The serving base station may select terminals that may receive data from among a plurality of terminals through a MIMO-DSM algorithm and a user scheduling based on the feedback information. | 08-11-2011 |
20110244900 | DATA TRANSMISSION SYSTEM FOR DETERMINING DATA TRANSMISSION POWER USING A VIRTUAL CELL - A data transmission system that determines data transmission power using a virtual cell is provided. A base station may receive transmission data from a plurality of cooperative base stations positioned around the base station, and model terminals receiving an interference signal from the base station and the plurality of cooperative base stations into a virtual cell. The base station may calculate the influence of the interference signal transmitted to the terminal, using the virtual cell, and determine a transmission power for a plurality of frequency bands based on the interference signal. | 10-06-2011 |
20120021791 | METHOD FOR HANDOVER DECISION USING VIRTUAL SCHEDULER AND HANDOVER CONTROL DEVICE THEREOF - Each base station performs virtual scheduling that does not take cell association into account for each slot and actual scheduling that takes cell association into account to calculate difference in average transmission rates for each user terminal and stores them in a table. The difference in the average transmission rates for each user terminal is compared with a difference in average transmission rates for each user terminal received from a neighboring base station to determine a handoff decision for each user terminal. | 01-26-2012 |
20140109105 | INTRUSION DETECTION APPARATUS AND METHOD USING LOAD BALANCER RESPONSIVE TO TRAFFIC CONDITIONS BETWEEN CENTRAL PROCESSING UNIT AND GRAPHICS PROCESSING UNIT - An intrusion detection apparatus and method using a load balancer responsive to traffic conditions between a central processing unit (CPU) and a graphics processing unit (GPU) are provided. The intrusion detection apparatus includes a packet acquisition unit, a character string check task allocation unit, a CPU character string check unit, and a GPU character string check unit. The packet acquisition unit receives packets, and stores the packets in a single task queue. The character string check task allocation unit determines the number of packets in the packet acquisition unit, and allocates character string check tasks to the CPU or the GPU. The CPU character string check unit compares the character strings of the packets with a character string defined in at least one detection rule inside the CPU. The GPU character string check unit compares the character strings of the packets with the character string inside the GPU. | 04-17-2014 |
20150181489 | APPARATUS AND METHOD FOR RESERVED TRANSMISSION OF NON-REAL-TIME CONTENT IN HETEROGENEOUS NETWORK ENVIRONMENT - An apparatus and a method for reserved transmission of non-real-time content in a heterogeneous network environment are disclosed. According to the present disclosure, a method for performing reserved transmission of non-real-time content in a heterogeneous network environment comprises receiving a transmission reservation option from either a mobile terminal user or a server, collecting information on networks accessible by the mobile terminal and data transmission rate on a regular basis, performing scheduling of whether to transmit data over a currently accessible network, based on the received transmission reservation option and the collected information on the accessible networks and the data transmission rate, and repeating data transmission according to the scheduling until transmission of the content is completed. | 06-25-2015 |
