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 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.

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 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： A wireless device receives one or more messages. The one or more messages indicate: a plurality of repetition values of a physical sidelink shared channel (PSSCH); and a repetition threshold for the PSSCH. A sidelink control information is received. The sidelink control information schedules a transport block. The sidelink control information indicates a first repetition value of the plurality of repetition values. The transport block is received via the PSSCH. A determination is made, based on the first repetition value and the repetition threshold, to transmit an acknowledgment for the transport block. The acknowledgment for the transport block is transmitted.

摘要： A first wireless device receives, from a base station, configuration parameters of a resource pool of a sidelink. The configuration parameters indicate a primary zone configuration, a secondary zone configuration, and a first primary zone identifier of a first primary zone. a second primary zone identifier of a second primary zone in which the first wireless device is positioned, is determined based on a geographic location of the first wireless device using the primary zone configuration. A secondary zone identifier of a secondary zone in which the first wireless device is positioned, is determined based on the geographic location using the secondary zone configuration. The first wireless device transmits control information indicating the secondary zone identifier to second wireless device(s). The control information is transmitted via the resource pool, in response to the second primary zone identifier being the same as the first primary zone identifier.

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.

摘要： A wireless device receives configuration parameters comprising first parameters of downlink RSs and second parameter indicating that a default beam is used for uplink transmission. A DCI indicating a first uplink transmission via a PUSCH resource is received. A spatial relation information, for the first uplink transmission, is determined to be associated with one of the downlink reference signals in response to the second parameter indicating that the default beam is used. A transport block is transmitted via the PUSCH resource according to the spatial relation information.
