Title (EN) SYSTEM AND METHOD FOR PACKET TRANSMISSION
(FR) SYSTÈME ET PROCÉDÉ DE TRANSMISSION DE PAQUETS
Abstract:
(EN) In a wireless communications system, packet error rate may be relatively low (e.g., five percent). Accordingly, receivers may successfully receive a first transmission the majority of the time. However, bandwidth may be used for retransmissions, which may be used relatively infrequently. Because retransmission packets do not necessarily have to be the same as transmission packets, transmission packets may be given more weight than retransmission packets. For example, transmission packets may be encoded with a higher bitrate than retransmission packets. In aspects, a transmitter may send a first transmission packet, including first data encoded with a first bitrate, and send a second transmission packet, including second data encoded with the first bitrate. The transmitter may send a first retransmission packet that includes the first data encoded with a second bitrate and the second data encoded with the second bitrate, and the first bitrate may be higher than the second bitrate.
(FR) Dans un système de communication sans fil, un taux d'erreur de paquets peut être relativement faible (par exemple cinq pour cent). Par conséquent, la plupart du temps, des récepteurs peuvent recevoir une première transmission. Cependant, une bande passante peut être utilisée pour des retransmissions, ladite bande passante pouvant servir relativement rarement. Puisque les paquets de retransmission ne doivent pas nécessairement être les mêmes que les paquets de transmission, les paquets de transmission peuvent peser plus lourd que les paquets de retransmission. Les paquets de transmission peuvent par exemple être codés avec un débit binaire supérieur à celui des paquets de retransmission. Selon certains aspects, un transmetteur peut envoyer un premier paquet de transmission contenant des premières données codées avec un premier débit binaire, puis un second paquet de transmission contenant des secondes données codées avec le premier débit binaire. Le transmetteur peut envoyer un premier paquet de retransmission qui contient les premières données codées avec un second débit binaire et les secondes données codées avec le second débit binaire. Le premier débit binaire peut être supérieur au second débit binaire.
