ABSTRACT:
In a mobile communication system, multiple transceivers perform radio communications in the same frequency band. A transceiver (700) comprises a first sync timing detection part (706) configured to detect sync timing for a desired signal transmitted from a counterpart transceiver; a second sync timing detection part (708, 710) configured to detect sync timings for one or more undesired signals from non-counterpart transceiver(s); an error information determination part (712) configured to determine error information based on the sync timings for the desired and undesired signals; a signal generating part (714) configured to generate a feedback signal containing the error information; a transmission timing determination part (722) configured to update transmission timing for a transmission signal including the feedback signal according to a control signal received from the counterpart transceiver; and a transmission part (736) configured to transmit the transmission signal to the counterpart transceiver according to the updated transmission timing.
