Patent ID: 8837455

Claim:
A method for communicating, comprising: sending, by a base station, a service in one or more subframes that are designated as specific subframes, the specific subframes being selected from one or more radio frames that are designated as specific radio frames, the specific radio frames being selected from a time unit, wherein the time unit comprises 2 M radio frames, each of the radio frames contains a number R of subframes that can be allocated to carry the service, where R is a natural number, and M is a nonnegative integer; and sending, by the base station, position information of the specific radio frames in the time unit and position information of the specific subframes in the specific radio frame on a transport channel which is mapped to a physical shared data channel; wherein the position information of the specific radio frames is represented by the quantity of the specific radio frames in the time unit; or the position information of the specific radio frames is represented by an interval between two specific radio frames in the time unit, and wherein the interval is 2 m , and 0≦m≦M, or the interval is the total number of the radio frames in the time unit divided by the number of the specific radio frames in the time unit.
