[0056] For ease of understanding, some contents involved in the embodiments of the present application are described below:

[0057] 1. Network energy saving

[0058] Traditional base stations mainly use on-site power off, time-controlled switches, and cell blocking to save energy, but these methods are relatively extensive and cannot take into account user perception. Entering the era of the fifth generation mobile communication technology (5G), 5G base stations use 64T64R large-scale array antennas and support larger bandwidths, which leads to higher energy consumption than 4G base stations. Secondly, the 5G frequency band is high and the coverage range of a single station is small. To achieve the coverage effect of the 4G network, the deployment scale of 5G base stations will be 2 to 3 times that of 4G base stations. The equipment consumes more power, the number of sites is more, and the power consumption will inevitably be greater. The excessive power consumption of 5G has become a pain point in current network operations. It is imperative to study the energy saving of 5G base station technology.

[0059] Base station energy saving can be divided into symbol shutdown, carrier shutdown, channel shutdown and deep sleep technology according to the implementation principle. Technical background of airspace energy saving: Massive multiple-input multiple-output (MIMO) consumes more energy due to the large number of antennas and corresponding RF devices. When the number of UEs in a cell is small, the capacity / coverage gain brought by mMIMO will be redundant. At this time, the network side can dynamically shut down some TxRUs to achieve the purpose of network energy saving, such as Figure 2 As shown, the TxRUs corresponding to some antenna units can be turned off to serve a small number of users. After turning off some TxRUs, the coverage of the beam will be weakened and the beam width will increase.

[0060] The power domain considers dynamically adjusting the power control offset (powerControlOffset) value of the CSI reference signal (CSI Reference Signal, CSI-RS) resource (Resource).

[0061] 2. If Figure 3 As shown in the figure, there are two ways to shut down the airspace:

[0062] Type I shutdown means that all TxRUs associated with a port will be shut down, so the number of ports will change before and after the shutdown.

[0063] Type II shutdown means that some TxRUs associated with a port are shut down, so the number of ports does not change before and after the shutdown.

[0064] 3. CSI reporting framework

[0065] CSI reporting configuration (CSI-ReportConfig) mainly includes the following contents:

[0066] CSI resource configuration (setting): At least one CSI resource for channel measurement needs to be configured;

[0067] Report configuration type (reportConfigType): indicates the time domain behavior of CSI reporting;

[0068] Report frequency domain configuration (reportFreqConfiguration) n: indicates the frequency domain behavior of CSI reporting, that is, broadband reporting or narrowband reporting;

[0069] Report content (reportQuantity): indicates the parameters included in the report, including none, cri-RI-PMI-CQI, cri-RI-i1, cri-RI-i1-CQI, cri-RI-CQI, cri-RSRP, ssb-Index-RSRP and cri-RI-LI-PMI-CQI;

[0070] Codebook configuration (codebookConfig): indicates the reported codebook type, which can be Type I or Type II.

[0071] Time restriction for channel measurements (timeRestrictionForChannelMeasurements): indicates whether the time domain of CSI measurement is restricted.

[0072] 4. Concept of sub-configuration CSI reporting or CSI reporting sub-configuration (sub-config CSI report)

[0073] A CSI report configuration contains multiple sub-configurations, each of which corresponds to a spatial adjustment pattern.

[0074] 5. Activate the Media Access Control (MAC) control element (CE) for semi-static CSI reporting

[0075] The current semi-static CSI reporting activation MAC CE is as follows Figure 4 shown.

[0076] The SP CSI reporting on PUCCHActivation / Deactivation MAC CE is identified by a MAC subheader with LCID asspecified. It has a fixed size of 16bits with following fields:

[0077] Serving Cell ID: This field indicates the identity of the Serving Cell for which the MAC CE applies. The length of the field is 5 bits;

[0078] Bandwidth Part (BWP) ID: This field indicates a UL BWP for which the MAC CE applies as the codepoint of the DCI bandwidth part indicator field as specified in TS 38.212[9]. The length of the BWP ID field is 2 bits;

[0079] The SP CSI reporting on PUCCH Activation / Deactivation MAC CE is identified by a MAC subheader with LCID as specified in Table 6.2.1-1. It has a fixed size of 16 bits with following fields:

[0080] Serving Cell ID: This field indicates the identity of the Serving Cell forwhich the MAC CE applies. The length of the field is 5 bits;

[0081] BWP ID: This field indicates a UL BWPfor which the MAC CE applies as the codepoint of the DCI bandwidth partindicator field as specified in TS 38.212[9]. The length of the BWP ID fieldis 2bits;

[0082] Si: This field indicates the activation / deactivation status of the semi-persistent CSI reporting configuration in ReportConfigToAddModList specified in TS 38.331 [5]. S0 refers to the reporting configuration that includes PUCCH resources for SP CSI reporting in the indicated BWP and has the lowest CSI ReportConfigId in the list with type set to semi-PersistentONPUCCH, S1 refers to the reporting configuration that includes PUCCH resources for SP CSI reporting in the indicated BWP and has the second lowest CSIReportConfig Id, and so on. If the number of reporting configurations in the list with type set to semi-PersistentONPUCCH in the indicated BWP is less than i+1, the MAC entity shall ignore the Si field. The Si field is set to 1 to indicate that the corresponding semi-persistent CSI reporting configuration should be activated.The Si field is set to 0 to indicate that the corresponding semi-persistent CSI report configuration i will be deactivated (Si: This field indicates the activation / deactivation status of the Semi-Persistent CSI report configuration within ReportConfigToAddModList as specified in TS 38.331 [5]. S0 refers to the report configuration which includes PUCCH resources for SP CSI reporting in the indicated BWP and has the lowest CSI-ReportConfigId within the list with type set to semiPersistentOnPUCCH, S1 to the report configuration which includes PUCCH resources for SP CSI reporting in the indicated BWP and has the second lowest CSI-ReportConfigId and so on. If the number of report configurations within the list with type set to semiPersistentOnPUCCH in the indicated BWP is less than i+1, the MAC entity shall ignore the Si field. The Si field is set to 1 to indicate that the corresponding Semi-Persistent CSI report configuration shall be activated. The Si field is set to 0 to indicate that the corresponding Semi-Persistent CSI report configuration i shall be deactivated);.

[0083] R: Reserved bit, set to 0 (R: Reserved bit, set to 0).

[0084] ServingcellId indicates the identifier of the serving cell of this MAC CE application; the length is 5 bits;

[0085] Si represents the status of the semi-static CSI reporting configuration in ReportConfigToAddModList, s0 refers to the CSI reporting configuration with the smallest CSI-ReportConfigId among all semi-static CSI reporting configurations, and so on; a value of 1 indicates that the semi-static CSI reporting configuration is activated, and 0 indicates that it is deactivated.

[0086] 6. Activate MAC CE with semi-static CSI-RS

[0087] like Figure 5 As shown, the non-periodic CSI reporting and the non-periodic CSI-RS Resource are triggered by two MAC CEs respectively. Among them, A / D indicates activation or deactivation, a value of 1 indicates activation, and a value of 0 indicates deactivation. M indicates whether the SP-CSI-IM exists, a value of 1 indicates existence, and a value of 0 indicates non-existence. TCI state ID0 indicates the TCI stateID of the first CSI resource in the CSI resource set.

[0088] 7. Activate triggerState for aperiodic CSI reporting

[0089] The triggerState can be represented by CSI-AperiodicTriggerStateList as follows:

[0090]

[0091] Each CSI-AperiodicTriggerStateList consists of up to 128 CSI-AperiodicTriggerStates (maxNrOfCSI-AperiodicTrigger is 128), and each CSI-AperiodicTriggerState contains up to 16 CSI-AssociatedReportConfigInfos (maxNrOfReportConfigPerAperiodicTrigger is 16). Each CSI-AssociatedReportConfigInfo must contain 1 reportConfigId, corresponding to 1 CSI-ReportConfigId, through which it is associated with the corresponding CSI-ReportConfig. Each CSI-AssociatedReportConfigInfo must also contain 1 resourcesForChannel, where each resourcesForChannel contains 1 nzp-CSI-RS or 1 csi-SSB-ResourceSet. The resourceSet in nzp-CSI-RS indicates the NZP CSI-RS resource set (NZP-CSI-RS-ResourceSet) used for channel measurement, and the csi-SSB-ResourceSet indicates the SSB resource set (CSI-SSB-ResourceSet) used for channel measurement. In addition to resourcesForChannel, each CSI-AssociatedReportConfigInfo can also contain 1 csi-IM-ResourcesForInterference and / or 1 nzp-CSI-RS-ResourcesForInterference (both Optional), the former indicating the CSI-IM resource set (CSI-IM-ResourceSet) used for interference measurement, and the latter indicating the NZP CSI-RS resource set (NZP-CSI-RS-ResourceSet) used for interference measurement.

[0092] 8. Activate the trigger state (triggerState) of semi-static CSI reporting (similar to aperiodic):

[0093] The CSI-SemiPersistentOnPUSCH-TriggerStateList IE is used to configure the UE with one or more trigger states of PUSCH-based semi-persistent CSI reports, namely CSI-SemiPersistentOnPUSCH-TriggerState. Each CSI-SemiPersistentOnPUSCH-TriggerState contains only one CSI-ReportConfig associated with it. Each CSI-SemiPersistentOnPUSCH-TriggerStateList consists of up to 64 CSI-SemiPersistentOnPUSCH-TriggerStates (maxNrOfSemiPersistentPUSCH-Triggers is 64), and each CSI-SemiPersistentOnPUSCH-TriggerState contains only one associatedReportConfigInfo, corresponding to one CSI-ReportConfigId, which is associated with the corresponding CSI-ReportConfig through the CSI-ReportConfigId.

[0094] 9. CSI-RS number and nrofports count limit

[0095] In any slot, the UE is not expected to have more active CSI-RS ports or active CSI-RS resources in active BWPs than reported as capability.

[0096] For a certain moment, the number of CSI-RS resources associated with all CSI reports at that moment and the number of their corresponding ports cannot exceed the UE capabilities: maxNumberSimultaneousNZP-CSI-RS-PerCC, totalNumberPortsSimultaneousNZP-CSI-RS-PerCC.

[0097] If one or more CSI Report Setting refers to the CSI-RS resource N times, the resource and its corresponding port number are also counted N times. [NCJT]: For a CSI-RS Resource Set for channel measurement configured with two Resource Groups and N Resource Pairs,if a CSI-RS resource is referred X times by one of the M CSI-RS resources,where M is defined in clause 5.2.1.4.2,and / or one or two Resource Pairs,the CSI-RS resource and the CSI-RS ports within the CSI-RS resource are counted N times. X times.]).

[0098] The following, in conjunction with the accompanying drawings, describes in detail the information reporting method, apparatus, terminal and network-side equipment provided in the embodiments of the present application through some embodiments and their application scenarios.

[0099] See also Figure 6 , Figure 6 is a flow chart of an information reporting method provided by an embodiment of the present application, such as Figure 6 As shown, the information reporting method includes the following steps:

[0100] Step 101: The terminal receives target information sent by a network side device, wherein the target information is used to indicate whether to activate a target CSI reporting subconfiguration associated with a target channel state information CSI reporting configuration;

[0101] Step 102: When the target information indicates activation of a target CSI reporting subconfiguration associated with the target CSI reporting configuration, the terminal sends CSI to a network-side device based on the target CSI reporting subconfiguration.

[0102] The target CSI reporting configuration may be one or more CSI reporting configurations.

[0103] The target CSI reporting sub-configuration may be one or more CSI reporting sub-configurations.

[0104] The target information may be a media access control MAC control element CE or downlink control information (Downlink Control Information, DCI).

[0105] The target CSI reporting configuration (CSI report config) may be associated with one or more CSI reporting sub-configurations. The CSI reporting sub-configurations associated with the CSI reporting configuration may also be described as CSI reporting sub-configurations in the CSI reporting configuration.

[0106] In addition, the CSI reporting sub-configuration (sub-config CSI report) can also be described as sub-configuration CSI reporting, or simply referred to as sub-configuration (sub-config).

[0107] In the related art, the base station is not able to activate multiple CSI reporting sub-configurations through a single layer 1 or layer 2 signaling, where each CSI reporting sub-configuration corresponds to a spatial adjustment pattern. The signaling of the related art can only activate a single CSI report at a time, and lacks the function of activating the sub-configuration CSI report.

[0108] The target information in this embodiment may be MAC CE or DCI, and may support layer 1 (L1) / layer 2 (L2) signaling to trigger sub-configuration CSI reporting, and may support L1 / L2 signaling to trigger multiple sub-configuration CSI reporting at one time. The embodiment of the present application may use L1 / L2 signaling to trigger multiple sub-configuration CSI reporting in the same CSI reporting sub-configuration.

[0109] In an embodiment of the present application, a terminal receives target information sent by a network side device, wherein the target information is used to indicate whether to activate a target CSI reporting sub-configuration associated with a target channel state information CSI reporting configuration; when the target information indicates to activate a target CSI reporting sub-configuration associated with the target CSI reporting configuration, the terminal sends CSI to the network side device based on the target CSI reporting sub-configuration. In this way, the terminal can be supported to determine which sub-configuration CSI needs to be reported based on the activated CSI reporting sub-configuration, and the flexibility of the network side instructing the terminal to report CSI can be improved.

[0110] Optionally, in the case where the target information is a MAC CE, the target information indicates at least one of the following: whether to activate a semi-static target CSI reporting configuration; whether to activate a semi-static target CSI reporting sub-configuration;

[0111] or

[0112] In the case where the target information is DCI, the target information indicates at least one of the following: whether to activate a semi-static target CSI reporting configuration; whether to activate a semi-static target CSI reporting sub-configuration;

[0113] or

[0114] In the case where the target information is DCI, the target information indicates at least one of the following: whether to activate a non-periodic target CSI reporting configuration; whether to activate a non-periodic target CSI reporting sub-configuration.

[0115] In this embodiment, the UE reports one or more sub-configuration CSI reports belonging to the same CSI reporting configuration. The MAC CE activates one or more semi-static sub-configuration CSI reports belonging to the same CSI reporting configuration.

[0116] It should be noted that the MAC CE for triggering CSI reporting (report) in the related art cannot trigger one or more semi-static sub-config CSI reports in one or more semi-static CSI report configs. The MAC CE in this embodiment can realize the function of triggering sub-configuration CSI reporting.

[0117] In this embodiment, it is possible to support the network side device to activate the semi-static target CSI reporting configuration of the terminal or activate the semi-static target CSI reporting sub-configuration through MAC CE; or it is possible to support the network side device to activate the semi-static target CSI reporting configuration of the terminal or activate the semi-static target CSI reporting sub-configuration through DCI; or it is possible to support the network side device to activate the non-periodic target CSI reporting configuration of the terminal or activate the non-periodic target CSI reporting sub-configuration through DCI. This embodiment supports the function of indicating whether the sub-configuration CSI is sent through a single layer 1 / layer 2 signaling.

[0118] Optionally, the target information is a first MAC CE,

[0119] The first MAC CE includes status indication information of multiple CSI reporting configurations and status indication information of multiple CSI reporting sub-configurations associated with each CSI reporting configuration in the multiple CSI reporting configurations, and the multiple CSI reporting configurations include the target CSI reporting configuration.

[0120] In one implementation, the status indication information indicates an activation status, for example, activated or inactivated.

[0121] In one implementation manner, the target information is a first MAC CE, the first MAC CE includes a first part, a second part, and a third part, and the first part, the second part, and the third part are arranged in order from top to bottom;

[0122] The first part includes at least serving cell indication information and part of bandwidth BWP indication information;

[0123] The second part includes status indication information of multiple CSI reporting configurations, and in the second part, the status indication information of the multiple CSI reporting configurations is arranged from right to left in the order of the identifiers of the multiple CSI reporting configurations from small to large;

[0124] The third part includes status indication information of multiple CSI reporting sub-configurations associated with each CSI reporting configuration in the multiple CSI reporting configurations. In the third part, the CSI reporting sub-configurations associated with the multiple CSI reporting configurations are arranged from right to left in an ascending order of the identifiers of the multiple CSI reporting configurations, wherein the multiple CSI reporting sub-configurations associated with each of the CSI reporting configurations are arranged from right to left in an ascending order of the identifiers of the CSI reporting sub-configurations.

[0125] As a specific embodiment, the first MAC CE is a new MAC CE, which has both the function of activating the CSI reporting configuration and the function of activating the sub-configuration CSI reporting. At this time, the legacy MAC CE may no longer be used. The format of the first MAC CE is as follows: Figure 7a As shown, R represents a reserved bit, Si represents the status of the semi-static CSI reporting configuration in ReportConfigToAddModList, s0 refers to the CSI reporting configuration with the smallest CSI reporting configuration identifier (CSI-ReportConfigId) among all the semi-static CSI reporting configurations in ReportConfigToAddModList whose reporting types are configured as semiPersistentOnPUCCH, s1 refers to the CSI reporting configuration with the second smallest CSI-ReportConfigId, and so on; the bit value of Si is 1, which means that the semi-static CSI reporting configuration is activated, and the bit value of Si is 0, which means that it is deactivated.

[0126] In addition, if Figure 7a As shown, B represents the status of the L sub-configurations contained in the radio resource control (RRC) configuration in the semi-static CSI-ReportConfig in ReportConfigToAddModList, and Bij refers to the sub-configuration belonging to the Si reporting configuration; the number of bits occupied by Bij is related to the number of sub-configurations configured / activated by Si; for example, B00 refers to the activation status of the sub-configuration with the smallest CSI reporting sub-configuration identifier (sub-configId) in the CSI-ReportConfig with the smallest CSI-ReportConfigId among all semi-static CSI reporting configurations, and the activation status may include activation or inactivation; B01 refers to the activation status (activation / deactivation) of the sub-configuration with the second smallest sub-configId in the CSI-ReportConfig with the smallest CSI-ReportConfigId among all semi-static CSI reporting configurations; B10 refers to the activation status (activation / inactivation) of the sub-configuration with the smallest sub-configId among the second smallest CSI-ReportConfigId among all semi-static CSI reporting configurations.

[0127] exist Figure 7a In the example, S0 contains two sub-configurations {B00 and B01}, S1 contains four sub-configurations {B10, B11, B12, B13}, S2 contains four sub-configurations {B20, B21, B22, B23}, and S3 contains four sub-configurations {B30, B31, B32, B33}.

[0128] In this implementation mode, the target information is the first MAC CE, and the first MAC CE includes status indication information of multiple CSI reporting configurations and status indication information of multiple CSI reporting sub-configurations associated with each CSI reporting configuration in the multiple CSI reporting configurations, thereby supporting the simultaneous activation of multiple CSI reporting configurations through the first MAC CE, and activating one or more CSI reporting sub-configurations associated with the same CSI reporting configuration, thereby realizing L1 / L2signaling triggering CSI reporting of multiple CSI reporting configurations and CSI reporting sub-configurations at one time.

[0129] Optionally, the target information is a second MAC CE.

[0130] The second MAC CE includes status indication information of multiple CSI reporting sub-configurations associated with each CSI reporting configuration in multiple CSI reporting configurations, and the multiple CSI reporting configurations include the target CSI reporting configuration.

[0131] In one implementation manner, the target information is a second MAC CE, the second MAC CE includes a first part and a second part, and the first part and the second part are arranged in order from top to bottom;

[0132] The first part includes at least serving cell indication information and BWP indication information;

[0133] The second part includes status indication information of multiple CSI reporting sub-configurations associated with each CSI reporting configuration in multiple CSI reporting configurations. In the second part, the CSI reporting sub-configurations associated with the multiple CSI reporting configurations are arranged from right to left in an ascending order of the identifiers of the multiple CSI reporting configurations, wherein the multiple CSI reporting sub-configurations associated with each of the CSI reporting configurations are arranged from right to left in an ascending order of the identifiers of the CSI reporting sub-configurations.

[0134] In one implementation manner, the number of bits occupied by the status indication information of the multiple CSI reporting sub-configurations associated with each of the CSI reporting configurations is determined based on the number of CSI reporting sub-configurations configured or activated by each of the CSI reporting configurations.

[0135] As a specific embodiment, the second MAC CE is a new MAC CE, and the second MAC CE only has the function of activating the sub-configuration CSI reporting, and the legacy MAC CE activating the CSI report config can still be used.

[0136] like Figure 7bAs shown, B represents the status of the L sub-configurations contained in the RRC configuration of the semi-static CSI-ReportConfig in ReportConfigToAddModList, and Bij refers to the sub-configuration belonging to the Si reporting configuration; the number of bits occupied by Bij is related to the number of sub-configurations configured / activated by Si; for example, B00 refers to the activation status (activated / inactivated) of the sub-configuration with the smallest sub-configId in the CSI-ReportConfig with the smallest CSI-ReportConfigId among all semi-static CSI reporting configurations; B01 refers to the activation status (activated / deactivated) of the sub-configuration with the second smallest sub-configId in the CSI-ReportConfig with the smallest CSI-ReportConfigId among all semi-static CSI reporting configurations; B10 refers to the activation status (activated / inactivated) of the sub-configuration with the smallest sub-configId in the second smallest CSI-ReportConfigId among all semi-static CSI reporting configurations.

[0137] In this implementation, the target information is the second MAC CE, and the second MAC CE includes status indication information of multiple CSI reporting sub-configurations associated with each CSI reporting configuration in multiple CSI reporting configurations, so as to support the simultaneous activation of one or more CSI reporting sub-configurations associated with the same CSI reporting configuration through the second MAC CE, thereby realizing L1 / L2 signaling triggering CSI reporting of multiple CSI reporting sub-configurations at one time.

[0138] Optionally, the target information is a third MAC CE, and the third MAC CE includes status indication information of CSI reporting sub-configurations associated with all activated CSI reporting configurations on the BWP applied by the third MAC CE.

[0139] In one implementation, the target information is a third MAC CE, the third MAC CE includes a first part and a second part, and the first part and the second part are arranged in order from top to bottom;

[0140] The first part includes at least serving cell indication information and BWP indication information;

[0141] The second part includes status indication information of CSI reporting sub-configurations associated with all activated CSI reporting configurations on the BWP applied by the third MAC CE, and is arranged from right to left in ascending order of the identifiers of the CSI reporting sub-configurations.

[0142] As a specific embodiment, the third MAC CE is a new MAC CE, and the MAC CE only has the function of activating the sub-configuration CSI reporting, and the legacy MAC CE can still be used.

[0143] like Figure 7c As shown, the third MAC CE only supports activation of sub-configuration CSI reporting, Sub0 represents the activation status (activation / deactivation) of the sub-configuration with the smallest sub-configuration ID among all activated CSI report configs of the BWP ID, Sub1 represents the activation status (activation / deactivation) of the sub-configuration with the second smallest sub-configuration ID among all activated CSI report configs of the BWP ID, and so on, which will not be repeated here.

[0144] In this implementation mode, the target information is the third MAC CE, and the third MAC CE includes status indication information of the CSI reporting sub-configuration associated with all activated CSI reporting configurations on the BWP applied by the third MACCE, thereby supporting the simultaneous activation of one or more CSI reporting sub-configurations associated with the same CSI reporting configuration through the third MAC CE, thereby realizing L1 / L2 signaling triggering CSI reporting of multiple CSI reporting sub-configurations at one time.

[0145] Optionally, the DCI is used to activate a trigger state triggerState, and the triggerState is configured by RRC.

[0146] Optionally, in the case where the triggerState is used for non-periodic CSI reporting, the triggerState includes multiple CSI associated reporting configuration information CSI-AssociatedReportConfigInfo, each of the CSI-AssociatedReportConfigInfo includes: a target CSI reporting configuration identifier to be activated, a CSI-RS resource to be measured, and sub-configuration state information;

[0147] or

[0148] In the case where the triggerState is used for semi-static CSI reporting, the triggerState includes a CSI-AssociatedReportConfigInfo, and the CSI-AssociatedReportConfigInfo includes: a target CSI reporting configuration identifier to be activated, a CSI-RS resource to be measured, and sub-configuration state information;

[0149] The sub-configuration status information includes: a list of identifiers of CSI reporting sub-configurations to be activated or a bitmap of activation status of all CSI reporting sub-configurations associated with the target CSI reporting configuration.

[0150] In this embodiment, triggerState is activated by a DCI codepoint, thereby activating one or more non-periodic sub-configuration CSI reports in multiple non-periodic CSI reporting configurations; triggerState is activated by a DCI codepoint, thereby activating one or more semi-static sub-configuration CSI reports in multiple semi-static CSI reporting configurations.

[0151] In one implementation, the aperiodic triggerState is designed as follows: each CSI-AperiodicTriggerState includes multiple CSI-AssociatedReportConfigInfo;

[0152] Each CSI-AssociatedReportConfigInfo contains:

[0153] {

[0154] Report configuration identifier (reportConfigId);

[0155] resourcesForChannel, where each resourcesForChannel contains 1 nzp-CSI-RS or 1 csi-SSB-ResourceSet;

[0156] A bitmap of the sub-configuration activation status or a list of Ids of the sub-configurations to be activated (CSI-ReportSubConfigIdList (or bitmap)).

[0157] }

[0158] by Figure 8For example, each CSI-AperiodicTriggerState may contain multiple CSI-AssociatedReportConfigInfo. For the convenience of description, this embodiment only contains one AssociatedReportConfigInfo: each AssociatedReportConfigInfo contains CSI-ReportSubConfigIdList or bitmap. CSI-ReportSubConfigIdList refers to a list of a group of sub-configuration IDs to be activated, or CSI-ReportSubConfigId (or bitmap) represents the activation status (activated / inactivated) of each sub-configuration in the form of a bitmap. The bit length of each CSI-ReportSubConfigId is the number of sub-configurations L contained in the CSI-ReportConfig to which it belongs. The highest bit of the bitmap represents the activation status (activated / inactivated) of the sub-configuration with the smallest or largest sub-configuration ID, and the remaining bits correspond one-to-one in the order of sub-configuration IDs from small to large or from large to small.

[0159] In one implementation, the semi-static triggerState is designed as follows: the semi-static CSI-SemiPersistentOnPUSCH-TriggerState contains only one associatedReportConfigInfo, each associatedReportConfigInfo corresponds to a CSI-ReportConfigId and CSI-ReportSubConfigIdList (or bitmap), which is similar to the above-mentioned non-periodic triggerstate.

[0160] It should be noted that the current protocol framework does not support L1 signaling triggering multiple spatial domain (SD) / power domain (PD) adjustment patterns (adaptation pattern) of non-periodic sub-config CSI reports. This embodiment can achieve one DCI triggering multiple sub-config CSI reports by designing a new DCI trigger state.

[0161] Optionally, the target CSI reporting sub-configuration includes at least one of the following:

[0162] The identifier of the target CSI reporting sub-configuration;

[0163] First airspace information;

[0164] Second airspace information;

[0165] Power domain information;

[0166] The first spatial domain information includes: port subset indication; rank restriction; codebook subset restriction;

[0167] The second spatial domain information includes at least one non-zero power CSI reference signal CSI-RS resource.

[0168] In one implementation, the target CSI reporting sub-configuration includes the following parameters:

[0169] The ID of the target CSI reporting subconfiguration, such as CSI-ReportSubConfigId;

[0170] Airspace related information (including first airspace information and second airspace information);

[0171] Information about power domains.

[0172] The airspace related information includes:

[0173] Port subset indication can be used to distinguish the shutdown patterns of different ports in the case of Type I shutdown;

[0174] Rank restriction, which can be used for Type I shutdown. Different shutdown patterns can have different rank restrictions.

[0175] CodebookSubsetRestriction, which can be used for Type I shutdown. Different shutdown patterns can have different codebook subset restrictions.

[0176] One or a group of non-zero power CSI-RS resources can be used for Type II shutdown, with different resources representing different antenna port shutdown patterns.

[0177] Among them, one or a group of non-zero power CSI-RS resources can be in the form of a list of non-zero power CSI-RS resource IDs NZP-CSI-RS-ResourceList, or a group identifier of a CSI-RS resource group; or in the form of an Index of a NZP-CSI-RS resource contained in a group of main configurations, such as the CSIreport config (named as the main configuration) associated with the sub-configuration is configured with multiple NZP-CSI-RS resources associated, which are numbered according to the size of the ID. The number can be used as an index (Index), and each sub-configuration can be associated with some of the NZP-CSI-RS resources therein in the form of a group of Indexes. NZP-CSI-RS refers to non-zero power CSI-RS (Non-Zero Power CSI-RS).

[0178] It should be noted that the purpose of UE reporting CSI of multiple SD / PD adaptation patterns is to assist the base station in making TxRU shutdown decisions. When the UE reports CSI of multiple shutdown patterns, the base station can know under which shutdown patterns the CSI is better, and the network side may be more inclined to this shutdown pattern when making decisions.

[0179] Optionally, when the target CSI reporting subconfiguration includes the first spatial domain information but does not include the second spatial domain information, the terminal sends the CSI to the network side device based on the target CSI reporting subconfiguration, including: the terminal determines, based on the first spatial domain information, parameters required to calculate the CSI corresponding to the target CSI reporting subconfiguration, and sends the CSI corresponding to the target CSI reporting subconfiguration to the network side device; or

[0180] In a case where the target CSI reporting subconfiguration includes the second spatial domain information but does not include the first spatial domain information, the terminal sends CSI to a network side device based on the target CSI reporting subconfiguration, including: the terminal determines, based on the second spatial domain information, a CSI-RS measurement resource associated with the target CSI reporting subconfiguration, and sends CSI corresponding to the target CSI reporting subconfiguration to the network side device; or

[0181] In a case where the target CSI reporting subconfiguration includes the first spatial domain information and the second spatial domain information, the terminal sends CSI to a network side device based on the target CSI reporting subconfiguration, including: the terminal determines, based on the second spatial domain information, a CSI-RS measurement resource associated with the target CSI reporting subconfiguration, and sends CSI corresponding to the target CSI reporting subconfiguration to the network side device; or

[0182] In a case where the target CSI reporting subconfiguration includes the power domain information, the terminal sends CSI to a network side device based on the target CSI reporting subconfiguration, including: the terminal determines the parameters required to calculate the CSI corresponding to the target CSI reporting subconfiguration based on the power domain information, and sends the CSI corresponding to the target CSI reporting subconfiguration to the network side device.

[0183] Among them, the parameters required for calculating the CSI corresponding to the target CSI reporting subconfiguration may include: a port subset, a rank restriction, a codebook subset restriction, and at least one of one or a group of non-zero power CSI-RS resources. Taking non-zero power CSI-RS resources as an example, the parameters required for calculating the CSI corresponding to the target CSI reporting subconfiguration may include: a power control offset value of the non-zero power CSI-RS resource.

[0184] In one implementation, parameter configuration of a CSI reporting sub-configuration (such as a target CSI reporting sub-configuration) meets the following requirements: parameters of a Type I shutdown and a Type II shutdown, either of which is configured.

[0185] For example, if the CSI reporting sub-configuration includes the parameters of Type I shutdown, the UE calculates the CSI of the CSI reporting sub-configuration according to the parameters of Type I shutdown in the CSI reporting sub-configuration overwriting the corresponding parameters in the main configuration. The main configuration refers to the CSI reporting configuration associated with the CSI reporting sub-configuration. For example, if the rank restriction and codebook subset restriction are configured in the main configuration, but the rank restriction and codebook subset restriction are also included in the sub-configuration, when calculating the sub-configuration CSI, the UE refers to the rank restriction and codebook subset restriction contained in the sub-configuration.

[0186] For example, if the CSI reporting sub-configuration includes parameters of Type II shutdown, the UE calculates the CSI of the CSI reporting sub-configuration according to one or a group of NZP-CSI-RS resources included in the CSI reporting sub-configuration.

[0187] In one implementation, if the CSI reporting sub-configuration includes both Type I shutdown parameters and Type II shutdown parameters, the UE calculates the CSI of the CSI reporting sub-configuration according to one or a group of NZP-CSI-RSresource resources included in the CSI reporting sub-configuration; that is, the CSI of the CSI reporting sub-configuration is calculated according to the parameters of Type II shutdown;

[0188] In an implementation manner, if the CSI reporting sub-configuration includes parameters of a PD, the UE calculates the CSI of the CSI reporting sub-configuration by overwriting corresponding parameters in the main configuration with the parameters of the PD.

[0189] This embodiment can solve the problem of spatial domain (SD) / power domain (PD) joint configuration in the CSI reporting sub-configuration. Through this embodiment, the terminal can determine which parameters to refer to for calculating the CSI when the CSI reporting sub-configuration contains multiple parameters, for example, how to perform CSI reporting of the CSI reporting sub-configuration when it includes both spatial domain (SD) adjustment (Type I shutdown + Type II shutdown) and power domain (PD) adaptation parameters.

[0190] Optionally, the target CSI reporting subconfiguration includes the power domain information, and the power domain information includes: a target power control offset value or a first target power control offset value list, and the first target power control offset value list includes multiple target power control offset values;

[0191] The terminal sends CSI to a network side device based on the target CSI reporting sub-configuration, including:

[0192] If the target CSI reporting subconfiguration does not include the second spatial domain information, the terminal determines, based on the power domain information, the power control offset value of all non-zero power CSI-RS resources included in the CSI-RS resource set for channel measurement associated with the target CSI reporting subconfiguration; the terminal determines the CSI corresponding to the target CSI reporting subconfiguration based on the power control offset value; or

[0193] If the target CSI reporting subconfiguration includes the second spatial domain information, the terminal determines a power control offset value of a non-zero power CSI-RS resource included in the target CSI reporting subconfiguration based on the power domain information; the terminal determines the CSI corresponding to the target CSI reporting subconfiguration based on the power control offset value;

[0194] The terminal sends the CSI corresponding to the target CSI reporting sub-configuration to the network side device.

[0195] Among them, the power domain related information may include a target power control offset value (powerControlOffset), and the power control offset value may also be described as a power offset value. The powerControlOffset value in the power domain related information may be a single value. If the CSI reporting subconfiguration (such as the target CSI reporting subconfiguration) does not include parameters for Type II shutdown, that is, the CSI reporting subconfiguration does not include a set of NZP-CSI-RS resources, then the powerControlOffset value is applied to all NZP-CSI-RS resources contained in the CSI-RS resource set for channel measurement associated with the main configuration CSI report config associated with the CSI reporting subconfiguration; if the CSI reporting subconfiguration includes parameters for Type II shutdown, that is, the CSI reporting subconfiguration includes one or a group of NZP-CSI-RSresources, then the powerControlOffset value is applied to all NZP-CSI-RSresources contained in the CSI reporting subconfiguration.

[0196] For example, the CSI reporting sub-configuration includes second spatial domain information, the target power control offset value is a, and the CSI reporting sub-configuration contains 3 non-zero power CSI-RS resources. When calculating the CSI of the CSI reporting sub-configuration, the CSI of the CSI reporting sub-configuration is calculated based on the fact that the powerControlOffset values ​​of the 3 non-zero power CSI-RS ResourceIds are all a.

[0197] For example, the CSI reporting sub-configuration does not include the second spatial domain information, the target power control offset value is a, and all non-zero power CSI-RS resources included in the CSI-RS resource set for channel measurement in the main configuration associated with the CSI reporting sub-configuration include 3 non-zero power CSI-RS resources. When calculating the CSI of the CSI reporting sub-configuration, the CSI of the CSI reporting sub-configuration is calculated based on the fact that the values ​​of powerControlOffset of these 3 non-zero power CSI-RS ResourceIds are all a.

[0198] The power domain related information may include a first target power control offset value list, the first target power control offset value list is a PD parameter (parameter), the first target power control offset value list refers to a set of powerControlOffset values, and the number of elements in the first target power control offset value list is related to the following:

[0199] If the CSI reporting sub-configuration does not include parameters for Type II shutdown, that is, the CSI reporting sub-configuration does not include one or a group of NZP-CSI-RS resources, the number of elements in the first target power control offset value list is related to the number of NZP-CSI-RS resources included in the CSI-RS resource set (resource set) for channel measurement associated with the main configuration CSI report config associated with the CSI reporting sub-configuration. In one implementation, the element values ​​in the first target power control offset value list correspond one-to-one with the NZP-CSI-RS resources included in the CSI-RS resource set for channel measurement associated with the main configuration CSI report config according to the resource identifier (resourceId) from small to large or from large to small.

[0200] If the CSI reporting sub-configuration includes parameters for Type II shutdown, that is, the CSI reporting sub-configuration includes one or a group of NZP-CSI-RS resources, the number of elements in the first target power control offset value list is related to the number of the group of NZP-CSI-RS resources. In one implementation, the element values ​​in the first target power control offset value list correspond one-to-one with a group of NZP-CSI-RS resources included in the CSI reporting sub-configuration according to resourceId from small to large or from large to small.

[0201] In this implementation, when the power domain information includes a target power control offset value or a first target power control offset value list, the terminal can determine the power control offset value of all non-zero power CSI-RS resources included in the CSI-RS resource set for channel measurement associated with the target CSI reporting sub-configuration or the power control offset value of the non-zero power CSI-RS resources included in the target CSI reporting sub-configuration based on the target power control offset value or the first target power control offset value list, and perform channel measurement to obtain CSI based on the determined power control offset value, and perform CSI reporting of the target CSI reporting sub-configuration.

[0202] Optionally, when the power domain information includes the first target power control offset value list:

[0203] If the target CSI reporting subconfiguration does not include the second spatial domain information, the number of target power control offset values ​​in the first target power control offset value list corresponds to the number of all non-zero power CSI-RS resources included in the CSI-RS resource set for channel measurement in the target CSI reporting configuration associated with the target CSI reporting subconfiguration;

[0204] or

[0205] If the target CSI reporting subconfiguration includes the second spatial domain information, the number of target power control offset values ​​in the first target power control offset value list corresponds to the number of all non-zero power CSI-RS resources included in the target CSI reporting subconfiguration.

[0206] In one implementation, if the target CSI reporting sub-configuration does not include the second spatial domain information, the number of target power control offset values ​​in the first target power control offset value list is the same as the number of all non-zero power CSI-RS resources included in the CSI-RS resource set used for channel measurement in the target CSI reporting configuration associated with the target CSI reporting sub-configuration.

[0207] In one implementation, if the target CSI reporting subconfiguration includes the second spatial domain information, the number of target power control offset values ​​in the first target power control offset value list is the same as the number of all non-zero power CSI-RS resources included in the target CSI reporting subconfiguration.

[0208] Optionally, the multiple target power control offset values ​​in the first target power control offset value list correspond one-to-one with all non-zero power CSI-RS resources included in the CSI-RS resource set for channel measurement in the target CSI reporting configuration associated with the target CSI reporting subconfiguration according to the CSI-RS resource identifier from small to large or from large to small;

[0209] or

[0210] The multiple target power control offset values ​​in the first target power control offset value list correspond one-to-one with all non-zero power CSI-RS resources included in the target CSI reporting sub-configuration according to CSI-RS resource identifiers from small to large or from large to small.

[0211] Taking the one-to-one correspondence of CSI-RS resource identifiers (ResourceId) from small to large as an example, the CSI reporting sub-configuration includes the second spatial domain information, the first target power control offset value list is {a, b, c}, and the CSI reporting sub-configuration includes 3 non-zero power CSI-RS resources. When calculating the CSI reporting sub-configuration CSI, the CSI reporting sub-configuration CSI is calculated according to the powerControlOffset values ​​of these 3 non-zero power CSI-RSResourceIds from small to large, which are {a, b, c} respectively.

[0212] Taking the one-to-one correspondence of CSI-RS resource identifiers (ResourceId) from small to large as an example, the CSI reporting sub-configuration does not include the second spatial domain information, the first target power control offset value list is {a, b, c}, and all non-zero power CSI-RS resources included in the CSI-RS resource set for channel measurement in the main configuration associated with the CSI reporting sub-configuration include 3 non-zero power CSI-RS resources. When calculating the CSI of the CSI reporting sub-configuration, the powerControlOffset values ​​of these 3 non-zero power CSI-RSResourceIds from small to large are {a, b, c} respectively to calculate the CSI of the CSI reporting sub-configuration.

[0213] Optionally, the target CSI reporting subconfiguration includes the power domain information, and the power domain information includes a power control offset value index or a power control offset value index list;

[0214] The terminal sends CSI to a network side device based on the target CSI reporting sub-configuration, including:

[0215] The terminal determines, based on the power control offset value index or the power control offset value index list, a power control offset value from candidate power control offset values ​​of the non-zero power CSI-RS resource associated with the target CSI reporting subconfiguration;

[0216] The terminal determines, based on the power control offset value, the CSI corresponding to the target CSI reporting subconfiguration;

[0217] The terminal sends the CSI corresponding to the target CSI reporting sub-configuration to the network side device.

[0218] The power domain related information may include a power control offset value index (Index). The power control offset value Index may refer to a mapping between a set of candidate powerControlOffset values ​​configured for the CSI-RS resource associated with the CSI reporting sub-configuration (sub-config);

[0219] For example, if the CSI reporting sub-configuration does not contain a set of NZP-CSI-RS resources, and the main configuration CSI-RS resource associated with the CSI reporting sub-configuration is associated with 3 NZP-CSI-RS-Resources, where:

[0220] NZP-CSI-RS Resource 1 is configured with a set of powerControlOffset values: {a1 a2 a3 a4 a5a6};

[0221] NZP-CSI-RS Resource 2 is configured with a set of powerControlOffset values: {b1 b2 b3 b4 b5b6};

[0222] NZP-CSI-RS Resource 3 is configured with a set of powerControlOffset values: {c1 c2 c3 c4 c5c6};

[0223] If the power control offset value Index is 1, it means that when calculating the CSI corresponding to the sub-configuration, the first powerControlOffset value of the three NZP-CSI-RS-Resources takes effect, that is, the powerControlOffset value of resource1 is a1, the powerControlOffset value of resource2 is b1, and the powerControlOffset value of resource3 is c1.

[0224] For example, if the CSI reporting sub-configuration contains a set of NZP-CSI-RS resources, the number is 4, where:

[0225] NZP-CSI-RS Resource 1 is configured with a set of powerControlOffset values: {a1 a2 a3 a4 a5a6};

[0226] NZP-CSI-RS Resource 2 is configured with a set of powerControlOffset values: {b1 b2 b3 b4 b5b6};

[0227] NZP-CSI-RS Resource 3 is configured with a set of powerControlOffset values: {c1 c2 c3 c4 c5c6};

[0228] NZP-CSI-RS Resource 4 is configured with a set of powerControlOffset values: {d1 d2 d3 d4 d5d6};

[0229] If the power control offset value Index is 2, it means that when calculating the CSI corresponding to the sub-configuration, the second powerControlOffset value of the four NZP-CSI-RS-Resources referenced is effective, that is, the powerControlOffset value of resource1 is a2, the powerControlOffset value of resource2 is b2, the powerControlOffset value of resource3 is c2, and the powerControlOffset value of resource4 is d2.

[0230] The power domain related information may include a power control offset value Index list, where each element in the power control offset value Index list corresponds to the number of the powerControlOffset value of each CSI-RS Resource in all candidate powerControlOffsets in the resource associated with the CSI reporting subconfiguration according to the CSI-RSResource Id from small to large or from large to small;

[0231] For example, the main configuration CSI-RS resource associated with the CSI reporting sub-configuration is associated with three NZP-CSI-RS-Resources, where:

[0232] NZP-CSI-RS Resource 1 is configured with a set of powerControlOffset values: {a1 a2 a3 a4 a5a6};

[0233] NZP-CSI-RS Resource 2 is configured with a set of powerControlOffset values: {b1 b2 b3 b4 b5b6};

[0234] NZP-CSI-RS Resource 3 is configured with a set of powerControlOffset values: {c1 c2 c3 c4 c5c6};

[0235] If the power control offset value Index list is {1,2,1}, it means that when calculating the CSI corresponding to the CSI reporting sub-configuration, the first powerControlOffset value a1 of NZP-CSI-RS Resource1 is effective, the second powerControlOffset value b2 of NZP-CSI-RSResource2 is effective, and the first powerControlOffset value c1 of NZP-CSI-RS Resource3 is effective.

[0236] For example, if the CSI reporting sub-configuration contains a set of NZP-CSI-RS resources, the number is 4, where:

[0237] NZP-CSI-RS Resource 1 is configured with a set of powerControlOffset values: {a1 a2 a3 a4 a5a6};

[0238] NZP-CSI-RS Resource 2 is configured with a set of powerControlOffset values: {b1 b2 b3 b4 b5b6};

[0239] NZP-CSI-RS Resource 3 is configured with a set of powerControlOffset values: {c1 c2 c3 c4 c5c6};

[0240] NZP-CSI-RS Resource 4 is configured with a set of powerControlOffset values: {d1 d2 d3 d4 d5d6};

[0241] If the power control offset value Index list is {1,2,1,3}, it means that when calculating the CSI corresponding to the CSI reporting sub-configuration, the first powerControlOffset value a1 of NZP-CSI-RS Resource1 of the referenced 4 CSI-RSs is effective, the second powerControlOffset value b2 of NZP-CSI-RS Resource2 is effective, the first powerControlOffset value c1 of NZP-CSI-RSResource3 is effective, and the third powerControlOffset value d3 of NZP-CSI-RS Resource4 is effective.

[0242] In this implementation, when the power domain information includes a power control offset value index or a power control offset value index list, the terminal can determine the power control offset value from the candidate power control offset values ​​of the non-zero power CSI-RS resources associated with the target CSI reporting sub-configuration according to the power control offset value index or the power control offset value index list, perform channel measurement to obtain CSI according to the determined power control offset value, and perform CSI reporting of the target CSI reporting sub-configuration.

[0243] Optionally, there is a mapping relationship between the power control offset value index and a candidate power control offset value of each non-zero power CSI-RS resource in a plurality of non-zero power CSI-RS resources associated with the target CSI reporting subconfiguration;

[0244] or

[0245] There is a one-to-one mapping relationship between the multiple power control offset value indexes in the power control offset value index list and the candidate power control offset values ​​of the multiple non-zero power CSI-RS resources associated with the target CSI reporting sub-configuration.

[0246] Optionally, the target CSI reporting subconfiguration includes the power domain information, the power domain information includes a second target power control offset value list or a power control offset value offset, the second target power control offset value list is used to characterize the offset of the power control offset value of each non-zero power CSI-RS resource associated with the target CSI reporting subconfiguration, and the power control offset value offset is used to characterize the offset of the power control offset value of each non-zero power CSI-RS resource associated with the target CSI reporting subconfiguration;

[0247] The terminal sends CSI to a network side device based on the target CSI reporting sub-configuration, including:

[0248] The terminal determines, based on the second target power control offset value list, an offset of a power control offset value of each non-zero power CSI-RS resource associated with the target CSI reporting subconfiguration relative to a first original value, or the terminal determines, based on the power control offset value offset, an offset of a power control offset value of each non-zero power CSI-RS resource associated with the target CSI reporting subconfiguration relative to a second original value; wherein the first original value is a power control offset value of each non-zero power CSI-RS resource associated with the target CSI reporting configuration associated with the target CSI reporting subconfiguration, and the second original value is a power control offset value of each non-zero power CSI-RS resource associated with the target CSI reporting subconfiguration;

[0249] The terminal determines the CSI corresponding to the target CSI reporting subconfiguration based on the determined power control offset value;

[0250] The terminal sends the CSI corresponding to the target CSI reporting sub-configuration to the network side device.

[0251] The power control offset value offset may be an offset value relative to the powerControlOffset of the original CSI-RS Resource. The second target power control offset value list may be an offset value list relative to the powerControlOffset of the original CSI-RS Resource.

[0252] For example, the main configuration CSI-RS resource associated with the CSI reporting sub-configuration is associated with three NZP-CSI-RS-Resources, where:

[0253] The value of powerControlOffset of NZP-CSI-RS Resource 1 is a;

[0254] The powerControlOffset value of NZP-CSI-RS Resource 2 is b;

[0255] The powerControlOffset value of NZP-CSI-RS Resource 3 is c;

[0256] If the power control offset value is 2, when calculating the CSI corresponding to the CSI reporting sub-configuration, the powerControlOffset value of NZP-CSI-RS Resource1 is increased or decreased by 2dB relative to the original value a, the powerControlOffset value of NZP-CSI-RSResource2 is increased or decreased by 2dB relative to the original value b, and the powerControlOffset value of NZP-CSI-RSResource3 is increased or decreased by 2dB relative to the original value c.

[0257] For example, the CSI reporting sub-configuration contains four CSI-RS resources, including:

[0258] The value of powerControlOffset of NZP-CSI-RS Resource 1 is a;

[0259] The powerControlOffset value of NZP-CSI-RS Resource 2 is b;

[0260] The powerControlOffset value of NZP-CSI-RS Resource 3 is c;

[0261] The value of powerControlOffset of NZP-CSI-RS Resource 4 is d;

[0262] If the power control offset value is 2, when calculating the CSI corresponding to the CSI reporting sub-configuration, the powerControlOffset value of NZP-CSI-RS Resource1 is increased or decreased by 2dB relative to the original value a, the powerControlOffset value of NZP-CSI-RSResource2 is increased or decreased by 2dB relative to the original value b, the powerControlOffset value of NZP-CSI-RSResource3 is increased or decreased by 2dB relative to the original value c, and the powerControlOffset value of NZP-CSI-RSResource4 is increased or decreased by 2dB relative to the original value d.

[0263] For example, the main configuration CSI-RS resource associated with the CSI reporting sub-configuration is associated with three NZP-CSI-RS-Resources, where:

[0264] The value of powerControlOffset of NZP-CSI-RS Resource 1 is a;

[0265] The powerControlOffset value of NZP-CSI-RS Resource 2 is b;

[0266] The powerControlOffset value of NZP-CSI-RS Resource 3 is c;

[0267] If the second target power control offset value list is {1,2,1}, when calculating the CSI corresponding to the CSI reporting sub-configuration, the powerControlOffset value of NZP-CSI-RS Resource1 is increased or decreased by 1dB relative to the original value a, the powerControlOffset value of NZP-CSI-RS Resource2 is increased or decreased by 2dB relative to the original value b, and the powerControlOffset value of NZP-CSI-RS Resource3 is increased or decreased by 1dB relative to the original value c.

[0268] For example, the CSI reporting sub-configuration contains four CSI-RS resources, including:

[0269] The value of powerControlOffset of NZP-CSI-RS Resource 1 is a;

[0270] The powerControlOffset value of NZP-CSI-RS Resource 2 is b;

[0271] The powerControlOffset value of NZP-CSI-RS Resource 3 is c;

[0272] The value of powerControlOffset of NZP-CSI-RS Resource 4 is d;

[0273] If the second target power control offset value list is {1,2,1,3}, when calculating the CSI corresponding to the CSI reporting sub-configuration, the powerControlOffset value of NZP-CSI-RS Resource1 is increased or decreased by 1dB relative to the original value a, the powerControlOffset value of NZP-CSI-RS Resource2 is increased or decreased by 2dB relative to the original value b, the powerControlOffset value of NZP-CSI-RS Resource3 is increased or decreased by 1dB relative to the original value c, and the powerControlOffset value of NZP-CSI-RS Resource4 is increased or decreased by 3dB relative to the original value d.

[0274] In this implementation, when the power domain information includes a second target power control offset value list, the terminal can determine the offset of the power control offset value of each non-zero power CSI-RS resource associated with the target CSI reporting sub-configuration relative to the original value according to the second target power control offset value list, and perform channel measurement to obtain CSI according to the determined power control offset value, and perform CSI reporting of the target CSI reporting sub-configuration.

[0275] Optionally, the terminal sending CSI to a network side device based on the target CSI reporting subconfiguration includes:

[0276] When multiple power control offset values ​​are configured in the non-zero power CSI-RS resource for channel measurement associated with the target CSI reporting configuration and the target CSI reporting subconfiguration does not exist, the terminal determines the CSI corresponding to the target CSI reporting configuration based on the first power control offset value in the non-zero power CSI-RS resource;

[0277] The terminal sends the CSI corresponding to the target CSI reporting configuration to the network side device.

[0278] In one implementation, if multiple powerControlOffset values ​​are configured in the NZP-CSI-RS resource for channel measurement associated in the CSI report config, and the CSI report config is not reported by the activated sub-configuration, the UE calculates the CSI of the CSI report config according to the first powerControlOffset value of each resource.

[0279] In this implementation, when multiple power control offset values ​​are configured in the non-zero power CSI-RS resource for channel measurement associated with the target CSI reporting configuration, and the target CSI reporting sub-configuration does not exist, the terminal performs channel measurement to obtain CSI based on the first power control offset value in the non-zero power CSI-RS resource, and performs CSI reporting of the target CSI reporting sub-configuration.

[0280] Optionally, when a CSI-RS resource is associated with one or more CSI reporting configurations and CSI reporting sub-configurations, the number of CSI-RS ports Nrofports activated at the target time and the CSI-RS resource are counted as follows:

[0281] If the CSI-RS resource is referenced N times by the one or more CSI reporting configurations and CSI reporting subconfigurations, the CSI-RS resource and the number of CSI-RS ports corresponding to the CSI-RS resource are counted N times, where N is a positive integer.

[0282] In one implementation, if a CSI Report Config includes one or more CSI Report sub-configs, the number of CSI-RS ports Nrofports / simultaneous activate resource is counted as follows:

[0283] If a CSI-RS resource is referenced N times by one or more sub-configuration CSI reports, then the CSI-RS resource and the number of its corresponding CSI-RS ports shall be counted N times.

[0284] It should be noted that, since the CSI framework in the related art is changed to configure L sub-configs for a CSI report config and N of the sub-configurations are activated, the CSI-RS resource and nrofports counting method in the related art need to adapt to the change.

[0285] This embodiment can solve the problem of how to count NZP-CSI-RS resource and its nrofports when a CSI report config includes multiple sub-config CSIreports.

[0286] Optionally, the first number of symbols and the second number of symbols corresponding to the target CSI reporting configuration meet the delay requirement agreed upon in the protocol;

[0287] The first number of symbols is the number of symbols between a physical downlink control channel (PDCCH) for scheduling the target CSI reporting configuration and a CSI report;

[0288] The second number of symbols is the number of symbols between the target non-zero power CSI-RS resource and the CSI report, and the target non-zero power CSI-RS resource is the non-zero power CSI-RS resource with the earliest transmission time for channel measurement associated with the target CSI reporting configuration and the CSI reporting sub-configuration associated with the target CSI reporting configuration.

[0289] In one implementation, if a CSI Report Config includes one or more CSI Report sub-configs, then:

[0290] The number of symbols between the PDCCH scheduling CSI Report Config and the CSI report (report) is denoted as Z;

[0291] The number of symbols between the earliest NZP-CSI-RS resource for channel measurement associated with the main configuration CSI report and the sub-configuration CSI report in the CSI Report Config and the CSI report is recorded as Z';

[0292] The number of symbols Z and the number of symbols Z' meet the delay requirements of 5.4-1 and 5.4-2 in the existing 38.214 (protocol regulations), and the delay requirement is a specific number of symbols. The existing protocol stipulates a processing delay, that is, a period of time, and its purpose is to stipulate that the terminal device must complete the channel measurement process within this period of time. Correspondingly, the base station can instruct the terminal device where to report the CSI based on this period of time. Generally speaking, the location of reporting CSI should be after the channel measurement is completed. It can be seen that the processing delay for CSI is determined based on two parameters, namely Z and Z'. Its essential meaning is that Z is used to describe the analysis of DCI, and Z' is used to describe the measurement of the channel state.

[0293] In the protocol, detailed values ​​of Z and Z' are given, as shown in Table 1 and Table 2. Table 1 and Table 2 are cited from Protocol 38.214.

[0294] Table 1

[0295]

[0296] Table 2

[0297]

[0298] Among them, the subscripts 1, 2, and 3 of Z represent different requirements. Table 1 and Table 2 correspond to two CSI calculation delay requirements, respectively. Table 1 corresponds to requirement 1, and Table 2 corresponds to requirement 2. In Tables 1 and 2, μ represents the subcarrier spacing, Xμ corresponds to a capability beam reporting time beamReportTiming reported by the UE, KB1 is the capability beam switching time beamSwitchTiming reported by the UE, and l in KB1 can take the value of 1, 2, 3, or 4.

[0299] Comparing the data in Table 1 and Table 2, it can be seen that the specific values ​​of Z and Z' corresponding to Table 1 are much smaller than those in Table 2. That is to say, the processing delay corresponding to the data in Table 1 should be shorter. Therefore, it can be understood that the requirement corresponding to requirement 1 should be more complex.

[0300] The present application also provides a counting method, which includes:

[0301] When a CSI-RS resource is associated with one or more CSI reporting configurations and CSI reporting sub-configurations, the number of CSI-RS ports Nrofports activated at the target time and the CSI-RS resource are counted as follows:

[0302] If the CSI-RS resource is referenced N times by the one or more CSI reporting configurations and CSI reporting subconfigurations, the CSI-RS resource and the number of CSI-RS ports corresponding to the CSI-RS resource are counted N times, where N is a positive integer.

[0303] The target time may be a single time slot, that is, in one slot, the activated CSI-RS port or CSI-RS resource on the activated BWP cannot exceed the capability reported by the UE.

[0304] The information reporting method provided in the embodiment of the present application is described through several specific embodiments:

[0305] In the following embodiments, the CSI reporting sub-configuration is referred to as sub-configuration for short.

[0306] Embodiment 1:

[0307] In this embodiment, a sub-configuration framework is described.

[0308] In this embodiment, the CSI reporting configuration includes a group of sub-configuration IDs as follows:

[0309]

[0310] The CSI reporting configuration includes a group of sub-configuration IDs, such as subConfigurationIdList={1,2,4,6,7}, that is, the main configuration includes 5 sub-configurations, and the sub-configuration IDs are {1,2,4,6,7} respectively.

[0311] The following are examples of sub-configurations:

[0312] Example 1:

[0313]

[0314] The sub-configuration Id=1 corresponds to an SD+PD adaptation pattern, which includes parameters for sub-configuration CSI calculation in the case of SD (spatial domain) TypeI shutdown and PD (power domain) adaptation. The remaining required parameters refer to the main CSI Reportconfig to which the sub-configuration belongs.

[0315] Example 2:

[0316]

[0317] The sub-configuration Id=2 corresponds to an SD+PD adaptation pattern, which includes parameters and CSI-RS resources for sub-configuration CSI calculation in SD (spatial domain) Type II shutdown and PD (power domain) adaptation.

[0318] Example 3:

[0319]

[0320] The sub-configuration Id=4 corresponds to an SD adaptation pattern, which includes CSI-RS resources used for sub-configuration CSI calculation when SD (spatial domain) Type II is shut down.

[0321] Example 4:

[0322]

[0323] The sub-configuration Id=6 corresponds to an SD adaptation pattern, which includes parameters for sub-configuration CSI calculation when SD (spatial domain) Type I is shut down.

[0324] Example 5:

[0325]

[0326] The sub-configuration Id=7 corresponds to a PD adaptation pattern, which includes parameters for sub-configuration CSI calculation in the case of PD (power domain) adaptation.

[0327] Embodiment 2:

[0328] The CSI-ResourceConfigId corresponding to resourcesForChannelMeasurement in the main CSI report config contains four CSI-RS resources for channel measurement, NZP-CSI-RS ResourcesId = 1, 2, 3, 4, and the sub-configuration contains both a set of CSI-RS resource Id = 5, 6, 7 and PD adaptation parameters. The configuration methods of PD adaptation related parameters are as follows:

[0329] Method 1: Explicitly configure the powerControlOffset value in the sub-configuration. Since the sub-configuration contains three CSI-RS resources, three powerControlOffset values ​​need to be configured. Assuming the configuration is {a, b, c}, when calculating the CSI of the sub-configuration, the powerControlOffset values ​​of the three CSI-RS ResourceIds from small to large are {a, b, c} respectively to calculate the CSI of the sub-configuration.

[0330] Method 2: Explicitly configure the offset value of powerControlOffset in the sub-configuration. Since the sub-configuration contains 3 CSI-RS Resources, 3 offset values ​​of powerControlOffset need to be configured. Assuming that the original powerControlOffset value of CRI-RSResource Id = 5, 6, 7 is {a, b, c}, if the offset value of powerControlOffset in the sub-configuration is configured as {i, j, k}, then when calculating the CSI of the sub-configuration, the powerControlOffset values ​​of the 3 CSI-RSResourceIds from small to large are {a+i, b+j, c+k} or {ai, bj, ck} to calculate the CSI of the sub-configuration;

[0331] Mode 3: The sub-configuration contains three CSI-RS resources. The powerControlOffste configuration value of each CSI-RS Resource is as follows:

[0332] The candidates for the powerControlOffset value of NZP-CSI-RS Resource 1 are {a1,a2,a3,a4,a5};

[0333] The candidates for the powerControlOffset value of NZP-CSI-RS Resource 2 are {b1,b2,b3,b4,b5};

[0334] The candidates for the powerControlOffset value of NZP-CSI-RS Resource 3 are {c1,c2,c3,c4,c5};

[0335] If the powerControlOffsetList in the sub-configuration is configured as {1}, it can be understood that the first candidate value of all resources in the sub-configuration takes effect, that is, the powerControlOffset of NZP-CSI-RS Resource 1 is a1, the powerControlOffset of NZP-CSI-RS Resource 2 is b1, and the powerControlOffset of NZP-CSI-RS Resource 3 is c1;

[0336] That is, the element value X in powerControlOffsetList represents that the Xth powerControlOffset value of all CSI-RS Resources in the sub-configuration is effective.

[0337] If the powerControlOffsetList in the sub-configuration is configured as {2,3,1}, it can be understood that the powerControlOffset of NZP-CSI-RS Resource 1 is a2, the powerControlOffset of NZP-CSI-RS Resource 2 is b3, and the powerControlOffset of NZP-CSI-RS Resource 3 is c1;

[0338] That is, the first element value X in powerControlOffsetList represents that the Xth powerControlOffset of the NZP-CSI-RS Resource with the smallest resource ID in the sub-configuration is effective, the second element value Y represents that the Yth powerControlOffset of the NZP-CSI-RS Resource with the second smallest resource ID in the sub-configuration is effective, ..., and the meanings of the element values ​​in the remaining positions are similar.

[0339] Embodiment 3:

[0340] This embodiment describes the design of MAC CE for activating sub-configuration CSI reporting.

[0341] This embodiment provides a MAC CE for activating sub-configuration CSI reporting. The MAC CE can be used to activate sub-configuration CSI reporting.

[0342] In one implementation, the format of the MAC CE is as follows: Fig. 9 shown.

[0343] In the MAC CE, S0 / S1 / S2 / S3 respectively represent the activation status (activation / deactivation) of all CSI-ReportConfigs whose reporting type is semiPersistentOnPUCCH and CSI-ReportConfigId from small to large in ReportConfigToAddModList; in this embodiment, each main configuration can contain at most 8 sub-configurations;

[0344] B00-B07 (sub-configuration) represents the sub-configuration associated with S0 (main configuration), and represents the activation status (activated / inactivated) of the sub-configuration from the smallest to the largest sub-configuration ID;

[0345] B10-B17 (sub-configuration) represents the sub-configuration associated with S1 (main configuration), and represents the activation status (activated / inactivated) of the sub-configuration from the smallest sub-configuration ID to the largest sub-configuration ID.

[0346] B20-B27 (sub-configuration) represents the sub-configuration associated with S2 (main configuration), and represents the activation status (activated / inactivated) of the sub-configuration from the smallest sub-configuration ID to the largest sub-configuration ID.

[0347] B30-B37 (sub-configuration) represent the sub-configuration associated with S3 (main configuration), and represent the activation status (activated / inactivated) of the sub-configuration with sub-configuration ID from small to large.

[0348] In one implementation, the format of the MAC CE is as follows: Fig.10 shown.

[0349] In the MAC CE, S0 / S1 / S2 / S3 respectively represent the activation status (activation / deactivation) of all CSI-ReportConfigs whose reporting type is semiPersistentOnPUCCH and CSI-ReportConfigId from small to large in ReportConfigToAddModList; in this embodiment, each main configuration can contain at most 4 sub-configurations;

[0350] B00-B03 (sub-configuration) represents the sub-configuration associated with S0 (main configuration), and represents the activation status (activated / inactivated) of the sub-configuration from the smallest to the largest sub-configuration ID;

[0351] B10-B13 (sub-configuration) represent the sub-configuration associated with S1 (main configuration), and represent the activation status (activated / inactivated) of the sub-configuration with the sub-configuration ID from the smallest to the largest.

[0352] B20-B23 (sub-configuration) represent the sub-configuration associated with S2 (main configuration), and represent the activation status (activated / inactivated) of the sub-configuration from the smallest sub-configuration ID to the largest sub-configuration ID.

[0353] B30-B33 (sub-configuration) represent the sub-configuration associated with S3 (main configuration), and represent the activation status (activated / inactivated) of the sub-configuration with sub-configuration ID from small to large.

[0354] It should be noted that in Fig. 9 and Fig.10 In the two MAC CEs shown, the number of sub-configurations contained in each main configuration is fixed. In the first MAC CE, each main configuration contains 8 sub-configurations, and each row represents the activation status of the 8 sub-configurations; in the second MAC CE, each main configuration contains 4 sub-configurations, and the activation status (activation / deactivation) of each sub-configuration is arranged from right to left and from top to bottom according to the size of the main configuration ID and the size of the sub-configuration ID.

[0355] Embodiment 4:

[0356] The relationship between the main configuration CSI report config and the sub-configuration sub-config CSI report can be divided into the following cases (taking semi-static main configuration and sub-configuration as an example, the non-periodic main configuration and sub-configuration are similar and are not repeated here):

[0357] A CSI reporting configuration (i.e., CSI report config) does not contain any sub-configuration (i.e., sub-config CSIreport), which is the same as the existing traditional CSI framework. That is, if the CSI reporting configuration is activated or deactivated, it is still based on whether the MAC CE indicates that the CSI reporting configuration is activated;

[0358] A CSI reporting configuration contains multiple sub-configurations. The CSI reporting configuration is called the main configuration, and the multiple sub-configurations it contains correspond to multiple spatial adaptation patterns. In this case, the relationship between the main configuration and the sub-configurations can also be divided into the following categories:

[0359] As long as the CSI reporting configuration is activated, the CSI of the main configuration is reported by default; whether the sub-configuration CSI contained in it is activated depends on the indication of MAC CE;

[0360] After the CSI reporting configuration is activated, the main configuration can be understood as sub-config0 by default. Whether to activate the CSI reporting of the main configuration (sub-config0) depends on the instruction of the MAC CE.

[0361] Assume that a CSI reporting configuration includes three CSI reporting sub-configurations, and the MAC CE architecture indicating activation of the CSI reporting configuration and CSI reporting sub-configuration is as follows: Fig.11 As shown in the figure, each CSI reporting configuration is allowed to have up to 4 sub-configurations. By default, as long as the CSI reporting configuration is activated, the CSI of the main configuration will be reported. For example, the MAC CE actually sent is as follows Fig.12 As shown, the UE understands that the two CSI reportconfigs with the second smallest and fourth smallest reportConfigId in the CSI report config associated with the BWP are triggered. For the convenience of description, they are named CSI report configA and CSIreport configB, and the CSI of these two main configurations will be reported. The sub-configuration CSI with the second smallest sub-configuration ID in CSI report configA is activated, and the sub-configuration CSI with the smallest and second smallest sub-configuration ID in CSI report configB is also activated.

[0362] The embodiments of the present application are designed to trigger L1 / L2 signaling for CSI reporting of multiple sub-configurations in the same CSI reporting configuration; the embodiments of the present application provide a framework for CSI reporting sub-configuration when PD+SD is jointly configured; the embodiments of the present application provide UE's understanding of sub-configuration parameters when facing different CSI reporting sub-configuration combinations.

[0363] See also Fig.13 , Fig.13 is a flow chart of an information reporting method provided by an embodiment of the present application, such as Fig.13 As shown, the information reporting method includes the following steps:

[0364] Step 201: The network side device sends target information to the terminal, wherein the target information is used to indicate whether to activate the CSI reporting sub-configuration associated with the target CSI reporting configuration;

[0365] Step 202: When the target information indicates activation of a target CSI reporting sub-configuration associated with the target CSI reporting configuration, the network side device receives CSI sent by the terminal based on the target CSI reporting sub-configuration.
