METHOD AND APPARATUS FOR TRANSMITTING UPLINK CONTROL INFORMATION IN A TIME DIVISION DUPLEX SYSTEM

摘要

Provided are a method and an apparatus for transmitting uplink control information in a wireless communication system. The apparatus of the present invention receives, from a base station and through a first serving cell, a physical downlink control channel to which an uplink grant is mapped; receives, from the base station and through a second serving cell, a physical hybrid automatic repeat request indication channel (PHICH); and transmits an uplink HARQ to the base station through a physical uplink shared channel (PUSCH) on the basis of the uplink grant. If a TDD uplink/downlink configuration of the first serving cell and a TDD uplink/downlink configuration of the second serving cell are not identical, the timing of receiving the PHICH is defined as the location corresponding to a downlink subframe of the first serving cell, and the sum of a PHICH reception timing and a PUSCH transmission timing is set as a minimum value.
