Abstract

In packet based communications, e.g., in cellular or mobile communications, information is formatted as transmission frames. The transmission frames have equal length or duration, and they have a common format. Each transmission frame includes a frame marker field, a signaling field and a communication field. The frame marker field delimits the transmission frame, the signaling field includes communications system information, and the communication field includes information for communication between a user and a base station.
