(EN) METHOD AND APPARATUS FOR SWITCHING IN A TDD SYSTEM
(FR) PROCÉDÉ ET APPAREIL PERMETTANT LA COMMUTATION DANS UN SYSTÈME TDD
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.

(FR)
L’invention concerne un procédé permettant la commutation d’un dispositif de communication entre une voie de communication en liaison montante et une voie de communication en liaison descendante. Le procédé consiste à mesurer le niveau de puissance des signaux sur au moins une fréquence radio, sur une des voies de communication parmi la voie de communication en liaison montante et la voie de communication en liaison descendante. Le niveau de puissance mesuré est comparé à un niveau de puissance seuil. La commutation entre un circuit de liaison montante et un circuit de liaison descendante est fondée sur la comparaison entre le niveau de puissance mesuré et le niveau de puissance seuil.
