Abstract: A method may include sending, by a base station to a wireless device, a radio resource control (RRC) message indicating a handover to a cell. The RRC message can indicate a first timing advance of a first beam of the cell and a second timing advance of a second beam of the cell. The first timing advance and the second timing advance can be provided for beam selection by the wireless device for transmission, via a selected beam of the first beam or the second beam, transport blocks using one of the first timing advance or the second timing advance corresponding to the selected beam.

Abstract: A wireless device receives a radio resource control (RRC) release message indicating one or more configured grants for small data transmission (SDT) in an RRC inactive state and one or more synchronization signal and physical broadcast channel blocks (SSBs) used for the SDT. The wireless device receives downlink control information based on a demodulation reference signal (DM-RS) antenna port for downlink control channel reception being quasi co-located with an SSB, of the one or more SSBs, selected during a most recent SDT, wherein the downlink control information indicates uplink radio resources. The wireless device transmits a transport block via the uplink radio resources.

Abstract: A wireless device receives, from a base station, one or more messages indicating: a control resource set (coreset) of a bandwidth part of a cell; and a first reference signal (RS) associated with the coreset. A downlink control channel in the coreset is monitored based on the first RS. A control command indicating a group of one or more second RSs is received. The wireless device determines that the group of the one or more second RSs does not include the first RS. In response to the determining, the wireless device stops monitoring the downlink control channel in the coreset.

Abstract: A base station may transmit, to a wireless device, first downlink control information (DCI) via a physical downlink control channel (PDCCH) of an active bandwidth part (BWP), of the wireless device, during a discontinuous reception (DRX) active time. The base station may switch to a first downlink BWP as the active BWP during the DRX active time. The base station may start, in response to the switching, a BWP inactivity timer of the first downlink BWP. The base station may transmit a second DCI via a PDCCH of the first downlink BWP. The base station may receive a packet via a transmission interval of periodic resources indicated by a configured grant. The base station may restart the BWP inactivity timer at a time based on the transmission interval. The base station may switch, in response to an expiration of the BWP inactivity timer, to a second downlink BWP as the active BWP during the DRX active time. The base station may transmit a third DCI via a PDCCH of the second downlink BWP.
