Abstract: 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.

Abstract: An air purification module comprises a housing having an interior space provided with an air inlet and an air outlet, and an axial type blowing fan, mounted in the housing, for moving air from the air inlet to the air outlet. The air purification module further includes an air purifying unit, provided on a flow path of the air, for purifying the air and a guide for reducing the flow rate of the air between the blowing fan and the air purifying unit. The air purifying unit includes a filter provided between the blowing fan and the air outlet and a light source unit for providing light to the filter.

Abstract: Disclosed is an SMS management system equipped with an additional data transfer function. The SMS management system includes a message transmission module, wherein the message transmission module includes: a capacity calculating unit for calculating the volume of the message content entered by the message input unit and calculating a residual capacity by deducting the volume from the maximum capacity of a short message; an additional data processing unit for attaching additional data to the short message within the limit of the residual capacity calculated by the capacity calculating unit; and a message transmission unit for transmitting the short message with the attached additional data processed by the additional data processing unit to the recipient's mobile station number entered by the number input unit.
