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. By applying the method, the base station and the user equipment in the embodiments of the present invention, the object that the base station notifies the user equipment that a particular flexible subframe is an uplink subframe or a downlink subframe via signaling can be achieved, and the user equipment can communicate normally with the base station when knowing the feature of the flexible subframe.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method for configuring subframes in a time division duplex system, a base station and user equipment. Background technique [0002] The Long Term Evolution (LTE, Long Term Evolution) system supports Time Division Duplexing (Time Division Duplexing, TDD), that is, uplink (UL, Uplink) and downlink (DL, Downlink) use different time slots of the same frequency. The LTE TDD system can semi-statically configure the uplink-downlink configuration (Uplink-Downlink Configuration) according to the service type to meet different uplink-downlink asymmetric service requirements. In the LTE TDD system, the uplink and downlink ratios used are semi-statically configured and cannot be changed dynamically. This will result in a mismatch between the current uplink and downlink ratios and the instantaneous uplink and downlink traffic, thus making it ineffective to use resources, especially fo...
