Disclosed is technology for supporting high-speed and low-latency performance in a 5G environment through implementation of a new reference signal transmission scheme appropriate for the 5G environment, that is, a mobile communication network environment for supporting high-speed and low-latency communication, which will appear afterwards.

Terminal for transmitting reference signal transmission device and method thereof

Disclosed is technology for applying a more differential QoS, that is, service quality to each communication service by implementing a differential QoS control in a radio section more precisely without any increase in complexity and load compared to a conventional bearer based QoS control method.

Base station, and QoS control method of wireless section

Disclosed is technology for applying a differential QoS, that is, service quality for each communication service by implementing a differential QoS control in a radio section in a more detailed unit without an increase in complexity and load compared to a conventional bearer-based QoS control method.

Terminal and QoS control method in wireless section

To consider a structure in which a radio module of a separate base station is extended/designed to have upper layer processing functions, as well as an RF processing function, the present invention defines a new fronthaul interface to reduce the fronthaul capacity required for transmitting data and a signal by a radio module in a separate base station.

Base station device, and method for transmitting data and signal

Disclosure is a BS apparatus and a method of transmitting a data packet capable of supporting smooth transmission of a data packet by defining a new fronthaul interface considering a structure of expanding/designing processing functions of a radio module of a 5G split BS including not only an RF processing function but also a processing function on a higher layer.

Base station apparatus and data packet transmission method

Disclosed is a technology for deriving an effect of meeting a demand of a scenario (for example, mMTC) supported by a 5G communication system and supporting service performance by implementing new uplink data transmission considering energy efficiency of a terminal and connection density of a base station.

Base station device, terminal apparatus and QoS control method in wireless section

The present invention relates to a technique of improving, when performing synchronization between a transmitting device and a receiving device communicating on the basis of a beamforming technique, an overall beamforming synchronization performance by enabling fast beam tracking in a receiving device.

Apparatus for transmitting synchronous signal, terminal for receiving synchronous signal and method thereof

The present invention relates to an uplink signal transmission for an access between a base station and a terminal in an MIMO system, and provides an uplink signal transmission device and an uplink signal transmission method, which can improve, using beamforming, uplink signal transmission performance.

Uplink signal transmission device and uplink signal transmission method

The present disclosure relates to a fibrous electrode and a supercapacitor including the same. In the fibrous electrode, a carbon nanotube sheet is spirally wound on a surface of an elastic fiber. Thus, the fibrous electrode may maintain a fiber shape, and an electrical connection structure in the carbon nanotube sheet may not be damaged by deformation of the elastic fiber. That is, the fibrous electrode may be reversibly changed to maintain excellent electrical conductivity. In addition, the fibrous electrode has a fiber shape having a diameter of hundreds of micrometers, and thus the fibrous electrode may be light and may have excellent durability and excellent life span characteristics.

Fibrous electrode and supercapacitor using same

A fibrous electrode includes a carbon nanotube sheet which is coated on an elastic fiber and has a buckle structure. Thus, the fibrous electrode may maintain a fiber shape, may be light and small and may maintain excellent conductivity even when variously deformed. In addition, the fibrous electrode has high elasticity and thus is capable of being variously deformed (e.g., bent or stretched) and of being realized in the form of textile. As a result, the fibrous electrode may be effectively applied to flexible electronic devices such as implantable medical devices, microelectronic devices, Google glasses, smart watches, wearable computers, and smart clothing. Furthermore, a supercapacitor using the fibrous electrode includes flexible materials and thus is not easily damaged by external force such as tension or pressure. As a result, the supercapacitor may be applied to various fields because of its excellent flexibility.
