Abstract

A method of user equipment (UE) in a wireless communication system. The method comprises receiving, from a base station (BS), a downlink signal including position information for orthogonal frequency division multiplexing (OFDM) symbols of a short physical uplink control channel (PUCCH), determining, based on the position information, a position of the OFDM symbols of the short PUCCH included in a slot, and transmitting, to the BS, the short PUCCH using the OFDM symbols based on the determined position.
