Abstract

Various embodiments may be generally directed to resource allocation techniques for beam forming training. In one embodiment, for example, an apparatus may comprise logic for an access point (AP), at least a portion of the logic implemented in circuitry coupled to the memory, the logic to identify one or more resources available to support beamforming operations in a time interval, enable the AP to use the one or more resources in the time interval to interact with one or more allowed classes of station (STA) to perform one or more beamforming operations, and generate a frame for wireless transmission comprising a set of indicator bits encoded with an indication of the one or more resources. Other embodiments are described and claimed.
