    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 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 receives one or more messages. The one or more messages comprise discontinuous reception configuration parameters comprising a value for a discontinuous reception inactivity timer. A first downlink control information is received that indicates a channel state information request; and no uplink packet transmission. The discontinuous reception inactivity timer is started in response to the first downlink control information indicating the channel state information request and no uplink packet transmission. A second downlink control information is received while the discontinuous reception inactivity timer is running. One or more transport blocks is transmitted based on the second downlink control information.

    摘要: A wireless device receives, from a first base station, message(s) comprising configuration parameter(s) of a second base station comprising a cell. The configuration parameter(s) indicate a cell radio identifier, a plurality of random access preambles of the cell, and random access channel occasion(s) of the cell. The wireless device transmits, to the second base station via the random access channel occasion(s), random access preamble(s) of the plurality of random access preambles using a plurality of transmit beams. The wireless device receives random access response(s) identified by the cell radio identifier. The random access response(s) comprise a first preamble identifier corresponding to a first random access preamble of the random access preamble(s). The wireless device determines a first transmit beam of the plurality of transmit beams used to transmit the first random access preamble. The wireless device transmits, to the second base station, data using the first transmit beam.

    摘要: A wireless device receives a timer value of a DRX on duration timer for a DRX operation; radio resources of a reference signals for a transmission of a layer 1 reference signal received power report; and a report indicator indicating the transmission of the layer 1 reference signal received power report is limited to a time period when the DRX on duration timer is running. The layer 1 reference signal received power report is transmitted at a first time based on the DRX on duration timer running at a predefined time period before the first time. The layer 1 reference signal received power report includes a layer 1 reference signal received power value and a reference signal resource index associated with one of the reference signal(s). Based on the report indicator, transmitting of the layer 1 reference signal received power report at a second time is skipped in response to the DRX on duration timer not running at the predefined time period before the second time.
