The transmission power of a retransmission packet is controlled in the event of a packet retransmission request being sent from a receiving side in a wireless mobile communication system supporting hybrid automatic retransmission request (HARQ) transmission. In a method of controlling transmission power of retransmission packets by a mobile terminal in a wireless mobile communication system supporting hybrid automatic retransmission request (HARQ) transmission, the method includes steps of receiving, from a base station, gain information associated with the sequence of the retransmission packets; determining, using the gain information, transmission power of one of the retransmission packets; and transmitting the retransmission packet with the determined transmission power.

Selon l'invention, la puissance d'émission d'un paquet de retransmission, est régulée, lorsqu'une demande de retransmission de paquet est envoyée par le côté réception d'un système de communication mobile hertzien compatible avec l'émission de demandes de retransmission automatique hybride (HARQ). Dans un procédé pour réguler la puissance d'émission de paquet de retransmission par un terminal mobile dans un système de communication mobile hertzien compatible avec l'émission de demandes de retransmission automatique hybride (HARQ), le procédé comprend les étapes suivantes: réception, de la part d'une station de base, d'informations de gain associées à la séquence des paquets de retransmission; détermination, au moyen des informations de gain, de la puissance d'émission de l'un des paquets de retransmission; et émission du paquet de retransmission avec la puissance d'émission déterminée.
