Abstract: Provided are a method of allocating a resource in a wireless communication system and an apparatus using the method. The method includes: measuring a variation of a data usage pattern or density of user equipments located in a region for providing a service; determining whether the variation is greater than or equal to a threshold; and determining a resource allocation type of the region for providing the service on the basis of the determination result.

Abstract: Provided are a cell selection method performed by UE in a wireless communication system and UE using the method. The method includes generating data use pattern information, the data use pattern information including an amount of data used for each moving speed of the UE, receiving data providing pattern information that informs an amount of data provided by the wireless communication system for each specific moving speed of the UE, determining an access type of the UE based on the data use pattern information and the data providing pattern information, selecting a type of a cell to be accessed according to the access type and selecting a cell from cells having the cell type.

Abstract: A concentrated photovoltaic receiver is exposed to concentrated sunlight so that the concentrated photovoltaic receiver generates electricity. The concentrated photovoltaic receiver is mounted on a solar receiver. The fluid is passed through a narrowed region within the solar receiver. The narrowed region is located adjacent to the concentrated photovoltaic receiver so that thermal energy is transferred from the concentrated sunlight to the fluid as the fluid passes through the narrowed region.
