User equipment, pdsch a/n transmitting method thereof, transmission/reception point, and pdsch a/n receiving method thereof

A method for transmitting acknowledgement/negative acknowledgement (A/N) by a user equipment configured with at least two serving cells comprising a primary cell (PCell) and a secondary cell (SCell), the PCell and the SCell having different Time Division Duplex (TDD) Uplink-Downlink (UL-DL) configurations, the method comprising:

• transmitting first A/N in an uplink subframe determined by a reference TDD configuration for the SCell, the first A/N corresponding to a physical downlink shared channel (PDSCH) transmission on the SCell,
• wherein the reference TDD configuration for the SCell has a greatest number of uplink subframes from among one or more reference TDD configurations for the TDD UL-DL configurations of the PCell and the SCell in Table 1 below:
