Abstract: PROBLEM TO BE SOLVED: To provide a flexible and efficient asymmetrical multiplex access protocol by assigning a slot to incoming link communication or outgoing link communication so as to optimize a transmission efficiency of a channel. SOLUTION: End user devices (mobile stations) 1-6 use one optional communication protocol among plural communication protocols for traversing an aerial interface 12 via antennas 10, 11 and to hold communication with a closest bas station 13. The base station 13 uses is own broadcast control channel(BCCH) to broadcast information to all the mobile stations 1-6 within a range at all times. The base station 13 and the mobile stations 1-6 use a traffic channel(TCH) to hold communication and the base station 13 sends a feedback signal by the use of an ancillary control channel(ACCH) simultaneously. Data sent through a traffic channel(TCH) are divided into packets and are sent with proper control bits by the use of a proper slot.
