Apparatus and methods for group wireless transmit/receive unit (WTRU) handover
Abstract
Apparatus and methods of handing over a wireless transmit/receive unit (WTRU) that belongs to a group of WTRUs from an originating base station to a target base station are described. A method includes the WTRU obtaining information regarding a group to which the WTRU has been assigned and the WTRU receiving at least one of handover reconfiguration information that is common to the group and handover reconfiguration information that is specific to the WTRU. On a condition that the WTRU receives the handover reconfiguration information that is specific to the WTRU, the WTRU initiates a synchronization procedure with the target base station based at least on the received handover reconfiguration information.
