Abstract
(EN)
Disclosed are a mobile terminal and time division duplex system for controlling the receiving sensitivity of a TDD system. A power amplification device of the mobile terminal has a built-in second radio frequency bidirectional switch. The second radio frequency bidirectional switch is connected to a filter, a downlink low-noise amplification device and a transceiving device, respectively. The downlink low-noise amplification device is connected to the transceiving device. A baseband signal controls, according to a time slot state of the time division duplex system, the switching of the second radio frequency bidirectional switch in order to form different communication paths.

La présente invention concerne un terminal mobile et un système de duplexage à répartition dans le temps pour commander la sensibilité de réception d'un système de duplexage à répartition dans le temps (DRT). Un dispositif d'amplification de puissance du terminal mobile a un second commutateur bidirectionnel radiofréquence intégré. Le second commutateur bidirectionnel radiofréquence est connecté à un filtre, à un dispositif d'amplification à faible bruit de liaison descendante et à un dispositif d'émission-réception, respectivement. Le dispositif d'amplification à faible bruit de liaison descendante est connecté au dispositif d'émission-réception. Un signal de bande de base commande, selon un état de créneau temporel du système de duplexage à répartition dans le temps, la commutation du second commutateur bidirectionnel radiofréquence de façon à former différents chemins de communication.
