DEVICES, SYSTEMS, AND METHODS FOR SYNCHRONIZATION OF BROADBAND WIRELESS COMMUNICATION SYSTEMS

摘要

Methods for synchronization of a time division duplex (TDD) frame at a remote station are provided. A remote station receives a time division duplex (TDD) frame from a base station The remote station determines a propagation delay between the remote station and the base station. The remote station synchronizes the TDD frame to a 1 PPS signal derived from a GPS module located at the remote station plus the propagation delay.

1. A method for synchronization of a time division duplex (TDD) frame in a remote station from a base station, the method comprising:
receiving a base station signal from the base station, the base station signal encapsulated in the TDD frame; determining a propagation delay of the base station signal from the base station to the remote station; and determining a start time of the TDD frame at the remote station based on a 1 pulse per second (PPS) signal of a global positioning system (GPS) module located at the remote station and the propagation delay to the remote station from the base station.
