METHOD AND APPARATUS FOR TRANSMITTING ACKNOWLEDGEMENT OF RECEPTION IN WIRELESS COMMUNICATION SYSTEM

摘要

One embodiment of the present invention relates to a method with which a terminal transmits an acknowledgement of reception in a wireless communication system, the method comprising the steps of: acquiring downlink control information (DCI) via an enhanced physical downlink control channel (EPDCCH); receiving downlink data via physical downlink shared channel (PDSCH); and transmitting an acknowledgement of reception on the downlink data via a physical uplink control channel (PUCCH) resource; and when the PDSCH is transmitted on a SCell (secondary cell) and the PDSCH is instructed by the EPDCCH, the PUCCH resource is determined on the basis of the transmit power control (TPC) field included in the DCI.

主权项

1. A method for transmitting a reception response in a wireless communication system, performed by a User Equipment (UE), the method comprising:
acquiring Downlink Control Information (DCI) via an Enhanced Physical Downlink Control Channel (EPDCCH); receiving downlink data on a Physical Downlink Shared Channel (PDSCH); and transmitting a reception response to the downlink data by using Physical Uplink Control Channel (PUCCH) resources, wherein if the PDSCH is transmitted on a Secondary Cell (SCell) and indicated by the EPDCCH, the PUCCH resources are determined based on a Transmit Power Control (TPC) field included in the DCI.
