Title:
METHOD AND APPARATUS FOR TRANSMITTING PDCCH ON BASIS OF DFT-S-OFDM IN WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/130562
Kind Code:
A1
Abstract:
A method for receiving a physical downlink control channel (PDCCH) by a terminal on the basis of discrete Fourier transform spreading orthogonal frequency division multiplexing (DFT-S-OFDM), in a wireless communication system according to an embodiment may comprise the steps of: receiving, from a base station, a first PDCCH including first downlink control information (DCI) containing information about size used in DFT precoding having been applied to a second PDCCH; acquiring the first DCI by performing blind decoding of the first PDCCH; receiving the second PDCCH including second DCI from the base station; and acquiring the second DCI by performing blind decoding of the second PDCCH on the basis of the information that, contained in the first DCI, is about the size used in DFT precoding having been applied to the second PDCCH.
