSI report configuration information, where the first CSI report configuration information or the first sub-CSI report configuration information is associated only with a first CSI-RS, which is associated with a first time unit; second CSI report configuration information or second sub-CSI report configuration information, where the second CSI report configuration information or the second sub-CSI report configuration information is associated only with a second CSI-RS, which is associated with a second time unit; or third CSI report configuration information or third sub-CSI report configuration information, where the third CSI report configuration information or the third sub-CSI report configuration information is associated with both the first CSI-RS and the second CSI-RS, where the first CSI-RS is associated with a first time unit, and the second CSI-RS is associated with a second time unit; wherein the first time unit is associated with SBFD, and the second time unit is not associated with SBFD. In this way, the network allows the terminal to feedback the required CSI, further improving the accuracy and effectiveness of downlink CSI feedback.

[0252] The present disclosure is further described in detail below with reference to application examples.
