Document Type and Number:
WIPO Patent Application WO/2022/236631
Kind Code:
A1
Abstract:
Disclosed are methods and apparatus for user equipment to network relay handover. An embodiment of the subject application provides a method performed by a relay node. The method includes receiving a radio resource control reconfiguration message including a reconfiguration with synchronization from a serving cell, and transmitting a handover associated indication to a remote user equipment via sidelink communication in response to reception of the RRC reconfiguration message including the reconfiguration with synchronization. In addition, the relay node may transmit the indication associated with successful handover to the remote UE via sidelink communication after successful handover.
