Claim:
1. A communications method implemented in a communications node used in a communications system, the communications method comprising: transmitting, to one or more first user equipments (UEs), a first uplink-downlink (UL-DL) subframe configuration at least at a first time interval; and transmitting, to one or more second user equipments (UEs) included in said one or more first UEs, a secondary uplink-downlink (UL-DL) subframe configuration at least at a second time interval, wherein the secondary UL-DL subframe configuration contains information used for reconfiguring time division duplexing (TDD), wherein the secondary UL-DL subframe configuration indicates one of time division duplexing (TDD) UL-DL subframe configurations, wherein the secondary UL-DL subframe configuration is transmitted in downlink control information (DCI), and wherein the secondary UL-DL subframe configuration is repeated at least at a second time interval of one radio frame, and the DCI is transmitted in a first downlink subframe in a first half of the second time interval and a predetermined second downlink subframe in a second half of the second time interval.
