摘要： A wireless device receives one or more messages comprising spatial relation configuration parameters of a physical uplink control channel. The configuration parameters indicate a plurality of reference signal (RS) sets. An RS set of the plurality of RS sets comprises one or more RSs. A medium access control control element, activating the RS set of the plurality of RS sets, is received. A downlink control information, indicating an RS of the RS set, is received. A spatial domain transmission filter, for the physical uplink control channel, is determined based on based on the RS. Uplink control information is transmitted, via the physical uplink control channel, based on the spatial domain transmission filter.

摘要： A wireless device receives one or more radio resource control messages from a base station. The one or more radio resource control messages comprising configuration parameters of a cell for beam failure recovery. The configuration parameters indicate: a serving beam set, a plurality of candidate beam sets, and a monitoring priority of the plurality of candidate beam sets. A beam failure instance of the serving beam set is detected. In response to the detection, a first candidate beam set of the plurality of candidate beam sets is determined based on the monitoring priority. A candidate beam is selected from the first candidate beam set. A preamble associated with the candidate beam for the beam failure recovery is transmitted.

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.

摘要： A wireless device receives one or more configuration parameters for uplink bandwidth parts (BWPs) of a cell. A first preamble, for a random-access procedure, is transmitted via a first uplink BWP of the uplink BWPs. A random-access response comprising a backoff indicator is received. A backoff window associated with the backoff indicator is started. A second uplink BWP of the uplink BWPs, that is different from the first uplink BWP, is selected for transmission of a second preamble during the backoff window. The wireless device transmits, via the second uplink BWP and based on the selecting, the second preamble for the random-access procedure.

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 wireless device receives one or more first radio resource control (RRC) messages. The first RRC messages comprise one or more configuration parameters of a first cell and a second cell. A second RRC message is received. The second RRC message indicates a first change of a first active bandwidth part (BWP) of the first cell. Processing of the second RRC message is completed. A determination is made that the completing occurs during a time duration of a second change of a second active BWP of the second cell. Based on the determining, the first change of the first active BWP is delayed until the second change of the second active BWP is completed.

摘要： A wireless device receives first configuration parameters of a first bandwidth part and a second bandwidth part of a licensed cell; and second configuration parameters of a third bandwidth part and a fourth bandwidth part of an unlicensed cell. A first downlink control information indicating switching from the first bandwidth part to the second bandwidth part as an active bandwidth part is received. A second downlink control information indicating switching from the third bandwidth part to the fourth bandwidth part as an active bandwidth part is received. Based on the receiving the first downlink control information: the wireless device switches from the first bandwidth part to the second bandwidth part; and does not transmit a confirmation. Based on the receiving the second downlink control information, the wireless device switches from the third bandwidth part to the fourth bandwidth part; and transmits a confirmation.

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.
