Method and system for reporting link state in a communication system
First Claim
1. A method for reporting a link state by a relay station in a communication system which includes a mobile station, a base station for providing a service to the mobile station, and one or more relay stations for relaying information between the base station and the mobile station, the method comprising the steps of:
- (1) detecting a physical channel from the base station and measuring a link state of a link with the base station based on the detected physical channel; and
(2) inserting information of the measured link state into a message and broadcasting the message through a wireless channel.

Abstract
Disclosed is a method and system for link state report in order to select an optimum route in a wireless communication system which includes a mobile station, a base station for providing a service to the mobile station, and one or more relay stations for relaying information between the base station and the mobile station. The method includes: detecting a physical channel from the base station and measuring a link state of a link with the base station based on the detected physical channel, and inserting information of the measured link state into a message and broadcasting the message through a wireless channel.

26. A system for reporting a link state in a communication system which includes a mobile station, a base station for providing a service to the mobile station, and one or more relay stations for relaying information between the base station and the mobile station, the system comprising:
-
a transmitter for detecting a base station preamble from the base station and one or more relay station preambles from said one or more relay stations, measuring link states based on the detected preambles, selecting one preamble from the detected preambles based on the measured link states, and broadcasting the selected preamble; and
a receiver for detecting the preamble from the transmitter, measuring a link state based on the detected preamble, and restoring information data transferred by the preamble. - View Dependent Claims (27, 28, 29, 30, 31, 32)
