METHOD AND APPARATUS FOR MANAGING GROUP COMMUNICATIONS

摘要

A method and apparatus for managing group communications are disclosed. A base station may provide multimedia broadcast multicast service (MBMS) data for transmission to groups of wireless transmit/receive units (WTRUs). The WTRUs may be divided into groups based on a respective MBMS service to be received by each respective group. The base station may assign a respective logical channel for the respective MBMS service of each respective group. The base station may then transmit, to one of the groups, a group assignment message indicating physical resources for a transmission of MBMS data for the group's MBMS service. Also, the base station may further transmit MBMS data of the group's MBMS service using the respective logical channel of the group using the indicated physical resources. The physical resources may include subcarriers. Each respective group may have a respective assigned group identification. The base station may be an eNode-B.
