Title:
METHOD FOR CONTROLLING TRANSMISSION/RECEPTION TIMING OF BASE STATION ANTENNA FOR TDD WIRELESS COMMUNICATIONS AND BASE STATION ANTENNA USING THE SAME
Document Type and Number:
WIPO Patent Application WO/2010/123229
Kind Code:
A3
Abstract:
A method for controlling a transmission/reception timing of a BS antenna for TDD wireless communications is provided, in which a control signal and an RF signal are separated from a modulated signal received from a BTS, a TDD synchronization signal is monitored from the received modulated signal, a periodic RF signal is checked from downlink transmission and uplink reception RF signals, an error between the TDD synchronization signal and the periodic RF signal is calculated, and a transmission/reception switching control signal is output according to the error.
