    摘要: Embodiments of the present application are related to a method and apparatus for beam determination. An exemplary method includes: receiving configuration information at least indicating two failure detection resource sets in a cell; transmitting failure recovery information at least indicating a radio link quality of all failure detection resources in a first failure detection resource set of the two failure detection resource sets is worse than a first threshold; and monitoring physical downlink control channels (PDCCH)s in a control resource set (CORESET) in the cell based on the failure recovery information, wherein one or more transmission configuration indicator (TCI) states are activated for the CORESET and one TCI state of the one or more TCI states is associated with the first failure detection resource set, after a number of symbols from a last symbol of a received PDCCH for confirming the failure recovery information.

    摘要: Methods and apparatuses for beam reporting for non-serving cells are disclosed. A method comprises receiving a configuration of one or multiple CMR sets for channel measurement associated with a CSI-ReportConfig IE with reportQuantity set to ‘cri-RSRP’ or ‘ssb-Index-RSRP’, and nrofReportedRS-Neighboring indicating the number K of beams associated with non-serving cell(s), K is 1 or more; and transmitting a CSI report including K CRIs or SSBRIs and the measured L1-RSRP value of the resource associated with a non-serving cell indicated by each of the K CRIs or SSBRIs.

    摘要: Apparatus and methods of enhanced CSI-RS resource configuration and transmission for simultaneous UE Rx beam refinement are disclosed. The apparatus includes: a receiver that receives Channel State Information Reference Signal (CSI-RS) configuration comprising one or more CSI-RS resource sets for Receive (Rx) beam refinement, the CSI-RS resource sets comprising a plurality of CSI-RS resources for transmission of a plurality of CSI-RSs that are Frequency-Division Multiplexed (FDMed), wherein the receiver further receives, simultaneously, the CSI-RSs based on one or more Quasi Co-Location (QCL) assumptions; a processor that performs a simultaneous Rx beam refinement corresponding to the CSI-RSs that are FDMed; and a transmitter that transmits a reporting according to a Channel State Information (CSI) reporting configuration.

    摘要: Methods and apparatuses for triggering an aperiodic SRS are disclosed. A method comprises receiving a RRC signaling configuring N triggering offsets for each of P aperiodic SRS resource sets, where N is 1 or more, P is 1 or more; receiving a MAC CE to activate one or more triggering offset(s) among all configured triggering offsets for each of M out of the P aperiodic SRS resource sets, where M is 1 to P; receiving a DCI containing a non-zero SRS request field triggering at least one aperiodic SRS resource set, wherein at least one triggering offset of each triggered aperiodic SRS resource set is activated by the MAC CE; and transmitting SRS resources contained in each triggered aperiodic SRS resource set in the first available slot among all candidate slots indicated by the activated triggering offsets for each triggered aperiodic SRS resource set.
