Abstract: The disclosure relates to a 5G or 6G communication system for supporting higher data transmission rates than 4G communication systems such as LTE systems. A method performed by a receiving apparatus in a wireless communication system is provided. The method includes receiving reference signals from a transmitting apparatus, estimating respective channel component values of the reference signals, determining whether at least one reference channel component value which is equal to or greater than a first threshold is present among the channel component values of the reference signals, selecting a candidate beam based on the at least one reference channel component value in case that the at least one reference channel component value is present, determining whether a value of signal quality of the first candidate beam is equal to or greater than a second threshold, and selecting the candidate beam as a final beam in case that the value of signal quality of the candidate beam is equal to or greater than the second threshold.

Abstract: The present invention relates to a composition for enhancing reprogramming efficiency from somatic cells to induced pluripotent stem cells, comprising an mTOR activator, and a method for enhancing reprogramming efficiency by using same. In the method, reprogramming factors including OCT4, SOX2, c-Myc, and KLF4 are transduced into somatic cells, followed by treatment with an mTOR activator, thereby remarkably increasing reprogramming efficiency into induced pluripotent stem cells. Therefore, the composition and method can be used for effectively inducing the reprograming of somatic cells into induced pluripotent stem cells.
