Publication number: 20240171245Abstract: Disclosed is a wireless communication system, specifically, an apparatus and method for configuring a primary cell carrier/secondary cell carrier (PCC/SCC) prioritization only based on extremely partial channel state information in a wireless communication system. Specifically, a method of operating a user equipment (UE) in a wireless communication system includes: transmitting a sounding reference signal (SRS) or channel state information (CSI) to a base station; receiving a signal from the base station on the basis of the SRS or the CSI; and estimating a number of multi-paths using a neural network for the received signal, wherein the estimating of the number of multi-paths includes: re-shaping the received signal; extracting a singular value of the reshaped signal; and estimating the number of multi-paths based on the extracted singular value.Type: ApplicationFiled: November 16, 2023Publication date: May 23, 2024Applicant: ELECTRONICS AND TELECOMMUNICATIONS RESEARCH INSTITUTEInventors: Jun Sik KIM, Woong Hee LEE, Minhoe KIM, Taewon SONG, Jung Im KIM, Soon Gi PARK, Sung Cheol CHANG, Sun Mi JUN, Yong Seouk CHOI
