Method and apparatus for base stations and subscriber units may allow for soft handoff of a CDMA reverse link utilizing an orthogonal channel structure. Subscriber units may transmit an orthogonally coded signal over a reverse link to the base stations. A given base station provides timing control of the timing offset of the reverse link signal. The timing offset may be an absolute timing offset or a differential timing offset. The absolute timing offset may be signaled using more bits than the differential timing offset. Subscriber units may receive power control commands from one or more base stations.
