1. A method, comprising:
- determining, by a base station, a subframe number of a 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, downlink control information to at least two user equipments (UEs) 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 UE of the at least two UEs.

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.
