Herein disclosed is a bidirectional digital wireless system transmitting and receiving asymmetric transmission frames comprising: a mobile station (1A) for transmitting a plurality of uplink transmission frames (L1) each including a guard frame portion (DL-Guard) and a data frame portion (UL-DATA) carrying a main information segment; and a base station (2A) for receiving the uplink transmission frames (L1), and generating and transmitting a plurality of downlink transmission frames (L2) each including an information frame element carrying a subsidiary information segment to the mobile station (1A), whereby the base station (2A) is operative to divide the information frame element into a predetermined number (n) of information frame portions (DL Info (1) to DL Info (n)) respectively corresponding to the guard frame portions (DL Guard (1) to DL Guard (n)) of the uplink transmission frame (L1) with respect to time length, and generate and transmit a plurality of downlink transmission frames (L2) each including the information frame portions (DL Info (1) to DL Info (n)) collectively forming an information frame element (dl, No.3) carrying a subsidiary information segment to the mobile station (1A).
