Title:
METHOD AND APPARATUS FOR SUPPORTING FLEXIBLY CHANGING DUPLEX DIRECTIONS OF SUBFRAME IN TDD SYSTEM
Document Type and Number:
WIPO Patent Application WO/2013/162326
Kind Code:
A1
Abstract:
The present invention provides a method for supporting flexibly changing a duplex direction of a subframe in a TDD system including: adjusting, by a base station, uplink-downlink subframe distribution in a frame structure of the base station, and scheduling uplink-downlink channel resources for UE; receiving and sending, by the base station, uplink-downlink data of the UE; for a subframe with a variable duplex direction, configuring a transmission method in the subframe according to a current duplex direction of the subframe and a duplex direction of the subframe in SIB1 backward uplink-downlink configuration; receiving, by UE, downlink control information sent by a base station, for a subframe with a variable duplex direction, configuring a transmission method in the subframe according to a duplex direction of the subframe in SIB1 backward uplink-downlink configuration and the downlink control information sent by the base station; sending, by the UE, uplink data or receiving, by the UE, downlink data, according to the downlink control information sent by the base station.
