The present invention is related to a method and system for sending and reducing uplink feedback signaling by a wireless transmit/receive unit (WTRU) related to transmission of multimedia broadcast multi cast service (MBMS) data over a high speed down link packet access (HSDPA) channel. A Node B may pre-allocate a time frequency region or a common channelization code for the feedback. A triggering criterion for reporting a channel quality indicator (CQI) is set and WTRUs send a CQI to a Node B only if the triggering criterion is satisfied. The triggering criterion may be a current operating CQI value at the Node B, or based on erroneous transport block reception statistics, or a predetermined time period. A feedback reduction method related to ACK/NACK includes the WTRU sending an indication of an average number of transmissions needed to successfully decode the data instead of sending an ACK/NACK for every transmission interval.
