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 long term evolution (LTE) wireless transmit/receive unit (WTRU) comprising:
a transceiver configured to receive from a second LTE WTRU a group identifier associated with a group of WTRUs in proximity to the second LTE WTRU;
the transceiver further configured to receive configuration information indicating subframes in which to monitor at least one LTE physical channel to determine whether messages have the group identifier;
the transceiver further configured to monitor the at least one LTE physical channel for messages with the group identifier in the indicated subframes; and
the transceiver further configured to receive a message with the group identifier over the at least one LTE physical channel, wherein the received message is associated with the group, and wherein the at least one LTE physical channel is not an LTE physical downlink shared channel (PDSCH) and is not an LTE physical downlink control channel (PDCCH).
2. The first LTE WTRU of claim 1, wherein the configuration information is received from an evolved Node B (eNB).
3. A first long term evolution (LTE) wireless transmit/receive unit (WTRU) comprising:
a transceiver configured to receive configuration information indicating subframes for transmission on at least one LTE physical channel, wherein the at least one LTE physical channel is not an LTE physical downlink shared channel (PDSCH) and is not an LTE physical downlink control channel (PDCCH);
the transceiver further configured to communicate using the at least one LTE physical channel, wherein messages sent over the at least one LTE physical channel intended for a group have a group identifier associated with the group; and
the transceiver further configured to transmit messages intended for the group with the group identifier on the at least one LTE physical channel in the indicated subframes.
4. The first LTE WTRU of claim 3, wherein the configuration information is received from an evolved Node B (eNB).
5. A method performed by a first long term evolution (LTE) wireless transmit/receive unit (WTRU), the method comprising:

receiving configuration information indicating subframes in which to monitor at least one LTE physical channel to determine whether messages have the group identifier;
monitoring the at least one LTE physical channel for messages with the group identifier in the indicated subframes; and
receiving a message with the group identifier over the at least one LTE physical channel, wherein the received message is associated with the group, and wherein the at least one LTE physical channel is not an LTE physical downlink shared channel (PDSCH) and is not an LTE physical downlink control channel (PDCCH).
6. The method of claim 5, wherein the configuration information is received from an evolved Node B (eNB).
7. A method performed by a first long term evolution (LTE) wireless transmit/receive unit (WTRU), the method comprising:
receiving configuration information indicating subframes for transmission on at least one LTE physical channel, wherein the at least one LTE physical channel is not an LTE physical downlink shared channel (PDSCH) and is not an LTE physical downlink control channel (PDCCH);
communicating using the at least one LTE physical channel, wherein messages sent over the at least one LTE physical channel intended for a group have a group identifier associated with the group; and
