METHOD OF PERFORMING FEEDBACK FOR MULTICAST AND BROADCAST SERVICE

摘要

A method of performing a feedback for a multicast and broadcast service (MBS) is disclosed. A Multicast Broadcast Service (MBS) feedback method includes, generating, by a base station contained in a multi-cell multicast broadcast single frequency network (MBSFN) zone, a ranging channel code for a multicast broadcast service (MBS) feedback, allocating the ranging channel code to a mobile station contained in a cell zone of the base station, and receiving the MBS feedback information based on the ranging channel code from the mobile station. So, an adaptive modulation and coding (AMC) is applied to the MBS according to the NACK feedback, such that a throughput of the MBS system increases.
