Patent ID: 7558359

Claim:
A method of wireless communication for use in a wireless communication system, the method comprising: receiving first-direction link voice information, first-direction link vocoder rate bits and information for a vocoder rate of second-direction link voice information through a first-direction link channel, wherein the first-direction link vocoder rate bits indicate a vocoder rate used by a remote station to encode the first-direction link voice information; decoding the first-direction link voice information using the first-direction link vocoder rate bits; measuring at least one channel quality metric of the first-direction link channel; generating information bits for a new vocoder rate of the first-direction link voice information corresponding to the at least one first-direction link channel quality metric; encoding the second-direction voice information using the received information for the vocoder rate of the second-direction link voice information; and transmitting, through a second-direction link channel, the encoded second-direction link voice information, second-direction link vocoder rate bits and the generated information bits, wherein the second-direction link vocoder rate bits are for a presently applied vocoder rate in the encoding.
