Description

Communication method and device, terminal equipment and network equipment

[0001] This invention claims priority from the prior application No. 202311609641.2 filed on November 29, 2023, entitled “Communication Method and Apparatus, Terminal Equipment and Network Equipment”. The contents of the aforementioned prior application are incorporated into this text by way of introduction. Technical Field

[0002] The present application relates to the field of communication technology, and in particular to a communication method and apparatus, terminal equipment, and network equipment. Background Art

[0003] In a time division duplexing (TDD) system, all frequency resources on a TDD carrier must transmit in the same direction at the same time, either uplink or downlink. Consequently, TDD systems have the following resource types: different frequency resources on the same TDD carrier use the same uplink and downlink time slot ratio. However, this resource type suffers from the problem of inflexible configuration of the uplink and downlink time slot ratio.

[0004] With the development and popularization of information and communication technologies, business needs are becoming more diverse and personalized. Different vertical industries have different application scenarios and service requirements. For example, home, office, and industrial scenarios have different requirements for network bandwidth, transmission rate, and latency. In this context, to better meet the transmission needs of various services and different terminal devices, communication systems may simultaneously utilize multiple resource types, such as low-latency resources, high-reliability resources, and high-speed resources, to support different uplink and downlink transmission requirements.

[0005] However, when the measurement resources configured for channel state information (CSI) measurement / CSI reporting belong to multiple resource types at the same time, the channel measurement results or interference measurement results measured by the measurement resources may not be able to reflect a certain resource type alone, resulting in the network being unable to accurately perform channel assessment or interference assessment on a certain resource type alone. Summary of the Invention

[0006] The present application provides a communication method and apparatus, a terminal device, and a network device, in the hope of solving the problem that the channel measurement results or interference measurement results measured by the measurement resources may not reflect a certain resource type alone, resulting in the network being unable to accurately perform channel evaluation or interference evaluation on a certain resource type alone.

In this way, after the network device obtains the channel measurement result or the interference measurement result, the network device can perform accurate channel evaluation or interference evaluation on a resource type separately, so as to adapt to the scenario where the network expects to perform channel evaluation or interference evaluation on only one resource type.

[0025] Optionally, the chip module further includes a transceiver component, and the processor executes the sending step and / or receiving step in the method designed in the first aspect or the second aspect through the transceiver component.

[0088] For another example, the communication system 10 may include other terminal devices in addition to the terminal device 120.

[0089] 2. A communication method

[0090] 1. Description

[0091] In order to better meet the transmission requirements of various services and different terminal devices, resources of multiple resource types may exist simultaneously in a communication system.

[0092] For example, in a time division duplexing (TDD) system, all frequency domain resources of a TDD carrier must have the same transmission direction at the same time, that is, both uplink or downlink. In other words, the TDD system has the following resource types: different frequency domain resources on the same TDD carrier use the same uplink and downlink time slot ratio. However, this type of resource type cannot meet the differentiated needs of different services for uplink and downlink transmission because the uplink and downlink time slot ratio cannot be flexibly configured. To this end, the communication system introduces the following resource type: different frequency domain resources on the same TDD carrier use different uplink and downlink time slot ratios, so that this type of resource type can flexibly configure the uplink and downlink time slot ratio. Therefore, in order to meet the transmission requirements of various services and different terminal devices, the communication system may configure the above two resource types to the terminal device.

[0093] During CSI measurement / CSI reporting, the network may configure measurement resources for multiple resource types. For example, different frequency domain resources on the same TDD carrier may use the same uplink and downlink time slot ratio, while different frequency domain resources on the same TDD carrier may use different uplink and downlink time slot ratios. In this case, the channel or interference measurement results obtained from the measurement resources may not reflect a specific resource type, making it impossible for the network to perform accurate channel or interference assessment for a specific resource type.

[0094] Based on this, this embodiment considers that the measurement resources configured for CSI measurement belong to one of multiple resource types. Because the measurement resources configured for CSI measurement include measurement resources associated with CSI reporting, the measurement resources associated with CSI reporting also belong to the same resource type. Alternatively, this embodiment considers that the measurement resources configured for CSI measurement belong to multiple resource types, but the measurement resources associated with CSI reporting belong to one of the multiple resource types.

[0095] Because the channel measurement result or interference measurement result reported by the CSI is obtained by performing channel measurement or interference measurement based on the measurement resource associated with the CSI report, when the measurement resource associated with the CSI report belongs to a single resource type, the channel measurement result or interference measurement result reported by the CSI report can independently reflect the single resource type. In this way, after the network device obtains the channel measurement result or interference measurement result, it can independently perform accurate channel assessment or interference assessment for the single resource type, thereby adapting to scenarios where the network desires to perform channel assessment or interference assessment for only the single resource type.

[0096] It should be noted that the "multiple resource types" described in this embodiment may include different frequency domain resources on the same TDD carrier using the same uplink and downlink time slot ratio, different frequency domain resources on the same TDD carrier using different uplink and downlink time slot ratios, subband full duplex (SBFD), non-subband full duplex (non-SBFD), non-overlapping full duplex, overlapping full duplex, etc. SBFD means that different subbands on the same carrier use different uplink and downlink time slot ratios; non-SBFD means that different subbands on the same carrier use the same uplink and downlink time slot ratio; non-overlapping full duplex means that uplink and downlink are allowed to be performed simultaneously on non-overlapping subbands within the same carrier; overlapping full duplex means that uplink and downlink are allowed to be performed simultaneously on overlapping / same subbands within the same carrier.

[0097] For example, in Figure 2, simultaneous uplink and downlink are allowed on non-overlapping subbands within the same carrier; in (a) of Figure 2, different subbands of the same carrier use the same uplink and downlink time slot ratio, and in (b), (c) and (d) of Figure 2, different subbands of the same carrier use different uplink and downlink time slot ratios.

[0098] 2. SBFD

[0099]

symbol

[0100]

SBFD

[0101] To avoid the limitation of uplink and downlink time slot ratio in TDD system as much as possible and taking into account the implementation complexity of network equipment, this embodiment considers SBFD to support uplink and downlink transmission at the same time, thereby improving spectrum utilization and flexibility.

[0102] Optionally, the network configures SBFD resources through network signaling (such as DCI, MAC signaling, MAC CE, system information, dedicated information, UE-specific signaling, etc.) The SBFD resources may include time-domain SBFD resources and frequency-domain SBFD resources.

[0103] Time-domain SBFD resources can be understood as SBFD resources in the time domain, which may include SBFD symbols, SBFD time slots, SBFD mini-time slots, SBFD subframes, etc.

[0104] Frequency-domain SBFD resources can be understood as SBFD resources in the frequency domain, which can include SBFD uplink subbands and SBFD downlink subbands. Among them, the SBFD uplink subband can be used for uplink transmission or uplink reception, and the SBFD downlink subband can be used for downlink transmission.

[0105] SBFD Symbol

[0106] SBFD symbols are defined as symbols that have been configured to allow SBFD operations or symbols that have been configured for SBFD operations. In other words, the original symbol's uplink or downlink transmission attributes are changed due to the configuration of SBFD operations.

[0107] Of course, the SBFD uplink subband can be referred to as an "uplink subband," and the SBFD downlink subband can be referred to as a "downlink subband." Furthermore, the present application may replace "SBFD symbol" with "SBFD time slot," "SBFD mini-time slot," "SBFD subframe," etc. Their respective meanings are similar to those of "SBFD symbol," and are not specifically limited thereto.

[0108] Optionally, a guard band is provided between the uplink sub-band and the downlink sub-band, so that interference between the uplink and downlink can be avoided as much as possible through the guard band.

[0109] Optionally, the SBFD symbols include SBFD downlink symbols, SBFD uplink symbols, and SBFD flexible symbols.

[0110] SBFD downlink symbols are downlink symbols that are configured to allow SBFD operation, or are downlink symbols that are configured for SBFD operation. Therefore, SBFD downlink symbols can support both downlink and uplink transmissions.

[0111] For example, the network may configure a portion of uplink subbands in the frequency band of downlink symbols in the original time slot through network signaling, so that the downlink symbols can support uplink and downlink transmissions, thereby configuring the SBFD operation.

[0112] SBFD uplink symbols are uplink symbols that are configured to allow SBFD operation, or are uplink symbols that are configured for SBFD operation. Therefore, SBFD uplink symbols can support both uplink and downlink transmission.

[0113] For example, the network may configure a portion of downlink subbands in the frequency band of the uplink symbols in the original time slot through network signaling, so that the uplink symbols can support uplink transmission and downlink transmission, thereby configuring the SBFD operation.

[0114] SBFD flexible symbols are flexible symbols that are configured to allow SBFD operation, or are flexible symbols that are configured for SBFD operation. Therefore, SBFD flexible symbols can be configured by the network to support both uplink and downlink transmission, that is, to support both uplink and downlink transmission.

[0115] For example, the network may configure a portion of uplink subbands and a portion of downlink subbands in the frequency band of the flexible symbol in the original time slot through network signaling, so that the flexible symbol can support uplink transmission and downlink transmission, thereby configuring the SBFD operation.

[0116]

non-SBFD symbols

[0117] In order to distinguish from "SBFD symbols", non-SBFD symbols can be understood as symbols that are not configured for SBFD operation, or original symbols in the time slot, or symbols that do not allow SBFD operation.

[0118] In other words, the original symbol's attribute of supporting uplink or downlink transmission remains unchanged because SBFD is not configured. That is, the original downlink symbol can only support downlink transmission; the original uplink symbol can only support downlink transmission; the original flexible symbol can be configured by the network to support uplink or downlink transmission, that is, it can only support one transmission mode.

[0119] It should be noted that, in order to distinguish from the SBFD symbols mentioned above, this application introduces "non-SBFD downlink symbols", "non-SBFD uplink symbols" and "non-SBFD flexible symbols".

[0120] Optionally, non-SBFD symbols, including non-SBFD downlink symbols, non-SBFD uplink symbols, and non-SBFD flexible symbols, may include original downlink symbols, original uplink symbols, and original flexible symbols.

[0121] Non-SBFD downlink symbols are downlink symbols that are not configured for SBFD operation, or are downlink symbols for which SBFD operation is not configured. In other words, non-SBFD downlink symbols are genuine downlink symbols. Therefore, non-SBFD downlink symbols support only downlink transmission.

[0122] Non-SBFD uplink symbols are uplink symbols that are not configured for SBFD operation, or are uplink symbols for which SBFD operation is not configured. In other words, non-SBFD uplink symbols are original uplink symbol numbers. Therefore, non-SBFD uplink symbols support only uplink transmission.

[0123] Non-SBFD flexible symbols are flexible symbols that are not configured for SBFD operation, or flexible symbols that are not configured for SBFD operation. In other words, non-SBFD flexible symbols are essentially flexible symbols. Therefore, non-SBFD flexible symbols can be configured by the network to support either uplink or downlink transmission, meaning they only support one transmission mode.

[0124] 3. CSI-related configuration

[0125] Measurement Resources

[0126] CSI-related configurations may include CSI reporting configurations and / or CSI resource configurations, which may be defined by the higher-level parameter CSI-MeasConfig (CSI measurement configuration). CSI-MeasConfig may indicate (include / configure / carry) the following two higher-level parameters: CSI-ResourceConfig (CSI resource configuration) and CSI-ReportConfig (CSI reporting configuration).

[0127] In addition, since CSI-ReportConfig may indicate / include CSI-ResourceConfigId (CSI resource configuration identifier), CSI-ResourceConfig may be associated (corresponding / mapped) to CSI-ReportConfig through CSI-ResourceConfigId.

[0128] CSI-ReportConfig can be used to configure CSI reporting, that is, to configure CSI reporting.

[0129] CSI-ResourceConfig can be used to configure CSI measurement resources, such as CSI-RS. In addition, CSI-ResourceConfig can configure CSI-Resource-Set (CSI resource set), which can contain the most basic CSI-RS resources (such as CSI-RS-Resource).

[0130] CSI-Resource-Set can indicate / include at least one of the following: NZP-CSI-RS-ResourceSet (NZP (Non-Zero-Power)-CSI-RS resource set), CSI-IM-ResourceSet (CSI-IM (CSI Interference Measurement) resource set), and CSI-SSB-ResourceSet (synchronization signal block SSB resource set).

[0131] NZP-CSI-RS-ResourceSet can be used for channel measurement and / or interference measurement; CSI-IM-ResourceSet can be used for interference measurement; and CSI-SSB-ResourceSet can be used for channel measurement.

[0132] CSI-ResourceConfig and / or NZP-CSI-RS-ResourceSet can configure one or more NZP CSI-RS resource sets. Each NZP CSI-RS resource set may include K (K≥1) NZP CSI-RS resources.

[0133] For example, the network device sends a CSI resource configuration (CSI resource setting) to the terminal device via an RRC message. Each CSI resource setting includes S (S ≥ 1, and S is an integer) CSI resource sets, and each CSI resource set includes K (K ≥ 1, and K is an integer) NZP-CSI-RS resources. The terminal device can receive CSI-RS on the K NZP-CSI-RS resources indicated by the network device.

[0134] In summary, a measurement resource can be a CSI resource setting, a CSI resource set, or a CSI resource. A CSI resource setting can include at least one CSI resource set, a CSI resource set can include at least one CSI resource, and a CSI resource can include at least one of a CSI-RS resource, a CSI-IM resource, and an SSB resource. A CSI-RS resource can be used for channel measurement and / or interference measurement; a CSI-IM resource can be used for interference measurement; and an SSB resource can be used for channel measurement.

[0135] In addition, measurement resources can be divided into channel measurement resources (CMR) and interference measurement resources (IMR). Channel measurement resources refer to measurement resources used for channel measurement, and interference measurement resources refer to measurement resources used for interference measurement.

[0136] Time domain behavior

[0137] Time domain behaviors may include periodic, semi-persistent, and aperiodic. The following uses CSI-RS as an example for illustration.

[0138] The time domain behavior of CSI-RS includes periodic CSI-RS, aperiodic CSI-RS, and non-semi-persistent CSI-RS, and the time domain behavior of CSI-RS can be indicated by a high-level parameter (such as resource type resourceType).

[0139] For periodic CSI-RS, after the network device configures information of the periodic CSI-RS and the configuration takes effect, the network device will periodically send the CSI-RS to the terminal device.

[0140] For aperiodic CSI-RS, after the network device configures the information of the aperiodic CSI-RS, the network device does not send the CSI-RS immediately, but first sends a signaling notification to the terminal device, and then sends the aperiodic CSI-RS to the terminal device.

[0141] For non-semi-persistent CSI-RS, after the network device configures the semi-persistent CSI-RS information, the network device will not send CSI-RS immediately. Instead, it will first send signaling to notify the terminal device. Then, after the activation signaling takes effect, the network device will send semi-persistent CSI-RS to the terminal device. Once the network device triggers the transmission of semi-persistent CSI-RS, it will periodically send CSI-RS unless the network device sends deactivation signaling.

[0142] The time domain behavior of CSI reporting includes periodic CSI reporting, aperiodic CSI reporting, semi-persistent CSI reporting carried on the physical uplink control channel (PUCCH), and semi-persistent CSI reporting carried on the physical uplink shared channel (PUSCH). The time domain behavior of CSI reporting can be indicated by a high-level parameter (such as the report configuration type (reportConfigType)).

[0143] For non-periodic CSI reporting and semi-persistent CSI reporting carried on PUSCH, the network device will also configure the high-level parameters TriggerState and reportTriggerSize to cooperate with the CSI request field (CSI request field) in DCI (downlink control information, DCI).

[0144] For periodic CSI reporting, once the periodic CSI-RS Resource and Report parameters are configured through RRC messages (or RRC signaling), they will take effect immediately without the need to activate / trigger CSI-RS transmission and CSI reporting through MAC-CE / DCI.

[0145] For semi-persistent CSI reporting carried on PUCCH, if semi-persistent CSI-RS transmission is configured through RRC messaging, it is necessary to first activate CSI-RS transmission through MAC CE1 and then activate CSI reporting through MAC CE2. If periodic CSI-RS transmission is configured through RRC messaging, it is not necessary to activate CSI-RS transmission through MAC CE1, and only CSI reporting needs to be activated through MAC CE2.

[0146] For semi-persistent CSI reporting carried on PUSCH, if semi-persistent CSI-RS transmission is configured through RRC messaging, it is necessary to first activate CSI-RS transmission through MAC CE1, and then trigger CSI reporting through DCI. If periodic CSI-RS transmission is configured through RRC messaging, it is not necessary to activate CSI-RS transmission through MAC CE1, and only CSI reporting needs to be triggered through DCI.

[0147] It should be noted that for DCI, the DCI can be DCI format (format) 0_1 scrambled using SP-CSI-RNTI (semi-persistent CSI RNTI), and the CSI request field in the DCI can be associated with the corresponding trigger state (TriggerState) by setting the codepoint. The associated CSI-ReportConfig will be defined in the TriggerState, so that the CSI-ReportConfig associated with the PUSCH upper semi-persistent CSI report can be found through the TriggerState.

[0148] For aperiodic CSI reporting, aperiodic CSI reporting is triggered by DCI, and the process is similar to the semi-persistent CSI reporting described above. When the codepoint of the CSI request field in DCI format 0_1 / 0_2 is used to associate the corresponding TriggerState, unlike the DCI trigger in the semi-persistent CSI reporting described above, if the CSI request field value is 0, it indicates that semi-periodic CSI reporting is not required; if the CSI request field value is 1, it indicates that the aperiodic CSI reporting associated with TriggerState 1 is triggered, and so on.

[0149] CSI reporting band

[0150] The reporting frequency configuration information (reportFreqConfiguration) in CSI-ReportConfig is used to indicate the frequency granularity of CSI reporting.

[0151] The CSI reporting setting configuration can define the CSI reporting band as a subset of subbands in a bandwidth part (BWP). In other words, the active BWP can be divided into multiple subbands, and a subset (i.e., part of the subbands) of the multiple subbands can be defined as the CSI reporting band.

[0152] Optionally, reportFreqConfiguration may indicate that csi-ReportingBand is a contiguous or non-contiguous subset of the subbands in the BWP for which CSI should be reported.

[0153] Optionally, reportFreqConfiguration can indicate that wideband CQI reporting or subband CQI reporting can be configured by higher-layer parameters (such as CQI format indicator cqi-FormatIndicator). When wideband CQI reporting is configured, one wideband CQI is reported for each codeword in the entire CSI reporting band. When subband CQI reporting is configured, one CQI is reported for each codeword in each subband in the CSI reporting band.

[0154] Optionally, reportFreqConfiguration may indicate that wideband PMI reporting or subband PMI reporting may be configured by higher-layer parameters (e.g., PMI format indication pmi-FormatIndicator). When wideband PMI reporting is configured, one wideband PMI is reported for the entire CSI reporting band. When subband PMI reporting is configured, a single wideband indication is reported for the entire CSI reporting band, except for 2 antenna ports, and one subband indication is reported for each subband in the CSI reporting band. When subband PMI is configured with 2 antenna ports, one PMI is reported for each subband in the CSI reporting band.

[0155] CSI reference resource

[0156] It should be noted that CSI reporting corresponds to a CSI reference resource. When the network device configures at least one measurement resource for CSI measurement to the terminal device, the at least one measurement resource may include a CSI reference resource corresponding to the CSI reporting and a measurement resource associated with the CSI reporting.

[0157] For example, for periodic CSI reporting, CSI is reported periodically, and each CSI report corresponds to a CSI reference resource.

[0158] The CSI reference resource can be a block of time-frequency resources. The time domain of the CSI reference resource can be a time slot, and the frequency domain of the CSI reference resource can be the frequency granularity of the CSI measurement. For example, when the CSI is measured in subband, the frequency domain of the CSI reference resource is subband; when the CSI is measured in wideband, the frequency domain of the CSI reference resource is wideband.

[0159] When the uplink time slot where the CSI is reported is time slot n' (n' represents the time slot index), the downlink time slot where the CSI reference resource is located is time slot Indicates the parameters of high-level configuration, Indicates that in frequency range 1 and K offset =0, μ DL Indicates the downlink subcarrier spacing configuration.

[0160] Since the CSI reference resource is a downlink resource, the time domain of the CSI reference resource is the downlink time slot. In this way, time slot n represents the downlink time slot corresponding to time slot n′ and is calculated as follows:

[0161] Among them, μ UL Indicates the uplink subcarrier spacing configuration, and μ offset,DL Indicates the downlink time slot offset, and Indicates the uplink timeslot offset.

[0162] n CSI_ref Indicates the time slot offset between time slot n and the CSI reference resource located in the valid downlink time slot.

[0163] For periodic or non-continuous CSI reporting, if the CSI reporting is associated with a channel measurement resource (such as a CSI-RS / SSB for channel measurement), then n CSI_ref is greater than or equal to The CSI reference resource corresponding to the CSI report is located at the minimum value of the valid downlink time slot.

[0164] For example, assuming that the uplink and downlink subcarrier spacing configurations are the same, that is, μ DL =μ UL = 0. From greater than or equal to Starting from the minimum value in CSI_ref for Calculated And determine whether time slot n-4 is a valid downlink time slot. If time slot n-4 is a valid downlink time slot, the CSI reference resource is located in time slot n-4; if time slot n-4 is not a valid downlink time slot, then set n CSI_ref for Calculated It then determines whether time slot n-5 is a valid downlink time slot. If so, the CSI reference resource is located in time slot n-5. If not, the search continues until a valid downlink time slot is found.

[0165] For periodic or non-continuous CSI reporting, if the CSI reporting is associated with multiple channel measurement resources (such as multiple CSI-RS / SSBs for channel measurement), then n CSI_ref is greater than or equal to The CSI reference resource corresponding to the CSI report is located at the minimum value of the valid downlink time slot.

[0166] For aperiodicity, if the DCI used to trigger the CSI reporting is in the same time slot as the CSI reporting, the CSI reference resource is in the time slot where the DCI is located; otherwise, n CSI_ref is greater than or equal to The minimum value of the CSI reference resource corresponding to the CSI report is located in the valid downlink time slot, It represents the number of symbols contained in a time slot, and Z′ represents the processing time of CSI calculation.

[0167] It should be noted that whether a downlink time slot is a "valid downlink time slot" needs to meet the following conditions: the downlink time slot includes at least one downlink symbol or flexible symbol configured by high-layer signaling; and / or the downlink time slot is not within the configured measurement gap.

[0168] The CSI reference resource can have the following two functions.

[0169] Function 1: Used to calculate channel quality indicator (CQI)

[0170] Channel measurement is inherently dependent on the implementation of the terminal device. For example, some terminal devices are very capable and can achieve the target block error rate (BLER) requirement using a certain modulation and coding scheme (MCS) at an SINR of 10dB. However, some terminal devices are less capable and require an SINR of 12dB to achieve the target BLER (the target BLER is configured by the network equipment). Therefore, if two terminal devices both measure an SINR of 10dB, the CQI values ​​they report back should be different.

[0171] Furthermore, even for the same terminal device, different packet sizes (TBS) can result in different BLERs. For example, if SINR = 10dB, and the current TBS is 1000 bits, using a specific MCS, the BLER is 0.01. However, if the TBS is 500 bits and the same MCS is used, the corresponding BLER might be 0.1. These two differences are significant.

[0172] Therefore, when quantizing the CQI, a concept such as CSI reference resources is needed so that the network device can know under what circumstances the CQI of the terminal device is calculated through the CSI reference resources.

[0173] Assume that a terminal device uses CSI-RS for channel measurement to obtain channel conditions, such as SINR. The terminal device then assumes that a downlink data packet is transmitted on the CSI reference resource, and the corresponding channel conditions are those measured by the CSI-RS. At this point, the terminal device selects a CQI from the CQI table that ensures that the BLER of the hypothetical downlink data packet transmitted under the measured channel conditions is less than the target BLER.

[0174] Function 2: Used to determine the measurement resources associated with CSI reporting

[0175] The network device may configure at least one measurement resource for CSI measurement to the terminal device. The at least one measurement resource may include a CSI reference resource corresponding to the CSI report and a measurement resource associated with the CSI report. The time domain location of the measurement resource associated with the CSI report may be located before the CSI reference resource corresponding to the CSI report. In other words, the measurement resource located before the CSI reference resource corresponding to the CSI report may serve as the measurement resource associated with the CSI report. As for which measurements can serve as the measurement resource associated with the CSI report, this may be determined by higher-layer signaling configuration, protocol provisions, pre-configuration, or autonomously by the terminal device.

[0176] For example, taking periodic measurement resources as an example, as shown in Figure 3, the periodic measurement resources include measurement resources associated with CSI reporting, and the time domain location of the measurement resources associated with CSI reporting is located before the CSI reference resource corresponding to the CSI reporting. In other words, only the measurement resources before the CSI reference resource corresponding to the CSI reporting can be used as the measurement resources associated with the CSI reporting. As for which resource measurements can be used as the measurement resources associated with the CSI reporting, the network can further configure them through higher-layer signaling. For example, the network can configure the resource measurement 310 closest to / adjacent to the CSI reference resource as the measurement resource associated with the CSI reporting.

[0177] 4. CSI measurement / CSI reporting

[0178] During the CSI measurement / CSI reporting process, to ensure that the channel measurement results or interference measurement results obtained from the measured resources can uniquely reflect a specific resource type, so that the network can accurately perform channel or interference assessment for that specific resource type, this embodiment is described below using multiple solutions. The solutions may be independent of each other or combined and associated with each other, and the same content in different solutions may be referenced across them without further elaboration.

[0179] [Scheme 1]

[0180] In "Scheme 1", this embodiment considers that the measurement resources configured for CSI measurement belong to one resource type among multiple resource types. Because the measurement resources configured for CSI measurement include measurement resources associated with CSI reporting, the measurement resources associated with CSI reporting also belong to the same resource type.

[0181] In this way, since the channel measurement result or interference measurement result reported by the CSI is obtained by performing channel measurement or interference measurement based on the measurement resources associated with the CSI report, when the measurement resources configured for the CSI measurement belong to the same resource type, the channel measurement result or interference measurement result reported by the CSI can independently reflect the same resource type.

[0182] Optionally, a resource type to which the measurement resource configured for CSI measurement belongs is configured by the network.

[0183] For example, in the case of interaction between a network device and a terminal device, the network device sends first information, where the first information is used to indicate a resource type, from among multiple resource types, to which the measurement resources configured for CSI measurement belong. Correspondingly, the terminal device receives the first information. The first information may be carried by higher-layer signaling (e.g., RRC signaling, MAC signaling) / DCI, etc.

[0184] In the following, this embodiment is described by taking as an example that the multiple resource types include a first resource type and a second resource type, and the measurement resources configured for CSI measurement belong to the first resource type or the second resource type.

[0185] The first resource type is one of the multiple resource types. For example, the first resource type may be SBFD, non-overlapping full-duplex, or different frequency domain resources on the same TDD carrier using different uplink and downlink time slot ratios.

[0186] The second resource type is one of the multiple resource types, and the second resource type is different from the first resource type. For example, the second resource type can be non-SBFD, overlapping full-duplex, or different frequency domain resources on the same TDD carrier using the same uplink and downlink time slot ratio.

[0187] For the measurement resources configured for CSI measurement, taking the interaction between a network device and a terminal device as an example, the network device sends information for configuring at least one measurement resource for CSI measurement; correspondingly, the terminal device receives the information and obtains the at least one measurement resource based on the information. The network device sends first information, and the first information is used to indicate a resource type to which the at least one measurement resource belongs from a plurality of resource types; correspondingly, the terminal device receives the first information. The at least one measurement resource belongs to the first resource type or the second resource type, ensuring that the at least one measurement resource belongs to the same resource type. At the same time, since the at least one measurement resource belongs to the same resource type, and the at least one measurement resource includes the measurement resource associated with the CSI report, the measurement resource associated with the CSI report also belongs to the same resource type.

[0188] Optionally, the time-frequency domain position of the at least one measurement resource can be configured or indicated by the network through high-layer signaling (such as RRC signaling or MAC signaling) / DCI, and whether the at least one measurement resource belongs to the first resource type or the second resource type is also configured or indicated by the network device through high-layer signaling / DCI. In this way, since the same resource type to which the at least one measurement resource belongs is indicated by the network, this indicates that the network expects the terminal device to be able to report the channel measurement results or interference measurement results of this resource type through CSI, so that the network can perform accurate channel assessment or interference assessment on this resource type.

[0189] For example, taking the measurement resource as a periodic CSI-RS resource, the network device sends configuration information to the terminal device. The configuration information is used to configure the periodic CSI-RS resource. The configuration information is carried by high-layer signaling and includes period information, offset information, and resource type information. The period information and offset information are used to configure the time-frequency domain position of the periodic CSI-RS resource, and the resource type information is used to indicate the resource type of the periodic CSI-RS resource.

[0190] Optionally, the at least one measurement resource belongs to the first resource type or the second resource type, which means that all resource positions (such as time domain positions and / or frequency domain positions) of the at least one measurement resource are within the resources belonging to the first resource type or the second resource type.

[0191] It should be noted that the network configures the time-frequency domain location of the at least one measurement resource and indicates that all time-frequency domain locations of the at least one measurement resource are within resources belonging to the first resource type or the second resource type, thereby configuring / indicating a network-desired resource type for CSI measurement. In this way, since all resource locations of the measurement resources are within resources of the same resource type, the channel measurement results or interference measurement results measured by the measurement resources can better reflect the resource type.

[0192] For example, if the measurement resource is a periodic CSI-RS resource, the network device will configure period information, offset information, and resource type information for the terminal device. All time-frequency domain positions of the periodic CSI-RS resource configured by the period information and offset information are within the resources of the first resource type indicated by the resource type information.

[0193] Optionally, the at least one measurement resource belongs to the first resource type or the second resource type, which means that part of the resource position (such as the time domain position and / or the frequency domain position) of the at least one measurement resource is within the resource belonging to the first resource type or the second resource type.

[0194] It should be noted that the network configures the time-frequency domain location of the at least one measurement resource and indicates that only a portion of the time-frequency domain location of the at least one measurement resource needs to be within resources belonging to the first resource type or the second resource type. In this way, even though only a portion of the time-frequency domain location is within resources belonging to the first resource type or the second resource type, the terminal device can use the measurement resources at these time-frequency domain locations to perform channel measurement or interference measurement to separately reflect one resource type, avoiding resource waste caused by discarding measurement resources at all time-frequency domain locations.

[0195] Optionally, the resource type of the channel measurement resource (CMR) in the at least one measurement resource and the resource type of the interference measurement resource (IMR) in the at least one measurement resource are the same.

[0196] It should be noted that since the at least one measurement resource may include channel measurement resources and interference measurement resources, the channel measurement resources are used for channel measurement, and the interference measurement resources are used for interference measurement. Therefore, in order to ensure that the channel measurement results and the interference measurement results can individually reflect the same resource type, the resource type to which the channel measurement resources belong and the resource type to which the interference measurement resources belong need to be the same, that is, either they are the same first resource type or the same second resource type.

[0197] [Scheme 2]

[0198] In "Solution 2", this embodiment considers that the measurement resources configured for CSI measurement belong to multiple resource types, but the measurement resources associated with CSI reporting belong to one resource type among the multiple resource types.

[0199] In this way, although the measurement resources configured for CSI measurement belong to multiple resource types, since the channel measurement result or interference measurement result reported by the CSI is obtained by performing channel measurement or interference measurement based on the measurement resources associated with the CSI report, as long as the measurement resources associated with the CSI report belong to one resource type, the channel measurement result or interference measurement result reported by the CSI can also independently reflect one resource type.

[0200] Optionally, the multiple resource types to which the measurement resources configured for CSI measurement belong are configured by the network.

[0201] Optionally, the measurement resource associated with the CSI report belongs to a resource type configured by the network.

[0202] For example, in the case of interaction between a network device and a terminal device, the network device sends first information, which is used to indicate a resource type, from among multiple resource types, to which the measurement resource associated with the CSI report belongs. Correspondingly, the terminal device receives the first information. The first information may be carried by higher-layer signaling (e.g., RRC signaling, MAC signaling) / DCI, etc.

[0203] In the following, this embodiment is described by taking as an example that the multiple resource types include a first resource type and a second resource type, and the measurement resource associated with the CSI reporting belongs to the first resource type or the second resource type.

[0204] Regarding measurement resources configured for CSI measurement, taking the interaction between a network device and a terminal device as an example, the network device sends information for configuring at least one measurement resource for CSI measurement; in response, the terminal device receives the information and obtains the at least one measurement resource based on the information. The network device sends first information indicating, from among multiple resource types, a resource type to which the measurement resource associated with the CSI report belongs; in response, the terminal device receives the first information.

[0205] The at least one measurement resource belongs to both the first resource type and the second resource type, the at least one measurement resource includes a measurement resource associated with CSI reporting, and the measurement resource associated with CSI reporting belongs to the first resource type or the second resource type, so that the measurement resource associated with CSI reporting belongs to one resource type.

[0206] Optionally, the at least one measurement resource belongs to both the first resource type and the second resource type, and is configured or indicated by the network device through high-layer signaling / DCI. In this way, the network configures the resource type to which the at least one measurement resource belongs.

[0207] Optionally, the at least one measurement resource belongs to both the first resource type and the second resource type, which means that the at least one measurement resource has both a resource location within the resources belonging to the first resource type and a resource location within the resources belonging to the second resource type.

[0208] It should be noted that the network will configure the time-frequency domain position of the at least one measurement resource, and indicate that part of the time-frequency domain position of the at least one measurement resource is within the resource belonging to the first resource and another part of the time-frequency domain position is within the resource belonging to the second resource, thereby configuring / indicating multiple resource types expected by the network for CSI measurement.

[0209] Optionally, the measurement resource associated with the CSI report belongs to the first resource type or the second resource type, and is configured or indicated by the network device through high-layer signaling / DCI.

[0210] In this way, since the resource type to which the measurement resource associated with the CSI report belongs is indicated by the network, this means that the network expects the terminal device to be able to report the channel measurement results or interference measurement results of this resource type through CSI so that the network can perform accurate channel evaluation or interference evaluation on this resource type.

[0211] Optionally, the measurement resources associated with the CSI reporting belong to the first resource type or the second resource type, which means that all resource locations of the measurement resources associated with the CSI reporting are within the resources belonging to the first resource type or the second resource type.

[0212] It should be noted that the network configures the time-frequency domain locations of the measurement resources associated with the CSI report and indicates that all time-frequency domain locations of the measurement resources associated with the CSI report are within resources belonging to the first resource type or the second resource type, thereby configuring / indicating a network-desired resource type for the CSI report. In this way, since all resource locations of the measurement resources associated with the CSI report are within resources of the same resource type, the channel measurement results or interference measurement results measured by the measurement resources can better reflect the resource type.

[0213] Optionally, the measurement resources associated with the CSI reporting belong to the first resource type or the second resource type, which means that part of the measurement resources associated with the CSI reporting are located within the resources belonging to the first resource type or the second resource type.

[0214] It should be noted that the network will configure the time-frequency domain positions of the measurement resources associated with the CSI report, and indicate that only part of the time-frequency domain positions of the measurement resources associated with the CSI report need to be within the resources belonging to the first resource type or the second resource type. In this way, although only part of the time-frequency domain positions of the time-frequency domain positions associated with the CSI report are within the resources belonging to the first resource type or the second resource type, the terminal device can also use the measurement resources at this part of the time-frequency domain positions associated with the CSI report to perform channel measurement or interference measurement to separately reflect one resource type, thereby avoiding resource waste caused by discarding the measurement resources at all time-frequency domain positions associated with the CSI report.

[0215] Optionally, the resource type to which the channel measurement resource (CMR) associated with the CSI report belongs is the same as the resource type to which the interference measurement resource (IMR) associated with the CSI report belongs.

[0216] It should be noted that since the measurement resources associated with the CSI report may include channel measurement resources and interference measurement resources, the channel measurement resources are used for channel measurement, and the interference measurement resources are used for interference measurement. Therefore, in order to ensure that the channel measurement results and the interference measurement results can separately reflect the same resource type, the resource type to which the channel measurement resources belong and the resource type to which the interference measurement resources belong need to be the same, that is, either the first resource type or the second resource type.

[0217] [Scheme 3]

[0218] Unlike the above-mentioned "Scheme 2" in which the measurement resources associated with the CSI report are explicitly configured / explicitly indicated to belong to one of multiple resource types, in "Scheme 3", this embodiment considers that the measurement resources configured for CSI measurement belong to multiple resource types, and implicitly configures / implicitly indicates that the measurement resources associated with the CSI report belong to one of multiple resource types.

[0219] In specific implementation, this embodiment may determine the resource type of the measurement resource associated with the CSI report according to the resource type of one of the measurement resources configured for CSI measurement, thereby realizing implicit configuration / implicit indication.

[0220] For example, the resource type of a channel measurement resource in the measurement resources configured for CSI measurement is used to implicitly configure / implicitly indicate the resource type of the measurement resource associated with CSI reporting.

[0221] That is, the resource type to which the channel measurement resource belongs is used as the resource type of the measurement resource associated with the CSI report, so that the resource type of the measurement resource associated with the CSI report is the same as the resource type to which the channel measurement resource belongs, thereby realizing implicit configuration / implicit indication.

[0222] Optionally, the multiple resource types to which the measurement resources configured for CSI measurement belong are configured by the network. This embodiment is described below using an example where the multiple resource types include a first resource type and a second resource type, and the measurement resources associated with CSI reporting belong to the first resource type or the second resource type.

[0223] Regarding the measurement resources configured for CSI measurement, taking the interaction between a network device and a terminal device as an example, the network device sends at least one measurement resource for CSI measurement; correspondingly, the terminal device obtains the at least one measurement resource.

[0224] The at least one measurement resource belongs to both the first resource type and the second resource type, the at least one measurement resource includes a measurement resource associated with CSI reporting, the resource type of the measurement resource associated with CSI reporting is the same as the resource type of the first measurement resource, the first measurement resource is a channel measurement resource in the at least one measurement resource, and the first measurement resource belongs to the first resource type or the second resource type.

[0225] In this way, the resource type to which the first measurement resource belongs is used to implicitly configure / implicitly indicate that the measurement resource associated with the CSI report belongs to the first resource type or the second resource type, so that the measurement resource associated with the CSI report belongs to one resource type.

[0226] Optionally, the at least one measurement resource belongs to both the first resource type and the second resource type, and is configured or indicated by the network device through high-layer signaling / DCI. In this way, the network configures the resource type to which the at least one measurement resource belongs.

[0227] Optionally, the first measurement resource is indicated or configured by the network device through high-layer signaling / DCI, or is specified by a protocol, or is determined autonomously by the terminal device, or is pre-configured.

[0228] Optionally, the first measurement resource is a channel measurement resource whose time domain position within the first measurement resource set is closest to / adjacent to the CSI reference resource corresponding to the CSI report; wherein, the first measurement resource set is composed of measurement resources in the at least one measurement resource that are located before the time domain position of the CSI reference resource corresponding to the CSI report.

[0229] It should be noted that, in conjunction with the content of the above-mentioned "CSI reference resource", the time domain position of the measurement resource associated with the CSI report may be located before the CSI reference resource corresponding to the CSI report, that is, the measurement resource located before the CSI reference resource corresponding to the CSI report can be used as the measurement resource associated with the CSI report. Therefore, in this embodiment, from the measurement resources located before the time domain position of the CSI reference resource corresponding to the CSI report in the at least one measurement resource, the resource type of a channel measurement resource (that is, the first measurement resource) whose time domain position is closest to / adjacent to the CSI reference resource corresponding to the CSI report can be used as the resource type of the measurement resource associated with the CSI report. At the same time, the measurement resource associated with the CSI report may include the first measurement resource.

[0230] Optionally, the first measurement resource is a channel measurement resource having a minimum index / maximum index among the at least one measurement resource.

[0231] It should be noted that each channel measurement resource in the at least one measurement resource has a unique index. Therefore, this embodiment can use the resource type of a channel measurement resource (i.e., the first measurement resource) with the minimum index / maximum index in the at least one measurement resource as the resource type of the measurement resource associated with the CSI report, which is easy to implement.

[0232] Optionally, the first measurement resource is a channel measurement resource with a minimum index in the first measurement resource set.

[0233] It should be noted that, in conjunction with the above-mentioned "CSI reference resource," the time domain position of the measurement resource associated with the CSI report may be located before the CSI reference resource corresponding to the CSI report. That is, the measurement resource located before the CSI reference resource corresponding to the CSI report can be used as the measurement resource associated with the CSI report. Therefore, this embodiment can use the resource type of the channel measurement resource (i.e., the first measurement resource) with the smallest index / largest index from the measurement resources located before the time domain position of the CSI reference resource corresponding to the CSI report in the at least one measurement resource as the resource type of the measurement resource associated with the CSI report, which is easy to implement.

[0234] Optionally, the resource type of the channel measurement resource associated with the CSI report and the resource type of the interference measurement resource associated with the CSI report are the same.

[0235] [Scheme 4]

[0236] In "Scheme 4", this embodiment further analyzes the effective downlink time slot and n based on the above "Scheme 1", "Scheme 2" and "Scheme 3". CSI_ref .

[0237] Combined with the above content of "CSI reference resources", it can be seen that the CSI reference resources corresponding to CSI reporting need to be located in the valid downlink time slot. Since the measurement resources associated with CSI reporting may belong to different resource types, the valid downlink time slot needs to be redefined.

[0238] Optionally, if the measurement resource associated with the CSI report belongs to the first resource type, the CSI reference resource corresponding to the CSI report is located in the first valid downlink time slot; wherein, the first valid downlink time slot includes at least one first downlink symbol or a first flexible symbol, and / or the first valid downlink time slot is not within the measurement interval; the first downlink symbol refers to a downlink symbol belonging to the first resource type, and the first flexible symbol refers to a flexible symbol belonging to the first resource type.

[0239] For example, taking the first resource type as SBFD as an example, the first valid downlink timeslot includes at least one SBFD downlink symbol or SBFD flexible symbol, and / or the first valid downlink timeslot is not within the measurement interval.

[0240] Optionally, if the measurement resource associated with the CSI report belongs to the second resource type, the CSI reference resource corresponding to the CSI report is located in the second valid downlink time slot; wherein, the second valid downlink time slot includes at least one second downlink symbol or a second flexible symbol, and / or the second valid downlink time slot is not within the measurement interval; the second downlink symbol refers to a downlink symbol belonging to the second resource type, and the second flexible symbol refers to a flexible symbol belonging to the second resource type.

[0241] For example, taking the second resource type as non-SBFD, the second valid downlink time slot includes at least one non-SBFD downlink symbol or non-SBFD flexible symbol, and / or the second valid downlink time slot is not within the measurement interval.

[0242] Combined with the content in the above “CSI Reference Resources”, we can know that n CSI_ref The definition of is related to the CSI reference resource corresponding to the CSI report being in the valid downlink time slot. Since the valid downlink time slot needs to be redefined, n CSI_ref It also needs to be redefined. For the convenience of description, the following is CSI_refThe first parameter is used as an example for description, wherein the first parameter may represent the time slot offset between the downlink time slot corresponding to the uplink time slot where the CSI is reported and the first valid downlink time slot or the second valid downlink time slot.

[0243] Optionally, for the measurement resource associated with the CSI report belonging to the first resource type, if the CSI report is periodic or semi-continuous, and the measurement resource associated with the CSI report includes a channel measurement resource, the first parameter is greater than or equal to The minimum value of the CSI reference resource corresponding to the CSI report is located in the first valid downlink time slot.

[0244] Optionally, for the measurement resource associated with the CSI report belonging to the second resource type, if the CSI report is periodic or semi-continuous, and the measurement resource associated with the CSI report includes a channel measurement resource, the first parameter is greater than or equal to The minimum value of the CSI reference resource corresponding to the CSI report is located in the second valid downlink time slot.

[0245] Optionally, for the measurement resource associated with the CSI report belonging to the first resource type, if the CSI report is periodic or semi-continuous, and the measurement resource associated with the CSI report includes multiple channel measurement resources, the first parameter is greater than or equal to The minimum value of the CSI reference resource corresponding to the CSI report is located in the first valid downlink time slot.

[0246] Optionally, for the measurement resource associated with the CSI report belonging to the second resource type, if the CSI report is periodic or semi-continuous, and the measurement resource associated with the CSI report includes multiple channel measurement resources, the first parameter is greater than or equal to The minimum value of the CSI reference resource corresponding to the CSI report is located in the second valid downlink time slot.

[0247] Optionally, if the measurement resource associated with the CSI report belongs to the first resource type, if the CSI report is non-periodic and the DCI used to trigger the CSI report is in the same time slot as the CSI report, the first valid downlink time slot is the time slot where the DCI is located.

[0248] Optionally, if the measurement resource associated with the CSI report belongs to the second resource type, if the CSI report is non-periodic and the DCI used to trigger the CSI report is in the same time slot as the CSI report, the second effective downlink time slot is the time slot where the DCI is located.

[0249] Optionally, for the measurement resource associated with the CSI report, which belongs to the first resource type, if the CSI report is non-periodic and the DCI used to trigger the CSI report is not in the same time slot as the CSI report, the first parameter is greater than or equal to The minimum value of the CSI reference resource corresponding to the CSI report is located in the first valid downlink time slot.

[0250] Optionally, for the measurement resource associated with the CSI report belonging to the second resource type, if the CSI report is non-periodic and the DCI used to trigger the CSI report is not in the same time slot as the CSI report, the first parameter is greater than or equal to The minimum value of the CSI reference resource corresponding to the CSI report is located in the second valid downlink time slot.

[0251] [Scheme 5]

[0252] In "Solution 5," this embodiment further considers reporting of measurement results (such as channel measurement results and / or interference measurement results) based on the above-mentioned "Solution 1," "Solution 2," "Solution 3," and "Solution 4." The measurement results may be obtained based on measurement resources associated with the CSI report, and the measurement results are carried in the CSI report.

[0253] Optionally, the measurement result includes CSI information, where the CSI information may include at least one of the following: layer 1 reference signal received power (L1-RSRP), layer 1 signal-to-noise and interference ratio (L1-SINR), CSI-related quantities, etc.

[0254] Optionally, the CSI-related parameters may include at least one of the following: CSI-RS resource indicator (CSI-RS resource indicator, CRI), SSB resource indicator index (SS / PBCH block resource indicator, SSBRI), rank indicator index (rank indicator, RI), precoding matrix indicator index (precoding matrix indicator, PMI), CQI, layer indicator index (layer indicator, LI), capability index (capability index), time-domain channel properties (time-domain channel properties, TDCP), etc.

[0255] During the measurement result reporting process, the network device may configure one or more CSI reports to the terminal device, and the measurement resources associated with each CSI report belong to one of multiple resource types. The terminal device may need to report the measurement results obtained by measuring the measurement resources associated with each CSI report to the network device through a CSI report.

[0256] Since the resource types of the measurement resources associated with each CSI report may be the same or different, the measurement results obtained by measuring the measurement resources of different resource types will also be different.

[0257] In the following description of this embodiment, the multiple resource types include a first resource type and a second resource type, and the CSI report includes a first measurement result and / or a second measurement result.

[0258] Regarding the measurement resources configured for CSI measurement, taking the interaction between a network device and a terminal device as an example, the network device sends at least one measurement resource for CSI measurement; correspondingly, the terminal device obtains the at least one measurement resource.

[0259] If the at least one measurement resource includes a second measurement resource, the second measurement resource belongs to the first resource type, and the second measurement resource is associated with the first CSI report, the terminal device may obtain a first measurement result based on the second measurement resource and send a CSI report to the network device, where the CSI report includes the first measurement result. In this way, after obtaining the first measurement result, the network device can perform accurate channel assessment or interference assessment for the first resource type based on the first measurement result.

[0260] If the at least one measurement resource includes a third measurement resource, the third measurement resource belongs to the second resource type, and the third measurement resource is associated with a second CSI report, the terminal device may obtain a second measurement result based on the third measurement resource and send a CSI report to the network device, where the CSI report includes the second measurement result. In this way, after the network device obtains the second measurement result, the network device can perform accurate channel assessment or interference assessment for the first resource type based on the second measurement result.

[0261] If the at least one measurement resource includes a second measurement resource and a third measurement resource, the terminal device can obtain a first measurement result based on the second measurement resource measurement, and obtain a second measurement result based on the third measurement resource measurement. At this time, the terminal device can send a CSI report twice, one CSI report includes the first measurement result, and the other CSI report includes the second measurement result. In addition, in order to save signaling / resource overhead, the terminal device can send a CSI report, and the CSI report includes the first measurement result and the second measurement result. Since the first measurement result and the second measurement result can each separately reflect a resource type, after the network device obtains the first measurement result and the second measurement result, the network device can perform accurate channel evaluation or interference evaluation on the first resource type based on the first measurement result, and perform accurate channel evaluation or interference evaluation on the second resource type based on the second measurement result.

[0262] 5. Example of a communication method

[0263] In conjunction with the above content, the following describes an example of a communication method according to an embodiment of the present application, taking the interaction between a network device and a terminal device as an example. The terminal device may be a chip, a chip module, or a communication module, and the network device may be a chip, a chip module, or a communication module.

[0264] FIG4 is a flow chart of a communication method according to an embodiment of the present application, which specifically includes the following steps:

[0265] S410: The network device sends first information, where the first information is used to indicate a resource type of a measurement resource.

[0266] Correspondingly, the terminal device receives the first information.

[0267] S420. The terminal device performs measurement according to the first information and reports CSI.

[0268] It can be seen that this embodiment indicates the resource type of the measurement resource associated with the CSI report through the first information. Since the channel measurement result or interference measurement result of the CSI report is obtained by performing channel measurement or interference measurement based on the measurement resource associated with the CSI report, when the measurement resource associated with the CSI report belongs to a resource type, the channel measurement result or interference measurement result of the CSI report can independently reflect a resource type.

[0361] Optionally, the communication device 600 may further include a receiving unit, wherein the receiving unit may be a module unit for receiving and processing signals, information, etc., and is not specifically limited thereto.

[0362] Optionally, the communication device 600 may further include a storage unit for storing computer program codes or instructions executed by the communication device 600. The storage unit may be a memory.
