A method and apparatus for managing group communications are disclosed. A wireless transmit/receive unit (WTRU) may receive the same data using multiple-input multiple output (MIMO) transmission from each of a plurality of synchronized network nodes. The synchronized network nodes may transmit the same data in a synchronized manner. The WTRU may transmit feedback information, including negative acknowledgements (NACKs) and channel quality indicators, to a single one of the plurality of synchronized network nodes. In addition, the feedback information may not be transmitted to the other synchronized network nodes. In response to the transmitted channel quality indicators, the WTRU may receive the same data again from the synchronized network nodes. The synchronized network nodes may transmit the same data again in a synchronized manner. Further, the same data may be received by a plurality of WTRUs. Also, the WTRU may be in a group of a plurality of groups of WTRUs. |
