COMMUNICATION METHOD IN WIRELESS COMMUNICATION SYSTEM ON BASIS OF CARRIER AGGREGATION

摘要

Disclosed is a communication method in a wireless communication system on the basis of a carrier aggregation. The communication method on the basis of a carrier aggregation comprises the steps of: receiving a PDSCH from a base station via a subframe n of a TDD cell; and transmitting, to the base station, a PUCCH including a response to the PDSCH via a subframe n+4 of an FDD cell. Accordingly, an HARQ process may be performed efficiently.

1. A communication method based on carrier aggregation, performed in a terminal, the method comprising:
receiving a physical downlink shared channel (PDSCH) from a base station through a n-th subframe of a time division duplexing (TDD) cell, wherein n is a natural number; and transmitting a physical uplink control channel (PUCCH) including a response to the PDSCH to the base station through a (n+4)-th subframe of a frequency division duplexing (FDD) cell.
