摘要： A wireless device receives one or more messages comprising configuration parameters. The configuration parameters indicate pathloss reference signals (RSs) for PUSCH pathloss estimation for transmissions via first and second panels. A medium access control control element (MAC CE) is received. The MAC CE indicates first pathloss RSs of the plurality of pathloss RSs for the first panel. The MAC CE indicates second pathloss RSs of the plurality of pathloss RSs for the second panel. A downlink control information (DCI) is received. The DCI indicates a first pathloss RS. The DCI indicates a second pathloss RS. The wireless device transmits, via the first panel, a first uplink transport block with a first uplink transmission power determined based on the first pathloss RS. The wireless device transmits, via the second panel, a second uplink transport block with a second uplink transmission power determined based on the second pathloss RS.

摘要： A base station transmits to a wireless device, a first request to measure synchronization signal(s) of a first cell. The base station receives from the wireless device, measurement report(s) of at least one synchronization signal of the synchronization signal(s). The base station transmits to the wireless device, a second request to measure CSI-RS(s) of the first cell. The base station receives from the wireless device, second measurement report(s) of the CSI-RS(s). The second measurement report(s) are generated in response to the second request. The base station selects first CSI-RS(s) of the CSI-RS(s) based on the second measurement report(s). The base station transmits a downlink control information to the wireless device via one or more control channels. The downlink control information initiates a random access procedure of the first cell. The downlink control information comprises an indication of the first CSI-RS(s).

摘要： A wireless device monitors a downlink control channel of a transmission reception point (TRP) on an active bandwidth part (BWP) of a cell, where the TRP is in an active state. First channel state information reports of the TRP for the active BWP are transmitted. The TRP transitions from the active state into a dormant state in response to a first time period of inactivity on the TRP. The monitoring is stopped. Second channel state information reports of the TRP for the active BWP are transmitted when the TRP is in the dormant state.

摘要： A wireless device transmits a first scheduling request (SR) based on a buffer status reporting procedure. A second SR is triggered in response to initiating a beam failure recovery. The second SR is transmitted via an uplink control channel resource configured for the second SR. A first downlink control information is received via a downlink control channel, as a response to the second SR. Based on receiving the first downlink control information: the first SR is keep pending, and the second SR is cancelled for the beam failure recovery.

摘要： A wireless device receives one or more messages comprising: first configuration parameters of a plurality of cells comprising a primary cell and a secondary cell; and bandwidth part configuration parameters comprising a value for a bandwidth part inactivity timer. A downlink control information is received on an active bandwidth part of the primary cell. The downlink control information indicates a resource assignment. In response to the receiving the downlink control information, a determination is made that no random access procedure is ongoing on the secondary cell. The bandwidth part inactivity timer of the active bandwidth part of the primary cell is started in response to the determining. In response to an expiry of the bandwidth part inactivity timer, a switch is made from the active bandwidth part to a default bandwidth part.

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.

摘要： A wireless device receives message(s) comprising configuration parameter(s) indicating reference signal(s) of a cell. The configuration parameter(s) may indicate one or more preambles for a beam failure recovery procedure. The configuration parameter(s) may indicate a time alignment timer of a timing advance group comprising the cell. The time alignment timer may start in response to receiving a timing advance command for the timing advance group. The beam failure recovery procedure may be initiated in response to detecting a beam failure of the cell. The beam failure of the cell may be detected based on the reference signal(s) of the cell. A preamble of the one or more preambles may be transmitted for the beam failure recovery procedure. The beam failure recovery procedure may be aborted in response to an expiry of the time alignment timer during the beam failure recovery procedure.

摘要： A base station central unit transmits to a first base station distributed unit, a first message requesting a first context setup for a wireless device. The base station central unit transmits to a second base station distributed unit, a second message requesting second context setup to add the second base station distributed unit for the wireless device. The second message comprises a second power value for uplink transmission of the wireless device to the second base station distributed unit. The base station central unit receives a response message indicating the second context setup for the wireless device. The base station central unit transmits to the first base station distributed unit, a third message requesting context modification for the wireless device. The third message comprises a first power value, determined based on the second power value, for uplink transmission of the wireless device to the first base station distributed unit.

摘要： A wireless device receives a DCI from a base station. The DCI comprises a power control command of an uplink shared channel, a CSI request field, a hybrid automatic repeat request process number, and a redundancy version. Validation of the DCI for an activation of a semi-persistent CSI reporting is performed based on: a radio network temporary identifier of the semi-persistent CSI reporting, the hybrid automatic repeat request process number being set to a first value, and the redundancy version being set to a second value. The semi-persistent CSI reporting indicated by the CSI request field is activated in response to the validation being achieved. A semi-persistent CSI report is transmitted, based on the activated semi-persistent CSI reporting, via the uplink shared channel with a transmission power determined based on the power control command.

摘要： A wireless device may receive at least one message comprising: first configuration parameters of a first bandwidth part, and second configuration parameters of a second bandwidth part. The second configuration parameters may comprise a scheduling request configuration indicating scheduling request resources for a logical channel. A scheduling request may be triggered in response to data becoming available for the logical channel. A random access process may be started in response to a valid scheduling request resource for the logical channel not being available on the first bandwidth part. A downlink control information may be received. The downlink control information may indicate switching from the first bandwidth part to the second bandwidth part. In response to the scheduling request resources being available on the second bandwidth part: the random access process may be cancelled, and a scheduling request signal may be transmitted via the scheduling request resources.
