[0068] Compared with the fourth generation of mobile communications, the fifth generation of mobile communications New Radio (NR) system needs to support high frequency bands, large bandwidth, and large-scale antenna technology. While improving system performance, the power consumption of 5G base stations is increased to 2 to 3 times that of 4G base stations. Energy consumption is the main indicator of the operating expenses (OPEX) of operators. According to operator data, the operating cost of energy consumption in mobile networks accounts for ~23% of the total operating cost, becoming a heavy burden for the widespread deployment of 5G networks. The energy consumption problem also limits its application in vertical industries and the large-scale popularization of 5G terminals.

[0069] According to the measured results, most of the energy consumption of the base station comes from the wireless access network, especially the large-scale antenna array (Active Antenna Unit, AAU) part. The AAU at least includes the radio frequency and antenna unit. The base station adjusts the energy consumption of the base station airspace network by turning the TXRU off and on. Furthermore, when the TXRU is turned off and on, the corresponding CSI measurement and reporting need to adapt to the turning on and off of the TXRU.

[0070] There is no standardized solution for the measurement and equipment of CSI when the TXRU is turned off and on. In the NR system Release 17 (Rel-17) protocol, the measurement and equipment of CSI are closely related to the CSI framework. The CSI framework includes two parts: resource configuration and reporting configuration.

[0071] Resource configuration, used to configure the high-level signaling CSI-Resou rceConfig IE corresponding to the CSI reference signal (Resource Setting and CSI-ResourceConfig have the same meaning in this article), IE stands for Information Element. Each CSI-ResourceConfig contains at least one NZP-CSI-RS-SSB and / or at least one NZP-CSI-RS-Resou rceSet. Each NZP-CSI-RS-ResourceSet contains at least one NZP-CSI-RS-Resource. Among them, NZP means non-zero power (Non Zero Power), CSI-RS means channel state information reference signal (Channel State Information Reference Signa l), and SSB means synchronization signal block (Synchronization Signal Block).

[0072] The reporting configuration is mainly completed through the Radio Resource Control (R RC) layer signaling CSI-ReportConfig IE (Reporting Setting and CSI-ReportConfig have the same meaning in this article), which is used to configure the CSI reporting behavior. Each CSI-ReportConfig is associated with one or more CSI-ResourceConfigs, indicating the resource configuration for channel measurement and / or interference measurement.

[0073] In addition, each CSI-ReportConfig also includes:

[0074] CSI reporting time domain behavior, including periodic, semi-persistent on PUCCH, semi-persistent on PUSCH, aperiodic CSI reporting types and corresponding reporting period, offset and other reporting resource configurations; PUSCH stands for Physical Uplink Shared Channel.

[0075] CSI reports related frequency domain behaviors, such as the frequency domain granularity of the Channel Quality Indicator (CQI) and Precoder Matrix Indicator (PMI), including broadband and sub-band.

[0076] Measurement limit configuration, including limits for channel measurements and limits for interference measurements;

[0077] The CSI-related indicators reported by the UE include CQI, PMI, CSI-RS Resource Indicator (CRI), Synchronization Signals Block Resource Indicator (SSBRI), Layer Indicator (LI), Rank Indicator (RI), Layer 1 Reference Signal Receiving Power (L1-RS RP) or Layer 1 Signal to Interference plus Noise Ratio (L1-SINR) and other related configuration parameters.

[0078] In addition, each CSI-ReportConfig also includes a codebook configuration, including a Type I, Type II or enhanced Type II codebook and a codebook restriction subset.

[0079] Furthermore, a DCI CSI request signaling activates a triggering state, and a triggering state can be associated with multiple reportconfigs (AP-CSI) and one reportconfig (SP-CSI). DCI stands for Downlink Control Information, AP-CSI stands for Aperiodic CSI, and SP-CSI stands for Semi-persistent CSI.

[0080] Figure 1 is a flowchart of non-periodic CSI measurement and reporting provided in an embodiment of the present application, such as Figure 1 As shown, the aperiodic CSI (AP-CSI) report is only transmitted on the physical uplink shared channel (Physical Uplink Shared Channel, PUSCH).

[0081] Figure 2 is a flow chart of semi-continuous CSI measurement and reporting provided in an embodiment of the present application, such as Figure 2As shown, semi-persistent CSI (SP-CSI) is reported on PUSCH and Physical Uplink Control Channel (PUCCH), and the figure mainly shows the transmission on PUSCH.

[0082] The following fields can be included in the CSI reporting configuration:

[0083] Report Configuration Identifier (reportConfigId) field: indicates the identifier of the current CSI reporting configuration;

[0084] Channel measurement resources (resourcesForChannelMeasurement) field: indicates the non-zero power CSI reference signal used for channel measurement;

[0085] CSI interference measurement resources (csi-IM-ResourcesForInterference) field: indicates the CSI interference measurement resource report identifier used for interference measurement.

[0086] NZP-CSI-RS interference measurement resources (nzp-CSI-RS-ResourcesForInterference) field: indicates the NZP-CSI-RS resource reporting identifier used for interference measurement.

[0087] Resource configuration type (reportConfigType) field: indicates the type of report configuration, including periodic, aperiodic, and semi-continuous.

[0088] Report Quantity field: indicates the quantity that the CSI report can contain.

[0089] The report frequency band configuration (reportFreqConfiguration) indicates the frequency band for CSI report measurement.

[0090] In the CSI reporting mechanism, when different TXRUs are turned off and on, only the CSI report corresponding to one antenna unit can be reported at the same time, which cannot reflect the change of the antenna pattern. While reducing the network energy consumption, it also reduces the system performance of the network.

[0091] Furthermore, in the discussion of network energy-saving technology, the CSI sub-configuration report mechanism is supported, that is, a CSI reporting configuration contains multiple CSI reporting sub-configurations, where each CSI reporting sub-configuration corresponds to a spatial adaptation pattern (antenna pattern). The antenna port is associated with the TxRU through port virtualization, so the shutdown of the TxRU may not only cause changes in the transmit power, but also cause the shutdown of the antenna port. Different shutdown methods of spatial elements will form different spatial adaptation patterns / patterns (spatial adaptation pattern or spatial element adaptation pattern).

[0092] For a CSI reporting configuration with L subconfigurations, it is supported that the UE is able to report N CSI frames in one reporting instance, where the N CSI frames are associated with N CSI reporting subconfigurations from L (where 1≤N≤L), and each CSI frame corresponds to one CSI reporting subconfiguration.

[0093] However, there is no clear solution on how to indicate N CSI reporting subconfigurations from L CSI reporting subconfigurations. Therefore, the embodiments of the present application provide a method, device and storage medium for sending and receiving CSI reports, which trigger part or all of the CSI reporting subconfigurations configured on the network side through the first information, support CSI reporting configurations with multiple subconfigurations, so that the terminal can report multiple CSI frames in one CSI reporting instance, each CSI frame corresponds to a CSI subconfiguration, and a CSI subconfiguration corresponds to an antenna pattern, so that when different TXRUs are turned off and on, the changes in channel states caused by changes in antenna patterns are well reflected, better link adaptation and better transmission performance are achieved, and a balance between network energy consumption and network performance is achieved.

[0094] In the embodiments of the present application, the term "and / or" describes the association relationship of the associated objects, indicating that three relationships may exist. For example, A and / or B may represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the associated objects before and after are in an "or" relationship.

[0095] In the embodiments of the present application, the term "plurality" refers to two or more than two, and other quantifiers are similar.

[0096] The technical solution provided in the embodiment of the present application can be applicable to a variety of systems, especially 5G system, 5G Advanced system, 6G system and their evolution system.

The wireless terminal device can communicate with one or more core networks (CN) via a radio access network (RAN). The wireless terminal device can be a mobile terminal device, such as a mobile phone (or a "cellular" phone) and a computer with a mobile terminal device. For example, it can be a portable, pocket-sized, handheld, computer-built-in or vehicle-mounted mobile device that exchanges language and / or data with a wireless access network. For example, personal communication service (PCS) phones, cordless phones, session initiation protocol (SIP) phones, wireless local loop (WLL) stations, personal digital assistants (PDA) and other devices.

In some network structures, the network device may include a centralized unit (CU) node and a distributed unit (DU) node, and the centralized unit and the distributed unit may also be arranged geographically separately.

[0099] Network devices and terminal devices can each use one or more antennas for multiple-input multiple-output (MIMO) transmission.

Depending on the form and number of antenna combinations, MIMO transmission can be 2D-MIMO, 3D-MIMO, FD-MIMO or massive-MIMO, or it can be diversity transmission, precoded transmission or beamforming transmission, etc.

[0100] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0101] Figure 3 is a flow chart of a method for sending a CSI report provided in an embodiment of the present application, such as Figure 3 As shown, the execution subject of the method is a terminal, and the method at least includes the following steps:

[0102] Step 301: receiving configuration information and first information sent by a network device;

[0103] Step 302: Send a CSI report to the network device based on the configuration information and the first information.

[0104] Specifically, the terminal receives configuration information and first information sent by the network device. The configuration information includes at least CSI reporting sub-configuration, trigger state configuration, and the association relationship between the trigger state configuration and the CSI reporting sub-configuration. The first information is used to trigger part or all of the CSI reporting sub-configuration. The first information is, for example, trigger state activation / trigger information.

[0105] For example, the network side configures L CSI reporting sub-configurations, and the first information is used to trigger N CSI reporting sub-configurations among the L CSI sub-configurations, where N is less than or equal to L, and both N and L are integers greater than 0.

[0106] The configuration information at least includes:

[0107] CSI reporting subconfiguration. One CSI reporting subconfiguration corresponds to one adaptive spatial pattern (antenna pattern). Optionally, the CSI reporting subconfiguration includes at least one of the following: a spatial adaptation indication for supporting CSI reporting enhancement based on spatial adaptation; antenna array size parameters n1-n2, used to determine a subset of the MIMO codebook; antenna panel number Ng for helping to determine the multi-panel MIMO codebook; activated antenna port index corresponding to the spatial adaptive pattern; power offset of CSI-RS relative to SSB based on the spatial adaptive pattern; antenna array size information, including the number of antenna array horizontal dimensions N1 and the number of antenna array vertical dimensions N2 for single-panel, and the number of antenna array horizontal dimensions N1, the number of antenna array vertical dimensions N2, and the number of antenna panels Ng for multi-panel; port subset indication; index of PMI or precoding matrix; rank restriction.

[0108] The associated configuration of the CSI reporting sub-configuration includes a trigger state configuration associated with the CSI reporting sub-configuration, such as trigger state. In the associated configuration of the CSI reporting sub-configuration, the association relationship between the CSI reporting sub-configuration and the trigger state configuration is indicated.

[0109] Optionally, the configuration information also includes at least one of the following:

[0110] CSI reporting configuration. Optionally, the CSI reporting configuration includes at least one of the following: CSI reporting configuration ID, resource configuration for channel measurement, resource configuration for interference measurement, reporting configuration type, reporting quality, reporting frequency domain configuration, channel measurement time domain restriction, interference measurement time domain restriction, codebook configuration, group-based beam reporting, CQI table, subband size, non-PMI port indication, PUSCH-based semi-persistent CSI reporting parameters, non-periodic CSI reporting parameters, reporting quality, shared CMR configuration (Sharing of Channel Measurement Resources), CSI reporting mode configuration, single TRP CSI mode 1 number configuration, CSI reporting period and offset, PUCCH resources for CSI reporting, and 8-rank port index parameters.

[0111] The associated configuration of the CSI reporting configuration includes the trigger state configuration associated with the CSI reporting configuration, such as triggerstate, which includes the association relationship between the CSI reporting configuration and the trigger state, such as one trigger state is associated with at least one CSI reporting configuration, and one CSI reporting configuration is associated with one trigger state, etc. For details, please refer to Table 1:

[0112] Table 1: CSI reporting configuration related configuration

[0113]

[0114] The terminal performs CSI reporting based on the first information and the configuration information, and sends a CSI report to the network device. Optionally, the CSI report includes an antenna pattern in a CSI reporting sub-configuration triggered by the first information.

[0115] The CSI report sending method provided in the embodiment of the present application triggers part or all of the CSI reporting sub-configurations configured on the network side through the first information, supports a CSI reporting configuration with multiple sub-configurations, so that the terminal can report multiple CSI frames in one CSI reporting instance, each CSI frame corresponds to a CSI sub-configuration, and a CSI sub-configuration corresponds to an antenna pattern. Therefore, when different TXRUs are turned off and on, the changes in the channel state caused by the changes in the antenna pattern are well reflected, thereby achieving better link adaptation and better transmission performance, and achieving a balance between network energy consumption and network performance.

[0116] Optionally, the trigger state configuration includes a first trigger state configuration and a second trigger state configuration; the first trigger state configuration is associated with the full set of CSI reporting sub-configurations supported by the network; and the second trigger state configuration is associated with a subset of the full set of CSI reporting sub-configurations supported by the network.

[0117] Specifically, the trigger state configuration can be divided into two categories: a first trigger state configuration and a second trigger state configuration.

[0118] The first trigger state configuration may be a dedicated trigger state configuration, such as Dedicated triggerstate, trigger state=1, etc. The corresponding network supports the full set of CSI reporting sub-configurations. For example, the network configures L CSI reporting sub-configurations, and trigger state=1 corresponds to L different CSI reporting sub-configurations.

[0119] The second trigger state configuration, such as a non-dedicated trigger state configuration, trigger state>1, etc. corresponds to a subset of the full set of CSI reporting sub-configurations supported by the network. For example, the network is configured with L CSI reporting sub-configurations in total, trigger state>1 corresponds to N different CSI reporting sub-configurations, and N is less than or equal to L.

[0120] The method for sending a CSI report provided in an embodiment of the present application triggers part or all of the CSI reporting sub-configurations configured on the network side through the activation / trigger information of the first trigger state configuration and the second trigger state configuration, supports a CSI reporting configuration with multiple sub-configurations, and enables the terminal to report multiple CSI frames in one CSI report instance, each CSI frame corresponds to a CSI sub-configuration, and a CSI sub-configuration corresponds to an antenna pattern, so that when different TXRUs are turned off and on, the change in channel state caused by the change in antenna pattern is well reflected, and better link adaptation and better transmission performance are achieved, achieving a balance between network energy consumption and network performance. The first trigger state configuration corresponds to the full set of CSI reporting sub-configurations supported by the network, so that the terminal can clearly understand the maximum number of CSI reporting sub-configurations.

[0121] Optionally, the association relationship between the trigger status configuration and the CSI reporting sub-configuration includes:

[0122] ① The trigger state configuration is indirectly (implicitly) associated with the CSI reporting sub-configuration. The configuration information also includes the CSI reporting configuration, and the trigger state configuration is associated with the CSI reporting sub-configuration through the CSI reporting configuration.

[0123] For example, a trigger state is associated with at least one CSI-ReportConfig, and a CSI-ReportConfig is associated with L sub-configuration parameters, where L is the parameter of the full set of sub-configurations supported by the network. That is, a trigger state is implicitly associated with L sub-configurations.

[0124] Figure 4 This is a flowchart of the non-periodic CSI measurement and reporting provided by the embodiment of the present application.

[0125] Second, such as Figure 4 As shown, the trigger state configuration is configured through CSI reporting configuration and CSI

[0126] The process of non-periodic CSI measurement and reporting in case of reporting sub-configuration association. The network side configures L CSI reporting sub-configurations in total, and the first information is used to trigger the N CSI reporting sub-configurations contained therein.

[0127] ② The trigger status configuration and the CSI reporting sub-configuration are directly (explicitly) associated.

[0128] For example, a trigger state is associated with at least one CSI-ReportConfig and L sub-configuration parameters; that is, a trigger state is explicitly associated with L sub-configurations.

[0129] Figure 5 This is a third flow chart of the non-periodic CSI measurement and reporting process provided in the embodiment of the present application, such as Figure 5 As shown, the process of non-periodic CSI measurement and reporting is shown when the trigger state configuration is independently associated with the CSI reporting configuration and the CSI reporting sub-configuration. The network side configures a CSI reporting sub-configuration list, which includes L CSI reporting sub-configurations, and the first information is used to trigger N of the CSI reporting sub-configurations.

[0130] The CSI report sending method provided in the embodiment of the present application triggers part or all of the CSI reporting sub-configuration configured on the network side through the first information, and further clarifies the relationship between the CSI reporting sub-configuration and the trigger status configuration, supports CSI reporting configuration with multiple sub-configurations, so that the terminal can report multiple CSI frames in one CSI reporting instance, each CSI frame corresponds to a CSI sub-configuration, and a CSI sub-configuration corresponds to an antenna pattern, so that when different TXRUs are turned off and on, the change in channel state caused by the change in antenna pattern is well reflected, thereby achieving better link adaptation and better transmission performance, and achieving a balance between network energy consumption and network performance.

[0131] Optionally, different trigger state configurations are associated with subsets of the full set of CSI reporting subconfigurations supported by the network.

[0132] Specifically, different trigger state configurations are associated with subsets of the full set of CSI reporting subconfigurations supported by the network. For example, trigger state configuration 1 is associated with N1 CSI reporting subconfigurations, trigger state configuration 2 is associated with N2 CSI reporting subconfigurations, and trigger state configuration X is associated with N X CSI reporting sub-configurations. The CSI reporting sub-configurations associated with all trigger status configurations together constitute the full set of CSI reporting sub-configurations supported by the network. That is, N1+N2+…+N X =L.

[0134] Fourth, such as Figure 6 As shown, the trigger state configuration is configured through CSI reporting configuration and CSI

[0135] The reporting sub-configurations are associated, and different trigger state configurations are associated with subsets of the full set of CSI reporting sub-configurations supported by the network. Trigger state configuration 1 is associated with CSI reporting configuration 1, CSI reporting configuration 1 includes N1 CSI reporting sub-configurations, and the first information is used to trigger N1 CSI reporting sub-configurations; trigger state configuration 2 is associated with CSI reporting configuration 2, CSI reporting configuration 2 includes N2 CSI reporting sub-configurations, and the first information is used to trigger N2 CSI reporting sub-configurations. N1+N2=L.

[0136] Figure 7 This is a fifth flow chart of the non-periodic CSI measurement and reporting process provided in the embodiment of the present application, such as Figure 7 As shown, it is shown that the trigger state configuration is independently associated with the CSI reporting configuration and the CSI reporting sub-configuration, and different trigger state configurations are associated with subsets of the full set of CSI reporting sub-configurations supported by the network. The network side configures a CSI reporting sub-configuration list, of which there are 2 CSI reporting sub-configuration subsets, sub-configuration N1-sub-set contains 3 CSI reporting sub-configurations, and the first information is used to trigger the 3 CSI reporting sub-configurations; sub-configuration N2-sub-set contains 2 CSI reporting sub-configurations, and the first information is used to trigger the 2 CSI reporting sub-configurations. At this time, the number of CSI reporting sub-configurations supported by the network side is 5.

[0137] Optionally, different trigger state configurations are associated with a full set of CSI reporting sub-configurations supported by the network.

[0138] Specifically, the network side only configures the full set of CSI reporting sub-configurations, which includes L CSI reporting sub-configurations. Each trigger state configuration is associated with L CSI reporting sub-configurations.

[0139] The CSI report sending method provided in the embodiment of the present application triggers part or all of the CSI reporting sub-configuration configured on the network side through the first information, and further clarifies the relationship between the CSI reporting sub-configuration and the trigger status configuration, supports CSI reporting configuration with multiple sub-configurations, so that the terminal can report multiple CSI frames in one CSI reporting instance, each CSI frame corresponds to a CSI sub-configuration, and a CSI sub-configuration corresponds to an antenna pattern, so that when different TXRUs are turned off and on, the change in channel state caused by the change in antenna pattern is well reflected, thereby achieving better link adaptation and better transmission performance, and achieving a balance between network energy consumption and network performance.

[0140] Optionally, the association relationship between the trigger status configuration and the CSI reporting sub-configuration is indicated by a code point (Codepoint) of the dynamic signaling sent by the network device.

[0141] Optionally, the trigger state configuration and the CSI reporting sub-configuration are configured through high-layer signaling.

[0142] Specifically, the high-level signaling configures the trigger status configuration and the CSI reporting sub-configuration.

[0143] For example, high-level signaling configures CSI reporting sub-configuration [N1, N2, N3, ... N T ] and trigger state configuration [trigger_state_1,trigger_state_2,trigger_state_3,,…trigger_state_T].

[0144] Optionally, the code point indication trigger_state_X of the dynamic signaling, code point X corresponds to trigger state configuration X, corresponding to N X CSI reporting sub-configuration.

[0145] Optionally, the code point indication trigger_state_X of the dynamic signaling, code point X corresponds to trigger state configuration X, corresponds to CSI reporting configuration X, and CSI reporting configuration X corresponds to N X CSI reporting sub-configuration.

[0146] Optionally, the first information is included in RRC signaling and / or dynamic signaling sent by the network device.

[0147] Specifically, the first information may be carried by RRC signaling and / or dynamic signaling sent by the network device. Optionally, the dynamic signaling is, for example, dynamic signaling indicated by DCI and / or MAC CE.

[0148] Dynamic signaling may specifically include: multiplexing existing DCI bit fields, for example, CSI request bit fields; configuring new DCI bit fields; multiplexing existing DCI bit fields; or configuring new MAC-CE information bit indication.

[0149] Taking the reuse of the existing DCI bit field as an example, at least one of the following implementation solutions may be included:

[0151] Furthermore, for Rel-18 UE, whether the CSI reporting configuration contains relevant configuration of the CSI reporting sub-configuration can be obtained through the CSI reporting configuration, so that when receiving the CSI reporting configuration, it can be determined whether the bit in the DCI is used for multiple CSI reporting sub-configurations.

[0152] For Rel-17 UE, no CSI reporting sub-configuration is configured, so traditional DCI reception and CSI reporting are performed;

[0153] ②DCI-1 includes at least two bit domain information, Nbit and Mbit, which are used to activate / indicate the trigger status configuration using the traditional N bit, and use the newly defined M bit to activate / indicate the CSI reporting sub-configuration.

[0154] ③DCI-1, including at least Nbit information field, used to activate / indicate trigger status configuration; DCI-2, including at least Mbit information field, used to activate / indicate CSI reporting sub-configuration;

[0155] Optionally, the first information is also used to indicate the number and / or index (Index) of partial CSI reporting sub-configurations.

[0156] Optionally, the RRC signaling and / or dynamic signaling also indicates the number and / or index of CSI reporting sub-configurations that the UE needs to report.

[0157] Likewise, the configuration information may also be carried via RRC signaling and / or dynamic signaling.

[0158] The CSI report sending method provided in the embodiment of the present application triggers part or all of the CSI reporting sub-configuration configured on the network side through the first information, and further clarifies the relationship between the CSI reporting sub-configuration and the trigger status configuration, supports CSI reporting configuration with multiple sub-configurations, so that the terminal can report multiple CSI frames in one CSI reporting instance, each CSI frame corresponds to a CSI sub-configuration, and a CSI sub-configuration corresponds to an antenna pattern, so that when different TXRUs are turned off and on, the change in channel state caused by the change in antenna pattern is well reflected, thereby achieving better link adaptation and better transmission performance, and achieving a balance between network energy consumption and network performance.

[0159] Figure 8 is a flow chart of a method for receiving a CSI report provided in an embodiment of the present application, such as Figure 8 As shown, the execution subject of the method is a network device, such as a base station, and the method includes at least the following steps:

[0160] Step 801: Send configuration information and first information to a terminal;

[0161] Step 802: Receive a CSI report sent by the terminal based on the configuration information and the first information.

[0162] The configuration information includes: a CSI reporting sub-configuration, a trigger status configuration, and an association relationship between the trigger status configuration and the CSI reporting sub-configuration; the first information is used to trigger part or all of the CSI reporting sub-configuration.

[0163] Specifically, the network device sends configuration information and first information to the terminal. The configuration information includes at least CSI reporting sub-configuration, trigger state configuration, and the association relationship between the trigger state configuration and the CSI reporting sub-configuration. The first information is used to trigger part or all of the CSI reporting sub-configuration. The first information is, for example, trigger state activation / trigger information.

[0164] For example, the network side configures L CSI reporting sub-configurations, and the first information is used to trigger N CSI reporting sub-configurations among the L CSI sub-configurations, where N is less than or equal to L, and both N and L are integers greater than 0.

[0165] The configuration information at least includes:

[0166] CSI reporting subconfiguration. One CSI reporting subconfiguration corresponds to one adaptive spatial pattern (antenna pattern). Optionally, the CSI reporting subconfiguration includes at least one of the following: a spatial adaptation indication for supporting CSI reporting enhancement based on spatial adaptation; antenna array size parameters n1-n2, used to determine a subset of the MIMO codebook; antenna panel number Ng for helping to determine the multi-panel MIMO codebook; activated antenna port index corresponding to the spatial adaptive pattern; power offset of CSI-RS relative to SSB based on the spatial adaptive pattern; antenna array size information, including the number of antenna array horizontal dimensions N1 and the number of antenna array vertical dimensions N2 for single-panel, and the number of antenna array horizontal dimensions N1, the number of antenna array vertical dimensions N2, and the number of antenna panels Ng for multi-panel; port subset indication; index of PMI or precoding matrix; rank restriction.

[0167] The associated configuration of the CSI reporting sub-configuration includes a trigger state configuration associated with the CSI reporting sub-configuration, such as trigger state. In the associated configuration of the CSI reporting sub-configuration, the association relationship between the CSI reporting sub-configuration and the trigger state configuration is indicated.

[0168] Optionally, the configuration information also includes at least one of the following:

[0169] CSI reporting configuration. Optionally, the CSI reporting configuration includes at least one of the following: CSI reporting configuration ID, resource configuration for channel measurement, resource configuration for interference measurement, reporting configuration type, reporting quality, reporting frequency domain configuration, channel measurement time domain restriction, interference measurement time domain restriction, codebook configuration, group-based beam reporting, CQI table, subband size, non-PMI port indication, PUSCH-based semi-persistent CSI reporting parameters, non-periodic CSI reporting parameters, reporting quality, shared CMR configuration (Sharing of Channel Measurement Resources), CSI reporting mode configuration, single TRP CSI mode 1 number configuration, CSI reporting period and offset, PUCCH resources for CSI reporting, and 8-rank port index parameters.

[0170] The associated configuration of the CSI reporting configuration includes a trigger state configuration associated with the CSI reporting configuration, such as triggerstate, which includes an association relationship between the CSI reporting configuration and the trigger state, such as one trigger state is associated with at least one CSI reporting configuration, and one CSI reporting configuration is associated with one trigger state, etc.

[0171] The terminal performs CSI reporting based on the first information and the configuration information, and the network device sends a CSI report to the terminal. Optionally, the CSI report includes an antenna pattern in a CSI reporting sub-configuration triggered by the first information.

[0172] The CSI report sending method provided in the embodiment of the present application triggers part or all of the CSI reporting sub-configurations configured on the network side through the first information, supports a CSI reporting configuration with multiple sub-configurations, so that the terminal can report multiple CSI frames in one CSI reporting instance, each CSI frame corresponds to a CSI sub-configuration, and a CSI sub-configuration corresponds to an antenna pattern. Therefore, when different TXRUs are turned off and on, the changes in the channel state caused by the changes in the antenna pattern are well reflected, thereby achieving better link adaptation and better transmission performance, and achieving a balance between network energy consumption and network performance.

[0173] Optionally, the trigger state configuration includes a first trigger state configuration and a second trigger state configuration; the first trigger state configuration is associated with the full set of CSI reporting sub-configurations supported by the network; and the second trigger state configuration is associated with a subset of the full set of CSI reporting sub-configurations supported by the network.

[0174] Specifically, the trigger state configuration can be divided into two categories: a first trigger state configuration and a second trigger state configuration.

[0175] The first trigger state configuration may be a dedicated trigger state configuration, such as Dedicated triggerstate, trigger state=1, etc. The corresponding network supports the full set of CSI reporting sub-configurations. For example, the network configures L CSI reporting sub-configurations, and trigger state=1 corresponds to L different CSI reporting sub-configurations.

[0176] The second trigger state configuration, such as a non-dedicated trigger state configuration, trigger state>1, etc. corresponds to a subset of the full set of CSI reporting sub-configurations supported by the network. For example, the network is configured with L CSI reporting sub-configurations in total, trigger state>1 corresponds to N different CSI reporting sub-configurations, and N is less than or equal to L.

[0177] The CSI report receiving method provided in the embodiment of the present application triggers part or all of the CSI reporting sub-configurations configured on the network side through the activation / trigger information of the first trigger state configuration and the second trigger state configuration, supports CSI reporting configurations with multiple sub-configurations, and enables the terminal to report multiple CSI frames in one CSI report instance, each CSI frame corresponds to a CSI sub-configuration, and a CSI sub-configuration corresponds to an antenna pattern, so that when different TXRUs are turned off and on, the change in channel state caused by the change in antenna pattern is well reflected, and better link adaptation and better transmission performance are achieved, achieving a balance between network energy consumption and network performance. The first trigger state configuration corresponds to the full set of CSI reporting sub-configurations supported by the network, so that the terminal can clearly know the maximum number of CSI reporting sub-configurations.

[0178] Optionally, the association relationship between the trigger status configuration and the CSI reporting sub-configuration includes:

[0179] ① The trigger state configuration is indirectly (implicitly) associated with the CSI reporting sub-configuration. The configuration information also includes the CSI reporting configuration, and the trigger state configuration is associated with the CSI reporting sub-configuration through the CSI reporting configuration.

[0180] ② The trigger status configuration and the CSI reporting sub-configuration are directly (explicitly) associated.

[0181] For example, a trigger state is associated with at least one CSI-ReportConfig and L sub-configuration parameters; that is, a trigger state is explicitly associated with L sub-configurations.

[0182] The CSI report receiving method provided in the embodiment of the present application triggers part or all of the CSI reporting sub-configuration configured on the network side through the first information, and further clarifies the relationship between the CSI reporting sub-configuration and the trigger status configuration, supports CSI reporting configuration with multiple sub-configurations, so that the terminal can report multiple CSI frames in one CSI reporting instance, each CSI frame corresponds to a CSI sub-configuration, and a CSI sub-configuration corresponds to an antenna pattern, so that when different TXRUs are turned off and on, the change in channel state caused by the change in antenna pattern is well reflected, thereby achieving better link adaptation and better transmission performance, and achieving a balance between network energy consumption and network performance.

[0183] Optionally, different trigger state configurations are associated with subsets of the full set of CSI reporting subconfigurations supported by the network.

[0184] Specifically, different trigger state configurations are associated with subsets of the full set of CSI reporting subconfigurations supported by the network. For example, trigger state configuration 1 is associated with N1 CSI reporting subconfigurations, trigger state configuration 2 is associated with N2 CSI reporting subconfigurations, and trigger state configuration X is associated with N X CSI reporting sub-configurations. The CSI reporting sub-configurations associated with all trigger status configurations together constitute the full set of CSI reporting sub-configurations supported by the network. That is, N1+N2+…+N X =L.

[0185] Optionally, different trigger state configurations are associated with a full set of CSI reporting sub-configurations supported by the network.

[0186] Specifically, the network side only configures the full set of CSI reporting sub-configurations, which includes L CSI reporting sub-configurations. Each trigger state configuration is associated with L CSI reporting sub-configurations.

[0187] The CSI report receiving method provided in the embodiment of the present application triggers part or all of the CSI reporting sub-configuration configured on the network side through the first information, and further clarifies the relationship between the CSI reporting sub-configuration and the trigger status configuration, supports CSI reporting configuration with multiple sub-configurations, so that the terminal can report multiple CSI frames in one CSI reporting instance, each CSI frame corresponds to a CSI sub-configuration, and a CSI sub-configuration corresponds to an antenna pattern, so that when different TXRUs are turned off and on, the change in channel state caused by the change in antenna pattern is well reflected, thereby achieving better link adaptation and better transmission performance, and achieving a balance between network energy consumption and network performance.

[0189] Optionally, the trigger state configuration and the CSI reporting sub-configuration are configured through high-layer signaling.

[0190] Specifically, the high-level signaling configures the trigger status configuration and the CSI reporting sub-configuration.

[0191] For example, high-level signaling configures CSI reporting sub-configuration [N1, N2, N3, ... N T ] and trigger state configuration [trigger_state_1,trigger_state_2,trigger_state_3,…trigger_state_T].

[0192] Optionally, the code point indication trigger_state_X of the dynamic signaling, code point X corresponds to trigger state configuration X, corresponding to N X CSI reporting sub-configuration.

[0193] Optionally, the code point indication trigger_state_X of the dynamic signaling, code point X corresponds to trigger state configuration X, corresponds to CSI reporting configuration X, and CSI reporting configuration X corresponds to N X CSI reporting sub-configuration.

[0194] Optionally, the first information is included in RRC signaling and / or dynamic signaling sent by the network device.

[0195] Specifically, the first information may be carried by RRC signaling and / or dynamic signaling sent by the network device. Optionally, the dynamic signaling is, for example, dynamic signaling indicated by DCI and / or MAC CE.

[0196] Dynamic signaling may specifically include: multiplexing existing DCI bit fields, for example, CSI request bit fields; configuring new DCI bit fields; multiplexing existing DCI bit fields; or configuring new MAC-CE information bit indication.

[0197] Taking the reuse of the existing DCI bit field as an example, at least one of the following implementation solutions may be included:

[0199] Furthermore, for Rel-18 UE, whether the CSI reporting configuration contains relevant configuration of the CSI reporting sub-configuration can be obtained through the CSI reporting configuration, so that when receiving the CSI reporting configuration, it can be determined whether the bit in the DCI is used for multiple CSI reporting sub-configurations.

[0200] For Rel-17 UE, no CSI reporting sub-configuration is configured, so traditional DCI reception and CSI reporting are performed;

[0201] ②DCI-1 includes at least two bit domain information, Nbit and Mbit, which are used to activate / indicate the trigger status configuration using the traditional N bit, and use the newly defined M bit to activate / indicate the CSI reporting sub-configuration.

[0202] ③DCI-1, including at least Nbit information field, used to activate / indicate trigger status configuration; DCI-2, including at least Mbit information field, used to activate / indicate CSI reporting sub-configuration;

[0203] Optionally, the first information is also used to indicate the number and / or index (Index) of partial CSI reporting sub-configurations.

[0204] Optionally, the RRC signaling and / or dynamic signaling also indicates the number and / or index of CSI reporting sub-configurations that the UE needs to report.

[0205] Likewise, the configuration information may also be carried via RRC signaling and / or dynamic signaling.

[0206] The CSI report receiving method provided in the embodiment of the present application triggers part or all of the CSI reporting sub-configuration configured on the network side through the first information, and further clarifies the relationship between the CSI reporting sub-configuration and the trigger status configuration, supports CSI reporting configuration with multiple sub-configurations, so that the terminal can report multiple CSI frames in one CSI reporting instance, each CSI frame corresponds to a CSI sub-configuration, and a CSI sub-configuration corresponds to an antenna pattern, so that when different TXRUs are turned off and on, the change in channel state caused by the change in antenna pattern is well reflected, thereby achieving better link adaptation and better transmission performance, and achieving a balance between network energy consumption and network performance.

[0207] The technical solution of the embodiments of the present application is further described below through several specific examples.

[0208] Example 1: Each trigger state configuration is associated with L different CSI reporting sub-configurations, and each trigger state activation signaling activates N different CSI reporting sub-configurations. The CSI measurement and reporting process includes:

[0209] Step 1: The base station configures the following information through RRC signaling: CSI reporting configuration, CSI reporting sub-configuration, CSI reporting configuration and / or associated configuration of CSI reporting sub-configuration.

[0210] Among them, the CSI reporting configuration includes at least one of the following: CSI reporting configuration ID, resource configuration for channel measurement, resource configuration for interference measurement, reporting configuration type, reporting quality, reporting frequency domain configuration, channel measurement time domain restriction, interference measurement time domain restriction, codebook configuration, group-based beam reporting, CQI table, subband size, non-PMI port indication, PUSCH-based semi-continuous CSI reporting parameters, non-periodic CSI reporting parameters, reporting quality, shared CMR configuration (Sharing of Channel Measurement Resources), CSI reporting mode configuration, single TRP CSI mode 1 number configuration, CSI reporting period and offset, CSI reporting PUCCH resources, 8rank port index parameters.

[0211] A CSI reporting subconfiguration, used to associate different antenna patterns, includes at least one of the following: a spatial adaptation indication for supporting CSI reporting enhancement based on spatial adaptation; antenna array size parameters n1-n2, used to determine a subset of the MIMO codebook; an antenna panel number Ng for helping to determine a multi-panel MIMO codebook; an activated antenna port index corresponding to the spatial adaptation pattern; a power offset of the CSI-RS relative to the SSB based on the spatial adaptation pattern; antenna array size information, including the number of antenna array horizontal dimensions N1 and the number of antenna array vertical dimensions N2 for a single-panel, and the number of antenna array horizontal dimensions N1 and the number of antenna array vertical dimensions N2, as well as the number of antenna panels Ng for multi-panels; a port subset indication; an index of the PMI or precoding matrix; and a rank restriction.

[0212] The associated configuration of the CSI reporting configuration is used to indicate the indication signaling of the CSI reporting configuration, including the trigger state configuration associated with the CSI device configuration, such as trigger state. For details, please refer to Table 1.

[0213] The associated configuration of the CSI reporting sub-configuration includes at least one of the following: a trigger state configuration associated with the CSI reporting sub-configuration (eg, trigger state), and a CSI reporting configuration associated with the CSI reporting sub-configuration (eg, CSI-ReportConfig).

[0214] Specifically, at least the following two solutions may be included:

[0215] ① A trigger state is associated with at least one CSI-ReportConfig, and a CSI-ReportConfig is associated with L sub-configuration parameters, where L is the parameter of the full set of sub-configurations supported by the network; that is, a trigger state is implicitly associated with L sub-configurations;

[0216] ② A trigger state is associated with at least one CSI-ReportConfig and L sub-configuration parameters; that is, a trigger state is explicitly associated with L sub-configurations.

[0217] For details, please refer to Table 2 and Table 3:

[0218] Table 2: CSI reporting sub-configuration associated configuration

[0219]

[0220] Table 3: CSI reporting sub-configuration associated configuration

[0221]

[0222]

[0223] Step 2: The base station configures and / or dynamically signals to activate / instruct transmission of the CSI reporting sub-configuration. Specifically:

[0224] Dynamic signaling, including dynamic signaling indicated by DCI and / or MAC-CE, is used to indicate CSI reporting sub-configuration information, including at least one of the following: multiplexing an existing DCI bit field, for example, a CSI request bit field; configuring a new DCI bit field; multiplexing an existing DCI bit field; or configuring a new MAC-CE information bit indication; for example, taking DCI as an example, taking multiplexing an existing DCI bit field as an example, at least one of the following configuration schemes may be included:

[0225] ① The bit field used to activate / indicate the trigger state in DCI is configured as N bits, where N1 bit is used to activate / indicate the trigger state, and N2 bit is used to activate / indicate the CSI reporting sub-configuration; N1+N2=N; further,

[0226] For Rel-18 UE, CSI-ReportConfig can be used to determine whether the sub-configuration is included in it, so that when ReportConfig is received, it can be determined whether the bit in the DCI is used for multiple CSI reporting sub-configurations;

[0227] For Rel-17 UE, no CSI reporting sub-configuration is configured, so legacy DCI reception and CSI reporting are performed;

[0228] ②DCI-1 includes at least two bit fields, Nbit and Mbit, which are used to activate / indicate the trigger state using the legacy N bit and the newly defined M bit to activate / indicate the sub-configuration configuration;

[0229] ③DCI-1, including at least N bits of information field, used to activate / indicate the trigger state; DCI-2, including at least M bits of information field, used to activate / indicate the sub-configuration configuration;

[0230] Further, the dynamic signaling activation / indication of sub-configuration includes at least one of the following: the number N of sub-configurations reported by the DCI indicating the CSI; the index of the sub-configuration reported by the DCI indicating the CSI, which may be specifically referred to in Table 4:

[0231] Table 4: Index of DCI indicating CSI reporting sub-configuration

[0232]

[0233] Step 3: The base station receives the CSI report corresponding to the CSI reporting sub-configuration information at the first time.

[0234] The first time may include at least one of the following: a first moment, a first time window, a second moment that satisfies the first rule, and a second time window that satisfies the second rule. The first moment may be the first wireless frame, the first subframe, the first time slot, or the first symbol. The first time window includes a time window from a first reference moment to a second reference moment; the reference moment may include a moment relative to the first signal / channel. The first rule may be to take the maximum value, the minimum value, or the average value. The second rule may be that the starting moment is greater than the first target moment, the starting moment is less than the second target moment, the ending moment is greater than the third target moment, and the ending moment is less than the third target moment; the target moment may be the transmission moment of the first target signal / channel.

[0235] For example, the base station simultaneously receives CSI reports corresponding to multiple CSI reporting sub-configurations. For example, the base station receives CSI reports corresponding to the sub-configuration with the smallest reporting delay of multiple CSI reporting sub-configurations. For example, the base station receives CSI reports corresponding to the sub-configuration with the largest reporting delay of multiple CSI reporting sub-configurations. For example, the base station receives CSI reports corresponding to multiple CSI reporting sub-configurations within a target time window. For example, the base station receives CSI reports corresponding to all CSI reporting sub-configurations that meet the CSI reporting time requirements.

[0236] For the UE, it receives the relevant configuration information sent by the base station, and reports the antenna pattern corresponding to the CSI reporting sub-configuration according to the configuration information and dynamic signaling.

[0237] Example 2: Each trigger state configuration is associated with L different CSI reporting sub-configurations, and each trigger state activation signaling activates N different CSI reporting sub-configurations. The CSI measurement and reporting process includes:

[0238] Step 1: The base station configures the following information through RRC signaling: CSI reporting configuration, CSI reporting sub-configuration, CSI reporting configuration and / or associated configuration of CSI reporting sub-configuration.

[0241] Specifically, at least the following two solutions may be included:

[0242] ① A trigger state is associated with at least one CSI-ReportConfig, and a CSI-ReportConfig is associated with N sub-configuration parameters, where N is a subset of the sub-configuration parameters supported by the network; that is, multiple N sub-configurations implicitly associated with multiple trigger states together constitute the full set of sub-configuration parameters supported by the network, that is, L sub-configurations;

[0243] ② A trigger state is associated with at least one CSI-ReportConfig and N sub-configuration parameters; that is, multiple N sub-configurations explicitly associated with multiple trigger states together constitute the full set of sub-configuration parameters supported by the network, that is, L sub-configurations.

[0246]

[0247]

[0248] Table 6: CSI reporting sub-configuration associated configuration

[0249]

[0250] Step 2: The base station configures and / or dynamically signals to activate / instruct transmission of the CSI reporting sub-configuration. The details are the same as in Example 1.

[0251] Step 3: The base station receives the CSI report corresponding to the CSI reporting sub-configuration information at the first time. The details are the same as in Example 1.

[0252] Example 3: A dedicated trigger state configuration (trigger state=1) is associated with L different CSI reporting sub-configurations, and a non-dedicated trigger state configuration (trigger state>1) is associated with N different CSI reporting sub-configurations. The CSI measurement and reporting process includes:

[0256] Specifically, at least the following two solutions may be included:

[0257] ① A trigger state is associated with at least one CSI-ReportConfig. One type of CSI-ReportConfig is associated with L sub-configuration parameters, where L is the full set of sub-configuration parameters supported by the network; another type of CSI-ReportConfig is associated with N sub-configuration parameters, where N is a subset of sub-configuration parameters supported by the network.
