Technical Field

[0003] The present application relates to the field of communication technology, and in particular to a measurement reporting method, device, and system. Background Art

[0004] In a subband full-duplex (SBFD) scheme, a carrier can be divided into multiple subbands. One of two adjacent subbands can be used for uplink transmission, while the other can be used for downlink transmission. Since the signal power in one subband may leak into other adjacent subbands, this can cause interference between the uplink (UL) and downlink (DL), also known as cross-link interference (CLI).

[0005] Currently, there are no clear regulations on the methods of CLI measurement and reporting. Summary of the Invention

[0006] The embodiments of the present application provide a measurement and reporting method, apparatus, and system for CLI measurement and reporting.

[0007] To achieve the above objectives, the embodiments of the present application adopt the following technical solutions:

[0008] In a first aspect, a measurement reporting method is provided, and the apparatus for executing the measurement reporting method may be a terminal device, or may be a module applied to the terminal device, such as a chip or a chip system. That is, the method can be applied to the terminal device side. The measurement reporting method includes: receiving first configuration information, the first configuration information is used to configure one or more first-class measurement reports, the one or more first-class measurement reports are used for cross-link interference CLI measurement and reporting between terminal devices, and the one or more first-class measurement reports belong to channel state information CSI measurement reporting; according to the first configuration information, sending at least one of the one or more first-class measurement reports.

[0009] The measurement reporting method provided in the embodiments of this application clarifies the CLI measurement reporting method between terminal devices, thereby providing a basis for specific implementation on the network device side and the terminal device side. This measurement reporting method can be reused with the current CSI measurement reporting method, thereby simplifying the implementation process of CLI measurement reporting.

[0010] In combination with the above-mentioned first aspect, in a possible implementation manner, a first-type measurement report only includes CLI measurement information between terminal devices.

[0011] In combination with the first aspect above, in a possible implementation, the number of channel state information processing units (CPUs) corresponding to the first type of measurement report is greater than 0 and less than or equal to 1. For example, when the CLI measurement information only includes CLI-RSSI, the number of CPUs corresponding to the first type of measurement report may be greater than 0 and less than 1. Since the measurement of CLI-RSSI is relatively easy, when the CLI measurement information only includes CLI-RSSI, the number of CPUs corresponding to the first type of measurement report may be set to a smaller value.

[0012] In combination with the above-mentioned first aspect, in a possible implementation manner, a first-type measurement report includes both CSI measurement information and CLI measurement information between terminal devices.

[0013] In conjunction with the above-described first aspect, in one possible implementation, the number of CPUs corresponding to a first-category measurement report is greater than a first value, where the first value is the number of CPUs corresponding to a CSI measurement report that includes only the CSI measurement information. In this solution, a first-category measurement report involves not only the calculation or processing of CSI measurement information, but also the calculation or processing of CLI measurement information. Therefore, a first-category measurement report may occupy more CPUs.

[0014] In conjunction with the first aspect above, in a possible implementation, the number of CPUs corresponding to the first type of measurement report satisfies the sum of the first value and a second value, and the second value is greater than 0 and less than or equal to 1. For example, the second value may be 0.5 or 1.

[0015] In combination with the above-mentioned first aspect, in a possible implementation, the method also includes: receiving a first message; wherein the first message is used to trigger at least one of the first-type measurement reports; the time interval after the end of the last symbol occupied by the channel carrying the first message and before the start of the first symbol occupied by the channel carrying the at least one of the first-type measurement reports is a first delay; the time interval after the end of the last symbol in the measurement resource corresponding to the at least one of the first-type measurement reports and before the start of the first symbol occupied by the channel carrying the at least one of the first-type measurement reports is a second delay; the first delay and the second delay are determined according to the subcarrier spacing SCS.

[0016] In combination with the first aspect above, in a possible implementation, the CLI measurement between the terminal devices is beam-based measurement, and the first delay Z, the second delay Z', and the parameter μ used to characterize the SCS satisfy the following relationship:

[0017] Among them, X0, X1, X2, X3, X5, and X6 are determined according to the beam reporting timing capability of the terminal device, and KB1, KB2, KB3, and KB4 are determined according to the beam switching timing capability of the terminal device. In this scheme, the CLI measurement between terminal devices is a beam-based measurement. For example, the measurement resources used for CLI measurement are configured with an SRS resource set as the granularity, wherein the SRS resource set includes multiple SRS resources, and each SRS resource is associated with multiple Type D QCL relationships. Or, for example, only one SRS resource is configured, and the SRS resource is associated with multiple Type DQCL relationships. Under this condition, the value of the first delay can reuse the value of Z3 in Table 2 in the CSI measurement and reporting mechanism; the value of the second delay can reuse the value of Z′3 in Table 2 in the CSI measurement and reporting mechanism.

[0018] In combination with the above first aspect, in a possible implementation, the CLI measurement between the terminal devices is not beam-based measurement, and the first delay Z, the second delay Z', and the parameter μ used to characterize the SCS satisfy the following relationship:

[0019] Alternatively, the first time delay Z, the second time delay Z', and the parameter μ used to characterize the SCS satisfy the following relationship:

[0020] In this solution, CLI measurements between terminal devices are not beam-based. For example, only one SRS resource is configured, and this SRS resource is associated with a Type D QCL relationship. In this case, the first delay value can reuse the Z1 value in Table 1 or Table 2 of the CSI measurement and reporting mechanism; the second delay value can reuse the Z1′ value in Table 1 or Table 2 of the CSI measurement and reporting mechanism.

[0021] In combination with the above first aspect, in a possible implementation manner, the method further includes: sending first indication information; the first indication information is used to indicate the number of CPUs corresponding to the first type of measurement report.

[0022] In combination with the above-mentioned first aspect, in a possible implementation method, the CLI measurement information includes at least one of the following: sounding reference signal SRS-reference signal received power RSRP, CLI-received signal strength indication RSSI, SRS-signal to interference plus noise ratio SINR, SRS resource indication, or CLI-RSSI resource indication; wherein, SRS-RSRP is the received signal received power of SRS, the SRS resource indication is a resource indication for SRS-RSRP or SRS-SINR measurement, CLI-RSSI is the RSSI of CLI, and the CLI-RSSI resource indication is a resource indication for CLI-RSSI measurement.

[0023] In conjunction with the first aspect above, in one possible implementation, the CSI measurement information includes at least one of the following: layer L1 reference signal received power (RSRP), layer L1 signal to interference plus noise ratio (SINR), channel quality indicator (CQI), rank indicator (RI), precoding matrix indicator (PMI), layer indicator (LI), CSI-RS resource indicator (CRI), synchronization signal and physical broadcast channel block resource indicator (SSBRI), or time domain channel property (TDCP). In this solution, the CLI measurement information is different from the CSI measurement information. In other words, the CLI measurement quantity is different from the CSI measurement quantity, or the CLI reporting quantity is different from the CSI reporting quantity.

[0024] In conjunction with the first aspect above, in one possible implementation, the method further includes: sending second indication information or third indication information; wherein the second indication information is used to indicate the number of CLI and CSI measurement calculations supported simultaneously, and the third indication information is used to indicate the number of CLI measurement calculations supported simultaneously between terminal devices. In this solution, the terminal device can report its own capability information to the network device.

[0025] A second aspect provides a measurement reporting method. The apparatus performing the measurement reporting method may be a terminal device, or a module implemented in the terminal device, such as a chip or chip system. That is, the method may be applied to the terminal device. The measurement reporting method includes: performing channel state information (CSI) measurements on sub-band full-duplex (SBFD) time units to obtain measurement results; the measurement results are obtained based on cross-link interference (CLI) measurement information between the terminal devices; and sending a CSI reporting message; wherein the CSI reporting message includes the measurement results.

[0026] In the measurement reporting method provided in the embodiments of the present application, a terminal device performs CSI measurements on an SBFD time unit. The obtained measurement results take into account the CLI measurement information between terminal devices, thereby implicitly reporting the CLI measurement information to the network device. The network device can obtain CLI measurement information based on CSI reporting messages that include CLI measurement information and CSI reporting messages that only include CSI measurement information.

[0027] In combination with the above-mentioned second aspect, in a possible implementation, performing CSI measurement on the SBFD time unit includes: performing CSI measurement on a first measurement resource; the first measurement resource includes the SBDF time unit in the time domain; the first measurement resource is a time-frequency resource for performing channel measurement or interference measurement; or, the first measurement resource is a time-frequency resource dedicated to CLI measurement information between terminal devices. In this solution, the first measurement resource may be, for example, at least one of the CSI-RS resource currently used for channel measurement, the CSI-IM for interference measurement, or the NZP CSI-RS for interference measurement. Alternatively, the first measurement resource may be, for example, a CLI-RSSI measurement resource dedicated to CLI-RSSI measurement, or an SRS resource dedicated to SRS-RSRP measurement.

[0028] In combination with the above-mentioned second aspect, in a possible implementation method, the first measurement resource is a time-frequency resource used for channel measurement or interference measurement; the number of channel state information processing unit CPUs corresponding to the CSI reporting message is the same as the first value, and the first value is the number of CPUs corresponding to the CSI reporting message that only includes CSI measurement results.

[0029] In combination with the above-mentioned second aspect, in a possible implementation method, the first measurement resource is a time-frequency resource dedicated to CLI measurement information between terminal devices; the number of CPUs corresponding to the CSI reporting message is greater than a first value, and the first value is the number of CPUs corresponding to the CSI reporting message that only includes CSI measurement results. In this solution, in the process of generating a CSI reporting message, the terminal device not only needs to measure CSI on the time-frequency resources currently used for channel measurement or interference measurement, but also needs to measure CLI on the first measurement resource. Therefore, the complexity of UE generating CSI reporting messages will increase, that is, the number of CPUs corresponding to CSI reporting messages will increase.

[0030] In conjunction with the above second aspect, in a possible implementation, the number of CPUs corresponding to the CSI reporting message satisfies the sum of the first value and the second value, and the second value is greater than 0 and less than or equal to 1. Exemplarily, the second value may be 0.5 or 1.

[0031] In combination with the above-mentioned second aspect, in a possible implementation, before performing CSI measurement on the SBFD time unit, the method also includes: receiving a first message; wherein the first message is used to trigger CSI measurement on the SBFD time unit; the time interval after the end of the last symbol occupied by the channel carrying the first message to the start of the first symbol occupied by the channel carrying the measurement result is a first delay; the time interval after the end of the last symbol in the first measurement resource to the start of the first symbol occupied by the channel carrying the measurement result is a second delay; the first delay and the second delay are determined according to the subcarrier spacing SCS.

[0032] In conjunction with the above second aspect, in a possible implementation, the first time delay Z, the second time delay Z′, and the parameter μ used to characterize the SCS satisfy the following relationship:

[0033] Alternatively, the first time delay Z, the second time delay Z', and the parameter μ used to characterize the SCS satisfy the following relationship:

[0034] In this solution, the value of the first delay can reuse the value of Z1 in Table 1 or Table 2 in the CSI measurement and reporting mechanism; the value of the second delay can reuse the value of Z′1 in Table 1 or Table 2 in the CSI measurement and reporting mechanism.

[0035] In combination with the above second aspect, in a possible implementation, the method further includes: sending first indication information; the first indication information is used to indicate the number of CPUs corresponding to the CSI reporting message.

[0036] In conjunction with the above second aspect, in one possible implementation, the CSI reporting message includes a signal-to-interference-plus-noise ratio (SINR) and / or a channel quality indicator (CQI). In this solution, the CLI measurement amount is the same as the CSI measurement amount, or the CLI reporting amount is the same as the CSI reporting amount.

[0037] In a third aspect, a measurement reporting method is provided. The apparatus performing the measurement reporting method may be a terminal device, or may be a module applied to the terminal device, such as a chip or chip system. That is, the method may be applied to the terminal device side. The measurement reporting method includes: receiving configuration information from a network device; the configuration information is used to configure a first time-frequency resource for the terminal device, the first time-frequency resource not being used for uplink channel / signal transmission, and the uplink transmission may be a PUSCH or a PUCCH.

[0038] In conjunction with the third aspect above, in one possible implementation, when the first time-frequency resource overlaps with the time-frequency resource of a PUSCH, the PUSCH performs rate matching on the time-frequency resource within the first time-frequency resource that overlaps with the PUSCH's time-frequency resource. This rate matching is the process of selecting coded bits from coded bits obtained by channel coding the data carried by the PUSCH based on the available time-frequency resources of the PUSCH. This invention solution has the advantage that, since the terminal device does not transmit a PUSCH on the first time-frequency resource, the network device can perform channel or interference measurement on these time-frequency resources, which facilitates accurate channel or interference measurement by the network device. For example, the network device can measure gNB-to-gNB CLI and perform interference avoidance or suppression, thereby improving network performance.

[0039] In conjunction with the third aspect above, in one possible implementation, the first time-frequency resource includes one or more symbols in the time domain and one or more subcarriers in the frequency domain. In one possible implementation, the first time-frequency resource is comb-mapped in the frequency domain, where the comb mapping is performed on every other subcarrier or subcarriers, thereby reducing the peak-to-average power ratio (PAPR) of the terminal device.

[0040] In conjunction with the third aspect above, in one possible implementation, when the PUSCH carries uplink control information (UCI), in one possible implementation, the first time-frequency resource does not overlap with the symbols carrying the UCI in the PUSCH, or in other words, the first time-frequency resource does not include the symbols carrying the UCI in the PUSCH. In another possible implementation, when the first time-frequency resource overlaps with the symbols carrying the UCI in the PUSCH, or in other words, the first time-frequency resource includes the symbols carrying the UCI in the PUSCH, the first time-frequency resource is not used for UCI transmission. For example, the modulation symbols carrying the UCI are not mapped to the first time-frequency resource, or in other words, when determining available resource elements (REs) for UCI transmission, the first time-frequency resource is excluded, or the first time-frequency resource does not belong to the available REs for UCI information. This method has the advantage of reducing the impact of the first time-frequency resource on UCI transmission and ensuring the performance of UCI transmission.

[0041] In combination with the third aspect above, in one possible implementation, when the PUSCH is configured with a phase tracking reference signal (PT-RS), in one possible implementation, the first time-frequency resource does not overlap with the symbol carrying the PT-RS information in the PUSCH, or in other words, the first time-frequency resource does not include the symbol carrying the PT-RS in the PUSCH. In another possible implementation, the first time-frequency resource overlaps with the symbol carrying the PT-RS in the PUSCH, or in other words, the first time-frequency resource includes the symbol carrying the PT-RS in the PUSCH. When the first time-frequency resource overlaps with the RE occupied by the PT-RS, the RE in the first time-frequency resource that overlaps with the RE occupied by the PT-RS is not effective, or in other words, the first time-frequency resource is not effective for the PT-RS, and the PT-RS can be transmitted on the first time-frequency resource. The advantage of this method is that it can reduce the impact of the first time-frequency resource on the PT-RS transmission and ensure the performance of the PT-RS transmission.

[0042] In a fourth aspect, a measurement reporting method is provided, and the apparatus for executing the measurement reporting method may be a terminal device, or may be a module applied to the terminal device, such as a chip or a chip system.

[0240] In order to facilitate understanding of the technical solutions of the embodiments of the present application, a brief introduction to the relevant technologies or terms of the present application is first given as follows.

[0241] 1.SBFD.

[0242] Typically, fifth-generation (5G) new radio (NR) wireless communication systems are deployed in mid- and high-frequency bands and utilize large bandwidths to achieve high data rates and low latency. In time division duplexing (TDD) systems, as shown in Figure 1, the downlink (DL) typically occupies the majority of time resources, resulting in an imbalance in coverage between the DL and uplink (UL). Compared to frequency division duplexing (FDD) systems, TDD systems have poor uplink coverage, resulting in longer uplink latency.

[0243] To address the uplink coverage and latency issues in TDD systems, the SBFD solution was proposed in Release (R) 18. In the SBFD solution, a carrier can be divided into multiple subbands, and the transmission directions of different subbands can be different.

[0244] For example, Figure 2 shows a schematic diagram of time-frequency resource allocation in an SBFD scheme. In the three middle time units, a carrier can be divided into three subbands. The middle subband is the uplink subband used for uplink transmission, labeled UL in the figure. The upper and lower subbands are downlink subbands used for downlink transmission, labeled DL in the figure.

[0245] The upper subband refers to a higher-frequency subband, the lower subband refers to a lower-frequency subband, and the middle subband refers to a subband with a frequency between the upper and lower subbands. The first or last time unit can be referred to as a non-SBFD time unit, and any time unit in between can be referred to as an SBFD time unit. A time unit can be, for example, a time slot or a symbol.

[0246] For example, Figure 3 shows a schematic diagram of time-frequency resource allocation in an SBFD scheme. In the three time units in the middle, a carrier can be divided into two subbands. The upper subband is the downlink subband used for downlink transmission, labeled DL in the figure. The lower subband is the uplink subband used for uplink transmission, labeled UL in the figure.

[0247] It can be considered that in the SBFD scheme, network devices can simultaneously transmit and receive signals using different frequency resources, or sub-bands, within an SBFD time unit. Currently, the Release 19 standard allows network devices to use sub-band full-duplex, while terminal devices can use sub-band half-duplex. When a terminal device uses sub-band half-duplex, it can only receive or transmit signals within an SBFD time unit, not simultaneously.

[0248] Compared to TDD systems, SBFD increases the uplink transmission resources available to terminal devices, effectively improving uplink coverage and reducing uplink latency.

[0249] 2.CLI.

[0250] In the SBFD scheme, signal power in one subband leaks into adjacent subbands, causing interference between the UL and DL, or CLI. Depending on the source of interference, CLI can be divided into the following two types:

[0251] 1) Type 1: CLI between user equipment (UE) and UE (UE-to-UE CLI).

[0252] UE-to-UE CLI refers to the interference caused by uplink signals transmitted by a UE in a local cell on the downlink signals received by another UE in the local cell or a neighboring cell. For example, in Figure 4, the interference caused by uplink signals transmitted by UE#1 or UE#2 to gNB#1 on the downlink signals received by UE#0 from gNB#0 is called UE-to-UE CLI. This embodiment of the present application primarily measures and reports UE-to-UE CLI.

[0253] 2) Type 2: gNB-to-gNB CLI (gNB-to-gNB CLI).

[0254] gNB-to-gNB CLI refers to the interference caused by downlink signals transmitted by one base station on uplink signals received by another base station. For example, in Figure 4, the interference caused by downlink signals transmitted by gNB#0 to UE#0 on uplink signals received by gNB#1 from UE#1 or UE#2 is called gNB-to-gNB CLI.

[0255] 3.UE-to-UE CLI measurement and reporting mechanism.

[0256] In the UE-to-UE CLI measurement and reporting mechanism, a UE transmits a sounding reference signal (SRS) to the gNB on which it resides. Another UE residing in its own cell or a neighboring cell measures the SRS and reports the measurement results to the serving cell of the other UE. As shown in Figure 4, UE#1 can transmit an SRS to gNB#1. UE#0 can measure the SRS transmitted by UE#1 and send the measurement results to gNB#0; alternatively, UE#2 can measure the SRS transmitted by UE#1 and send the measurement results to gNB#1. Measurement metrics can include SRS (reference signal receiving power) and / or CLI (received signal strength indication).

[0257] For dynamic TDD systems, the Release 16 standard defines a Layer 3 (L) 3 UE-to-UE CLI (hereinafter referred to as "L3 UE-to-UE CLI") measurement and reporting mechanism. The L3 UE-to-UE CLI measurement and reporting mechanism refers to UE-to-UE CLI measurements and reporting performed at the radio resource control (RRC) protocol layer. For example, RRC signaling can trigger UE-to-UE CLI measurements, and RRC signaling can be used to report measurement results.

[0258] For the SBFD solution, the R19 standard introduces a L1 or L2 level UE-to-UE CLI (hereinafter referred to as "L1 / L2 UE-to-UE CLI") measurement and reporting mechanism. The measurement and reporting mechanism refers to the UE-to-UE CLI measurement and reporting performed at the physical layer or data link layer level. For example, downlink control information (DCI) or MAC control element (CE) can trigger UE-to-UE CLI measurement, and the measurement results are reported through the uplink physical shared channel (PUSCH) and / or uplink physical control channel (PUCCH). Compared with the L3 UE-to-UE CLI measurement and reporting mechanism, the L1 / L2 UE-to-UE CLI measurement and reporting mechanism is more flexible and has a shorter measurement and reporting delay, which can better track UE-to-UE CLI changes, making the measurement results more accurate, and thus helping to better eliminate UE-to-UE CLI.

[0259] Furthermore, the Release 19 standard also mentions the reuse of the L1 / L2 UE-to-UE CLI measurement and reporting mechanism with the existing CSI measurement and reporting mechanism. CSI measurement is primarily used for channel and interference measurements between the UE and gNB.

[0260] 4. The UE processing capability defined in the CSI measurement and reporting mechanism.

[0261] Typically, the processing capability of a UE refers to the number N of simultaneous CSI calculations that the UE can perform within a component carrier (CC) and across all CCs. CPU UE supports N CPU CSI calculations performed simultaneously can also be understood as the UE having N CPUA CSI processing unit (CPU) for processing CSI reports. The UE can report its processing capabilities to the gNB.

[0262] If a UE has L CPUs occupied for CSI reporting processing in an OFDM symbol, the UE has N CPUs in the OFDM symbol. CPU -L unoccupied CPUs. If N CSI reports are required to occupy their own CPUs on the same OFDM symbol, and there are N CPU -L unoccupied CPUs, where each CSI reporting information corresponds to CPUs, n = 0, ..., N-1, then the UE does not need to update the CSI reporting information of the NM lowest priority requests, or in other words, the UE only needs to update the CSI reporting information of the M highest priority requests, where 0 ≤ M ≤ N, M is the number of requests that meet The maximum value of .

[0263] For a certain UE, the number of CPUs occupied by it in processing a CSI report in some OFDM symbols is O CPU It is related to the reporting amount contained in the CSI reporting information, and is specifically divided into the following situations:

[0264] 1) Case 1, O CPU =0.

[0265] The value condition is: the reporting amount included in the CSI reporting information is set to 'none', and the CSI-reference signal (RS) resource set (resource set) associated with the CSI reporting information is configured with tracking reference signal (trs)-information (info).

[0266] 2) Case 2, O CPU =1.

[0267] The value condition is: the reporting amount contained in the CSI reporting information is set to 'CSI-RS resource indicator (cri)-reference signal receiving power (RSRP)', 'synchronization signal and physical broadcast channel block (ssb)-index (Index)-RSRP', 'cri-signal to interference plus noise ratio (SINR)', 'ssb-Index-SINR', 'cri-RSRP-Index', 'ssb-Index-RSRP-Index', 'cri-SINR-Index' or 'ssb-Index-SINR-Index'. Alternatively, the reporting amount contained in the CSI reporting information is set to 'none', and the CSI-RS resource set associated with the CSI reporting information is not configured with trs-info.

[0268] 3) Case 3, O CPU =N CPU .

[0269] The conditions for taking the value are: under the premise of satisfying the first condition, satisfying max{μ PDCCH ,μ CSI-RS ,μ UL}≤3, and the CSI report message is non-periodically triggered, and there is neither transport block (TB) nor hybrid automatic repeat request (HARQ)-acknowledgement (ACK) transmission, and L=0 CPUs are occupied, and the CSI report message corresponds to one CSI and the CSI is of wideband granularity, and there are at most 4 CSI-RS ports in one CSI-RS resource, and the codebook type is set to 'Type I - Single Panel' or the reporting amount is set to 'cri-RI-CQI'.

[0270] Among them, μ PDCCH Used to characterize the subcarrier spacing (SCS) of PDCCH, μ CSI-RS SCS used to characterize CSI-RS, μ UL Used to indicate the subcarrier spacing of UL.

[0271] Among them, the first condition is that the reporting amount contained in the CSI reporting information is set to 'cri-rank indication (RI)-precoding matrix indicator (PMI)-channel quality indicator (CQI)', 'cri-RI-i1 (wideband indication)', 'cri-RI-i1-CQI', 'cri-RI-CQI' or 'cri-RI-layer indication (LI)-PMI-CQI'.

[0272] 4) Case 4, O CPU =X·N+M′.

[0273] The conditions for taking the value are: Under the premise of meeting the first condition above, the codebook type is set to 'typeI-SinglePanel', and the corresponding CSI-RS resource set for channel measurement is configured with two resource groups and N resource pairs. Where X is the number of CPUs occupied by a pair of channel measurement resources (CMRs), and M' is predefined.

[0274] 5) Case 5, O CPU =K s Among them, K s is the number of CSI-RS resources in the CSI-RS resource set used for channel measurement.

[0275] The conditions for taking the value are: on the premise of meeting the first condition above, meeting other conditions other than the conditions described in Case 3 and Case 4.

[0276] As mentioned above, a CSI reporting message whose reporting amount is not set to 'none' occupies CPU on some OFDM symbols. The following describes the meaning of "some OFDM" in different situations.

[0277] A periodic or semi-persistent CSI reporting message occupies the CPU from the first symbol of the earliest CSI-RS / CSI-IM / SSB among all CSI-RS / CSI-interference measurement (IM) / SSBs used for channel or interference measurement to the last symbol of the PUSCH / PUCCH carrying the periodic or semi-persistent CSI reporting message. The semi-persistent CSI reporting message does not include the initial semi-persistent CSI reporting message carried on the PUSCH after the PDCCH that triggers the measurement report.

[0278] An aperiodic CSI (A-CSI) reporting message occupies the CPU from the first symbol after the PDCCH that triggers the aperiodic CSI reporting message to the last symbol of the scheduled PUSCH that carries the aperiodic CSI reporting message.

[0279] An initial semi-persistent CSI reporting message carried on the PUSCH after the PDCCH that triggers the measurement report occupies the CPU from the first symbol after the PDCCH to the last symbol of the scheduled PUSCH carrying the initial semi-persistent CSI reporting message.

[0280] 5. The minimum processing delay of the UE defined in the CSI measurement and reporting mechanism.

[0281] Currently, a minimum processing delay (Z, Z') is defined for PDCCH-triggered aperiodic CSI or semi-persistent CSI reporting messages carried on the PUSCH. As shown in Figure 5, the PDCCH can trigger A-CSI measurement reporting, and the UE can measure CSI on CSI measurement resources. The A-CSI reporting message can then be carried on uplink channels, such as the PUSCH. The PDCCH and CSI measurement resources can occupy downlink resources, while uplink channels can occupy uplink resources.

[0282] In Figure 5, Z is the minimum time interval between the end of the last PDCCH symbol and the beginning of the first PUSCH symbol. Z' is the minimum time interval between the end of the last symbol of the latest of the CSI-RS resources used for channel measurement, the CSI-IM used for interference measurement, and the (none zero power, NZP) CSI-RS used for interference measurement and the beginning of the first PUSCH symbol.

[0283] also, and Where M is the number of CSI reporting messages to be updated. The candidate values ​​for Z and Z' can be as shown in Tables 1 and 2. The subscripts 1, 2, or 3 for Z and Z' respectively indicate the first, second, or third candidate values. μ is used to characterize the SCS.

[0286] X0, X1, X2, X3, X5, and X6 are determined based on the UE's beam reporting timing capability, and KB1, KB2, KB3, and KB4 are determined based on the UE's beam switching timing capability. The UE can report its beam reporting timing capability and beam switching timing capability to the gNB.

[0287] To address the problem that there is currently no CLI measurement reporting method, the embodiments of the present application provide different CLI measurement reporting methods, and their corresponding CPU usage and minimum processing delay.

[0288] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. In the description of the present application, unless otherwise specified, " / " indicates that the objects associated before and after are in an "or" relationship. For example, A / B can represent A or B; "and / or" in the present application is only a description of the association relationship of the associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone, where A and B can be singular or plural. In addition, in the description of the present application, unless otherwise specified, "multiple" refers to two or more than two. "At least one of the following" or similar expressions refers to any combination of these items, including any combination of single or plural items. For example, at least one of a, b, or c can represent: a, b, c, ab, ac, bc, or abc, where a, b, c can be single or multiple. In addition, in order to facilitate the clear description of the technical solutions in the embodiments of the present application,

[0289] Before introducing the solution of this application, the following points are explained.

[0290] (1) In this application, “indication” may include direct indication, indirect indication, explicit indication, and implicit indication. When describing that a certain indication information is used to indicate A, it can be understood that the indication information carries A, directly indicates A, or indirectly indicates A.

[0291] In this application, the information indicated by the indication information is referred to as the information to be indicated. In the specific implementation process, there are many ways to indicate the information to be indicated, such as but not limited to, the information to be indicated can be directly indicated, such as the information to be indicated itself or the index of the information to be indicated. The information to be indicated can also be indirectly indicated by indicating other information, wherein there is an association between the other information and the information to be indicated. It is also possible to indicate only a part of the information to be indicated, while the other parts of the information to be indicated are known or agreed in advance. For example, the indication of specific information can also be achieved with the help of the arrangement order of each information agreed in advance (for example, stipulated by the protocol), thereby reducing the indication overhead to a certain extent. In addition, the information to be indicated can be sent together as a whole, or it can be divided into multiple sub-information and sent separately, and the sending period and / or sending time of these sub-information can be the same or different.

[0292] (2) In this application, “sending” and “receiving” refer to the direction of signal transmission. For example, “sending information to XX” can be understood as the destination of the information being XX, which can include direct sending through the air interface, as well as indirect sending through the air interface by other units or modules. “Receiving information from YY” can be understood as the source of the information being YY, which can include direct receiving from YY through the air interface, as well as indirect receiving from YY through the air interface from other units or modules. “Sending” can also be understood as the “output” of the chip interface, and “receiving” can also be understood as the “input” of the chip interface. In other words, sending and receiving can be performed between devices, for example, between a network device and a terminal device, or can be performed within a device, for example, between components, modules, chips, software modules, or hardware modules within the device through a bus, a line, or an interface. In addition, unless otherwise specified, “transmitting” includes receiving and / or sending. For example, transmitting a signal can include receiving a signal and / or sending a signal.

[0293] (3) In this application, information C is used to determine information D, which includes both information D being determined solely based on information C and information D being determined based on information C and other information. Furthermore, information C can also be used to determine information D indirectly, for example, when information D is determined based on information E, and information E is determined based on information C.

[0294] (4) The terms "comprise," "include," and "have," and any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus that includes a series of steps or elements is not necessarily limited to those steps or elements expressly listed but may include other steps or elements not expressly listed or inherent to the process, method, product, or apparatus.

[0295] (5) In the various embodiments of the present application, unless otherwise specified or there is a logical conflict, the terms and / or descriptions between different embodiments are consistent and can be referenced by each other. The technical features in different embodiments can be combined to form new embodiments according to their inherent logical relationships.

[0296] (6) In this application, the terms "first" and "second" are used for convenience of description only and are not intended to limit the scope of the embodiments of this application. They are not used to describe the order or precedence of features. It should be understood that the terms described in this manner may be interchangeable, where appropriate, to describe solutions other than the embodiments of this application.

[0297] (7) In the present application, a carrier range may include at least a downlink subband and an uplink subband. The present embodiment does not impose any restrictions on whether a guard band exists between the downlink subband and the uplink subband, and if so, whether transmission can be performed on the guard band. Furthermore, the present embodiment does not impose any restrictions on whether the downlink subband and the uplink subband can overlap.

[0298] For the time domain configuration of SBFD, there are two possible configuration methods depending on whether a time slot contains both SBFD symbols and non-SBFD symbols. In one possible configuration method, the time domain configuration of SBFD is at the time slot level, that is, the symbols contained in a time slot are either all configured as SBFD symbols or all configured as non-SBFD symbols. In another possible configuration method, the time domain configuration of SBFD is at the symbol level, that is, a part of the symbols contained in a time slot can be configured as SBFD symbols, and the other part can be configured as non-SBFD symbols. The embodiment of the present application does not impose any limitation on the time domain configuration method of SBFD. Among them, SBFD symbols can be symbols configured with SBFD operations, and non-SBFD symbols can be symbols without SBFD operations. For uplink transmission, non-SBFD symbols can be uplink symbols or flexible symbols; for downlink transmission, non-SBFD symbols can be downlink symbols or flexible symbols.

[0299] The architectural diagram of the mobile communication system shown in FIG6 is a schematic diagram of the architecture of a communication system 1000 used in an embodiment of the present application. As shown in FIG6 , the communication system includes a radio access network 100 and a core network 200. Optionally, the communication system 1000 may also include the Internet 300. The radio access network 100 may include at least one radio access network device (such as 110a and 110b in FIG6 ) and at least one terminal device (such as 120a-120j in FIG6 ). The terminal device is connected to the radio access network device wirelessly, for example, via an air interface. The radio access network device is connected to the core network via wireless or wired communication. The core network device and the radio access network device may be independent and distinct physical devices, or the functions of the core network device and the logical functions of the radio access network device may be integrated into the same physical device, or a single physical device may integrate some of the functions of the core network device and some of the functions of the radio access network device. Terminal devices and radio access network devices may be connected to each other via wired or wireless communication. FIG6 is only a schematic diagram. The communication system may further include other network devices, such as wireless relay devices and wireless backhaul devices, which are not shown in FIG6 .

[0300] Radio access network equipment is the access device that terminal devices use to access the communication system wirelessly. Radio access network equipment can be a base station, an evolved NodeB (eNodeB), a transmission reception point (TRP), a gNB in ​​a 5G mobile communication system, a next-generation base station in a 6G mobile communication system, a base station in a future mobile communication system, or an access node in a WiFi system. In another possible scenario, multiple radio access network (RAN) nodes collaborate to assist the terminal in achieving wireless access, and different RAN nodes respectively implement part of the functions of the base station. For example, a RAN node can be a centralized unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU). The CU and DU can be set up separately, or they can be included in the same network element, such as the baseband unit (BBU). The RU may be included in a radio frequency device or a radio frequency unit, for example, in a remote radio unit (RRU), an active antenna unit (AAU) or a remote radio head (RRH).

[0301] In different systems, CU (or CU-CP and CU-UP), DU or RU may also have different names, but those skilled in the art can understand their meanings. For example, in an open RAN (ORAN) system, CU may also be called O-CU (open CU), DU may also be called O-DU, CU-CP may also be called O-CU-CP, CU-UP may also be called O-CU-UP, and RU may also be called O-RU. For the convenience of description, this application uses CU, CU-CP, CU-UP, DU and RU as examples for description. Any unit of CU (or CU-CP, CU-UP), DU and RU in this application may be implemented by a software module, a hardware module, or a combination of a software module and a hardware module. The embodiments of the present application may be implemented by a DU or a RU.

[0302] The wireless access network device can be a macro base station (such as 110a in Figure 6), a micro base station or an indoor station (such as 110b in Figure 6), a relay node, a donor node, etc. The embodiments of this application do not limit the specific technology and device form used by the wireless access network device. For ease of description, the following description uses a base station as an example of a wireless access network device.

[0303] The terminal device also has wireless transceiver functions and can send signals to the base station or receive signals from the base station. The terminal device can also be called a terminal, user equipment (UE), mobile station, mobile terminal device, etc. The terminal device can be widely used in various scenarios, such as environmental IoT, device-to-device (D2D), vehicle-to-everything (V2X) communication, machine-type communication (MTC), virtual reality, augmented reality, industrial control, autonomous driving, telemedicine, smart grid, smart furniture, smart office, smart wearable, smart transportation, smart city, etc. The terminal device can be a mobile phone, tablet computer, computer with wireless transceiver function, wearable device, vehicle, drone, helicopter, airplane, ship, robot, robotic arm, smart home device, etc. The embodiments of this application do not limit the specific technology and specific device form adopted by the terminal device.

[0304] Base stations and terminal devices can be fixed or mobile. They can be deployed on land, indoors or outdoors, handheld or vehicle-mounted; on water; or on aircraft, balloons, and satellites. The embodiments of this application do not limit the application scenarios of base stations and terminal devices.

[0305] The roles of base stations and terminal devices can be relative. For example, the helicopter or drone 120i in Figure 6 can be configured as a mobile base station. For terminal devices 120j accessing the wireless access network 100 via 120i, terminal device 120i is a base station. However, for base station 110a, 120i is a terminal device, meaning that communication between 110a and 120i occurs via a wireless air interface protocol. Of course, communication between 110a and 120i can also occur via a base station-to-base station interface protocol. In this case, 120i is also a base station relative to 110a. Therefore, base stations and terminal devices can be collectively referred to as communication devices. 110a and 110b in Figure 6 can be referred to as communication devices with base station functionality, while 120a-120j in Figure 6 can be referred to as communication devices with terminal functionality.

[0306] Communication between base stations and terminal devices, between base stations, and between terminal devices can be carried out through authorized spectrum, unauthorized spectrum, or both; communication can be carried out through spectrum below 6 gigahertz (GHz), spectrum above 6 GHz, or spectrum below 6 GHz and spectrum above 6 GHz. The embodiments of the present application do not limit the spectrum resources used for wireless communication.

[0307] In the embodiments of the present application, the functions of the base station may also be performed by a module (such as a chip) in the base station, or by a control subsystem that includes the base station functions. The control subsystem that includes the base station functions here may be a control center in the above-mentioned application scenarios such as smart grid, industrial control, smart transportation, and smart city. The functions of the terminal device may also be performed by a module (such as a chip or a modem) in the terminal device, or by a device that includes the terminal device functions.

[0308] Exemplarily, the network device provided in the embodiment of the present application may be, for example, 110a or 110b in FIG. 6 , and the terminal device provided in the embodiment of the present application may be, for example, any one of 120a - 120j in FIG. 6 .

[0309] The relevant functions of the network device or terminal device involved in this application can be implemented by one device, or by multiple devices together, or by one or more functional modules within a device, or by one or more chips, or by a system on chip (SOC) or a chip system. The chip system can be composed of chips, or can include chips and other discrete devices. The embodiments of this application do not specifically limit this.

[0310] It is understandable that the above functions can be network elements in hardware devices, software functions running on dedicated hardware, or a combination of hardware and software, or virtualized functions instantiated on a platform (e.g., a cloud platform).

[0311] For example, the relevant functions of the network device or terminal device in the embodiment of the present application can be implemented by the communication device 110 in Figure 7.

[0312] Figure 7 shows a schematic diagram of the structure of a possible communication device 110. It is understandable that the communication device 110 includes necessary forms of means such as modules, units, elements, circuits, or interfaces, which are appropriately configured together to implement the present solution. The communication device 110 can be a network device or a terminal device, or a component (such as a chip) in these devices, used to implement the method described in the following method embodiment. The communication device 110 includes one or more processors 111. The processor 111 can be a general-purpose processor or a dedicated processor, etc. For example, it can be a baseband processor or a central processing unit. The baseband processor can be used to process communication protocols and communication data, and the central processing unit can be used to control the communication device (such as a network device, terminal device, or chip, etc.), execute software programs, and process data of software programs.

[0313] Optionally, in one design, the processor 111 may include a program 113 (sometimes also referred to as code or instructions), which may be executed on the processor 111 to cause the communication device 110 to perform the methods described in the following embodiments. In yet another possible design, the communication device 110 includes circuitry (not shown in FIG7 ).

[0314] Optionally, the communication device 110 may include one or more memories 112 on which a program 114 (sometimes also referred to as code or instructions) is stored. The program 114 can be run on the processor 111 so that the communication device 110 performs the method described in the following method embodiment.

[0315] Optionally, the processor 111 and / or the memory 112 may include AI modules 117 and 118, which are used to implement AI-related functions. The AI ​​module may be implemented through software, hardware, or a combination of software and hardware. For example, the AI ​​module may include a RAN intelligence controller (RIC) module. For example, the AI ​​module may be a near real-time RIC or a non-real-time RIC.

[0316] Optionally, data may be stored in the processor 111 and / or the memory 112. The processor and the memory may be provided separately or integrated together.

[0317] Optionally, the communication device 110 may further include a transceiver 115 and / or an antenna 116. The processor 111 may also be referred to as a processing unit, and controls the communication device (e.g., a network device or a terminal device). The transceiver 115 may also be referred to as a transceiver unit, a transceiver, a transceiver circuit, or a transceiver, and is configured to implement the transceiver function of the communication device via the antenna 116.

[0318] In addition, the composition structure shown in FIG7 does not constitute a limitation on the communication device. In addition to the components shown in FIG7 , the communication device may include more or fewer components than shown, or combine certain components, or arrange the components differently.

[0319] The measurement reporting method provided in the embodiment of the present application will be described in detail below with reference to FIG. 1 to FIG. 7 .

[0320] FIG8 shows a flow chart of a measurement reporting method provided in an embodiment of the present application, including the following steps:

[0321] Step S801: The network device sends first configuration information to the terminal device. Correspondingly, the terminal device receives the first configuration information from the network device.

[0322] The first configuration information is used to configure one or more first-category measurement reports, one or more first-category measurement reports are used for CLI measurement and reporting between terminal devices, and one or more first-category measurement reports belong to CSI measurement reports.

[0323] In the embodiment of the present application, a CSI measurement report (a CSI report) is a measurement report corresponding to a "CSI report configuration CSI-ReportConfig" field configured by a higher layer. A CSI measurement report is related to the process of the CSI measurement report process. A CSI measurement report may correspond to one or more CSI measurement reports, or a CSI measurement report may include measurement results associated with one or more CSI measurement reports. In other words, the first configuration information may be used to configure a CSI measurement report, and a CSI measurement report includes one or more CSI measurement reports.

[0324] The "CLI between terminal devices" in the embodiment of the present application can be the aforementioned "UE-to-UE CLI".

[0325] Exemplarily, the measurement reporting method provided in the embodiments of the present application may be applied to a L1 / L2 UE-to-UE CLI measurement and reporting mechanism.

[0326] Step S802: The terminal device sends at least one of the one or more first-type measurement reports to the network device according to the first configuration information. Correspondingly, the network device receives at least one of the one or more first-type measurement reports from the terminal device.

[0327] The measurement reporting method provided in the embodiments of this application clarifies the CLI measurement reporting method between terminal devices, thereby providing a basis for specific implementation on the network device side and the terminal device side. This measurement reporting method can be reused with the current CSI measurement reporting method, thereby simplifying the implementation process of CLI measurement reporting.

[0328] In an embodiment of the present application, a first terminal device may measure an SRS from a second terminal device and send the measurement result to the serving cell of the first terminal device. The first terminal device may be the terminal device in the embodiment shown in FIG8 . Alternatively, the terminal device may perform CLI measurements between terminal devices in an SBFD time unit and send the measurement result to the network device.

[0329] In an embodiment of the present application, a first type of measurement report includes CLI measurement information between terminal devices. The CLI measurement information includes at least one of the following: SRS-RSRP, CLI-RSSI, SRS-SINR, SRS resource indicator, and CLI-RSSI resource indicator. SRS-RSRP is the received signal received power of SRS, the SRS resource indicator is a resource indicator for SRS-RSRP or SRS-SINR measurement, CLI-RSSI is the RSSI of CLI, and the CLI-RSSI resource indicator is a resource indicator for CLI-RSSI measurement.

[0330] In the embodiment shown in Figure 8, the CLI measurement information is different from the CSI measurement information. In other words, the measurement amount of CLI is different from the measurement amount of CSI, or the reported amount of CLI is different from the reported amount of CSI. Among them, the CSI measurement information includes at least one of the following: L1-RSRP, L1-SINR, CQI, RI, PMI, LI CRI, SSB resource indicator (SSBRI), or time domain channel properties (TDCP). The way in which the terminal device sends the first type of measurement report to the network device in the embodiment shown in Figure 8 can also be called explicit reporting.

[0331] The following describes two possible implementations based on whether a first-category measurement report includes CSI measurement information.

[0332] In a possible implementation, a first-category measurement report only includes CLI measurement information between terminal devices.

[0333] In this implementation, the number of CPUs corresponding to one first-category measurement report is greater than 0 and less than or equal to 1.

[0334] In the embodiment of the present application, if the number of CPUs corresponding to a first-class measurement report is set too large, some CPUs may not be actually occupied, thereby reducing CPU utilization and wasting processing resources. Conversely, if the number of CPUs corresponding to a first-class measurement report is set too small, the first-class measurement report may not be performed normally. Therefore, it is desirable to set the number of CPUs corresponding to a first-class measurement report close to the number of CPUs actually occupied by the first-class measurement report.

[0335] Illustratively, the number of CPUs corresponding to one first-category measurement report may be 1.

[0336] For example, when the CLI measurement information includes only the CLI-RSSI, the number of CPUs corresponding to one first-category measurement report may be greater than 0 and less than 1. Since CLI-RSSI measurement is relatively easy, when the CLI measurement information includes only the CLI-RSSI, the number of CPUs corresponding to one first-category measurement report may be set to a smaller value.

[0337] In another possible implementation, a first-category measurement report includes both CSI measurement information and CLI measurement information between terminal devices. For example, a first-category measurement report includes at least one of CQI and L1-SINR and at least one of SRS-RSRP, CLI-RSSI, and SRS-SINR.

[0338] In this implementation, the number of CPUs corresponding to a first type of measurement report is greater than a first value, and the first value is the number of CPUs corresponding to a CSI measurement report including only CSI measurement information. The first value may be defined in the aforementioned CSI measurement and reporting mechanism. CPU In this solution, a first-category measurement report involves not only the calculation or processing of CSI measurement information, but also the calculation or processing of CLI measurement information. Therefore, a first-category measurement report will occupy more CPU.

[0339] Optionally, the number of CPUs corresponding to a first-type measurement report satisfies the sum of a first value and a second value, and the second value is greater than 0 and less than or equal to 1.

[0340] Exemplarily, the second value may be 0.5 or 1.

[0341] Optionally, the number of CPUs corresponding to a first-type measurement report may be the sum of the number of CPUs occupied by calculating or processing CSI measurement information and the number of CPUs occupied by calculating or processing CLI measurement information.

[0342] Optionally, for a first-category measurement report, the duration of the CPU usage is as follows:

[0343] If the first type of measurement report is a periodic or semi-continuous CSI report (excluding the first semi-continuous CSI report performed on the PUSCH after the PDCCH that triggers the first type of measurement report), the CPU is occupied from the first symbol of the earliest measurement resource among all CSI-RS / CSI-IM / SSB / SRS / CLI-RSSI measurement resources used for channel or interference measurement to the last symbol of the PUSCH / PUCCH carrying the first type of measurement report.

[0344] If the first type of measurement report is an aperiodic CSI report, the CPU is occupied from the first symbol after the first type of measurement report is triggered to the last symbol of the scheduled PUSCH carrying the first type of measurement report.

[0345] If the first type of measurement report is the first semi-persistent CSI report performed on the PUSCH after the first type of measurement report is triggered, the CPU is occupied from the first symbol after the PDCCH to the last symbol of the scheduled PUSCH carrying the first type of measurement report.

[0346] With respect to the two possible implementations described above, the measurement reporting method provided in an embodiment of the present application further includes: the terminal device sending first indication information to the network device. Accordingly, the network device receives the first indication information from the terminal device. The first indication information is used to indicate the number of CPUs corresponding to a first-category measurement report.

[0347] Optionally, the measurement reporting method provided in an embodiment of the present application further includes: the terminal device sends second indication information or third indication information to the network device. Accordingly, the network device receives the second indication information or third indication information from the terminal device. The second indication information is used to indicate the number of calculations supported for simultaneous CLI measurements and CSI measurements, and the third indication information is used to indicate the number of calculations supported for simultaneous CLI measurements between terminal devices. In this solution, the terminal device can report its own capability information to the network device.

[0348] The second indication information is used to indicate the number of calculations supporting simultaneous CLI measurements and CSI measurements, which can also be expressed as the second indication information is used to indicate the number of CPUs supporting the calculation of CLI measurement information and CSI measurement information. Similarly, the third indication information is used to indicate the number of calculations supporting simultaneous CLI measurements between terminal devices, which can also be expressed as the third indication information is used to indicate the number of CPUs supporting the calculation of CLI measurement information.

[0349] When the terminal device sends the second instruction information to the network device, the aforementioned N CPU In the embodiment of the present application, a CPU or calculation can be shared by CLI measurement and CSI measurement, thereby achieving the technical effect of saving processing resources.

[0350] When the terminal device sends the third instruction information to the network device, the aforementioned N CPU In this embodiment of the application, N CPUs or computers are still dedicated to CSI measurement. C ' PU A CPU or calculation can be dedicated to CLI measurement, thereby ensuring sufficient processing resources dedicated to CLI measurement, which is conducive to ensuring the normal reporting of CLI measurement. Similarly, it can also ensure that CLI measurement does not occupy the CPU resources of CSI measurement, reducing the impact on CSI measurement. It should be noted that the aforementioned N CPU One of the CPUs and N C ' PU One of the CPUs can be the same or different, and the present invention does not limit this. By extension, when the terminal device sends the third indication information to the network device, when the terminal device determines the M CSI reporting messages with higher priorities to be updated or processed on the current symbol, the total number of CPUs occupied by the P CSI reporting messages related to the CSI does not exceed the number of CPUs available for the current CSI, and the total number of CPUs occupied by the Q CSI reporting messages related to the CLI does not exceed the number of CPUs available for the current CLI. Wherein, P+Q=M.

[0351] Optionally, the measurement reporting method provided in the embodiment of the present application also includes: the network device sends a first message to the terminal device. Correspondingly, the terminal device receives the first message from the network device. The first message is used to trigger at least one first-class measurement report. The time interval after the end of the last symbol occupied by the channel carrying the first message and before the start of the first symbol occupied by the channel carrying at least one first-class measurement report is the first delay; the time interval after the end of the last symbol in the measurement resource corresponding to at least one first-class measurement report and before the start of the first symbol occupied by the channel carrying at least one first-class measurement report is the second delay; the first delay and the second delay are determined according to the SCS.

[0352] In a possible implementation, the CLI measurement between terminal devices is beam-based measurement, and the relationship between the first delay Z, the second delay Z', and the parameter μ used to characterize the SCS is shown in Table 3.

[0353] Table 3

[0354] Among them, X0, X1, X2, X3, X5, and X6 are determined according to the beam reporting timing capability of the terminal device, and KB1, KB2, KB3, and KB4 are determined according to the beam switching timing capability of the terminal device. In this scheme, the CLI measurement between terminal devices is a beam-based measurement. For example, the measurement resources used for CLI measurement are configured with an SRS resource set as the granularity, where the SRS resource set includes multiple SRS resources. Or, for example, only one SRS resource is configured, and the SRS resource is associated with multiple Type D QCL relationships. Under this condition, the value of the first delay can reuse the value of Z3 in Table 2 in the CSI measurement and reporting mechanism; the value of the second delay can reuse the value of Z′3 in Table 2 in the CSI measurement and reporting mechanism.

[0355] In another possible implementation, the CLI measurement between terminal devices is not beam-based measurement, and the relationship between the first delay Z, the second delay Z', and the parameter μ used to characterize the SCS is shown in Table 4.

[0356] Table 4

[0357] Alternatively, the relationship between the first delay Z, the second delay Z' and the parameter μ used to characterize the SCS is shown in Table 5.

[0358] Table 5

[0359] In this solution, CLI measurements between terminal devices are not beam-based. For example, only one SRS resource is configured, and this SRS resource is associated with a Type D QCL relationship. In this case, the first delay value can reuse the Z1 value in Table 1 or Table 2 of the CSI measurement and reporting mechanism; the second delay value can reuse the Z1′ value in Table 1 or Table 2 of the CSI measurement and reporting mechanism.

[0360] FIG9 shows a flowchart of another measurement reporting method provided in an embodiment of the present application, including the following steps:

[0361] Step S901: The terminal device performs CSI measurement in the SBFD time unit to obtain a measurement result; the measurement result is obtained based on CLI measurement information between the terminal devices.

[0362] The CLI measurement and reporting between terminal devices in the embodiment of the present application can be the aforementioned UE-to-UE CLI.

[0363] Exemplarily, the measurement reporting method provided in the embodiments of the present application may be applied to a L1 / L2 UE-to-UE CLI measurement and reporting mechanism.

[0364] Step S902: The terminal device sends a CSI reporting message to the network device. Correspondingly, the network device receives the CSI reporting message from the terminal device. The CSI reporting message includes measurement results.

[0365] In the measurement reporting method provided in the embodiments of the present application, a terminal device performs CSI measurements on an SBFD time unit. The obtained measurement results take into account the CLI measurement information between terminal devices, thereby implicitly reporting the CLI measurement information to the network device. The network device can obtain CLI measurement information based on CSI reporting messages that include CLI measurement information and CSI reporting messages that only include CSI measurement information.

[0366] In an embodiment of the present application, the CSI reporting message includes SINR and / or CQI. In this solution, the CLI measurement quantity is the same as the CSI measurement quantity, or the CLI reporting quantity is the same as the CSI reporting quantity. The manner in which the terminal device sends the CSI reporting message to the network device in the embodiment shown in Figure 9 can also be referred to as implicit reporting.

[0367] Optionally, the measurement reporting method provided in the embodiment of the present application further includes: performing CSI measurement on a first measurement resource; the first measurement resource includes an SBDF time unit in the time domain. In this solution, the first measurement resource may be a CSI measurement resource.

[0368] Two possible implementations are described below based on the usage of the first measurement resource.

[0369] In one possible implementation, the first measurement resource is a time-frequency resource used for channel measurement or interference measurement. In this solution, the first measurement resource may be, for example, at least one of a CSI-RS resource currently used for channel measurement, a CSI-IM used for interference measurement, or an NZP CSI-RS used for interference measurement.

[0370] In this implementation, since the measurement amount of the CLI is the same as the measurement amount of the CSI, and the measurement resources have not changed, the number of CPUs corresponding to the CSI reporting message is the same as the first value, which is the number of CPUs corresponding to the CSI reporting message that only includes the CSI measurement results. The first value can be defined in the aforementioned CSI measurement and reporting mechanism. CPU .

[0371] In one possible implementation, the first measurement resource is a time-frequency resource dedicated to CLI measurement information between terminal devices. In this solution, the first measurement resource can be, for example, a CLI-RSSI measurement resource dedicated to CLI-RSSI measurement, or an SRS resource dedicated to SRS-RSRP measurement.

[0372] In this implementation, the number of CPUs corresponding to the CSI reporting message is greater than the first value, and the first value is the number of CPUs corresponding to the CSI reporting message that only includes the CSI measurement result. The first value can be defined in the aforementioned CSI measurement and reporting mechanism. CPU In this solution, when generating a CSI reporting message, the terminal device not only needs to measure CSI on the time-frequency resources currently used for channel measurement or interference measurement, but also needs to measure CLI on the first measurement resource. Therefore, the complexity of the UE generating the CSI reporting message increases, that is, the number of CPUs corresponding to the CSI reporting message increases.

[0373] In this embodiment of the present application, if the number of CPUs corresponding to the CSI reporting message is set too large, some CPUs may not be actually occupied, thereby reducing CPU utilization and wasting processing resources. Conversely, if the number of CPUs corresponding to the CSI reporting message is set too small, CLI measurement reporting may not proceed normally. Therefore, it is desirable to set the number of CPUs corresponding to the CSI reporting message close to the number of CPUs actually occupied by the CSI reporting message.

[0374] Optionally, the number of CPUs corresponding to the CSI reporting message satisfies the sum of the first value and the second value, and the second value is greater than 0 and less than or equal to 1.

[0375] Exemplarily, the second value may be 0.5 or 1.

[0376] With respect to the above two possible implementations, the measurement reporting method provided in an embodiment of the present application further includes: the terminal device sending first indication information to the network device. Accordingly, the network device receives the first indication information from the terminal device. The first indication information is used to indicate the number of CPUs corresponding to the CSI reporting message.

[0377] Optionally, before the terminal device performs CSI measurement on the SBFD time unit, the measurement reporting method provided in the embodiment of the present application also includes: the network device sends a first message to the terminal device. Correspondingly, the terminal device receives the first message from the network device. The first message is used to trigger the terminal device to perform CSI measurement on the SBFD time unit; the time interval after the end of the last symbol occupied by the channel carrying the first message to the beginning of the first symbol occupied by the channel carrying the measurement result is the first delay; the time interval after the end of the last symbol in the first measurement resource to the beginning of the first symbol occupied by the channel carrying the measurement result is the second delay; the first delay and the second delay are determined according to the SCS.

[0378] Optionally, the relationship satisfied by the first time delay Z, the second time delay Z' and the parameter μ used to characterize the SCS is as shown in Table 6.

[0379] Table 6

[0380] Alternatively, the relationship satisfied by the first time delay Z, the second time delay Z' and the parameter μ used to characterize the SCS is shown in Table 7.

[0381] Table 7

[0382] In this solution, the value of the first delay can reuse the value of Z1 in Table 1 or Table 2 in the CSI measurement and reporting mechanism; the value of the second delay can reuse the value of Z1′ in Table 1 or Table 2 in the CSI measurement and reporting mechanism.

[0383] The network device sends configuration information to the terminal device. Correspondingly, the terminal device receives the configuration information from the network device. The configuration information is used to configure a first time-frequency resource. The first time-frequency resource is not used for uplink channel / signal transmission. The uplink transmission may be a PUSCH or PUCCH. In one specific embodiment, when the first time-frequency resource overlaps with the time-frequency resource of a PUSCH, the PUSCH performs rate matching on the time-frequency resource within the first time-frequency resource that overlaps with the PUSCH. Rate matching is the process of selecting coded bits from coded bits obtained by channel coding data carried by the PUSCH based on the available time-frequency resources of the PUSCH. This invention solution has the advantage that, since the terminal device does not transmit a PUSCH on the first time-frequency resource, the network device can perform channel or interference measurements on these time-frequency resources, facilitating accurate channel or interference measurements. For example, the network device can measure gNB-to-gNB CLI to perform interference avoidance or suppression, thereby improving network performance.

[0384] In a specific embodiment, the first time-frequency resource includes one or more symbols in the time domain and one or more subcarriers in the frequency domain. In a possible embodiment, the first time-frequency resource is comb-mapped in the frequency domain, where the comb mapping is performed on every other one or more subcarriers, thereby reducing the peak to average power ratio (PAPR) of the terminal device.

[0385] In a specific embodiment, when the PUSCH carries uplink control information (UCI), in one possible embodiment, the first time-frequency resource does not overlap with the symbols carrying the UCI information in the PUSCH, or in other words, the first time-frequency resource does not include the symbols carrying the UCI in the PUSCH. In another possible embodiment, when the first time-frequency resource overlaps with the symbols carrying the UCI in the PUSCH, or in other words, the first time-frequency resource includes the symbols carrying the UCI in the PUSCH, the first time-frequency resource is not used for UCI transmission. For example, the modulation symbols carrying the UCI are not mapped to the first time-frequency resource, or in other words, when determining available resource elements (REs) for UCI transmission, the first time-frequency resource is excluded, or the first time-frequency resource does not belong to the available REs for UCI information. This method has the advantage of reducing the impact of the first time-frequency resource on UCI transmission and ensuring the performance of UCI transmission.

[0386] In a specific embodiment, when the PUSCH is configured with a phase tracking reference signal (PT-RS), a possible embodiment is that the first time-frequency resource does not overlap with the symbol carrying the PT-RS information in the PUSCH, or in other words, the first time-frequency resource does not include the symbol carrying the PT-RS in the PUSCH. In another possible embodiment, the first time-frequency resource overlaps with the symbol carrying the PT-RS in the PUSCH, or in other words, the first time-frequency resource includes the symbol carrying the PT-RS in the PUSCH. When the first time-frequency resource overlaps with the REs occupied by PT-RS, the REs in the first time-frequency resource that overlap with the REs occupied by PT-RS are not effective, or in other words, the first time-frequency resource is not effective for PT-RS, and PT-RS can be transmitted on the first time-frequency resource. The advantage of this method is that it can reduce the impact of the first time-frequency resource on PT-RS transmission and ensure the performance of PT-RS transmission.

[0387] In Figure 2, there are two frequency-discontinuous downlink subbands in the SBFD time slot. The embodiment shown in Figure 12 illustrates the configuration of CSI-RS resources and the method for performing measurement reporting in these two frequency-discontinuous downlink subbands, as well as the CPU usage corresponding to different measurement reporting methods. For example, Figure 12 illustrates a flowchart of another measurement reporting method provided in an embodiment of the present application, comprising the following steps:

[0388] Step S1201: The network device sends first configuration information to the terminal device. Correspondingly, the terminal device receives the first configuration information from the network device.

[0389] Among them, the first configuration information is used by the terminal device to obtain the first CSI-RS resource and the second CSI-RS resource. The first CSI-RS resource is located in the first downlink subband on the SBFD time unit, and the second CSI-RS resource is located in the second downlink subband on the SBFD time unit. The first downlink subband and the second downlink subband are discontinuous in the frequency domain.

[0390] Optionally, the network device configures the first CSI-RS resource and the second CSI-RS resource in the following three ways:

[0391] 1) Mode 1: The first configuration information is used to configure two associated CSI-RS resources, one of the two associated CSI-RS resources is a first CSI-RS resource, and the other CSI-RS resource is a second CSI-RS resource.

[0392] In other words, the network device can configure a CSI-RS resource in each of two discontinuous downlink subbands in the frequency domain. That is, the network device can configure a first CSI-RS resource in the first downlink subband and a second CSI-RS resource in the second downlink subband. These two CSI-RS resources are associated.

[0393] In Method 1, the configuration method of the first CSI-RS resource or the second CSI-RS resource can refer to the existing CSI-RS resource configuration method. For example, the network device configures two CSI-RS resources, each of which is independently configured with a frequency starting position and bandwidth. These two CSI-RS resources are the first CSI-RS resource and the second CSI-RS resource.

[0394] 2) Mode 2: The first configuration information is used to configure one CSI-RS resource, where the one CSI-RS resource includes a first CSI-RS resource and a second CSI-RS resource.

[0395] For example, a network device configures a CSI-RS resource, and the CSI-RS resource is configured with two frequency domain resources. Specifically, the CSI-RS resource is configured with two frequency starting positions. Optionally, the CSI-RS resource can also be configured with two bandwidths, each associated with the two frequency starting positions. The two frequency starting positions and corresponding bandwidths of the CSI-RS resource can be used to determine two CSI-RS resources, namely the first CSI-RS resource and the second CSI-RS resource.

[0396] 3) Mode 3: The first configuration information is used to configure a CSI-RS resource.

[0397] After receiving the first configuration information, the terminal device can determine the CSI-RS resource located in the first downlink subband in the one CSI-RS resource as the first CSI-RS resource, and determine the CSI-RS resource located in the second downlink subband in the one CSI-RS resource as the second CSI-RS resource.

[0398] Step S1202: The terminal device sends a CSI measurement report to the network device according to the first configuration information. Correspondingly, the network device receives the CSI measurement report from the terminal device.

[0399] In a possible implementation, when the number of CSI measurement reports in step S1202 is one and the one CSI measurement report includes a measurement result corresponding to the first CSI-RS resource and a measurement result corresponding to the second CSI-RS resource, the number of CPUs corresponding to the one CSI measurement report is greater than a first value, where the first value is the number of CPUs corresponding to the one CSI measurement report that only includes the measurement result corresponding to the first CSI-RS resource, or the first value is the number of CPUs corresponding to the one CSI measurement report that only includes the measurement result corresponding to the second CSI-RS resource.

[0400] In this embodiment of the present application, the number of CPUs corresponding to a CSI measurement report that includes only the measurement result corresponding to the first CSI-RS resource may be the same as or different from the number of CPUs corresponding to a CSI measurement report that includes only the measurement result corresponding to the second CSI-RS resource. For example, when a CSI measurement report that includes the measurement result corresponding to the first CSI-RS resource and a CSI measurement report that includes only the measurement result corresponding to the second CSI-RS resource have the same configuration, for example, when the measurement amount is the same, the number of CPUs corresponding to the two may be the same.

[0401] In the embodiment of the present application, the measurement result corresponding to the first CSI-RS resource (or the second CSI-RS resource) may be a measurement result obtained by the terminal device performing CSI measurement on the first CSI-RS resource (or the second CSI-RS resource). The determination of the first value may refer to the aforementioned CSI measurement and reporting mechanism. CPU For details on the determination of the above, please refer to the relevant description in Title 4.

[0402] Exemplarily, the number of CPUs corresponding to one CSI measurement report is twice the first value.

[0403] In another possible implementation, in step S1202, the number of CSI measurement reports is one, and the one CSI measurement report includes measurement results corresponding to the first CSI-RS resource and the second CSI-RS resource, or in the case where the number of CSI measurement reports is two, and the first of the two CSI measurement reports includes only the measurement results corresponding to the first CSI-RS resource, and the second of the two CSI measurement reports includes only the measurement results corresponding to the second CSI-RS resource, the number of CPUs corresponding to one CSI measurement report is a first value. The first value is the number of CPUs corresponding to one CSI measurement report that includes only the measurement results corresponding to the first CSI-RS resource, or the first value is the number of CPUs corresponding to one CSI measurement report that includes only the measurement results corresponding to the second CSI-RS resource. In other words, in the above two cases, the number of CPUs corresponding to one CSI measurement report can be 0 defined in the aforementioned CSI measurement and reporting mechanism. CPU .

[0404] The measurement results corresponding to the first CSI-RS resource and the second CSI-RS resource may be measurement results obtained by the terminal device performing CSI measurement on the first CSI-RS resource and the second CSI-RS resource.

[0405] When CSI measurement reporting is associated with periodic or semi-continuous CSI-RS resources, a portion of the CSI-RS transmission opportunities corresponding to the CSI-RS resources may be located on SBFD symbols in some time slots, and another portion of the CSI-RS transmission opportunities may be located on non-SBFD symbols in other time slots. The embodiment shown in Figure 13 illustrates different ways of configuring CSI measurement reporting and its associated CSI-RS resources, as well as the CPU usage corresponding to different configurations. For example, Figure 13 shows a flowchart of another measurement reporting method provided in an embodiment of the present application, comprising the following steps:

[0406] Step S1301: The network device sends first configuration information to the terminal device. Correspondingly, the terminal device receives the first configuration information from the network device.

[0407] The first configuration information is used to configure one or two CSI measurement reports and one or two CSI-RS resources associated with the CSI measurement reports.

[0408] Optionally, the first configuration information has the following four possible implementations:

[0409] 4) Mode 4: The first configuration information is used to configure a CSI measurement report and a CSI-RS resource associated with the CSI measurement report.

[0410] The CSI-RS transmission opportunity corresponding to the one CSI-RS resource is located on SBFD symbols or non-SBFD symbols in different time slots.

[0411] 5) Mode 5: The first configuration information is used to configure one CSI measurement report and two CSI-RS resources associated with the one CSI measurement report.

[0412] Among them, the CSI-RS transmission opportunity corresponding to the first CSI-RS resource of the two CSI-RS resources is located on the SBFD symbols of different time slots; the CSI-RS transmission opportunity corresponding to the second CSI-RS resource of the two CSI-RS resources is located on the non-SBFD symbols of different time slots; and the one CSI measurement report includes the measurement result corresponding to the first CSI-RS resource and the measurement result corresponding to the second CSI-RS resource.

[0413] In mode 5, the terminal device may perform CSI measurement on the first CSI-RS resource and the second CSI-RS resource respectively to obtain a measurement result corresponding to the first CSI-RS resource and a measurement result corresponding to the second CSI-RS resource.

[0414] Optionally, when the measurement result corresponding to the first CSI-RS resource and the measurement result corresponding to the second CSI-RS resource are reported at the same reporting time of the CSI measurement report, the number of CPUs corresponding to the one CSI measurement report is greater than a first value, and the first value is the number of CPUs corresponding to a CSI measurement report that only includes the measurement result corresponding to the first CSI-RS resource, or the first value is the number of CPUs corresponding to a CSI measurement report that only includes the measurement result corresponding to the second CSI-RS resource.

[0415] The determination of the first value may refer to the aforementioned CSI measurement and reporting mechanism. CPU For details on the determination, see the relevant description in heading 4. Exemplarily, the number of CPUs corresponding to the one CSI measurement report is twice the first value.

[0416] 6) Mode 6: The first configuration information is used to configure two CSI measurement reports and one CSI-RS resource associated with the two CSI measurement reports.

[0417] Among them, the first CSI measurement report of the two CSI measurement reports only includes the measurement results obtained in the CSI-RS transmission opportunity corresponding to the SBFD symbol of the one CSI-RS resource; the second CSI measurement report of the two CSI measurement reports only includes the measurement results obtained in the CSI-RS transmission opportunity corresponding to the non-SBFD symbol of the one CSI-RS resource.

[0418] In mode 6, the terminal device may perform CSI measurement during the CSI-RS transmission timing corresponding to the SBFD symbol of the one CSI-RS resource, and include the obtained measurement result in the first CSI measurement report. The terminal device may also perform CSI measurement during the CSI-RS transmission timing corresponding to the non-SBFD symbol of the one CSI-RS resource, and include the obtained measurement result in the second CSI measurement report.

[0419] 7) Mode 7: The first configuration information is used to configure two CSI measurement reports and two CSI-RS resources.

[0420] Among them, the first CSI measurement report of the two CSI measurement reports is associated with the first CSI-RS resource of the two CSI-RS resources, and the second CSI measurement report of the two CSI measurement reports is associated with the second CSI-RS resource of the two CSI-RS resources; the CSI-RS transmission opportunity corresponding to the first CSI-RS resource is located on the SBFD symbols of different time slots; and the CSI-RS transmission opportunity corresponding to the second CSI-RS resource is located on the non-SBFD symbols of different time slots.

[0421] In the above method 4, method 6 or method 7, the number of CPUs corresponding to one CSI measurement report can be defined in the aforementioned CSI measurement and reporting mechanism. CPU .

[0422] Step S1302: The terminal device sends one or two CSI measurement reports to the network device. Correspondingly, the network device receives one or two CSI measurement reports from the terminal device.

[0423] It can be understood that the embodiment shown in FIG12 describes the configuration related to CSI measurement, different measurement reporting methods and their corresponding CPU occupancy from the perspective of the frequency domain, and the embodiment shown in FIG13 describes the configuration related to CSI measurement, different measurement reporting methods and their corresponding CPU occupancy from the perspective of the time domain. The embodiments shown in FIG12 and FIG13 can also be implemented in combination. Among them, clarifying the CPU occupancy corresponding to different measurement reporting methods can enable the terminal device to correctly process the CSI measurement reports under different measurement reporting methods, and can ensure that the network device and the terminal device have a consistent understanding of the amount of CPU occupied by a CSI measurement report under different measurement reporting methods, thereby avoiding communication errors.

[0424] It can be understood that in the above embodiments, the methods and / or steps implemented by the terminal device can also be implemented by components that can be used for the terminal device (such as chips or circuits) or devices including terminal devices; the methods and / or steps implemented by the network device can also be implemented by components that can be used for the network device (such as chips or circuits) or devices including network devices.

Whether a function is executed in the form of hardware or computer software driving hardware depends on the specific application and design constraints of the technical solution.

[0426] In the embodiment of the present application, the terminal device or network device can be divided into functional modules according to the above method embodiment. For example, each functional module can be divided according to each function, or two or more functions can be integrated into one processing module. The above integrated modules can be implemented in the form of hardware or in the form of software functional modules.
