CA 2563733
A transmitter that may have marginal power availability is enabled to autonomously retransmit previously transmitted frames containing the same data. The transmitter sends an initial frame to a base transceiver station (BTS) and immediately retransmits the same frame without regard to any ACK/NAK transmission from the BTS. The retransmissions are accumulated in the receiver and decoded after a sufficient quantity of the frame is transmitted. After receiving the last retransmitted frame the BTS sends an ACK/NAK to the transmitter that is accepted.
Selon l'invention, un émetteur pouvant présenter une disponibilité de puissance marginale peut retransmettre de manière autonome des trames transmises précédemment contenant les mêmes données. L'émetteur envoie une trame initiale à une station d'émission-réception de base (BTS) et retransmet immédiatement la même trame indépendamment d'une quelconque transmission d'ACK/NAK de la BTS. Les retransmissions sont accumulées dans le récepteur et décodées après transmission d'une quantité suffisante de la trame. Après réception de la dernière trame retransmise, la BTS envoie un ACK/NAK à l'émetteur qui est accepté.
