Abstract:
An apparatus and operation method of a Base Station (BS) for allocating a radio resource in a Cognitive Radio (CR) wireless communication system includes, when a licensed system is activated, determining whether each of User Terminals (UTs) located in a cell satisfies Quality of Service (QoS). If all of the UTs satisfy the QoS, a binary message indicating ‘on’ is broadcasted to neighbor BSs. If at least one of the UTs does not satisfy the QoS, a binary message indicating ‘off’ is broadcasted to the neighbor BSs, and when the binary message indicating ‘off’ is received from at least one of the neighbor BSs, the binary message indicating ‘off’ is broadcasted to the UTs.
Abstract:
Methods of forming vertical nonvolatile memory devices may include forming an electrically insulating layer, which includes a composite of a sacrificial layer sandwiched between first and second mold layers. An opening extends through the electrically insulating layer and exposes inner sidewalls of the first and second mold layers and the sacrificial layer. A sidewall of the opening may be lined with an electrically insulating protective layer and a first semiconductor layer may be formed on an inner sidewall of the electrically insulating protective layer within the opening. At least a portion of the sacrificial layer may then be selectively etched from between the first and second mold layers to thereby define a lateral recess therein, which exposes an outer sidewall of the electrically insulating protective layer.
Abstract:
Disclosed is a display device with small thickness and good aesthetic exterior appearance, which comprises a liquid crystal display panel for displaying images; a backlight unit for supplying light to the liquid crystal display panel; and a support member for supporting the liquid crystal display panel and the backlight unit, wherein the support member comprises a set cover for receiving the liquid crystal display panel and the backlight unit, the set cover functioning as an external cover; and a guide frame for guiding the position of the liquid crystal display panel and backlight unit, wherein the guide frame and liquid crystal display panel are connected with each other by a connection member provided therebetween. At this time, the lower and lateral sides of the display device are covered without using upper and external cases to cover the upper edge of display device. Thus, the entire thickness of the display device is decreased; the bezel width of the display device is also decreased; and the entire step coverage of the display device is removed, whereby the front of the display device is recognized as one structure, to thereby allow the good aesthetic exterior appearance of the display device.
