Abstract
A method and apparatus are described for providing multimedia broadcast multicast services (MBMS) service feedback. A wireless transmit/receive unit (WTRU) may receive an MBMS service query message over an MBMS control channel and transmit an MBMS service response. The MBMS service query message and MBMS service response message may be radio resource controller messages. The MBMS service query message may include MBMS service identifiers which identify MBMS services that the WTRU is receiving or intending to receive. The WTRU may generate a report with MBMS service identifier index values, where each MBMS service identifier index value indicates a position of a service identifier corresponding to an MBMS service in the original query list that the WTRU is currently receiving or intending to receive. The MBMS service status query message may be received alone or along with a MBSFNAreaConfiguration message. The WTRU may respond within a predetermined or configured time limit.
