First Claim
Patent Images
1. A method, comprising:
- activating a beamforming training support operation;
selecting predetermined directions for transmitting one or more forward direction beamforming training frames, wherein each comprise a forward beam/sector direction identifier;
transmitting at least one of the one or more forward direction beamforming training frames in each of the selected predetermined directions;
receiving at least one reverse direction beamforming training frame, which includes one of the forward beam/sector direction identifiers, from one of the predetermined directions; and
transmitting at least one response frame including a reverse beam/sector direction identifier that was received in the at least one reverse direction beamforming training frame.

Abstract
A system for configuring antenna systems for selecting directional communication signals corresponding to other apparatuses. A directional communication signal may be selected as the result of a beamforming training operation coordinated between an initiating apparatus and a responder apparatus. Particular modes and/or features may be requested by initiating apparatuses that, for example, may be functionally-limited. The responder may take these requested modes and/or features into account when formulating a beamforming training set for transmission to the initiator.
