Description

Channel state information reporting method, terminal equipment, base station and medium Technical Field

[0001] The present application relates to the field of communication technology, for example, to a channel state information reporting method, terminal equipment, base station and medium. Background Art

[0002] Due to the wide application of large-scale antennas in 5G communication systems, the energy consumption of base stations has increased significantly.

[0003] One effective way to save base station energy consumption is to turn off the antenna. After the antenna is turned off, the corresponding devices, such as the power amplifier, will be turned off to save energy. However, the switching of the antenna will cause the channel between the base station and the terminal (UE) to change. If the channel status is not updated in time, it may affect the data scheduling. Therefore, multiple sets of CSI information are reported in one CSI report. Each set of CSI information corresponds to an antenna shutdown mode. This can help the base station obtain more channel states under multiple antenna shutdown modes, and thus better perform data scheduling; another way to save base station energy consumption is to perform power adjustment. Multiple sets of CSI information are reported in one CSI report. Each set of CSI information corresponds to a power adjustment mode, which can help the base station better perform data scheduling.

[0004] Using the above method, the UE needs to support multiple sets of CSI reports. Multiple CSI reports require the UE to measure and calculate multiple sets of CSI information, which places high demands on the UE's capabilities. Some UEs may not be able to support multiple sets of CSI reports. If the UE cannot support multiple sets of CSI reports, the base station cannot configure the UE accordingly. Therefore, ensuring that the UE has the corresponding UE capabilities is crucial.

[0036] To make the purpose, technical solutions and advantages of this application more clear, the embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be noted that, unless there is a conflict, the embodiments and features in the embodiments of this application can be combined with each other in any way.

[0037] The steps shown in the flowcharts of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions. Also, although a logical order is shown in the flowcharts, in some cases, the steps shown or described can be performed in an order different from that shown here.

[0038] The UE reports multiple sets of CSI reports in a CSI reporting opportunity. The reports include multiple sets of CSI information, each set of CSI information is associated with a sub-configuration. A CSI-ReportConfig corresponds to a CSI reporting configuration, and the CSI-ReportConfig corresponding to multiple sets of CSI reporting configurations contains L (L>=1) sub-configurations.

[0039] Configuration Method 1: Figure 1a is a schematic diagram of a configuration method provided in an embodiment. As shown in Figure 1a, a sub-configuration is configured with at least a rank restriction (RI restriction), a codebook subset restriction, and a port subset indication. Each sub-configuration is associated with all channel state information reference signal (CSI-RS) resources in a resource set. The CSI-RS resource set is a resource set in the resource setting associated with the CSI-ReportConfig. Configuration Method 1 is a configuration method for adjusting multiple sets of CSI reports in the base station spatial domain. Different sub-configurations may be associated with different numbers of ports. The port subset indication indicates one or more CSI-RS ports.

[0040] Configuration Method 2: Figure 1b is a schematic diagram of another configuration method provided by an embodiment. As shown in Figure 1b, a sub-configuration is configured with at least a resource list; a resource list includes one or more CSI-RS resource identifiers; and a sub-configuration is associated with one or more CSI-RS resources. Configuration Method 2 is a configuration method for adjusting multiple sets of CSI reporting for the base station spatial domain. The number of CSI-RS resource ports is configured to be the same, and different sub-configurations are associated with different CSI-RS resources.

[0041] Configuration Mode 3: A sub-configuration must be configured with at least one of the following: one or more power offsets, one or more power deviation values, or one or more power offset indices. Configuration Mode 3 is a configuration mode for base station power adjustment of multiple CSI reporting functions. Different sub-configurations correspond to different power offsets. The power offset includes the assumed ratio of the EPRE per resource element capacity of the physical downlink shared channel (PDSCH) to the non-zero power NZP CSI-RS EPRE when the UE obtains CSI feedback, and / or the assumed ratio of the NZP-CSI-RS EPRE to the EPRE of the synchronization signal / physical broadcast channel block (SS / PBCH).

[0042] To use these configurations, the UE must support multiple sets of CSI reporting. Multiple CSI reporting requires the UE to measure and calculate multiple sets of CSI information, placing high demands on the UE's capabilities. If the UE does not support multiple sets of CSI reporting, the base station cannot configure the UE accordingly. Therefore, determining the UE's capabilities is a pressing technical challenge. Furthermore, the three aforementioned configuration methods are independent, so supporting joint configuration is also a pressing technical challenge.

[0043] In some embodiments, each sub-configuration represents an antenna shut-down mode. In some embodiments, each sub-configuration represents a power adjustment mode.

[0044] To solve the above technical problems, Figure 2 is a flowchart of a channel state information reporting method provided by an embodiment. As shown in Figure 2, a channel state information reporting method provided by this embodiment can be applied to a terminal device (ie, UE), including steps 110 to 130.

[0045] In step 110, UE capability signaling is sent, where the UE capability signaling instructs the UE to report supported UE capabilities.

[0046] In this embodiment, the UE may send UE capability signaling to the base station to inform the base station of the supported UE capabilities reported by the UE.

[0047] A UE capability may include one or more of the following combinations:

[0048] Indicates whether the UE supports configuring L sub-configurations in one CSI report configuration, where multiple types of parameters are configured in the L sub-configurations;

[0049] Indicates whether the UE supports reporting N sets of CSI in one CSI report;

[0050] Indicates the maximum L value supported by the UE; the candidate value of the maximum L value is at least one of the following: {2, 3, 4};

[0051] Indicates whether the UE supports multiple sets of CSI reporting for overhead saving;

[0052] Indicates whether the UE supports CSI processing unit (CPU) calculation for multiple sets of CSI reporting;

[0053] Indicates whether the UE supports CPU calculation of multiple sets of CSI reports to save overhead;

[0054] Indicates the CSI type in multiple sets of CSI reports supported by the UE; the CSI type can be at least one of the following: first type CSI, second type CSI, sub-block 1 of third type CSI, sub-block 2 of third type CSI;

[0055] Indicates the priority type supported by the UE;

[0056] Indicates the scaling factor of CPU calculation for overhead saving supported by the UE;

[0057] Indicates the minimum value of the scaling factor for CPU calculation for overhead saving supported by the UE;

[0058] Indicates the scaling factor for overhead saving supported by the UE;

[0059] Indicates the minimum value of the scaling factor for overhead saving supported by the UE;

[0060] The scaling factor value is a positive number greater than or equal to 1 and less than or equal to the maximum number of resources configurable in a resource set; the scaling factor value is a positive number;

[0061] Indicates whether the UE supports configuring multiple types of parameters in one sub-configuration of a CSI report;

[0062] Indicates whether the UE supports configuring different types of parameters in different sub-configurations of a CSI report;

[0063] Indicates whether the UE supports the UE capability of triggering N sub-configurations among L sub-configurations through downlink control information or medium access control (MAC) control elements.

[0064] In step 120, high-layer configuration signaling is received, where the high-layer configuration signaling includes configuration information of a CSI report, where the configuration information of the CSI report includes L sub-configurations, where L is an integer greater than or equal to 1, and the configuration information of the CSI report is configured based on the UE capability.

[0065] A set of CSI reports may include at least one of the following: CSI-RS resource indicator CRI; rank indicator RI; layer indicator LI; precoding matrix indicator PMI; channel quality indicator CQI.

[0066] In this embodiment, the UE receives the higher layer configuration signaling sent by the base station and reports the CSI report to the base station according to the configuration information of the CSI report. When the base station configures and schedules the UE, it needs to respect the UE radio access capability parameters notified by the UE capability signaling sent by the UE.

[0067] The configuration information of the CSI report includes L sub-configurations, each set of CSI information is associated with a sub-configuration, and the sub-configuration is a CSI report sub-configuration.

[0068] In step 130, CSI information is reported according to the higher layer configuration signaling.

[0069] In this embodiment, the UE can report CSI information according to the L sub-configurations included in the high-level configuration signaling and report the CSI information to the base station. The CSI information can be multiple sets of CSI information, with one set of CSI information associated with one sub-configuration. The content of the CSI information can be measured according to the corresponding sub-configuration.

[0070] In this embodiment, the UE is designed with high-performance UE capabilities. This allows the UE to support multiple sets of CSI information reporting, effectively saving base station energy consumption.

[0077] The UE capability may include a combination of one or more of the first UE capability, the second UE capability, the third UE capability, the fourth UE capability and the fifth UE capability.

[0081] In this embodiment, the fourth UE capability may indicate whether the UE supports configuring different types of parameters in different sub-configurations in a CSI report configuration. For example, the fourth UE capability may indicate whether the UE supports configuring first type parameters in sub-configuration 1 in a CSI report configuration, configuring third type parameters in sub-configuration 2, ..., configuring third type parameters and second type parameters in sub-configuration N, and configuring first type parameters and second type parameters in sub-configuration L.

[0090] In one embodiment, in response to the UE reporting support for the first UE capability and the second UE capability, or in response to the UE reporting support for the third UE capability, the L sub-configurations are one of the following:

[0095] Each of the L sub-configurations is configured with one type of parameter or two types of parameters, where the two types of parameters include a first type parameter and a second type parameter, or a second type parameter and a third type parameter.

[0096] In this embodiment, when the UE reports support for the first UE capability and the second UE capability, or when the UE reports support for the third UE capability, each sub-configuration of the L sub-configurations of a CSI report configuration may be configured with only first-type parameters, where the first-type parameters include rank restriction, codebook subset restriction, and port subset indication.

[0111] In this embodiment, in response to the UE reporting support for the first UE capability, the second UE capability and the fourth UE capability, the L sub-configurations may include: one or more sub-configurations configured with rank restriction, codebook subset restriction, and port subset indication, one or more sub-configurations configured with rank restriction, codebook subset restriction, and port subset indication and one of the following: one or more power offsets, one or more power deviation values, and one or more power offset indexes.

[0115] In one embodiment, in response to the UE reporting that it does not support the third UE capability or in response to the UE reporting that it does not support the fourth UE capability, or in response to the UE not reporting the third UE capability, or in response to the UE not reporting the fourth UE capability, the sub-configurations in the L sub-configurations are configured with parameters of the same type.

[0116] In this embodiment, in response to the UE reporting that it does not support the third UE capability or in response to the UE reporting that it does not support the fourth UE capability, or in response to the UE not reporting the third UE capability or the fourth UE capability, all sub-configurations in the L sub-configurations configure parameters of the same type, including any combination of first type parameters, second type parameters, and third type parameters.

[0117] In this embodiment, in response to the UE reporting that it does not support the third UE capability or in response to the UE reporting that it does not support the fourth UE capability, or in response to the UE not reporting the third UE capability or the fourth UE capability, all sub-configurations in the L sub-configurations configure parameters of the same type, including one of the first type parameters, the second type parameters, and the third type parameters.

[0118] In one embodiment, in response to the UE reporting support for a third UE capability or in response to the UE reporting support for a fourth UE capability, and / or the UE reporting support for a fifth UE capability, when N sub-configurations in the L sub-configurations are triggered by downlink control information or a MAC control element, the characteristics of the N sub-configurations are one of the following:

[0119] The parameters of the N sub-configurations are of the same type;

[0120] When the types of parameters configured by the N sub-configurations are different, the N sub-configurations cannot include both a sub-configuration configured with rank restriction, codebook subset restriction, and port subset indication and a sub-configuration configured with a resource list.

[0121] In this embodiment, when the types of parameters configured in the N sub-configurations are different, the N sub-configurations cannot simultaneously include a sub-configuration configured with parameters of the first type and a sub-configuration configured with parameters of the third type.

[0122] In one embodiment, when reporting CSI information, part of the CSI information in the CSI report is discarded according to the sub-configuration information and the CSI type information.

[0123] In this embodiment, discarding part of the CSI information in the CSI report based on the sub-configuration information and the CSI type information includes: determining a priority of the CSI types in the sub-configuration based on the sub-configuration information and the CSI type information, and discarding the CSI information based on the priority. Each set of CSI information may be divided into multiple parts, and the CSI type information may include part 1, sub-content 1 of part 2, sub-block 1 of sub-content 2 of part 2, and sub-block 2 of sub-content 2 of part 2.

[0124] In some embodiments, when reporting CSI information, the UE does not report all CSI information in the CSI report to the base station. For example, when the resources carrying the CSI information are insufficient to carry all the CSI information, it is necessary to discard some CSI information based on priority information and report the remaining CSI information to the base station. The priority information may include the priorities of the L sub-configurations and the priority of the CSI information type. The priority information may also be a priority determined based on the priorities of the L sub-configurations and the priority of the CSI information type. Sub-configurations and CSI information content with low priority are discarded first. Discarding stops when the remaining CSI information meets the resource requirements.

[0125] The priorities of the L sub-configurations can be configured by higher-layer signaling, predefined, or determined based on a sub-configuration index. High-layer signaling configures sub-configuration priority information, with each sub-configuration corresponding to a priority. The priorities among the L sub-configurations are predefined. The priorities of the L sub-configurations are represented by a sub-configuration index, where a larger sub-configuration index indicates a lower priority for the sub-configuration.

[0126] In some embodiments, the priority is represented by a numerical value, where the larger the numerical value, the lower the priority.

[0127] In one embodiment, the CSI information includes N sets of CSI information, where the N sets of CSI information are associated with N sub-configurations, where N is an integer greater than or equal to 1 and less than or equal to L. Each set of CSI information is divided into three parts: first-category CSI, second-category CSI, and third-category CSI;

[0128] The third type of CSI is divided into a third type of CSI sub-block 1 and a third type of CSI sub-block 2 according to odd sub-bands and even sub-bands.

[0129] In this embodiment, when a set of CSI information corresponds to one sub-configuration, each set of CSI information is divided into multiple parts: part 1 (i.e., the first type of CSI), sub-content 1 of part 2 (i.e., the second type of CSI), and sub-content 2 of part 2 (i.e., the third type of CSI). Among them, sub-content 2 of part 2 (i.e., the third type of CSI) is divided into sub-block 1 of sub-content 2 of part 2 (i.e., sub-block 1 of the third type of CSI) and sub-block 2 of sub-content 2 of part 2 (i.e., sub-block 2 of the third type of CSI) according to odd subbands and even subbands.

[0130] In this embodiment, when a set of CSI information corresponds to a sub-configuration, each set of CSI information is divided into multiple parts: part 1, sub-content 1 of part 2, sub-block 1 of sub-content 2 of part 2, and sub-block 2 of sub-content 2 of part 2. As shown in Figure 3, which is a schematic diagram of a CSI report provided by an embodiment, sub-configuration #1 corresponds to a set of CSI information, sub-configuration #2 corresponds to a set of CSI information, ..., and sub-configuration #N corresponds to a set of CSI information. The CSI information corresponding to sub-configuration #1 through sub-configuration #N all includes part 1, content 1 of part 2, sub-block 1 of sub-content 2 of part 2, and sub-block 2 of sub-content 2 of part 2. #1, #2, and #N represent sub-configuration indexes or sub-configuration priority values.

[0131] Part 1 (i.e., the first category of CSI) includes "CRI, RI, wideband CQI for transport block 1, and subband differential CQI for transport block 1." Some of the CSI information in this section may not be reported. For example, when a CSI report is configured to report only wideband CQI, the subband differential CQI for transport block 1 will not be reported. Therefore, when one or more of the information in "CRI, RI, wideband CQI for transport block 1, and subband differential CQI for transport block 1" is reported, this information is included in the first category of CSI.

[0132] Part 2, sub-content 1 (i.e., Category 2 CSI), includes "wideband CQI, layer indicator, and wideband PMI for transport block 2." Some CSI in this "wideband CQI, layer indicator, and wideband PMI for transport block 2" may not be reported. For example, when the rank in a CSI report is less than or equal to 4, the wideband CQI for transport block 2 will not be reported. Therefore, when one or more of the information in "wideband CQI, layer indicator, and wideband PMI for transport block 2" is reported, this information is included in Category 2 CSI.

[0133] Among them, sub-block 1 of sub-content 2 of part 2 (i.e., sub-block 1 of the third category of CSI) includes "sub-band differential CQI of the even sub-bands of transport block 2, sub-band PMI of the even sub-bands". Among them, some CSI of "sub-band differential CQI of the even sub-bands of transport block 2, sub-band PMI of the even sub-bands" may not be reported. For example, when the rank in a CSI report is less than or equal to 4, the sub-band differential CQI of the even sub-bands of transport block 2 will not be reported. Therefore, when one or more information of "sub-band differential CQI of the even sub-bands of transport block 2, sub-band PMI of the even sub-bands" is reported, this information is in sub-block 1 of the third category of CSI.

[0134] Among them, sub-block 2 of sub-content 2 of part 2 (i.e., sub-block 2 of the third type of CSI) includes "sub-band differential CQI of the odd sub-bands of transport block 2, sub-band PMI of the odd sub-bands". Among them, some CSI of "sub-band differential CQI of the odd sub-bands of transport block 2, sub-band PMI of the odd sub-bands" may not be reported. For example, when the rank in a CSI report is less than or equal to 4, the sub-band differential CQI of the odd sub-bands of transport block 2 will not be reported. Therefore, when one or more information of "sub-band differential CQI of the odd sub-bands of transport block 2, sub-band PMI of the odd sub-bands" is reported, this information is in sub-block 2 of the third type of CSI.

[0135] Among them, sub-content 2 of part 2 can be divided into two sub-blocks according to odd sub-bands and even sub-bands. Sub-block 1 of sub-content 2 of part 2 includes "sub-band differential CQI of even sub-bands of transmission block 2, sub-band PMI of even sub-bands", and sub-block 2 of sub-content 2 of part 2 includes "sub-band differential CQI of odd sub-bands of transmission block 2, sub-band PMI of odd sub-bands".

[0136] In one embodiment, a portion of the second type of content in the second type of sub-configuration is discarded, and the discarding order is one of the following:

[0137] Discard in the order of priority of the second-category sub-configurations, and discard in the order of priority of the second-category content in each sub-configuration;

[0138] Discard in the order of the second category content, and discard in the order of the priority of the sub-configuration in each content;

[0139] The second type of sub-configuration includes any combination of sub-configurations of different priorities, and the second type of content includes any combination of multi-part CSI types.

[0140] In some embodiments, the second-category sub-configurations are discarded in order of priority, and the second-category content in each sub-configuration is discarded in order of priority. The second-category sub-configurations and the second-category content may include the following:

[0141] The second category of sub-configurations includes all sub-configurations, and accordingly, the priority order of the second category of sub-configurations is sub-configuration #1>sub-configuration #2>…>sub-configuration #N; the second category of content includes sub-content 1 of part 2, sub-block 1 of sub-content 2 of part 2, and sub-block 2 of sub-content 2 of part 2, and accordingly, the priority order of the second category of content is: sub-content 1 of part 2>sub-block 1 of sub-content 2 of part 2>sub-block 2 of sub-content 2 of part 2. Discard according to the priority order of the second type of sub-configurations, and discard according to the priority order of the second type of content in each sub-configuration, then the discarding order is: {sub-block 2 of sub-content 2 of part 2 in sub-configuration #N-→sub-block 1 of sub-content 2 of part 2-→sub-content 1 of part 2}-→{sub-block 2 of sub-content 2 of part 2 in sub-configuration #N-1-→sub-block 1 of sub-content 2 of part 2-→sub-content 1 of part 2}-→…-→{sub-block 2 of sub-content 2 of part 2 in sub-configuration #2-→sub-block 1 of sub-content 2 of part 2-→sub-content 1 of part 2}-→{sub-block 2 of sub-content 2 of part 2 in sub-configuration #1-→sub-block 1 of sub-content 2 of part 2-→sub-content 1 of part 2}. The priority of the CSI types within a subconfiguration is determined based on the subconfiguration information and CSI type information. The priority is {subcontent 1 of Part 2 in subconfiguration #1 > subblock 1 of subcontent 2 of Part 2 > subblock 2 of subcontent 2 of Part 2} > ... > {subcontent 1 of Part 2 in subconfiguration #N > subblock 1 of subcontent 2 of Part 2 > subblock 2 of subcontent 2 of Part 2}. During discarding, if the remaining information meets resource requirements, discarding is stopped. The second category of subconfigurations includes subconfiguration #2, subconfiguration #3, ..., and subconfiguration #N. Accordingly, the priority order for the second category of subconfigurations is subconfiguration #2 > subconfiguration #3 > ... > subconfiguration #N. The second category of content includes Part 1, subcontent 1 of Part 2, subblock 1 of subcontent 2 of Part 2, and subblock 2 of subcontent 2 of Part 2. Accordingly, the priority order for the second category of content is Part 1 > subcontent 1 of Part 2 > subblock 1 of subcontent 2 of Part 2 > subblock 2 of subcontent 2 of Part 2. The discarding order is: {sub-block 2 of sub-content 2 of part 2 in sub-configuration #N → sub-block 1 of sub-content 2 of part 2 → sub-content 1 of part 2 → part 1} → {sub-block 2 of sub-content 2 of part 2 in sub-configuration #N-1 → sub-block 1 of sub-content 2 of part 2 → sub-content 1 of part 2 → part 1} → … → {sub-block 2 of sub-content 2 of part 2 in sub-configuration #2 → sub-block 1 of sub-content 2 of part 2 → sub-content 1 of part 2 → part 1}. If the remaining information during discarding satisfies the resource requirements, discarding stops.

[0142] The second category of sub-configurations includes sub-configuration #3, sub-configuration #4, ..., sub-configuration #N, and accordingly, the priority order of the second category of sub-configurations is sub-configuration #3>sub-configuration #4> ...>sub-configuration #N; the second category of content includes part 1, sub-content 1 of part 2, sub-block 1 of sub-content 2 of part 2, and sub-block 2 of sub-content 2 of part 2, and accordingly, the priority order of the second category of content is: part 1>sub-content 1 of part 2>sub-block 1 of sub-content 2 of part 2>sub-block 2 of sub-content 2 of part 2. The order of discarding is: {sub-block 2 of sub-content 2 of part 2 in sub-configuration #N → sub-block 1 of sub-content 2 of part 2 → sub-content 1 of part 2 → part 1} → {sub-block 2 of sub-content 2 of part 2 in sub-configuration #N-1 → sub-block 1 of sub-content 2 of part 2 → sub-content 1 of part 2 → part 1} → ... → {sub-block 2 of sub-content 2 of part 2 in sub-configuration #3 → sub-block 1 of sub-content 2 of part 2 → sub-content 1 of part 2 → part 1}. If the remaining information during discarding satisfies the resource requirements, discarding stops.

[0143] The second category of sub-configurations includes sub-configuration #2,..., sub-configuration #N, and accordingly, the priority order of the second category of sub-configurations is sub-configuration #2>sub-configuration #3>...>sub-configuration #N; the second category of content includes part 1, sub-content 1 of part 2, sub-block 1 of sub-content 2 of part 2, and sub-block 2 of sub-content 2 of part 2, and accordingly, the priority order of the second category of content is: part 1>sub-content 1 of part 2>sub-block 1 of sub-content 2 of part 2>sub-block 2 of sub-content 2 of part 2. The second category of content is discarded sequentially. Within each content, the priority order of the subconfigurations is as follows: {sub-block 2 of sub-content 2 of part 2 in subconfiguration #N → ... ---> sub-block 2 of sub-content 2 of part 2 in subconfiguration 2 → sub-block 1 of sub-content 2 of part 2 in subconfiguration #N → ... ---> sub-block 1 of sub-content 2 of part 2 in subconfiguration 2 → sub-content 1 of part 2 in subconfiguration #N → ... ---> sub-content 1 of part 2 in subconfiguration 2 → part 1 in subconfiguration #N → ... ---> part 1 in subconfiguration 2}. If the remaining information meets the resource requirements during discarding, discarding stops.

[0144] The second type of subconfiguration includes subconfiguration #2, subconfiguration #3, ..., and subconfiguration #N. Accordingly, the priority order of the second type of subconfiguration is subconfiguration #2 > subconfiguration #3 > ... > subconfiguration #N. The second type of content includes subblock 1 of subcontent 2 of part 2 and subblock 2 of subcontent 2 of part 2. Accordingly, the priority order of the second type of content is: subblock 1 of subcontent 2 of part 2 > subblock 2 of subcontent 2 of part 2. The discard order is: {subblock 2 of subcontent 2 of part 2 in subconfiguration #N - → subblock 1 of subcontent 2 of part 2} - → {subblock 2 of subcontent 2 of part 2 in subconfiguration #N-1 - → subblock 1 of subcontent 2 of part 2} - → ... - → {subblock 2 of subcontent 2 of part 2 in subconfiguration #2 - → subblock 1 of subcontent 2 of part 2}.

[0145] The second category of content does not include the first category of CSI.

[0146] The second category of content does not include the first category of CSI and the second category of CSI.

[0147] In one embodiment, a portion of the first type of content in the second type of sub-configuration is discarded, and the discarding order is one of the following:

[0148] Discard in the order of priority of the second-category sub-configurations. Within each sub-configuration, discard in the order of priority of the first-category content.

[0152] In some embodiments, the first and second categories of content together comprise all CSI information in a sub-configuration. In some embodiments, the first and second categories of content together comprise the second and third categories of CSI. In some embodiments, content in the first category is discarded in order of priority, with all sub-configurations within each category having the same priority. The first category of content may include Part 1 and sub-content 1 of Part 2, with Part 1 having a higher priority than sub-content 1 of Part 2. During discarding, if the remaining information meets resource requirements, discarding ceases.

[0161] The first category of sub-configurations includes at least sub-configuration #1. Alternatively, the first category of sub-configurations includes at least the sub-configuration with the highest priority. In some embodiments, the first category of sub-configurations are discarded in order of priority, and the fourth category of content within each sub-configuration is discarded in order of priority.

[0173] The following describes the channel state information reporting method by way of examples using different embodiments.

[0197] Example 1: The first UE capability indicates whether the UE supports configuring L sub-configurations in a CSI report configuration, and configuring rank restriction, codebook subset restriction, and port subset indication in the sub-configuration, or configuring a resource list in the sub-configuration. If the UE reports support for the first UE capability, it means that the UE supports configuring L sub-configurations in a CSI report configuration, and the sub-configuration can be configured with rank restriction, codebook subset restriction, and port subset indication, or the sub-configuration can be configured with a resource list.

[0209] Embodiment 11: The UE reports supported priority types, and in response to the UE capabilities, multiple sets of CSI reports can be reported based on the priority.

[0210] 2. Joint consideration

[0211] In the previous introduction, the parameter types that can be configured in sub-configuration are divided into three categories:

[0212] 1) First type parameters: rank restriction, codebook subset restriction, and port subset indication;

[0213] 2) The third type of parameter: resource list;

[0214] 3) Second type parameter: one of the following: one or more power offsets; one or more power deviation values; one or more power offset indexes.

[0215] In response to different UE capabilities, the sub-configuration requirements in the CSI reporting configuration are different.

[0216] In some embodiments, a sub-configuration in a CSI reporting configuration may configure only one parameter type, that is, the parameter type in all sub-configurations is the same.

[0217] In some embodiments, a CSI reporting configuration includes multiple sub-configurations, but each sub-configuration can only include one of the three types of parameters. For example, a CSI reporting configuration includes L sub-configurations, where L1 sub-configurations can be configured with the third type of parameters, and L2 sub-configurations can be configured with the second type of parameters, where L1 + L2 = L.

[0218] In some embodiments, in a sub-configuration in a CSI reporting configuration, the sub-configuration is configured with a first type parameter, and the sub-configuration and the third type parameter configured in the sub-configuration cannot be in the same CSI reporting configuration.

[0219] In some embodiments, a CSI reporting configuration includes multiple sub-configurations, and the parameter type of each sub-configuration includes at least one of the above three parameter types. For example, a CSI reporting configuration includes L sub-configurations, where L1 sub-configurations are configured with the third type of parameters, and L2 sub-configurations are configured with the second type of parameters and the third type of parameters, where L1+L2=L.

[0220] In some embodiments, a CSI reporting configuration includes multiple sub-configurations, each of which is configured with first-type parameters or third-type parameters, as well as second-type parameters. All sub-configurations have the same parameter type. For example, there may be L sub-configurations, each of which is configured with first-type parameters and second-type parameters. In another example, there may be L sub-configurations, each of which is configured with second-type parameters and third-type parameters.

[0221] In some embodiments, for aperiodic or semi-persistent CSI reporting, a CSI reporting configuration includes L sub-configurations, each of which is configured with at least one of the three types of parameters. When N sub-configurations are triggered within the L sub-configurations using DCI or MAC CE, the N sub-configurations cannot simultaneously include a sub-configuration configured with the first type of parameters and a sub-configuration configured with the third type of parameters. In other embodiments, the N sub-configurations include parameters of the same type.

[0222] In some embodiments, when the number of power offset values ​​configured for each CSI-RS resource in a resource set associated with a CSI report configuration (CSI-ReportConfig) is greater than 1, at least a second type of parameter is configured in a sub-configuration in the CSI report configuration.

[0223] In some embodiments, in response to the UE indicating support for configuring multiple types of parameters in a sub-configuration of a CSI report, a CSI report configuration includes L sub-configuration configurations, each sub-configuration configures second-type parameters and / or third-type parameters, the number of parameters in the second-type parameters is equal to the number of CSI-RS resources in a resource set associated with the CSI report, and the parameters in the second-type parameters are one of the following: one or more power offsets, one or more power deviation values, and one or more power offset indexes.

[0224] In some embodiments, a CSI report configuration includes L sub-configuration configurations, wherein one or more sub-configuration configurations are configured with third-type parameters, the number of resources associated with each sub-configuration is the same, and the i-th CSI-RS resources associated with different sub-configurations are quasi-co-located with respect to "QCL type D". For example, a CSI report configuration has two sub-configurations, sub-configuration #1 is associated with {CSI-RS resource #1, CSI-RS resource #2}, and sub-configuration #2 is associated with {CSI-RS resource #3, CSI-RS resource #4}. The first CSI-RS resource associated with sub-configuration #1 is CSI-RS resource #1, and the first CSI-RS resource associated with sub-configuration #2 is CSI-RS resource #3. Therefore, CSI-RS resource #1 and CSI-RS resource #3 are quasi-co-located with respect to "QCL type D", and CSI-RS resource #2 and CSI-RS resource #4 are quasi-co-located with respect to "QCL type D".

[0225] In some embodiments, a CSI report configuration includes L sub-configuration configurations, wherein one or more sub-configurations are configured with third-type parameters, the number of resources associated with each sub-configuration is the same, and the i-th CSI-RS resources associated with different sub-configurations are quasi-co-located. For example, a CSI report configuration has two sub-configurations, sub-configuration #1 is associated with {CSI-RS resource #1, CSI-RS resource #2}, and sub-configuration #2 is associated with {CSI-RS resource #3, CSI-RS resource #4}. The first CSI-RS resource associated with sub-configuration #1 is CSI-RS resource #1, and the first CSI-RS resource associated with sub-configuration #2 is CSI-RS resource #3. Therefore, CSI-RS resource #1 is quasi-co-located with CSI-RS resource #3, and CSI-RS resource #2 is quasi-co-located with CSI-RS resource #4.

[0226] In some embodiments, a CSI report configuration includes L sub-configuration configurations, wherein one or more sub-configuration configurations are configured with third type parameters, in response to the UE reporting multiple sets of CSI reports that support overhead savings, the number of resources associated with each sub-configuration is the same, and the i-th CSI-RS resources associated with different sub-configurations are quasi-co-located.

[0227] In some embodiments, a CSI report configuration includes L sub-configuration configurations, wherein one or more sub-configuration configurations are configured with third type parameters, in response to the UE reporting multiple sets of CSI reports that support overhead savings, the number of resources associated with each sub-configuration is the same, and the i-th CSI-RS resources associated with different sub-configurations are quasi-co-located with respect to "QCL typeD".

[0228] In some embodiments, a CSI report configuration includes L sub-configuration configurations, wherein one or more sub-configuration configurations are configured with third type parameters. In response to the UE reporting multiple sets of CSI reports supporting common CRI, the number of resources associated with each sub-configuration is the same, and the i-th CSI-RS resources associated with different sub-configurations are quasi-co-located.

[0229] In some embodiments, a CSI report configuration includes L sub-configuration configurations, wherein one or more sub-configuration configurations are configured with third type parameters. In response to the UE reporting multiple sets of CSI reports supporting common CRI, the number of resources associated with each sub-configuration is the same, and the i-th CSI-RS resources associated with different sub-configurations are quasi-co-located with respect to "QCL typeD".

[0230] 3. CSI information discarding rules / priority rules

[0231] In some embodiments, the CSI report is divided into two parts for transmission. Part 1 includes "CRI, RI, wideband CQI of transport block 1, subband differential CQI of transport block 1", and is arranged in this order. If the above contents are not reported in the CSI report, the unreported parts are skipped. Part 2 is divided into two sub-contents. Sub-content 1 includes "wideband CQI of transport block 2, layer indication, wideband PMI", and is arranged in this order. If the above contents are not reported in the CSI report, the unreported parts are skipped. Sub-content 2 of Part 2 includes "subband differential CQI of even subbands of transport block 2, subband PMI of even subbands, subband differential CQI of odd subbands of transport block 2, subband PMI of odd subbands", and is arranged in this order. If the above contents are not reported in the CSI report, the unreported parts are skipped.

[0232] Under certain conditions, for example, if the PUSCH resources are insufficient to carry all the bits in the CSI report, some of the CSI report content will be discarded, meaning it will not be transmitted. The order of discarding is determined by priority, with discarding being done in ascending order of priority.

[0233] Example 1: In some embodiments, part 1 of all sub-configurations will not be discarded, and the remaining content will be discarded in the order of sub-configurations. In each sub-configuration, the priority order is: sub-content 1 of part 2 > sub-block 1 of sub-content 2 of part 2 > sub-block 2 of sub-content 2 of part 2, and the discard order is:

[0234] {sub-configuration#N: sub-block 2 of sub-content 2 of part 2 ----> sub-block 1 of sub-content 2 of part 2 ----> sub-content 1 of part 2}---->{sub-configuration#N-1: sub-block 2 of sub-content 2 of part 2 ----> sub-block 1 of sub-content 2 of part 2 ----> sub-content 1 of part 2}---->...--->{sub-configuration#1: sub-block 2 of sub-content 2 of part 2 ----> sub-block 1 of sub-content 2 of part 2 ----> sub-content 1 of part 2}.

[0235] FIG4a is a schematic diagram of a first priority order of various components of CSI information in a CSI report provided by an embodiment. Taking N=3 as an example, the priority values ​​of various components in each sub-configuration are shown in FIG4a , and the corresponding discarding order is shown in FIG4b . FIG4b is a schematic diagram of a discarding order of various components of CSI information in a CSI report provided by an embodiment. The discarding order is:

[0236] {sub-configuration#3: sub-block 2 of sub-content 2 of part 2 ----> sub-block 1 of sub-content 2 of part 2 ----> sub-content 1 of part 2}---->{sub-configuration#2: sub-block 2 of sub-content 2 of part 2 ----> sub-block 1 of sub-content 2 of part 2 ----> sub-content 1 of part 2}---->...--->{sub-configuration#1: sub-block 2 of sub-content 2 of part 2 ----> sub-block 1 of sub-content 2 of part 2 ----> sub-content 1 of part 2}.

[0237] In some embodiments, the priority between sub-configurations is determined based on one of the following: higher-layer signaling configuration, pre-defined information, or a sub-configuration index value. For example, higher-layer signaling configuration includes sub-configuration priority information, with each sub-configuration corresponding to a priority; for example, the priority between sub-configurations is pre-defined; for example, the priority of a sub-configuration is determined by an index value, where a higher index value indicates a lower priority.

[0238] Example 2: The content of the sub-configuration with the highest priority will not be discarded, and the remaining content will be discarded in the order of sub-configuration priority. In each sub-configuration, the priority order is: part 1 > sub-content 1 of part 2 > sub-block 1 of sub-content 2 of part 2 > sub-block 2 of sub-content 2 of part 2. For example, the discard order is:

[0239] {sub-configuration#N: sub-block 2 of sub-content 2 of part 2 ----> sub-block 1 of sub-content 2 of part 2 ----> sub-content 1 of part 2---> part 1}---->{sub-configuration#N-1: sub-block 2 of sub-content 2 of part 2 ----> sub-block 1 of sub-content 2 of part 2 ----> sub-content 1 of part 2---> part 1}---->...--->{sub-configuration#2: sub-block 2 of sub-content 2 of part 2 ----> sub-block 1 of sub-content 2 of part 2 ----> sub-content 1 of part 2---> part 1}.

[0240] FIG5 is a schematic diagram of a second priority order of various parts of CSI information in a CSI report provided by an embodiment. As shown in FIG5 , taking N=3 as an example, the corresponding discarding order is:

[0241] {sub-configuration#3:sub-block 2 of sub-content 2 of part 2---->sub-block 1 of sub-content 2 of part 2---->sub-content 1 of part 2--->part 1}---->{sub-configuration#2:sub-block 2 of sub-content 2 of part 2---->sub-block 1 of sub-content 2 of part 2---->sub-content 1 of part 2--->part 1}.

[0242] Example 3: The first category of content in the first category of sub-configuration will not be discarded, and the remaining content will be discarded in the order of sub-configuration. In each sub-configuration, the priority is: sub-content 1 of part 2 > sub-block 1 of sub-content 2 of part 2 > sub-block 2 of sub-content 2 of part 2.

[0243] The first type of sub-configuration is one of the following: a sub-configuration indicated by higher-layer signaling, a predefined sub-configuration, or the first N sub-configurations with the highest priority, where N is a positive integer less than 3.

[0244] The first category of content is at least one of the following: part 1, sub-content 1 of part 2.

[0245] For example, if the first sub-configuration is sub-configuration #1 and sub-configuration #2, and the first content is sub-content 1 of part 1 and part 2, the discard order is:

[0246] {sub-configuration#N: sub-block 2 of sub-content 2 of part 2 ----> sub-block 1 of sub-content 2 of part 2 ----> sub-content 1 of part 2---> part 1}---->{sub-configuration#N-1: sub-block 2 of sub-content 2 of part 2 ----> sub-block 1 of sub-content 2 of part 2 ----> sub-content 1 of part 2---> part 1}---->...--->{sub-configuration#3: sub-block 2 of sub-content 2 of part 2 ----> sub-block 1 of sub-content 2 of part 2 ----> sub-content 1 of part 2---> part 1--->sub-configuration#2: sub-block 2 of sub-content 2 of part 2 ----> sub-block 1 of sub-content 2 of part 2--->sub-configuration#1: sub-block 2 of sub-content 2 of part 2 ----> sub-block 1 of sub-content 2 of part 2}.

[0248] {sub-configuration#3:sub-block 2 of sub-content 2 of part 2---->sub-block 1 of sub-content 2 of part 2---->sub-content 1 of part 2--->part 1--->sub-configuration#2:sub-block 2 of sub-content 2 of part 2---->sub-block 1 of sub-content 2 of part 2--->sub-configuration#1:sub-block 2 of sub-content 2 of part 2---->sub-block 1 of sub-content 2 of part 2}.

[0249] Example 4: The second category of content of the second category of sub-configuration is discarded first, and is discarded in the order of the sub-configuration. In each sub-configuration, the priority is: sub-block 1 of sub-content 2 of part 2 > sub-block 2 of sub-content 2 of part 2. Then the first category of content of the second category of sub-configuration is discarded, and is discarded in the order of the sub-configuration; in some embodiments, the fourth category of content of the first category of sub-configuration can also be discarded; in some embodiments, the fourth category of content of the first category of sub-configuration cannot be discarded.

[0250] In some embodiments, the second category of content includes sub-block 1 of sub-content 2 of part 2, and sub-block 2 of sub-content 2 of part 2; the first category of content includes part 1; and the fourth category of content includes sub-block 1 of sub-content 2 of part 2, and sub-block 2 of sub-content 2 of part 2.

[0251] The second type of sub-configuration is a sub-configuration other than the first type of sub-configuration.

[0252] In some embodiments, part 1 is discarded together, that is, the priority of part 1 of the second type of sub-configuration is the same.

[0253] In some embodiments, the sub-content 1 of part 2 is discarded together, that is, the sub-content 1 of part 2 of the second type of sub-configuration has the same priority.

[0254] FIG7a is a schematic diagram of a fourth priority order of various components of CSI information in a CSI report provided by an embodiment. Taking N=3 as an example, the priorities of various components in each sub-configuration are shown in FIG7a , and the corresponding discarding order is shown in FIG7b . FIG7b is a schematic diagram of another discarding order of various components of CSI information in a CSI report provided by an embodiment. The discarding order is:

[0255] {sub-configuration#3:sub-block 2 of sub-content 2 of part 2---->sub-block 1 of sub-content 2 of part 2---->sub-configuration#2:sub-block 2 of sub-content 2 of part 2---->sub-block 1 of sub-content 2 of part 2--->sub-configuration#3:sub-content 1 of part 2---->sub-configuration#2:sub-content 1 of part 2---->sub-configuration#3:part 1---->sub-configuration#2:part 1---->sub-configuration#1:sub-block 2 of sub-content 2 of part 2---->sub-block 1 of sub-content 2 of part 2}.

[0256] FIG8 is a schematic diagram of a fifth priority order of various parts of CSI information in a CSI report provided by an embodiment. As shown in FIG8 , taking N=3 as an example, the corresponding discarding order is:

[0257] {sub-configuration#3: sub-block 2 of sub-content 2 of part 2 ----> sub-block 1 of sub-content 2 of part 2 ----> sub-configuration#2: sub-block 2 of sub-content 2 of part 2 ----> sub-block 1 of sub-content 2 of part 2 ----> sub-configuration#2 and sub-configuration#3: sub-content 1 of part 2 ----> part 1 ----> sub-configuration#1: sub-block 2 of sub-content 2 of part 2 ----> sub-block 1 of sub-content 2 of part 2}.

[0258] For example: UE discards part of the CSI information according to the priority information, including: discarding according to the priority order of the second type of sub-configuration, and discarding according to the priority order of the second type of content in each sub-configuration; b. discarding according to the order of the first type of content, and discarding according to the priority order of the sub-configuration in each type of content. The second content includes sub-block 1 of sub-content 2 of part 2, and sub-block 2 of sub-content 2 of part 2; the first content includes part 1 and sub-content 1 of part 2; the second type of sub-configuration includes sub-configuration #2...#N, then the priority order is shown in Figure 9, which is a schematic diagram of the sixth priority order of each part of the CSI information in the CSI report provided by an embodiment. As shown in Figure 9, taking N=3 as an example, the corresponding discarding order is:

[0259] {sub-configuration#3:sub-block 2 of sub-content 2 of part 2---->sub-block 1 of sub-content 2 of part 2---->sub-configuration#2:sub-block 2 of sub-content 2 of part 2---->sub-block 1 of sub-content 2 of part 2---->sub-configuration#2:sub-content 1 of part 2---->sub-configuration#2:sub-content 1 of part 2---->sub-configuration#3:part 1---->sub-configuration#2:part 1}.

[0260] In some embodiments, the third category of content in the first sub-configuration will not be discarded, which also means that the third category of content in the first sub-configuration does not need to be prioritized.

[0261] Omit can also be called deletion, omission, etc.

[0262] In some embodiments, only CSI types of sub-configurations that can be omitted need to be prioritized.

[0263] In some embodiments, the second category of content in the second sub-configuration may be discarded first. When discarding the second category of content in the second sub-configuration, the discarding process is performed according to the first order. During this process, if the remaining CSI information meets the bitrate or resource requirements, the discarding process stops. If all the second category of content in the second sub-configuration has been discarded and the requirements are still not met, the fourth category of content in the first sub-configuration is discarded. When discarding the fourth category of content in the first sub-configuration, the discarding process is performed according to the second order. During this process, if the remaining CSI information meets the bitrate or resource requirements, the discarding process stops.

[0264] The first type of sub-configuration includes at least sub-configuration 1.

[0265] The second type of sub-configuration includes sub-configurations other than the first type of sub-configuration.

[0266] The second category of content includes at least sub-block 1 of the third category of CSI and sub-block 2 of the third category of CSI.

[0267] The fourth category of content includes at least sub-block 1 of the third category of CSI or sub-block 2 of the third category of CSI.

[0268] In some embodiments, the second category of content of the second category sub-configuration may be discarded first. When discarding the second category of content of the second category sub-configuration, the discarding is performed in the first order. During this process, if the remaining CSI information meets the code rate or resource requirements, the discarding is stopped. If the second category of content of the second category sub-configuration is discarded and still does not meet the requirements, the fourth category of content of the first category sub-configuration is discarded. When discarding the fourth category of content of the first category sub-configuration, the discarding is performed in the second order. During this process, if the remaining CSI information meets the code rate or resource requirements, the discarding is stopped. If the fourth category of content of the first category sub-configuration is discarded and still does not meet the requirements, the first category of content of the second category sub-configuration is discarded. When discarding the first category of content of the second category sub-configuration, the discarding is performed in the third order. During this process, if the remaining CSI information meets the code rate or resource requirements, the discarding is stopped.

[0269] The fourth category of content includes at least the second category of CSI.

[0270] The first / second / third order can be one of the following:

[0271] Discard in the order of priority of the sub-configurations, and in each sub-configuration, discard in the order of priority of the content;

[0272] Discard in order of priority of sub-configurations, and the content of each sub-configuration has the same priority;

[0273] Discard in order of content priority, and in each content, discard in order of sub-configuration priority;

[0274] Discard in order of content priority, all sub-configurations of each content have the same priority;

[0275] Discard the contents of the child configuration.

[0276] In some embodiments, the second category of content in the second sub-configuration may be discarded first. When discarding the second category of content in the second sub-configuration, the discarding process is performed according to the first order. During this process, if the remaining CSI information meets the bitrate or resource requirements, the discarding process stops. If the second category of content in the second sub-configuration has been discarded and the requirements are still not met, the first category of content in the third sub-configuration is discarded. When discarding the first category of content in the third sub-configuration, the discarding process is performed according to the second order. During this process, if the remaining CSI information meets the bitrate or resource requirements, the discarding process stops.

[0277] The second type of sub-configuration may include all sub-configurations.

[0278] For example, the second type of subconfiguration includes all subconfigurations; the third type of subconfiguration includes subconfigurations except subconfiguration 1; the second type of content includes subblock 1 of the third type of CSI and subblock 2 of the third type of CSI; the first type of content includes the first type of CSI and the second type of CSI; the first order is to discard according to the priority order of the subconfiguration, and discard according to the priority order of the content in each subconfiguration. The second order is to discard according to the priority order of the content, and discard according to the priority order of the subconfiguration in each content. The corresponding discard order is:

[0279] {Subconfiguration N: subblock 2 of the third category CSI---> subblock 1 of the third category CSI}--->{Subconfiguration N-1: subblock 2 of the third category CSI---> subblock 1 of the third category CSI}--->...--->{Subconfiguration 1: subblock 2 of the third category CSI---> subblock 1 of the third category CSI}--->{Subconfiguration N: second category CSI---> Subconfiguration N-1: second category CSI--->... Subconfiguration 2: second category CSI}--->{Subconfiguration N: first category CSI---> Subconfiguration N-1: first category CSI--->... Subconfiguration 2: first category CSI}.

[0280] In some embodiments, the priority is determined based on sub-configuration information and CSI type information. The sub-configuration information includes one of the following: a sub-configuration priority and a sub-configuration index. The CSI type information includes a CSI type priority. The CSI type can be a first-class CSI, a second-class CSI, a sub-block 1 of a third-class CSI, or a sub-block 2 greater than a third-class CSI.

[0281] The sub-configuration priority can be determined based on one of the following: high-level configuration signaling, definition information, and index.

[0282] In some embodiments, the larger the index value of the sub-configuration, the lower its priority. In some embodiments, the priority of the CSI type is first type CSI > second type CSI > sub-block 1 of third type CSI > greater than sub-block 2 of third type CSI.

[0283] In some embodiments, subblock 1 of the third type of CSI includes odd subbands of the third type of CSI. Subblock 2 of the third type of CSI includes even subbands of the third type of CSI. In some embodiments, subblock 1 of the third type of CSI includes even subbands of the third type of CSI. Subblock 2 of the third type of CSI includes odd subbands of the third type of CSI.

[0286] In some embodiments, the priority of a low priority CSI type in a low priority sub-configuration is less than the priority of a higher priority CSI type in the low priority sub-configuration.

[0287] In some embodiments, the priority of a lower priority CSI type in a low priority sub-configuration is less than the priority of a same priority CSI type in a high priority sub-configuration.

[0288] In some embodiments, the priority of a higher priority CSI type in a low priority sub-configuration is less than the priority of a low priority CSI type in a high priority sub-configuration.

[0291] In some embodiments, the priority of a CSI type in a high-priority sub-configuration is greater than the priority of a CSI type in a low-priority sub-configuration.

[0292] Low priority / high priority here may mean lower priority / higher priority.

[0294] In some embodiments, the priority of the second category of content in the second category of sub-configuration is lower than the priority of the first category of content in the third category of sub-configuration.
