1. A communication method, comprising:
receiving, by the terminal, at least a part of a first subframe, wherein the first subframe consists of resource elements arranged in frequency and time domain, the first subframe consists of a first slot and a second slot, the second slot being subsequent to the first slot, the first slot consists of a first region of resource elements and a second region of resource elements, the second slot consists of a third region of resource elements, each of the resource elements in the first region precedes each of the resource elements in the second region in time domain, the first region includes a physical downlink control channel (PDCCH), and the second and third regions include a physical downlink shared channel (PDSCH) for data transmission;
determining, by the terminal, a location of a search space for a control channel in one of the second and third resource regions; and
obtaining, by the terminal, the control channel at least based on the location of the search space.
