Description

Technical Field

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

[0002] In a Time Division Duplexing (TDD) system, all frequency-domain resources of a TDD carrier have the same transmission direction at the same moment, that is, they are all uplink or downlink. Thus, the TDD system has the following resource types: different frequency-domain resources on the same TDD carrier adopt the same uplink and downlink time slot ratio. However, there is a phenomenon that the uplink and downlink time slot ratio cannot be flexibly configured for such resource types.

[0003] With the development and popularization of information and communication technologies, service requirements show a trend of diversification and personalization. Application scenarios and service requirements of different vertical industries are also different. For example, scenarios such as home, office, and industry have different requirements for network bandwidth, transmission rate, and latency. In this case, in order to better meet the transmission requirements of various services and different terminal devices, resources belonging to multiple resource types may coexist in a communication system, such as low-latency resources, high-reliability resources, high-rate resources, etc., so as to support different uplink and downlink transmission requirements.

[0004] 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 separately reflect a certain resource type, resulting in the network being unable to accurately perform channel evaluation or interference evaluation for a certain resource type alone.

[0088] II. A Communication Method

[0089] 1. Description

[0090] In order to better meet the transmission requirements of various services and different terminal devices, there may be resources belonging to multiple resource types in the communication system at the same time.

[0091] For example, in a Time Division Duplexing (TDD) system, all frequency-domain resources of a TDD carrier need to have the same transmission direction at the same moment, that is, either all uplink or all downlink. That is to say, the TDD system has the following resource types: different frequency-domain resources on the same TDD carrier adopt the same uplink / downlink time slot ratio. However, due to the inflexible configuration of the single downlink time slot ratio, this type of resource cannot meet the differentiated requirements of different services for uplink / downlink transmission. Therefore, the communication system introduces the following resource type: different frequency-domain resources on the same TDD carrier adopt different uplink / downlink time slot ratios, enabling this type of resource to flexibly configure the uplink / downlink time slot ratio. Therefore, to meet the transmission requirements of various services and different terminal devices, the communication system may configure resources of the above two resource types for the terminal device.

[0092] During the CSI measurement / CSI reporting process, the measurement resources configured by the network for CSI measurement / CSI reporting may belong to multiple resource types at the same time. For example, one is that different frequency-domain resources on the same TDD carrier adopt the same uplink / downlink time slot ratio, and the other is that different frequency-domain resources on the same TDD carrier adopt different uplink / downlink time slot ratios. At this time, the channel measurement results or interference measurement results measured by the measurement resources may not be able to separately reflect a certain resource type, resulting in the network being unable to accurately evaluate the channel or interference of a certain resource type alone.

[0093] Based on this, this embodiment considers that the measurement resources configured for CSI measurement belong to one of the multiple resource types. Since the measurement resources configured for CSI measurement include the measurement resources associated with CSI reporting, the measurement resources associated with CSI reporting also belong to the same resource type. Or, 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.

[0094] Since the channel measurement results or interference measurement results of CSI reporting are obtained by performing channel measurement or interference measurement according to the measurement resources associated with this CSI reporting, when the measurement resources associated with this CSI reporting belong to one resource type, the channel measurement results or interference measurement results of this CSI reporting can separately reflect one resource type. In this way, after the network device obtains the channel measurement results or the interference measurement results, the network device can accurately evaluate the channel or interference of one resource type alone, so as to adapt to the scenario where the network expects to only evaluate the channel or interference of one resource type.

[0095] 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-downlink time slot ratio, different frequency-domain resources on the same TDD carrier using different uplink-downlink time slot ratios, subband full duplex (SBFD), non-subband full duplex (non-SBFD), non-overlapping full duplex, overlapping full duplex, etc. Among them, SBFD means that different subbands of the same carrier use different uplink-downlink time slot ratios; non-SBFD means that different subbands of the same carrier use the same uplink-downlink time slot ratio; non-overlapping full duplex means that uplink and downlink are allowed to be carried out simultaneously on non-overlapping subbands within the same carrier; overlapping full duplex means that uplink and downlink are allowed to be carried out simultaneously on overlapping / identical subbands within the same carrier.

[0096] For example, in Figure 2 , uplink and downlink are allowed to be carried out simultaneously on non-overlapping subbands within the same carrier; in Figure 2 (a), different subbands of the same carrier use the same uplink-downlink time slot ratio, and in Figure 2 (b), (c) and (d), different subbands of the same carrier use different uplink-downlink time slot ratios.

[0097] 2. SBFD

[0098]

Symbols

[0099]

SBFD

[0100] In order to avoid the limitations of the uplink-downlink time slot ratio in the TDD system as much as possible and consider the implementation complexity of network devices, this embodiment considers SBFD to enable uplink transmission and downlink transmission to be supported at the same time, improving spectrum utilization and flexibility.

[0101] Optionally, the network configures SBFD resources through network signaling (such as DCI, MAC signaling, MAC CE, system information, dedicated information, UE dedicated signaling, etc.). Among them, SBFD resources can include time-domain SBFD resources and frequency-domain SBFD resources.

[0102] Time-domain SBFD resources can be understood as SBFD resources in the time domain, which can include SBFD symbols, SBFD time slots, SBFD mini time slots, SBFD subframes, etc.

[0103] 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, SBFD uplink subbands can be used for uplink transmission or uplink reception, and SBFD downlink subbands can be used for downlink transmission.

[0104]

SBFD Symbol

[0105] The SBFD symbol can be understood as a symbol that has been configured to allow SBFD operations or a symbol for which SBFD operations have been configured. That is, whether the original symbol supports uplink transmission or downlink transmission, its property has changed due to the configuration of SBFD operations.

[0106] Of course, the SBFD uplink sub-band can be referred to as the "uplink sub-band"; the SBFD downlink sub-band can be referred to as the "downlink sub-band". Additionally, in this application, the "SBFD symbol" can also be replaced with "SBFD time slot", "SBFD mini time slot", "SBFD sub-frame", etc. The meanings expressed by each of them can be known analogously according to the "SBFD symbol", and no specific restrictions are imposed on this.

[0107] Optionally, there is a guard band between the uplink sub-band and the downlink sub-band. In this way, interference between the uplink and downlink can be avoided as much as possible through the guard band.

[0108] Optionally, the SBFD symbol includes SBFD downlink symbols, SBFD uplink symbols, and SBFD flexible symbols.

[0109] An SBFD downlink symbol refers to a downlink symbol that has been configured to allow SBFD operations or a downlink symbol for which SBFD operations have been configured. Therefore, the SBFD downlink symbol can support both downlink transmission and uplink transmission.

[0110] For example, the network can configure a part of the uplink sub-band in the frequency band of the downlink symbol in the original time slot through network signaling, so that the downlink symbol can support both uplink transmission and downlink transmission, thereby implementing the configuration of SBFD operations.

[0111] An SBFD uplink symbol refers to an uplink symbol that has been configured to allow SBFD operations or an uplink symbol for which SBFD operations have been configured. Therefore, the SBFD uplink symbol can support both uplink transmission and downlink transmission.

[0112] For example, the network can configure a part of the downlink sub-band in the frequency band of the uplink symbol in the original time slot through network signaling, so that the uplink symbol can support both uplink transmission and downlink transmission, thereby implementing the configuration of SBFD operations.

[0113] An SBFD flexible symbol refers to a flexible symbol that has been configured to allow SBFD operations or a flexible symbol for which SBFD operations have been configured. Therefore, the SBFD flexible symbol can be configured by the network to support both uplink transmission and downlink transmission, that is, support both uplink and downlink transmissions simultaneously.

[0114] For example, the network can configure a part of the uplink sub-band and a part of the downlink sub-band in the frequency band of the flexible symbol within the original time slot, so that the flexible symbol can support uplink transmission and downlink transmission, thereby implementing the configuration of the SBFD operation.

[0115]

non-SBFD symbol

[0116] To distinguish from the "SBFD symbol", the non-SBFD symbol can be understood as a symbol that is not configured for the SBFD operation, or the original symbol within the time slot, or a symbol that does not allow the SBFD operation.

[0117] That is to say, the attribute of whether the original symbol supports uplink transmission or downlink transmission has not changed due to the non-configuration of SBFD. That is, the original downlink symbol can only support downlink transmission; the original uplink symbol can only support uplink transmission; the original flexible symbol can be configured by the network to support either uplink transmission or downlink transmission, that is, it only supports one transmission mode.

[0118] It should be noted that in order to distinguish from the SBFD symbol that appears above, this application introduces "non-SBFD downlink symbol", "non-SBFD uplink symbol" and "non-SBFD flexible symbol".

[0119] Optionally, the non-SBFD symbol, including the non-SBFD downlink symbol, the non-SBFD uplink symbol, and the non-SBFD flexible symbol, can include the original downlink symbol, the original uplink symbol, and the original flexible symbol.

[0120] The non-SBFD downlink symbol refers to a downlink symbol that is not configured for the SBFD operation, or a downlink symbol and not configured for the SBFD operation. That is to say, the non-SBFD downlink symbol is the original downlink symbol. Therefore, the non-SBFD downlink symbol can only support downlink transmission.

[0121] The non-SBFD uplink symbol refers to an uplink symbol that is not configured for the SBFD operation, or an uplink symbol and not configured for the SBFD operation. That is to say, the non-SBFD uplink symbol is the original uplink symbol. Therefore, the non-SBFD uplink symbol can only support uplink transmission.

[0122] The non-SBFD flexible symbol refers to a flexible symbol that is not configured for the SBFD operation, or a flexible symbol and not configured for the SBFD operation. That is to say, the non-SBFD flexible symbol is the original flexible symbol. Therefore, the non-SBFD flexible symbol can be configured by the network to support either uplink transmission or downlink transmission, that is, it only supports one transmission mode.

[0123] 3. CSI-related Configuration

[0124]

Measurement Resources

[0125] CSI-related configuration may include CSI report configuration and / or CSI resource configuration, which may be defined by the higher-layer parameter CSI-MeasConfig (CSI measurement configuration). Among them, CSI-MeasConfig may indicate (include / configure / carry) the following two higher-layer parameters: CSI-ResourceConfig (CSI resource configuration) and CSI-ReportConfig (CSI report configuration).

[0126] In addition, since CSI-ReportConfig may indicate / include CSI-ResourceConfigId (CSI resource configuration identifier), CSI-ResourceConfig is associated (corresponds / maps) with CSI-ReportConfig through CSI-ResourceConfigId.

[0127] CSI-ReportConfig can be used for the configuration of CSI reporting, that is, to configure CSI reports.

[0128] CSI-ResourceConfig can be used to configure the resources for CSI measurement, such as CSI-RS. In addition, CSI-ResourceConfig can configure CSI-Resource-Set (CSI resource set), and CSI-Resource-Set can contain the most basic CSI-RS resources (such as CSI-RS-Resource).

[0129] CSI-Resource-Set may 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), CSI-SSB-ResourceSet (synchronization signal block SSB resource set).

[0130] NZP-CSI-RS-ResourceSet can be used for channel measurement and / or interference measurement; CSI-IM-ResourceSet can be used for interference measurement; CSI-SSB-ResourceSet can be used for channel measurement.

[0131] For CSI-ResourceConfig and / or NZP-CSI-RS-ResourceSet, one or more NZP CSI-RS resource sets can be configured. Each NZP CSI-RS resource set can include K (K≥1) NZP CSI-RS resources.

[0132] For example, the network device sends 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.

[0133] In summary, a measurement resource can be a CSI resource setting, a CSI resource set, or a CSI resource. Among them, 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 CSI-RS resource, CSI-IM resource, and 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; an SSB resource can be used for channel measurement.

[0134] 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.

[0135]

Time domain behavior

[0136] The time-domain behavior can include periodic, semi-persistent, and aperiodic. Taking CSI-RS as an example, it is illustrated below.

[0137] 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 higher-layer parameters (such as the resource type resourceType).

[0138] For periodic CSI-RS, after the network device configures the information of periodic CSI-RS and the configuration takes effect, the network device will send CSI-RS to the terminal device periodically.

[0139] For aperiodic CSI-RS, after the network device configures the information of aperiodic CSI-RS, the network device will not immediately send CSI-RS. Instead, it will first send a signaling to notify the terminal device and then send aperiodic CSI-RS to the terminal device.

[0140] For non-semi-persistent CSI-RS, after the network device configures the information of semi-persistent CSI-RS, the network device will not immediately send CSI-RS. Instead, it will first send a 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. Among them, once the network device triggers the transmission of semi-persistent CSI-RS, it will send CSI-RS periodically unless the network device issues a deactivation signaling.

[0141] 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), and the time-domain behavior of CSI reporting can be indicated by higher-layer parameters (such as the reporting configuration type (reportConfigType)).

[0142] For aperiodic CSI reporting and semi-persistent CSI reporting carried on PUSCH, the network device will also configure the higher-layer parameters TriggerState and the higher-layer parameter reportTriggerSize to cooperate with the CSI request field in the downlink control information (DCI).

[0143] For periodic CSI reporting, after configuring the periodic CSI-RS Resource and Report parameters through RRC messages (or RRC signaling), it will take effect immediately without activating / triggering CSI-RS transmission and CSI reporting through MAC-CE / DCI.

[0144] For semi-persistent CSI reporting carried on PUCCH, if semi-persistent CSI-RS transmission is configured through RRC messages, CSI-RS transmission needs to be activated first through MAC CE1, and then CSI reporting needs to be activated through MAC CE2; if periodic CSI-RS transmission is configured through RRC messages, CSI-RS transmission does not need to be activated through MAC CE1, and only CSI reporting needs to be activated through MAC CE2.

[0145] For semi-persistent CSI reporting carried on PUSCH, if semi-persistent CSI-RS transmission is configured through RRC messages, CSI-RS transmission needs to be activated first through MAC CE1, and then CSI reporting needs to be triggered through DCI; if periodic CSI-RS transmission is configured through RRC messages, CSI-RS transmission does not need to be activated through MAC CE1, and only CSI reporting needs to be triggered through DCI.

[0146] It should be noted that for DCI, this DCI can be DCI format 0_1 scrambled with SP-CSI-RNTI (semi-persistent CSI-RNTI), and the CSI request field in this DCI can be associated with the corresponding trigger state (TriggerState) through the setting of the codepoint. The associated CSI-ReportConfig will be defined in this TriggerState, so that the CSI-ReportConfig associated with the semi-persistent CSI reporting on PUSCH can be found through this TriggerState.

[0147] For aperiodic CSI reporting, aperiodic CSI reporting is triggered by DCI, and its process is similar to the above semi-persistent CSI reporting. When associating the corresponding TriggerState through the codepoint of the CSI request field in DCI format 0_1 / 0_2, it is different from the DCI trigger in the above semi-persistent CSI reporting. If the value of this CSI request field is 0, it means that triggering semi-periodic CSI reporting is not required; if the value of the CSI request field is 1, it means that the aperiodic CSI reporting associated with TriggerState 1 is triggered, and so on.

[0148]

CSI reporting band

[0149] The reportFreqConfiguration in CSI-ReportConfig is used to indicate the frequency granularity of CSI reporting.

[0150] The CSI reporting setting configuration can define the CSI reporting band as a subset of subbands in a bandwidth part (BWP). That is, the active BWP can be divided into multiple subbands, and a subset (i.e., some subbands) of these multiple subbands can be defined as the CSI reporting band.

[0151] Optionally, reportFreqConfiguration can indicate that the csi-ReportingBand, as a continuous or discontinuous subset of subbands in the BWP, should report CSI.

[0152] Optionally, reportFreqConfiguration can indicate that wideband CQI reporting or subband CQI reporting can be configured by a higher layer parameter (such as the CQI format indicator cqi-FormatIndicator). When wideband CQI reporting is configured, a wideband CQI is reported for each codeword of the entire CSI reporting band. When subband CQI reporting is configured, a CQI for each codeword is reported for each subband in the CSI reporting band.

[0153] Optionally, reportFreqConfiguration can indicate that wideband PMI reporting or subband PMI reporting can be configured by a higher layer parameter (such as the PMI format indicator pmi-FormatIndicator). When wideband PMI reporting is configured, a wideband PMI is reported for the entire CSI reporting band. When subband PMI reporting is configured, except for 2 antenna ports, a single wideband indication is reported for the entire CSI reporting band, and a subband indication is reported for each subband in the CSI reporting band. When the subband PMI is configured with 2 antenna ports, a PMI is reported for each subband in the CSI reporting band.

[0154]

CSI reference resource

[0155] It should be noted that a CSI report corresponds to a CSI reference resource. When a network device configures at least one measurement resource for CSI measurement for a terminal device, the at least one measurement resource may include the CSI reference resource corresponding to the CSI report and the measurement resources associated with the CSI report.

[0156] For example, for periodic CSI reporting, CSI is reported periodically, and each CSI report corresponds to a CSI reference resource.

[0157] The CSI reference resource may be a piece of time-frequency resource. The time domain of the CSI reference resource may be a time slot, and the frequency domain of the CSI reference resource may be the frequency granularity of the CSI measurement. For example, when CSI is subband measurement, the frequency domain of the CSI reference resource is subband; when CSI is wideband measurement, the frequency domain of the CSI reference resource is wideband.

[0158] When the uplink time slot where the CSI report is located is time slot n′ (n′ represents the time slot index), the downlink time slot where the CSI reference resource is located is time slot K offset represents a parameter configured by the higher layer, represents the subcarrier spacing configuration in frequency range 1 and K offset = 0, μ DL represents the downlink subcarrier spacing configuration.

[0159] Since the CSI reference resource is a downlink resource, the time domain of the CSI reference resource is a downlink time slot. Thus, time slot n represents the downlink time slot corresponding to time slot n′, and is calculated as follows:

[0160]

[0161] where, μ UL represents the uplink subcarrier spacing configuration, and μ offset,DL represents the downlink time slot offset, and represents the uplink time slot offset.

[0162] n CSI_ref represents the time slot offset between time slot n and the valid downlink time slot where the CSI reference resource is located.

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

[0164] For example, assume that the uplink and downlink subcarrier spacing configurations are the same, i.e., μ DL = μ UL = 0. Starting from the minimum value greater than or equal to let n CSI_ref be calculated to obtain 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, let n CSI_ref be calculated to obtain and determine whether time slot n - 5 is a valid downlink time slot. If time slot n - 5 is a valid downlink time slot, the CSI reference resource is located in time slot n - 5; if time slot n - 5 is not a valid downlink time slot, continue to search forward until a valid downlink time slot is found.

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

[0166] For non-periodic, if the DCI used to trigger the CSI report and the CSI report are in the same time slot, the CSI reference resource is located in the time slot where the DCI is located; otherwise, n CSI_ref is the minimum value greater than or equal to such that the CSI reference resource corresponding to the CSI report is located in a valid downlink time slot, represents the number of symbols included in a time slot, and Z′ represents the processing time for 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 higher-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 the channel quality indicator (CQI)

[0170] Channel measurement essentially depends on the implementation of the terminal device. For example, some terminal devices have very strong capabilities and can meet the target block error rate (BLER) requirements when using a certain modulation and coding scheme (MCS) at a signal-to-interference-plus-noise ratio (SINR) of 10 dB. However, some terminal devices have weaker capabilities and need an SINR of 12 dB to meet the target BLER (the target BLER is configured by the network device) requirements. Therefore, if the SINR measured by two terminal devices is both 10 dB, the values of the reported channel quality indicator (CQI) should be different.

[0171] In addition, even for the same terminal device, different transport block sizes (TBS) of data packets will result in different BLERs. For example, when SINR = 10 dB. If the current transmitted TBS is 1000 bits and a specific MCS is selected for transmission, the BLER is 0.01. If a TBS of 500 bits is used and the same MCS is selected for transmission, the corresponding BLER may be 0.1. The two are different.

[0172] Therefore, when quantifying the CQI, the concept of 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] Suppose the terminal device uses CSI-RS for channel measurement to obtain the channel state, such as SINR. The terminal device will assume that a downlink data packet is transmitted on the CSI reference resource, and the corresponding channel state is the one measured by CSI-RS. At this time, the terminal device selects a CQI from the CQI table, and this CQI can make the BLER less than the target BLER when the assumed transmitted downlink data packet is transmitted in the measured channel state.

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

[0175] The network device can configure at least one measurement resource for CSI measurement to the terminal device. The at least one measurement resource may include the CSI reference resource corresponding to the CSI report and the measurement resources associated with the CSI report. Among them, the time domain position of the measurement resources associated with the CSI report may be before the CSI reference resource corresponding to the CSI report. That is to say, the measurement resources before the CSI reference resource corresponding to the CSI report can be used as the measurement resources associated with the CSI report, and which measurements can be used as the measurement resources associated with the CSI report can be configured through high-layer signaling, protocol regulations, pre-configuration, or determined by the terminal device independently, etc.

[0176] For example, taking the periodic measurement resources as an example, such asFigure 3 As shown in Figure 3 , the measurement resources for a period include the measurement resources associated with CSI reporting, and the time-domain position of the measurement resources associated with CSI reporting is before the CSI reference resources corresponding to the CSI reporting. That is to say, the measurement resources before the CSI reference resources corresponding to the CSI reporting may be used as the measurement resources associated with the CSI reporting. As for which or which resources' measurements can be used as the measurement resources associated with the CSI reporting, the network can further configure it through higher-layer signaling. For example, the network can configure the measurement of the resource closest / latest / adjacent to the CSI reference resource 310 as the measurement resources associated with the CSI reporting.

[0177] 4. CSI Measurement / CSI Reporting

[0178] During the CSI measurement / CSI reporting process, in order to ensure that the channel measurement results or interference measurement results measured by the measurement resources can separately reflect a certain resource type, so that the network can accurately perform channel assessment or interference assessment on a certain resource type separately. The following embodiments will be specifically described from the following multiple solutions. Among them, each solution can be independent of each other, or can be combined and associated with each other, and the same content in different solutions can be referenced to each other, and will not be specifically described again.

[0179]

Solution 1

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

[0181] In this way, since the channel measurement results or interference measurement results of CSI reporting are obtained by performing channel measurement or interference measurement according to the measurement resources associated with the CSI reporting, when the measurement resources configured for CSI measurement belong to one resource type, the channel measurement results or interference measurement results of the CSI reporting can separately reflect the same one resource type.

[0182] Optionally, the one resource type to which the measurement resources configured for CSI measurement belong is configured by the network.

[0183] For example, taking the interaction between a network device and a terminal device as an example, the network device sends a first message, and the first message is used to indicate, from multiple resource types, the one resource type to which the measurement resources configured for CSI measurement belong. Correspondingly, the terminal device receives the first message. Among them, the first message can be carried by higher-layer signaling (such as RRC signaling, MAC signaling) / DCI, etc.

[0184] In the following, this embodiment will be described by taking an example in which 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 uplink / downlink time slot ratios for different frequency domain resources on the same TDD carrier.

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

[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 according to the information. The network device sends a first piece of information, which is used to indicate, from the multiple resource types, a resource type to which the at least one measurement resource belongs; correspondingly, the terminal device receives the first piece of information. Among them, 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 resources associated with CSI reporting, the measurement resources associated with CSI reporting also belong to the same resource type.

[0188] Optionally, the time-frequency domain location of the at least one measurement resource can be configured or indicated by the network through higher 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 higher 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, it means that the network expects the terminal device to perform CSI reporting on the channel measurement results or interference measurement results of this resource type, so that the network can accurately evaluate the channel or interference of this resource type.

[0189] For example, taking the periodic CSI-RS resource as a measurement resource, the network device sends configuration information to the terminal device, and the configuration information is used to configure the periodic CSI-RS resource. Among them, the configuration information is carried by high-layer signaling, and the configuration information includes periodic information, offset information, and resource type information. The periodic information and the 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 to which the periodic CSI-RS resource belongs.

[0190] Optionally, the at least one measurement resource belonging to the first resource type or the second resource type means that all resource positions (such as time domain position and / or frequency domain position) 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 position of the at least one measurement resource, and indicates that all time-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, so as to implement a resource type expected by the network for CSI measurement configuration / indication. In this way, since all resource positions of the measurement resource are within the resources of one resource type, the channel measurement result or interference measurement result measured by the measurement resource can better reflect this resource type.

[0192] For example, taking the periodic CSI-RS resource as a measurement resource, the network device configures periodic information, offset information, and resource type information for the terminal device. Among them, all time-frequency domain positions of the periodic CSI-RS resource configured by the periodic information and the 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 belonging to the first resource type or the second resource type means that some resource positions (such as time domain position and / or frequency domain position) of the at least one measurement resource are within the resources belonging to the first resource type or the second resource type.

[0194] It should be noted that the network configures the time-frequency domain position of the at least one measurement resource, and indicates that only some time-frequency domain positions of the at least one measurement resource need to be within the resources belonging to the first resource type or the second resource type. In this way, although only some time-frequency domain positions 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 these time-frequency domain positions to perform channel measurement or interference measurement to separately reflect a resource type, avoiding resource waste caused by discarding the measurement resources at all time-frequency domain positions.

[0195] Optionally, the resource type to which the channel measurement resource (CMR) in the at least one measurement resource belongs is the same as the resource type to which the interference measurement resource (IMR) in the at least one measurement resource belongs.

[0196] It should be noted that since the at least one measurement resource may include a channel measurement resource and an interference measurement resource, the channel measurement resource is used for channel measurement, and the interference measurement resource is used for interference measurement. Therefore, in order to ensure that the channel measurement result and the interference measurement result can separately reflect the same type of resource, the resource types to which the channel measurement resource belongs and the resource types to which the interference measurement resource belongs need to be the same, that is, either both are the first resource type or both are the second resource type.

[0197]

Solution 2

[0198] In "Solution 2", in this embodiment, it is considered 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.

[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 CSI is obtained by performing channel measurement or interference measurement according to the measurement resources associated with the CSI reporting, as long as the measurement resources associated with the CSI reporting belong to one resource type, the channel measurement result or interference measurement result reported by the CSI can also separately 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 one resource type to which the measurement resources associated with CSI reporting belong is configured by the network.

[0202] For example, taking the interaction between a network device and a terminal device as an example, the network device sends a first message, and the first message is used to indicate one of the multiple resource types to which the measurement resources associated with CSI reporting belong. Correspondingly, the terminal device receives the first message. Among them, the first message can be carried by a high-layer signaling (such as an RRC signaling, a MAC signaling) / DCI, etc.

[0203] Next, this embodiment will be described by taking the multiple resource types including a first resource type and a second resource type, and the measurement resources associated with CSI reporting belonging to the first resource type or the second resource type as an example.

[0204] 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 according to the information. The network device sends first information, and the first information is used to indicate, from multiple resource types, a resource type to which the measurement resource associated with CSI reporting belongs; correspondingly, the terminal device receives the first information.

[0205] Among them, the at least one measurement resource belongs to both a first resource type and a 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 a first resource type and a 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 a first resource type and a second resource type, which means that among the at least one measurement resource, there are resource positions within the resources belonging to the first resource type and resource positions within the resources belonging to the second resource type.

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

[0209] Optionally, the measurement resource associated with CSI reporting 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 a resource type to which the measurement resource associated with CSI reporting belongs is indicated by the network, it means that the network expects the terminal device to perform CSI reporting on the channel measurement result or interference measurement result of this resource type, so that the network can perform accurate channel evaluation or interference evaluation on this resource type.

[0211] Optionally, the measurement resource associated with CSI reporting belongs to the first resource type or the second resource type, which means that all resource positions of the measurement resource associated with 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 positions of the measurement resources associated with CSI reporting, and indicates that all the time-frequency domain positions of the measurement resources associated with CSI reporting are within the resources belonging to the first resource type or the second resource type, so as to implement a resource type expected by the network for CSI reporting configuration / indication. In this way, since all the resource positions of the measurement resources associated with CSI reporting are within the resources of one resource type, the channel measurement results or interference measurement results measured by the measurement resources can better reflect this resource type.

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

[0214] It should be noted that the network configures the time-frequency domain positions of the measurement resources associated with CSI reporting, and indicates that only some of the time-frequency domain positions of the measurement resources associated with CSI reporting need to be within the resources belonging to the first resource type or the second resource type. In this way, although only some of the time-frequency domain positions of the measurement resources associated with CSI reporting 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 these partial time-frequency domain positions associated with CSI reporting to perform channel measurement or interference measurement to separately reflect a resource type, avoiding resource waste caused by discarding the measurement resources at all the time-frequency domain positions associated with CSI reporting.

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

[0216] It should be noted that since the measurement resources associated with CSI reporting can include channel measurement resources and interference measurement resources, where the channel measurement resources are used for channel measurement and the interference measurement resources are used for interference measurement, in order to ensure that the channel measurement results and 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 both are the first resource type or both are the second resource type.

[0217]

Solution 3

[0218] Different from the above "Solution 2" where the measurement resources associated with CSI reporting are explicitly configured / indicated to belong to one of multiple resource types, in "Solution 3", in this embodiment, it is considered that the measurement resources configured for CSI measurement belong to multiple resource types, and the measurement resources associated with CSI reporting are implicitly configured / indicated to belong to one of multiple resource types.

[0219] In specific implementation, this embodiment can determine the resource type of the measurement resource associated with CSI reporting according to the resource type to which one of the measurement resources configured for CSI measurement belongs, so as to implement implicit configuration / implicit indication.

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

[0221] That is to say, the resource type to which this channel measurement resource belongs is used as the resource type of the measurement resource associated with CSI reporting, so that the resource type of the measurement resource associated with CSI reporting is the same as the resource type to which this channel measurement resource belongs, thus implementing 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. Hereinafter, this embodiment will be described by taking the multiple resource types including a first resource type and a second resource type, and the measurement resource associated with CSI reporting belonging to the first resource type or the second resource type as an example.

[0223] 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 at least one measurement resource for CSI measurement; correspondingly, the terminal device acquires the at least one measurement resource.

[0224] Among them, 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 the 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 a first measurement resource, the first measurement resource is a channel measurement resource among 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, through the resource type of the first measurement resource, implicit configuration / implicit indication is implemented that 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.

[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 the protocol, or is determined by the terminal device independently, or is pre-configured.

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

[0229] It should be noted that, in combination with the content in the above "CSI reference resource", the time-domain position of the measurement resource associated with the CSI report may be before the CSI reference resource corresponding to the CSI report, that is, the measurement resource before the time-domain position of 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, the resource type to which a channel measurement resource (i.e., the first measurement resource) that is the closest / adjacent in time-domain position to the CSI reference resource corresponding to the CSI report belongs among the measurement resources before the time-domain position of the CSI reference resource corresponding to the CSI report in the at least one measurement resource can be used as the resource type to which the measurement resource associated with the CSI report belongs. 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 with the smallest index / largest index among the at least one measurement resource.

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

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

[0233] It should be noted that, in combination with the content in the above "CSI reference resource", the time-domain position of the measurement resource associated with the CSI report may be before the CSI reference resource corresponding to the CSI report, that is, the measurement resource before the time-domain position of 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, the resource type to which a channel measurement resource (i.e., the first measurement resource) with the smallest index / largest index among the measurement resources before the time-domain position of the CSI reference resource corresponding to the CSI report in the at least one measurement resource belongs can be used as the resource type to which the measurement resource associated with the CSI report belongs, which is easy to implement.

[0234] Optionally, the resource type to which the channel measurement resource associated with the CSI report belongs is the same as the resource type to which the interference measurement resource associated with the CSI report belongs.

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

[0242] Combined with the content in the above "CSI reference resource", it can be known that n CSI_ref 's definition is related to the CSI reference resource corresponding to the CSI report being located in the effective downlink time slot. Since the effective downlink time slot needs to be redefined, n CSI_ref also needs to be redefined. For the convenience of description, hereinafter, n CSI_refThis is illustrated by taking the first parameter as an example. Among them, the first parameter may represent the time slot offset between the downlink time slot corresponding to the uplink time slot where the CSI report is located and the first effective downlink time slot or the second effective 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-persistent, 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 that makes the CSI reference resource corresponding to the CSI report located in the first effective 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-persistent, 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 that makes the CSI reference resource corresponding to the CSI report located in the second effective 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 aperiodic, and the DCI used to trigger the CSI report is in the same time slot as the CSI report, the first effective downlink time slot is the time slot where the DCI is located. the minimum value that makes the CSI reference resource corresponding to the CSI report located in the first effective 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 aperiodic, 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. the minimum value that makes the CSI reference resource corresponding to the CSI report located in the second effective downlink time slot.

[0247] Optionally, for the measurement resource associated with the CSI report belonging to the first resource type, if the CSI report is aperiodic, and the DCI used to trigger the CSI report is in the same time slot as the CSI report, the first effective downlink time slot is the time slot where the DCI is located.

[0248] Optionally, for the measurement resource associated with the CSI report belonging to the second resource type, if the CSI report is aperiodic, 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.

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

[0251]

Solution 5

[0252] In "Solution 5", in this embodiment, on the basis of the above "Solution 1", "Solution 2", "Solution 3" and "Solution 4", further consideration is given to the reporting of measurement results (such as channel measurement results and / or interference measurement results). Among them, the measurement results can be obtained according to the measurement resources associated with the CSI report, and the measurement results are carried by the CSI report.

[0253] Optionally, the measurement results include CSI information. Among them, 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 quantities may include at least one of the following: CSI-RS resource indicator (CRI), SSB resource indicator (SSBRI), rank indicator (RI), precoding matrix indicator (PMI), CQI, layer indicator (LI), capability index, time-domain channel properties (TDCP), etc.

[0255] In the process of reporting measurement results, the network device may configure one or more CSI reports for 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 to which the measurement resources associated with each CSI report belong 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, this embodiment will be described by taking the multiple resource types including a first resource type and a second resource type, and the CSI report including a first measurement result and / or a second measurement result.

[0258] Taking the interaction between the network device and the terminal device as an example for the measurement resources configured for CSI measurement, the network device sends at least one measurement resource for CSI measurement; correspondingly, the terminal device acquires 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 a first CSI report, the terminal device may measure a first measurement result according to the second measurement resource and send a CSI report to the network device, and the CSI report includes the first measurement result. In this way, after the network device acquires the first measurement result, it may perform accurate channel evaluation or interference evaluation on the first resource type according to 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 measure a second measurement result according to the third measurement resource and send a CSI report to the network device, and the CSI report includes the second measurement result. In this way, after the network device acquires the second measurement result, the network device may perform accurate channel evaluation or interference evaluation on the first resource type according to 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 may obtain a first measurement result according to the second measurement resource, and obtain a second measurement result according to the third measurement resource. At this time, the terminal device may send the CSI report in two times, where the CSI report in one time includes the first measurement result, and the CSI report in the other time includes the second measurement result. Additionally, to save signaling / resource overhead, the terminal device may send the CSI report once, 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 separately and individually represent a resource type, after the network device obtains the first measurement result and the second measurement result, the network device may perform accurate channel evaluation or interference evaluation on the first resource type according to the first measurement result, and perform accurate channel evaluation or interference evaluation on the second resource type according to the second measurement result.

[0262] 5. Example Illustration of a Communication Method

[0263] Combined with the above content, taking the interaction between a network device and a terminal device as an example, an example introduction of a communication method according to an embodiment of the present application is given below.

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

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

[0268] It can be seen that in this embodiment, the resource type of the measurement resource associated with the CSI report is indicated 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 according to 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 separately represent a resource type.
