Title:
METHOD FOR TRANSMITTING/RECEIVING UPLINK CONTROL CHANNEL IN FRAME STRUCTURE OF SHORT TRANSMISSION TIME INTERVAL AND DEVICE THEREFOR
Document Type and Number:
WIPO Patent Application WO/2018/048110
Kind Code:
A1
Abstract:
The present embodiments propose a method for transmitting an Ack/Nack of sPUCCH in response to the reception of short TTI-based Spdsch in a 3GPP LTE/LTE- Advanced system. Specifically, in the present embodiments, a base station sets, for each terminal, an offset value for setting a link between sPDSCH and sPUCCH, and transmits the set offset value to the terminal through upper layer signaling (RRC signaling), thereby enabling a terminal to use the offset value to allocate sPUCCH resources for transmitting an Ack/Nack in response to the reception of sPDSCH.
