ABSTRACT:
In a communication system where a continuous reverse channel transmission is utilized by redundant transmission of Walsh codes, a current transmission rate is modulated onto Walsh code polarity. In particular, a remote unit operating at a particular transmission rate utilizing a continuous reverse channel transmission modulates the transmission rate by setting the polarity of each Walsh code depending upon the current or future data traffic channel rate. In communication systems where a Reference Coherent (RC) type transmission is utilized, the particular transmission rate is modulated onto the reference symbols (501-517) by setting the reference symbols (501-517) equal to a binary "1" or "0".
