Patent ID: 7649968

Claim:
A timing system for use in a wireless communication system, said timing system comprising: a digital baseband processing unit that generates low resolution timing signals; a primary clock generation system that provides a low frequency clock signal that is used as a reference clock signal for the digital baseband processing unit; and a wireless transceiver that provides a high frequency clock signal that is synchronous to the air interface and that is used by the wireless transceiver to produce a high resolution timing signals to control the timing of the wireless transceiver; wherein said digital baseband processing unit places one of said low resolution timing signals within a known first timing window of a first counter within said wireless transceiver, wherein said wireless transceiver places said high resolution timing signal that is synchronous with the wireless transceiver within a second timing window based on the first counter, a second counter for the high resolution timing signal is initialized by said one of said low resolution timing signals, said one of said low resolution timing signals falling in the middle of a known third timing window, said second counter begins as soon as said one of said low resolution timing signals is detected by a positive edge of the high frequency clock signal of the wireless transceiver.
