Abstract  Abstract

PROBLEM TO BE SOLVED: To provide transmission and reduction method and system of uplink feedback signaling from a wireless transmission and reception unit (WTRU) related to multimedium broadcast multicast service (MBMS) data transmission on a high speed downlink packet access (HSDPA) channel.

SOLUTION: A node B may preassign a time frequency region or a common channelization code for feedback. A trigger reference reporting channel quality indicator (CQI) is set and a WTRU transmits a CQI to the node B only when a CQI trigger reference is not satisfied. The trigger reference may be the curent operation CQI vale of the node B or a value based on the statistic of reception error of transfer block or a predetermined time. A feedback reduction method related to ACK/NACK includes to transmit the display of average number of transmissions required for decoding the data successfully in place of transmission of ACK/NACK from the WTRU every transmission interval.
