Method for demodulating information in a communication system that supports multiple modulation schemes

A method for communicating information between a base station and a mobile station comprising:

• communicating voice or data using a first linear modulation scheme;
• communicating in-band signalling information using a second linear modulation scheme which is different from the first linear modulation scheme;
• and
• demodulating the voice or data and the in-band signalling information using the same demodulator.

A method of communication between a base station and a mobile station comprising:

• modulating voice or data over a traffic channel using a first linear modulation scheme;
• modulating control information over a control channel that is associated with the traffic channel using a second linear modulation scheme which is different from the first linear modulation scheme;
• and
• demodulating the voice or data and control information using the same demodulator.

A demodulator comprising:

• means for demodulating a first set of information that are modulated using a first linear modulation scheme;
• and
• means for demodulating a second set of information that are modulated using a second linear modulation scheme, wherein the first and second linear modulation schemes have the same symbol rate, and wherein the second modulation scheme uses a reduced signal set of the first linear modulation scheme;
• and wherein the first set of information and the second set of information are demodulated using the same demodulator.

A method for communicating information, comprising the step of:

• modulating a first set of information using a first modulation scheme;
• modulating a second set of information using a second modulation scheme, wherein the first and second modulation schemes have the same symbol rate, and wherein the second modulation scheme uses a reduced signal set of the first modulation scheme;
• and
• demodulating the first set of information and the second set of information using the same demodulator.
