The method includes transmitting to a base station in a primary cell (PCell) and a secondary cell (SCell), a TDD uplink (UL)/downlink (DL) configuration of the PCell having a DL subframe super-set or UL subset that are common in the SCell and the PCell and a TDD UL-DL configurationg differing from each other, receiving data at a first subframe in the SCell, and transmitting, when a UL subframe set of the SCell is a subset of a UL subframe of the PCell, a feedback corresponding to the data at a subframe predefined in association with the first subframe in the PCell according to the TDD UL-DL configuration of the SCell. The method supports both the self-scheduling and cross-carrier scheduling of the UE using carriers of different TDD configurations."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for transmitting uplink and downlink data in TDD system","description":"A method and an apparatus for transmitting uplink/downlink data on time division duplexing (TDD) carriers are provided.
