摘要: The present invention relates to a device and method for communicating in mobile communication system. provides carrier signal having plurality of frames. Each frame has time slots, each slot comprises transmission bits. A group slots are assigned channel. traffic burst symbols is transmitted over the channel by transmitting first preamble one second at least other slots. occupies fewer bits than preamble. apparatus telephony an RF includes modem receiving digitized PCM producing signal, unit with FDMA/TDMA carrying signals. At signals carries limited message including header field unique word voice associated telephone call. Another acquisition field.
