Method and apparatus for determining schedule timing interval

Provided are a method and apparatus for determining a schedule timing interval. The method comprises: demodulating a narrowband physical downlink control channel (NB-PDCCH) to determine a starting subframe of a scheduled narrowband downlink service channel (NB-PDSCH) or narrowband uplink service channel (NB-PUSCH), wherein the basis for determining the starting sub frame comprises at least one of the following: an ending subframe of the NB-PDCCH, an ending sub frame of a search space in which the NB-PDCCH is located, resource allocation within a scheduling window and a schedule timing interval instruction. By means of the technical solutions, the problem of how to determine scheduling timing in a narrowband system is solved, the instruction overheads are saved, and the resource usage efficiency is improved.
