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： 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 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 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 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.

摘要： A wireless device receives from a base station, message(s) comprising configuration parameters of a cell. The configuration parameters may comprise BWP parameters of a first BWP and a second BWP, and a timer value associated with a BWP inactivity timer. A first DCI may be received at a first slot. The first DCI may indicate switching to the second BWP as an active BWP. In response to the first DCI, the first BWP may switch to the second BWP as the active BWP. In response to the first DCI, the BWP inactivity timer may be started at a second slot based on the timer value. The second slot may occur after the first slot by an amount of time determined based on a time offset value. A default BWP may be switched to in response to an expiry of the BWP inactivity timer.

摘要： A wireless device receives configuration parameters of one or more configured grants of an unlicensed cell. The wireless device transmits, based on a configured grant of the one or more configured grants, one or more code block groups of a transport block and a code block group transmission information. The code block group transmission information indicates a presence of the one or more code block groups for the transport block. The wireless device receives a downlink control information comprising a first field and a second field. The first field indicates that the base station received the code block group transmission information. The second field indicates hybrid automatic repeat request feedbacks for the one or more code block groups.

摘要： A wireless device receives one or more downlink control information. The one or more downlink control information indicate negative acknowledgements. The negative acknowledgements are for one or more first code block groups of a first transport block corresponding to a first hybrid automatic repeat request (HARQ) process and one or more second code block groups of a second transport block corresponding to a second HARQ process. The wireless device determines that a size of a first configured grant is sufficient to retransmit the one or more first code block groups and the one or more second code block groups. Based on the determining, the wireless device retransmits, via radio resources of the first configured grant, the one or more first code block groups and the one or more second code block groups.
