Mobility management of multiple clusters within a wireless communications network
First Claim
1. A method of instructing access terminals with regard to how to handle a cluster collision in a wireless communication system, comprising:
- determining whether a first cluster and a second cluster within the wireless communication system are at least adjacent with each other, the first cluster including a first plurality of sectors and the second cluster including a second plurality of sectors, the first cluster carrying a given multicast session on a first resource unit of a downlink broadcast channel within each of the first plurality of sectors and the second cluster carrying the given multicast session on a second resource unit of the downlink broadcast channel within each of the second plurality of sectors; and
controlling a manner in which the first cluster and the second cluster carry the given multicast session based on the determining.

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 are at least adjacent, the network controls a manner in which the first and second clusters carry the multicast media.

22. A non-transitory computer-readable medium comprising:
-
at least one instruction to determine whether a first cluster and a second cluster within a wireless communication system are at least adjacent with each other, the first cluster including a first plurality of sectors and the second cluster including a second plurality of sectors, the first cluster carrying a given multicast session on a first resource unit of a downlink broadcast channel within each of the first plurality of sectors and the second cluster carrying the given multicast session on a second resource unit of the downlink broadcast channel within each of the second plurality of sectors; and at least one instruction to control a manner in which the first cluster and the second cluster carry the given multicast session based on the determining.
