Description

Channel state information reporting configuration indication method and device Technical Field

[0001] The embodiments of the present application relate to the field of communication technologies. Background Art

[0002] As 5G becomes more widespread across industries and is applied in more geographic areas, processing more advanced services requires very high data rates and denser networks, using more antennas, greater bandwidth, and more frequency bands. Consequently, the energy consumption of 5G equipment is increasing. According to operator statistics, the average energy consumption of a 5G base station is more than three times that of an LTE base station. Nearly 50% of the cost of deploying a 5G network for operators is electricity. More importantly, 5G base stations consume significant energy even during periods of inactivity. Therefore, network energy conservation is crucial for improving environmental sustainability, reducing environmental impact (e.g., reducing greenhouse gas emissions), and saving operating costs. Energy conservation in 5G networks is a pressing issue that needs to be addressed.

[0003] To achieve network energy conservation, Rel-18 launched a project to research various energy-saving technologies. During the discussion, network energy-saving technologies can be categorized into time-domain, frequency-domain, spatial-domain, and energy-domain energy conservation. Examples of spatial-domain energy conservation include dynamically adjusting the number of antennas, dynamically adjusting data transmission power, and introducing cell-based DTX / DRX technologies.

[0004] It should be noted that the above introduction to the technical background is merely intended to provide a clear and complete description of the technical solutions of this application and facilitate understanding by those skilled in the art. Simply because these solutions are described in the background technology section of this application, it should not be assumed that the above technical solutions are well known to those skilled in the art.

[0005] Summary of the Invention

[0006] However, the inventors have discovered that some wireless communication application scenarios (such as energy-saving mode) may have negative impacts. For example, when network devices dynamically adjust the number of antennas or transmission power, this may cause changes in the corresponding channels, resulting in inaccurate or untimely reporting of Channel State Information (CSI) from terminal devices, ultimately affecting transmission performance. How network devices configure and / or instruct terminal devices to report CSI is a key issue that currently needs to be addressed.

[0055] The following describes the scenarios of the embodiments of the present application through examples, but the present application is not limited thereto.

[0056] FIG1 is a schematic diagram of a communication system according to an embodiment of the present application, schematically illustrating a situation using a terminal device and a network device as an example. As shown in FIG1 , a communication system 100 may include a network device 101 and terminal devices 102 and 103. For simplicity, FIG1 illustrates only two terminal devices and one network device as an example, but the embodiments of the present application are not limited thereto.

[0057] In the embodiment of the present application, existing services or future services can be transmitted between the network device 101 and the terminal devices 102 and 103. For example, these services may include but are not limited to: enhanced mobile broadband (eMBB), massive machine type communication (mMTC), and ultra-reliable and low-latency communication (URLLC), etc.

[0058] It is worth noting that FIG1 shows that both terminal devices 102 and 103 are within the coverage range of network device 101, but the present application is not limited thereto. Both terminal devices 102 and 103 may not be within the coverage range of network device 101, or one terminal device 102 may be within the coverage range of network device 101 while the other terminal device 103 is outside the coverage range of network device 101.

[0059] In the embodiments of the present application, the high-layer signaling may be, for example, radio resource control (RRC) signaling; for example, an RRC message, including, for example, an MIB, system information, or a dedicated RRC message; or an RRC information element (RRC IE). The high-layer signaling may also be, for example, MAC (Medium Access Control) signaling; or a MAC control element (MAC CE). However, the present application is not limited thereto.

[0060] In mobile communication systems, terminal devices typically measure channel state information (CSI) based on instructions and configuration from network devices and then report the measured CSI to the network devices. When scheduling a terminal device, the network device can refer to this CSI to schedule the terminal device for transmission using the appropriate resources and transmission method. Different terminal devices may experience different physical channel conditions. Using a CSI feedback mechanism can effectively utilize resources, thereby improving overall network transmission efficiency.

[0061] In NR's CSI feedback mechanism, the terminal device measures and reports the reference signal based on the CSI configuration. CSI can be composed of the Channel Quality Indicator (CQI), Precoding Matrix Indicator (PMI), Channel Measurement Reference Signal Resource Indicator (CSI-RS Resource Indicator, CRI), Synchronization Signal / Physical Broadcast Channel (SS / PBCH) Resource Indicator (SSBRI), Layer Indicator (LI), and Rank Indication (RI).

[0062] In the NR CSI reporting framework, CSI reporting is performed by associating CSI reports with CSI resources. CSI reports can be configured into the following three types: periodic CSI (P-CSI) reports: transmitted only on the Physical Uplink Control Channel (PUCCH); semi-persistent CSI (SP-CSI) reports: transmitted on the PUCCH or Physical Uplink Shared Channel (PUSCH); and aperiodic CSI (AP-CSI) reports: transmitted only on the PUSCH.

[0063] For semi-persistent CSI reporting on PUCCH, the PUCCH resource used to transmit the CSI report is configured by reportConfigType. Semi-persistent reporting on PUCCH is activated by an activation command (MAC CE), which selects a semi-persistent reporting setting on PUCCH for the terminal device to use. When the terminal device sends PUCCH with HARQ-ACK information on the timeslot n corresponding to the PDSCH carrying the activation command, it should The first slot thereafter begins to apply the specified semi-persistent reporting setting, where μ is the sub-carrier spacing (SCS) configuration of the PUCCH.

[0064] The activation / deactivation of semi-persistent CSI reporting on the PUCCH can be signaled by a MAC subheader with a logical channel identifier (LCID) in the MAC CE. Figure 2 shows a schematic diagram of the SP-CSI on PUCCH activation / deactivation MAC CE. As shown in Figure 2, the MAC CE has a fixed size of 16 bits and contains the following fields:

[0065] -Serving cell ID: This field indicates the identifier of the serving cell used by the MAC CE. The field length is 5 bits.

[0066] -BWP ID: This field indicates the UL BWP applied by the MAC CE, which serves as the code point of the DCI bandwidth indicator field. The BWP ID field length is 2 bits;

[0067] -Si: Indicates the activation / deactivation status of the semi-persistent CSI reporting configuration in CSI-reportconfigtoaddmodlist. S0 represents a reporting configuration, which includes PUCCH resources for SP CSI reporting in a specified part of the bandwidth (BWP) and has the lowest CSI reporting configuration ID (CSI-reportconfigid) in the list with the type set to semiPersistentOnPUCCH; S1 represents another reporting configuration, which includes PUCCH resources for SP CSI reporting in a specified BWP and has the second lowest CSI-reportconfigid, and so on. If the number of reporting configurations in the list with the type set to semiPersistentOnPUCCH in the specified BWP is less than i+1, the MAC entity will ignore the Si field. The Si field is set to 1 to indicate that the corresponding semi-persistent CSI reporting configuration will be activated, and the Si field is set to 0 to indicate that the corresponding Semi-Persistent CSI reporting configuration will be deactivated;

[0068] -R: Reserved bit, set to 0.

[0069] The above schematically illustrates the MAC CE. Tables 1 and 2 below respectively illustrate the MAC subheader LCID and eLCID.

[0070] Table 1(Table 6.2.1-1 Values ​​of LCID for DL-SCH)

[0071] Table 2(Table 6.2.1-1b Values ​​of one-octet eLCID for DL-SCH)

[0072] The spatial / energy domain element adjustment technologies related to network energy saving can be divided into two types.

[0073] Figure 3 illustrates spatial / energy domain element adjustments. As shown on the left side of Figure 3, Type 1 adjustments enable or disable all antennas (factors) associated with a logical antenna port. In this method, the network device can disable all antennas (factors) corresponding to one or more antenna ports. While the transmission power of each port remains unchanged, the total number of antenna ports is reduced. Therefore, this adjustment directly affects the number of antenna ports.

[0074] As shown in the right part of Figure 3, Type 2 adjustment is to enable or disable some antenna factors associated with a logical antenna port. In this way, the network device can shut down some antennas (factors) corresponding to all antenna ports. After shutdown, the number of antenna ports remains unchanged, but the transmission power of each port decreases. Therefore, this adjustment affects the beamforming gain of the network device and thus affects the transmission power of the reference signal.

[0075] In network energy-saving scenarios, to mitigate channel mutations caused by network devices adjusting the number of antennas, a feasible solution is for the terminal device to simultaneously send multiple CSI results. Each CSI result corresponds to an antenna adjustment mode or antenna configuration scheme. This allows the network device to obtain CSI in a timely and accurate manner for data scheduling and also recommends antenna adjustment schemes for the network device.

[0076] In network energy-saving scenarios, terminal devices may send multiple CSIs simultaneously. These multiple CSIs may be included in the same CSI report or in different CSI reports. When a CSI reporting configuration includes multiple CSIs, the CSI reporting overhead may be very large, placing a heavy burden on the normal transmission of the terminal device. Therefore, in network energy-saving scenarios, indicating the CSI reporting configuration has become an urgent problem to be solved. The following explanation is based on the energy-saving scenario, but the present application is not limited to this and can be applied to any scenario involving channel state information reporting.

[0077] Embodiments of the first aspect

[0078] The embodiment of the present application provides a method for indicating channel state information reporting configuration, which is described from the perspective of a terminal device. FIG4 is a schematic diagram of a method for indicating channel state information reporting configuration according to an embodiment of the present application. As shown in FIG4 , the method includes:

[0079] 401. A terminal device receives first information from a network device, where the first information includes at least L sub-configurations of a CSI reporting configuration, where one sub-configuration of the L sub-configurations corresponds to one CSI.

[0080] 402. The terminal device receives second information from a network device, where the second information is at least used to indicate and / or trigger and / or activate at least one sub-configuration of the L sub-configurations.

[0081] It is worth noting that FIG4 above is merely a schematic illustration of an embodiment of the present application, and the present application is not limited thereto. For example, the execution order of the various operations may be appropriately adjusted, and other operations may be added or some operations may be reduced. Those skilled in the art may make appropriate modifications based on the above description, and are not limited to the description of FIG4 above.

[0082] In some embodiments, the terminal device sends a CSI report corresponding to at least one sub-configuration that is indicated and / or triggered and / or activated to the network device based on the first information and / or the second information.

[0083] In some embodiments, the first information may be used for CSI-RS resource configuration.

[0084] For example, the NZP CSI-RS resource configuration for channel measurement in network energy-saving spatial domain adjustment may include:

[0085] - The first resource configuration type (e.g., A1-1-revised type): A resource set in a resource setting contains multiple resources, where a resource is associated with only one spatial adaptation pattern;

[0086] - The second resource configuration type (e.g., A1-2-revised type): A resource set in a resource setting contains at least one resource, where a resource can be associated with one or more spatial adaptation patterns.

[0087] For another example, the NZP CSI-RS resource configuration for channel measurement in network energy-saving energy domain adjustment includes:

[0088] -The second resource configuration type (for example, A1-2-revised type): A resource set in a resource setting contains at least one resource, wherein a resource can be associated with one or more power offset values, that is, a resource can be associated with one or more energy domain adjustment patterns.

[0089] In some embodiments, the binding relationship between the spatial / energy domain adjustment type and the resource configuration can be at least one of the following: type 1 spatial domain adjustment only supports the second resource configuration type (for example, A1-2-revised type); type 2 spatial domain adjustment only supports the first resource configuration type (for example, A1-1-revised type); energy domain adjustment can support the second resource configuration type (for example, A1-2-revised type).

[0090] In some embodiments, a CSI reporting configuration includes multiple sub-configurations. For example, a CSI reporting configuration may include L sub-configurations, each of which corresponds to a spatial / energy domain adjustment mode and a CSI result. If L in the CSI reporting configuration is greater than 1, each sub-configuration includes identification information or indication parameters.

[0091] For example, one of the L subconfigurations includes at least one subconfiguration index / ID for representing the subconfiguration. The L subconfigurations correspond to multiple subconfiguration indexes / IDs, and the subconfiguration corresponding to the minimum value of these subconfiguration indexes / IDs is the reference subconfiguration. The reference subconfiguration may correspond to at least the following parameters: the maximum number of ports, and / or the nrOfport value in the CSI-RS resource configuration, and / or the powerControlOffset value in the CSI-RS resource configuration. The present application is not limited thereto.

[0092] For another example, one of the L sub-configurations includes at least a first parameter or a second parameter, wherein the first parameter includes type 1 spatial domain adjustment related parameters and / or type 1 energy domain adjustment related parameters, and the second parameter includes type 2 spatial domain adjustment related parameters or type 2 energy domain adjustment related parameters.

[0093] The type 1 spatial domain adjustment related parameters are related to network energy saving and are used for type 1 spatial domain adjustment using the second resource configuration type (e.g., A1-2-revised type). For example, the type 1 spatial domain adjustment related parameters include the following information: N1, N2 information of a single antenna panel, and / or N1, N2, Ng information of a multi-antenna panel; and / or port subset indication information based on a bitmap, wherein one bit of the bitmap corresponds to one port; and / or codebook subset restriction information; and / or rank restriction information; the present application is not limited thereto.

[0094] The type 1 energy domain adjustment related parameters are related to network energy saving and are used for type 1 energy domain adjustment using the second resource configuration type (e.g., A1-2-revised type). For example, the type 1 energy domain adjustment related parameters include at least one or more power offsets (powerControlOffset), for example, one power offset (powerControlOffset) corresponds to one CSI-RS resource in the associated CSI resource set, and the number of power offsets (powerControlOffset) is the same as the number of CSI-RS resources in the associated CSI resource set;

[0095] Alternatively, the type 1 energy domain adjustment related parameters include at least one power offset (powerControlOffset) offset, for example, the power offset (powerControlOffset) offset corresponds to all CSI-RS resources in the associated CSI resource set;

[0096] Alternatively, the type 1 energy domain adjustment related parameters include at least one power offset (powerControlOffset) index value, for example, the power offset index value corresponds to all CSI-RS resources in the associated CSI resource set.

[0097] The type 2 spatial domain adjustment related parameters are related to network energy saving and are used for type 2 spatial domain adjustment using the first resource configuration type (e.g., A1-1-revised type). For example, the type 2 spatial domain adjustment related parameters include at least one CSI-RS resource ID list. The CSI-RS resource ID list may include one CSI-RS resource ID or multiple CSI-RS resource IDs. Therefore, one sub-configuration may be associated with at least one CSI-RS resource ID.

[0098] The type 2 energy adjustment related parameters are related to network energy saving and are used for type 2 energy domain adjustment using the first resource configuration type (e.g., A1-1-revised type). For example, the type 2 energy domain adjustment related parameters include at least one CSI-RS resource ID list, and the CSI-RS resource ID list may include one CSI-RS resource ID or multiple CSI-RS resource IDs. Therefore, one sub-configuration may be associated with at least one CSI-RS resource ID.

[0099] In some embodiments, for example, the type 2 spatial domain adjustment-related parameters and the type 2 energy domain adjustment-related parameters are the same. For another example, the second parameter includes the type 2 spatial domain adjustment-related parameters or the type 2 energy domain adjustment-related parameters. For another example, the second parameter includes a CSI-RS resource ID list, and the CSI-RS resource ID list is used for both type 2 spatial domain adjustment and type 2 energy domain adjustment.

[0100] The following is an example to illustrate.

[0101] For example, the CSI reporting configuration includes four sub-configurations, the CSI reporting configuration is associated with a CSI-RS resource set, and the resource set includes eight CSI-RS resources. In the CSI reporting configuration, sub-configuration 0 corresponds to a CSI-RS resource ID list, namely, CSI-RS resource0 and CSI-RS resource1, sub-configuration 1 corresponds to a CSI-RS resource ID list, namely, CSI-RS resource2 and CSI-RS resource3, sub-configuration 2 corresponds to a CSI-RS resource ID list, namely, CSI-RS resource4 and CSI-RS resource5, and sub-configuration 3 corresponds to a CSI-RS resource ID list, namely, CSI-RS resource6 and CSI-RS resource7.

[0102] For example, the CSI-RS resource corresponding to each sub-configuration is configured with the same powerControlOffset or power ControlOffsetSS, and the CSI-RS resources corresponding to different sub-configurations may be configured with different powerControlOffsets or power ControlOffsetSS.

[0103] For example, CSI-RS resource0 and CSI-RS resource1 (corresponding to the same sub-configuration 0) are configured with powerControlOffset = 0dB, powerControlOffsetSS = 0dB, CSI-RS resource2 and CSI-RS resource3 (corresponding to the same sub-configuration 1) are configured with powerControlOffset = 3dB, powerControlOffsetSS = 3dB, CSI-RS resource4 and CSI-RS resource5 (corresponding to the same sub-configuration 2) are configured with powerControlOffset = -3dB, powerControlOffsetSS = 0dB, CSI-RS resource6 and CSI-RS resource7 (corresponding to the same sub-configuration 3) are configured with powerControlOffset = 6dB, powerControlOffsetSS = 3dB. The powerControlOffset is used for type 2 energy domain adjustment, and the powerControlOffsetSS is used for type 2 spatial domain adjustment. The CSI-RS resource ID corresponding to the sub-configuration in type 2 energy domain adjustment and type 2 spatial domain adjustment is the same.

[0104] In some embodiments, the first parameter includes parameters related to Type 1 spatial domain adjustment and parameters related to Type 1 energy domain, indicating that the adjustment indicated by the first parameter is a joint adjustment of Type 1 spatial domain and Type 1 energy domain. In some embodiments, the first parameter includes only parameters related to Type 1 spatial domain adjustment, indicating that the adjustment is a Type 1 spatial domain adjustment. In some embodiments, the first parameter includes only parameters related to Type 1 energy domain, indicating that the adjustment is a Type 1 energy domain adjustment.

[0105] In some embodiments, a sub-configuration cannot include both the first parameter and the second parameter. That is, a sub-configuration cannot include both type 1 spatial domain adjustment related parameters and type 2 spatial domain adjustment related parameters. Alternatively, a sub-configuration cannot include both type 1 energy domain adjustment related parameters and type 2 energy domain adjustment related parameters.

[0106] In some embodiments, for example, the L sub-configurations are configured by radio resource control signaling. The maximum value of L depends on the terminal device capability, and can be configured by radio resource control signaling, determined based on a predefined method, or determined based on a default rule.

[0107] For example, the upper layer configures the maxNrofSUBCONFIG parameter to determine the maximum value that can be configured for a sub-configuration in the CSI reporting configuration. Table 3 below provides an RRC configuration example for a sub-configuration.

[0108] Table 3

[0109] In some embodiments, the association between CSI-RS resource configuration and sub-configuration is as follows:

[0110] For example, for the first resource configuration type (e.g., A1-1-revised type), one or more CSI-RS resources in a CSI-RS resource set for channel measurement can be associated with the same sub-configuration provided in the CSI reporting configuration, that is, a sub-configuration in the CSI reporting configuration can be associated with one or more CSI-RS resources in a CSI-RS resource set for channel measurement; wherein the resources in the resource set for channel measurement have the same number of antenna ports.

[0111] For another example, for the second resource configuration type (e.g., A1-2-revised type), all CSI-RS resources (which may be one or more) in the CSI-RS resource set for channel measurement are associated with each sub-configuration provided in the CSI report configuration, that is, each CSI-RS resource is associated with all sub-configurations, and the resources in the resource set for channel measurement have the same number of antenna ports.

[0112] In some embodiments, the CSI reporting process for multiple sub-configurations is as follows: For a CSI reporting configuration containing L sub-configurations, a framework needs to be supported so that a terminal device can report N CSIs at a reporting time, where N CSIs are associated with N sub-configurations in L (where 1≤N≤L), and each CSI corresponds to one sub-configuration. Where N=1 represents a single CSI report, and N>1 represents multiple CSI reports.

[0113] For semi-continuous / aperiodic CSI reporting, the base station supports triggering / indicating / activating N CSI reports in L, where 1≤N≤L; the maximum values ​​of L and N depend on the terminal capabilities. The specific triggering mechanism is as follows:

[0114] - For PUSCH-based aperiodic CSI and semi-persistent CSI reporting, support for DCI-based triggering:

[0115] For example, a trigger state associated with N sub-configurations is indicated by the CSI request field in the existing DCI. Different trigger states can represent different subsets of the L sub-configurations. Wherein, the DCI is UE-specific (in this case, the traditional DCI format applies);

[0116] For example, for A-CSI-RS, the CPU and CSI-RS resource / port calculations depend on the indicated N sub-configurations.

[0117] - For PUCCH-based semi-persistent CSI reporting, support for MAC CE-based triggering:

[0118] For example, it supports selecting indication information of N sub-configurations in one MAC-CE.

[0119] In some embodiments, the first information is carried by RRC signaling, the CSI reporting configuration is for semi-persistent CSI reporting of PUCCH, and the second information is carried by MAC CE.

[0120] For example, the second information includes an LCID whose codepoint or index is greater than or equal to 35 and less than or equal to 46, or the second information includes an eLCID whose codepoint is greater than or equal to 0 and less than or equal to 226 and / or whose index is greater than or equal to 64 and less than or equal to 290.

[0121] In some embodiments, the MAC CE includes a first field and one or more second fields, the first field is used to indicate a CSI reporting configuration ID, and the second field is used to indicate whether a sub-configuration of the CSI reporting configuration ID is indicated / triggered / activated.

[0122] A first field has a width of Y bits; a second field has a width of 1 bit; the number of the one or more second fields is less than or equal to the number of sub-configurations of the CSI reporting configuration ID, and the second fields are mapped to the sub-configurations of the CSI reporting configuration ID in ascending order of the sub-configuration index of the CSI reporting configuration ID, the second field with the lowest index value or index value / codepoint being '0' corresponds to the sub-configuration with the lowest index value in the CSI reporting configuration ID, the second field with the second lowest index value or index value / codepoint being '1' corresponds to the sub-configuration with the second lowest index value in the CSI reporting configuration ID, and so on; a value of one of the second fields indicates that the corresponding sub-configuration is activated (for example, a value of 1), and another value indicates that the corresponding sub-configuration is deactivated (for example, a value of 0).

[0123] For example, the triggering / activation / indication MAC CE of the sub-configuration based on PUCCH semi-persistent CSI reporting is identified / confirmed by a MAC sub-header with LCID or eLCID, where the LCID Codepoint / Index is greater than or equal to 35 and less than or equal to 46, for example, the LCID may be 35 or 36, etc.; the Codepoint of the eLCID is greater than or equal to 0 and less than or equal to 226, and the Index is greater than or equal to 64 and less than or equal to 290, for example, the codepoint of the eLCID is 0 and the index is 64.

[0124] FIG5 is an example diagram of a MAC CE according to an embodiment of the present application. As shown in FIG5 , the MAC CE has a fixed length of X bits, as follows:

[0125] -Serving cell ID: This field indicates the identifier of the serving cell used by the MAC CE, and the field length is 5 bits.

[0126] -BWP ID: This field indicates the UL BWP applied by the MAC CE, which is the code point of the specified DCI bandwidth part indication field. The BWP ID field length is 2 bits.

[0127] -CSI reporting configuration ID (CSI report config ID): This field is the first field and is used to indicate a CSI reporting configuration ID. The CSI reporting configuration is semi-persistent CSI reporting based on PUCCH, and the CSI reporting configuration includes L sub-configurations. This field is used to indicate the CSI reporting configuration ID including L sub-configurations, that is, the CSI reporting configuration ID used to indicate N sub-configurations among the L sub-configurations. The length of this field is Y bits. Taking the CSI reporting configuration ID, that is, the first field width of 2 bits as an example, 00 represents the first CSI reporting configuration ID, that is, the first PUCCH-based semi-persistent CSI reporting configuration ID for activation / deactivation, 01 represents the second CSI reporting configuration ID, that is, the second PUCCH-based semi-persistent CSI reporting configuration ID for activation / deactivation, and so on.

[0128] -S i : This field is the second field, used to indicate the activation / deactivation status of the L sub-configurations in the semi-persistent CSI reporting configuration based on PUCCH. i The number of units is greater than or equal to the number of sub-configurations L, that is, S i Equal to the maximum number of sub-configurations allowed to be configured. S0 corresponds to the sub-configuration with the lowest sub-configuration index / ID among the multiple sub-configurations contained in the CSI reporting configuration indicated by the first field on the indicated BWP, S1 corresponds to the sub-configuration with the second lowest sub-configuration index / ID among the multiple sub-configurations contained in the CSI reporting configuration indicated by the first field on the indicated BWP, and so on. If the number of sub-configurations contained in the CSI reporting configuration is less than i+1, the MAC entity will ignore S i Domain. S i If the domain is set to 1, the corresponding sub-configuration will be activated. i Setting a field to 0 indicates that the corresponding sub-configuration will be deactivated.

[0129] -R: Reserved bit, for example, set to 0.

[0130] In this way, it is possible to indicate one or more sub-configurations of a CSI reporting configuration.

[0131] Figure 5 illustrates an example of a MAC CE according to an embodiment of the present application. The width of the CSI report ID in Figure 5 is illustrated as 2 bits, but the present application is not limited thereto. The width of the CSI report config ID is greater than or equal to 1 bit and less than or equal to Y bits, where Y is a positive integer greater than 1, such as Y = 2.

[0132] FIG6 is another example diagram of a MAC CE according to an embodiment of the present application. As shown in FIG6, the location of the CSI reprot config ID can also be in other locations. i The units digit of is described with 4 (S0-S3) as an example, but the embodiments of the present application are not limited thereto.

[0133] FIG7 is another example diagram of a MAC CE according to an embodiment of the present application. As shown in FIG7 , S i The units digit of S is explained by taking 6 (S0~S5) as an example. i The number is greater than or equal to 1 and less than or equal to N, where N is a positive integer greater than 1, such as N=8.

[0134] In some embodiments, the MAC CE includes one or more second fields, where the second field is used to indicate whether a sub-configuration of the CSI reporting configuration ID is activated.

[0135] A second field is 1 bit; the number of one or more second fields is greater than or equal to the number of sub-configurations of the CSI reporting configuration ID, that is, the number of second fields is equal to the maximum number of allowed sub-configurations, and the second fields are mapped to the sub-configurations of the CSI reporting configuration ID in ascending order of the sub-configuration index of the CSI reporting configuration ID. The second field with the lowest index value or index value / codepoint of '0' corresponds to the sub-configuration with the lowest index value in the CSI reporting configuration ID, the second field with the second lowest index value or index value / codepoint of '1' corresponds to the sub-configuration with the second lowest index value in the CSI reporting configuration ID, and so on; one value of one of the second fields indicates that the corresponding sub-configuration is activated (for example, a value of 1), and the other value indicates that the corresponding sub-configuration is deactivated (for example, a value of 0).

[0136] For example, the CSI report config ID field can be removed from the MAC CEs shown in Figures 5 to 7. The terminal device and the network device configure a PUCCH-based semi-persistent CSI reporting configuration containing multiple sub-configurations by default. The terminal device has already received the CSI reporting configuration information from the network device, so the CSI report config ID does not need to be indicated in the MAC CE.

[0137] In this way, it is possible to indicate one or more sub-configurations of a CSI reporting configuration.

[0138] In some embodiments, the MAC CE includes multiple first fields and multiple second fields, wherein the multiple first fields are used to indicate multiple CSI reporting configuration IDs, and the sub-configuration of the CSI reporting configuration ID is indicated by one or more corresponding second fields to indicate activation or deactivation.

[0139] For example, the MAC CE includes N1 first fields and N1*M second fields, where one first field among the N1 first fields corresponds to M second fields, where N1>1 and M>1. The first field is used to indicate the CSI reporting configuration ID, and the second field is used to indicate whether a subconfiguration of the CSI reporting configuration ID is activated. The one CSI reporting configuration ID corresponds to M subconfigurations, and the value of M is greater than or equal to the number of subconfigurations in the CSI mountain configuration ID. That is, M is the maximum number of configurable subconfigurations in a CSI reporting configuration.

[0140] For example, the triggering / activation / indication MAC CE of the sub-configuration based on PUCCH semi-persistent CSI reporting is identified / confirmed by a MAC sub-header with LCID or eLCID, where the LCID Codepoint / Index is greater than or equal to 35 and less than or equal to 46, for example, the LCID may be 35 or 36, etc.; the Codepoint of the eLCID is greater than or equal to 0 and less than or equal to 226, and the Index is greater than or equal to 64 and less than or equal to 290, for example, the codepoint of the eLCID is 0 and the index is 64.

[0141] FIG8 is another example diagram of a MAC CE according to an embodiment of the present application. As shown in FIG8 , the MAC CE has a fixed length of X bits, as follows:

[0142] -Serving cell ID: This field indicates the identifier of the serving cell used by the MAC CE, and the field length is 5 bits.

[0143] -BWP ID: This field indicates the UL BWP applied by the MAC CE, which is the code point of the specified DCI bandwidth part indication field. The BWP ID field length is 2 bits.

[0144] -CSI reporting configuration ID i(CSI report configID i): This field is the first field, that is, one CSI reporting configuration among N1 CSI reporting configurations containing multiple sub-configurations. CSI report config ID0 represents the first CSI reporting configuration used for sub-configuration indication, CSI report config ID1 represents the second CSI reporting configuration used for sub-configuration indication, and so on. The length of this field is Y bits. Taking the width of each CSI report config ID as an example of 2 bits, 00 represents the first CSI reporting configuration ID, that is, the first PUCCH-based semi-persistent CSI reporting configuration ID for activation / deactivation, 01 represents the second CSI reporting configuration ID, that is, the second PUCCH-based semi-persistent CSI reporting configuration ID for activation / deactivation, and so on.

[0145] -Si i : This field is the second field, indicating the activation / deactivation status of the L sub-configurations in the semi-persistent CSI reporting configuration based on PUCCH. S0 i The corresponding CSI reporting configuration ID of the indicated BWP is the i-th CSI reporting configuration ID (CSI reporting configuration ID i The subconfiguration with the lowest subconfiguration index / ID among the multiple subconfigurations contained in (CSI report configID i)), S1 i Corresponding to the i-th CSI reporting configuration on the indicated BWP (CSI reporting configuration ID i The sub-configuration with the second lowest sub-configuration index / ID among the multiple sub-configurations contained in (CSI report configID i)), and so on. The i-th CSI reporting configuration refers to the CSI reporting configuration ID i The ith CSI report config ID in the CSI report configuration. If the number of sub-configurations contained in the CSI report configuration is less than i+1, the MAC entity will ignore the Si field. Setting the Si field to 1 indicates that the corresponding sub-configuration will be activated, and setting the Si field to 0 indicates that the corresponding sub-configuration will be deactivated.

[0146] -R: Reserved bit, for example, set to 0.

[0147] In this way, it is possible to simultaneously indicate multiple sub-configurations of multiple CSI reporting configurations.

[0148] In some embodiments, the MAC CE includes a first field, one or more third fields, and a fourth field. The first field is used to indicate a CSI reporting configuration ID, one of the third fields is used to indicate a sub-configuration ID of the CSI reporting configuration ID, and the fourth field is used to indicate whether the sub-configuration is activated or deactivated.

[0149] The fourth field is 1 bit; one value of the fourth field indicates that all sub-configurations corresponding to one or more sub-configuration IDs are activated (for example, a value of 1), and another value indicates that all sub-configurations corresponding to the one or more sub-configuration IDs are deactivated (for example, a value of 0).

[0150] For example, the triggering / activation / indication MAC CE of the sub-configuration based on PUCCH semi-persistent CSI reporting is identified / confirmed by a MAC sub-header with LCID or eLCID, where the LCID Codepoint / Index is greater than or equal to 35 and less than or equal to 46, for example, the LCID may be 35 or 36, etc.; the Codepoint of the eLCID is greater than or equal to 0 and less than or equal to 226, and the Index is greater than or equal to 64 and less than or equal to 290, for example, the codepoint of the eLCID is 0 and the index is 64.

[0151] FIG9 is another example diagram of a MAC CE according to an embodiment of the present application. As shown in FIG9 , the MAC CE has a fixed length of X bits, as follows:

[0152] -A / D: This field is the fourth field and is used to indicate whether to activate or deactivate the sub-configuration included in the CSI reporting configuration. For example, if this field is set to 1, it indicates activation, and if it is set to 0, it indicates deactivation.

[0153] -Serving cell ID: This field indicates the identifier of the serving cell used by the MAC CE, and the field length is 5 bits.

[0154] -BWP ID: This field indicates the UL BWP applied by the MAC CE, which is the code point of the specified DCI bandwidth part indication field. The BWP ID field length is 2 bits.

[0155] -CSI reporting configuration ID (CSI report config ID): This field is the first field and is used to indicate the index of a CSI reporting configuration. The CSI reporting configuration is semi-persistent CSI reporting based on PUCCH, and the CSI reporting configuration includes L sub-configurations. This field is used to indicate the CSI reporting configuration ID including L sub-configurations, that is, the CSI reporting configuration ID for indicating N sub-configurations among the L sub-configurations. The length of this field is Y bits. Taking the CSI reporting configuration ID width of 2 bits as an example, 00 represents the first CSI reporting configuration ID, that is, the first PUCCH-based semi-persistent CSI reporting configuration ID for activation / deactivation, 01 represents the second CSI reporting configuration ID, that is, the second PUCCH-based semi-persistent CSI reporting configuration ID for activation / deactivation, and so on.

[0156] -Sub-configuration ID: This field is the third field and is used to indicate the index / ID of the sub-configuration in a CSI reporting configuration, that is, to indicate the sub-configuration to be activated or deactivated. If A / D is set to 1, it indicates that the sub-configuration corresponding to the sub-configuration in the sub-configuration ID field is activated. If A / D is set to 0, it indicates that the sub-configuration corresponding to the sub-configuration in the sub-configuration ID field is deactivated. The length of this field is Z bits. Z is a positive integer greater than 0 and less than 7, for example, Z = 2.

[0157] -R: Reserved bit, for example, set to 0.

[0158] In this way, it is possible to indicate one or more sub-configurations of a CSI reporting configuration.

[0159] In some embodiments, the MAC CE includes a first field and one or more third fields; the first field is used to indicate a CSI reporting configuration ID, and one of the third fields is used to indicate a sub-configuration ID of the CSI reporting configuration ID.

[0160] The sub-configurations corresponding to the one or more sub-configuration IDs are all activated, or the sub-configurations corresponding to the one or more sub-configuration IDs are all deactivated.

[0161] For example, the A / D field can be removed from the MAC CE shown in Figure 9, and the A / D field position can be R. Because sub-configuration deactivation is not required for sub-configuration indication, all sub-configurations corresponding to the default sub-configuration ID are activated. In multiple sub-configuration indications, the subsequent sub-configuration indication information can overwrite the previous sub-configuration indication information; in addition, when the CSI reporting is deactivated, the sub-configuration indication information becomes invalid.

[0162] In some embodiments, the MAC CE includes one or more third fields and a fourth field, wherein the third field is used to indicate one or more sub-configuration IDs of the CSI reporting configuration ID, and the fourth field is used to indicate whether the sub-configuration is activated or deactivated, and the CSI reporting configuration ID is predefined or preconfigured and includes multiple sub-configurations.

[0163] The fourth field is 1 bit; one value of the fourth field indicates that all sub-configurations corresponding to the one or more sub-configuration IDs are activated, and another value indicates that all sub-configurations corresponding to the one or more sub-configuration IDs are deactivated.

[0164] For example, the CSI report config ID field can be removed from the MAC CE shown in Figure 9. The terminal device and the network device configure a PUCCH-based semi-persistent CSI reporting with multiple sub-configurations by default. The terminal device has already received the CSI reporting configuration information from the network device, so the CSI report config ID does not need to be reflected in the MAC CE.

[0165] In some embodiments, the MAC CE includes a first field and one or more third fields, the first field is used to indicate a CSI reporting configuration ID, and the third field is used to indicate a sub-configuration ID of the CSI reporting configuration ID, and the CSI reporting configuration ID is predefined or preconfigured and includes multiple sub-configurations.

[0166] The sub-configurations corresponding to the one or more sub-configuration IDs are all activated, or the sub-configurations corresponding to the one or more sub-configuration IDs are all deactivated.

[0167] For example, the CSI report config ID field and the A / D field may be removed from the MAC CE shown in Figure 9. The sub-configurations corresponding to the sub-configuration IDs in the MAC CE are all activated by default, or the sub-configurations corresponding to the sub-configuration IDs in the MAC CE are all deactivated by default.

[0168] In some embodiments, the MAC CE includes or corresponds to multiple first fields and multiple third fields, one first field is used to indicate a CSI reporting configuration ID, one third field is used to indicate a sub-configuration ID of the CSI reporting configuration ID, and one CSI reporting configuration ID corresponds to one or more sub-configuration IDs.

[0169] The sub-configurations of the multiple CSI reporting configuration IDs are indicated by a fourth field as being activated or deactivated, or the sub-configurations of the multiple CSI reporting configuration IDs are defaulted to being activated or deactivated.

[0170] For example, the triggering / activation / indication MAC CE of the sub-configuration based on PUCCH semi-persistent CSI reporting is identified / confirmed by a MAC sub-header with LCID or eLCID, where the LCID Codepoint / Index is greater than or equal to 35 and less than or equal to 46, for example, the LCID may be 35 or 36, etc.; the Codepoint of the eLCID is greater than or equal to 0 and less than or equal to 226, and the Index is greater than or equal to 64 and less than or equal to 290, for example, the codepoint of the eLCID is 0 and the index is 64.

[0171] FIG10 is another example diagram of a MAC CE according to an embodiment of the present application. As shown in FIG10 , the MAC CE has a fixed length of X bits, as follows:

[0172] -A / D: This field indicates whether the sub-configuration included in the CSI reporting configuration is activated or deactivated; for example, if this field is set to 1, it indicates activation, and if it is set to 0, it indicates deactivation.

[0173] -Serving cell ID: This field indicates the identifier of the serving cell used by the MAC CE. The length of this field is 5 bits.

[0174] -BWP ID: This field indicates the UL BWP applied by the MAC CE, which is the code point of the specified DCI bandwidth part indication field. The BWP ID field length is 2 bits.

[0175] -CSI reporting configuration ID i (CSI report configID i ): This field is the first field, which is used to indicate a CSI reporting configuration ID among multiple CSI reporting configuration IDs, where each CSI reporting configuration ID contains multiple configurations. CSI report config ID0 represents the first CSI reporting configuration used for sub-configuration indication, CSI report config ID1 represents the second CSI reporting configuration used for sub-configuration indication, and so on. The length of this field is Y bits. Taking the width of each CSI report config ID as 2 bits, for example, 00 represents the first CSI reporting configuration ID, that is, the first PUCCH-based semi-persistent CSI reporting configuration ID for activation / deactivation, 01 represents the second CSI reporting configuration ID, that is, the second PUCCH-based semi-persistent CSI reporting configuration ID for activation / deactivation, and so on.

[0176] -Subconfiguration ID i (sub-configuration ID i): This field contains the i-th CSI reporting configuration (CSI reporting configuration ID i The index / ID of the sub-configuration to be activated or deactivated in (CSI report configID i). If A / D is set to 1, it indicates the i-th CSI reporting configuration (CSI reporting configuration ID i The corresponding sub-configuration in the sub-configuration ID field in (CSI report configID i)) is activated. If A / D is set to 0, it means that the i-th CSI reporting configuration (CSI reporting configuration ID i The sub-configuration corresponding to the sub-configuration ID field in (CSI report configID i)) is deactivated. The length of this field is Z bits. The i-th CSI reporting configuration refers to the CSI reporting configuration ID i The i-th CSI report config ID in . The Z is a positive integer greater than 0 and less than 7, for example, Z=2.

[0177] -R: Reserved bit, for example, set to 0.

[0178] In this way, it is possible to simultaneously indicate multiple sub-configurations of multiple CSI reporting configurations.

[0179] The above schematically illustrates the MAC CE of the activation / deactivation sub-configuration in an embodiment of the present application. The present application is not limited to this. For example, the MAC CE may include both information on the activation / deactivation sub-configuration and information on the activation / deactivation CSI reporting configuration.

[0180] In some embodiments, the MAC CE further includes one or more fifth fields for indicating whether the CSI reporting configuration is activated.

[0181] For example, the triggering / activation / indication MAC CE of the sub-configuration based on PUCCH semi-persistent CSI reporting is identified / confirmed by a MAC sub-header with LCID or eLCID, where the LCID Codepoint / Index is greater than or equal to 35 and less than or equal to 46, for example, the LCID may be 35 or 36, etc.; the Codepoint of the eLCID is greater than or equal to 0 and less than or equal to 226, and the Index is greater than or equal to 64 and less than or equal to 290, for example, the codepoint of the eLCID is 0 and the index is 64.

[0182] FIG11 is another example diagram of a MAC CE according to an embodiment of the present application. As shown in FIG11 , the MAC CE has a fixed length of X bits, as follows:

[0183] -Serving cell ID: This field indicates the identifier of the serving cell used by the MAC CE, and the field length is 5 bits.

[0184] -BWP ID: This field indicates the UL BWP applied by the MAC CE, which is the code point of the specified DCI bandwidth part indication field. The BWP ID field length is 2 bits.

[0185] -Si: This field indicates the activation / deactivation status of the semi-persistent CSI reporting configuration in csi-ReportConfigToAddModList. S0 corresponds to the semi-persistent CSI reporting configuration that is indicated to contain PUCCH resources on the BWP and has the lowest CSI reporting configuration index in the csi-ReportConfigToAdd ModList list, S1 corresponds to the semi-persistent CSI reporting configuration that is indicated to contain PUCCH resources on the BWP and has the second lowest CSI reporting configuration index in the csi-ReportConfigToAddModList list, and so on. If the number of semi-persistent CSI reporting configurations in the list is less than i+1, the MAC entity will ignore S i Field. S i If set to 1, the corresponding CSI reporting configuration will be activated. i Setting it to 0 means that the corresponding CSI reporting configuration will be deactivated.

[0186] -CSI Report Configuration ID (CSI report config ID): This field is the first field and is the index of the semi-persistent CSI reporting configuration in csi-ReportConfigToAddModList, indicating that the CSI reporting configuration includes L sub-configurations. This field is used to represent the CSI reporting configuration ID containing L sub-configurations, that is, the CSI reporting configuration ID used to indicate N sub-configurations among the L sub-configurations. This field is 2 bits long. 00 corresponds to the CSI reporting configuration corresponding to S1, 01 corresponds to the CSI reporting configuration corresponding to S2, 10 corresponds to the CSI reporting configuration corresponding to S3, and 11 corresponds to the CSI reporting configuration corresponding to S4.

[0187] -P i :This field indicates the activation / deactivation status of the L sub-configurations in the semi-persistent CSI reporting configuration indicated by the CSI reporting configuration ID field. P0 corresponds to the sub-configuration with the lowest sub-configuration index / ID among the multiple sub-configurations contained in the CSI reporting configuration on the indicated BWP, P1 corresponds to the sub-configuration with the second lowest sub-configuration index / ID among the multiple sub-configurations contained in the CSI reporting configuration on the indicated BWP, and so on. If the number of sub-configurations contained in the CSI reporting configuration is less than i+1, the MAC entity will ignore the Si field. Pi If the field is set to 1, the corresponding sub-configuration will be activated. i Setting a field to 0 indicates that the corresponding sub-configuration will be deactivated.

[0188] -R: Reserved bit, for example, set to 0.

[0189] In this way, the activation / deactivation of the CSI reporting configuration and the activation / deactivation of the sub-configuration can be completed at the same time.

[0190] In Figure 11, only P i The activation / deactivation of the sub-configuration is described using the field as an example, but the present application is not limited thereto. For example, any one or more schemes for activation / deactivation of the sub-configuration in the above embodiments may be adopted.

[0191] The above embodiments are merely exemplary of the present invention, but the present invention is not limited thereto. Appropriate modifications may be made based on the above embodiments. For example, the above embodiments may be used alone, or one or more of the above embodiments may be combined.

[0192] It can be seen from the above embodiments that even in some scenarios of wireless communication applications (such as energy-saving mode), the network equipment can efficiently and accurately indicate the CSI reporting configuration of the terminal device, and can save CSI reporting overhead and uplink resources.

[0201] In some embodiments, the first information is carried by RRC signaling; and the CSI reporting configuration is for semi-persistent CSI reporting of PUCCH.

[0202] In some embodiments, the second information is carried by a MAC CE.

[0203] In some embodiments, the second information includes an LCID having a codepoint or an index greater than or equal to 35 and less than or equal to 46, or the second information includes an eLCID having a codepoint greater than or equal to 0 and less than or equal to 226 and / or an index greater than or equal to 64 and less than or equal to 290.

[0204] In some embodiments, the MAC CE includes a first field and one or more second fields, the first field is used to indicate a CSI reporting configuration ID, and the second field is used to indicate whether a sub-configuration of the CSI reporting configuration ID is indicated / triggered / activated.

[0205] In some embodiments, a first field has a width of Y bits; a second field has a width of 1 bit;
