Title
(EN) Method and apparatus for switching in a TDD system
Abstract
(EN)

A method of switching a communication device between an uplink communication path and a downlink communication path is provided. The method measures a power level of signals on at least one radio frequency for one of the uplink communication path and the downlink communication path. The measured power level is compared with a threshold power level. Switching between an uplink circuit and a downlink circuit is based on the comparison between the measured power level and the threshold power level.
