Bidirectional digital wireless system transmitting and receiving asymmetric frames

A bidirectional digital wireless system using asymmetric transmission frames comprising:

• a mobile station for generating and transmitting a plurality of uplink transmission frames each including a guard frame portion and a data frame portion carrying a main information segment in a time division demultiplexing manner;
• said guard frame portion and said data frame portion being separated from each other with respect to time length;
• and
• a base station for receiving said uplink transmission frames, and generating and transmitting a plurality of downlink transmission frames each including an information frame element carrying a subsidiary information segment to said mobile station with reference to said uplink transmission frames in said time division demultiplexing manner, whereby
• said base station is operative to divide said information frame element into a predetermined number of information frame portions respectively corresponding to said guard frame portions of said uplink transmission frames with respect to time length, and generate and transmit a plurality of downlink transmission frames each including said information frame portions collectively forming an information frame element carrying a subsidiary information segment to said mobile station, and
• said mobile station is operative to receive said downlink transmission frame in a time division multiplexing manner so as to sequentially extract said information frame portions collectively forming said information frame element, and perform said subsidiary information segment in accordance with said information frame element thus extracted to ensure reliable and efficient communication with said base station.
