摘要： A wireless device receives message(s) comprising: a first value for a downlink hybrid automatic repeat request (HARQ) round-trip-time (RTT) timer; and a second value for a downlink discontinuous reception (DRX) retransmission timer. A downlink control information indicating downlink transmission of a transport block is received. The downlink HARQ RTT timer is started with the first value in response to receiving the downlink control information. The first value indicates a first number of symbols. The downlink DRX retransmission timer is started with the second value in response to the downlink HARQ RTT timer expiring and the transport block not being successfully decoded. The second value indicates a second number of slot lengths. A downlink control channel is monitored while the downlink DRX retransmission timer is running.

摘要： A wireless device may detect a beam failure on at least one beam. The at least one beam may be of a first cell. A beam failure recovery procedure may be started in response to the beam failure. The beam failure recovery procedure may comprise transmitting a recovery request for a first beam. A beam failure recovery timer for the beam failure recovery procedure may be started. The wireless device may determine a connection failure based on expiration of the beam failure recovery timer. The wireless device may transmit a radio link failure report to a first base station based on the connection failure. The radio link failure report may comprise an index of the first beam.

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 activates a first downlink bandwidth part (BWP) of a cell and a first uplink BWP of the cell. An active downlink BWP, identified with a second downlink BWP index, is switched from the first downlink BWP to a second downlink BWP. It is determined that the second downlink BWP is configured with one or more beam failure recovery (BFR) parameters. An active uplink BWP, identified with a second uplink BWP index that is the same as the second downlink BWP index, is switched, based on the determining, from the first uplink BWP to a second uplink BWP. The active downlink BWP is switched from the second downlink BWP to a third downlink BWP. Based on a determination that the third downlink BWP is not configured with one or more BFR parameters, the second uplink BWP is kept as the active uplink BWP.

摘要： A wireless device receives message(s) indicating: a first resource for a first uplink control channel and a second resource for a second uplink control channel of a cell. The first resource and the second resource overlap in symbol duration(s). A first power level is determined for transmission of first uplink control information via the first resource. A second power level is determined for transmission of second uplink control information via the second resource. The first power level is scaled based on a first scaling factor. The first scaling factor is determined based on a first priority of the first uplink control channel. The second power level is scaled based on a second scaling factor. The second scaling factor is determined based on a second priority of the second uplink control channel. A sum of the power levels is larger than an allowed transmission power.

摘要： A wireless device may receive configuration parameters for configured uplink transmissions via a plurality of resources. A first uplink transmission may be associated with a first resource in the plurality of resources and may be associated with a first HARQ process number. The wireless device may cancel a trigger for transmitting a buffer status report and create a first packet comprising the buffer status report for transmission via the first resource. The wireless device may receive, before a scheduled transmission of the first packet, a downlink control information for transmission of a second packet. The second packet may be associated with the first HARQ process number. In response to the downlink control information, the wireless device may drop the scheduled transmission of the first packet via the first resource and trigger the trigger for transmitting the buffer status report in response to receiving the downlink control information.

摘要： Message(s) are received that comprise configuration parameters of a cell. The cell comprises a first downlink BWP, a second downlink BWP and uplink BWP(s). The configuration parameters comprise: first parameters of first uplink control channel resource on the at least one uplink BWP for first CSI reports of the first downlink BWP; and second parameters of second uplink control channel resource on the uplink BWP(s) for second CSI reports of the second downlink BWP. The first CSI reports of the first downlink BWP are transmitted via the first uplink control channel resource on an uplink BWP of the uplink BWP(s). An active BWP is switched from the first downlink BWP to the second downlink BWP. The second CSI reports of the second downlink BWP are transmitted, after the switching, via the second uplink control channel resource on the uplink BWP of the uplink BWP(s).
