US 2006/0135162 A1 · Methods and apparatus for flexible forward-link and reverse-link handoffs

Abstract

The disclosed embodiments provide for methods and systems for selecting sectors for handoff in a communication system. According to one aspect, the method includes monitoring an indicia of transmit power on a plurality of RL control channels directed to a plurality of sectors, and selecting one of the sectors as a candidate for a RL handoff. The disclosed embodiments also provide for methods and systems for indicating a selected serving sector for handoff in a communication system. According to one aspect, the method includes sending a first signal to a first sector to indicate the first sector as a serving sector for a forward-link handoff, and sending a second signal to a second sector to indicate the second sector as a serving sector for a reverse-link handoff.
