Title:
METHOD AND APPARATUS FOR ESTIMATING CHANNEL IN WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/221388
Kind Code:
A1
Abstract:
The present disclosure relates to a communication technique for combining a 5G communication system with IoT technology for supporting a higher data transmission rate than a 4G system, and a system thereof. The present disclosure can be applied to 5G communication and IoT related technology-based intelligent services (for example, smart homes, smart buildings, smart cities, smart cars or connected cars, health care, digital education, retail business, and security and safety related services). The present invention relates to a method and an apparatus for estimating an uplink channel of a base station in a wireless communication system, comprising the steps of: estimating a position of a wireless channel tap on the basis of a sounding reference signal (SRS) received from a terminal; determining an average power value of the wireless channel tap for each link between a transmitting antenna and a receiving antenna from and to which the SRS is transmitted; and estimating an effective channel frequency response (effective CFR) of a physical uplink shared channel (PUSCH) on the basis of the position of the wireless channel tap and the average power value of the wireless channel tap.
