Abstract:
A network infrastructure system implements data sharing and processing by using a network infrastructure to which an application terminal or application server constituting an application domain is connected in a shared manner, includes a plurality of network infrastructure nodes storing, processing, sharing data, wherein each of the plurality of network infrastructure nodes includes a data processing module including a data transfer function, a data distribution function, a data processing function, and a data sharing function which are provided to at least one of the application terminal and the application server.
Abstract:
Provided is an adaptive greenhouse control method that can control a greenhouse to provide an optimized environment by automatically and daily adapting to an external environment and a type of the greenhouse. The method includes performing a P-Band setting operation of setting a P-Band to determine a degree of which a greenhouse window is opened according to a current greenhouse inside temperature based on a predetermined set temperature, performing a greenhouse control operation of controlling the degree of which a greenhouse window is opened according to the P-Band, performing a greenhouse environment parameter measurement operation of measuring a greenhouse environment parameter value applied to set the P-Band, performing a P-Band changing operation of changing the P-Band according to the greenhouse environment parameter value, and performing a greenhouse change control operation of controlling the degree of which a greenhouse window is opened according to the P-Band changed in the P-Band changing operation.
Abstract:
Disclosed are a method and an apparatus for transmitting and receiving a synchronization signal in a communication system. According to an exemplary embodiment of the present disclosure, a method of transmitting a first synchronization signal, performed by a base station in the communication system, may comprise generating a base sequence; generating a modified sequence by inverting polarity of the base sequence; mapping the base sequence and the modified sequence to a first frequency region having a frequency higher than a center subcarrier and a second frequency region having a frequency lower the center subcarrier, so that the base sequence and the modified sequence are symmetric centering the center subcarrier located at a center frequency of a frequency domain of the synchronization signal; and transmitting the synchronization signal comprising the base sequence and the modified sequence to a terminal. Therefore, performance of the communication system can be improved.
Abstract:
Disclosed is a method and an apparatus for device-to-device (D2D) multicast communication in a cellular mobile communication system. The method for D2D communication may include transmitting a server designation request message requesting registration as a server terminal to a base station, and transmitting service information using a D2D multicast or broadcast communication scheme based on a radio resource allocated by the base station.
Abstract:
Disclosed is a method and apparatus for scheduling in a cellular-based device-to-device (D2D) communication. The method of scheduling a cellular resource used in a base station for a D2D communication between terminals may include grouping, by a proximity coordinator, a cellular resource of an adjacent base station based on cell information of a base station, managing a resource to be allocated to the terminal and a resource allocated previously to the terminal based on the grouped resource, and allocating the grouped resource to the terminal based on information associated with the resource to be allocated and the previously allocated resource when a request for D2D communication between terminals located in different cells is received.
