Disclosed is an apparatus for determining transmit power of an uplink frame transmitted from a subscriber station to a base station and transmitting data in a mobile communication system in which a downlink frame, transmitted from the base station to the subscriber station, and the uplink frame are time division-duplexed (TDD). The apparatus includes a receive power measurement unit for measuring receive power of signals received from the base station; a transmit power controller for determining the transmit power of the uplink frame from the receive power measured by the receive power measurement unit and information related to receptions of an uplink frame, which is received from the base station; and a transmission radio frequency processor for performing radio processing so that the uplink frame is transmitted according to the transmit power determined by the transmit power controller.

L'invention concerne un dispositif servant à déterminer la puissance de transmission d'un bloc amont transmis depuis une station d'abonné jusqu'à une station de base et à transmettre des données dans un système de communication mobile dans lequel un bloc aval transmis depuis la station de base jusqu'à la station d'abonné, ainsi que le bloc amont sont duplexés par répartition dans le temps (TDD). Ce dispositif comprend une unité de mesure de puissance de réception servant à mesurer la puissance de réception de signaux reçus de la station de base, un contrôleur de puissance de transmission servant à déterminer la puissance de transmission du bloc amont à partir de la puissance de réception mesurée par l'unité de mesure de puissance de réception et l'information relative à des réceptions d'un bloc amont reçu depuis la station de base, et un processeur de radiofréquence de transmission servant à effectuer un traitement radio, de manière à transmettre le bloc amont en fonction de la puissance de transmission déterminée par le contrôleur de puissance de transmission.
