Abstract  Abstract

The present invention provides a mobile terminal for use in a spread spectrum CDMA communication system the mobile terminal comprising: means for receiving from a base station a base-pilot signal and a base-data signal each with a pseudo random chip code sequence; means for transmitting to the base station a remote-pilot signal and a remote-data signal each with a pseudo random chip code sequence; means for synchronizing the chip code sequence of the transmitted remote-pilot signal to the chip code sequence of the received base-pilot signal for enabling the base station to generate a range determination; means for receiving a range determination from the base station; code phase adjustment means responsive to a mode control means for adjusting a phase of the remote-data signal and remote-pilot signal; and the mode control means for selecting one of a plurality of operating modes of the mobile terminal; wherein the plurality of operating modes comprises a first mode in which the chip code sequence of the remote-pilot signal is synchronized to the chip code sequence of the received base-pilot signal a second mode in which the remote-data signal is range adjusted and a third mode in which the remote-pilot signal is range adjusted whereby the base station receives the range adjusted remote-data signal and the range-adjusted remote-pilot signal orthogonal to other range adjusted signals.
