GROUP-BASED MACHINE TO MACHINE COMMUNICATION

摘要

Methods and apparatus are provided for performing group-based machine-to-machine (M2M) communication. Machine-type communication (MTC) wireless transmit/receive units (WTRUs) may operate in M2M groups. MTC WTRUs belonging to the same M2M group may receive a broadcast message with a time window on a channel dedicated for receiving data directed to an M2M group. The MTC WTRUs may wake up during the time window and may receive data directed to an M2M group on a dedicated channel. The broadcast message may be broadcasted via a broadcast server upon a request from an MTC server. The time window is allocated upon a request from an MTC server on behalf of the M2M group.

主权项

1. A machine-type communication (MTC) server for performing group-based communication, the MTC server comprising:
a processor configured to:
send a radio resource request for communicating with an MTC group that comprises a plurality of MTC wireless transmit/receive units (WTRUs);receive an indication of radio resources allocated for the MTC group;send, to a first MTC WTRU in the MTC group, information indicative of the radio resources allocated for the MTC group and a first time slot allocated to the first MTC WTRU; andsend, to a second MTC WTRU in the MTC group, information indicative of the radio resources allocated for the MTC group and a second time slot allocated to the second MTC WTRU.
