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.

Claim
A first wireless transmit/receive unit (WTRU) comprising:
a transceiver configured to receive, from a second WTRU, a group identifier associated with a WTRU group in proximity to the second WTRU, wherein the first WTRU receives, from the second WTRU, information that the second WTRU received from a wireless network; the transceiver and a processor configured to measure a signal strength of the second WTRU for use in determining whether the first WTRU is to remain in the group; and the transceiver and the processor configured to select another group based on a determination that the first WTRU is not to remain in the group.
2. The first WTRU of claim 1, wherein:
the transceiver is further configured to receive a message with the group identifier, wherein the received message is associated with the group.
3. The first WTRU of claim 1, wherein:
the transceiver is further configured to send a measurement report of the measured signal strength of the second WTRU.
4. The first WTRU of claim 1, wherein:
the transceiver is further configured to send an indication that the first WTRU is not to remain in the group.
5. The first WTRU of claim 1, wherein the determination that the first WTRU is not to remain in the group is based on the measured signal strength of the second WTRU being below a threshold.
6. The first WTRU of claim 1, wherein the measured signal strength of the second WTRU is an individual measurement.
7. The first WTRU of claim 1, wherein the measured signal strength of the second WTRU is an averaged or filtered measurement.
8. A method performed by a first wireless transmit/receive unit (WTRU) the method comprising:
receiving, from a second WTRU, a group identifier associated with a WTRU group in proximity to the second WTRU, wherein the first WTRU receives, from the second WTRU, information that the second WTRU received from a wireless network; measuring a signal strength of the second WTRU for use in determining whether the first WTRU is to remain in the group; and selecting another group based on a determination that the first WTRU is not to remain in the group.
9. The method of claim 8, further comprising:
receiving a message with the group identifier, wherein the received message is associated with the group.
10. The method of claim 8, further comprising:
sending a measurement report of the measured signal strength of the second WTRU.
11. The method of claim 8, further comprising:
sending an indication that the first WTRU is not to remain in the group.
12. The method of claim 8, wherein the determination that the first WTRU is not to remain in the group is based on the measured signal strength of the second WTRU being below a threshold.
13. The method of claim 8, wherein the measured signal strength of the second WTRU is an individual measurement.
14. The method of claim 8, wherein the measured signal strength of the second WTRU is an averaged or filtered measurement.
