Abstract: A wireless device may change from communicating with a first node to communicating with a second node, for example, based on a switch or a handover. A wireless device that receives an indication for a switch (e.g., to a satellite or wireless communication device) and an indication for a handover may determine which to perform based on a time indicated for the switch. For example, the handover may be initiated after receiving an indication to perform the switch if the handover is initiated before the time for the switch.

Abstract: A base station transmits, to a wireless device, at least one radio resource control (RRC) message comprising configuration parameters of an unlicensed cell. The base station transmits a first physical downlink control channel (PDCCH) to initiate a random access procedure on the unlicensed cell. In response to a listen-before-talk (LBT) procedure indicating a clear channel for uplink transmission of a first preamble of the random access procedure, the base station receives the first preamble via a random access channel (RACH) of the unlicensed cell and transmits a second PDCCH for a random access response (RAR). In response to the LBT procedure indicating an LBT failure, the base station receives a second preamble based on a random access resource selection procedure and does not transmit the second PDCCH for the RAR.
