Abstract:
A method, an apparatus, and a computer program product for wireless communication are provided where, at a first wireless node, a weighted average of a frame loss rate is determined for a plurality of frames transmitted from a second wireless node using a first codec; feedback is transmitted to the second wireless node based at least in part on the frame loss rate; and one or more frames are received from the second wireless node using a second codec, responsive to transmitting the feedback. Also, transmitting from a first wireless node a plurality of frames to a second wireless node using a first codec; receiving frame loss rate information from the second wireless node responsive to the transmitting; selecting a second codec, based at least in part on the frame loss rate information, and transmitting a second plurality of frames to the second wireless node using the second codec.
