METHOD FOR TRANSCEIVING CONTROL SIGNALS, AND APPARATUS THEREFOR

摘要

A method is presented for transmitting an acknowledgement/negative acknowledgement (ACK/NACK) signal by a user equipment (UE) in a wireless communication system. The UE is configured with a primary cell (PCell) and a secondary cell (SCell). The UE receives downlink control information (DCI) via a physical downlink control channel (PDCCH). The DCI including a first field for transmit power control information and a second field for ACK/NACK resource offset information. The UE receives downlink data via a physical downlink shared channel (PDSCH) based on the DCI. The UE transmits an ACK/NACK signal for the downlink data using an ACK/NACK resource. When the downlink data is received on the PCell, the ACK/NACK resource is determined by adding a lowest resource index of the PDCCH and a value of the ACK/NACK resource offset information. When the downlink data is received on the SCell, the first field includes ACK/NACK resource indication information.

1. A method for transmitting an acknowledgement/negative acknowledgement (ACK/NACK) signal by a user equipment (UE) in a wireless communication system, the UE being configured with a primary cell (PCell) and a secondary cell (SCell), the method comprising:
receiving downlink control information (DCI) via a physical downlink control channel (PDCCH), the DCI including a first field for transmit power control information and a second field for ACK/NACK resource offset information; receiving downlink data via a physical downlink shared channel (PDSCH) based on the DCI; and transmitting an ACK/NACK signal for the downlink data using an ACK/NACK resource, wherein, when the downlink data is received on the PCell, the ACK/NACK resource is determined by adding a lowest resource index of the PDCCH and a value of the ACK/NACK resource offset information, and wherein, when the downlink data is received on the SCell, the first field includes ACK/NACK resource indication information and the ACK/NACK resource is determined as an ACK/NACK resource indicated by the ACK/NACK resource indication information from among a plurality of ACK/NACK resources configured through a higher layer.
