Patent ID: 8432838

Claim:
In a situation of coexisting heterogeneous systems including a first system and a second system, in a method of establishing a time domain structure of a second frame used for a Time Division Duplex (TDD) mode of the second system, so that the second frame can coexist with a first frame for a TDD mode of the first system, the method of establishing a time domain structure of a frame comprising: an information acquiring step for acquiring type information of the first system being supported and information on a first ratio, wherein the first ratio corresponds to a ratio of a downlink section length of the first frame structure to an uplink section length of the first frame structure; a second frame structure establishing step for establishing a second frame structure for the second system based upon the acquired information; and a ratio determining step for determining a second ratio, wherein the second ratio corresponds to a ratio of a downlink section length of the second frame structure to an uplink section length of the second frame structure.
