Abstract: A method is provided for receiving a downlink control information (DCI) from a base station (BS) by a user equipment (UE) in a wireless communication system. The UE monitors a plurality of Physical Downlink Control Channel (PDCCH) candidates having a cyclic redundancy check (CRC) scrambled by a cell radio network temporary identifier (C-RNTI) and having a same payload size in a common search space and a UE-specific search space on a primary cell to receive the DCI from the BS. The common search space and the UE-specific search space are overlapped. When the UE is configured with a carrier indicator field (CIF), determining, by the UE, that only a PDCCH in the common search space is transmitted by the BS from among the plurality of PDCCH candidates. The UE receives a Physical Downlink Shared Channel (PDSCH) corresponding to the PDCCH in the common search space.

Abstract: A method is provided for transmitting Acknowledgement/Negative Acknowledgement (ACK/NACK) information in a wireless communication system. A User Equipment (UE) configures a Physical Uplink Control Channel (PUCCH) format 3 for transmission of the ACK/NACK information. The UE transmits the ACK/NACK information for downlink transmission in a downlink subframe set including M downlink subframes in one uplink subframe, wherein M>1. A plurality of serving cells are configured for the UE and include one Primary Cell (PCell) and at least one Secondary Cell (SCell). The UE transmits the ACK/NACK information using a PUCCH format 1b when a first condition is met that comprises a condition in case where the ACK/NACK information corresponds to one Physical Downlink Shared Channel (PDSCH) without a corresponding Physical Downlink Control Channel (PDCCH) received only on the PCell in the downlink subframe set and the ACK/NACK information corresponds to an additional PDSCH indicated by detection of one corresponding PDCCH.
