The present invention configures ACK/NACK information on multiple UL codeword transmission using a PHICH and at least one NDI, whereby the ACK/NACK information on the multiple UL codeword transmission is transmitted to a user equipment without additional PHICH resource allocation. The present invention extends the conventional HI codeword and/or arranged position on a signal constellation, thereby transmitting ACK/NACK information on multiple UL codeword transmission to a user equipment without additional PHICH resource allocation."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Apparatus and method of transmitting ACK/NACK information and apparatus and method of receiving ACK/NACK information","description":"An apparatus and method of transmitting ACK/NACK (acknowledgement/negative ACK) information in downlink and an apparatus and method of receiving the ACK/NACK information are disclosed.
