Title
(EN) METHOD FOR MAPPING, TRANSMITTING, OR RECEIVING UPLINK CONTROL INFORMATION IN WIRELESS COMMUNICATION SYSTEM AND DEVICE FOR SAME
Abstract
(EN)

A method for mapping, as uplink data channel resource, uplink control information for a terminal configured to support multiple transmission time interval (TTI) lengths in a wireless communication system, according to one embodiment of the present invention, wherein the method is carried out by the terminal, comprises the steps of: mapping an encoding symbol for a rank indicator (RI) on each resource element, in an ascending order of a frequency index beginning with a resource element of the minimum frequency index, from on a second symbol adjacent to a first symbol onto which an uplink reference signal is mapped in an uplink data channel resource in a TTI having a specific length from the multiple TTI lengths; and mapping an encoding symbol for a channel quality indicator (CQI) or a precoding matrix indicator (PMI) on each of the resource elements, in an ascending order of the frequency index beginning with the resource element of the minimum frequency index or in a descending order of the frequency index beginning with a resource element of the maximum frequency index, from on a specific symbol of the uplink data channel resource.
