A wireless communication apparatus, system or method to perform directional wireless transmission (e.g., directional mmW) after establishing one or more routes. When valid routes are not available for sending route discovery, then sector sweeping (SSW) is performed which combines a routing request with the SSW frame sent in multiple sector directions for receipt by neighboring stations. These neighboring stations obtain the information from the SSW and its appended routing request and respond back to the initiator with an SSW to which may be appended a routing reply or a routing request. Beam refinement is performed by appending a training field onto a route request, which is responded to by appending a beam refinement reply onto a route reply.
