title = "An efficient CQI feedback resource allocation scheme for wireless video multicast services",
abstract = "In wireless multicast services, a base station (BS) requires channel quality indicator (CQI) feedback from subscribers in order to determine a proper modulation and coding scheme (MCS). However, as the group sizes increase, the required feedbacks also increase, which will cause more signaling overheads in uplink. This paper proposes an efficient CQI feedback resource allocation scheme for wireless video multicast applications. More specifically, when a BS is serving several multicast groups simultaneously, our algorithm determines the proper sizes of feedback sets for each multicast group so that the system performance, in terms of average number of multicast service supported subscribers, is maximized. Simulation results not only well demonstrate the advantages of our proposed scheme, but also match with theoretical analyses.",
