Method and system for delivering multicast/broadcast services in a half frequency division duplex wireless communication system

A method and system for delivering MBS in an H-FDD wireless communication system minimizes MBS bandwidth allocation and maintains appropriate balance between two H-FDD mobile device groups. Generally speaking, this is achieved by allocating a downlink bandwidth section for one group of mobile devices (e.g. Group 2) to MBS and allowing a subgroup of mobile devices (e.g. Group 1A) in the other group (e.g. Group 1) that subscribes to MBS to participate in the former group (e.g. Group 2) as required to identify and decode MBS data.
