METHOD AND APPARATUS FOR FRAME DETECTION IN A COMMUNICATIONS SYSTEM

A method of determining a boundary of a sub frame in a time division duplexing (TDD) system is provided. The method detects a power level of a signal on at least one radio frequency, the signal comprising at least one subframe. A time-domain correlation is done on the detected signal with a first re...

Zusammenfassung:A method of determining a boundary of a sub frame in a time division duplexing (TDD) system is provided. The method detects a power level of a signal on at least one radio frequency, the signal comprising at least one subframe. A time-domain correlation is done on the detected signal with a first reference signal, wherein the first reference signal represents at least one sub frame. The location in time of a boundary of the at least one sub frame of the detected signal is determined based on the correlation of the detected signal and the first reference signal.
