First Claim
1. A method of joining a cell by using a proxy coordinator, the method comprising:
- requesting a second device to operate as a proxy coordinator from a first device positioned out of a beacon frame reachable area of the cell;
transmitting a time period to operate as the proxy coordinator allocated by a coordinator of the cell;
informing the first device that the second device operates as the proxy coordinator;
transmitting a cell join request to the proxy coordinator from the first device; and
transmitting a beacon frame including time allocation information from the coordinator to the first device through the proxy coordinator.

Abstract
A method of joining a cell by using a proxy coordinator. The method of joining a cell by using a proxy coordinator includes requesting a second device to operate as a proxy coordinator from a first device positioned out of a beacon frame reachable area of the cell, transmitting a time period to operate as the proxy coordinator allocated by a coordinator of the cell, informing the first device that the second device can operate as the proxy coordinator, transmitting a cell join request to the proxy coordinator from the first device through the second device, and transmitting a beacon frame including time allocation information from the coordinator to the first device through the second device.
