METHOD FOR TRANSMITTING OR RECEIVING A SIGNAL IN A WIRELESS COMMUNICATION SYSTEM AND APPARATUS THEREFOR Russian patent published in 2019 - IPC H04L5/00 

FIELD: wireless communication equipment.

SUBSTANCE: invention relates to wireless communication. According to one embodiment of the present invention, a method of receiving DCI through a UE includes steps, at which: picking-up information is received regarding the REG through the upper layer signalling; performing blind detection with respect to PDCCH in CORESET, which is configured by multiple OFDM symbols; and obtaining DCI from PDCCH.

EFFECT: when the acquisition information indicates the first value, the UE may perform acquisition such that only the REGs which are located in the same RB and correspond to the different OFDM symbols in the said CORESET are completed as 1 REG set, and when the acquisition information indicates the second value, the UE may perform acquisition such that the REGs, which are located in the same RB and correspond to different OFDM symbols, are configured as 1 REG set along with the REG, which are located in different RBs in said CORESET, and UE can perform blind PDCCH detection, assuming the same pre-coding for REG, which belong to the same REG set as a result of REG acquisitions.
