Abstract: This disclosure describes methods, apparatus, and systems related to media access control (MAC) range extension. A device may cause to append a training field to each of one or more beacon frames. The device may cause to send the one or more beacon frames directionally using a sector sweep to one or more responder devices during a first interval. The device may determine an extended schedule element to be sent to the one or more responder devices, the extended schedule element including one or more directional antenna sectors to be used by the device during a second interval. The device may identify a first frame from a first responder device, during the second interval, wherein the first frame is received on a directional antenna sector of the one or more directional antenna sectors corresponding to an operating sector of the first responder device.

Abstract: Techniques are disclosed for implementing am Intelligent Distributed Relay (IDR). The IDR may advantageously use the best qualities of both amplify-and-forward and decode-and-forward solutions. The advantageously leverages the use of a digital signal processing (DSP) circuitry, which may decode the data and control information. The control information may be used to control IDR behavior (e.g., in the uplink and/or downlink directions) and to enhance its characteristics.
