Abstract

A preamble-based collision detection mechanism for use in wireless local area networks (WLANS), having one or more full-duplex (FD) stations. In addition, a new collision resolution estimation and scheduling mechanism is described for prioritized communication. These techniques can allow for more rapid collision detection and resolution, without the need of performing self-interference (SI) estimation. The techniques includes use of orthogonal preambles, in the time domain and/or frequency domain, into which FD stations embed priority information.
