METHOD AND APPARATUS FOR SUPPORTING FLEXIBLY CHANGING DUPLEX DIRECTIONS OF SUBFRAME IN TDD SYSTEM

摘要

The present invention for a method supporting the flexible conversion of duplex directions in a subframe comprises a process scheduling uplink-downlink channel resources for user equipment (UE) and enabling a base station to control the distribution of uplink-downlink subframes in the frame structure of the base station; a process composing a transmission method in the subframe according to downlink control data transmitted by the base station and the duplex direction of the subframe in SIB1 backward uplink-downlink configuration and the current duplex direction of the subframe and enabling the base station to transmit and receive the uplink-downlink data for the UE in the subframe including a flexible-duplex direction; a process comprising the transmission method in the subframe according to the downlink control data transmitted by the base station and the duplex direction of the subframe in the SIB1 backward uplink-downlink configuration by enabling the UE to receive the downlink control data transmitted by the base station; and a process enabling the UE to receive the downlink data or enabling the UE to transmit uplink data according to the downlink control data transmitted by the base station. [Reference numerals] (201) Control the distribution of uplink-downlink subframes in the frame structure of the base station and schedule uplink-downlink channel resources for the UE;(202) Base station transmits and receives the UE uplink-downlink data. The invention comprises the process composing the CRS in the subframe according to the duplex direction of the subframe in the current duplex direction of the subframe and the SIB1backward uplink-downlink configuration for the subframe having a variable duplex direction
