Abstract

DC60 A method of communicating control information in a system that supports modulation schemes. Many schemes for voice or data communications and control information. To provide reverse compatibility, the provided control channel uses the modulation scheme currently in use in the system, for example the GMSK type modulation scheme. The traffic channel and the associated control channel are used. Linear modulation scheme with the same symbol rate. Channel Modulation Scheme The associated control uses a reduced set of modulation schemes used for the traffic channel. Likewise, it uses the signal process in the bands to indicate channel coding, audio coding. Speak, and the modulation type used for the burst sent to the receiving station. Methods of communicating control information in systems that support modulation schemes. Many schemes for voice or data communications and control information. to prepare for compatibility If a given control channel is reversed, it uses the modulation scheme used in the system at that time, for example the GMSK type modulation scheme. The traffic channel and the corresponding control channel are used. Linear modulation scheme with the same symbol rate. Channel Modulation Scheme The associated control uses a reduced set of modulation schemes used for the traffic channel. Likewise, it uses the signal process in the bands to indicate channel coding, audio coding. Speak, and the modulation type used for the burst sent to the receiving station.
