Abstract
A terminal communicates with a serving base station and at least one soft handoff (SHO) base station for soft handoff on the reverse link in a wireless communication system. In one design, the serving base station schedules the terminal for transmission on the reverse link, forms an assignment for the terminal, and generates signaling for the terminal. The assignment indicates communication parameter(s) to be used by the terminal for transmission on the reverse link. The signaling contains sufficient information to allow the SHO base station(s) to receive and process the transmission from the terminal. The serving base station sends the signaling via a backhaul to the SHO base station(s). Each SHO base station receives the signaling via the backhaul, receives the transmission from the terminal via the reverse link, and processes the transmission in accordance with the signaling to recover the data sent in the transmission.
