Methods and systems for variable rate broadcast with soft handoff
First Claim
1. An apparatus adapted for wireless communications, comprising a processor configured to:
- select a rate set, including a plurality of distinct data rates each associated with a transmission format; and
instruct a plurality of access points to transmit a broadcast content in accordance with the rate set, the rate set configured to allow broadcast packets transmitted by the access points according to distinct data rates and transmission formats to be incrementally combined.

Abstract
Embodiments described herein relate to providing variable rate broadcast services with soft handoff in wireless communications. In an embodiment, a plurality of access points (e.g., servicing various cells in a broadcast area) may transmit a broadcast content in accordance with a rate set. The rate set may include a plurality of distinct data rates each associated with a transmission format, configured to allow the broadcast packets transmitted by the access points to be incrementally combined (e.g., on a per-slot basis at a subscribing AT). The data rates and corresponding transmission formats in the rate set may be selected in relation to the supportable data rates of the cells in the broadcast area, as well as the requirements for supporting soft handoff in these cells.
