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 configuration parameters indicating a first PDSCH processing capability value associated with a first power state of a cell, and a second PDSCH processing capability value associated with a second power state of the cell. The first PDSCH processing capability value indicates a first applicable gap between receiving a TB and transmitting an acknowledgement when the cell is in the first power state. The second PDSCH processing capability value indicates a second applicable gap between receiving a TB and transmitting an acknowledgement when the cell is in the second power state. A first TB is processed based on the first PDSCH processing capability value, when the cell in the first power state. A command is received indicating transitioning to the second power state. A second TB is processed based on the second PDSCH processing capability value, in response to transitioning to the second power state.

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 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 one or more messages. The one or more messages comprise configuration parameters of the cell. The configuration parameters indicate a plurality of control resource sets for multiple transmission reception points. Downlink control information (DCI) is received via a control resource set of the plurality of control resource sets. The DCI comprises a physical uplink control channel (PUCCH) resource indicator. The control resource set comprises one or more control channel elements starting from a first control channel element. A PUCCH resource is determined based on the PUCCH resource indicator. The PUCCH resource is determined based on an index of the first control channel element. The PUCCH resource is determined based on the control resource set. An uplink control information is transmitted via the PUCCH resource in response to the determination of the PUCCH resource.

The configuration parameters indicate a first reference signal set for a first type of beam switching. The configuration parameters indicate a second reference signal set for a second type of beam switching. A beam switching type indication is transmitted. The beam switching type indication indicates one of the first type of beam switching or the second type of beam switching. A command confirming the beam switching type indication is received. One of the first reference signal set and the second reference signal set is selected as a selected reference signal set based on the command A spatial domain transmission filter is determined based on at least one reference signal of the selected reference signal set. An uplink transport block is transmitted based on the spatial domain transmission filter.

摘要： In an embodiment a wireless device receives configuration parameters, of a cell, indicating: a first reference signal (RS) of a first transmission reception point (TRP) of the cell; a second RS of a second TRP of the cell; random access channel (RACH) resources of a RACH of the cell; and a power offset value. The wireless device measures a first received power value of the first RS and measures a second received power value of the second RS. The wireless device selects, based on the measuring and the power offset value, an RS from the first RS and the second RS. Then, the wireless device transmits a preamble, associated with the selected RS, via the RACH resources.

摘要： Described are embodiments for uplink transmission using multiple panels. In an embodiment, a wireless device receives configuration parameters indicating a transmission configuration indication (TCI) state index is associated with: a first TCI state, of a first antenna panel, for uplink transmissions; and a second TCI state, of a second antenna panel, for uplink transmissions. The wireless device receives a command indicating the TCI state index and determines, based on the configuration parameters, the first TCI state and the second TCI state associated with the TCI state index indicated in the command. The wireless device transmits, via the first antenna panel, one or more first transport blocks based on the first TCI state. The wireless transmits, via the second antenna panel, one or more second transport blocks based on the second TCI state.
