Claim:
1. A small-scale base station comprising: a digital signal processor configured to generate subframes of a given number, based on a first physical cell identity (PCI) unique to the small-scale base station and by providing a portion of the subframes as blank frames into which no information is inserted, such that positions where the blank frames are provided at the subframes form a pattern unique to the small-scale base station; and a central processing unit configured to use the generated subframes and to control data communication with a terminal, wherein the central processing unit sets the first PCI to be different from one or more second PCIs unique to one or more adjacent small-scale base stations, respectively, by determining a value of the first PCI based on a calculation of remainders, the calculation using each of the one or more second PCIs and a count N of the one or more adjacent small-scale base stations, where N is an integer greater than or equal to one, and the digital signal processor obtains the positions of the blank frames among the given number of subframes, based on a calculation that shifts a remainder yielded by dividing the set first PCI by a subframe count, and generates the subframes having the blank frames of the pattern unique to the small-scale base station.
