ABSTRACT:
A bidirectional communication system, including a base station and a plurality of mobile stations, comprises a first unit which alternatively sets a number of transmitting time slots and a number of receiving time slots, each transmitting time slot used by the base station to transmit data to one of the mobile stations on a corresponding one of subchannels assigned for the mobile stations, each receiving time slot used by the base station to receive data from one of the mobile stations on a corresponding one of the subchannels. A second unit changes one of the transmitting time slots and the receiving time slots to a reversed-mode time slot related to a particular one of the mobile stations, whereby the base station uses both the reversed-mode time slot and a corresponding one of the transmitting time slots and the receiving time slots to transmit data to the particular one of the mobile stations or receive data from the particular one of the mobile stations.
