Method and apparatus for spatial reuse by assistance of distributed devices over wireless system using directional antennas

摘要

Disclosed are a method for spatial reuse by support of distributed devices in a wireless communication system using a directional antenna, and an apparatus for the same. In the wireless communication system using the directional antenna, the method arranges an antenna with respect to a target device for communication before the distributed devices request a resource for communication, informs the target device or a central control unit in advance of a measurement result of a signal in MASs through the antenna, and requests a resource and receives a resource allocation based on the measurement result.

主权项

1. A method of a source device of a wireless communication system, the method comprising:
determining information corresponding to a pre-allocated resource including an available medium access slot (MAS) using a beacon message received from an adjacent device; transmitting, to a target device, a resource request message including the available MAS for a resource request; receiving, from the target device, a resource request reply message, the resource request reply message including,
when the resource request is approved, a field indicating allocation information with respect to the resource request, andwhen the available MAS has an interference, a field indicating interference information at the available MAS; and communicating, with the target device, using the available MAS when the field indicating the allocation information is included in the resource request reply message.
