摘要:
Techniques for selecting serving sectors and performing handoff for a terminal on the forward and reverse links are described. The terminal may obtain pilot measurements for pilots transmitted on the forward link and may update an active set based on the pilot measurements. The terminal may send a transmission (e.g., for pilot, signaling, etc.) on the reverse link and may receive channel quality information indicative of reverse link channel quality for the terminal at multiple sectors in the active set. The transmission may include pilot, and the channel quality information from each sector may include a pilot carrier-over-thermal ratio (pCoT) determined by that sector based on the pilot. The terminal may select a serving sector based on the channel quality information, interference information, and/or other information and may send a request for handoff (e.g., via a signaling message an/or an access probe) to the selected serving sector.
