Abstract  Abstract

PROBLEM TO BE SOLVED: To provide an ACK/NACK transmission method in a TDD-based radio communication system.

SOLUTION: An ACK/NACK transmission method includes the stages of: receiving M (M>2) downlink sub-frames linked with an uplink sub-frame n at each of two serving cells; determining four candidate resources on the basis of the received M downlink sub-frames; and transmitting an ACK/NACK response to the received M downlink sub-frames using one resource selected from four candidate resources in the uplink sub-frame n. The two serving cells are made up of first and second serving cells. Among the four candidate resources first and second resources relate to a PDSCH or an SPS release PDCCH releasing semi-static scheduling received at the first serving cell and third and fourth resources relate to a PDSCH received at the second serving cell.
