Abstract:
1. A device for communicating in a communications system, comprising, a receiver configurable in a plurality of states, wherein in each state the physical layer headers associated with received frames of information are usable to determine the format in which the received frames of information are to be decoded and are interpreted differently relative to the interpretation of the physical layer headers in another state, wherein the plurality of states includes: a speech state in which the physical layer headers indicate to the receiver to utilize speech decoding or fast associated control channel (FACCH) decoding for the information in the received frames; a comfort noise state in which the receiver generates comfort noise, and best-effort data is interleaved with the physical layer headers, wherein the physical layer headers indicate that speech, data, or packet associated control channel (PACCH) information is included in the received frames; and a speech possible state in which the receiver generates comfort noise, the physical layer headers indicate that speech or FACCH information is included in the received frames, and the receiver attempts to decode either speech or FACCH information, as indicated by the physical layer headers.
