Abstract

The invention discloses a communication method and device, terminal equipment and network equipment, and relates to the technical field of communication. As the number of receiving antennas of the receiver is increased, in order to ensure the low complexity of the receiver under the condition of a large number of receiving antennas, the receiver may be split into a plurality of sub-receivers, so that each sub-receiver has a small number of receiving antennas.

Thus, different sub-receivers perform CSI measurement according to respective measurement resources, and perform respective CSI reporting after the CSI measurement is completed, so that the different sub-receivers can correctly acquire and report respective channel information / CSI information, and a network can perform link adaptation and the like on the different sub-receivers according to the CSI reports of the different sub-receivers.

Description

Technical Field

[0001] This application relates to the field of communication technologies, and in particular, to a communication method and apparatus, a terminal device, and a network device. Background Art

[0002] The standard protocols specified by the 3rd Generation Partnership Project (3GPP) have introduced related research on channel state information (CSI). In the related research on CSI, the network can perform CSI-related configurations so that the terminal device can perform CSI measurements, CSI acquisition, and CSI reporting according to the CSI-related configurations.

[0003] Currently, in the related research on CSI, the terminal device is regarded as a receiver with receiving antennas. In this way, during CSI measurement, CSI acquisition, and CSI reporting, the receiver can perform CSI measurement on the downlink channel according to the measurement resources to obtain channel information / CSI information, and then report the channel information / CSI information to the network for link adaptation and the like.

[0004] However, as the number of receiving antennas of the receiver increases, in order to ensure that the receiver has low complexity under a large number of receiving antennas, the receiver may be split into multiple sub-receivers, so that each sub-receiver has a smaller number of receiving antennas and / or lower processing complexity. At this time, how to perform CSI-related configurations under multiple sub-receivers still needs further research. Summary of the Invention

[0005] This application provides a communication method and apparatus, a terminal device, and a network device, aiming to achieve CSI-related configurations under multiple sub-receivers and ensure that each sub-receiver can correctly obtain and report its own channel information / CSI information.

[0008] The terminal device receiving unit is one of a terminal device receiving antenna port group, a terminal device antenna panel, or a terminal device sub-receiver.

[0009] It can be seen that in this embodiment, the terminal device receiving unit corresponding to the CSI report can be determined, such that different CSI reports can have their respective corresponding terminal device receiving units, or such that different terminal device receiving units can have their respective corresponding CSI reports. At the same time, since the CSI report is associated with measurement resources, different terminal device receiving units can determine their respective corresponding measurement resources according to their respective corresponding CSI reports. In this way, different terminal device receiving units can perform CSI measurements according to their respective measurement resources and perform their respective CSI reports after the CSI measurements are completed, so that the network can perform link adaptation and the like on different terminal device receiving units respectively according to the CSI reports of different terminal device receiving units.

[0010] Alternatively, in this embodiment, the terminal device receiving unit corresponding to the measurement resources associated with the CSI report can be determined, such that different measurement resources can have their respective corresponding terminal device receiving units, or such that different terminal device receiving units can have their respective corresponding measurement resources. In this way, different terminal device receiving units can perform CSI measurements according to their respective measurement resources.

[0011] Optionally, the terminal device receiving unit corresponding to the CSI report is indicated by CSI report configuration information; the CSI report configuration information is used to configure the CSI report.

[0015] It can be seen that the first CSI report corresponds to the first terminal device receiving unit, and the second CSI report corresponds to the second terminal device receiving unit. In this way, the first terminal device receiving unit can perform CSI measurements according to the measurement resources associated with the first CSI report and perform a CSI report at the time domain position of the first CSI report; correspondingly, the second terminal device receiving unit can perform CSI measurements according to the measurement resources associated with the second CSI report and perform a CSI report at the time domain position of the second CSI report.

[0016] Optionally, the ID of the first CSI report is less than the ID of the second CSI report; or, the first CSI report is the first CSI report and the second CSI report is the second CSI report.

[0017] It can be seen that the CSI report with a smaller ID or the first CSI report corresponds to the first terminal device receiving unit, and the CSI report with a larger ID or the second CSI report corresponds to the second terminal device receiving unit.

[0024] The first CSI report configuration information is used to configure the first CSI report, and the second CSI report configuration information is used to configure the second CSI report.

[0025] In this way, the first CSI report can be configured by the first CSI report configuration information, and it can also indicate that the first CSI report is associated with the second CSI report. Alternatively, the second CSI report can be configured by the second CSI report configuration information, and it can also indicate that the second CSI report is associated with the first CSI report.

[0026] Optionally, the first CSI report is associated with the second CSI report, including:

[0027] The association ID associated with the first CSI report is the same as the association ID associated with the second CSI report.

[0028] In this way, the association between CSI reports is realized through the association ID of the CSI reports for network configuration.

[0032] Optionally, the first CSI report is associated with the second CSI report for the same measurement resource.

[0033] In this way, the first terminal device receiving unit and the second terminal device receiving unit can perform CSI measurements on the same measurement resource, and then perform CSI reports at the time domain positions of the first CSI report and the second reported time domain position respectively.

[0034] Optionally, the same measurement resource includes a first channel measurement resource; the first channel measurement resource is associated with a first resource and a second resource, the first resource includes an NZP-CSI-RS resource and / or a channel state information interference measurement CSI-IM resource, and the second resource includes another NZP CSI-RS resource and / or another CSI-IM resource; the first resource corresponds to the first terminal device receiving unit, and the second resource corresponds to the second terminal device receiving unit.

[0035] In this way, the first terminal device receiving unit can perform CSI measurement based on the first measurement, and the second terminal device receiving unit can perform CSI measurement based on the first measurement.

[0036] Optionally, the terminal device receiving unit corresponding to the measurement resource associated with the CSI report is indicated by the measurement resource configuration information;

[0044] It can be seen that the measurement resource with a smaller ID corresponds to the first terminal device receiving unit, and the measurement resource with a larger ID corresponds to the second terminal device receiving unit. In this way, the first terminal device receiving unit can perform CSI measurement based on the measurement resource with a smaller ID; correspondingly, the second terminal device receiving unit can perform CSI measurement based on the measurement resource with a larger ID.

[0052] Optionally, the first time domain position and the second time domain position are associated with the uplink time slot where the CSI report is located.

[0053] It can be seen that since the first measurement resource and the second measurement resource associated with the CSI report respectively correspond to the first terminal device receiving unit and the second terminal device receiving unit, the first CSI information of the first terminal device receiving unit and the second CSI information of the second terminal device receiving unit can be respectively carried at different time domain positions associated with the uplink time slot where the CSI report is located, thus realizing time-division reporting.

Further, in some other embodiments of the present application, the network device may further include an active antenna unit (AAU). Among them, the CU implements a part of the functions of the network device, and the DU implements another part of the functions of the network device. For example, the CU is responsible for processing non-real-time protocols and services, and implements the functions of the radio resource control (RRC) layer, the service data adaptation protocol (SDAP) layer, and the packet data convergence protocol (PDCP) layer. The DU is responsible for processing physical layer protocols and real-time services, and implements the functions of the radio link control (RLC) layer, the medium access control (MAC) layer, and the physical (PHY) layer. In addition, the AAU can implement some physical layer processing functions, radio frequency processing, and functions related to active antennas. Since the information in the RRC layer will ultimately become the information in the PHY layer, or is transformed from the information in the PHY layer, therefore, in this network deployment, high-layer signaling (such as RRC signaling) can be considered to be generated by the CU and sent by the DU, or sent jointly by the DU and the AAU. It can be understood that the network device may include at least one of the CU, DU, and AAU.

[0125] The S-DCI based M-TRP can be embodied as that one DCI can indicate multiple transmission configuration indicator (TCI) states, or one DCI can include multiple sounding reference signal resource indicator (SRI) fields, etc. Of course, the S-DCI based M-TRP can also be embodied by other concepts / parameters, which are not specifically limited herein.

[0126] The M-DCI based M-TRP can be embodied as that the network configures the values of multiple control resource set pool indexes (control resource set pool index, CORESET pool index, abbreviated as CORESETPoolIndex), such as CORESETPoolIndex = 0, CORESETPoolIndex = 1.

[0138] II. CSI-Related Configuration under Multiple Sub-Receivers

[0139] 1. CSI-Related Configuration

[0140]

Measurement Resources

[0141] The CSI-related configuration may include CSI resource configuration and / or CSI report configuration, and may be defined by the higher-layer parameter CSI-MeasConfig (CSI measurement configuration). Among them, the higher-layer parameter CSI-MeasConfig may indicate / configure / include the following two higher-layer parameters: CSI-ResourceConfig (CSI resource configuration) and CSI-ReportConfig (CSI report configuration).

[0142] Since the higher-layer parameter CSI-ReportConfig may indicate / include the parameter CSI-ResourceConfigId (CSI resource configuration identifier), through the parameter CSI-ResourceConfigId, the higher-layer parameter CSI-ResourceConfig is associated / corresponds / maps to the higher-layer parameter CSI-ReportConfig.

[0143] The higher-layer parameter CSI-ReportConfig may be used for the configuration of CSI reports, that is, to configure CSI reports.

[0144] The high-layer parameter CSI-ResourceConfig can be used to configure the measurement resources for CSI measurement. Additionally, the high-layer parameter CSI-ResourceConfig can configure the parameter CSI-Resource-Set (CSI resource set), and the parameter CSI-Resource-Set can include the most basic channel state information reference signal (CSI-RS) resources.

[0145] The parameter CSI-Resource-Set can indicate / include at least one of the following: the parameter Non-Zero-Power-CSI-RS-ResourceSet (NZP-CSI-RS-ResourceSet), the parameter CSI-Interference-Measurement-ResourceSet (CSI-IM-ResourceSet), and the parameter CSI-Synchronization-Signal-Block-ResourceSet (CSI-SSB-ResourceSet).

[0146] The parameter NZP-CSI-RS-ResourceSet can be used for channel measurement and / or interference measurement; the parameter CSI-IM-ResourceSet can be used for interference measurement; the parameter CSI-SSB-ResourceSet can be used for channel measurement.

[0147] The parameter CSI-ResourceConfig and / or the parameter NZP-CSI-RS-ResourceSet can configure one or more NZP-CSI-RS resource sets. Each NZP-CSI-RS resource set can include K (K≥1) NZP-CSI-RS resources.

[0148] For example, the network device sends CSI resource configuration (CSI resource setting) to the terminal device through an RRC message. Each CSI resource setting includes S (S≥1 and S is an integer) CSI resource sets, and each CSI resource set includes K (K≥1 and K is an integer) NZP-CSI-RS resources. The terminal device can receive CSI-RS on the K NZP-CSI-RS resources indicated by the network device.

[0149] In summary, the measurement resources may include at least one of NZP-CSI-RS resources, CSI-IM resources, and CSI-SSB resources. The NZP-CSI-RS resources can be used for channel measurement and / or interference measurement; the CSI-IM resources can be used for interference measurement; and the CSI-SSB resources can be used for channel measurement.

[0150] In addition, the measurement resources also include channel measurement resources (CMR) and / or interference measurement resources (IMR). Among them, the channel measurement resources refer to the measurement resources used for channel measurement, such as NZP-CSI-RS resources or CSI-SSB resources; the interference measurement resources refer to the measurement resources used for interference measurement, such as NZP-CSI-RS resources and CSI-IM resources.

[0151]

Time Domain Behavior

[0152] The time domain behavior may include periodic, semi-persistent, and aperiodic. Taking CSI-RS as an example, the following is an illustration.

[0153] The time domain behavior of CSI-RS may include periodic CSI-RS, aperiodic CSI-RS, and non-semi-persistent CSI-RS, and the time domain behavior of CSI-RS can be indicated by higher layer parameters (such as resource type resourceType).

[0154] For periodic CSI-RS, after the network device configures the periodic CSI-RS, the network device will send the CSI-RS periodically.

[0155] For aperiodic CSI-RS, after the network device configures the aperiodic CSI-RS, the network device will not immediately send the CSI-RS. Instead, it will first send a signaling message to notify the terminal device, and then send the aperiodic CSI-RS to the terminal device.

[0156] For semi-persistent CSI-RS, after the network device configures the semi-persistent CSI-RS, the network device will not immediately send the CSI-RS. Instead, it will first send a signaling message to notify the terminal device, and then after the activation signaling message takes effect, the network device will send the semi-persistent CSI-RS to the terminal device. Among them, once the network device triggers the transmission of semi-persistent CSI-RS, it will send the CSI-RS periodically, unless the network device issues a deactivation signaling message.

[0157] The time-domain behavior of CSI reports may include periodic CSI reports, aperiodic CSI reports, semi-persistent CSI reports carried on the physical uplink control channel (PUCCH), and semi-persistent CSI reports carried on the physical uplink shared channel (PUSCH), and the time-domain behavior of CSI reports may be indicated by higher-layer parameters (such as the reporting configuration type (reportConfigType)).

[0158] For aperiodic CSI reports and semi-persistent CSI reports carried on the PUSCH, the network device also configures the higher-layer parameters TriggerState and the higher-layer parameter reportTriggerSize for use in conjunction with the CSI request field in the downlink control information (DCI).

[0159] For periodic CSI reports, after configuring the periodic CSI-RS Resource and Report parameters via RRC signaling, they will take effect immediately without the need to activate / trigger CSI-RS transmission and CSI reports via MAC-CE / DCI.

[0160] For semi-persistent CSI reports carried on the PUCCH, if semi-persistent CSI-RS transmission is configured via an RRC message, it is necessary to first activate CSI-RS transmission via MAC CE1 and then activate CSI reporting via MAC CE2; if periodic CSI-RS transmission is configured via an RRC message, there is no need to activate CSI-RS transmission via MAC CE1, and only CSI reporting needs to be activated via MAC CE2.

[0161] For semi-persistent CSI reports carried on the PUSCH, if semi-persistent CSI-RS transmission is configured via an RRC message, it is necessary to first activate CSI-RS transmission via MAC CE1 and then trigger CSI reporting via DCI; if periodic CSI-RS transmission is configured via an RRC message, there is no need to activate CSI-RS transmission via MAC CE1, and only CSI reporting needs to be triggered via DCI.

[0162] It should be noted that for DCI, the DCI can be DCI format 0_1 scrambled with SP-CSI-RNTI (semi-persistent CSI-RNTI), and the CSI request field in the DCI can be associated with the corresponding trigger state (TriggerState) through the setting of the codepoint. The CSI-ReportConfig associated will be defined in the TriggerState, so that the CSI-ReportConfig associated with the semi-persistent CSI report on the PUSCH can be found through the TriggerState.

[0163] For the aperiodic CSI report, the aperiodic CSI report is triggered by DCI, and the process is similar to the above semi-persistent CSI report. When associating the corresponding TriggerState through the codepoint of the CSI request field in DCI format 0_1 / 0_2, it is different from the DCI trigger in the above semi-persistent CSI report. If the value of the CSI request field is 0, it means that triggering the semi-periodic CSI report is not required; if the value of the CSI request field is 1, it means that the aperiodic CSI report associated with TriggerState 1 is triggered, and so on.

[0164] It should be noted that the combination of CSI report configuration and CSI-RS resource configuration is shown in Table 1.

[0165] Table 1

[0166]

[0167]

CSI Measurement and CSI Reporting

[0168] During the CSI measurement, CSI acquisition, and CSI reporting processes, the terminal device can perform CSI measurement on the downlink channel according to the measurement resources to obtain channel information / CSI information, and then report the channel information / CSI information to the network device.

[0169] Optionally, the CSI information includes at least one of the following: CSI reference signal resource indication index (CSI-RS Resource Indicator, CRI), synchronization signal block resource indication index (SSB resource indicator, SSBRI), rank indication index (RI), precoding matrix indication index (precoding matrix indicator, PMI), channel quality indication index (channel quality indicator, CQI), layer indication index (layer indicator, LI), time-domain channel property (TDCP), etc.

[0170] It should be noted that the CRI (or SSBRI) can represent the CSI-RS (or SSB) resource recommended (or selected) by the terminal device. Among them, one CSI-RS (or SSB) resource can represent a beam or antenna direction.

[0171] The RI can represent the number of layers / rank recommended (or selected) by the terminal device, and the number of layers can determine which codebook. Among them, each number of layers corresponds to a codebook, and a codebook consists of one or more codewords. For example, a codebook with 2 layers or a codebook with 1 layer.

[0172] The PMI can represent the index of the codeword in the codebook recommended (or selected) by the terminal device, or the quantized precoding information. Among them, one codeword corresponds to one precoding matrix. The RI and PMI can represent the number of layers and precoding matrix recommended by the terminal device as a whole.

[0173] The CQI can represent the quality of the current channel feedback by the terminal device to the network device. Among them, the terminal device needs to calculate the CQI.

[0174] Optionally, the channel information may refer to the relevant information obtained by channel measurement according to reference signals (such as CSI-RS, DMRS, SSB, etc.)

[0175] For example, the channel information includes at least one of the following: channel matrix H, equivalent channel matrix, precoding matrix W (the precoding matrix W can be derived from the channel matrix H), right singular vector V of the channel matrix H, square matrix H T Eigenvector of H (i.e., conjugate transpose H of the channel matrix TThe eigenvector of the matrix obtained by multiplying by the channel matrix H, at least one vector associated with the channel matrix H (such as at least one vector under a certain transformation of the channel matrix H, etc.), the time-domain information of the channel, the channel information in the delay-doppler domain, CRI, SSBRI, RI, PMI, CQI, LI, etc.

[0176]

CSI reference resource

[0177] It should be noted that one CSI report corresponds to one CSI reference resource. For example, for a periodic CSI report, CSI is reported periodically, and each CSI report corresponds to a CSI reference resource.

[0178] The time domain of the CSI reference resource can be a time slot, and the frequency domain of the CSI reference resource can be the frequency resource related to obtaining CSI measurement. Optionally, when the uplink time slot where the CSI report is located is time slot n′, the downlink time slot where the CSI reference resource is located is time slot K offset represents the offset configured by the higher layer, represents in frequency range 1 and K offset =0 for the subcarrier spacing configuration, μ DL represents the downlink subcarrier spacing configuration.

[0179] Since the CSI reference resource is a downlink resource, the time domain of the CSI reference resource is a downlink time slot. Thus, time slot n represents the downlink time slot corresponding to time slot n′, and the calculation is as follows:

[0180]

[0181] where μ UL represents the uplink subcarrier spacing configuration, represents the downlink time slot offset, μ offset,DL represents the maximum value of the minimum of the downlink subcarrier spacing configuration in the primary cell (Pcell) / primary secondary cell (PScell) and the minimum of the downlink subcarrier spacing configuration in the secondary cell (Scell), represents the uplink time slot offset, μ offset,UL represents the maximum value of the minimum of the uplink subcarrier spacing configuration in the Pcell / PScell and the minimum of the uplink subcarrier spacing configuration in the Scell.

[0182] n CSI_refIndicates the slot offset between slot n and the valid downlink slot, and the CSI reference resource is located in this valid downlink slot. Among them, whether a downlink slot is a "valid downlink slot" needs to meet the following conditions: the downlink slot includes at least one downlink symbol or flexible symbol configured by high-layer signaling; and / or, the downlink slot is not within the configured measurement gap.

[0183] Optionally, for periodic or semi-persistent CSI reporting, if the CSI report is associated with a channel measurement resource (such as a CSI-RS / SSB for channel measurement), then n CSI_ref is the minimum value greater than or equal to in which the CSI reference resource corresponding to the CSI report is located in the valid downlink slot.

[0184] For example, assume that the uplink and downlink subcarrier spacing configurations are the same, i.e., μ DL = μ UL = 0. Starting from the minimum value greater than or equal to let n CSI_ref be calculated as and determine whether slot n - 4 is a valid downlink slot. If slot n - 4 is a valid downlink slot, the CSI reference resource is located in slot n - 4; if slot n - 4 is not a valid downlink slot, then let n CSI_ref be calculated as and determine whether slot n - 5 is a valid downlink slot. If slot n - 5 is a valid downlink slot, the CSI reference resource is located in slot n - 5; if slot n - 5 is not a valid downlink slot, continue to look forward until a valid downlink slot is found.

[0185] Optionally, for periodic or semi-persistent CSI reporting, if the CSI report is associated with multiple channel measurement resources (such as multiple CSI-RS / SSBs for channel measurement), then n CSI_ref is the minimum value greater than or equal to in which the CSI reference resource corresponding to the CSI report is located in the valid downlink slot.

[0186] Optionally, for aperiodic CSI reporting, if the DCI used to trigger the CSI report and the CSI report are in the same slot, the CSI reference resource is located in the slot where the DCI is located; otherwise, n CSI_ref is the minimum value greater than or equal to in which the CSI reference resource corresponding to the CSI report is located in the valid downlink slot, represents the number of symbols included in a slot, and Z' represents the processing time for CSI calculation.

[0187] Optionally, the CSI reference resource can have the following two functions.

[0188] Function 1: Used to calculate the channel quality indicator (CQI)

[0189] Channel measurement essentially depends on the implementation of the terminal device. For example, some terminal devices have very strong capabilities and can meet the target block error rate (BLER) requirements when using a certain modulation and coding scheme (MCS) at SINR = 10 dB. However, some terminal devices have weaker capabilities and need SINR = 12 dB to meet the target BLER (the target BLER is configured by the network device) requirements. Therefore, if the SINR measured by two terminal devices is 10 dB, the CQI values may be different when feeding back the CQI.

[0190] In addition, even for the same terminal device, different transport block sizes (TBS) of data packets will result in different BLERs. For example, SINR = 10 dB. If the current transmitted TBS is 1000 bits and a specific MCS is selected for transmission, its BLER is 0.01. If TBS = 500 bits is used and the same MCS is selected for transmission, its corresponding BLER may be 0.1. The two are different.

[0191] Therefore, when quantifying the CQI, the concept of CSI reference resources is needed so that the terminal device can obtain CQI / CSI through the CSI reference resources.

[0192] Suppose the terminal device uses CSI-RS for channel measurement to obtain the channel state, such as SINR. The terminal device will assume that a downlink data packet is transmitted on the CSI reference resource, and the corresponding channel state is the one measured by CSI-RS. At this time, the terminal device selects a CQI from the CQI table, and this CQI can make the BLER less than the target BLER when the assumed transmitted downlink data packet is transmitted in the measured channel state.

[0193] Function 2: Used to determine the measurement resources associated with the CSI report

[0194] A network device may configure one or more measurement resources for CSI measurement to a terminal device. Among them, the time-domain position of the measurement resources associated with the CSI report may be before the CSI reference resources corresponding to the CSI report. That is to say, the measurement resources before the CSI reference resources corresponding to the CSI report may be used as the measurement resources associated with the CSI report. As for which measurements can be used as the measurement resources associated with the CSI report, it can be configured by high-layer signaling, specified by the protocol, pre-configured, or determined autonomously by the terminal device, etc.

[0195] For example, taking periodic measurement resources as an example, as Figure 2 shown, the periodic measurement resources include the measurement resources associated with the CSI report, and the time-domain position of the measurement resources associated with the CSI report is before the CSI reference resources corresponding to the CSI report. That is to say, only the measurement resources before the CSI reference resources corresponding to the CSI report may be used as the measurement resources associated with the CSI report. As for which one or which resources of the measurements can be used as the measurement resources associated with the CSI report, it can be further configured by the network through high-layer signaling. For example, the network may configure the resource closest to / adjacent to the CSI reference resource as the measurement resource associated with the CSI report.

[0196] It should be noted that this embodiment does not specifically limit the content in the "CSI reference resources", and this part of the content does not exclude new content included in the further evolution of the standard protocol.

[0197] 2. CSI-related configurations under multiple sub-receivers

[0198] Currently, the related research on CSI regards the terminal device as a receiver with receiving antennas. In this way, during the CSI measurement and CSI reporting process, the receiver can perform CSI measurement on the downlink channel according to the measurement resources to obtain channel information / CSI information, and then report the channel information / CSI information to the network for link adaptation, etc.

[0199] However, as the number of receiving antennas of the receiver increases, in order to ensure that the receiver has low complexity under a large number of receiving antennas, the receiver may be split into multiple sub-receivers, so that each sub-receiver has a smaller number of receiving antennas and / or lower processing complexity.

[0200] For example, in this embodiment, it can be determined whether the receiver needs to be split by whether the number of receiving antennas of the terminal device exceeds a preset value (such as 4). If the number of receiving antennas is less than or equal to the preset value, the receiver is not split; if the number of receiving antennas is greater than the preset value, the receiver is split. Among them, the "number of receiving antennas of the terminal device" here can be the total number of receiving days of the terminal device, or the number of receiving days of the receiver.

[0201] In addition, the receiver can be implemented through an antenna panel, and multiple sub-receivers can be implemented through multiple antenna panels. At the same time, in the face of multiple sub-receivers / multiple antenna panels, it is necessary to group the terminal device receive antenna ports (UE receive antenna port) to obtain multiple terminal device receive antenna port groups, and the multiple terminal device receive antenna port groups correspond one-to-one with the multiple sub-receivers / multiple antenna panels.

[0202] It should be noted that the "receiver", "sub-receiver", "antenna panel", and "terminal device receive antenna port group" mentioned in this embodiment can be logical units, physical units, entity units, hardware units, logical units, or software units, and no specific restrictions are made in this regard. Among them, the receiver can be a physical receiver, a logical receiver, etc., and no restrictions are made in this regard. The sub-receiver can be a physical sub-receiver, a logical sub-receiver, etc., and no restrictions are made in this regard. The receive antenna can be a physical receive antenna, a logical receive antenna, etc., and no restrictions are made in this regard. The receive antenna port group can be a physical receive antenna port group, a logical receive antenna port group, etc., and no restrictions are made in this regard.

[0203] For the sake of convenience of description, in the following embodiments, the "terminal device receive antenna port group", "terminal device antenna panel", or "terminal device sub-receiver" will be collectively referred to as the "terminal device receive unit" for description.

[0204] Since the maximum number of receive antennas corresponding to the terminal device receive unit is a preset value (such as 4), the maximum number of layers / maximum rank corresponding to the terminal device receive unit is this preset value.

[0205] In addition, since different terminal device receive units may be independent of each other, different terminal device receive units need to correspond to their respective CSI-related configurations. In this way, different terminal device receive units can perform CSI measurement, CSI acquisition, CSI report acquisition, and CSI report reporting according to their respective CSI-related configurations, so that different terminal device receive units can obtain their respective corresponding channel information / CSI information and report it to the network, so that the network can perform link adaptation on different terminal device receive units respectively according to the CSI reports of different terminal device receive units.

[0206] For example, taking multiple terminal device receive units as two 4-receive-antenna sub-receivers (4Rx sub-receivers) as an example, as Figure 3 shown. In Figure 3In this case, the terminal device 310 implements eight receive antennas through two independent 4-receive-antenna sub-receivers (i.e., the 4Rx sub-receiver 3101 and the 4Rx sub-receiver 3102). That is to say, the 8Rx receiver is split into two 4Rx sub-receivers to reduce the complexity of the terminal device 310. Among them, the 4Rx sub-receiver 3101 has corresponding CSI-related configurations, and the 4Rx sub-receiver 3102 has corresponding CSI-related configurations. In addition, the network device 320 sends multiple beams, and the multiple beams include the beam 3201 and the beam 3202. Among them, the beam 3201 faces the 4Rx sub-receiver 3101, and the beam 3202 faces the 4Rx sub-receiver 3102.

[0207] Next, this embodiment will exemplify the "CSI-related configuration of the terminal device receiving unit" from the following two solutions respectively. Among them, each solution can be interrelated or independent. At the same time, the same content between different solutions can be referenced to each other, and this embodiment will not repeat the same content.

[0208]

Solution 1

[0209] a. Description

[0210] In "Solution 1", this embodiment can determine the terminal device receiving unit corresponding to the CSI report. In this way, the CSI report can have its own corresponding terminal device receiving unit, or the terminal device receiving unit can have its own corresponding CSI report, so as to realize the CSI-related configuration of the terminal device receiving unit.

[0211] At the same time, since the CSI report is associated with measurement resources, the terminal device receiving unit can determine its own corresponding measurement resources according to its own corresponding CSI report. In this way, the terminal device receiving unit can perform CSI measurement according to its own measurement resources and report the CSI report after the CSI measurement is completed, so that the network can perform link adaptation on the terminal device receiving unit according to the CSI report of the terminal device receiving unit.

[0212] It should be noted that in "Solution 1", this embodiment can have one or more terminal device receiving units corresponding to one CSI report, or one or more terminal device receiving units corresponding to multiple CSI reports, and no specific limitation is made on this.

[0213] Optionally, different CSI reports correspond to different terminal device receiving units. In this way, different terminal device receiving units can perform CSI measurement according to their respective measurement resources and report their respective CSI reports after the CSI measurement is completed, so that the network can perform link adaptation on different terminal device receiving units respectively according to the CSI reports of different terminal device receiving units.

[0214] For example, taking the case where the CSI report includes a first CSI report and a second CSI report, and the first CSI report and the second CSI report are different CSI reports, the terminal device receiving unit includes a first terminal device receiving unit corresponding to the first CSI report and a second terminal device receiving unit corresponding to the second CSI report, and the first terminal device receiving unit and the second terminal device receiving unit are different terminal device receiving units. It can be seen that the first CSI report corresponds to the first terminal device receiving unit, and the second CSI report corresponds to the second terminal device receiving unit.

[0215] In this way, the first terminal device receiving unit can perform CSI measurement according to the measurement resources associated with the first CSI report and report CSI at the time domain position of the first CSI report; correspondingly, the second terminal device receiving unit can perform CSI measurement according to the measurement resources associated with the second CSI report and report CSI at the time domain position of the second CSI report.

[0216] Optionally, the ID / index of the first CSI report is less than the ID / index of the second CSI report; the first terminal device receiving unit is the first terminal device receiving unit, and the second terminal device receiving unit is the second terminal device receiving unit.

[0217] Optionally, the first CSI report is the first CSI report, and the second CSI report is the second CSI report; the first terminal device receiving unit is the first terminal device receiving unit, and the second terminal device receiving unit is the second terminal device receiving unit.

[0218] It should be noted that when the network configures multiple CSI reports, the multiple CSI reports may be sorted in the order of network configuration. At this time, the first CSI report among the multiple CSI reports may refer to the CSI report first configured by the network, and the second CSI report may refer to the CSI report configured by the network after the first CSI report, and so on.

[0219] Alternatively, the multiple CSI reports may be sorted in ascending order of ID or index. At this time, the first CSI report among the multiple CSI reports may refer to the CSI report with the smallest ID / index, and the second CSI report may refer to the CSI report with the second smallest ID / index, and so on.

[0220] Alternatively, the multiple CSI reports may be sorted in descending order of ID or index. At this time, the first CSI report among the multiple CSI reports may refer to the CSI report with the largest ID / index, and the second CSI report may refer to the CSI report with the second largest ID / index, and so on.

[0221] Alternatively, the time domain positions of multiple CSI reports have a sequential order. In this case, the first CSI report among the multiple CSI reports may refer to the CSI report with the earliest / latest / frontmost time domain position, the second CSI report may refer to the CSI report whose time domain position is immediately after the time domain position of the first CSI report, and so on. Among them, the time domain position of the CSI report may include the reporting time slot / reporting time, etc., of the CSI report.

[0222] Alternatively, the time domain positions of the measurement resources associated with multiple CSI reports have a sequential order. In this case, the first CSI report among the multiple CSI reports may refer to the CSI report with the earliest / frontmost time domain position of the measurement resources, the second CSI report may refer to the CSI report whose time domain position of the measurement resources is immediately after the time domain position of the measurement resources associated with the first CSI report, and so on.

[0223] Correspondingly, the receiving units of multiple terminal devices may be sorted in descending or ascending order according to the ID or index, which will not be elaborated here.

[0224] b. Determine the receiving unit of the terminal device corresponding to the CSI report

[0225] It should be noted that in this embodiment, the receiving unit of the terminal device corresponding to the CSI report can be determined according to network configuration, independently determined by the terminal device, or specified by the protocol. The following will be specifically described separately.

[0226] Network configuration refers to configuring / indicating the receiving unit of the terminal device corresponding to the CSI report through high-layer signaling (such as MAC signaling or RRC signaling, etc.) / DCI / system information, etc. In this way, through network configuration, it is possible to achieve explicit indication of the receiving unit of the terminal device corresponding to the CSI report, so that the receiving unit of the terminal device can receive its corresponding CSI report.

[0227] For example, taking the interaction between the network device and the terminal device as an example, an example of "network configuration" will be described. As Figure 4 shown, Figure 4 is a schematic flowchart of a communication method according to an embodiment of the present application. Among them, the method includes the following steps:

[0228] S410. The network device sends the first information, and the first information indicates the receiving unit of the terminal device corresponding to the CSI report.

[0229] Correspondingly, the terminal device receives the first information.

[0230] Among them, the first information may be carried by high-layer signaling (such as RRC signaling).

[0231] In this way, the receiving unit of the terminal device for the CSI report is configured through the first information.

[0232] Optionally, the first information includes CSI report configuration information for configuring the CSI report, and the CSI report configuration information indicates the receiving unit of the terminal device corresponding to the CSI report. In this way, the receiving unit of the terminal device for the network-configured CSI report is implemented through the CSI report configuration information.

[0233] For example, the CSI report configuration information may include the ID of the receiving unit of the terminal device, so as to indicate the receiving unit of the terminal device corresponding to the CSI report through the CSI report configuration information.

[0234] The autonomous determination by the terminal device means that the terminal device can autonomously determine the receiving unit of the terminal device corresponding to the CSI report according to network conditions and device requirements / capabilities. In this way, through the autonomous determination of the terminal device, it can be ensured that the CSI report corresponding to the receiving unit of the terminal device itself is more adapted to its own requirements / capabilities.

[0235] Of course, the terminal device can report the result determined by itself to the network device so that the network device can know the selection of the terminal device.

[0236] The protocol stipulation means that the standard protocol directly defines the receiving unit of the terminal device corresponding to the CSI report.

[0237] c. CSI reports associated with different measurement resources

[0238] The network can configure CSI reports associated with different measurement resources. At this time, these CSI reports may be associated with different measurement resources and may also correspond to different receiving units of terminal devices.

[0239] For these CSI reports, in this embodiment, it can be configured by the network that some of these CSI reports can be associated with each other. Among them, the purpose of establishing the association is that for two CSI reports with an established association, one of the two CSI reports can use the channel measurement resources associated with the other CSI report as its interference measurement resources. In this way, one CSI report can perform CSI interference measurement according to the channel measurement resources associated with the other CSI report.

[0240] For example, taking the first CSI report corresponding to the first receiving unit of the terminal device and the second CSI report corresponding to the second receiving unit of the terminal device as an example, in this embodiment, the network can configure the first CSI report and the second CSI report to be associated with different measurement resources respectively, and the first CSI report is associated with the second CSI report. In this way, the channel measurement resources associated with the second CSI report can be used for the interference measurement of the first CSI report, and the channel measurement resources associated with the first CSI report can be used for the interference measurement of the second CSI report.

[0241] Optionally, the following two methods can be used in this embodiment to establish the association between CSI reports:

[0242] Method 1: The network directly configures / indicates the association between CSI reports

[0243] In "Method 1", the association between CSI reports can be directly configured / indicated by the higher layer signaling (such as RRC signaling or MAC signaling) or DCI in this embodiment.

[0244] For example, taking the first CSI report corresponding to the first terminal device receiving unit and the second CSI report corresponding to the second terminal device receiving unit as an example, the network device sends the first CSI report configuration information and the second CSI report configuration information; correspondingly, the terminal device receives the first CSI report configuration information and the second CSI report configuration information. Among them, the first CSI report configuration information is used to configure the first CSI report, and the second CSI report configuration information is used to configure the second CSI report. At the same time, the first CSI report configuration information or the second CSI report configuration information indicates that the first CSI report is associated with the second CSI report. In this way, the association between CSI reports is configured by the network through the first CSI report configuration information or the second CSI report configuration information.

[0245] Method 2: The network configures / indicates the association ID of CSI reports

[0246] In "Method 2", the association ID of CSI reports can be configured / indicated by the higher layer signaling (such as RRC signaling or MAC signaling) or DCI in this embodiment. Among them, the CSI reports with the same association ID are associated with each other.

[0247] For example, taking the first CSI report corresponding to the first terminal device receiving unit and the second CSI report corresponding to the second terminal device receiving unit as an example, the network device sends the first CSI report configuration information and the second CSI report configuration information; correspondingly, the terminal device receives the first CSI report configuration information and the second CSI report configuration information. Among them, the first CSI report configuration information is used to configure the first CSI report, and the first CSI report configuration information indicates the association ID of the first CSI report; the second CSI report configuration information is used to configure the second CSI report, and the second CSI report configuration information indicates the association ID of the second CSI report. At the same time, the association ID of the first CSI report is the same as the association ID of the second CSI report. In this way, the association between CSI reports is configured by the network through the association ID of CSI reports.

[0248] d. Associate CSI reports with the same measurement resources

[0249] The network may configure CSI reports that are associated with the same measurement resources. In this case, these CSI reports are associated with the same measurement resources, but may correspond to different terminal device receiving units.

[0250] For example, taking the CSI reports and there are multiple terminal device receiving units as an example, the CSI reports include a first CSI report and a second CSI report. The first CSI report and the second CSI report are different CSI reports, and the measurement resources associated with the first CSI report and the second CSI report are the same. The terminal device receiving units include a first terminal device receiving unit corresponding to the first CSI report and a second terminal device receiving unit corresponding to the second CSI report, and the first terminal device receiving unit and the second terminal device receiving unit are different terminal device receiving units.

[0251] In this way, the first terminal device receiving unit and the second terminal device receiving unit can perform CSI measurements based on the same measurement resources, and then perform CSI reports at the time domain positions of the first CSI report and the second reported time domain position respectively.

[0252] Optionally, the same measurement resources associated with these CSI reports may include channel measurement resources and / or interference measurement resources. That is to say, these CSI reports are associated with the same channel measurement resources and / or interference measurement resources.

[0253] For example, taking there are multiple CSI reports and the CSI reports include a first CSI report and a second CSI report as an example, the network configures the channel measurement resources and / or interference measurement resources associated with the first CSI report and the second CSI report to be the same.

[0254] Optionally, if the same measurement resources associated with these CSI reports include a channel measurement resource, and this channel measurement resource is associated with multiple NZP-CSI-RS resources for interference measurement and / or multiple CSI-IM resources, then the multiple NZP-CSI-RS resources and / or the multiple CSI-IM resources may correspond to the multiple terminal device receiving units corresponding to these CSI reports.

[0255] In this way, these terminal device receiving units can perform CSI measurements according to their respective NZP-CSI-RS resources for channel measurement and / or NZP-CSI-RS resources for interference measurement and / or CSI-IM resources, and perform their respective CSI reports after the CSI measurements are completed.

[0256] For example, taking the case where the first CSI report corresponds to the first terminal device receiving unit and the second CSI report corresponds to the second terminal device receiving unit as an example, the first CSI report and the second CSI report are associated with a first channel measurement resource, the first channel measurement resource is associated with a first resource and a second resource, the first resource includes an NZP-CSI-RS resource for interference measurement and / or a CSI-IM resource, and the second resource includes another NZP-CSI-RS resource for interference measurement and / or another CSI-IM resource. Among them, the first resource corresponds to the first terminal device receiving unit, and the second resource corresponds to the second terminal device receiving unit.

[0257] In this way, the first terminal device receiving unit can perform CSI measurement according to the first measurement, and the second terminal device receiving unit can perform CSI measurement according to the first measurement.

[0258] Optionally, the multiple NZP-CSI-RS resources and / or the multiple CSI-IM resources corresponding to the multiple terminal device receiving units corresponding to these CSI reports can be network-configured, determined autonomously by the terminal device, or specified by the protocol.

[0259] For example, taking network configuration as an example, the network device sends multiple measurement resource configuration information, the multiple measurement resource configuration information is used to configure the multiple NZP-CSI-RS resources and / or the multiple CSI-IM resources, and the multiple measurement resource configuration information indicates that the multiple NZP-CSI-RS resources and / or the multiple CSI-IM resources correspond to the multiple terminal device receiving units corresponding to these CSI reports.

[0260]

Solution 2

[0261] a. Description

[0262] In "Solution 2", this embodiment can determine the terminal device receiving unit corresponding to the measurement resource associated with the CSI report, so that different measurement resources can have their respective corresponding terminal device receiving units, or different terminal device receiving units can have their respective corresponding measurement resources, thereby realizing the CSI-related configuration of the terminal device receiving unit. In this way, different terminal device receiving units can perform CSI measurement according to their respective corresponding measurement resources.

[0263] Optionally, different measurement resources correspond to different terminal device receiving units.

[0264] For example, taking the case where a CSI report associates a first measurement resource and a second measurement resource, and the first measurement resource and the second measurement resource are different measurement resources, the terminal device receiving unit includes a first terminal device receiving unit corresponding to the first measurement resource and a second terminal device receiving unit corresponding to the second measurement resource, and the first terminal device receiving unit and the second terminal device receiving unit are different terminal device receiving units. It can be seen that the first measurement resource corresponds to the first terminal device receiving unit, and the second measurement resource corresponds to the second terminal device receiving unit.

[0265] In this way, the first terminal device receiving unit can perform CSI measurement according to the first measurement resource, and the second terminal device receiving unit can perform CSI measurement according to the second measurement resource.

[0266] Optionally, the ID / index of the first measurement resource is less than the ID / index of the second measurement resource; the first terminal device receiving unit is the first terminal device receiving unit, and the second terminal device receiving unit is the second terminal device receiving unit.

[0267] Optionally, the first measurement resource is the first first measurement resource, and the second measurement resource is the second first measurement resource; the first terminal device receiving unit is the first terminal device receiving unit, and the second terminal device receiving unit is the second terminal device receiving unit

[0268] It should be noted that when the network configures a CSI report to associate multiple measurement resources, the multiple measurement resources may be sorted according to the order of network configuration. At this time, the first measurement resource among the multiple measurement resources may refer to the earliest measurement resource among the network-configured measurement resources, and the second measurement resource may refer to the measurement resource after the first measurement resource, and so on.

[0269] Alternatively, the multiple measurement resources may be sorted in ascending order of ID or index. At this time, the first measurement resource among the multiple measurement resources may refer to the measurement resource with the smallest ID / index, and the second measurement resource may refer to the measurement resource with the second smallest ID / index, and so on.

[0270] Alternatively, the multiple measurement resources may be sorted in descending order of ID or index. At this time, the first measurement resource among the multiple measurement resources may refer to the measurement resource with the largest ID / index, and the second measurement resource may refer to the measurement resource with the second largest ID / index, and so on.

[0271] Alternatively, the time domain positions of the multiple measurement resources have a sequential order. At this time, the first measurement resource among the multiple measurement resources may refer to the earliest / most forward / frontmost measurement resource in the time domain position, and the second measurement resource may refer to the measurement resource whose time domain position is immediately after the time domain position of the first measurement resource, and so on.

[0272] Correspondingly, multiple terminal device receiving units may be sorted in descending or ascending order according to the ID or index, which will not be elaborated here.

[0273] b. Determine the terminal device receiving unit corresponding to the measurement resource

[0274] It should be noted that in this embodiment, the terminal device receiving unit corresponding to the measurement resource can be determined according to network configuration, independently determined by the terminal device, or specified by the protocol. Specific descriptions are given below respectively.

[0275] Network configuration refers to configuring / indicating the terminal device receiving unit corresponding to the measurement resource through high-layer signaling (such as MAC signaling or RRC signaling, etc.) / DCI / system information, etc. In this way, through network configuration, it is possible to explicitly indicate the terminal device receiving unit corresponding to the measurement resource, so that the terminal device receiving unit can have its own corresponding measurement resource.

[0276] For example, taking the interaction between the network device and the terminal device as an example, an example description of "network configuration" is given. As Figure 5 shown, Figure 5 is a schematic flowchart of another communication method according to an embodiment of the present application. Among them, the method includes the following steps:

[0277] S510. The network device sends a second piece of information, and the second piece of information indicates the terminal device receiving unit corresponding to the measurement resource associated with the CSI report.

[0278] Correspondingly, the terminal device receives the second piece of information.

[0279] Among them, the second piece of information can be carried by high-layer signaling (such as RRC signaling).

[0280] In this way, the network configuration of the terminal device receiving unit corresponding to the measurement resource is achieved through the second piece of information.

[0281] Optionally, the second piece of information includes measurement resource configuration information, which is used to configure the measurement resource associated with the CSI report, and the measurement resource configuration information indicates the terminal device receiving unit corresponding to the measurement resource associated with the CSI report. In this way, the network configuration of the terminal device receiving unit corresponding to the measurement resource is achieved through the measurement resource configuration information.

[0282] For example, the measurement resource configuration information may include the ID of the terminal device receiving unit, so as to indicate the terminal device receiving unit corresponding to the measurement resource through the measurement resource configuration information.

[0283] The autonomous determination by the terminal device means that the terminal device can autonomously determine the terminal device receiving unit corresponding to the measurement resource associated with the CSI report according to the network conditions and the device requirements / capabilities. In this way, through the autonomous determination by the terminal device, it can be ensured that the measurement resource corresponding to the terminal device receiving unit itself is more adapted to its own requirements / capabilities.

[0284] Of course, the terminal device can report the result of its own determination to the network device so that the network device can know the selection of the terminal device.

[0285] The protocol stipulation means that the standard protocol directly defines the terminal device receiving unit corresponding to the measurement resource.

[0286] c. Time-division reporting of channel information / CSI information

[0287] It should be noted that different terminal device receiving units can perform CSI measurements according to their respective corresponding measurement resources to obtain their respective channel information / CSI information. At this time, the terminal device in this embodiment can perform time-division reporting on the channel information / CSI information of different terminal device receiving units.

[0288] This is because when a CSI report is associated with multiple measurement resources and the multiple measurement resources respectively correspond to different terminal device receiving units, although different terminal device receiving units can perform CSI measurements according to their respective corresponding measurement resources to obtain their respective channel information / CSI information, different terminal device receiving units may correspond to the same CSI report. At this time, in order to implement the reporting of the channel information / CSI information of these terminal device receiving units, time-division reporting needs to be considered in this embodiment.

[0289] When specifically implemented, when a CSI report is associated with multiple measurement resources and the multiple measurement resources respectively correspond to different terminal device receiving units, the channel information / CSI information of different terminal device receiving units can be carried at different time-domain positions, and these different time-domain positions are associated with the time-domain position of this CSI report.

[0290] In this way, time-division reporting is achieved by carrying the channel information / CSI information at different time-domain positions.

[0291] For example, taking the case where the first measurement resource corresponds to the first terminal device receiving unit and the second measurement resource corresponds to the second terminal device receiving unit as an example, the first terminal device receiving unit performs CSI measurement according to the first measurement resource to obtain first CSI information, and sends the first CSI information at the first time domain position; correspondingly, the network device receives the first CSI information. Additionally, the second terminal device receiving unit performs CSI measurement according to the second measurement resource to obtain second CSI information, and sends the second CSI information at the second time domain position; correspondingly, the network device receives the second CSI information. Herein, the first time domain position and the second time domain position are different time domain positions.

[0292] In this way, the first CSI information of the first terminal device receiving unit is carried at the first time domain position, and the second CSI information of the second terminal device receiving unit is carried at the second time domain position, thereby achieving time-division reporting.

[0293] Optionally, the time domain position may include subframes, time slots, symbols, or mini time slots, etc.

[0294] For example, the time domain position of the CSI report includes the uplink time slot where the CSI report is located.

[0295] Optionally, these different time domain positions may include the uplink time slot where the CSI report is located and the uplink time slots after the uplink time slot where the CSI report is located, thereby realizing the association between these different time domain positions and the uplink time slot where the CSI report is located.

[0296] For example, taking the case where the first CSI information is carried at the first time domain position and the second CSI information is carried at the second time domain position as an example, the association between the first time domain position and the second time domain position and the uplink time slot where the CSI report is located includes:

[0297] The first time domain position includes a first uplink time slot, and the first uplink time slot is the uplink time slot where the CSI report is located or an available uplink time slot after the uplink time slot where the CSI report is located; the second time domain position includes a second uplink time slot, and the second uplink time slot is an available uplink time slot after the uplink time slot where the CSI report is located; the first uplink time slot and the second uplink time slot are different available uplink time slots.

[0298] In this way, the first CSI information and the second CSI information can be carried on different available uplink time slots, and these two uplink time slots are associated with the uplink time slot where the CSI report is located, thereby achieving time-division reporting.

[0299] Optionally, the uplink time slots after the uplink time slot where the CSI report is located may be adjacent or non-adjacent.

[0300] For example, taking the case where the first CSI information is carried on the first uplink time slot and the second CSI information is carried on the second uplink time slot as an example, the first uplink time slot and the second uplink time slot are two adjacent or non - adjacent uplink time slots.

[0301] Optionally, the CSI information of the receiving unit of the terminal device includes indication information for indicating itself. In this way, the network device can know which receiving unit of the terminal device the CSI information is according to the indication information, so as to distinguish the CSI information of each receiving unit of different terminal devices.

[0302] For example, taking the case where the first CSI information of the first receiving unit of the terminal device is carried on the first time - domain position and the second CSI information of the second receiving unit of the terminal device is carried on the second time - domain position as an example, the first CSI information includes indication information for indicating the first receiving unit of the terminal device, and the second CSI information includes indication information for indicating the second receiving unit of the terminal device. In this way, the network device can know that the first CSI information is the CSI information of the first receiving unit of the terminal device according to the indication information in the first CSI information, and know that the second CSI information is the CSI information of the second receiving unit of the terminal device according to the indication information in the second CSI information.

[0303]

Example illustration of a communication method

[0304] Combined with the above content, the following is an example introduction to the CSI - related configuration under multiple sub - receivers, as Figure 6 shown. Figure 6 FIG. is a schematic flowchart of another communication method according to an embodiment of the present application. This method is applied to a network device or a terminal device; the method includes the following steps:

[0305] S610. Determine the receiving unit of the terminal device corresponding to the CSI report, or determine the receiving unit of the terminal device corresponding to the measurement resource associated with the CSI report.

[0306] Wherein, the receiving unit of the terminal device is one of a receiving antenna port group of the terminal device, an antenna panel of the terminal device, or a sub - receiver of the terminal device.

[0307] It can be seen that in this embodiment, the terminal device receiving unit corresponding to the CSI report can be determined, so that different CSI reports can have their respective corresponding terminal device receiving units, or different terminal device receiving units can have their respective corresponding CSI reports. At the same time, since the CSI report is associated with measurement resources, different terminal device receiving units can determine their respective corresponding measurement resources according to their respective corresponding CSI reports. In this way, different terminal device receiving units can perform CSI measurements according to their respective measurement resources and perform their respective CSI reports after the CSI measurements are completed, so that the network can perform link adaptation and the like on different terminal device receiving units according to the CSI reports of different terminal device receiving units.

[0308] Alternatively, in this embodiment, the terminal device receiving unit corresponding to the measurement resources associated with the CSI report can be determined, so that different measurement resources can have their respective corresponding terminal device receiving units, or different terminal device receiving units can have their respective corresponding measurement resources. In this way, different terminal device receiving units can perform CSI measurements according to their respective measurement resources.

[0309] Combining the above content, some possible implementation manners will be described below. For those not described, reference can be made to the above content and will not be elaborated here.

[0310] Optionally, the terminal device receiving unit corresponding to the CSI report is indicated by the CSI report configuration information; the CSI report configuration information is used to configure the CSI report.

[0311] In this way, the CSI report can be configured through the CSI report configuration information, and the terminal device receiving unit corresponding to the CSI report can also be indicated.

[0312] Optionally, the CSI report includes a first CSI report and a second CSI report, and the first CSI report and the second CSI report are different CSI reports;

[0313] The terminal device receiving unit includes a first terminal device receiving unit corresponding to the first CSI report and a second terminal device receiving unit corresponding to the second CSI report, and the first terminal device receiving unit and the second terminal device receiving unit are different terminal device receiving units.

[0314] It can be seen that the first CSI report corresponds to the first terminal device receiving unit, and the second CSI report corresponds to the second terminal device receiving unit. In this way, the first terminal device receiving unit can perform CSI measurements according to the measurement resources associated with the first CSI report and perform a CSI report at the time domain position of the first CSI report; correspondingly, the second terminal device receiving unit can perform CSI measurements according to the measurement resources associated with the second CSI report and perform a CSI report at the time domain position of the second CSI report.

[0315] Optionally, the ID of the first CSI report is less than the ID of the second CSI report; or, the first CSI report is the first CSI report and the second CSI report is the second CSI report.

[0316] It can be seen that the CSI report with a smaller ID or the first CSI report corresponds to the first terminal device receiving unit, and the CSI report with a larger ID or the second CSI report corresponds to the second terminal device receiving unit. In this way, the first terminal device receiving unit can perform CSI measurement according to the measurement resources associated with the CSI report with a smaller ID or the first CSI report, and perform CSI reporting at the time domain position of the CSI report with a smaller ID or the first CSI report; correspondingly, the second terminal device receiving unit can perform CSI measurement according to the measurement resources associated with the CSI report with a larger ID or the second CSI report, and perform CSI reporting at the time domain position of the CSI report with a larger ID or the second CSI report.

[0317] Optionally, the first terminal device receiving unit is the first terminal device receiving unit and the second terminal device receiving unit is the second terminal device receiving unit.

[0318] In this way, the first terminal device receiving unit can perform CSI measurement according to the measurement resources associated with the first CSI report, and perform CSI reporting at the time domain position of the first CSI report; correspondingly, the second terminal device receiving unit can perform CSI measurement according to the measurement resources associated with the second CSI report, and perform CSI reporting at the time domain position of the second CSI report.

[0319] Optionally, the first CSI report and the second CSI report are respectively associated with different measurement resources, and the first CSI report is associated with the second CSI report;

[0320] The channel measurement resources associated with the second CSI report can be used for interference measurement of the first CSI report, and the channel measurement resources associated with the first CSI report can be used for interference measurement of the second CSI report.

[0321] In this way, by associating the first CSI report with the second CSI report, the first terminal device receiving unit corresponding to the first CSI report can perform interference measurement according to the channel measurement resources associated with the second CSI report; correspondingly, the second terminal device receiving unit corresponding to the second CSI report can perform interference measurement according to the channel measurement resources associated with the first CSI report.

[0322] Optionally, the association of the first CSI report with the second CSI report is indicated by the first CSI report configuration information or the second CSI report configuration information;

[0323] The first CSI report configuration information is used to configure the first CSI report, and the second CSI report configuration information is used to configure the second CSI report.

[0324] In this way, the first CSI report can be configured through the first CSI report configuration information, and it can also indicate that the first CSI report is associated with the second CSI report. Alternatively, the second CSI report can be configured through the second CSI report configuration information, and it can also indicate that the second CSI report is associated with the first CSI report.

[0325] Optionally, the first CSI report is associated with the second CSI report, including:

[0326] The association ID associated with the first CSI report is the same as the association ID associated with the second CSI report.

[0327] In this way, the association between CSI reports is realized through the association ID of the CSI reports for network configuration.

[0328] Optionally, the association ID associated with the first CSI report is indicated by the first CSI report configuration information, and the first CSI report configuration information is used to configure the first CSI report;

[0329] The association ID associated with the second CSI report is indicated by the second CSI report configuration information, and the second CSI report configuration information is used to configure the second CSI report.

[0330] In this way, the first CSI report can be configured through the first CSI report configuration information, and it can also indicate the association ID of the first CSI report, and through the second CSI report configuration information, the second CSI report can be configured and the association ID of the second CSI report can be indicated.

[0331] Optionally, the first CSI report and the second CSI report are associated with the same measurement resource.

[0332] In this way, the first terminal device receiving unit and the second terminal device receiving unit can perform CSI measurement with the same measurement resource, and then perform CSI reports at the time domain positions of the first CSI report and the second reported time domain position respectively.

[0333] Optionally, the same measurement resource includes a first channel measurement resource; the first channel measurement resource is associated with a first resource and a second resource, the first resource includes an NZP-CSI-RS resource and / or a channel state information interference measurement CSI-IM resource, and the second resource includes another NZP CSI-RS resource and / or another CSI-IM resource; the first resource corresponds to the first terminal device receiving unit, and the second resource corresponds to the second terminal device receiving unit.

[0334] In this way, the first terminal device receiving unit can perform CSI measurement based on the first measurement, and the second terminal device receiving unit can perform CSI measurement based on the first measurement.

[0335] Optionally, the terminal device receiving unit corresponding to the measurement resource associated with the CSI report is indicated by the measurement resource configuration information;

[0336] The measurement resource configuration information is used to configure the measurement resource associated with the CSI report.

[0337] In this way, the measurement resource configuration information can not only configure the measurement resource associated with the CSI report, but also indicate the terminal device receiving unit corresponding to the measurement resource associated with the CSI report.

[0338] Optionally, the measurement resources associated with the CSI report include a first measurement resource and a second measurement resource, and the first measurement resource and the second measurement resource are different measurement resources;

[0339] The terminal device receiving unit includes a first terminal device receiving unit corresponding to the first measurement resource and a second terminal device receiving unit corresponding to the second measurement resource, and the first terminal device receiving unit and the second terminal device receiving unit are different terminal device receiving units.

[0340] In this way, the first terminal device receiving unit can perform CSI measurement based on the first measurement resource, and the second terminal device receiving unit can perform CSI measurement based on the second measurement resource.

[0341] Optionally, the ID of the first measurement resource is less than the ID of the second measurement resource; and,

[0342] The first terminal device receiving unit is the first terminal device receiving unit, and the second terminal device receiving unit is the second terminal device receiving unit.

[0343] It can be seen that the measurement resource with a smaller ID corresponds to the first terminal device receiving unit, and the measurement resource with a larger ID corresponds to the second terminal device receiving unit. In this way, the first terminal device receiving unit can perform CSI measurement based on the measurement resource with a smaller ID; correspondingly, the second terminal device receiving unit can perform CSI measurement based on the measurement resource with a larger ID.

[0344] Optionally, the first measurement resource is the first measurement resource, the second measurement resource is the second measurement resource; and,

[0345] The first terminal device receiving unit is the first terminal device receiving unit, and the second terminal device receiving unit is the second terminal device receiving unit.

[0346] In this way, the first terminal device receiving unit can perform CSI measurement according to the first measurement resource; correspondingly, the second terminal device receiving unit can perform CSI measurement according to the second measurement resource.

[0347] Optionally, the first CSI information of the first terminal device receiving unit is carried on the first time domain position;

[0348] The second CSI information of the second terminal device receiving unit is carried on the second time domain position;

[0349] The first time domain position and the second time domain position are different time domain positions.

[0350] In this way, by carrying the first CSI information and the second CSI information on different time domain positions, time-division reporting is achieved.

[0351] Optionally, the first time domain position and the second time domain position are associated with the uplink time slot where the CSI report is located.

[0352] It can be seen that since the first measurement resource and the second measurement resource associated with the CSI report respectively correspond to the first terminal device receiving unit and the second terminal device receiving unit, the first CSI information of the first terminal device receiving unit and the second CSI information of the second terminal device receiving unit can be respectively carried on different time domain positions associated with the uplink time slot where the CSI report is located, thereby achieving time-division reporting.

[0353] Optionally, the first time domain position and the second time domain position are associated with the uplink time slot where the CSI report is located, including:

[0354] The first time domain position includes a first uplink time slot, and the first uplink time slot is the uplink time slot where the CSI report is located or an available uplink time slot after the uplink time slot where the CSI report is located;

[0355] The second time domain position includes a second uplink time slot, and the second uplink time slot is an available uplink time slot after the uplink time slot where the CSI report is located;

[0356] The first uplink time slot and the second uplink time slot are different available uplink time slots.

[0357] In this way, the first CSI information and the second CSI information can be carried on different available uplink time slots, and these two uplink time slots are associated with the uplink time slot where the CSI report is located, thereby achieving time-division reporting.

[0358] Optionally, the first CSI information includes indication information for indicating the first terminal device receiving unit;

[0359] The second CSI information includes indication information for indicating the second terminal device receiving unit.

[0360] In this way, the network device can learn from the indication information in the first CSI information that the first CSI information is the CSI information of the receiving unit of the first terminal device, and learn from the indication information in the second CSI information that the second CSI information is the CSI information of the receiving unit of the second terminal device.
