Title:
METHOD FOR CONFIGURING REFERENCE POINT INDEPENDENT OF COMMON RESOURCE BLOCK GRID, AND DEVICE THEREFOR
Document Type and Number:
WIPO Patent Application WO/2020/027472
Kind Code:
A1
Abstract:
Disclosed according to the present invention is a method for receiving a demodulation reference signal (DMRS) by a terminal in a wireless communication system. Specifically, the method may comprise: receiving a synchronization signal/physical broadcast channel block (SS/PBCH block); obtaining information about control resource set (CORESET) #0 from a PBCH included in the SS/PBCH block; receiving a physical downlink control channel (PDCCH) through CORESET #0; and receiving a physical downlink shared channel (PDSCH) scheduled on the basis of the PDCCH and a DMRS for the PDSCH, wherein when the PDCCH is addressed to a system information-radio network temporary identifier (SI-RNTI), a reference point for the DMRS is subcarrier #0 of the resource block (RB) having the smallest number, among RBs included in CORESET #0.
