Title: Method and system for alternating transmission of codec mode information
Inventor: BRUHN STEFAN
IPC: H04L69/14
Filed: 1999-09-03
Abstract: A communication system supports multiple source coding/channel coding schemes.  A mode indicator can be transmitted with payload data to inform the receiver of the particular scheme currently being employed. Similarly, a mode request can be transmitted to inform the receiver of a particular scheme to be employed for information to be transmitted on the return radio link. The rate of change of the mode indications and mode requests can be decimated so that they need not both be transmitted in each frame to thereby reduce the overhead capacity consumption associated with the transmission of mode information.  According to one exemplary embodiment, the mode indication and the mode request can be tramsmitted independently on alternating frames.
