Abstract
(EN)
Communication systems, apparatuses and methods for switching communication between an uplink communication path or circuit and a downlink communication path or circuit are described herein. Typically, as disclosed, the apparatus for switching between uplink and downlink transmission circuits being an RF circuit, comprises: a switch having a first port (306) coupled to an uplink circuit, and a second port (304) coupled to a downlink circuit; a power level detector (300) configured to measure a power level of signals propagating through the switch; and a processing device (112) configured to determine when to switch between the uplink communication path and the downlink communication path based on the measured power level; wherein the processing device (112) is further configured to: after determining when to switch between the uplink communication path and the downlink communication path, perform a verification process before switching between the uplink communication path and the downlink communication path; switch between the uplink communication path and the downlink communication path if the verification process succeeds; and not switch between the uplink communication path and the downlink communication path if the verification process fails.

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.
