Abstract:
1. A method of operating a Mobile Station (MS) for using a guard band as a subcarrier for signal transmission in a communication system supporting frequency overlay, the method comprising: searching for a first center frequency for a first Frequency Assignment (FA), the first center frequency located at a position corresponding to an integer multiple of a subcarrier spacing; after searching for the first center frequency, receiving information indicating the numbers n performing a first network entry process by using all subcarriers including the first additional subcarriers, wherein the first additional subcarriers are subcarriers for data transmission within the guard band, wherein a spacing between the first center frequency for the first FA and a second center frequency for a second FA adjacent to the first FA is an integer multiple of the subcarrier spacing; receiving information indicating the numbers n performing a second network entry process by using all subcarriers including the second additional subcarriers.
