Abstract: A wireless device (18) is configured for use in a wireless communication network (10), e.g., a non-terrestrial network. The wireless device (18) is configured to receive, from a network node (20) in the wireless communication network (10), signaling (22) that indicates reconfiguration of a beam (16) serving the wireless device (18). The wireless device (18) in some embodiments is also configured to, responsive to receiving the signaling (22), reacquire time and/or frequency synchronization for the beam (16), e.g., to account for the indicated reconfiguration of the beam (16).

Abstract: A communication device in a communication network can be configured to provide uplink communication using a first uplink carrier and a second uplink carrier. The communication device can provide a parameter relating to a time duration (Tswitch) required to switch an uplink transmit chain from the first carrier to the second carrier. The communication device can further transmit the parameter relating to the time duration (Tswitch) required to switch the uplink transmit chain from the first carrier to the second carrier to the communication network.
