Description

Technical Field

[0001] This document generally covers wireless communication, particularly fifth-generation (5G) wireless communication, and specifically addresses channel state information (CSI) measurement and reporting. Background Technology

[0002] With the development of wireless communication technology, the transmission rate, throughput, reliability, and other performance indicators of wireless communication systems have been greatly improved through the use of high-frequency bands, large bandwidths, multiple antennas, and other technologies. At the same time, with the deployment of 5G technology, greenhouse gas emissions caused by 5G base stations (e.g., gNBs) and their high power consumption have become a serious problem. Therefore, network energy conservation is not only important for green communication systems but also for reducing operating costs.

[0003] To reduce the power consumption of gNBs, one potential approach is to reduce the number of antennas or antenna ports. Variations in the number of antennas or antenna ports can impact CSI measurements or CSI reporting. Therefore, a new method is needed to correlate CSI measurements and / or CSI reporting for different numbers of antennas or antenna ports. Summary of the Invention

[0093] Figure 14 A flowchart of a method according to an embodiment of the present disclosure is shown. Detailed Implementation

[0094] Figure 1 A schematic diagram of a network (architecture) according to an embodiment of the present disclosure is shown. Figure 1 In this context, a network includes the following network functions / entities:

[0095] 1) UE: User Equipment

[0096] 2) RAN: Radio Access Network

[0097] In this disclosure, RAN can be equal to RAN node or Next Generation RAN (NG-RAN) (node).

[0098] 3) AMF: Access and Mobility Management Function

[0099] AMF includes the following functions: registration management, connection management, reachability management, and mobility management. AMF terminates RAN control plane (CP) interface N2 and NAS interface N1, and provides Non-Access Stratum (NAS) encryption and integrity protection. It also distributes Session Management (SM) NAS via interface N11 to the appropriate Session Management Function (SMF). AMF provides services to other Consumer Network Functions (NFs) to subscribe to or receive notifications of mobility-related events and information.

[0100] 4) SMF: Session Management Function

[0101] The SMF includes the following functions: session establishment, modification and release; UE IP address allocation and management (including optional authorization functions); selection and control of user plane (UP) functions; and downlink data notification. The SMF can subscribe to mobility-related events and information from the AMF.

[0102] 5) UPF: User Plane Function

[0103] UPF includes the following functions: acting as an anchor point for mobility within / between Radio Access Technologies (RATs) and an external session point for interconnection with data networks, packet routing and forwarding indicated by SMF, service usage reporting, Quality of Service (QoS) processing for UPs, downlink packet buffering, and downlink data notification triggering, etc.

[0104] 6) UDM: Unified Data Management

[0105] The UDM manages the UE's subscription profile. The subscription includes data for mobility management (e.g., restricted areas) and session management (e.g., QoS profile per DNN per slice). The subscription data also includes slice selection parameters used by the AMF to select the appropriate SMF. The AMF and SMF receive subscriptions from the UDM. The subscription data is stored in the Unified Data Repository (UDR). The UDM uses this data upon receiving a request from the AMF or SMF.

[0106] 7) PCF: Policy Control Function

[0107] The PCF supports a unified policy framework for managing network behavior. The PCF provides access management policies to the AMF, session management policies to the SMF, and / or UE policies to the UE. The PCF can access the UDR to obtain subscription information related to policy decisions. The PCF can also generate policies for managing network behavior based on subscriptions and instructions from application functions (AFs). The PCF can then provide policy rules for implementing CP functions (e.g., AMF and / or SMF).

[0108] 8) NEF: Network Exposure Function

[0109] NEF supports exposing network capabilities and events to AFs. Third-party AFs can invoke services provided by the network via NEF, and NEF performs authentication and authorization for third-party applications. NEF also provides translation of information exchanged with AFs and with internal NFs.

[0110] 9) AF: Application Functions

[0111] The Application Front-End (AF) interacts with the core network to provide services, such as supporting: the impact of applications on service routing, accessing the External Network Framework (NEF), and interacting with the policy framework used for policy control. An AF can be considered trusted by the operator and may be allowed to interact directly with the relevant Functional Level (NF). AFs that are not allowed to directly access NFs by the operator should interact with the relevant NFs via the NEF using the External Exposure Framework. AFs can store application information in the User Data Receipt (UDR) via the NEF.

[0112] In some embodiments, for CSI measurements, the UE should perform the measurement based on the CSI-RS (reference signal) and may report the corresponding report (e.g., measurement results) to the gNB.

[0113] In one embodiment, a UE can be configured with multiple CSI reporting configurations via CSI-ReportConfig signaling. CSI-ReportConfig is associated with one or more CSI-RS resource settings indicated by CSI-resourceConfigID. These CSI-RS resource settings are configured via CSI-ResourceConfig signaling.

[0114] In one embodiment, a CSI-RS resource setting may include multiple CSI-RS resource sets. The CSI-RS resource sets are configured by the NZP-CSI-RS-ResourceSet signaling.

[0115] In one embodiment, a CSI-RS resource set may include multiple CSI-RS resources. The CSI-RS resources are configured by NZP-CSI-RS-Resource signaling.

[0116] Figure 2 A schematic diagram of CSI-ReportConfig according to an embodiment of the present disclosure is shown.

[0117] In one embodiment, `reportConfigType` is configured in the CSI reporting configuration. `reportConfigType` indicates the time-domain behavior of the CSI reporting configuration. The time-domain behavior can be periodic, `semiPersistentOnPUCCH`, `semiPersistentOnPUSCH`, or non-periodic.

[0118] In one embodiment, the periodic CSI reporting configuration is effective after it has been configured via RRC (Radio Resource Control) signaling.

[0119] In one embodiment, if the UE receives MAC CE (Media Access Control Unit) signaling that activates the semi-persistentOnPuCCH CSI report configuration, then the semi-persistentOnPuCCH CSI report configuration is valid.

[0120] In one embodiment, the semi-persistentOnPUSCH CSI reporting configuration is valid if the UE receives a DCI indicating a trigger state associated with the semi-persistentOnPUSCH CSI reporting configuration.

[0121] In one embodiment, the aperiodic CSI reporting configuration is triggered when the UE receives a DCI indicating a triggering state associated with the aperiodic CSI reporting configuration.

[0122] In one embodiment, the RRC signaling `semiPersistentOnPUSCH-TriggerStateList` or `CSI-SemiPersistentOnPUSCH-TriggerStateList` is configured. This signaling includes a list of CSI reporting configurations configured with `semi-persistentOnPUSCH`. The DCI can be used to indicate one of these `semi-persistentOnPUSCH` CSI reporting configurations.

[0123] In one embodiment, the RRC signaling aperiodicTriggerStateList or CSI-AperiodicTriggerStateList is configured. This signaling includes associatedReportConfigInfoList, each of which contains a list of CSI-AssociatedReportConfigInfo associated with the aperiodic CSI reporting configuration. The DCI can be used to indicate one of the associatedReportConfigInfoLists. That is, the DCI can indicate a list of aperiodic CSI reporting configurations.

[0124] The number of CSI-RS ports (hereinafter referred to as CSI-RS ports) is configured by nrofPorts in CSI-ResourceMapping, which is associated with NZP-CSI-RS-Resource. nrofPorts can be one of the following: p1, p2, p4, p8, p12, p16, p24, p32 (e.g., integers 1, 2, 4, 8, 12, 16, 24, and 32). That is, p1 indicates that the number of CSI-RS ports is 1, p2 indicates that the number of CSI-RS ports is 2, and so on.

[0125] If the number of base station antennas changes, the channel can change, and the number of CSI-RS ports may also need to change. For example, a base station with four antennas can support four-port CSI-RS. If the number of antennas is reduced to two, the base station cannot support four-port CSI-RS. In one embodiment, it would be beneficial if the UE could provide channel measurements for different numbers of antenna ports. However, most CSI-RS resource settings and CSI reporting configurations are configured by RRC signaling. Furthermore, DCI can only trigger aperiodic CSI reporting configurations. That is, the BS cannot quickly change the CSI reporting configuration based on changes in the number of BS antennas. In this disclosure, a dynamic method for changing the CSI reporting configuration is provided.

[0126] Figure 3 A flowchart of a method according to an embodiment of the present disclosure is shown. Figure 3 The method shown can be used in a UE and includes the following steps:

[0127] Step 301: Receive high-level signaling from the BS, including CSI report configuration information.

[0128] Step 302: Receive the first signaling from the BS, including a CSI report trigger status indication and / or a pattern indication.

[0129] Step 303: Perform CSI report based on RRC signaling and / or first signaling.

[0130] Specifically, the UE can receive higher-level signaling that includes CSI report configuration information. The higher-level signaling can be MAC CE signaling or RRC signaling. In some embodiments, the higher-level signaling includes at least one of the following: CSI report configuration, CSI-RS resource configuration, or trigger status list.

[0131] In some embodiments, CSI-RS resource configuration may include at least one of the following: CSI-ResourceConfig, NZP (Non-Zero Power) CSI-RS (CSI Reference Signal) resource set, NZP CSI-RS resource, CSI-RS resource mapping, ZP-CSI-RS-ResourceSet, or ZP-CSI-RS-Resource.

[0132] In some embodiments, the trigger state list includes one or more trigger states. Each trigger state may be associated with one or more CSI reporting configurations. The trigger states(s) in the trigger state list may be associated with one or more CSI reporting configurations configured with different time-domain behaviors (e.g., time-domain behaviors configured in the reportConfigType signaling). For example, time-domain behaviors include periodic, semi-persistent, semiPersistentOnPUCCH, semiPersistentOnPUSCH, or non-periodic.

[0133] Figure 4 A schematic diagram of a trigger state list according to an embodiment of the present disclosure is shown. Figure 4 The trigger status list includes trigger status 1 associated with non-periodic CSI reporting configuration 1 and trigger status 2 associated with semi-persistent CSI reporting configuration 1.

[0134] Figure 5 A schematic diagram of a list of trigger states according to an embodiment of the present disclosure is shown. Figure 5 The list of trigger states shown includes trigger state 1 and trigger state 2. In this embodiment, trigger state 1 is associated with non-periodic CSI reporting configuration 1 and semi-persistent CSI reporting configuration 1 on PUCCH, and trigger state 2 is associated with semi-persistent CSI reporting configuration 1, non-periodic CSI reporting configuration 2 and non-periodic CSI reporting configuration 3 on PUSCH.

[0135] In some embodiments, the trigger status list includes one or more trigger states, and each trigger state may be associated with one or more periodic CSI report configurations. For example, Figure 6 The list of trigger states shown includes trigger state 1 associated with periodic CSI reporting configuration 1 and trigger state 2 associated with periodic CSI reporting configuration 2.

[0136] In one embodiment, the trigger state list includes one or more trigger states, and each trigger state is associated with one or more periodic CSI reporting configurations that are triggered to be active / valid, while other periodic CSI reporting configurations associated with non-triggered trigger states are not triggered to be deactivated / invalid.

[0137] In one embodiment, the trigger status list includes one or more trigger states, and each trigger state is associated with one or more periodic CSI reporting configurations. Whether a periodic CSI reporting configuration configured in the trigger status list is valid, and / or triggered, and / or active is determined based on a first signaling. When the periodic CSI reporting configuration is configured in csi-ReportConfigToAddModList, a periodic CSI reporting configuration not included in the trigger status list is valid. In other words, periodic CSI reporting configurations not included in the trigger status list are not controlled by the first signaling. In some embodiments, the status (e.g., active or inactive) of other CSI reporting configurations in the trigger status list but not indicated by the first signaling does not change.

[0138] In some embodiments, the trigger state list includes one or more subsets of the trigger state list. In one embodiment, the subset trigger state list includes at least one of the following:

[0139] - List of non-periodic trigger states,

[0140] - List of periodically triggered states

[0141] - List of semi-persistent trigger states,

[0142] -List of semi-persistent trigger states on PUSCH, or

[0143] - List of semi-persistent trigger states on PUCCH.

[0144] Note that each subset of the trigger state list can be associated only with CSI report configurations that have the same kind of time-domain behavior (e.g., periodic, aperiodic, semi-persistent, etc.).

[0145] In one embodiment, triggering trigger state X means triggering trigger state X in each subset of triggers, where X is an index. In another embodiment, triggering trigger state X means triggering the Xth trigger state in each subset of trigger state lists. In an embodiment where the Xth trigger state is triggered, if a subset of trigger state lists does not include trigger state X, then the trigger state in the subset of trigger state lists will not be triggered.

[0146] Figure 7 A schematic diagram of a trigger state list according to an embodiment of the present disclosure is shown. The trigger state list includes a periodic trigger state list, a semi-persistent trigger state list, and a non-periodic trigger state list. The periodic trigger state list includes trigger state 1 associated with periodic CSI reporting configuration 1, trigger state 2 associated with periodic CSI reporting configuration 2, and so on. The semi-persistent trigger state list includes trigger state 1 associated with semi-persistent CSI reporting configuration 1, trigger state 2 associated with semi-persistent CSI reporting configuration 2, and so on. The non-periodic trigger state list includes trigger state 1 associated with non-periodic CSI reporting configuration 1, trigger state 2 associated with non-periodic CSI reporting configuration 2, and so on.

[0147] In some embodiments, the trigger status list includes two types of trigger status lists, one of which includes at least one of the following: a CSI trigger status report on the PUCCH or a CSI trigger status report on the PUSCH.

[0148] In one embodiment, the CSI trigger status report on the PUCCH is associated with a periodic CSI reporting configuration and / or a semi-persistentOnPUCCH CSI reporting configuration.

[0149] In one embodiment, CSI trigger status reporting on the PUSCH is associated with a semi-persistentOnPUSCH CSI reporting configuration and / or an aperiodic CSI reporting configuration.

[0150] In one embodiment, a time offset is triggered when a CSI trigger status report is triggered on the PUSCH.

[0151] In some embodiments, a periodic or semi-persistentOnPUCCH CSI reporting configuration may be configured with one or more PUCCH resources (e.g., PUCCH-CSI resources). A PUCCH resource is a resource on which CSI reports can be sent. In one embodiment, the PUCCH resources of a periodic or semi-persistentOnPUCCH CSI reporting configuration in the same trigger state are identical. Alternatively or supplementally, the PUCCH resources of a periodic or semi-persistentOnPUCCH CSI reporting configuration in different trigger states are identical.

[0152] In some embodiments, each trigger state may be associated with one or more CSI reporting configurations configured with a codebook configuration (e.g., CodebookConfig). In one embodiment, the number of antenna ports (e.g., nrOfAntennaPorts) of CSI reporting configurations associated with the same trigger state is the same. In some embodiments, the number of antenna ports (e.g., nrOfAntennaPorts) of CSI reporting configurations configured with different trigger states is different.

[0153] In some embodiments, each trigger state may be associated with at least one of the following: one or more CSI report configurations, one or more TCI (Transmission Configuration Indicator) states, one or more CSI-RS resource configurations, a first time offset, a first time offset index, a second time offset, a second time offset index, a difference in power control offset, a power control offset, a power control offset SS (synchronization signal), a difference in the number of ports, a repetition count, and a number of ports.

[0154] In one embodiment, the TCI state is used for a first time-domain behavior CSI-RS resource configuration associated with the triggered CSI report configuration. The first time-domain behavior includes at least one of semi-persistent or aperiodic behavior. In another embodiment, the first time-domain behavior includes at least one of periodic, semi-persistent, or aperiodic behavior. Semi-persistent behavior includes semi-persistentOnPUCCH and / or semi-persistentOnPUSCH.

[0155] In one embodiment, the TCI state is used for a first-purpose CSI-RS resource configuration associated with the triggered CSI report configuration. For example, the first purpose includes at least one of channel measurement and intra-cell interference measurement.

[0156] In one embodiment, a trigger state is associated with a TCI state. In one embodiment, the TCI state is used for all CSI reporting configurations associated with the trigger state, which is associated with a first purpose of the CSI-RS resource configuration and / or with a first time-domain behavior.

[0157] In one embodiment, the TCI state is used for all CSI-RS resource configurations associated with the trigger state.

[0158] In one embodiment, the TCI status is used for the semi-persistent CSI-RS resource configuration associated with the triggered CSI report configuration.

[0159] In one embodiment, the TCI status is used for semi-persistent CSI-RS resource configuration and non-periodic CSI-RS resource configuration associated with the triggered CSI reporting configuration.

[0160] In one embodiment, the TCI status is used for semi-persistent CSI-RS resource configuration and periodic CSI-RS resource configuration associated with the triggered CSI reporting configuration.

[0161] In one embodiment, the first time offset indicates the offset between the signaling that triggers the trigger state and the time slot in which the UE can report CSI according to the CSI report configuration associated with the triggered trigger state. In one embodiment, the first time offset indicates the offset between two CSI reports. If the first time offset is configured in the trigger state list, the first time offset or the list of first time offsets configured in the CSI report configuration associated with the trigger state list (i.e., the list of first time offsets) can be ignored. In one embodiment, the trigger state is associated with the first time offset.

[0162] In one embodiment, the first time offset index indicates the first time offset in the first time offset list configured in the CSI report configuration.

[0163] In one embodiment, the first time offset (value) configured for the CSI report configuration in the trigger status list is less than a threshold. For example, the threshold is an integer value greater than 0 and less than 8.

[0164] In one embodiment, the second time offset indicates the offset between the signaling that triggers the trigger state and the time slot in which the UE receives CSI-RS. In one embodiment, the second time offset is indicated by indicating a second time offset index in a second time offset list (i.e., a list of second time offsets) configured in the CSI-RS resource configuration.

[0165] In one embodiment, the difference (P_delta) in the power control offset indicates a change in the power control offset. The power control offset (P) used by the UE for CSI reporting is determined by the power control offset (P_1) configured in the associated CSI-RS resource configuration and the difference (P_delta) in the power control offset. For example, P = P_1 - P_delta. The power control offset can be PowerControlOffset or PowerControlOffsetSS configured in the NZP-CSI-RS-Resource signaling.

[0166] In one embodiment, power control offset refers to powerControlOffset, which is the assumed ratio of PDSCH EPRE (energy per resource unit) to NZP (non-zero power) CSI-RS EPRE when the UE obtains CSI feedback / report.

[0167] In one embodiment, power control offset SS refers to powerControlOffsetSS, which is the assumed ratio of NZP CSI-RSEPRE to SSB (SS / PBCH block)EPRE.

[0168] In one embodiment, the port number difference is used to determine the number of ports the UE assumes is used for calculating CSI or CSI-RS resource configurations. For example, the UE is triggered by an indicated trigger state to perform CSI reporting, with the number of ports configured for the CSI-RS resources associated with the CSI reporting being PN_1, and the port number difference being PN_2. In this case, the number of ports the UE uses to calculate CSI is PN = PN_1 - PN_2 or PN = PN_1 + PN_2. Alternatively, the port number difference is a scaling factor PN_3 of the port number PN_1. For example, PN = PN_1 / PN_3 or PN = PN_1 * PN_3. The time and / or frequency resources used for the port number PN are derived based on the configured time and / or frequency resources. As another example, the UE is triggered by an indicated trigger state to perform CSI reporting, with the number of ports configured for the CSI reporting configuration being PN_1, and the port number difference being PN_2. In this case, the number of ports PN used by the UE to calculate or report CSI or PMI (Precoding Matrix Indicator) is PN = PN_1 - PN_2 or PN = PN_1 + PN_2. Alternatively, the difference in the number of ports is a scaling factor PN_3 of the number of ports PN_1 (e.g., PN = PN_1 / PN_3, PN = PN_1 * PN_3).

[0169] In one embodiment, the repetition count indicates the number of times the CSI-RS is repeated in the time domain. For example, the CSI-RS is repeated multiple times in the time domain, and the repetition count of the CSI-RS is indicated by the repetition count included in the CSI report configuration information. The first version of the CSI-RS is configured by RRC signaling, and the next repetition version begins at the Xth time slot after the previous CSI-RS resource ends, where X is an integer (e.g., X = 1).

[0170] In some embodiments, the CSI report configuration may be associated with more than one higher-layer signaling resourceForChannelMeasurement or more than one higher-layer signaling nzp-CSI-RS-ResourcesForinterference. In some embodiments, the CSI report configuration may be associated with more than one CSI-RS resource setting for channel measurements. In some embodiments, the CSI report configuration may be associated with more than one CSI-RS resource setting for interference measurements.

[0171] In some embodiments, the trigger status list includes multiple trigger statuses. Each trigger status is associated with one or more CSI reporting configurations.

[0172] In one embodiment, the trigger state list includes multiple trigger states, and each trigger state is associated with one or more CSI reporting configurations, with the same number of ports for the CSI-RS resource configurations associated with the CSI reporting configurations within a trigger state.

[0173] In one embodiment, the trigger state list includes multiple trigger states, and each trigger state is associated with one or more CSI reporting configurations, wherein the time and / or frequency resources of the CSI-RS resource configuration associated with the CSI reporting configuration in the first trigger state are a subset of the frequency and / or time resources of the CSI-RS resource configuration associated with the CSI reporting configuration in the second trigger state.

[0174] In one embodiment, the trigger state list includes multiple trigger states, and each trigger state is associated with one or more CSI reporting configurations. The powerControlOffset / powerControlOffsetSS of the CSI-RS resource configuration associated with the CSI reporting configuration in the first trigger state is less than the powerControlOffset / powerControlOffsetSS of the CSI-RS resource configuration associated with the CSI reporting configuration in the second trigger state. In this embodiment, the number of ports of the CSI-RS resource configuration associated with the CSI reporting configuration in the second trigger state may be greater than the number of ports of the CSI-RS resource configuration associated with the CSI reporting configuration in the first trigger state.

[0175] In some embodiments, the CSI report configuration in the trigger status list is specifically designed.

[0176] For example, the specific design of the CSI report configuration in the trigger status list can be based on at least one of the following embodiments of parameters / elements in the CSI report configuration in the trigger status list.

[0177] In one embodiment, the trigger offset list in the CSI report configuration may be configured with only one trigger offset.

[0178] In one embodiment, the list of report offsets associated with the trigger state in the CSI report configuration is configured with only one report offset value.

[0179] In one embodiment, a first report type for CSI reporting configuration can be configured. For example, the first report type includes at least one of the following: cri-RI-i1, cri-RI-i1-CQI, cri-Ri-CSI, cri-RSRP; the report type includes: none, cri-RI-i1, cri-RI-i1-CQI, cri-Ri-CSI, cri-RSRP, cri-RI-PMI-CQI, ssb-Index-RSRP, cri-RI-LI-PMI-CQI.

[0180] In one embodiment, the higher-layer parameter timeRestrictionForChannelMeasurements in the CSI report configuration is configured to 'configured'. Note that if the higher-layer parameter timeRestrictionForChannelMeasurements in CSI-ReportConfig is set to 'configured', the UE should only use the most recent (no later than the CSI reference resource) timing of the NZP CSI-RS associated with the CSI resource settings to calculate the channel measurements of the CSI reported in uplink slot n.

[0181] In one embodiment, the CSI-RS resource associated with the CSI reporting configuration is specifically designed. For example, the CSI-RS resource may be specifically designed as at least one of the following:

[0182] -CSI-RS resource configuration is associated with a first time-domain behavior: in one embodiment, the first time-domain behavior includes at least aperiodicity;

[0183] - The aperiodicTriggeringOffset configured in the CSI-RS resource configuration associated with the triggering state, or with a CSI report configuration in the triggering state, is configured with only one aperiodic trigger offset value. Note that the aperiodic trigger offset value indicates the time offset between the DCI and the CSI-RS resource.

[0184] In some embodiments, CSI reporting configurations in the trigger status list are invalid before being triggered. For example, a CSI reporting configuration in the trigger status list may be activated / valid only when a triggering CSI reporting configuration / a trigger status associated with the CSI reporting configuration (indicating / including a first signaling of the trigger status) is received.

[0185] In one embodiment, the periodic CSI reporting configuration can be active / active once it is configured.

[0186] In one embodiment, when the UE receives an activation MACCE for the semi-persistent CSI reporting configuration on the PUCCH, the semi-persistent CSI reporting configuration on the PUCCH is valid / active.

[0187] In one embodiment, when the UE receives a DCI indicating a trigger state, if the semi-persistent reporting configuration or a non-periodic CSI reporting configuration on the PUSCH is active, the trigger state triggers the reporting configuration. In one embodiment, a trigger state list can be used to deactivate the trigger state.

[0188] In some embodiments, a periodic CSI reporting configuration may be associated with a non-periodic CSI reporting configuration or a semi-persistent CSI reporting configuration. If a non-periodic CSI reporting configuration or a semi-persistent CSI reporting configuration is triggered, the associated periodic CSI reporting configuration is also triggered.

[0189] In some embodiments, a periodic CSI reporting configuration can be associated with a trigger state in a trigger state list. If a trigger state is triggered, the associated periodic CSI reporting configuration is also triggered. The trigger state list can be configured by semiPersistentOnPUSCH-TriggerStateList, CSI-SemiPersistentOnPUSCH-TriggerStateList, aperiodicTriggerStateList, CSI-AperiodicTriggerStateList, associatedReportConfigInfoList, or CSI-AssociatedReportConfigInfo.

[0190] In some embodiments, a semi-persistent CSI reporting configuration can be associated with a trigger state in a trigger state list. If a trigger state is triggered, the associated periodic CSI reporting configuration is also triggered. The trigger state list can be configured by aperiodicTriggerStateList, CSI-AperiodicTriggerStateList, associatedReportConfigInfoList, or CSI-AssociatedReportConfigInfo.

[0191] In some embodiments, trigger states in a first trigger state list are configured to be associated with trigger states in a second trigger state list. The second trigger state list can be aperiodicTriggerStateList, CSI-AperiodicTriggerStateList, associatedReportConfigInfoList, asemiPersistentOnPUSCH-TriggerStateList, or CSI-SemiPersistentOnPUSCH-TriggerStateList. If a trigger state in the second trigger state list is triggered, the associated trigger state in the first trigger state list is also triggered.

[0192] In some embodiments, a semi-persistent CSI reporting configuration can be (configured to) be associated with a non-periodic CSI reporting configuration. If a non-periodic CSI reporting configuration is triggered, the associated semi-persistent CSI reporting configuration is also triggered.

[0193] In some embodiments, the trigger states in the trigger state list are configured to be associated with a non-periodic CSI reporting configuration or a semi-persistent CSI reporting configuration. If a non-periodic CSI reporting configuration or a semi-persistent CSI reporting configuration is triggered, then the CSI reporting configuration(s) in the associated trigger state are also triggered.

[0194] In some embodiments, if a CSI reporting configuration in a triggered state is triggered to be valid, the CSI-RS resource (configuration) associated with the CSI reporting configuration is also valid.

[0195] In some embodiments, if a CSI reporting configuration in a triggered state is triggered to be valid, then some or all of the CSI-RS resources in the CSI-RS resource configuration associated with the triggered CSI reporting configuration are also valid.

[0196] Figure 8 A schematic diagram of a trigger state list according to an embodiment of the present disclosure is shown. Figure 8 The trigger status list includes trigger status 1 associated with periodic CSI reporting configuration 1 and trigger status 2 associated with semi-persistent CSI reporting configuration 1. When periodic CSI reporting configuration 1 is triggered (or trigger status 1 is indicated / triggered by the first signaling), some or all of the CSI-RS resources in the CSI-RS resource configuration associated with periodic CSI reporting configuration 1 are also valid / triggered. Similarly, when semi-persistent CSI reporting configuration 1 is triggered (or trigger status 2 is triggered / indicated by the first signaling) and is valid, some or all of the CSI-RS resources in the CSI-RS resource configuration associated with semi-persistent CSI reporting configuration 1 are also valid.

[0197] In one embodiment, a CSI-RS resource configuration includes one or more CSI-RS resource sets, and a CSI-RS resource set includes one or more CSI-RS resources.

[0198] In one embodiment, the portion of the CSI-RS resource in the CSI-RS resource configuration that is effective when the associated CSI reporting configuration is triggered is a first type of CSI-RS resource in the CSI-RS resource configuration. For example, the first type of CSI-RS resource includes a CSI-RS resource configured with a number of ports that is less than or equal to the number of ports associated with the triggered state. Alternatively or supplementarily, the first type of CSI-RS resource includes CSI-RS resources that are not configured with trs-info (tracking reference signal information) and / or repeat (information).

[0199] In some embodiments, the first signaling includes at least one of the following: activation / deactivation indication, trigger status indication, TCI indication, first time offset, first time offset index, power control offset difference, power control offset indication, pattern indication, port number difference, repetition count, CSI report configuration ID (identifier), port number indication, second time offset, second time offset index, and start new CSI calculation indication. In some embodiments, the information included in the first signaling is a CSI report trigger status indication.

[0200] In one embodiment, the first time offset is the offset between the first signaling and the time slot of the PUSCH in which the UE reports CSI. In some embodiments, the first time offset is the offset between two CSI reports.

[0201] In one embodiment, the power control offset may be a power control offset or a power control offset SS. In one embodiment, the power control offset indication specifies a power control offset used to replace the original power control offset for a CSI-RS resource associated with a triggered CSI report configuration.

[0202] In one embodiment, the pattern indicator indicates the valid patterns in the table. For example, the table could be:

[0203]

[0204]

[0205]

[0206] The parameters k and l in the table are configured by higher-level signaling.

[0207] In one embodiment, a pattern indicator can indicate a set of predefined patterns for CSI-RS locations within a defined time slot. Each pattern is a row in the table above. For example, a pattern indicator can indicate that rows (with row indices) 14, 15, 16, 17, and 18 are invalid. That is, the CSI reporting configuration or CSI-RS resource associated with the indicated row is invalid.

[0208] In one embodiment, a pattern indicator indicates a row (index) in a table to indicate whether a pattern in a row having that row index is valid or invalid. In one embodiment, a pattern indicator indicates a maximum row index, wherein a pattern in a row of the table with a row index less than or equal to the maximum row index is valid, while a pattern in a row with a row index greater than the maximum row index is invalid. In one embodiment, a pattern indicator indicates an invalid pattern. In one embodiment, a pattern indicator indicates a pattern index to indicate whether a pattern having the indicated pattern index or a row having the indicated pattern index is valid or invalid.

[0209] In one embodiment, each CSI report configuration is associated with a CSI report configuration ID.

[0210] In one embodiment, the port count indicator may indicate the maximum number of valid ports of the CSI-RS resource associated with the CSI reporting configuration.

[0211] In one embodiment, the Start New CSI Calculation Instruction instructs the UE to remeasure and / or recalculate the CSI. In other words, the UE does not report the CSI generated / determined / measured / calculated according to the CSI-RS resource until it receives the instruction (e.g., the first signaling).

[0212] In one embodiment, the activation / deactivation indicator indicates whether to trigger / activate the CSI reporting configuration associated with the indicated trigger state, or whether to release / deactivate the CSI reporting configuration associated with the indicated trigger state.

[0213] In one embodiment, the activation / deactivation instruction activates / deactivates the CSI report configuration.

[0214] In some embodiments, the first signaling may indicate at least one or more trigger status indications. In one embodiment, each trigger status includes one or more CSI reporting configurations and a TCI status. The TCI status indicates the TCI status of the CSI-RS resource associated with the CSI reporting configuration.

[0215] In some embodiments, the first signaling is / includes a MAC CE and / or a DCI. The MAC CE may be used to select M trigger states from a list of trigger states configured by higher-layer signaling (e.g., RRC signaling), where M is an integer value greater than 0 and not greater than a threshold (e.g., 8). The DCI may be used to indicate one of the trigger states selected by the MAC CE.

[0216] In some embodiments, the first signaling is / includes DCI.

[0217] In embodiments where the first signaling includes / is a DCI, the DCI is a UE-specific DCI (e.g., DCI format 0-1 or DCI format 0-2).

[0218] In one embodiment, fields in the DCI are used to indicate at least one of the information (e.g., the parameters mentioned above included in the first signaling).

[0219] In embodiments where the first signaling includes / is a DCI, fields in the DCI are used to indicate information associated with a triggering state. For example, this field is a CSI request field. Furthermore, the DCI can be used to trigger a non-periodic CSI reporting configuration or a semi-persistentOnPUSCH CSI reporting configuration. Indications in the DCI can also trigger periodic CSI reporting configurations or semi-persistent CSI reporting configurations, which are configured to be associated with a non-periodic CSI reporting configuration or a semi-persistentOnPUSCH CSI reporting configuration, or with a triggering state that is the triggered state.

[0220] In embodiments where the first signaling includes / is a DCI, the first signaling indicates more than one piece of information (e.g., the parameters mentioned above included in the first signaling), and this information may be indicated in different fields. In this embodiment, some information may be indicated individually in different fields. Alternatively or supplementarily, some information may be indicated together in the same field. For example, a trigger status indication included in the DCI may be indicated in one field, and a time offset included in the DCI may be indicated in another field.

[0221] In embodiments where the first signaling includes / is a DCI, the DCI triggers a CSI trigger status report on the PUCCH, wherein one field of the DCI is used to indicate a trigger status indication, and another field of the DCI is used to indicate a time offset. For example, the DCI that triggers a CSI trigger status report on the PUSCH includes one field configured to indicate a trigger status indication and another field configured to indicate a time offset.

[0222] In embodiments where the first signaling includes / is DCI, if the DCI trigger includes a trigger state of either a non-periodic CSI reporting configuration or a semi-persistentOnPUSCH CSI reporting configuration, then the DCI includes a field for indicating the trigger state indication and a field for indicating the time offset.

[0223] In embodiments where the first signaling includes / is a DCI, the first signaling may include a first DCI and a second DCI, wherein the first DCI may include a field for indicating a trigger status indication, and the second DCI may include a field for indicating a trigger status indication and a field for indicating a time offset.

[0224] In embodiments where the first signaling includes / is a DCI, the DCI may be a group common DCI. A group common DCI refers to a DCI that carries information for one or more UEs, and / or indicates that fields in the DCI are used to indicate information for one or more UEs. Note that in this disclosure, considerations that apply to UE-specific DCIs in this disclosure (e.g., the design of fields, rules, and methods) may also apply to group common DCIs.

[0225] In embodiments where the first signaling includes / is a DCI, the information in the DCI may be indicated by a bitmap or code points.

[0226] For example, this information can be indicated by a bitmap. The information indicated by the bitmap can be a trigger state activation / deactivation indicator. Each bit in the bitmap corresponds to a trigger state, where bit '0' indicates that the corresponding trigger state is deactivated, and bit '1' indicates that the corresponding trigger state is activated.

[0227] For example, this information can be indicated by code points. Each code point indicates a trigger state. If the trigger state is indicated by a code point included in the first signaling, then the trigger state is activated.

[0228] In embodiments where the first signaling includes / is a DCI, the fields in the DCI include bits indicating activation / deactivation indication and X bits indicating trigger status indication, where X is a positive integer. For example, an activation / deactivation indication bit of '1' indicates that the DCI (e.g., X bits) is used for activation indication, and '0' indicates that X bits are used for deactivation indication. Figure 9 A schematic diagram of a field in a DCI according to an embodiment of the present disclosure is shown. Figure 9 The DCI in the code can be a UE-specific DCI. For example... Figure 9 As shown, the fields in DCI include 1 bit indicating activation / deactivation and X bits indicating trigger status, where X is a positive integer. Figure 10 A schematic diagram of a field in a DCI according to an embodiment of the present disclosure is shown. Figure 10The DCI in the data can be a group-common DCI. Figure 10 In this field, there is one bit indicating activation / deactivation, X bits indicating the trigger status of UE 1, X bits indicating the trigger status of UE 2, etc.

[0229] In embodiments where the first signaling includes / is a group common DCI, the length of the trigger state indication field for different UEs (e.g., Figure 10 The trigger status indication for UE 1 and the trigger status indication for UE 2 can be different and / or configured by higher-layer signaling.

[0230] In embodiments where the first signaling includes / is a group common DCI, this field is shared by a group of UEs. In other words, it is the same indication associated with a CSI report for a group of UEs.

[0231] In one embodiment, the start position of the UE's trigger status indication field in the DCI is configured by higher-layer signaling.

[0232] In embodiments where the first signaling includes / is a group common DCI, a trigger status indication field can indicate the trigger status to a group of UEs.

[0233] In embodiments where the first signaling includes / is a group common DCI, the activation / deactivation indication is located at the beginning of the DCI (e.g., Figure 10 ).

[0234] In one embodiment, the first signaling is / includes broadcast DCI and / or multicast DCI. Broadcast or multicast DCI can be scrambled with at least one of the following RNTIs (Radio Network Temporary Identifiers): MCCH-RNTI (Multicast Broadcast Service (MBS) Control Channel RNTI), G-RNTI (Group RNTI), or G-CS-RNTI (Group Configuration Scheduling RNTI).

[0235] In embodiments where the first signaling includes / is DCI, the DCI is scrambled with a specific RNTI. For example, the specific RNTI is used only for CSI-RS configuration indication. In one embodiment, the CSI-RS configuration indication is the aforementioned parameter included in the first signaling.

[0236] In embodiments where the first signaling includes / is DCI, the DCI is scrambled with at least one of the following RNTIs: MCCH-RNTI, G-RNTI, or G-CS-RNTI.

[0237] In some embodiments, the first signaling includes / is a MAC CE.

[0238] In embodiments where the first signaling includes / is a MAC CE, the MAC CE is scheduled by a broadcast / multicast DCI.

[0239] In embodiments where the first signaling includes / is a MAC CE, the MAC CE includes at least one of the following fields:

[0240] - Trigger status indicator

[0241] - Activation / deactivation indicator

[0242] - A field indicating whether the indicated trigger state is activated or deactivated: for example, setting this field to 1 indicates activation, otherwise it indicates deactivation.

[0243] - Serving Cell ID: This field indicates the identifier / identifier of the serving cell to which MAC CE is applied.

[0244] -BWP ID, this field indicates the DL BWP to which MAC CE is applied.

[0245] - Trigger status list ID, indicating the list of trigger statuses that should be activated or deactivated.

[0246] -CSI report configuration ID, indicating CSI reports,

[0247] -TCI status,

[0248] -TCI status list

[0249] -First time offset

[0250] - Difference in power control offset

[0251] -Power control offset

[0252] -Drawing instructions

[0253] -Second time offset

[0254] - Difference in the number of ports

[0255] -Number of repetitions

[0256] - Port number indicator, or

[0257] - Initiate a new CSI calculation instruction.

[0258] The definitions of fields included in MAC CE can be found in the DCI for fields with the same names.

[0259] In one embodiment, the first signaling includes / is a SIB (System Information Block).

[0260] In one embodiment, the first signaling may differ for different trigger states. For example, the first signaling configured to indicate a CSI trigger state report on the PUCCH may be DCI, while the first signaling configured to trigger a CSI trigger state report on the PUSCH may be MAC CE. In one embodiment, the first signaling may differ for different lists of trigger states.

[0261] In some embodiments, if the UE receives a first signaling indicating a trigger state, and the trigger state is associated with at least a periodic CSI reporting configuration or a semi-persistent CSI reporting configuration, the UE may perform at least one of the following:

[0262] -Measurement of CSI-RS resource configuration associated with the periodic CSI reporting configuration triggered by the first signaling.

[0263] - Measurements of CSI-RS resource configurations associated with periodic CSI reporting configurations, which are triggered by the first signaling and associated with the lowest CSI report configuration ID (i.e., CSI-ReportConfigId).

[0264] -Measurement of CSI-RS resource configuration associated with the non-periodic CSI reporting configuration triggered by the first signaling.

[0265] - Measurement of CSI-RS resource configurations associated with non-periodic CSI reporting configurations, which are triggered by the first signaling and associated with the lowest CSI report configuration ID (i.e., CSI-ReportConfigId).

[0266] - Measurement of valid CSI-RS resource configurations associated with CSI reporting configurations, which are triggered by a first signaling for the first CSI report.

[0267] - Measurement of CSI-RS resource configuration, which is the first or most recent valid CSI-RS resource configuration after the first signaling is received or after an application delay (regardless of whether the CSI-RS resource is associated with a CSI reporting configuration, and regardless of whether the CSI-RS resource configuration is configured as 'aperiodic,' 'semi-persistent,' or 'periodic').

[0268] - Measurement of CSI-RS resource configuration, which is activated and associated with CSI reporting configuration triggered by the first signaling.

[0269] - Measurement of the CSI-RS resource configuration associated with the CSI reporting configuration triggered by the first signaling (if the CSI-RS resource configuration was not activated before receiving the first signaling, then the CSI-RS resource configuration is activated by the first signaling), or

[0270] - Measurement of CSI-RS resource configuration, which is the first or most recently valid CSI-RS resource configuration after the first signaling is received or after an application delay, wherein the CSI-RS resource configuration is associated with the CSI reporting configuration triggered by the first signaling.

[0271] In some embodiments, if the UE receives a first signaling indicating a trigger state, and the trigger state is associated with at least a periodic CSI reporting configuration or a semi-persistent CSI reporting configuration, then the aforementioned action is performed on the first CSI report after the UE receives the first signaling.

[0272] In some embodiments, if the UE receives a first signaling indicating a trigger state, and the trigger state is associated with at least a periodic CSI reporting configuration, the UE behavior may include at least one of the following:

[0273] - The UE reports CSI on the PUCCH, which is configured in the CSI reporting configuration. This CSI reporting configuration is triggered by the first signaling and is associated with the lowest CSI reporting configuration ID (i.e., CSI-ReportConfigId).

[0274] - The UE reports CSI on the PUCCH, which is configured in the CSI reporting configuration triggered by the first signaling.

[0275] - The UE reports CSI on the PUSCH, where the PUSCH is determined based on the CSI reporting configuration and the first signaling.

[0276] - If the first signaling indicates a time offset, the UE reports a CSI on the PUSCH.

[0277] - The UE reports CSI on the PUSCH, where the PUSCH is associated with a non-periodic or semi-persistentOnPUSCH CSI reporting configuration with the lowest index.

[0278] - The UE reports CSI on the PUCCH or PUSCH of the first or latest valid resource after receiving the first signaling, or after an application delay, or after the most recent valid CSI-RS resource, wherein the PUCCH or PUSH is associated with a CSI reporting configuration triggered by the first signaling, or

[0279] - The UE reports CSI on the UL resource of the first or latest valid resource after receiving the first signaling, or after an application delay, or after the latest valid CSI-RS resource, wherein the UL resource is associated with the CSI reporting configuration triggered by the first signaling.

[0280] In some embodiments, the UE measures / receives CSI-RS after a first application delay (also referred to as the first delay) following the receipt of the first signaling. For example, the first application delay is the duration between a time slot or last symbol and a first time slot / symbol in which the UE receives the first signaling and measures / receives CSI-RS based on the first signaling.
