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.

The MTC server of claim 6, wherein the radio resources are shared amongst the plurality of MTC WTRUs during the time window. 10. The MTC server of claim 6, wherein the time window comprises a plurality of time slots, and the processor is further configured to: allocate a first time slot within the time window for a first MTC WTRU in the M2M group;allocate a second time slot within the time window for a second MTC WTRU in the M2M group; andsend information indicative of the radio resources allocated for the M2M group and the second allocated time slot to the second MTC WTRU. 11. The MTC server of claim 6, wherein the processor is further configured to: receive data from the first MTC WTRU via the radio resources; androute the data to an associated MTC user. 12. The MTC server of claim 6, wherein the processor is further configured to: receive a page directed to the first MTC WTRU from an associated MTC user; andsend the page to the first MTC WTRU during a time slot allocated to the first MTC WTRU. 13. A method for a machine-type communication (MTC) server to perform group-based machine-to-machine (M2M) communication, the method comprising: determining an amount of radio resources needed for an M2M group to send data in an uplink via a radio access network, the M2M group comprising a plurality of machine-type communication (MTC) wireless transmit/receive units (WTRUs);sending a radio resource request to the radio access network on behalf of the M2M group, the radio resource request comprising an indication of the determined amount of radio resources; andreceiving an indication of radio resources and a time window allocated for the M2M group to send data, wherein the radio resources allocated for the M2M group comprises a channel that is dedicated to the M2M group during the time window for sending data in the uplink. 14. The method of claim 13, further comprising: allocating a first time slot within the time window for a first MTC WTRU in the M2M group; andsending information indicative of the radio resources allocated for the M2M group and the first allocated time slot to the first MTC WTRU. 15.
