ABSTRACT:
A method of operation of a communications system, having first (10) and second communications units (12) communicating frame divided information via a relay device (11). The second communications unit (12) transmits a timing signal (step 106) to the first communications unit (10), containing timing information of received timing signals from the first communications unit(10). The first communications unit (10) calculates a timing offset (step 114) for the combined timing delay for transmissions to and from the second communications unit via the relay device and transmits the timing offset (step 116) to the second communications unit. The second communications unit (12) adjusts its timing (step 122) according to the received timing offset. A communications system includes a frame number offset indicator (27) for performing timing synchronisation between the communications units.
