The present invention is related to the method to reduce over a high speed downlink packet access (HSDAP) channel to transmit the uplink feedback signaling by the radio transceiver (WTRU) associated with the transmission of multimedia broadcast multicast service (MBMS) and the system . Node B may pre-allocate a time-frequency region or common channelization code for feedback. Triggering criteria for reporting a channel quality indicator (CQI), the WTRU is set to meet only a CQI to the Node B transmits the triggering criteria. Triggering criteria is the current operating CQI value or number from the node B, it may be based on the transport blocks reception statistics or a predetermined period of time in error. Feedback reduction method associated with ACK / NACK to the WTRU includes transmitting an indication of the average number needed to successfully decode the transmitted data, instead of transmitting the ACK / NACK for each transmission interval.
