Abstract
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.
