Method of recognizing frequency bandwidth of base station in a mobile communication system with frequency bandwidth scalability
First Claim
1. A method of recognizing a frequency bandwidth of a base station in a mobile communication system with frequency bandwidth scalability where base stations and mobile stations can communicate where transmission frequency bands of base stations and mobile stations having different frequency bandwidths are overlaid with one another, the method comprising the steps of:
- transmitting to a mobile station, by the base stations, first information including information about different frequency bandwidths of base stations at the same frequency position with the same center frequency over a minimum frequency bandwidth;
recognizing the presence of the base stations by comparing the first information from the base stations by the mobile station; and
detecting the frequency bandwidth information in the first information by the mobile station.

Abstract
A method is provided for recognizing the frequency bandwidth of a base station in a mobile communication system with frequency bandwidth scalability where the transmission frequency bands of base stations and mobile stations having different frequency bandwidths are overlaid with one another. The base stations transmit to a mobile station first information, including information about their frequency bandwidths at the same frequency position over a minimum frequency bandwidth with the same center frequency. The mobile station recognizes the presence of the base stations by comparing the first information from the base stations and detects the frequency bandwidth information in the first information.

15. A method of recognizing a frequency bandwidth of a base station in a mobile communication system with frequency bandwidth scalability where base stations and mobile stations can communicate in the case where the transmission frequency bands of base stations and mobile stations having different frequency bandwidths are overlaid with one another, the method comprising the steps of:
-
transmitting to a mobile station, by the base stations, first information including information about different frequency bandwidths of the base stations in the transmission frequency bands of the base stations for a predetermined time starting from the start of a transmission data frame on a time axis;
recognizing the presence of the base stations by comparing the first information from the base stations by the mobile station; and
detecting the frequency bandwidth information in the first information by the mobile station. - View Dependent Claims (16, 17, 18, 19, 20)
