Title:
METHOD FOR PERFORMING CHANNEL ESTIMATION IN WIRELESS COMMUNICATION SYSTEM AND APPARATUS THEREFOR
Document Type and Number:
WIPO Patent Application WO/2020/032773
Kind Code:
A1
Abstract:
Proposed is a method for performing channel estimation of a physical downlink control channel (PDCCH) in a wireless communication system. Specifically, the method performed by a terminal comprises the steps of: receiving a synchronization signal block (SSB) from a base station; receiving, from the base station, system information (SI) on the basis of the SSB; transmitting, to the base station, a physical random access channel (PRACH) preamble; receiving, from the base station, a response to the PRACH preamble; transmitting, to the base station, terminal capability information related to channel estimation; receiving, from the base station, information on a PDCCH monitoring interval; and performing the channel estimation on the basis of the information on the PDCCH monitoring interval, wherein the terminal capability information includes information on the maximum number of control channel elements (CCEs) capable of performing channel estimation for each PDCCH monitoring interval.
