Abstract

Certain embodiments of the present disclosure provide an adaptive technique to determine size of a ranging back-off window according to a load of ranging channel. By applying an adaptive increase of the back-off window size, a probability of collision between ranging codes within a same transmission opportunity can be alleviated, and the ranging channel load can be decreased more efficiently than in the case of a standard non-adaptive back-off procedure.
