Abstract
A method and system for using power and timing estimates to acquire frame acquisition of a reverse CDMA carrier signal. The method includes providing at least one remote transceiver device acquiring a forward CDMA carrier signal, and the one remote transceiver device transmitting a reverse CDMA carrier signal modified to include a frequency associated with the forward CDMA carrier signal. A transceiver base station, in response to determining if the reverse CDMA carrier signal exceeds a reverse CDMA carrier signal threshold (RCCST), uses the frequency embedded in the modified reverse CDMA carrier signal to acquire phase of the reverse CDMA carrier signal. Achieving acquisition the transceiver base station signals a mode change to the remote transceiver. Otherwise, the transceiver base station signals the remote transceiver device to slip the reverse CDMA carrier signal a predetermined number of chips; and/or transmit the reverse CDMA carrier signal at a second power level.
