摘要： A wireless device may receive one or more messages. The one or more messages may comprise configuration parameters of a first uplink control channel and a second uplink control channel. Downlink control information may be received. The downlink control information may indicate a downlink transmission of a transport block via a downlink channel. One of the first uplink control channel or the second uplink control channel may be selected as a selected uplink control channel based on one or more parameters of the downlink control information. A hybrid automatic repeat request (HARD) feedback for the transport block may be transmitted via the selected uplink control channel.

摘要： A base station distributed unit may transmit a timing advance command for a timing advance group to a wireless device. The base station distributed unit may start a time alignment timer for the timing advance group of the wireless device in response to the transmission of the timing advance command. The base station distributed unit may determine expiration of the time alignment timer. The base station distributed unit may transmit a first message to a base station central unit. The first message may indicate the expiration of the time alignment timer for the timing advance group of the wireless device.

摘要： A wireless device receives message(s) comprising configuration parameter(s) of a first cell and a second cell. The configuration parameter(s) indicate a plurality of bandwidth parts (BWPs) of the first cell. A first uplink BWP of the plurality of BWPs is activated as an active uplink BWP. A beam failure recovery procedure for the second cell is initiated based on detecting a beam failure. A determination that the first uplink BWP is not configured with one or more beam failure recovery resources for the second cell is made. The active uplink BWP of the first cell is switched, based on the determination, from the first uplink BWP to a second uplink BWP, of the plurality of BWPs, configured with the one or more beam failure recovery resources for the second cell. An uplink signal indicating the beam failure is transmitted via the second uplink BWP.

摘要： The wireless device receives one or more radio resource control messages comprising configuration parameters of a cell. The configuration parameters indicate: a first set of transmission time intervals configured for a first control resource set (coreset) group of the cell; a first transmission configuration indicator (TCI) state of the first coreset group; a second set of transmission time intervals configured for a second coreset group of the cell; and a second TCI state of a second coreset group. A first downlink control information (DCI) comprising an assignment of a resource of the cell is received. A TCI state for the resource is selected, based on which of the first set of transmission time intervals or the second set of transmission time intervals overlaps in time with the resource, one of: the first TCI state; or the second TCI state. Based on the TCI state, data is received via the resource.

摘要： A base station central unit transmits a first message to a base station distributed unit. The first message comprises first configuration parameters of a wireless device. The base station central unit receives a second message from the base station distributed unit indicating acknowledgement of the first message. The second message comprises second configuration parameters based on the first configuration parameters. The base station central unit transmits to the wireless device via the base station distributed unit, a third message comprising the second configuration parameters. The base station central unit receives from the wireless device via the base station distributed unit, a fourth message confirming at least one of the second configuration parameters. The base station central unit transmits to the base station distributed unit, a fifth message indicating that the wireless device successfully performed a reconfiguration procedure based on the second configuration parameters.

摘要： A wireless device receives message(s) from a base station comprising configuration parameters of a first uplink bandwidth part of a cell. The configuration parameters comprise: a bandwidth part configuration parameter of the first uplink bandwidth part, and random access channel parameters of a random access channel resource. A preamble is transmitted via the random access channel resource on the first uplink bandwidth part. A random access radio network temporary identifier (RA-RNTI) is determined based on the bandwidth part configuration parameter and one or more of the random access channel parameters. A downlink control channel is monitored for a downlink control information addressed to the RA-RNTI in response to the determining. The downlink control information indicates a downlink radio resource of a random access response is received. The random access response is received via the downlink radio resource in response to the downlink control information.

摘要： A wireless device receives a radio resource control message from a first base station. The radio resource control message comprises bandwidth part (BWP) configuration parameters of a plurality of BWPs of a first cell. The BWP configuration parameters comprise: an index of a BWP of the plurality of BWPs; and a field indicating a bandwidth of the BWP. The wireless device receives transport blocks via one or more of the plurality of BWPs based on the BWP configuration parameters. The wireless device detects, during a time that the BWP is active, a connection failure with the first base station. The wireless device transmits a radio link failure report indicating the connection failure. The radio link failure report comprises: a cell identifier of the first cell; and the index of the BWP.

摘要： A wireless device receives configuration parameters of one or more configured grants of an unlicensed cell. The wireless device receives a downlink control information indicating an uplink grant for a first TB corresponding to a first HARQ process. The wireless device stores, based on a first LBT procedure indicating a busy channel, the first TB in a first HARQ buffer associated with the first HARQ process. The first LBT is for a scheduled transmission of the first TB. The wireless device flushes, based on a second LBT procedure indicating a busy channel, a second HARQ buffer associated with a second HARQ process. The second LBT procedure is for a scheduled transmission of a second TB via a first configured grant of the one or more configured grants.

摘要： A wireless device receives configuration parameters comprising a monitoring periodicity and a first parameter indicating symbol(s). A downlink control channel is monitored for a DCI indicating slot formats of bandwidth part(s) of a cell during monitoring symbol(s) determined based on the monitoring periodicity and the first parameter. The DCI may be received during the monitoring symbol(s). The DCI may comprise first fields identifying the bandwidth part(s) of the cell. The DCI may comprise second field(s) indicating slot formats of the bandwidth part(s). A first slot format of an active bandwidth part of the bandwidth part(s) may be determined based on the first field(s) and the second field(s). The wireless device may transmit transport block(s) in uplink symbol(s) of the active bandwidth part determined based on the first slot format.

摘要： A wireless device receives from a base station, one or more messages comprising configuration parameters of a layer 1 reference signal received power reporting for a secondary cell. The configuration parameters indicate resource configurations of a plurality of reference signals on the secondary cell. A medium access control control element indicating activation of the secondary cell is received. In response to the medium access control control element, a layer 1 reference signal received power report for the layer 1 reference signal received power reporting for the secondary cell is transmitted. The layer 1 reference signal received power report comprises: first fields indicating at least one reference signal of the plurality of reference signals; and second fields indicating at least a layer 1 reference signal received power value of the at least one reference signals.
