Title:
METHOD AND DEVICE FOR TRANSMITTING AND RECEIVING NEW RADIO TECHNOLOGY (NR) PHYSICAL DOWNLINK CONTROL CHANNEL (PDCCH) IN WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/182802
Kind Code:
A1
Abstract:
A method and a device for transmitting and receiving a new radio technology (NR) physical downlink control channel (PDCCH) in a wireless communication system are provided. In one or a plurality of orthogonal frequency division multiplexing (OFDM) symbols in a slot, a terminal monitors a PDCCH transmitted by a base station, wherein the slot is used for a long term evolution (LTE) cell-specific reference signal (CRS), and the terminal receives, from the base station, in at least one OFDM symbol in the slot, a demodulation reference signal (DM-RS) for the decoding of the PDCCH. A resource element (RE) used for the DM-RS for the decoding of the PDCCH does not overlap with an RE used for a LTE CRS.
