摘要： A wireless device receives one or more messages comprising spatial relation configuration parameters of a physical uplink control channel. The configuration parameters indicate a plurality of reference signal (RS) sets. An RS set of the plurality of RS sets comprises one or more RSs. A medium access control control element, activating the RS set of the plurality of RS sets, is received. A downlink control information, indicating an RS of the RS set, is received. A spatial domain transmission filter, for the physical uplink control channel, is determined based on based on the RS. Uplink control information is transmitted, via the physical uplink control channel, based on the spatial domain transmission filter.

摘要： A wireless device receives one or more radio resource control message comprising configuration parameters of a plurality of cells. An activation command indicating activation of a plurality of secondary cells (SCells) of the plurality of cells is received. A first downlink control information (DCI), comprising a power saving indication bitmap, is received. Each bit of the power saving indication bitmap indicates whether to monitor a downlink control channel on a corresponding activated SCell of the plurality of SCells. The wireless device starts monitoring a downlink control channel of an activated SCell of the activated SCells, in response to a bit, of the power saving indication bitmap, corresponding to the activated SCell, indicating monitoring the downlink control channel. A second DCI is received via the downlink control channel.

摘要： A wireless device receives one or more radio resource control messages from a base station. The one or more radio resource control messages comprising configuration parameters of a cell for beam failure recovery. The configuration parameters indicate: a serving beam set, a plurality of candidate beam sets, and a monitoring priority of the plurality of candidate beam sets. A beam failure instance of the serving beam set is detected. In response to the detection, a first candidate beam set of the plurality of candidate beam sets is determined based on the monitoring priority. A candidate beam is selected from the first candidate beam set. A preamble associated with the candidate beam for the beam failure recovery is transmitted.

摘要： A wireless device selects a first a synchronization signal block (SSB), among SSBs of a cell, based on a signal quality measurement of the SSBs, and a second SSB, of the SSBs, based on the first SSB and a multiplexing pattern. The wireless device determines, based on the first SSB and the second SSB, monitoring occasions associated with a control resource set (coreset) to receive repetitions of downlink control information (DCI). The wireless device receives, via the determined monitoring occasions, one or more of the repetitions of the DCI.

摘要： A wireless device receives, from a base station, configuration parameters indicating a plurality of first reference signals (RSs) including a first RS associated with a plurality of second RSs. Based on signal strengths of the plurality of first RSs, the first RS is selected from the plurality of first RSs. Based on signal strengths of the plurality of second RSs, a second RS is selected from the plurality of second RSs associated with the first RS. Based on the selected second RS, the wireless device transmits a random access preamble.

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.

摘要： A wireless device receives one or more radio resource control messages comprising configuration parameters for a cell. The configuration parameters indicate a plurality of coreset groups corresponding to a plurality of transmission and reception points (TRPs). Each coreset in the plurality of coreset groups is associated with a transmission configuration indicator (TCI) state. A coreset group of the plurality of coreset groups is selected for a radio link monitoring of the cell. The selection is in response to the coreset group comprising a coreset with a pre-defined index value. One or more reference signals are monitored based on one or more TCI states of one or more coresets of the coreset group.
