First Claim
1. A method for allocating channel time in a wireless network that includes a plurality of stations, the method comprising:
- allocating channel time for at least one of the plurality of stations to transmit a beam for the purpose of determining link compatibility;
receiving, during the time allocated for determining link compatibility, a feedback signal from at least one of the other plurality of stations, the feedback signal including information indicating whether the beam would interfere with the at least one other station; and
allocating channel time for the at least one station to communicate data based on the feedback signal information.

Abstract
A method of searching a compatible beam link is disclosed. The present invention includes receiving a channel time for communicating data from a coordinator, the channel time being previously allocated for communicating data between other stations, determining an occurrence of interference during the allocated channel time, and transmitting a feedback signal to the coordinator, the feedback signal including an interference information indicating an occurrence of interference. According to embodiments of the present invention, stations of network search for compatible beams whenever necessary, whereby loads of energy management and operations of a main station can be reduced.
