Abstract

The present invention relates to a system that includes a transmission/reception point and a user equipment having different configurations in inter-band and performs a TDD (Time Division Duplex) method.

Claims

1. 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), having different Uplink-Downlink (UL-DL) configurations, the method comprising:

receiving a physical downlink shared channel (PDSCH) transmission on the SCell in a subframe ‘

n−

ki’

, the n, k and I being an integer;

determining the interval ‘

ki’

between the reception of the PDSCH transmission on the SCell and a responsive A/N transmission, the interval being determined based on a reference UL-DL configuration for the SCell; and

transmitting the A/N responsive to the PDSCH transmission on the SCell in a subframe ‘

n’

according to the interval,

wherein the reference UL-DL configuration for the SCell is determined based on a PCell UL-DL configuration and SCell UL-DL configuration pair in Table 1-1 below;
