Abstract
Beamformed directional wireless communications are described that provide for spatial re-use that allows multiple pairs of peer-to-peer (P2P) links to communicate simultaneously over the same channel in the same spatial vicinity, without contention, and independent of centralized control. The spatial re-use improves network throughput by sharing spectrum resource among multiple links. Beamformed training includes obtaining best sector and least sector information by all stations. Prior to performing an independent P2P communication, antenna array sector information is checked, to assure that the sector to be selected is not impinging interference on other P2P interactions, then a request is made to a target station. The target station also refers to its sector information, and if no conflict is found it accepts and acknowledges the request, upon which it receives the P2P communication.
