<p>Techniques for transmitting and receiving segmented broadcast messages to improve performance. At a transmitter, a broadcast message to be transmitted over a wireless channel is partitioned into a number of segments and a header is formed for each segment. Each segment header may include (1) a sequence number, (2) a first segment indicator, and/or (3) a last segment indicator. A segmented broadcast message is generated with the segments and their headers, and is transmitted multiple times to improve reliability. At a receiver, one or more message repetitions are received for the segmented broadcast message. Each received message repetition is processed to recover good segments, if any, for the broadcast message. The good segments from the received message repetition(s) are then combined to recover the broadcast message. The processing may terminate whenever all segments of the broadcast message have been recovered.</p> |
