Wireless communication system, wireless communication unit and method of synchronisation
First Claim
1. A method of synchronising a wireless communication unit in a communication system, the method comprising at said wireless communication unit the steps of:
- monitoring transmissions from a communication system;
processing frequency and/or timing information from the communication system;
the method characterised by the steps of;
transmitting frequency and/or timing information by said wireless communication unit;
receiving and processing said frequency and/or timing information transmitted by said wireless communication unit at a receiving portion of said wireless communication unit;
comparing frequency and/or timing information transmitted from the communication system to that transmitted by said wireless communication unit; and
synchronising said wireless communication unit if said comparison step does not yield a match.

Abstract
A method of synchronising a wireless communication unit in a communication system, the method comprising at said wireless communication unit the steps of: monitoring transmissions from a communication system and processing (400) frequency and/or timing information from the communication system. The method further includes the steps of transmitting (404) frequency and/or timing information by said wireless communication unit; receiving and processing (406) said frequency and/or timing information transmitted by said wireless communication unit at a receiving portion of said wireless communication unit. The wireless communication unit then compares frequency and/or timing information transmitted from the communication system to that transmitted by said wireless communication unit; and synchronises said wireless communication unit if said comparison step does not yield a match. A wireless communication unit and a communication system are also provided.

15. A wireless communication unit comprising a transmitter transmitting frequency and/or timing information, the wireless communication unit characterised by:
-
a receiver, operably coupled to said transmitter, receiving frequency and/or timing information transmitted from said communication system and said frequency and/or timing information transmitted from said transmitter of said wireless communication unit; and
a processor, operably coupled to said receiver and said transmitter, processing said frequency and/or timing information and determining a frequency and/or timing offset between said frequency and/or timing information from said communication system and said transmitter, and informing said transmitter of said offset. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22)
