Wireless communication system

摘要

A first controller ( 5 ) of a master terminal (1) is configured to control a first transmitter (3) to divide the downlink slot (B) into a plurality of transmitting segments (tsg1 to tsgx) with a synchronizing signal contained in a segment signal of each of the transmitting segments (tsg1 to tsgx) and also to sequentially transmit the segment signals of the transmitting segments (tsg1 to t sgx ) on respective different frequency channels ( ch1 to chx ). A second controller (15) of each slave terminal (10) is configured to control a second receiver (4) to receive a segment signal on a variable frequency channel in the different frequency channels (ch1 to chx). Each second controller (15) is configured, after successfully receiving a synchronizing signal in a segment signal, to control a second transmitter (13) to transmit a wireless signal containing a response message during a pre-allocated uplink slot on a frequency channel corresponding to a transmitting segment of the successfully received segment signal.
