Description

Technical Field

[0001] The present invention belongs to the field of communication technology, and in particular to an information transmission method and device. Prior Art

[0002] Compared to the fourth generation mobile communication technology (4G), New Radio (NR) systems require support for high frequency bands, wide bandwidth, and massive antenna technology. While improving system performance, the power consumption of fifth generation mobile communication technology (5G) base stations has increased to two to three times that of 4G base stations. Energy consumption is a key indicator of an operator's operating expense (OPEX). According to operator data, energy consumption in mobile networks accounts for 23% of total OPEX, becoming a significant burden for the widespread deployment of 5G networks. This energy issue also limits its application in vertical industries and the widespread adoption of 5G terminals. Field measurements show that the majority of base station energy consumption comes from the radio access network, particularly the active antenna units (AAUs) in massive antenna arrays. Reducing base station energy consumption is an urgent issue. Summary of the Invention

[0060] Figure 1 illustrates a wireless communication system applicable to embodiments of the present invention. The wireless communication system includes a terminal device 11 and a network-side device 12. Terminal device 11 may also be referred to as a terminal or user equipment (UE). It should be noted that the specific type of terminal 11 is not limited in this embodiment of the present invention. Network-side device 12 may be a base station or a core network. It should be noted that this embodiment of the present invention uses a base station in a NR system as an example, but does not limit the specific type of base station.

[0061] In order to enable those with ordinary knowledge in this technical field to better understand the embodiments of the present invention, the following description is first given.

[0062] Base stations can consider shutting down multiple antenna channels, such as antenna ports or certain antenna panels. When certain channels are shut down, the corresponding antenna ports are deactivated. Compared to 4G base stations, 5G base stations have a dramatically increased number of channels. Channel shutdown not only reduces power amplifier power consumption but also reduces the static power consumption of the channels. Base station manufacturers have adopted channel shutdown as a mainstream energy-saving solution. Compared to shutting down the base station in the time domain, channel shutdown offers significant advantages in ensuring service continuity, and its application is not limited to base station traffic under light load.

[0063] The measurement and reporting of Channel State Information (CSI) are closely related to the CSI framework. The CSI Framework consists of two parts: resource configuration and reporting configuration. Resource configuration is used to configure the CSI reference signal, corresponding to the high-level signaling CSI resource configuration information element (CSI-ResourceConfig IE, IE stands for Information Element). Each CSI-ResourceConfig contains at least one non-zero power channel state information reference signal synchronization signal (NZP-CSI-RS-SSB) and / or at least one non-zero power channel state information reference signal resource set (NZP-CSI-RS-ResourceSet). Each NZP-CSI-RS-ResourceSet contains at least one NZP-CSI-RS-Resource. Reporting Setting is mainly completed through the radio resource control (RRC) layer signaling CSI reporting configuration element (CSI-ReportConfig IE), which is used to configure the CSI reporting behavior. Each CSI-ReportConfig is associated with one or more resource configurations (CSI-ResourceConfig), indicating the resource configuration used for channel measurement and / or interference measurement.In addition, each CSI-ReportConfig also includes: CSI reporting time domain behavior, including periodic (Periodic), semi-persistent (semiPersistentOnPUCCH) based on the physical uplink control channel (PUCCH), semi-persistent (semiPersistentOnPUSCH) based on the physical uplink shared channel (PUSCH), aperiodic (Aperiodic) CSI reporting type and corresponding reporting period, offset and other reporting resource configurations; CSI reporting related frequency domain behavior, such as the frequency domain granularity of channel quality indicator (CQI) and precoding matrix indicator (PMI), including broadband and subband; measurement restriction configuration, including channel measurement restriction and interference measurement restriction; CSI related indication quantity reported by UE, including CQI, PMI, channel state information reference signal resource indicator (CSI-RS Resource Indicator, CRI), synchronization signal physical broadcast channel block resource indicator (SS / PBCH Configuration parameters include the Block Resource Indicator (SSBRI), Layer Indicator (LI), Rank Indicator (RI), Layer 1 Reference Signal Received Power (L1-RSRP), or Layer 1 Signal-to-Noise and Interference Ratio (L1-SINR). In addition, each CSI-Report Config also includes codebook configurations, including Type I, Type II, or enhanced Type II codebooks, as well as codebook restriction subsets. The Third Generation Partnership Projects (3GPP) New Radio (NR) protocol supports CSI-RS port counts of 1, 2, 4, 8, 16, 24, and 32. Typically, multiple CSI-RS antenna ports can be mapped into a two-dimensional antenna array. An example of a 32-port array is shown in Figures 2 and 3.

[0064] The antenna port array described above includes N1 dual-polarized antennas in the horizontal direction and N2 dual-polarized antennas in the vertical direction. Ng is the number of antenna panels (also called panels). Figure 2 illustrates a single antenna panel with 32 antenna ports, while Figure 3 illustrates the aggregation of multiple panels to generate 32 antenna ports.

[0065] Related technologies support both Type 1 and Type 2 shutdown methods to support airspace self-adjustment shutdown. Type 1 shutdown directly shuts down different antenna ports, while Type 2 shutdown shuts down some antenna elements associated with the antenna port without activating the antenna port. Supporting different types of airspace shutdown requires the UE to perform channel measurements on the CSI Reference Signals (CSI-RS) associated with different antenna ports and report the measurement results. However, related technologies have a limited number of CSI report configurations (CSI-Report Configs) that can be used for channel measurement, resulting in some Channel State Information (CSI) not being reported in a timely manner. Multiple CSI reports will undoubtedly increase CSI-RS transmit power and system consumption on the base station side, while also increasing UE measurement complexity and UE feedback consumption. Therefore, enhancements to related technologies are necessary.

[0066] As shown in FIG4 , an embodiment of the present invention provides an information transmission method, including: Step 401: The terminal obtains first indication information, where the first indication information includes spatial adaptation indication information and / or power domain adaptation indication information.

[0067] In some embodiments, the spatial self-adjustment indication information is associated with a reference signal resource, and the power domain self-adjustment indication information is associated with a reference signal resource. The spatial self-adjustment information may also be described as spatial antenna element self-adjustment indication information or spatial indication information. The reference signal resource may be a CSI-RS.

[0068] Step 402: The terminal measures the reference signal resource associated with the first indication information and reports the measurement result.

[0069] In the above-mentioned solution of an embodiment of the present invention, a terminal obtains first indication information, which includes spatial domain self-adjustment indication information and / or power domain self-adjustment indication information; the terminal measures the reference signal resources associated with the first indication information and reports the measurement results. Through this solution, the terminal can self-adjust to determine the reference signal resources to be measured and report the measurement results, allowing network-side equipment to self-adjust antenna power or the activation and deactivation of antenna ports based on the measurement results, thereby reducing energy consumption of the base station.

[0070] The embodiments of the present invention are defined from the perspectives of configuration of first indication information, enhancement of airspace self-adjustment and reporting enhancement, and update of airspace self-adjustment and / or power domain self-adjustment. The specific implementation of the present invention is described in detail below based on these situations. It should be noted that these situations can be used individually or in combination in specific implementations.

[0071] Solution 1: Configuration of the first instruction information.

[0072] In some embodiments, the airspace self-adjustment indication information includes at least one of the following: Spatial self-adaptation type information indicates whether the spatial adaptation type is Type 1 spatial adaptation or Type 2 spatial adaptation. Type 1 spatial adaptation directly shuts down different antenna ports, while Type 2 spatial adaptation shuts down some antenna elements associated with an antenna port without activating the antenna port. This spatial self-adaptation type information enables the terminal to determine whether to shut down different antenna ports or some antenna elements of an antenna port, thereby achieving spatial self-adaptation shutdown. Antenna port array-related information, the antenna port array-related information including at least one of antenna port number information, antenna panel information, and antenna dimension information, the antenna dimension information including first dimension information (e.g., horizontal direction) and second dimension information (e.g., vertical direction) related to the antenna array; Channel State Information Reference Signal (CSI-RS) resource-associated power information; Transmission Configuration Indicator (TCI) status indication information, the TCI status indication information is used to indicate the transmission beam information.

[0073] In some embodiments, the spatial self-adjustment indication information is spatial self-adjustment pattern information.

[0074] It should be noted that the spatial self-adjustment pattern or mode in the embodiments of the present invention can also be described as a spatial self-adjustment pattern, method, style, etc., and the above pattern can also be described as / mode.

[0075] In some embodiments, the terminal obtains airspace self-adjustment type information including: The terminal obtains the airspace self-adjustment type information through radio resource control RRC signaling or dynamic signaling; Alternatively, the terminal obtains the airspace self-adjustment type information through the antenna port array related information associated with the airspace self-adjustment indication information.

[0076] In an embodiment of the present invention, the terminal can explicitly obtain spatial self-adjustment type information using RRC signaling or dynamic signaling, or can implicitly obtain spatial self-adjustment type information through antenna port array related information associated with spatial self-adjustment indication information.

[0077] In some embodiments, when the spatial adaptation type information indicates a first spatial adaptation type (type 1 Spatial Adaptation, type 1 SA), each spatial adaptation pattern corresponds to an independent set of antenna port array related information, and / or the set of spatial adaptation patterns is associated with a CSI-RS resource (e.g., a first CSI-RS resource); When the spatial adaptation type information indicates a second spatial adaptation type (type 2 Spatial Adaptation, type 2 SA), multiple spatial adaptation patterns correspond to the same antenna port array-related information, and / or each CSI-RS resource (configured by a network-side device) corresponds to one such spatial adaptation pattern.

[0078] In this embodiment of the present invention, multiple spatial self-adjustment patterns / modes for type 1 SA are associated with a nested CSI-RS resource. Specifically, each spatial self-adjustment pattern is associated with a subset of the first CSI-RS resource. In this case, the UE can measure and report the optimal PMI based on different antenna port patterns. However, for type 2 SA, since the antenna ports remain unchanged but the switching off of spatial elements affects the transmit beamwidth and direction, the UE requires independently configured CSI-RS resources to obtain accurate CSI measurements and reporting.

[0079] The above solution 1 is described below with reference to specific embodiments.

[0080] In one embodiment of the present invention, a base station configures spatial self-adjustment indication information (or spatial indication information) for a terminal using RRC signaling or dynamic signaling, for example, spatial antenna element self-adjustment indication information. This spatial self-adjustment indication information includes at least one of the following: spatial self-adjustment type indication information, antenna port number information, antenna panel indication information, first and second dimension information related to the antenna array, spatial self-adjustment pattern indication information, and CSI-RS resource-related power information.

[0081] The spatial self-adjustment type indication information may use two phases of 1 bit to indicate type 1 spatial self-adjustment and type 2 spatial self-adjustment respectively; The number of antenna ports is the total number of antenna ports included in the activated antenna array;

[0082] Antenna panel indication information refers to the antenna panel identification in the multi-antenna panel; The first dimension and the second dimension refer to the dimensions n1, n2 of the two-dimensional antenna array, or the dimensions n1, n2 of the antenna array associated with the antenna panel; The spatial self-adjustment pattern / mode indication refers to identification information of the spatial self-adjustment pattern. For example, there are four spatial self-adjustment pattern identification information, such as index information 0, 1, 2, and 3, and each spatial self-adjustment pattern identification information corresponds to a different or the same antenna port based on type 1 spatial self-adjustment; or four spatial self-adjustment pattern identification information, such as index information 0, 1, 2, and 3, respectively corresponding to different or the same antenna shutoff modes of type 2 spatial self-adjustment, such as corresponding to non-shutoff spatial elements, shutoff 1 / 3 spatial elements, shutoff 1 / 2 spatial elements, and shutoff 1 / 4 spatial elements, respectively.

[0083] A: The airspace self-adjustment indication information includes explicit airspace self-adjustment type indication information: 1) If the spatial self-adjustment type indication information is equal to the first value (i.e., corresponding to type 2 spatial self-adjustment), the base station configures the spatial self-adjustment indication information for the UE using RRC signaling / dynamic signaling. All spatial self-adjustment patterns are configured with the same or a set of antenna port array-related information. For example, the antenna array-related information may include at least one of antenna port, antenna panel information, and antenna array dimensional information. When the spatial self-adjustment type indication information is equal to the first value, in some embodiments, the base station configures power information for each spatial self-adjustment pattern. For example, the power information is the power offset value between the CSI-RS and the SSB. The UE receives CSI-RS resources and performs CSI measurements based on the spatial self-adjustment pattern configured by the base station. 2) If the spatial self-adjustment type indication information is equal to the second value (i.e., corresponding to type 1 spatial self-adjustment), the base station configures the spatial self-adjustment indication information for the UE using RRC signaling / dynamic signaling. Each spatial self-adjustment pattern is independently configured with a set of antenna port array-related information. For example, the antenna array-related information may include at least one of antenna port, antenna panel information, and antenna array dimension information. When the spatial self-adjustment type indication information is equal to the second value, in some embodiments, the base station associates one or more power information for all spatial self-adjustment patterns. For example, the power information is the power offset value between the CSI-RS and the SSB.

[0084] B: The base station uses the airspace self-adjustment information to implicitly indicate the airspace self-adjustment type: When the base station configures spatial self-adjustment indication information for the UE using RRC signaling / dynamic signaling, if all spatial self-adjustment patterns are associated with a common spatial antenna port array information, the UE considers it to be Type 2 spatial self-adjustment. Otherwise, if each spatial self-adjustment pattern is associated with independent spatial antenna port array information, the UE considers it to be Type 1 spatial self-adjustment.

[0085] In an embodiment of the present invention, different spatial self-adjustment patterns based on Type 1 spatial self-adjustment may be configured with the same antenna port information. The base station indicates the spatial self-adjustment type to the UE through explicit or implicit configuration, which facilitates the UE to obtain the spatial self-adjustment type information, thereby assisting the UE in performing CSI measurement and reporting. Furthermore, it can achieve the joint design of Type 1 and Type 2 spatial self-adjustment information, reducing configuration signaling consumption.

[0086] Option 2: Enhanced airspace self-adjustment and reporting.

[0087] In some embodiments, the set of spatial self-adjustment patterns is associated with a channel state information reference signal CSI-RS resource; or, each CSI-RS resource (configured by a network-side device) corresponds to one of the spatial self-adjustment patterns / modes.

[0088] In this way, the association between the spatial self-adjustment pattern and the CSI-RS resources can be determined, so that the corresponding CSI-RS resources can be measured and reported according to the spatial self-adjustment pattern indicated by the network device.

[0089] In some embodiments, the base station configures a set of spatial self-adjustment patterns for the terminal using RRC signaling or dynamic signaling. The set of spatial self-adjustment patterns can be associated with a CSI-RS resource (such as the first CSI-RS resource) by pre-agreed agreement or configured through RRC signaling.

[0090] In an embodiment of the present invention, when each CSI-RS resource corresponds to one of the spatial self-adjustment patterns, preferably, the CSI-RS resource sets corresponding to the multiple spatial self-adjustment patterns are associated with the same CSI-RS resource set under the same report setting, or the CSI-RS resource sets corresponding to the multiple spatial self-adjustment patterns have the same frequency domain resources and / or the same or different time domain resources.

[0091] In some embodiments, when the set of spatial self-adjustment patterns is associated with a CSI-RS resource (such as the first CSI-RS resource described below), the identifier of the spatial self-adjustment pattern corresponding to the CSI-RS resource is the maximum or minimum identifier of the spatial self-adjustment patterns in the set of spatial self-adjustment patterns. Alternatively, the CSI-RS resource is not associated with a spatial self-adjustment pattern identifier. In some embodiments, at least one periodic or semi-persistent CSI-RS resource corresponding to the spatial self-adjustment pattern is associated with the same reporting time.

[0092] Through this solution, the reporting time domain resources corresponding to the periodic or semi-persistent CSI-RS resources corresponding to the spatial self-adjustment pattern can be determined.

[0093] In some embodiments, the periodic or semi-persistent CSI-RS resources corresponding to the at least one spatial self-adjustment pattern include CSI-RS resources corresponding to the spatial self-adjustment pattern within a time window, and the CSI-RS resources corresponding to the spatial self-adjustment pattern (or a set or subset of spatial self-adjustment patterns) within the time window are associated with a CSI reporting configuration, and the time window is a time window associated with the spatial self-adjustment pattern; Alternatively, (when the spatial self-adjustment type information indicates a second spatial self-adjustment type) at least one CSI report configuration is associated with at least one CSI-RS resource associated with the spatial self-adjustment pattern, and the at least one CSI report configuration is reported in the same time unit.

[0094] Here, for the second spatial self-adjustment type, each independent or separate CSI-RS resource associated with the spatial self-adjustment pattern, and at least one set of independent or separate CSI-RS resources associated with the spatial self-adjustment pattern, is associated with one CSI reporting configuration or multiple CSI reporting configurations, and the multiple CSI reporting configurations are reported in the same time unit. Preferably, the time unit can be a time slot or N time slots, where the value of N can be predefined by the protocol or configured by higher-layer signaling.

[0095] In some embodiments, the information transmission method of the embodiment of the present invention further includes: Obtain the time window indicated by the network-side device through RRC signaling or dynamic signaling; Alternatively, the time window is determined according to the time period occupied by the CSI-RS resources corresponding to the set of spatial self-adjustment patterns.

[0096] In the embodiment of the present invention, based on the time window indicated by the network device or the time window determined by the terminal itself, periodic or semi-persistent CSI-RS resources associated with the same reporting time can be determined.

[0097] In some embodiments, each spatial self-adjustment pattern associated with the same CSI reporting configuration corresponds to an independent (or separate) CSI reporting amount; Alternatively, multiple spatial self-adjustment patterns associated with the same CSI reporting configuration correspond to the same first CSI reporting amount, and the multiple spatial self-adjustment patterns correspond to independent second CSI reporting amounts.

[0098] In an embodiment of the present invention, when each spatial self-adjustment pattern associated with the same CSI reporting configuration corresponds to an independent (or separate) CSI reporting amount, different spatial self-adjustment patterns can be configured with different reporting amounts. For example, spatial self-adjustment type 1 configures PMI, while spatial self-adjustment type 2 may not configure PMI, which is beneficial for reducing configuration consumption.

[0099] When multiple spatial self-adjustment patterns associated with the same CSI reporting configuration correspond to the same first CSI reporting amount, and the multiple spatial self-adjustment patterns correspond to independent second CSI reporting amounts, the common reporting amount (i.e., the first CSI reporting amount) of the multiple spatial self-adjustment patterns can be uniformly configured, eliminating the need to configure each spatial self-adjustment pattern separately, thereby reducing configuration overhead.

[0100] In some embodiments, the spatial self-adjustment pattern information includes M spatial self-adjustment patterns out of N spatial self-adjustment patterns configured by the network-side device, where M≤N, and M and N are positive integers; The terminal measures the reference signal resources associated with the airspace self-adjustment indication information and reports the measurement results, including: The terminal measures the reference signal resources associated with the M spatial domain self-adjustment patterns and reports the M measurement results.

[0101] In an embodiment of the present invention, a terminal measures and reports M of N spatial self-adjustment patterns according to an instruction of a network device, thereby reducing CSI reporting consumption.

[0102] In some embodiments, the base station uses RRC signaling or dynamic signaling to indicate the M spatial domain self-adjustment patterns corresponding to the CSI reported by the terminal. Alternatively, the terminal itself determines the CSI to be reported.

[0103] In some embodiments, the terminal reports M measurement results, including: The terminal reports the first measurement result and the relative information of the measurement result; The first measurement result is a measurement result corresponding to the first spatial domain self-adjustment pattern among the M measurement results; The measurement result relative information refers to relative information between the second measurement result and the first measurement result, including a difference or relative value between a measurement value corresponding to the second measurement result and a measurement value corresponding to the first measurement result. The second measurement result is a measurement result corresponding to the second spatial domain self-adjustment pattern among the M measurement results.

[0104] For example, the terminal reports the CSI corresponding to the first spatial domain self-adjustment pattern, and feeds back relative information (such as relative value) of the CSI corresponding to the second spatial domain self-adjustment pattern and the CSI corresponding to the first spatial domain self-adjustment pattern.

[0105] Here, by reporting the first measurement result and the relative information of the measurement result, the consumption of reporting the measurement result is further reduced.

[0106] The above-mentioned solution 2 is described below with reference to specific embodiments.

[0107] (1) The spatial self-adjustment pattern corresponds to the CSI-RS resource; The base station configures a spatial self-adjustment pattern / mode set (a set / group of spatial self-adjustment patterns / modes) for the UE using RRC signaling / dynamic signaling. In some embodiments, the protocol predetermines that the self-adjustment pattern / mode group is associated with the first CSI-RS resource; in some embodiments, RRC signaling explicitly configures the first CSI-RS resource and the spatial self-adjustment pattern / mode group associated with the first CSI-RS resource; In some embodiments, the spatial self-adjustment pattern index corresponding to the first CSI-RS resource is the lowest / highest index value in the set of spatial self-adjustment patterns, or the CSI-RS resource is not associated with the spatial self-adjustment pattern index, i.e., the first resource is not included in the CSI-RS resources associated with the spatial self-adjustment pattern; or the base station configures at least one periodic / semi-persistent CSI-RS resource for the UE (preferably, each CSI-RS resource can be a different time domain resource, a different frequency domain resource, or both), and each CSI-RS resource corresponds to a spatial self-adjustment pattern. The set of spatial self-adjustment patterns can be based on type 1 or type 2 spatial self-adjustment patterns.

[0108] (2) Reporting time; The periodic / semi-persistent CSI-RS resource corresponding to at least one spatial self-adjustment pattern is associated with the same reporting time.

[0109] More specifically, each spatial self-adjustment pattern / mode in the set is associated with a different CSI-RS resource (e.g., a CSI-RS resource with a different time domain position, preferably a periodic or semi-continuous CSI-RS resource) and at least one CSI-RS resource corresponding to the spatial self-adjustment pattern / mode set or subset within the spatial self-adjustment time window (i.e., the above-mentioned time window) is associated with a report setting, i.e., a CSI report configuration (CSI-Report). Config); The time window is preferably explicitly configured by the base station using RRC signaling / dynamic signaling. The base station can use higher-layer signaling to configure the period and / or offset of the time window for periodic reporting. In some embodiments, the time window only includes CSI-RS resources corresponding to a portion or subset of a set of spatial self-adjustment patterns. In this case, the CSI-ReportConfig is associated with the subset of the set of spatial self-adjustment patterns, as shown in FIG5 (associated with the four spatial self-adjustment patterns identified as 1, 2, 3, and 4, i.e., associated with the set of spatial self-adjustment patterns), or, as shown in FIG6 , with the subset of the set of spatial self-adjustment patterns. Alternatively, the time window is determined by the UE, and the position of the time window is the time period occupied by the CSI-RS resources corresponding to the set of spatial self-adjustment patterns, for example, the time length occupied in the time domain by the actually transmitted CSI-RS resources corresponding to a set of spatial self-adjustment patterns. The starting position offset can serve as an implicit configuration of the time window.

[0110] Preferably, for type 2 spatial self-adjustment, the first CSI-RS resource and at least one spatial self-adjustment pattern associated therewith correspond to independent / separate CSI-RS resources, respectively. The above-mentioned CSI-RS resource set is associated with one CSI-ReportConfig or multiple CSI-ReportConfigs, but multiple CSI-ReportConfigs are reported in the same time unit, which can preferably be a slot or N slots. The value of N can be predefined by the protocol or configured by high-level RRC signaling.

[0111] (3) Report enhanced configuration; (3.1), according to the previous description, at least one spatial indication information, such as at least one CSI-RS transmission resource corresponding to a spatial self-adjustment pattern, can be associated with a report setting, i.e., a CSI-ReportConfig; Each spatial adaptation pattern independently or separately configures the CSI reporting amount. For example, it includes at least a spatial adaptation indicator, a spatial adaptation indicator (SAI), codebook information, and frequency domain information related to the reporting amount, such as subband / wideband information. The spatial adaptation indicator is preferably spatial adaptation pattern identification information, such as index information. The frequency domain information indicates whether the PMI and CQI reporting is associated with the wideband or subband reporting configuration.

[0112] This information transmission method offers the advantage of configuring different reporting amounts for different airspace self-adjustment patterns. For example, SAP0 can be configured with PMI, while SAP1 can be configured without PMI, thus reducing energy consumption. SAP0 can be configured with broadband reporting, while SAP1 can be configured with sub-band reporting to self-adjust to match different antenna shutdown patterns.

[0113] Specifically, an example of the signaling related to configuring the CSI reporting amount is as follows: CSI-ReportConfig ::= SEQUENCE { … SAP={SAP0, SAP1,…SAPN} reportQuantityCHOICE { SAP0 { sai-RI-PMI-CQI NULL, … reportFreqConfiguration SEQUENCE { cqi-FormatIndicator ENUMERATED { widebandCQI, subbandCQI} pmi-FormatIndicator ENUMERATED { widebandPMI, subbandPMI} csi-ReportingBand CHOICE {…} }, SAP1 { sai-RI-CQI NULL, … reportFreqConfiguration SEQUENCE { cqi-FormatIndicator ENUMERATED { widebandCQI, subbandCQI} pmi-FormatIndicator ENUMERATED { widebandPMI, subbandPMI} csi-ReportingBand CHOICE {…} }, SAP2 … }

[0114] (3.2) In some embodiments, multiple spatial self-adjustment patterns / modes associated with a reportconfig jointly configure a common first reporting quantity (i.e., the first CSI reporting quantity) and independently configure a second reporting quantity (i.e., the second CSI reporting quantity). The first reporting quantity includes precoding matrix indicator (PMI), Layer 1 reference signal received power (L1-RSRP), Layer 1 signal-to-noise and interference ratio (L1-SINR), etc. The second reporting quantity includes SAI, Channel Quality Indicator (CQI), bandwidth, subband indication information, Rank Indication (RI), Layer Indicator (LI), etc.

[0115] The beneficial effect of this solution is that it can identify the reporting amount of the public configuration and report it in a centralized manner to reduce PUCCH consumption. This solution is beneficial to the type 2 spatial self-adjustment solution because type 2 spatial self-adjustment only changes the beam width of the spatial beamforming but does not change the optimal beam direction. A common PMI can be used, and preferably, a common PMI can be agreed upon for all spatial self-adjustment patterns / modes based on the second spatial self-adjustment (type 2 SA).

[0116] Specifically, an example of the signaling related to configuring the first reporting amount and the second reporting amount is as follows: CSI-ReportConfig ::= SEQUENCE { … SAP={SAP0, SAP1,…SAPN} reportQuantityCHOICE { common PMI L1-RSRP L1-SINR } SAP0 { sai-RI-CQI NULL, … reportFreqConfiguration SEQUENCE { cqi-FormatIndicator ENUMERATED { widebandCQI, subbandCQI} pmi-FormatIndicator ENUMERATED { widebandPMI, subbandPMI} csi-ReportingBand CHOICE {…} }, SAP1 { sai-RI-CQI NULL, … reportFreqConfiguration SEQUENCE { cqi-FormatIndicator ENUMERATED { widebandCQI, subbandCQI} pmi-FormatIndicator ENUMERATED { widebandPMI, subbandPMI} csi-ReportingBand CHOICE {…} }, SAP2 … }

[0117] (3.3) In some embodiments, the base station configures N spatial self-adjustment patterns / modes using RRC signaling, and the base station instructs the UE using RRC signaling or dynamic signaling to use M spatial self-adjustment patterns / modes corresponding to the CSI that needs to be reported in one CSI-ReportConfig / multiple CSI-ReportConfigs, where M≤N, and M and N are positive integers.

[0118] In some embodiments, the base station configures N spatial self-adjustment patterns using RRC signaling. The base station also uses RRC signaling and / or dynamic signaling to indicate to the UE the number of sub-CSIs to be reported in a CSI-Report Config or multiple CSI-Report Configs, or the number M of sub-CSI reports associated with each CSI-Report Config. Each sub-CSI is associated with a spatial self-adjustment pattern. Alternatively, the UE determines the M sub-CSIs to be reported based on the base station configuration and selects M of the N spatial self-adjustment patterns to report. This is dependent on UE implementation.

[0119] It is optimal for the UE to determine the CSI to be reported. However, if the base station uses signaling to configure at least one CSI to be reported, it is beneficial for the base station to obtain the best reporting from the perspective of network energy saving. This is because the base station obtains reporting information related to multiple UEs, rather than the optimal reporting of a single UE.

[0120] (3.4) When a UE reports M CSIs associated with a set of spatial self-adjustment patterns, the UE preferably reports the CSI corresponding to the first spatial self-adjustment pattern or the first CSI-RS resource, and the UE reports the relative value between the CSI corresponding to the second spatial self-adjustment pattern and the CSI corresponding to the first spatial self-adjustment pattern. Preferably, the base station configures the first spatial self-adjustment pattern or the first CSI-RS resource for which complete CSI is to be reported using RRC signaling. In some embodiments, the UE itself determines the first spatial self-adjustment pattern or the first CSI-RS resource.

[0121] Option 3: Update of air domain self-adjustment and / or power domain self-adjustment.

[0122] In some embodiments, the information transmission method further includes: The terminal obtains second indication information, where the second indication information includes at least one of air domain self-adjustment update information and power domain self-adjustment update information; The terminal reports channel state information CSI or stops CSI reporting according to the second instruction information.

[0123] In the embodiment of the present invention, the spatial self-adjustment information and / or the power self-adjustment information can be updated through the second indication information.

[0124] In some embodiments, the terminal obtains airspace self-adjustment update information, including: Acquiring airspace self-adjustment update information through first dynamic signaling, where the first dynamic signaling includes first downlink control information (DCI) or a first media access control control element (MAC CE).

[0125] In some embodiments, the airspace self-adjustment update information includes at least one of the following: airspace self-adjustment start information or airspace self-adjustment de-start information; Subset information of the set of spatial self-adjustment patterns.

[0126] The above-mentioned airspace self-adjustment update information can be used to start or stop the airspace self-adjustment information, and then determine whether to report CSI.

[0127] In some embodiments, the first DCI satisfies at least one of the following: Scrambling is performed using a first Radio Network Temporary Identity (RNTI), where the first RNTI includes an RNTI specific to network energy saving, an RNTI specific to airspace energy saving, or an RNTI specific to airspace energy saving and power domain energy saving. That is, the airspace self-adjustment update information can be determined by scrambling the first DCI. The first DCI includes DCI format 0_1 ​​or DCI format 0_2; The first field of the first DCI carries spatial self-adjustment update information or non-spatial self-adjustment update information; for example, the first field may be a CSI request field; and the terminal can determine, through the first field, whether the first DCI indicates spatial self-adjustment update information or non-spatial self-adjustment update information; The first predefined code point (or first predefined field) of the first DCI is associated with verification information of the spatial self-adjustment activation information; for example, the first predefined field includes a Hybrid Automatic Repeat reQuest (HARQ) process number field and a Redundancy Version (RV) field. Thus, the first predefined code point can be used to verify the spatial self-adjustment activation information to determine whether the spatial self-adjustment activation information is valid. The second predefined code point (or second predefined field) of the first DCI is associated with verification information for the spatial self-adjustment deactivation information; for example, the second predefined field includes: a HARQ process number field, a modulation and coding scheme (MCS) field, a resource block assignment field, and a redundancy version field. Thus, the second predefined code point can be used to verify the spatial self-adjustment deactivation information to determine whether the spatial self-adjustment deactivation information is valid deactivation information. The second field of the first DCI is used to indicate whether spatial self-adjustment is supported. This second field can be a newly added field, such as an spatial self-adjustment indication field, which uses two 1-bit code points to indicate whether spatial self-adjustment is supported or not. In this embodiment of the present invention, the terminal detects the DCI scrambled by the first RNTI and further detects the verification information. If the verification information also passes verification, the terminal performs relevant operations based on the indication of the spatial self-adjustment activation or deactivation indication information.

[0128] In some embodiments, the code point carried by the first field corresponds to different trigger states, each trigger state is associated with at least one CSI report configuration, and each CSI report configuration is associated with at least one spatial self-adjustment pattern.

[0129] Here, the associated spatial self-adjustment pattern can be determined by the trigger state corresponding to the code point carried by the first field.

[0130] In some embodiments, when the CSI reporting configuration associated with the first field belongs to a first CSI reporting configuration set, the first field is used to indicate activation information associated with spatial self-adjustment or deactivation information associated with spatial self-adjustment; Alternatively, when the CSI reporting configuration associated with the first field belongs to the second CSI reporting configuration set, the first field is used to indicate semi-continuous reporting not associated with airspace self-adjustment (which may also be described as semi-continuous reporting not associated with airspace self-adjustment) activation information or semi-continuous reporting activation information not associated with airspace self-adjustment; Alternatively, when the CSI-RS resource associated with the first field belongs to the first CSI-RS resource set, the first field is used to indicate activation information associated with spatial self-adjustment or deactivation information associated with spatial self-adjustment; Alternatively, when the CSI-RS resource associated with the first field belongs to the second CSI-RS resource set, the first field is used to indicate semi-continuous reporting deactivation information associated with non-spatial self-adjustment or semi-continuous reporting activation information associated with non-spatial self-adjustment.

[0131] In this embodiment of the present invention, the base station divides the CSI-ReportConfig (CSI reporting configuration) identifier (ID) into two subsets (i.e., a first CSI reporting configuration set and a second CSI reporting configuration set) and configures them for the UE using RRC signaling. The first CSI-ReportConfig set corresponds to enabling / deactivating spatial self-adjustment, while the second CSI-ReportConfig set corresponds to enabling / deactivating non-spatial self-adjustment.

[0132] Through the relationship between the CSI reporting configuration associated with the first field and the two CSI reporting configuration sets, it is possible to implicitly determine whether the first field is used to indicate activation information or deactivation information of an airspace self-adjustment association, or to indicate deactivation information of semi-continuous reporting of a non-airspace self-adjustment association or activation information of semi-continuous reporting of a non-airspace self-adjustment association; Alternatively, through the relationship between the CSI-RS resource associated with the first field and the two CSI-RS resource sets, it can be determined whether the first field is used to indicate startup information associated with airspace self-adjustment or deactivation information associated with airspace self-adjustment, or to indicate semi-continuous reporting deactivation information associated with non-airspace self-adjustment or semi-continuous reporting startup information associated with non-airspace self-adjustment.

[0133] In some embodiments, the terminal obtains the information and / or corresponding functions of the above two sets according to RRC signaling configuration or agreement.

[0134] In some embodiments, the terminal self-adjusts and updates information according to the airspace, reports channel state information (CSI), or stops reporting CSI, including: When the trigger state indicated by the first DCI belongs to a first trigger state set or is associated with a third CSI-RS resource set, the terminal performs aperiodic CSI reporting related to spatial self-adjustment; and / or, when the trigger state indicated by the first DCI belongs to a second trigger state set or is associated with a fourth CSI-RS resource set, the terminal performs aperiodic CSI reporting related to non-spatial self-adjustment, the first trigger state set and the second trigger state set are two different trigger state sets (configured by the network or agreed upon), and the third CSI-RS resource set and the fourth CSI-RS resource set are two different CSI-RS resource sets (configured by the network or agreed upon); Alternatively, when the third field or target bit in the first DCI indicates non-periodic CSI reporting related to spatial self-adjustment, the terminal performs non-periodic CSI reporting related to spatial self-adjustment; and / or, when the third field or target bit in the first DCI indicates non-periodic CSI reporting related to non-spatial self-adjustment, the terminal performs non-spatial self-adjustment-related non-spatial self-adjustment.

[0135] Here, the corresponding terminal operation can be implicitly determined by the relationship between the trigger state indicated by the DCI and the trigger state set, or the relationship between the trigger state indicated by the DCI and the CSI-RS resource set.

[0136] In some embodiments, at least one spatial self-adjustment pattern is associated with at least one periodic CSI-RS resource and associated with at least one periodic CSI reporting configuration; The terminal self-adjusts and updates information according to the airspace, and reports channel status information (CSI) or stops CSI reporting, including: Reporting CSI in a first resource based on the spatial self-adjustment startup information; or stopping reporting CSI in a first resource based on the spatial self-adjustment startup information; wherein the first resource is a resource corresponding to the periodic CSI report configuration; And / or, based on the spatial self-adjustment startup information, reporting CSI in the second resource; or, based on the spatial self-adjustment de-activation information, stopping reporting CSI in the second resource, where the second resource is the resource corresponding to the periodic CSI report configuration associated with the subset information of the set of spatial self-adjustment patterns.

[0137] In an embodiment of the present invention, when at least one spatial self-adjustment pattern is associated with at least one periodic CSI-RS resource and at least one periodic CSI reporting configuration, the resources corresponding to the periodic CSI reporting configuration are used as CSI reporting resources, or the resources corresponding to the periodic CSI reporting configuration associated with the subset information of the set of self-adjustment patterns are determined as reporting resources.

[0138] In some embodiments, at least one spatial self-adjustment pattern is associated with at least one periodic CSI-RS resource or semi-persistent CSI-RS resource, and at least one of the spatial self-adjustment patterns is associated with at least one semi-persistent CSI reporting configuration; The terminal self-adjusts and updates information according to the airspace, and reports channel status information (CSI) or stops CSI reporting, including: According to the spatial self-adjustment start information, semi-continuous CSI reporting is started on the third resource, or semi-continuous CSI reporting is started on the third resource, where the third resource is a resource corresponding to the semi-continuous CSI report configuration associated with the subset information of the set of the spatial self-adjustment pattern.

[0139] In an embodiment of the present invention, for a situation where at least one spatial self-adjustment pattern is associated with at least one periodic CSI-RS resource or semi-persistent CSI-RS resource, and at least one of the spatial self-adjustment patterns is associated with at least one semi-persistent CSI reporting configuration, resources corresponding to the semi-persistent CSI reporting configuration associated with subset information of a set of spatial self-adjustment patterns are determined as CSI reporting resources.

[0140] In some embodiments, at least one spatial self-adjustment pattern is associated with at least one periodic CSI-RS resource, semi-persistent CSI-RS resource, or aperiodic CSI-RS resource, and at least one of the spatial self-adjustment patterns is associated with at least one aperiodic CSI reporting configuration; The terminal adjusts and updates information based on the airspace and reports channel status information (CSI), including: According to the spatial self-adjustment update information, aperiodic CSI reporting is performed on a fourth resource, where the fourth resource is a resource corresponding to the aperiodic CSI report configuration associated with the subset information of the spatial self-adjustment pattern set.

[0141] In an embodiment of the present invention, for a situation where at least one spatial self-adjustment pattern is associated with at least one periodic CSI-RS resource, semi-persistent CSI-RS resource, or aperiodic CSI-RS resource, and at least one of the spatial self-adjustment patterns is associated with at least one aperiodic CSI reporting configuration, resources corresponding to the aperiodic CSI reporting configuration associated with subset information of a set of spatial self-adjustment patterns are determined as CSI reporting resources.

[0142] In some embodiments, the power domain self-adjustment update information is associated with the first set or the second set; Wherein, the first set is a subset of the first power offset value set, and the second set is a subset of the second power offset set; The first power offset value set is a set of CSI-RS and physical downlink shared channel (Physical Downlink Shared Channel, PDSCH) power offset values, and the second power offset value set is a set of SSB and CSI-RS power offset values.

[0143] In some embodiments, the power domain self-adjusts and updates information, including: Power domain network energy saving startup information or power domain network energy saving de-activation information, or including power domain network energy saving non-periodic reporting trigger information.

[0144] The power domain network energy saving start information or the power domain network energy saving start information or the power domain network energy saving non-periodic reporting trigger information can trigger the terminal to report or stop reporting CSI.

[0145] In some embodiments, the power domain self-adjustment update information is associated with a subset of the first set of power offset values ​​or a subset of the second set of power offset values.

[0146] In some embodiments, the terminal obtains power domain self-adjustment update information, including: The power domain self-adjustment update information is obtained through the second dynamic signaling, where the second dynamic signaling includes the second downlink control information DCI or the second media access control element MAC CE.

[0147] In some embodiments, the second DCI satisfies at least one of the following: Using a second radio network temporary identifier RNTI for scrambling, the second RNTI including a power domain network energy-saving exclusive RNTI, or an air domain and power domain energy-saving exclusive RNTI; The second DCI includes DCI format 0_1 ​​or DCI format 0_2; The code points carried by the second DCI correspond to different trigger states, each trigger state is associated with at least one CSI report configuration, and each CSI report configuration is associated with at least one power domain self-adjustment pattern; The fourth field in the second DCI carries the power domain self-adjustment update information or the spatial domain self-adjustment update information; the fourth field may be an existing field in the DCI, such as a CSI request field, or a newly added field; in some embodiments, the position of the field in the DCI may be configured for the UE via RRC signaling; in some embodiments, the codepoints / bit sets corresponding to the power domain self-adjustment and / or spatial domain self-adjustment indications may be configured via RRC signaling, for example, a first codepoint or bit set is used to indicate spatial domain self-adjustment activation / deactivation information, and a second codepoint or bit set is used to indicate power domain activation or deactivation information; The third predefined code point (or the third predefined code point sub-segment) of the second DCI is associated with the verification information of the power domain network energy saving activation information; a verification information relationship between the fourth predefined code point (fourth predefined subsegment) of the second DCI and the power domain network energy saving deactivation information; The target indication field of the second DCI is used to indicate that the information carried by the fourth field is power domain self-adjustment update information or spatial domain self-adjustment update information.

[0148] In an embodiment of the present invention, the terminal detects the DCI scrambled by the power domain RNTI and further detects the verification information. If the verification information also passes the verification, the terminal performs relevant operations according to the instructions of the power domain (or power domain energy saving) activation or deactivation indication information.

[0149] After successfully receiving the power domain activation or deactivation information, the terminal will feedback the corresponding CSI. If the UE receives power domain deactivation signaling, it will stop measuring and feedback the corresponding CSI according to the deactivation signaling instructions.

[0150] In some embodiments, the terminal self-adjusts and updates information according to the power domain to report channel status information CSI or stop reporting CSI, including: The terminal reports CSI according to the power domain network energy saving start information or the power domain network energy saving aperiodic reporting trigger information; Alternatively, the terminal starts information based on power domain network energy saving and stops CSI reporting.

[0151] In an embodiment of the present invention, the terminal determines whether CSI reporting is required based on power domain network energy saving activation information or deactivation information.

[0152] The above-mentioned solution three is described below with reference to specific embodiments.

[0153] Example 1: Dynamic signaling updates airspace self-adjustment signaling mechanism: The base station uses dynamic signaling DCI or MAC CE to indicate airspace self-adjustment update information: Implementation 1: 1) The base station configures a set of spatial self-adjustment patterns for the UE using RRC signaling, where at least one of the spatial self-adjustment patterns is associated with at least one periodic CSI-RS resource and at least one periodic CSI report setting; 2) The base station side sends an airspace self-adjustment update indication using dynamic signaling DCI or MAC-CE. In some embodiments, the airspace self-adjustment update indication may include airspace self-adjustment activation / deactivation information and / or a subset of airspace self-adjustment patterns / mode groups; 3) The UE receives the airspace self-adjustment update information carried by dynamic signaling; 3.1) After receiving the spatial self-adjustment start information carried in the spatial self-adjustment update indication, the UE shall report the CSI on the corresponding PUSCH / PUCCH according to the periodic CSI reporting setting configuration. If the spatial self-adjustment information also carries "spatial self-adjustment pattern / mode group subset information", the UE shall report the CSI on the corresponding PUSCH / PUCCH according to the periodic CSI reporting setting configuration associated with the "spatial self-adjustment pattern / mode group subset information"; 3.2) Upon receiving the "Aerial Self-Adjustment Deactivation Information" carried in the Aerial Self-Adjustment Update Indication, the UE shall cease reporting CSI on the PUSCH / PUCCH corresponding to the periodic CSI reporting setting. If the Aerial Self-Adjustment Information also carries "Aerial Self-Adjustment Pattern / Mode Group Subset Information," the UE shall cease reporting CSI on the PUSCH / PUCCH corresponding to the periodic CSI reporting setting associated with the "Aerial Self-Adjustment Pattern / Mode Group Subset Information."

[0154] Implementation 2: 1) The base station configures a set of spatial self-adjustment patterns for the UE using RRC signaling, where at least one of the spatial self-adjustment patterns is associated with at least one periodic / semi-persistent CSI-RS resource and at least one semi-persistent CSI reporting setting; 2) The base station side sends spatial self-adjustment update information using dynamic signaling DCI or MAC-CE. In some embodiments, the spatial self-adjustment update information preferably includes spatial self-adjustment activation / deactivation information; 3) The UE receives the airspace self-adjustment update information carried by dynamic signaling; 3.1) Upon receiving the "Aerospace Self-Adjustment Start Information" carried in the ASA Update Information, the UE shall initiate semi-persistent CSI reporting on the PUCCH / PUSCH corresponding to the CSI repot setting associated with the "Aerospace Self-Adjustment Pattern / Pattern Group Subset Information" corresponding to the ASA Start Information; 3.2) After receiving the "Asia-wide Self-Adjustment Deactivation Information" contained in the ASA Update message, the UE shall initiate semi-persistent CSI reporting on the PUCCH / PUSCH corresponding to the CSI repot setting associated with the "Asia-wide Self-Adjustment Pattern / Pattern Group Subset Information" corresponding to the activation signaling in 3.1).

[0155] Implementation 3: 1) The base station configures a set of spatial self-adjustment patterns for the UE using RRC signaling, where at least one of the spatial self-adjustment patterns is associated with at least one periodic, semi-persistent, or aperiodic CSI-RS resource and at least one aperiodic CSI reporting setting; 2) The base station side uses dynamic signaling DCI to send spatial self-adjustment update information. In some embodiments, the spatial self-adjustment update information may include spatial self-adjustment activation / deactivation information. 3) The UE receives the airspace self-adjustment update information carried by dynamic signaling; 3.1) Upon receipt of the airspace self-adjustment update message carrying the airspace self-adjustment update information, the UE shall perform a one-time aperiodic CSI report on the PUSCH corresponding to the CSI repot setting associated with the airspace self-adjustment pattern / mode group subset information corresponding to the airspace self-adjustment information.

[0156] Example 2: Activation / deactivation mechanism: As described in Example 1, a DCI-based spatial self-adjustment update mechanism is described. A base station can trigger a first update operation for spatial self-adjustment via dynamic activation and / or deactivation signaling, or a second update operation for spatial self-adjustment information via dynamic signaling. Preferably, the first update operation corresponds to semi-continuous measurement / reporting, and the second update operation corresponds to aperiodic measurement / reporting. Specific design implementations are described below.

[0157] Implementation 1: An airspace self-adjustment activation / deactivation mechanism based on dynamic signaling (DCI), where the DCI (i.e., the first DCI) satisfies at least one of the following: a. The DCI is scrambled using a network energy-saving or spatial energy-saving RNTI, or a spatial, power, and energy-saving RNTI. Examples include the Network Energy Saving-RNTI (NES-RNTI), the Spatial Adaptation Pattern-RNTI (SAP-RNTI), and the Spatial Adaptation Mode-RNTI (SAM-RNTI). The above RNTIs are examples only and other methods are not excluded. The base station configures the UE with the network energy-saving RNTI using higher-layer signaling. b. The DCI preferably includes at least DCI format (format) 0_1, 0_2, the DCI does not exclude other DCI format, can be scheduled DCI can also be non-scheduled DCI; c. The airspace self-adjustment update information carried in the airspace self-adjustment start signaling is carried in the CSI request field of the DCI. The code points carried in the CSI request field in the DCI correspond to different trigger states. Each trigger state can be associated with at least one CSI-ReportConfig, and each CSI-ReportConfig is associated with at least one airspace self-adjustment pattern. d. For the activation signaling and deactivation signaling verification information corresponding to the predefined word field and predefined code point value of the DCI, respectively, an example is described as follows: when the information value carried by the DCI satisfies the constraints of Table 1, the activation DCI is valid activation signaling. If the information value carried by the DCI satisfies the constraints of Table 2, the activation DCI is valid deactivation signaling.

[0158] Table 1 DCI format 0_1 / 0_2 Number of HARQ processes Set to all '0's RV Set to all '0's

[0159] Table 2 DCI format 0_1 / 0_2 Number of HARQ processes Set to all '0's MCS Set to all 1s Resource block allocation If the upper layer only configures RA type 0, set it to all "0"; If the upper layer is configured with only RA type 1, set it to all "1"; If the upper layer configures dynamic switching between RA types 0 and 1, then if the MSB is "0", it is set to all "0"; otherwise, it is set to all "1"; For DCI 0_1, if the higher layer configures RA type 2, if µ=0, set to all '1'; if µ=1, set to all '0' RV Set to all '0's

[0160] Implementation 2: An airspace self-adjustment activation / deactivation mechanism based on dynamic signaling (DCI), where the DCI (i.e., the first DCI) satisfies at least one of the following: a. The DCI preferably includes at least DCI format 0_1, 0_2 and the DCI is scrambled using Semi-Persistent CSI RNTI (SP-CSI-RNTI); b. DCI adds a new field for indicating airspace self-adjustment, for example, two code points of 1 bit, used to indicate whether airspace self-adjustment is supported or not.

[0161] In this implementation, if the UE receives the first bit of the airspace self-adjustment indication field, it indicates that the CSI request field carries airspace self-adjustment activation / deactivation indication information; if the airspace self-adjustment indication field is the second bit, the CSI request field carries non-airspace self-adjustment semi-persistent CSI report activation / deactivation indication information.

[0162] Rel-18 UE supports CSI reporting activation / deactivation for both airspace self-adjustment and non-airspace self-adjustment according to base station DCI instructions.

[0163] Implementation 3: 1) The base station divides the CSI-ReportConfig ID (or CSI-RS resource set) into two subsets and configures them for the UE using RRC signaling; 2) The first CSI-ReportConfig set is associated with spatial self-adjustment activation / deactivation, and the second CSI-ReportConfig set is associated with non-spatial self-adjustment activation / deactivation (or the first CSI-RS resource set is associated with spatial self-adjustment activation / deactivation, and the second CSI-RS resource set is associated with non-spatial self-adjustment activation / deactivation). Non-spatial self-adjustment here means that spatial self-adjustment is not supported, such as legacy Rel-15, Rel-16, and Rel-17 spatial domain multiplexing. The UE obtains information and / or corresponding functions of these two subsets based on base station RRC signaling configuration or through agreed methods. 3) The UE detects the CSI request field of the DCI bearer. If the CSI-Report Config associated with the CSI request field belongs to the first CSI-Report Config subset, the CSI request field is used to indicate the activation / deactivation of airspace self-adjustment. If the CSI-Report Config associated with the CSI request field belongs to the second CSI-Report Config subset, the CSI request field is used to indicate the activation / deactivation of non-airspace self-adjustment (or normal / legacy R15 / R16 / R17 airspace activation / deactivation).

[0164] Alternatively, if the CSI-RS resource associated with the CSI request field belongs to the first CSI-RS resource set, the CSI request field is used to indicate spatial self-adjustment activation / deactivation; if the CSI-RS resource associated with the CSI request field belongs to the second CSI-RS resource set, the CSI request field is used to indicate non-spatial self-adjustment activation / deactivation (or normal / legacy R15 / R16 / R17 spatial self-adjustment activation / deactivation).

[0165] Implementation 4: The above implementations 1-3 describe the dynamic activation / deactivation mechanism corresponding to the first update operation. For the case where only dynamic signaling is used to indicate the spatial self-adjustment update (at least there is no deactivation signaling, and the dynamic trigger signaling is different from the dynamic activation signaling), the following mechanism can be used. When the dynamic signaling DCI indicates the second spatial self-adjustment update, in some embodiments: The base station uses RRC signaling to configure a first trigger state set, or a first trigger state set and a second trigger state set, for the UE. The first trigger state set is associated with a first measurement / reporting set, namely, a spatial self-adjustment pattern set, and the second trigger state set is associated with a second measurement / reporting set, namely, an aperiodic CSI-RS resource / reporting set not associated with spatial self-adjustment, corresponding to legacy R15 / R16 / R17 aperiodic measurement and reporting unrelated to spatial self-adjustment. The UE determines whether to perform spatial self-adjustment or aperiodic reporting unrelated to spatial self-adjustment based on the trigger state set indicated by dynamic signaling. More specifically, if the trigger state belongs to the first trigger state set, the UE performs aperiodic reporting related to spatial self-adjustment (first CSI measurement / reporting); otherwise, it performs legacy aperiodic CSI measurement / reporting (second CSI measurement / reporting).

[0166] Alternatively, the base station configures a first CSI-RS resource set / CSI reporting set and / or a second CSI-RS resource set / CSI reporting set for the UE using RRC signaling, wherein the first CSI-RS resource set / CSI reporting set is associated with a first measurement / reporting set, i.e., a spatial self-adjustment pattern / pattern set, and the second CSI-RS resource set / CSI reporting set is associated with a second measurement / reporting set, i.e., an aperiodic measurement / reporting operation unrelated to spatial self-adjustment, such as legacy R15 / R16 / R17 aperiodic measurement and reporting unrelated to spatial self-adjustment. If the UE associates with the first CSI-RS resource set / CSI reporting set according to a trigger state indicated by dynamic signaling, the UE performs aperiodic reporting related to spatial self-adjustment (first CSI measurement / reporting); otherwise, the UE performs legacy aperiodic CSI measurement / reporting (second CSI measurement / reporting).

[0167] In some embodiments, the protocol specifies adding a single bit to the scheduling DCI to indicate whether the CSI request field carries information related to aperiodic CSI measurement / reporting (first CSI measurement / reporting) for spatial domain self-adjustment or legacy aperiodic CSI measurement / reporting (second CSI measurement / reporting). The UE determines whether to perform the first or second CSI measurement / report based on the newly added DCI bit and the CSI request field.

[0168] In some embodiments, the protocol stipulates that a new field is added to the DCI to indicate non-periodic CSI measurement / reporting related to spatial self-adjustment (first CSI measurement / reporting), that is, the first field indicates spatial self-adjustment related measurement / reporting; and the CSI request field is used to indicate legacy non-periodic CSI measurement / reporting.

[0169] Example 3: Power domain network energy saving solution.

[0170] In principle, the solution of the second embodiment can also be applied to the power domain network energy saving solution. Specifically: 1) The base station uses RRC signaling to configure N ≥ 1 sets of CSI-RS and PDSCH power offset values, namely the aforementioned first power offset value set: {powerControlOffset_1, powerControlOffset_2, …powerControlOffset_N}, or configure N ≥ 1 sets of SSB and CSI-RS power offset values, namely the aforementioned second power offset value set: {powerControlOffsetSS_1, powerControlOffsetSS_2, …powerControlOffsetSS_N}, for a CSI-RS resource (preferably a periodic / semi-persistent CSI-RS resource) or a spatial / power domain self-adjustment pattern associated with a CSI resource; 2) The base station sends DCI / MAC-CE-based power domain network energy saving activation / deactivation signaling, where the power self-regulation update information includes power domain network energy saving activation / deactivation information. Preferably, the power self-regulation update information is associated with a subset of the first power offset value set or a subset of the second power offset value set configured in the previous step.

[0171] Implementation 1: 2.1) The DCI is scrambled using a network-specific energy conservation or power-domain-specific energy conservation (optimal solution), or an RNTI specific to both the airspace, power, and network energy conservation, such as the NES-RNTI, the Power Domain Adaptation-RNTI (PA-RNTI), or the SPA-RNTI. These RNTIs are examples only and other methods are not excluded. The base station configures the UE with this network-specific energy conservation RNTI using higher-layer signaling. 2.2) The DCI preferably includes at least DCI format 0_1, 0_2, of course, does not exclude other DCI format, the DCI can be a scheduling DCI can also be a non-scheduling DCI; 2.3.1) The power domain self-regulation activation / deactivation information carried in the power self-regulation update information is implemented by reusing existing fields in the DCI, for example, reusing the CSI request field. Preferably, if a dedicated RNTI for power domain network energy conservation is used in step 2.1), the power domain network energy conservation activation / deactivation signaling can reuse the code points carried in the CSI request field in the UL grant DCI. The code points correspond to different trigger states. Each trigger state can be associated with at least one CSI-ReportConfig, and each CSI-ReportConfig is associated with at least one power self-regulation information, namely, a power offset value or a power offset value subset. The power offset can be powerControlOffsetSS (i.e., an offset of the CSI-RS transmit power relative to the ss-PBCH-Block power) or powerControlOffset (i.e., the power offset from the non-zero power NZP CSI-RS RE to the PDSCH RE).

[0172] 2.3.2 In addition to reusing the CSI request field to indicate the power domain activation / deactivation indication as described in 2.3.1, in some embodiments, a new field is added to the DCI to carry power domain activation / deactivation indication information. For example, a new field for indicating spatial and power domain self-adjustment information is added to the DCI. The base station explicitly or implicitly configures at least one code point / bit set for the UE via RRC signaling. RRC signaling configures the position of this field in the DCI and the code point / bit set corresponding to the power domain, or the power domain and spatial domain self-adjustment indication, for the UE. Preferably, two code points / bit sets A and B are configured, wherein the first code point / bit set is used to indicate spatial domain self-adjustment indication information, such as spatial domain self-adjustment activation / deactivation information, and the second code point / bit set is used to indicate power domain self-adjustment indication information, such as power domain self-adjustment activation / deactivation information. Table 3 below provides an example of the corresponding two bit sets.

[0173] Table 3 Airspace self-adjustment instructions Power domain self-adjustment indication

[0174] 2.4) The verification information for the power domain activation information / deactivation information corresponds to the predefined DCI word fields and predefined code point values, similar to Tables 1 and 2, and will not be repeated here; 2.5) After the UE detects the DCI scrambled by the power domain RNTI, in some embodiments, it further checks the verification field. If the verification field also passes the verification, it further parses the activation / deactivation signaling based on the indication of the power domain activation / deactivation information related field; 2.6) After the UE successfully receives the power domain dynamic activation signaling, it feeds back the corresponding CSI according to the instructions of the dynamic activation signaling. If the UE receives the power domain dynamic deactivation signaling, it stops measuring and feeding back the corresponding CSI according to the instructions of the deactivation signaling.

[0175] In some embodiments of the present invention, spatial / power domain self-adjustment update information may be sent during a DRX non-activation period. In this case, the corresponding non-scheduled DCI may need to be scrambled using a network energy-saving-related dedicated RNTI in some embodiments. The dynamic signaling carrying the spatial domain self-adjustment update information may be a scheduled DCI, a non-scheduled DCI, or a MAC-CE when sent during the activation period.

[0176] It should be noted that in embodiments of the present invention, for dynamic signaling-based spatial self-adjustment or power domain self-adjustment, the activation / deactivation (corresponding to semi-persistent reporting) of dynamic signaling can be UE-specific signaling, group-common signaling, or cell-specific signaling. For dynamic signaling-based spatial self-adjustment or power self-adjustment, in some embodiments, the dynamic trigger signaling (corresponding to aperiodic reporting) can be UE-specific signaling, group-common signaling, or cell-specific signaling.

[0177] The above-mentioned solution of the embodiment of the present invention first provides a method for jointly indicating Type 2 spatial adaptation and Type 1 and Type 2 spatial adaptation. Then, for the above-mentioned spatial self-adjustment indication, it proposes: an enhanced spatial self-adjustment time domain reporting time, an enhanced reporting quantity and reporting configuration method, and a compressed reporting consumption scheme. Furthermore, for the spatial self-adjustment indication, it proposes a related technical enhancement scheme for a spatial or power domain self-adjustment activation and deactivation mechanism based on dynamic signaling. The proposed spatial energy-saving technology can effectively support Type 1 and Type 2 NES energy-saving configurations, reducing feedback consumption. The proposed spatial or power domain self-adjustment activation and deactivation mechanism based on dynamic signaling can be compatible with related technologies to achieve more flexible MIMO transmission and spatial energy saving.

[0178] As shown in FIG7 , an embodiment of the present invention further provides an information transmission method, including: Step 701: A network-side device sends first indication information, where the first indication information includes spatial domain self-adjustment indication information and / or power domain self-adjustment indication information.

[0179] In some embodiments, the spatial self-adjustment indication information is associated with a reference signal resource, and the power domain self-adjustment indication information is associated with a reference signal resource. The spatial self-adjustment information may also be described as spatial antenna element self-adjustment indication information or spatial indication information. The reference signal resource may be a CSI-RS.

[0180] In this embodiment of the present invention, a network-side device sends first indication information, causing a terminal to measure the reference signal resources associated with the first indication information and report the measurement results. This solution allows the terminal to self-adjust and determine the reference signal resources to be measured and report the measurement results. This allows the network-side device to self-adjust and adjust antenna power or the activation and deactivation of antenna ports based on the measurement results, thereby reducing energy consumption at the base station.

[0181] In some embodiments, the airspace self-adjustment indication information includes at least one of the following: Spatial self-adjustment type information, which is used to indicate whether the spatial self-adjustment type is type 1 spatial adaptation or type 2 spatial adaptation; Antenna port array-related information, the antenna port array-related information including at least one of antenna port number information, antenna panel information, and antenna dimension information, the antenna dimension information including first dimension information (e.g., horizontal direction) and second dimension information (e.g., vertical direction) related to the antenna array; Channel State Information Reference Signal (CSI-RS) resource-associated power information; Transmission Configuration Indicator (TCI) status indication information, the TCI status indication information is used to indicate the transmission beam information.
