1. A method, comprising:
- determining, by a base station, a subframe number of a flexible subframe;
sending, by the base station, a higher layer signaling that indicates the subframe number of the flexible subframe;
determining, by the base station, a feature of the flexible subframe identified by the subframe number, wherein the feature of the flexible subframe indicates whether the flexible subframe is uplink or downlink; and
sending, by the base station, the same downlink control information to at least two terminal devices via a physical downlink control channel (PDCCH) within a common search space, wherein the downlink control information indicates the feature of the flexible subframe, the downlink control information is scrambled by a radio network temporary identifier (RNTI), and the RNTI used to scramble the downlink control information is the same for each terminal device of the at least two terminal devices.

Abstract
Disclosed are a method, a base station and a user equipment for subframe configuration in a time division duplex system. The method comprises: a base station determining a subframe number of a flexible subframe in a radio frame; the base station determining a feature of the flexible subframe corresponding to the subframe number, where the feature indicates that the flexible subframe is an uplink subframe or a downlink subframe; and the base station sending to a user equipment a first signaling via a downlink control channel, where the first signaling includes the feature of the flexible subframe corresponding to the subframe number.
