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 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.

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 configuration parameters of physical uplink control channel (PUCCH) resources of a cell. The PUCCH resources are grouped into a plurality of PUCCH resource groups. A downlink control information (DCI), indicating an uplink grant, is received via a control resource set. A PUCCH resource group is selected, based on the control resource set, from the plurality of PUCCH resource groups. A spatial relation information corresponding to a first PUCCH resource of the selected PUCCH resource group is determined. An uplink transport block is transmitted via the uplink grant based on the spatial relation information.

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 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 initiates a beam failure recovery procedure in response to detecting a number of beam failure instances based on a first plurality of reference signals. A beam failure recovery timer is started with a timer value in response to the detecting. A physical layer of the wireless device assesses, during the beam failure recovery timer running, a first radio link quality of a second plurality of reference signals against a threshold. The beam failure recovery procedure is completed in response to the beam failure recovery timer expiring and the first radio link quality being below the threshold. Information indicating that the beam failure recovery procedure failed due to the first radio link quality being below the threshold is reported to a radio resource control layer of the wireless device.

摘要： A wireless device receives a first downlink control information indicating activation of a semi-persistent channel state information reporting. A first medium access control (MAC) control element (CE) is transmitted confirming the first downlink control information. The first MAC CE is identified by a first MAC subheader with a first logical channel identifier for the semi-persistent channel state information reporting. A second downlink control information indicating activation of a configured uplink grant is received. A second MAC CE confirming the second downlink control information is transmitted. The second MAC CE is identified by a second MAC subheader with a second logical channel identifier for the configured uplink grant.
