Abstract: Disclosed is a 5G or pre-5G communication system for supporting a data transmission rate higher than that of a 4G communication system such as LTE. The present invention relates to a method by which a simulator analyzes a radio wave environment in a wireless communication system, and the method of the present invention comprises the steps of: allowing a simulator to receive geographic information and position information by which a transmitter and a receiver can be positioned in the geographic information; generating, by the transmitter of the simulator arranged at a random position in accordance with the position information, radio waves for at least one direction of a sphere having a fixed radius; grouping into at least one group on the basis of a traveling route of the generated radio waves; setting each group as an operation unit (Warp/Wavefront) for a graphics processing unit (GPU); and analyzing a radio wave environment by using the GPU in which the operation unit is set.

Abstract: A network scheduling device and method are disclosed. The scheduling method comprises: determining whether a set condition for a transmission time interval (TTI) is satisfied, and, if the set condition is satisfied, storing in a memory, at each TTI until the set TTI elapses, a data array comprising the network state of the current TTI, the scheduler type selected at the network state of the current TTI, the network state of the next TTI, and the actual compensation value for the network state of the current TTI, and updating the parameters of the first neural network based on at least one of the data arrays stored in the memory, and, if the set condition is not satisfied, inputting the network state of the current TTI to the first neural network and selecting a scheduler using the output of the first neural network based on the input network state of the current TTI.

Abstract: A controller is provided. The controller creates a page table including page table entries including mapping information for translating a virtual address to a physical address. Each of the page table entries includes: a virtual page number, a physical frame number, valid information, and size information. The virtual page number is included in a virtual address, the physical frame number is included in a physical address, the valid information includes a first predetermined number of bits, and the size information includes a second predetermined number of bits. The first predetermined number of bits represents an address translation range in a page table entry or a number of page table entries to be grouped, and the size information represents a size indicated by each bit of the first predetermined number of bits.

Abstract: A data processing system and method for accessing a heterogeneous memory system including a processing unit are provided. The heterogeneous memory system includes a memory module and high bandwidth memory (HBM) including a processing-in-memory (PIM) circuit combined with a memory controller. The memory controller is configured to detect a data array required for an arithmetic operation from a memory module or the HBM by using a border index value when the arithmetic operation is performed by the PIM circuit of the HBM and generate a memory module command set and an HBM command set using physical address spaces respectively designated in the memory module and the HBM.
