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 from a second base station, a RRC message comprising access information, for a handover to a first cell of a first base station, indicating that a first timing advance of a first beam of the first cell is a timing advance of a first timing advance group of a secondary cell group and that a second timing advance of a second beam of the first cell is a timing advance of a second timing advance group of the secondary cell group. The wireless device selects, as a selected beam, one of the first beam and the second beam. The wireless device transmits transport blocks, via the selected beam of the first cell, using one of: the first timing advance in response to the selected beam being the first beam; and the second timing advance in response to the selected beam being the second beam.

摘要： In some embodiments, a wireless device receives a plurality of downlink control information (DCIs) via a plurality of resource block (RB) sets of a bandwidth part of a cell. The plurality of DCIs indicate downlink radio resources. The wireless device receives a transport block via the downlink radio resources. Based on RB set indexes of the plurality of RB sets, the wireless device determines a DCI from the plurality of DCIs. Then, the wireless device transmits feedback information, for the transport block, via an uplink control channel resource determined based on the DCI.

摘要： Described are embodiments for selecting a preamble for a random access procedure. In an embodiment, a wireless device receives one or more configuration parameters of physical random access channel (PRACH) occasions for the random access procedure. One or more PRACH occasions of the PRACH occasions correspond to a respective RS of a plurality of RSs. The wireless device determines a RS, from the plurality of RSs, based on a reference signal received power (RSRP) value of the RS, and a transmission power reduction value associated with the RS. The wireless device determines a PRACH occasion, associated with the RS, from the PRACH occasions. Then, the wireless device transmits, via the PRACH occasion, a preamble for the random access procedure.

摘要： A wireless device receives configuration parameters indicating a maximum permissible exposure (MPE) threshold. First uplink signals are transmitted via a first antenna panel. A downlink control information (DCI) indicating switching from the first antenna panel to a second antenna panel is received. An MPE event is detected based on the MPE threshold and a power value associated with the second antenna panel. Based on the detecting the MPE event: the switching indication is ignored by not switching to the second antenna panel; and second uplink signals are transmitted via the first antenna panel.

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 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.
