METHOD AND APPARATUS FOR SETTING DETOUR PATH IN WIDEBAND HIGH FREQUENCY WIRELESS SYSTEM USING CENTRALIZED MAC PROTOCOL
First Claim
1. A controlling method of an apparatus for setting a detour path in a wideband high frequency wireless system using a centralized Media Access Control (MAC) protocol, the method comprising:
- receiving, by a first device, a beacon message from a piconet coordinator to verify information of the piconet coordinator;
transmitting, by the first device in response to the beacon message, information of the first device to the piconet coordinator, to be registered in the piconet coordinator;
transmitting, by the first device, a probe request to a second device and a relay device, wherein the relay device provides a detour path with respect to a direct communication path between the first device and the second device; and
receiving, by the first device, a response to the probe request from the second device and the relay device to verify information associated with the second device and the relay device.

Abstract
Provided is a method and apparatus for setting a detour path in a wideband high frequency wireless system using a centralized Media Access Control (MAC) protocol. Here, in a wireless system using the centralized MAC protocol where a time synchronization and a band allocation may be performed by a single central control unit, when a signal blockage occurs while a data communication is being performed via a direct path between a source device and a destination device, the detour path may be quickly provided.

7. A controlling method of an apparatus for setting a detour path in a wideband high frequency wireless system using a centralized MAC protocol, the method comprising:
-
generating, by a first device, a relay-beamforming command message for beamforming between the first device and a relay device, wherein the relay device provides a detour path with respect to a direct communication path between the first device and a second device; transmitting, by the first device, the relay-beamforming command message to the relay device; determining, by the first device, whether an immediate acknowledgement (IMM-ACK) to the relay-beamforming command message is received from the relay device; and performing, by the first device, beamforming between the first device and the relay device, when the IMM-ACK is received. - View Dependent Claims (8, 9, 10)
