Claim Text:
1. A base station for communicating with a user equipment in a time division duplex manner based on an orthogonal frequency division multiplexing scheme, wherein physical transmission resources for the communication between the base station and the user equipment are divided into a plurality of consecutive frames in the time domain, each of the frames comprises a plurality of subframes, and the base station comprises: a cycle determination device which determines a cycle to which each subframe belongs, wherein the cycle consists of at least one subframe sequence, each of which complies with the same subframe distribution pattern; a judgment device which determines whether each subframe of each cycle is marked as a first state or a second state different from the first state according to an allocation pattern, wherein the allocation pattern marks each subframe of the cycle as the first state or the second state, the subframes marked as the first state are consecutive, and include at least one uplink subframe and at least one downlink subframe; and a communication control device which, in case of determining that the subframe is marked as the first state, enables the base station to communicate with the user equipment over the subframe according to a predetermined control mapping relation associated with the allocation pattern, and in case of determining that the subframe is marked as the second state, disables the base station from performing the communication relating to the user equipment over the subframe, wherein the base station complies with the Long Term Evolution-Time Division Duplex scheme, the number of subframes in the cycle being greater than that of subframes in one frame, and the number of subframes marked as the first state in the cycle being an integer multiple of that of subframes in the subframe sequence.
