Methods and apparatus for synchronization in a wireless network

A communication network, comprising:

• a base station, said base station having
• an adjustable base station oscillator circuit outputting a base station clock signal,
• means for adjusting said base station oscillator circuit, and
• means for transmitting said base station clock signal;
• and
• a mobile station, said mobile station having means for receiving said base station clock signal,
• an adjustable mobile station oscillator circuit outputting a mobile station clock signal,
• means for comparing said mobile station clock signal to said base station clock signal and for generating a corresponding base station clock comparison output signal, and
• means for adjusting said mobile station oscillator circuit based on said base station clock comparison output signal.

A method of synchronizing a base station and a remote station in a communication network, comprising the steps of:

• generating timing information at the base station;
• transmitting said timing information from the base station to the mobile station;
• generating a clock signal at the mobile station;
• comparing said timing information and said clock signals at said mobile station;
• and
• adjusting said clock signal to match said timing information.

A method of synchronizing communication signals sent between a base station and a mobile station in a communication network, comprising the steps of:

• generating a first clock signal at the base station;
• comparing said first clock signal with a reference clock signal derived from a reference network;
• adjusting said first clock signal to match said reference clock signal;
• transmitting a signal to said base station from which the adjusted first clock signal can be derived;
• deriving said adjusted clock signal at the remote station
• generating a second clock signal at the remote station;
• comparing said first and second clock signals;
• adjusting said second clock signal to match said derived adjusted first clock signal;
• receiving periodic GPS pulse signals at the base station;
• and resetting a signal frame transmission cycle derived from said first clock signal upon receipt of a GPS pulse signal.

A method of synchronizing communication signals sent between stations of a communication network, comprising the steps of:

• generating a first clock signal at a first station;
• operating communication circuitry at said first station according to a first station frame transfer cycle matching said first clock signal;
• comparing said first clock signal with a reference clock signal derived from a reference network;
• adjusting said first clock signal to match said reference clock signal;
• generating a second clock signal a second station;
• operating communication circuitry at said second station according to a second station frame transfer cycle matching said second clock signal;
• comparing said first and second clock signals;
• and
• adjusting said second clock signal to match said first clock signal.
