Abstract: Aspects of mobility management within a wireless communications network including a plurality of sectors are disclosed. In an example, the wireless communications network includes a first cluster of sectors with at least one target sector and at least one supporting sector. The multicast communication session is carried within both the target and supporting sectors. In another example, a second cluster can be included within the network for supporting the same multicast communication session that includes its own target and supporting sectors. In this example, the first cluster transmits multicast media on a first interlace-multiplex (IM) pair of a downlink broadcast channel (BCH) and the second cluster transmits multicast media on a second IM pair of the downlink BCH. If sectors of the first and second clusters overlap, the network controls a manner in which the first and second clusters carry the multicast media.

Abstract: Techniques for supporting broadcast/multiple transmission to multiple terminals with feedback and rate adaptation are described. In an aspect, a combination of HARQ and at least one shared feedback channel may be used to support broadcast/multicast transmission. In one design, a base station may send at least one transmission of a packet to multiple terminals, one transmission at a time. The base station may receive feedback information (e.g., NAK) for the packet from the terminals on the shared feedback channel(s). The base station may determine whether to terminate the packet early and/or may select at least one transmission parameter for another packet based on the feedback information for the packet. In another aspect, a transport format for a broadcast/multicast transmission may be selected based on CQI information from terminals receiving the transmission. The terminals may send CQI information at a slow rate and/or only certain terminals may send CQI information.
