[0001] Cross-reference to Related Applications

[0002] This application claims priority to Chinese Patent Application No. 202411096969.3, filed on August 9, 2024, entitled “Communication method and device, terminal device”, which is incorporated by reference herein in its entirety. TECHNICAL FIELD

[0003] The present application relates to the field of communication technology, and in particular to a communication method and device, and a terminal device. BACKGROUND

[0004] In a time division duplex (TDD) system, the transmission direction of the frequency band resources of a carrier at the same time needs to be the same, i.e., both are uplink or downlink, which also leads to time multiplexing of uplink and downlink of a carrier, and a relatively fixed uplink and downlink time slot ratio.

[0005] In order to avoid the deficiencies caused by the relatively fixed uplink and downlink time slot ratio as much as possible, and considering the implementation complexity of network devices, the 3rd Generation Partnership Project (3GPP) is discussing subband full duplex (SBFD), i.e., dividing non-overlapping uplink subbands and downlink subbands on the frequency band resources of the same carrier, so as to enable network devices to simultaneously support uplink transmission and downlink transmission, and improve spectrum utilization and flexibility.

[0006] When there are uplink subbands and downlink subbands on the frequency band of the same carrier, if a user performs uplink transmission on the uplink subband and another user performs downlink reception on the downlink subband, the signal in the uplink subband will possibly affect the signal in the downlink subband, i.e., the uplink transmission of the user will possibly interfere with the downlink reception of the other user, and this interference is called cross link interference (CLI). In particular, when the distance between the interfering user and the interfered user is very close, the CLI will be very serious. SUMMARY

In this way, since the CSI measurement reporting can be based on layer 1, the CLI measurement reporting based on the CSI measurement reporting framework can realize layer 1-based CLI measurement reporting, thereby facilitating to increase the timeliness of CLI measurement reporting and reduce the latency of CLI measurement reporting.

[0059] In some possible examples, the network device can include a device in an access network device and / or a core network (CN).

[0060] The access network device and the core network device are exemplarily described below.

[0061] [Network device]

[0062] In some possible examples, the access network device can be referred to as a radio access network (RAN) node. The RAN can be a network composed of multiple RAN nodes (for example, 5G-RAN nodes), implementing radio physical layer functions, resource scheduling and radio resource management, radio access control, and mobility management functions.

Among them, the "network element" can also be referred to as an entity, device, apparatus or module, etc., which is not specifically limited. In addition, in order to facilitate understanding and description, the description of "network element" is omitted in part of the description, for example, the network function exposure function (network exposure function, NEF) network element is simply referred to as NEF, in this case, the "NEF" should be understood as the NEF network element or the NEF entity, and the following description of the same or similar cases is omitted.

[0068] For example, the core network device can include a mobility management entity (mobility management entity, MME), a broadcast multicast service center (broadcast multicast service center, BMSC), etc., or can include a corresponding functional entity in a 5G system, such as a core network control plane (control plane, CP) or user plane (user plan, UP) network function, etc., and the core network control plane can also be understood as a core network control plane function (control plane function, CPF) entity.

In 5G networks and future other networks, the network elements described above can also be other names, which are not limited. For example, in 6G networks, some or all of the network elements described above can use the terms in 5G, or can be other names, etc. The same is described herein, and will not be described below.

[0072] In addition, the network elements in FIG. 2 are not necessarily present at the same time, and it can be determined according to requirements which network elements are needed. The connection relationship between the network elements in FIG. 2 is not uniquely determined, and can be adjusted according to requirements. It can be understood that the network elements or functions described above can be network elements in hardware devices, or can be software functions running on special hardware, or can be virtualized functions instantiated on a platform (for example, a cloud platform).

[0073] Of course, FIG. 2 is only an example of the network architecture of a communication system, and does not limit the network architecture of the communication system according to an embodiment of the present application.

[0074] The communication system has been described above, and the scenario of CLI measurement reporting based on a channel state information (CSI) measurement reporting framework according to an embodiment will be described below.

[0075]

CLI

[0076] In a TDD system, the transmission direction of the frequency band resources of one carrier at the same time needs to be the same, that is, both are uplink or downlink, which also leads to that the uplink and downlink of one carrier are time-multiplexed, and the uplink and downlink time slot ratio is relatively fixed. However, with the diversification of services, especially considering the service requirements of vertical industries, different services have different requirements for uplink and downlink transmission, so that the relatively fixed uplink and downlink time slot ratio cannot meet the requirements of different services.

[0077] In addition, in a TDD system, adjacent cells can be configured with different TDD uplink and downlink ratios, or different terminal devices in the same cell have different TDD uplink and downlink ratios. In this way, the uplink resources of a first terminal device in a cell and the downlink resources of a second terminal device in an adjacent cell have the same time-frequency domain position, or the uplink resources of a first terminal device in the same cell and the downlink resources of a second terminal device have the same time-frequency domain position, which leads to that the uplink transmission of the first terminal device can interfere with the downlink reception of the second terminal device, and this interference is called CLI between terminal devices. The CLI in the TDD system can be called full-band CLI.

[0078] In order to avoid the disadvantages caused by the relatively fixed uplink and downlink time slot ratio, flexibly use limited frequency spectrum resources to dynamically match business needs, improve resource utilization efficiency, and improve the uplink coverage, latency and other performance of data transmission, 3GPP introduces subband-based full duplex, also known as SBFD, which divides non-overlapping uplink and downlink subbands on the same carrier frequency band to enable network devices to support uplink and downlink transmission at the same time, thereby improving spectrum utilization and flexibility.

[0079] In the introduction of SBFD in TDD systems, the network device side is full duplex, that is, uplink and downlink transmission at the same time can be performed at different frequency domain locations, and to avoid interference between uplink and downlink, a certain guard band can be left between the frequency domain locations corresponding to different transmission directions (i.e., subbands); the terminal device side is half duplex, that is, uplink or downlink transmission can only be performed at the same time, and the two cannot be performed at the same time. In this way, in the network device side full duplex and terminal device side half duplex manner, the uplink and downlink transmission of the network device side at the same time can only be for different terminal devices.

[0080] In addition, in the introduction of SBFD in TDD systems, adjacent cells can divide different uplink and downlink subbands on the same carrier, or different terminal devices in the same cell have different uplink and downlink subbands on the same carrier.

[0081] For a certain terminal device, if the uplink subband of the terminal device and the downlink subband of another terminal device have different frequency domain locations and the same time domain location, the signal of the terminal device in the uplink subband will affect the signal of another terminal device in the downlink subband, that is, the uplink transmission of the terminal device will interfere with the downlink reception of another terminal device, and this interference is called inter-subband CLI.

[0082] For a certain terminal device, if the uplink subband of the terminal device and the downlink subband of another terminal device have the same time-frequency domain location, the uplink transmission of the terminal device will interfere with the downlink reception of another terminal device, and this interference is called intra-subband CLI.

[0083]

CLI measurement reporting

[0084] In CLI measurement reporting, the CLI-related configuration includes CLI resource configuration. For example, the measurement object CLI (MeasObjectCLI) information in the high-level parameter contains CLI resource configuration (CLI-ResourceConfig) information.

[0085] Optionally, CLI-ResourceConfig information can be used to configure at least one CLI resource list, each of which includes at least one CLI resource. Wherein, the CLI resource is used for CLI measurement.

[0086] Optionally, the CLI-ResourceConfig information can include sounding reference signal-ResourceListConfig (SRS-ResourceListConfig) information and received signal strength indicator-ResourceListConfig (RSSI-ResourceListConfig) information.

[0087] Optionally, the SRS-ResourceListConfig information can be used to configure an SRS resource list, and the SRS resource list includes at least one SRS resource. Wherein, the SRS resource is used for SRS-RSRP measurement.

[0088] Optionally, the SRS-ResourceListConfig information can include SRS-ResourceConfigCLI information, which can be used to configure an SRS resource.

[0089] Optionally, the RSSI-ResourceListConfig information can be used to configure an RSSI list, and the RSSI resource list includes at least one RSSI resource. Wherein, the RSSI resource is used for CLI-RSSI measurement.

[0090] Optionally, the RSSI-ResourceListConfig information can include RSSI-ResourceConfigCLI information, which can be used to configure an RSSI resource.

[0091] For the terminal device, the terminal device can perform CLI measurement according to the CLI resource to obtain CLI information. In the CLI reporting process, the terminal device can feed back or report the CLI information to the network device through the CLI report. The CLI information can be the CLI measurement result information obtained by performing the CLI measurement according to the CLI resource. For example, for SRS-RSRP measurement, the CLI information includes SRS-RSRP; for CLI-RSSI measurement, the CLI information includes CLI-RSSI.

[0092] In a communication system, different interfaces can define respective protocol stacks, and the protocols can be layered, such as layer 1 (L1), layer 2 (L2), and layer 3 (L3). The layer 1 can refer to a physical layer protocol; the layer 2 can refer to a data link layer, which can include a PDCP layer, a radio link control (RLC) layer, and / or a MAC layer; and the layer 3 can refer to a network layer, which can include an RRC layer.

[0093] Currently, the CLI measurement reporting framework is based on layer 3 CLI measurement reporting, and the CLI information obtained by the CLI measurement needs to be filtered at layer 3 before being reported, thereby reducing the timeliness of the CLI measurement reporting and increasing the latency of the CLI measurement reporting. Meanwhile, the CLI reporting is periodic or event-triggered.

[0094] Based on this, the present embodiment introduces CLI measurement reporting based on a CSI measurement reporting framework. That is, the CLI measurement reporting is based on the CSI measurement reporting framework. This is because, since the CSI measurement reporting can be based on layer 1, the CLI measurement reporting based on the CSI measurement reporting framework can implement layer 1-based CLI measurement reporting, thereby facilitating the increase of the timeliness of the CLI measurement reporting and the reduction of the latency of the CLI measurement reporting.

[0095] The CSI measurement reporting framework and the CLI measurement reporting based on the CSI measurement reporting framework are described below.

[0096]

CSI measurement reporting framework

[0097] In the CSI measurement reporting framework, the CSI-related configuration includes CSI resource configuration and / or CSI report configuration. For example, the CSI measurement configuration (CSI-MeasConfig) information in the high-layer parameter contains the following two high-layer parameters: CSI resource configuration (CSI-ResourceConfig) information and CSI report configuration (CSI-ReportConfig) information.

[0098] Optionally, the CSI-ReportConfig information can comprise CSI resource configuration identification (CSI-ResourceConfigId) information. The CSI-ResourceConfigId information can indicate the CSI-ResourceConfig information. In this way, the CSI-ReportConfig information is associated with or corresponds to the CSI-ResourceConfig information through the CSI-ResourceConfigId information.

[0099] Optionally, the CSI-ReportConfig information can be used for configuration of CSI reporting, i.e., configuration of CSI reporting.

[0100] Optionally, the CSI-ResourceConfig information can comprise at least one of non-zero power CSI-RS resource set list (NZP-CSI-RS-ResourceSetList) information, CSI interference measurement resource set list (CSI-Interference-Measurement-ResourceSetList, CSI-IM-ResourceSetList) information, and CSI synchronization signal block resource set list (CSI-SSB-ResourceSetList) information.

[0101] Optionally, the NZP-CSI-RS-ResourceSetList information can be used for configuration of a NZP-CSI-RS resource set list, and the NZP-CSI-RS resource set list comprises at least one NZP-CSI-RS resource set, and each NZP-CSI-RS resource set comprises at least one NZP-CSI-RS resource. The NZP-CSI-RS resource can be used for channel measurement and / or interference measurement.

[0102] Optionally, the NZP-CSI-RS-ResourceSetList information can comprise NZP-CSI-RS-ResourceSet information, and the NZP-CSI-RS-ResourceSet information can be used for configuration of a NZP-CSI-RS resource set, and the NZP-CSI-RS resource set comprises at least one NZP-CSI-RS resource.

[0103] Optionally, the CSI-IM-ResourceSetList information can be used to configure a CSI-IM resource set list, the CSI-IM resource set list including at least one CSI-IM resource set, each CSI-IM resource set including at least one CSI-IM resource. The CSI-IM resource can be used for interference measurement.

[0104] Optionally, the CSI-IM-ResourceSetList information can include CSI-IM-ResourceSet information. The CSI-IM-ResourceSet information can be used to configure a CSI-IM resource set, the CSI-IM resource set including at least one CSI-IM resource.

[0105] Optionally, the CSI-SSB-ResourceSetList information can be used to configure a CSI-SSB resource set list, the CSI-SSB resource set list including at least one CSI-SSB resource set, each CSI-SSB resource set including at least one CSI-SSB resource. The CSI-SSB resource can be used for channel measurement.

[0106] Optionally, the CSI-SSB-ResourceSetList information can include CSI-SSB-ResourceSet information. The CSI-SSB-ResourceSet information can be used to configure a CSI-SSB resource set, the CSI-SSB resource set including at least one CSI-SSB resource.

[0107] For the terminal device, the terminal device can perform CSI measurement, CSI calculation, and CSI reporting, etc. according to the CSI resource configuration information and the CSI reporting configuration information. The CSI calculation can include at least one of the following: channel quality indicator (CQI) calculation, precoding matrix indicator (PMI) calculation, or rank indicator (RI) calculation, etc.

[0108] For example, in the CSI measurement and CSI calculation process, the terminal device can perform CSI measurement (such as channel measurement and / or interference measurement) and / or CSI calculation according to the CSI resource (such as NZP-CSI-RS resource number, etc.) to obtain CSI information. In the CSI reporting process, the terminal device can feed back or report the CSI information to the network device through the CSI report, so that the network device can perform link adaptation according to the CSI information.

[0109] The CSI information can be related information obtained according to the CSI measurement and / or CSI calculation, or can be related information used to evaluate and describe the channel state, or can be related information determined according to the channel matrix H, etc.

[0110] For example, the CSI information includes at least one of the following: CSI reference signal resource indicator (CRI), synchronization signal block resource indicator (SSBRI), RI, PMI, CQI, layer indicator (LI), time-domain channel properties (TDCP), layer 1 reference signal received power (L1-RSRP), layer 1 signal-to-noise and interference ratio (L1-SINR), angle of arival (AOA), angle of arrival spread (AAS), angle of departure (AOD), angle of departure spread (ADS), or spatial correlation, etc.

[0111] It is worth noting that the content included in the CSI information of the present embodiment can not be limited to the above-mentioned content, and can be adjusted according to the actual situation in actual application. That is, any related information that can be used to describe the channel state can be the CSI information of the present embodiment, and no specific limitation is made thereto.

CLI measurement reporting based on the CSI measurement reporting framework

[0113] In the CLI measurement reporting based on the CSI measurement reporting framework, the present embodiment can consider the following two cases:

[0114] Case 1:

[0115] In "Case 1", the embodiment introduces CSI-ReportConfig information to associate CLI-ResourceConfig information.

[0116] For example, in FIG. 3, the CSI-ReportConfig information is associated with the CSI-ResourceConfig information and the CLI-ResourceConfig information, the CLI-ResourceConfig information contains the SRS-ResourceListConfig information and the RSSI-ResourceListConfig information, the SRS-ResourceListConfig information contains the SRS-ResourceConfigCLI information, and the RSSI-ResourceListConfig information contains the RSSI-ResourceConfigCLI information.

[0117] It should be noted that in combination with the above-mentioned "CLI measurement reporting", the CLI-ResourceConfig information is used to configure at least one CLI resource list, each CLI resource list includes at least one CLI resource, and the CLI resource can be an SRS resource or an RSSI resource.

[0118] Therefore, the CSI-ReportConfig information associated with the CLI-ResourceConfig information can be understood as the CSI-ReportConfig information associated with at least one CLI resource list.

[0119] In some possible examples, the CSI-ReportConfig information contains CLI resource configuration identification (CLI-ResourceConfigId) information. The CLI resource configuration identification information can indicate the CSI-ResourceConfig information. In this way, the CSI-ReportConfig information is associated with the CLI-ResourceConfig information through the CLI resource configuration identification information.

[0120] Case 2:

[0121] In "Case 2", the embodiment introduces the CSI-ResourceConfig information to associate the SRS-ResourceListConfig information and / or the RSSI-ResourceListConfig information.

[0122] For example, in FIG. 4, the CSI-ReportConfig information is associated with the CSI-ResourceConfig information, the CSI-ResourceConfig information is associated with the SRS-ResourceListConfig information and the RSSI-ResourceListConfig information, the SRS-ResourceListConfig information contains the SRS-ResourceConfigCLI information, and the RSSI-ResourceListConfig information contains the RSSI-ResourceConfigCLI information.

[0123] It should be noted that in combination with the above-mentioned content in the "CLI measurement reporting", the SRS-ResourceListConfig information is used to configure the SRS resource list, and the RSSI-ResourceListConfig information is used to configure the RSSI resource list. Among them, the SRS resource list and the RSSI resource list can be referred to as the CLI resource list.

[0124] Therefore, the CSI-ResourceConfig information is associated with the SRS-ResourceListConfig information and / or the RSSI-ResourceListConfig information, which can be understood as that the CSI-ResourceConfig information is associated with the CLI resource list.

[0125] In some possible examples, the CSI-ResourceConfig information contains SRS resource configuration identifier (SRS-ResourceConfigId) information. Among them, the SRS-ResourceConfigId information can indicate the SRS-ResourceListConfig information. In this way, through the SRS-ResourceListConfig information, the CSI-ResourceConfig information is associated with the SRS-ResourceListConfig information.

[0126] In some possible examples, the CSI-ResourceConfig information contains RSSI resource configuration identifier (RSSI-ResourceConfigId) information. Among them, the RSSI-ResourceConfigId information can indicate the RSSI-ResourceListConfig information. In this way, through the RSSI-ResourceListConfig information, the CSI-ResourceConfig information is associated with the RSSI-ResourceListConfig information.

[0127] In some possible examples, the CSI-ResourceConfig information contains SRS-ResourceConfigId information and RSSI-ResourceConfigId information. In this way, the CSI-ResourceConfig information associates the SRS-ResourceListConfig information and the RSSI-ResourceListConfig information through the SRS-ResourceConfigId information and the RSSI-ResourceConfigId information.

[0128] Case 3:

[0129] In the "Case 3", the embodiment introduces the CSI-ReportConfig information to associate the CLI resource configuration information.

[0130] For the CSI-ReportConfig information to associate the CLI resource configuration information, one possible implementation is that the CSI-ReportConfig information contains CLI-ResourceConfigId information, and the CLI-ResourceConfigId information can indicate the CLI resource configuration information. In this way, the CSI-ReportConfig information associates the CLI resource configuration information through the CLI-ResourceConfigId information.

[0131] For the CLI resource configuration information, the embodiment has the following definitions:

[0132] Definition a:

[0133] In the "Definition a", the CLI resource configuration information can be used to configure a CLI resource set list. In this way, the CSI-ReportConfig information to associate the CLI resource configuration information can be understood as the CSI-ReportConfig information to associate the CLI resource set list.

[0134] The CLI resource set list includes at least one CLI resource set, and each CLI resource set includes at least one CLI resource. The CLI resource can be an SRS resource or an RSSI resource.

[0135] For example, in FIG. 5, the CSI-ReportConfig information is associated with CLI resource configuration information. The CLI resource configuration information includes SRS-ResourceSetListConfig information and RSSI-ResourceSetListConfig information. The SRS-ResourceSetListConfig information is used to configure a SRS resource set list, and the SRS resource set list includes at least one SRS resource set. The RSSI-ResourceSetListConfig information is used to configure a RSSI resource set list, and the RSSI resource set list includes at least one RSSI resource set.

[0140] The CLI resource set includes at least one CLI resource, and the CLI resource can be a SRS resource or a RSSI resource.

[0141] For example, in FIG. 6, the CSI-ReportConfig information is associated with CLI resource configuration information. The CLI resource configuration information includes SRS-ResourceSet information and RSSI-ResourceSet information. The SRS-ResourceSet information includes SRS-Resource information. The RSSI-ResourceSet information includes RSSI-Resource information.

[0142] Definition c:

[0143] In "Definition c", the CLI resource configuration information can be used to configure at least one CLI resource list. At this time, the CLI resource configuration information is equivalent to the CLI-ResourceConfig information, which is similar to the above-mentioned "Case 1", and will not be described again.

[0144] Definition d:

[0145] In "Definition d", the CLI resource configuration information can be used to configure the CLI resource list. In this way, the CSI-ReportConfig information is associated with the CLI resource configuration information, and it can be understood that the CSI-ReportConfig information is associated with the CLI resource list.

[0146] For example, in FIG. 7, the CSI-ReportConfig information is associated with the SRS-ResourceListConfig information and the RSSI-ResourceListConfig information. The SRS-ResourceListConfig information contains the SRS-ResourceConfigCLI information, and the RSSI-ResourceListConfig information contains the RSSI-ResourceConfigCLI information.

[0147] Definition e:

[0148] In "Definition e", the CLI resource configuration information can be used to configure the CLI resource. In this way, the CSI-ReportConfig information is associated with the CLI resource configuration information, and it can be understood that the CSI-ReportConfig information is associated with the CLI resource.

[0149] For example, the CSI-ReportConfig information is associated with the SRS-ResourceConfigCLI information and the RSSI-ResourceConfigCLI information.

[0150] Case 4:

[0151] In "Case 4", the present embodiment introduces the CSI-ResourceConfig information associated with the CLI resource configuration information.

[0152] For CSI-ResourceConfig information associating CLI resource configuration information, one possible implementation is that: the CSI-ResourceConfig information contains CLI resource configuration identification information, which can indicate the CLI resource configuration information. In this way, the CSI-ResourceConfig information associates the CLI resource configuration information through the CLI resource configuration identification information.

[0153] For the CLI resource configuration information, the embodiment has the following definitions:

[0154] Definition 1:

[0155] In "Definition 1", the CLI resource configuration information can be used to configure a CLI resource set. In this way, the CSI-ResourceConfig information associating the CLI resource configuration information can be understood as the CSI-ResourceConfig information associating the CLI resource set.

[0156] For example, in FIG. 8, the CSI-ResourceConfig information associates the CLI resource configuration information. The CLI resource configuration information contains SRS-ResourceSetConfig information and RSSI-ResourceSetConfig information. The SRS-ResourceSetConfig information contains SRS-Resource information. The RSSI-ResourceSetConfig information contains RSSI-Resource information.

[0157] Definition 2:

[0158] In "Definition 2", the CLI resource configuration information can be used to configure at least one CLI resource list. At this time, the CLI resource configuration information is equivalent to the CLI-ResourceConfig information, which is similar to the above "Case 2", and will not be described again.

[0159] Definition 3:

[0160] In "Definition 3", the CLI resource configuration information can be used to configure a CLI resource list. In this way, the CSI-ResourceConfig information associating the CLI resource configuration information can be understood as the CSI-ResourceConfig information associating the CLI resource list.

[0161] For example, in FIG. 9, the CSI-ResourceConfig information associates the SRS-ResourceListConfig information and the RSSI-ResourceListConfig information. The SRS-ResourceListConfig information contains the SRS-ResourceConfigCLI information, and the RSSI-ResourceListConfig information contains the RSSI-ResourceConfigCLI information.

[0162] Definition 4:

[0163] In "Definition 4", the CLI resource configuration information can be used to configure the CLI resource. In this way, the CSI-ResourceConfig information associates the CLI resource configuration information, which can be understood as that the CSI-ResourceConfig information associates the CLI resource.

[0164] For example, the CSI-ResourceConfig information associates the SRS-ResourceConfigCLI information and the RSSI-ResourceConfigCLI information.

[0165] For the process of CLI measurement reporting based on the CSI measurement reporting framework, the following embodiments take the first CLI resource as an example for illustration. The first CLI resource includes at least one CLI resource.

[0166] It should be noted that for the above "case 1", the CLI-ResourceConfig information is used to configure the first CLI resource, that is, the first CLI resource is at least one CLI resource list. Therefore, the first CLI resource includes at least one CLI resource. At the same time, the first CLI resource associates the CSI-ReportConfig information.

[0167] For the above "case 2", the SRS-ResourceListConfig information or the RSSI-ResourceListConfig information is used to configure the first CLI resource, that is, the first CLI resource is a CLI resource list. Therefore, the first CLI resource includes at least one CLI resource. At the same time, the first CLI resource associates the CSI-ResourceConfig information.

[0168] For the above "Case 3", the CLI resource configuration information is used to configure the first CLI resource. Wherein, in "Definition a", the first CLI resource is a CLI resource set list; in "Definition b", the first CLI resource is a CLI resource set; in "Definition c", the first CLI resource is at least one CLI resource list; in "Definition d", the first CLI resource is a CLI resource list; in "Definition e", the first CLI resource is one CLI resource. Therefore, the first CLI resource includes at least one CLI resource. At the same time, the first CLI resource is associated with the CSI-ReportConfig information.

[0169] For the above "Case 4", the CLI resource configuration information is used to configure the first CLI resource. Wherein, in "Definition 1", the first CLI resource is a CLI resource set; in "Definition 2", the first CLI resource is at least one CLI resource list; in "Definition 3", the first CLI resource is a CLI resource list; in "Definition 4", the first CLI resource is one CLI resource. Therefore, the first CLI resource includes at least one CLI resource. At the same time, the first CLI resource is associated with the CSI-ResourceConfig information.

[0170] The following is an example of the process of CLI measurement reporting based on the CSI measurement reporting framework, taking the interaction between the network device and the terminal device as an example. Wherein, the network device can be a communication device, a chip or a chip component, etc., and the terminal device can be a communication state, a chip or a chip component, etc. As shown in FIG. 10, FIG. 10 is a flow diagram of a communication method according to an embodiment of the present application, which includes the following steps:

[0171] S1010. The terminal device determines the first CLI resource, and the first CLI resource is associated with the CSI-ReportConfig information or the CSI-ResourceConfig information.

[0172] S1020. The terminal device performs CLI measurement according to the first CLI resource to obtain CLI information.

[0173] S1030. The terminal device sends the first CSI report, and the first CSI report carries the CLI information.

[0174] Correspondingly, the network device receives the first CSI report.

[0175] It can be seen that, since the first CLI resource is associated with the CSI-ReportConfig information or the CSI-ResourceConfig information, and the first CLI resource is used for CLI measurement, the embodiment can realize CLI measurement based on the CSI measurement reporting framework. In addition, since the first CSI report carries CLI information, the terminal device can feed back or report the CLI information to the network device through the first CSI report, so as to realize CLI reporting based on the CSI measurement reporting framework. In this way, since the CSI measurement reporting can be based on layer 1, the CLI measurement reporting based on the CSI measurement reporting framework can realize layer 1-based CLI measurement reporting, thereby facilitating to increase the timeliness of CLI measurement reporting and reduce the latency of CLI measurement reporting.

[0176] The determination of the first CLI resource in S1010 is described below.

[0177] For the determination of the first CLI resource in S1010, one possible implementation is to obtain at least one of a carrier, a bandwidth part (BWP) or a subcarrier spacing (SCS); and determine the frequency domain position of the first CLI resource according to at least one of the carrier, the BWP or the SCS.

[0178] In this way, the terminal device can determine the frequency domain position of the first CLI resource according to at least one of the carrier, the BWP or the SCS, and realize network configuration of the first CLI resource.

[0179] For the obtaining of at least one of the carrier, the BWP or the SCS, one possible implementation is that the network device sends frequency domain configuration information, and the frequency domain configuration information is used to configure at least one of the carrier, the BWP or the SCS; and correspondingly, the terminal device receives the configuration information.

[0180] In this way, at least one of the carrier, the BWP or the SCS is configured by the network through the frequency domain configuration information.

[0181] It should be noted that the frequency domain configuration information can be carried by high layer signaling (such as RRC signaling). For example, the frequency domain configuration information can be in at least one of the CSI-ReportConfig information, the CSI-ResourceConfig information, the CLI-ResourceConfig information or the CLI resource configuration information. The following is described in different ways.

[0182]

Way 1

[0183] In the "Manner 1", the frequency domain configuration information is in the CLI resource configuration information. For the CLI resource configuration information being associated with the CSI-ReportConfig information or the CSI-ResourceConfig information, the CLI resource configuration information contains at least one of the first carrier, the first BWP, or the first SCS. Wherein, the CLI resources configured by the CLI resource configuration information can all be determined according to at least one of the first carrier, the first BWP, or the first SCS.

[0184] It should be noted that the CLI resource configuration can be used to configure a CLI resource set list, a CLI resource set, at least one CLI resource list, or a CLI resource. Therefore, the first carrier, the first BWP, and the first SCS need to be explained in different cases.

[0185] For the case that the CLI resource configuration information is used to configure a CLI resource set list, the first carrier can determine the CLI resources in the CLI resource set list, that is, each CLI resource in the CLI resource set list can be determined according to the same first carrier; or the first BWP can determine the CLI resources in the CLI resource set list, that is, each CLI resource in the CLI resource set list can be determined according to the same first BWP; or the first SCS can determine the CLI resources in the CLI resource set list, that is, each CLI resource in the CLI resource set list can be determined according to the same first SCS.

[0186] For the case that the CLI resource configuration information is used to configure a CLI resource set, the first carrier can determine the CLI resources in the CLI resource set, that is, each CLI resource in the CLI resource set can be determined according to the same first carrier; or the first BWP can determine the CLI resources in the CLI resource set, that is, each CLI resource in the CLI resource set can be determined according to the same first BWP; or the first SCS can determine the CLI resources in the CLI resource set, that is, each CLI resource in the CLI resource set can be determined according to the same first SCS.

[0187] For the case that the CLI resource configuration information is used to configure at least one CLI resource list, the first carrier can determine the CLI resource in the at least one CLI resource list, that is, each CLI resource in the at least one CLI resource list can be determined according to the same first carrier; or the first BWP can determine the CLI resource in the at least one CLI resource list, that is, each CLI resource in the at least one CLI resource list can be determined according to the same first BWP; or the first SCS can determine the CLI resource in the at least one CLI resource list, that is, each CLI resource in the at least one CLI resource list can be determined according to the same first SCS.

[0188] For the case that the CLI resource configuration information is used to configure at least one CLI resource list, the first carrier can determine the CLI resource in the at least one CLI resource list, that is, each CLI resource in the at least one CLI resource list can be determined according to the same first carrier; or the first BWP can determine the CLI resource in the at least one CLI resource list, that is, each CLI resource in the at least one CLI resource list can be determined according to the same first BWP; or the first SCS can determine the CLI resource in the at least one CLI resource list, that is, each CLI resource in the at least one CLI resource list can be determined according to the same first SCS.

[0189] For example, taking the CLI resource configuration information as SRS-ResourceConfigCLI information, the first carrier is the reference carrier in the SRS-ResourceConfigCLI information, the first BWP is the reference BWP in the SRS-ResourceConfigCLI information, and the first SCS is the reference SCS in the SRS-ResourceConfigCLI information. The SRS resource configured by the SRS-ResourceConfigCLI information is determined according to at least one of the reference carrier, the reference BWP, or the reference SCS. For example, the reference BWP can determine the frequency reference point of the SRS resource, the frequency reference point of the SRS resource is the subcarrier 0 of the common resource block 0 (CRB0) of the reference serving cell, the reference carrier can determine the reference serving cell to which the reference BWP belongs, and the reference SCS can determine the SCS of the SRS resource. That is, the frequency domain position of the SRS resource is determined according to the reference BWP and the reference SCS on the reference carrier.

[0190] For example, taking the CLI resource configuration information as the RSSI-ResourceConfigCLI information, the first carrier is the reference carrier in the RSSI-ResourceConfigCLI information, the first BWP is the reference BWP in the RSSI-ResourceConfigCLI information, and the first SCS is the reference SCS in the RSSI-ResourceConfigCLI information. The RSSI resource configured by the RSSI-ResourceConfigCLI information is determined according to at least one of the reference carrier, the reference BWP, or the reference SCS. For example, the reference BWP can determine the frequency reference point of the RSSI resource, the frequency reference point of the RSSI resource is subcarrier 0 of CRB 0 of the reference serving cell, the reference carrier can determine the reference serving cell to which the reference BWP belongs, and the reference SCS can determine the SCS of the SRS resource. The RSSI resource is determined according to the physical resource block (PRB) index and the PRB number of the frequency reference point of the RSSI resource, and the PRB is determined according to the reference SCS. That is, the frequency domain starting position of the RSSI resource is determined according to the reference carrier, and the PRB occupied by the RSSI resource is determined according to the reference SCS.

[0191] Based on this, for determining the frequency domain position of the first CLI resource according to at least one of the carrier, the BWP, or the SCS, one possible implementation is to determine the frequency domain position of the first CLI resource according to at least one of the first carrier, the first BWP, or the first SCS in the CLI resource configuration information. In this way, the first CLI resource is determined through the CLI resource configuration information.

[0192] That is, the carrier here is the first carrier in the CLI resource configuration information, the BWP here is the first BWP in the CLI resource configuration information, and the SCS here is the first SCS in the CLI resource configuration information.

[0193] In some possible examples, since the first carrier, the first BWP, and the first SCS can be different from the measurement carrier, the activated BWP, and the SCS on the activated BWP, the first CLI resource can be out of the range of the activated BWP. That is, part of the CLI resources in the first CLI resource are within the activated BWP, and another part of the CLI resources are outside the activated BWP. At this time, the CLI resources within the activated BWP are valid CLI resources, and the CLI resources outside the activated BWP are invalid CLI resources. The valid CLI resources can be used for CLI measurement, and the invalid CLI resources cannot be used for CLI measurement.

[0194] Thus, for the CLI measurement according to the first CLI resource to obtain the CLI information in S1020, one possible implementation is that: the CLI measurement is performed according to the CLI resource in the first CLI resource which is within the active BWP to obtain the CLI information. Thus, the CLI measurement is implemented through the CLI resource in the first CLI resource which is within the active BWP.

[0195]

Manner 2

[0196] In the “Manner 2”, the frequency domain configuration information is in the CSI-ReportConfig information and / or the CSI-ResourceConfig information. Wherein, the second carrier is contained in the CSI-ReportConfig information, and the CSI resources configured by the CSI-ResourceConfig information associated with the CSI-ReportConfig information are determined according to the second carrier. In addition, the second BWP is contained in the CSI-ResourceConfig information, and the CSI resources configured by the CSI-ResourceConfig information are determined according to the second BWP.

[0197] Thus, for the above-mentioned “Case 1”, since the CLI resource configuration information is associated with the CSI-ReportConfig information, and the second carrier is contained in the CSI-ReportConfig information, the first CLI resource configured by the CLI resource configuration information can be determined according to the second carrier.

[0198] For the above-mentioned “Case 2”, since the SRS-ResourceListConfig information and / or the RSSI-ResourceListConfig information is associated with the CSI-ResourceConfig information, and the second BWP is contained in the CSI-ResourceConfig information, the first CLI resource configured by the SRS-ResourceListConfig information or the RSSI-ResourceListConfig information can be determined according to the second BWP and / or the SCS of the second BWP. In addition, since the CSI-ReportConfig information is also associated with the CSI-ResourceConfig information, and the second carrier is contained in the CSI-ReportConfig information, the first CLI resource configured by the SRS-ResourceListConfig information or the RSSI-ResourceListConfig information can also be determined according to the second carrier.

[0199] Based on this, for determining the frequency domain location of the first CLI resource according to at least one of the carrier, the BWP, or the SCS, one possible implementation is: determining the frequency domain location of the first CLI resource according to at least one of the second carrier in the CSI-ReportConfig information, the second BWP in the CSI-ResourceConfig information, or the SCS of the second BWP. In this way, the determination of the first CLI resource is realized through the CSI-ReportConfig information and / or the CSI-ResourceConfig information.

[0200] That is, the carrier here is the second carrier in the CSI-ReportConfig information, the BWP here is the second BWP in the CSI-ResourceConfig information, and the SCS here is the SCS of the second BWP.

[0201] In some possible examples, if the first CLI resource is determined according to the second BWP, and the second BWP is the active BWP, all the CLI resources in the first CLI resource can be within the active BWP. At this time, all the CLI resources in the second CLI resource are valid CLI resources. The valid CLI resources can be used for CLI measurement.

[0202] In some possible examples, since the second carrier can be different from the measurement carrier, the first CLI resource determined according to the second carrier can be out of the range of the active BWP. That is, part of the CLI resources in the first CLI resource are within the active BWP, and another part of the CLI resources are out of the active BWP. At this time, the CLI resources within the active BWP are valid CLI resources, and the CLI resources out of the active BWP are invalid CLI resources. The valid CLI resources can be used for CLI measurement, and the invalid CLI resources cannot be used for CLI measurement.

[0203] In this way, for the CLI measurement according to the first CLI resource in S1020 to obtain the CLI information, one possible implementation is: performing CLI measurement according to the CLI resources in the first CLI resource that are within the active BWP to obtain the CLI information. In this way, the CLI measurement is realized through the CLI resources in the first CLI resource that are within the active BWP.

[0204]

Way 3

[0205] In the "mode 3", the embodiment combines the "mode 1" and the "mode 2" above, and introduces the concept of priority of the carrier, priority of the BWP, and priority of the SCS. Among them, the frequency domain configuration information includes at least one of the CSI-ReportConfig information, the CSI-ResourceConfig information, or the CLI resource configuration information.

[0206] For the CLI resource configuration information containing the first carrier and the CSI-ReportConfig information containing the second carrier, the embodiment considers that the first carrier and the second carrier each has a priority. Among them, the priority of the first carrier and the priority of the second carrier are configured by the network, indicated by the network, predefined, preconfigured, or specified by the standard protocol. In this way, the embodiment can determine the first CLI resource according to the one with higher priority in the first carrier and the second carrier.

[0207] For the CLI resource configuration information containing the first BWP and the CSI-ResourceConfig information containing the second BWP, the embodiment considers that the first BWP and the second BWP each has a priority. Among them, the priority of the first BWP and the priority of the second BWP are configured by the network, indicated by the network, predefined, preconfigured, or specified by the standard protocol. In this way, the embodiment can determine the first CLI resource according to the one with higher priority in the first BWP and the second BWP.

[0208] For the CLI resource configuration information containing the first SCS and the SCS of the second BWP, the embodiment considers that the first SCS and the SCS of the second BWP each has a priority. Among them, the priority of the first SCS and the priority of the SCS of the second BWP are configured by the network, indicated by the network, predefined, preconfigured, or specified by the standard protocol. In this way, the embodiment can determine the first CLI resource according to the one with higher priority in the first SCS and the SCS of the second BWP.

[0209] Based on this, for determining the first CLI resource according to at least one of the carrier, the BWP, or the SCS, one possible implementation is to determine the frequency domain position of the first CLI resource according to at least one of the one with higher priority in the first carrier and the second carrier, the one with higher priority in the first BWP and the second BWP, or the one with higher priority in the first SCS and the SCS of the second BWP. In this way, the CSI-ReportConfig information and / or the CSI-ResourceConfig information are used to determine the first CLI resource.

[0210] That is, the carrier here is the higher one of the first carrier and the second carrier, the BWP here is the higher one of the first BWP and the second BWP, and the SCS here is the higher one of the first SCS and the SCS of the second BWP.

[0211] In some possible examples, all of the CLI resources in the first CLI resources are within the active BWP; or, part of the CLI resources in the first CLI resources are within the active BWP, and another part of the CLI resources are outside the active BWP. At this time, the CLI resources within the active BWP are valid CLI resources, and the CLI resources outside the active BWP are invalid CLI resources. Wherein, the valid CLI resources can be used for CLI measurement, and the invalid CLI resources cannot be used for CLI measurement.

[0212] In this way, for the CLI measurement according to the first CLI resources to obtain the CLI information in S1020, one possible implementation is that the CLI measurement is performed according to the CLI resources in the first CLI resources that are within the active BWP to obtain the CLI information. In this way, the CLI measurement is implemented through the CLI resources in the first CLI resources that are within the active BWP.

[0213] The time domain period and / or time domain offset of the first CLI resources are exemplified as follows.

[0214] For the determination of the first CLI resources in S1010, one possible implementation is that the time domain period and / or time domain offset of the first CLI resources are determined.

[0215] In this way, the time domain position of the first CLI resources can be determined through the time domain period and / or time domain offset of the first CLI resources. For the determination of the time domain period and / or time domain offset of the first CLI resources, one possible implementation is that the network device sends time domain configuration information, and the time domain configuration information is used to configure the time domain period and / or time domain offset of the first CLI resources.

[0216] It should be noted that the time domain configuration information can be carried by high layer signaling (such as RRC signaling). For example, the frequency domain configuration information can be in at least one of the CSI-ReportConfig information, the CSI-ResourceConfig information, the CLI-ResourceConfig information, or the CLI resource configuration information.

[0217] In some possible examples, the minimum value of the time domain period of the CLI resources in the first CLI resources is less than or equal to 10 time units; and / or, the maximum value of the time domain period of the CLI resources in the first CLI resources is greater than or equal to 640 time units.

[0218] In this way, the embodiment can determine the time domain period range of the first CLI resource through the minimum value of the time domain period and / or the maximum value of the time domain period of the first CLI resource.

[0219] It should be noted that the network device can configure one value in the time domain period range of the first CLI resource to the terminal device through a high-level parameter (such as CLI resource configuration information, CLI-ResourceConfig information, or CSI-ResourceConfig information) in high-level signaling. At this time, the time period of the first CLI resource is the value.

[0220] For the minimum value of the time domain period of the first CLI resource being less than 10 time units, one possible way is that the minimum value of the time domain period of the first CLI resource is 1 time unit or 4 time units. For the minimum value of the time domain period of the first CLI resource being greater than 640 time units, one possible way is that the maximum value of the time domain period of the first CLI resource is 2560 time units.

[0221] In addition, the time unit can represent a basic unit on the time domain resource. For example, the time unit can be a time slot, a symbol, or a mini-slot.

[0222] For example, taking a time unit of a time slot as an example, the range of the time domain period of the first CLI resource of the embodiment can be 10 time slots to 640 time slots. At this time, the minimum value of the time domain period of the first CLI resource is 10 time slots, and the maximum value of the time domain period of the first CLI resource is 640 time slots.

[0223] For example, taking a time unit of a time slot as an example, the range of the time domain period of the first CLI resource of the embodiment can be 4 time slots to 640 time slots. At this time, the minimum value of the time domain period of the first CLI resource is 4 time slots, and the maximum value of the time domain period of the first CLI resource is 640 time slots.

[0224] For example, taking a time unit of a time slot as an example, the range of the time domain period of the first CLI resource of the embodiment can be 1 time slot to 2560 time slots. At this time, the minimum value of the time domain period of the first CLI resource is 1 time slot, and the maximum value of the time domain period of the first CLI resource is 2560 time slots.

[0225] In some possible examples, if the CLI resource in the first CLI resource is an RSSI resource, the range of the time domain period of the CLI resource in the first CLI resource is 10 time slots to 640 time slots. At this time, the minimum value of the time domain period of the first CLI resource is 10 time slots, and the maximum value of the time domain period of the first CLI resource is 640 time slots.

[0226] In some possible examples, if the CLI resource in the first CLI resource is an SRS resource, a time domain period of the CLI resource in the first CLI resource ranges from 1 slot to 2560 slots. At this time, a minimum value of the time domain period of the first CLI resource is 1 slot, and a maximum value of the time domain period of the first CLI resource is 2560 slots.

[0227] In some possible examples, if the CLI resource in the first CLI resource is associated with a CSI resource, a time domain period of the CLI resource in the first CLI resource ranges from 4 slots to 640 slots. At this time, a minimum value of the time domain period of the first CLI resource is 4 slots, and a maximum value of the time domain period of the first CLI resource is 640 slots.

[0228] In some possible examples, a minimum value of the time domain offset of the first CLI resource is less than or equal to 10 time units, and / or a maximum value of the time domain offset of the first CLI resource is greater than or equal to 640 time units.

[0229] In this way, by the minimum value of the time domain offset and / or the maximum value of the time domain offset of the first CLI resource, the embodiment can determine a range of the time domain offset of the first CLI resource.

[0230] It should be noted that the network device can configure one value in the range of the time domain offset of the first CLI resource to the terminal device through a high-layer parameter (such as CLI resource configuration information, CLI-ResourceConfig information, or CSI-ResourceConfig information) in high-layer signaling. At this time, the time period of the first CLI resource is the value.

[0231] For the minimum value of the time domain offset of the first CLI resource being less than 10 time units, one possible way is that the minimum value of the time domain offset of the first CLI resource is 1 time unit or 4 time units. For the minimum value of the time domain offset of the first CLI resource being greater than 640 time units, one possible way is that the maximum value of the time domain offset of the first CLI resource is 2560 time units.

[0232] In addition, the time unit can represent a basic unit on a time domain resource. For example, the time unit can be a slot, a symbol, or a mini-slot.

[0233] For example, taking a time unit of a slot as an example, the range of the time domain offset of the first CLI resource of the embodiment can be 10 slots to 640 slots. At this time, the minimum value of the time domain offset of the first CLI resource is 10 slots, and the maximum value of the time domain offset of the first CLI resource is 640 slots.

[0234] For example, taking a time unit as a time slot, the range of the time domain offset of the first CLI resource in this embodiment can be 4 time slots to 640 time slots. At this time, the minimum value of the time domain offset of the first CLI resource is 4 time slots, and the maximum value of the time domain offset of the first CLI resource is 640 time slots.

[0235] For example, taking a time unit as a time slot, the range of the time domain offset of the first CLI resource in this embodiment can be 1 time slot to 2560 time slots. At this time, the minimum value of the time domain offset of the first CLI resource is 1 time slot, and the maximum value of the time domain offset of the first CLI resource is 2560 time slots.

[0236] In some possible examples, if the CLI resource in the first CLI resource is an RSSI resource, the range of the time domain offset of the CLI resource in the first CLI resource is 10 time slots to 640 time slots. At this time, the minimum value of the time domain offset of the first CLI resource is 10 time slots, and the maximum value of the time domain offset of the first CLI resource is 640 time slots.

[0237] In some possible examples, if the CLI resource in the first CLI resource is an SRS resource, the range of the time domain offset of the CLI resource in the first CLI resource is 1 time slot to 2560 time slots. At this time, the minimum value of the time domain offset of the first CLI resource is 1 time slot, and the maximum value of the time domain offset of the first CLI resource is 2560 time slots.

[0238] In some possible examples, if the CLI resource in the first CLI resource is associated with a CSI resource, the range of the time domain offset of the CLI resource in the first CLI resource is 4 time slots to 640 time slots. At this time, the minimum value of the time domain offset of the first CLI resource is 4 time slots, and the maximum value of the time domain offset of the first CLI resource is 640 time slots.

[0239] The type D QCL assumption of the first CLI resource is described below.

[0240] For determining the first CLI resource in S1010, one possible implementation is to determine the type D QCL assumption of the first CLI resource. For determining the type D QCL assumption of the first CLI resource, one possible implementation is that the network device sends QCL configuration information, and the QCL configuration information is used to configure the type D QCL assumption of the first CLI resource; correspondingly, the terminal device receives the QCL configuration information.

[0241] It can be seen that the type D QCL assumption of the first CLI resource is configured by the configuration information.

[0242] For determining the Type-D QCL assumption of the first CLI resource, one possible implementation is that the Type-D QCL assumption of the first CLI resource is determined to be the same as the Type-D QCL assumption of the SRS resource associated with the first CLI resource by standard protocol, predefinition, pre-configuration, default, etc.

[0243] For example, if the CLI resource in the first CLI resource is an SRS resource, the Type-D QCL assumption of the first CLI resource is the same as the Type-D QCL assumption of the SRS resource associated with the first CLI resource.

[0244] For determining the Type-D QCL assumption of the first CLI resource, one possible implementation is that the Type-D QCL assumption of the first CLI resource is determined to be the same as the Type-D QCL assumption of the first CSI resource by standard protocol, predefinition, pre-configuration, default, etc., and the first CLI resource and the first CSI resource are associated with the same CSI report.

[0245] For example, for the CSI-ReportConfig information associated with the CSI-ResourceConfig information and the CLI resource configuration information, since the CSI-ReportConfig information configures one CSI report, the CSI-ResourceConfig information is used to configure the first CSI resource, and the CLI resource configuration information is used to configure the first CLI resource, one CSI report can be associated with the first CSI resource and the first CLI resource. At this time, the Type-D QCL assumption of the first CLI measurement resource is the same as the Type-D QCL assumption of the first CSI resource.

[0246] The following illustrates the report quantity corresponding to the first CSI report.

[0247] It should be noted that the CSI-ReportConfig information includes a report quantity. That is, the report quantity corresponding to the CSI report configured by the CSI-ReportConfig information. The report quantity can indicate the CSI related measurement result reported by the terminal device. In this way, when the terminal device sends the CSI report to the network device, the CSI report needs to carry the CSI related measurement result indicated by the report quantity.

[0248] For CLI measurement reporting based on the CSI measurement reporting framework, the present embodiment introduces a first parameter and a second parameter for the report quantity in the CSI-ReportConfig information.

[0249] The first parameter indicates that the CSI report contains a CLI resource index and SRS-RSRP. In this way, the CLI resource index and SRS-RSRP can be reported through the CSI report. The CLI resource index indicated by the first parameter is an RSRP resource index.

[0250] The second parameter indicates that the CSI report contains a CLI resource index and CLI-RSSI. In this way, the CLI resource index and CLI-RSSI can be reported through the CSI report. The CLI resource index indicated by the second parameter is an RSSI resource index.

[0251] For example, the first parameter is represented by CLI-ResourceID-RSRP or SRS-ResourceID-RSRP (abbreviated as SRI-RSRP), and the second parameter is represented by CLI-ResourceID-RSSI or CLI-RSSI-ResourceID-RSSI (abbreviated as CLIRI-RSSI).

[0252] In this way, the reporting parameter of the CSI-ReportConfig information contains the first parameter or the second parameter, and the embodiment can realize CLI reporting based on the CSI measurement reporting framework.

[0253] It should be noted that the first parameter indicates a CLI resource index and SRS-RSRP, which can be understood as the first parameter indicating a CLI related parameter reported by the terminal device, and the CLI related parameter includes a CLI resource index and SRS-RSRP. In this way, when the terminal device sends a CSI report to the network device, the CSI report needs to carry the CLI related parameter indicated by the first parameter.

[0254] The second parameter indicates a CLI resource index and CLI-RSSI, which can be understood as the second parameter indicating a CLI related parameter reported by the terminal device, and the CLI related parameter includes a CLI resource index and CLI-RSSI. In this way, when the terminal device sends a CSI report to the network device, the CSI report needs to carry the CLI related parameter indicated by the second parameter.

[0255] Based on this, for the reporting parameter corresponding to the first CSI report, one possible implementation manner is that the reporting parameter corresponding to the first CSI report contains the first parameter or the second parameter. In this way, the CLI measurement reporting based on the CSI measurement reporting framework is realized through the first CSI report. If the reporting parameter corresponding to the first CSI report contains the first parameter, the first CSI report needs to carry the CSL related parameter indicated by the first parameter. If the reporting parameter corresponding to the first CSI report contains the second parameter, the first CSI report needs to carry the CSL related parameter indicated by the second parameter.

[0256] The CSI information carried by the first CSI report is described below.

[0257] For the CLI information, one possible implementation is that the CLI information includes at least one of the following: resource index information, signal quality information corresponding to the resource index information, or capability index information corresponding to the resource index information.

[0258] The resource index information indicates an index of at least one CLI resource in the first CLI resource; the signal quality information indicates a signal quality value corresponding to the at least one CLI resource; and the capability index information indicates an index of an uplink antenna panel corresponding to the at least one CLI resource.

[0259] It should be noted that when the CLI resource in the first CLI resource is an SRS resource, the resource index information indicates an index of at least one SRS resource in the first CLI resource, the signal quality information indicates a signal quality value (such as SRS-RSRP) corresponding to the at least one SRS resource, and the capability index information indicates an index of an uplink antenna panel corresponding to the at least one SRS resource.

[0260] When the CLI resource in the first CLI resource is an RSSI resource, the resource index information indicates an index of at least one RSSI resource in the first CLI resource, the signal quality information indicates a signal quality value (such as CLI-RSSI) corresponding to the at least one RSSI resource, and the capability index information indicates an index of an uplink antenna panel corresponding to the at least one RSSI resource.

[0261] In addition, when the first CLI resource includes multiple CLI resources, the terminal device performs CLI measurement according to the first CLI resource to obtain a signal quality value corresponding to each CLI resource in the multiple CLI resources. Among them, the terminal device can only need to report the signal quality value corresponding to at least one CLI resource in the multiple CLI resources.

[0262] For the at least one CLI resource, one possible implementation is that the network device indicates the index of the at least one CLI resource to the terminal device through high-layer signaling. In this way, the terminal device only reports the signal quality value corresponding to the at least one CLI resource according to the network indication.

[0263] For the at least one CLI resource, one possible implementation is that the signal quality value corresponding to the at least one CLI resource is the largest. That is, the terminal device can only need to select one or more signal quality values with the largest value from the signal quality values corresponding to each CLI resource in the multiple CLI resources for reporting.

[0264] For the at least one CLI resource, one possible implementation is that the signal quality value corresponding to the at least one CLI resource is randomly selected. That is, the terminal device can only need to randomly select one or more signal quality values within the signal quality value corresponding to each of the plurality of CLI resources for reporting.

[0265] For the signal quality value, one possible implementation is that, if the reporting parameter corresponding to the first CSI report includes the first parameter, the signal quality value includes L1-SRS-RSRP.

[0266] It should be noted that when the reporting parameter corresponding to the first CSI report includes the first parameter, it means that the terminal device needs to report the SRS resource index and the SRS-RSRP through the CSI report. Here, the L1-SRS-RSRP refers to the L1 SRS-RSRP, which does not need to pass through the L3 filter.

[0267] For the signal quality value, one possible implementation is that, if the reporting parameter corresponding to the first CSI report includes the second parameter, the signal quality value includes L1-CLI-RSSI.

[0268] It should be noted that when the reporting parameter corresponding to the first CSI report includes the second parameter, it means that the terminal device needs to report the RSSI resource index and the CLI-RSSI through the CSI report. Here, the L1-CLI-RSSI refers to the L1 CLI-RSSI, which does not need to pass through the L3 filter.

[0269] For the signal quality value, one possible implementation is that the signal quality value includes an absolute signal quality value and / or at least one differential signal quality value based on the absolute signal quality value.

[0270] It should be noted that since the terminal device can obtain one or more signal quality values according to the first CLI resource. For example, one or more SRS-RSRPs are obtained by performing CLI measurement according to the SRS resource, or one or more CLI-RSSIs are obtained by performing CLI measurement according to the RSSI resource.

[0271] If one signal quality value is obtained, the absolute signal quality value can be the one signal quality value. If multiple signal quality values are obtained, the absolute signal quality value can be the maximum value or an arbitrary value among the multiple signal quality values. At this time, for the other signal quality values among the multiple signal quality values except the absolute signal quality value, a difference value between the other signal quality value and the absolute signal quality value can be calculated to obtain at least one differential signal quality value, i.e., at least one differential signal quality value based on the absolute signal quality value. That is, the differential signal quality value represents the difference value between the absolute signal quality value and the other signal quality value. In addition, the absolute signal quality value can include the absolute SRS-RSRP or the absolute CLI-RSSI, and the at least one differential signal quality value based on the absolute signal quality value can include at least one differential SRS-RSRP based on the absolute SRS-RSRP or at least one CLI-RSSI based on the absolute CLI-RSSI.

[0272] For the bit width of the absolute signal quality value, one possible implementation is that the bit width of the absolute signal quality value is 7 bits, or the bit width of the absolute signal quality value is greater than 7 bits.

[0273] For example, the bit width of the absolute SRS-RSRP is 7 bits, or the bit width of the absolute SRS-RSRP is greater than 7 bits.

[0274] For example, the bit width of the absolute CLI-RSSI is 7 bits, or the bit width of the absolute CLI-RSSI is greater than 7 bits.

[0275] For the bit width of the differential signal quality value, one possible implementation is that the bit width of the differential signal quality value in the at least one differential signal quality value is 4 bits, or the bit width of the differential signal quality value in the at least one differential signal quality value is greater than 4 bits.

[0276] For example, the bit width of the differential SRS-RSRP is 4 bits, or the bit width of the differential SRS-RSRP is greater than 4 bits.

[0277] For example, the bit width of the differential CLI-RSSI is 4 bits, or the bit width of the differential CLI-RSSI is greater than 4 bits.

[0278] For the bit width of the resource index, one possible implementation is that the bit width of the resource index is K represents the number of CLI resources in the first CLI resource.

[0279] For the capability index information, one possible implementation is that the bit width of the capability index information is 2, or the bit width of the capability index information is greater than 2.

[0280] For example, for the CLI resource in the first CLI resource being an SRS resource, the bit width of the resource index information, the signal quality information and the capability index information are shown in Table 1. In Table 1, K SRS represents the number of SRS resources in the first CLI resource.

[0281] Table 1

[0282] For example, for the CLI resource in the first CLI resource being an RSSI resource, the bit width of the resource index information, the signal quality information and the capability index information are shown in Table 2. In Table 2, K RSSI represents the number of RSSI resources in the first CLI resource.

[0283] Table 2

[0284] For the ordering of the absolute signal quality value and the at least one differential signal quality value in the first CSI report, one possible implementation is that, if the signal quality information comprises the absolute signal quality value and the at least one differential signal quality value, the absolute signal quality value is ordered before the at least one differential absolute signal quality value in the first CSI report.

[0285] For example, taking the case that the at least one differential signal quality value comprises three differential signal quality values as an example, it is shown in Table 3. Wherein, the absolute signal quality value is denoted as signal quality value #1, and the four differential signal quality values are denoted as differential signal quality value #2, differential signal quality value #3 and differential signal quality value #4. Wherein, the absolute signal quality value #1, the differential signal quality value #2, the differential signal quality value #2 and the differential signal quality value #3 are ordered in the first CSI report in turn.

[0286] Table 3

[0287] For the ordering of the resource index information and the signal quality information in the first CSI report, one possible implementation is that, if the CLI information comprises the resource index information and the signal quality information, the resource index information is ordered before the signal quality information in the first CSI report.

[0288] For example, the resource index information includes 4 SRS resource indexes in the first CLI resource, and the signal quality information includes one absolute SRS-RSRP and 3 differential SRS-RSRPs corresponding to the 4 SRS resource indexes, as shown in Table 4. Among them, the 4 SRS resource indexes are respectively denoted as SRI#1, SRI#2, SRI#3 and SRI#4, the absolute SRS-RSRP is denoted as RSRP#1, and the 3 differential SRS-RSRPs are respectively denoted as differential RSRP#2, differential RSRP#3 and differential RSRP#4. Among them, SRI#1, SRI#2, SRI#3, SRI#4, RSRP#1, RSRP#2, differential RSRP#3 and differential RSRP#4 are arranged in the first CSI report in turn,

[0289] Table 4

[0290] For example, the resource index information includes 4 SRS resource indexes in the first CLI resource, and the signal quality information includes one absolute SRS-RSRP and 3 differential SRS-RSRPs corresponding to the 4 SRS resource indexes, as shown in Table 4. Among them, the 4 SRS resource indexes are respectively denoted as SRI#1, SRI#2, SRI#3 and SRI#4, the absolute SRS-RSRP is denoted as RSRP#1, and the 3 differential SRS-RSRPs are respectively denoted as differential RSRP#2, differential RSRP#3 and differential RSRP#4. Among them, SRI#1, SRI#2, SRI#3, SRI#4, RSRP#1, RSRP#2, differential RSRP#3 and differential RSRP#4 are arranged in the first CSI report in turn,

[0292] For example, the resource index information includes 4 SRS resource indexes in the first CLI resource, and the signal quality information includes one absolute SRS-RSRP and 3 differential SRS-RSRPs corresponding to the 4 SRS resource indexes, as shown in Table 4. Among them, the 4 SRS resource indexes are respectively denoted as SRI#1, SRI#2, SRI#3 and SRI#4, the absolute SRS-RSRP is denoted as RSRP#1, and the 3 differential SRS-RSRPs are respectively denoted as differential RSRP#2, differential RSRP#3 and differential RSRP#4. Among them, SRI#1, SRI#2, SRI#3, SRI#4, RSRP#1, RSRP#2, differential RSRP#3 and differential RSRP#4 are arranged in the first CSI report in turn,

[0293] For example, the resource index information includes 4 SRS resource indexes in the first CLI resource, the signal quality information includes one absolute SRS-RSRP and 3 differential SRS-RSRPs, and the 4 capability index information corresponding to the 4 SRS resource indexes is as shown in Table 6. Among them, the 4 SRS resource indexes are respectively denoted as SRI#1, SRI#2, SRI#3 and SRI#4, the absolute SRS-RSRP is denoted as RSRP#1, the 3 differential SRS-RSRPs are respectively denoted as differential RSRP#2, differential RSRP#3 and differential RSRP#4, and the 4 capability index information is respectively denoted as capability index information#1, capability index information#2, capability index information#3 and capability index information#4. Among them, SRI#1, SRI#2, SRI#3, SRI#4, RSRP#1, RSRP#2, differential RSRP#3, differential RSRP#4, capability index information#1, capability index information#2, capability index information#3 and capability index information#4 are arranged in the first CSI report in turn.

[0296] Table 7

[0297] The priority of the first CSI report is described below.

[0298] For the priority of the first CSI report, one possible implementation is: if the first CSI report and the second CSI report exist in a sending conflict, and the second CSI report carries CSI information, the priority of the first CSI report and the priority of the second CSI report are determined; if the priority of the first CSI report is lower than the priority of the second CSI report, it is determined that the second CSI report is sent in priority to the first CSI report, or it is determined that the first CSI report is not sent; if the priority of the first CSI report is higher than the priority of the second CSI report, it is determined that the first CSI report is sent in priority to the second CSI report.

[0299] It should be noted that for the priority of the second CSI report, the priority of the second CSI report is: Pri_2(y, k, c, s) = 3*N_cells*M_s*y + N_cells*M_s*k + M_s*c + s;

[0300] Wherein, y herein can take 0, 1, 2 or 3; wherein y = 0 indicates that the type of the carrying channel of the CSI report and the time domain periodicity are PUSCH channel carrying and aperiodic respectively; y = 1 indicates PUSCH channel carrying and semi-persistent; y = 2 indicates PUCCH channel carrying and semi-persistent; y = 3 indicates PUCCH channel carrying and periodic;

[0301] Herein, k can take 0 or 1; wherein k = 0 indicates that the content of the first CSI report includes RSRP or SINR; k = 1 indicates other CSI measurement content that is not RSRP / SINR;

[0302] Herein, c indicates the serving cell ID where the reference signal corresponding to the second CSI report is located;

[0303] Herein, s indicates the ID of the second CSI report.

[0304] For the priority of the first CSI report, the priority of the first CSI report is:

[0305] Pri_1(y, k, c, s) = 3*N_cells*M_s*y + N_cells*M_s*k + M_s*c + s; wherein, y herein can take 0, 1, 2 or 3; wherein y = 0 indicates that the type of the carrying channel of the CSI report and the time domain periodicity are PUSCH channel carrying and aperiodic respectively; y = 1 indicates PUSCH channel carrying and semi-persistent; y = 2 indicates PUCCH channel carrying and semi-persistent; y = 3 indicates PUCCH channel carrying and periodic;

[0306] k=2, where k=2 means the CLI information; where, from this part of the above formula, the sending priority of the first CSI report (i.e. Pri_1(y, k, c, s)) is lower than the sending priority of the second CSI report (i.e. Pri_2(y, k, c, s)).

[0307] Here, c represents the serving cell ID where the reference signal corresponding to the first CSI report is located;

[0308] Here, s represents the ID of the first CSI report.

[0309] It can be seen that, since k=0 or 1 in Pri_2(y, k, c, s) and k=2 in Pri_1(y, k, c, s), if the values of other parameters are the same, the sending priority of the first CSI report is lower than the sending priority of the second CSI report. In addition, since the values of the parameters in Pri_2(y, k, c, s) and Pri_1(y, k, c, s) can be different, the priority of the first CSI report can also be higher than the priority of the second CSI report.

[0310] For the sending priority of the first CSI report, one possible implementation is that, if the first CSI report and the second CSI report exist in sending conflict, and the second CSI report carries the CSI information, it is determined that the first CSI report is not sent.

[0311] In this way, if the first CSI report and the second CSI report exist in sending conflict, the first CSI report does not need to use the above formula to calculate the priority of the first CSI report, and it is considered that the priority of the first CSI report is the lowest, and the first CSI report is directly not sent.

[0312] For the sending priority of the first CSI report, one possible implementation is that, if the first CSI report and the second CSI report exist in sending conflict, and the second CSI report carries the CSI information, the priority of the first CSI report is lower than the priority of the second CSI report.

[0313] In this way, if the first CSI report and the second CSI report exist in sending conflict, the first CSI report does not need to use the above formula to calculate the priority of the first CSI report, and it is directly considered that the priority of the first CSI report is the lowest.
