摘要： A wireless device receives one or more messages comprising one or more configuration parameters. The one or more configuration parameters indicate a plurality of transmission configuration indication (TCI) states. comprise at least one configuration parameter of a first downlink transmission group and a second downlink transmission group. A medium access control control element (MAC CE) is received. The MAC CE comprises: a first field identifying one of the first downlink transmission group and the second downlink transmission group; and a second field activating one or more TCI states, of the plurality of TCI states, for a downlink transmission group identified by the first field. A downlink control information (DCI) scheduling a transport block is received. In response to receiving the DCI, the transport block based on a TCI state among the one or more TCI states of the downlink transmission group is received.

摘要： A wireless device receives one or more messages. The one or more messages comprise configuration parameters of a cell. The configuration parameters indicate: a plurality of slot format combinations of the cell; a plurality of reference signals (RS) of the cell; and a channel occupancy time (COT) radio network temporary identifier (RNTI). The wireless device receives a downlink control information (DCI) scrambled by the COT-RNTI indicating a slot format combination of the plurality of slot format combinations, for an RS of the plurality of RSs. A channel occupancy time (COT) structure is determined for the RS based on the slot format combination. A transport block is transmitted, via uplink resources of the cell, based on the COT structure.

摘要： A wireless device receives configuration parameters indicating one or more first RSs, on a first cell, as candidate RSs for a BFR procedure of a second cell. The wireless device triggers, in response to a number of beam failure instances on the second cell, the BFR procedure for the second cell. The first cell is deactivated. Based on the deactivating the first cell, the BFR procedure for the second cell is cancelled.

摘要： A wireless device receives configuration parameters of channel state information (CSI) resource configurations for a CSI report configuration. The CSI resource configurations comprise first CSI resource configurations associated with a first transmission reception point (TRP) and second CSI resource configurations associated with at least two second TRPs. The wireless device receives a command comprising a first field triggering the CSI report configuration and a second field indicating whether the CSI report configuration is associated with the first CSI resource configurations or the second CSI resource configurations. The wireless device transmits, based on the CSI report configuration and in response to the second field indicating the CSI report configuration is associated with the first CSI resource configurations. A CSI report comprises one or more first CSI quantities of the first TRP.

摘要： A wireless device monitors a first radio link quality on a first plurality of reference signals of a bandwidth part of a cell in a non-power-saving state. The wireless device detects at least a first synchronization status based on the monitoring the first radio link quality. The wireless device receives a downlink control information indicating transitioning from the non-power-saving state to a power saving state. The wireless device monitors, based on the downlink control information, a second radio link quality on a second plurality of reference signals of the bandwidth part. The wireless device detects at least a second synchronization status based on the monitoring the second radio link quality.

摘要： A wireless device may receive one or more messages comprising configuration parameters of a cell. A reference duration for contention window adjustment may be determined based on the configuration parameters. The reference duration may be from a beginning of a channel occupancy of a first transmission burst and until an end of a first slot. The at least one physical uplink shared channel (PUSCH) may be transmitted. A contention window value may be determined based on a plurality of new data indicators (NDIs) received in a plurality of uplink grants corresponding to a plurality of first transport blocks transmitted by the wireless device during the reference duration. The wireless device may perform a listen before talk procedure based on the contention window value. One or more second transport blocks may be transmitted based on the listen before talk procedure indicating a clear channel.

摘要： A wireless device receives one or more messages from a base station. The one or more messages comprise configuration parameters of a cell. The configuration parameters indicate: a plurality of slot format combinations of the cell; a channel occupancy time (COT) radio network temporary identifier (RNTI); and an index of a field in a downlink control information (DCI) for the cell. The DCI scrambled by the COT-RNTI is received. A COT structure, for the cell, is determined based on one of the plurality of slot format combinations indicated by the field in the DCI associated with the index. A transport block is transmitted, via the cell, on uplink resources according to the COT structure.

摘要： A wireless device receives one or more messages indicating a handover to a cell of a second base station. The one or more messages comprise configuration parameters of the cell. The configuration parameters indicate a plurality of power control parameter sets (PCPSs). The configuration parameters indicate a plurality of downlink reference signals. A downlink reference signal of the plurality of downlink reference signals is determined based on measurements of the plurality of downlink reference signals. A PCPS is selected from the plurality of PCPSs. The PCPS is associated with the downlink reference signal. An uplink transmission power is determined, based on the PCPS, for a physical uplink shared channel (PUSCH) of the cell. An uplink transport block is transmitted with the uplink transmission power via the PUSCH of the cell.
