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 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 message comprising configuration parameters of a plurality of cells. An activation command indicating activation of a plurality of secondary cells (SCells) of the plurality of cells is received. A first downlink control information (DCI), comprising a power saving indication bitmap, is received. Each bit of the power saving indication bitmap indicates whether to monitor a downlink control channel on a corresponding activated SCell of the plurality of SCells. The wireless device starts monitoring a downlink control channel of an activated SCell of the activated SCells, in response to a bit, of the power saving indication bitmap, corresponding to the activated SCell, indicating monitoring the downlink control channel. A second DCI is received via the downlink control channel.

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 of a first uplink carrier and a second uplink carrier of an unlicensed cell. A switch is made from the first uplink carrier to the second uplink carrier. A first contention window size determining based on the switch. Based on the first contention window size, a listen before talk procedure is performed for transmission of a transport block in one or more subbands of the second uplink carrier. A transport block is transmitted based on the listen before talk procedure indicating a clear channel.

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 radio access network receives from an access and mobility management function, a first message comprising an Ethernet packet filter set for a wireless device. The Ethernet packet filter set comprises: source medium access control address; and a destination medium access control address. The radio access network determines, based on the Ethernet packet filter set, Ethernet header configuration parameters for the wireless device, wherein the Ethernet header configuration parameters comprise: a header compression index indicating the source medium access control address and the destination medium access control address; and Ethernet header profile configuration information element(s) comprising a profile identifier. The radio access network sends to the wireless device, second message(s) comprising the Ethernet header configuration parameters. The radio access network sends to the wireless device, Ethernet packet(s) comprising packet header(s) compressed based on the header compression index and the profile identifier.

摘要： A wireless device sends, to an access and mobility management function (AMF) via an access network, a first registration request message comprising a first geographical coordinate of a first geographical location. The wireless device receives a registration accept message comprising a radius value from the AMF. The wireless device moves to a second geographical location. The wireless device determines that a distance between the first geographical coordinate and a second geographical coordinate of the second geographical location is larger than the radius value. In response to the determination, the wireless device sends a second registration request message comprising the second geographical coordinate.

摘要： A wireless device receives one or more radio resource control messages comprising configuration parameters for a cell. The configuration parameters indicate a plurality of coreset groups corresponding to a plurality of transmission and reception points (TRPs). Each coreset in the plurality of coreset groups is associated with a transmission configuration indicator (TCI) state. A coreset group of the plurality of coreset groups is selected for a radio link monitoring of the cell. The selection is in response to the coreset group comprising a coreset with a pre-defined index value. One or more reference signals are monitored based on one or more TCI states of one or more coresets of the coreset group.
