Abstract:
1. A method of synchronizing a wireless terminal with a base station in an OFDM wireless communication environment, comprising: receiving a signal comprising a set of tones from the wireless terminal, the set of tones comprising a first subset of equally-spaced non-contiguous tones and a second subset of contiguous tones, the first subset of equally-spaced non-contiguous tones and the second subset of contiguous tones having the same number of tones; determining an arrival time of the signal; comparing the arrival time of the signal to a target arrival time window; generating a timing correction command as a function of the comparison of the arrival time to the target arrival time window, the timing correction command used to instruct the wireless terminal to adjust timing control; and transmitting the timing correction command.
