Abstract: In a Multiple-Input Multiple-Output (MIMO) system including a large number of antenna ports, a base station such as a Node B communicates a total number of antenna ports by communicating the number of antenna ports per Channel State Information Reference Signal (CSI-RS) configuration and one or more CSI-RS configurations. A User Equipment determines the number of antenna ports from the information communicated by the base station by determining the number of CSI-RS configurations sent by the base station and multiplying that number by the number of antenna ports per CSI-RS configuration indicated by the base station.

Abstract: The present disclosure relates to a method for producing an oral disintegrating film by a 3D printing technology which utilizes a hot-melt pneumatic extrusion method, and when a mixture including a poorly soluble drug, a film-forming polymer, and a plasticizer confirmed in the present disclosure was produced as an oral disintegrating film using the production method of the present disclosure, it was confirmed that the production method was simplified because the production process became one process, the production costs were decreased, and a poorly soluble drug having a problem in that bioavailability deteriorated due to an existing low solubility could obtain excellent solubility. The production method of the present disclosure that solves these problems can be utilized for many poorly soluble drugs, and thus can be widely utilized as a new method of utilizing a poorly soluble drug in the pharmaceutical field.
