Synchronisation of the reverse link in a CDMA communications system

摘要

The present invention provides a method for reverse-link synchronization comprising:
transmitting from a mobile terminal to a base station a signal in a reverse-link direction wherein a timing used for said signal is set according to a transmission received in a forward-link direction from the base station;
at the base station:
detecting a synchronization sequence in the transmitted signal;
evaluating the timing of said transmitted signal; and

sending timing adjustment information as synchronization commands, the synchronization commands indicating timing adjustments in one-eighth of a chip increments, to the mobile terminal based on said evaluation.
