Abstract
A communication protocol provides diversity in UL and DL between a headset and a host device that transmits right and left audio data on separate channels. Each ear piece establishes an independent channel to the host device, and there is another channel between them. Each ear piece monitors not only its own channel to the host, but also the other ear piece's channel to the host. One ear piece may acknowledge the host device for a correctly received packet, which the other ear piece missed, on the other ear piece's channel to the host device, avoiding retransmissions. The eavesdropped data is provided to the other ear piece on the shared channel, providing for path diversity in DL. The ear pieces may exchange picked-up voice content to send to the host device, providing for path diversity in UL.
