Communication between a base station with multiple transmission antennas and a mobile station is provided. The base station and the mobile station may recognize or estimate, respectively, a channel between the base station and the mobile station, and update a previous codebook with a new codebook based on a variation of the channel. In this instance, the mobile station may provide feedback information to the base station using the new codebook, and the base station may generate a transmission signal for the mobile station using the new codebook and the feedback information.

Various exemplary embodiments of a carriage-type cabin are disclosed. One exemplary embodiment may include a chassis having wheels to allow movement, a hitch disposed in a rear side of the chassis to enable attachment to another vehicle, a floor plate disposed on the chassis, a cabin body disposed on the floor plate and forming an interior space therein where the cabin body includes an entry door and a window, and a staircase disposed in a front side of the chassis and configured to guide a user to conveniently ingress and egress through the entry door. The cabin body may include an internal frame disposed on the floor plate and forming a basic frame and an external frame disposed above the inner frame. The internal frame and the external frame may be spaced apart from each other so as to form an air passageway therebetween for allowing air to flow naturally. The cabin body may also include a support plate attached to the outside of the internal frame for blocking between an inner space and an outer space, an internal finishing material made of wood attached to the inner surface of the support plate, external finishing material made of wood attached to the external surface of the support plate so as to provide an environment-friendly look, and a canvas disposed over the external frame to block solar heat from directly reaching the internal frame.

A method for manufacturing a semiconductor device. In one example embodiment of the present invention, a method for manufacturing a semiconductor device includes various steps. First, a gate pattern is formed on a substrate. Next, a first oxide layer is formed on the gate pattern. Then, a second oxide layer, a first silicon nitride layer, and a second silicon nitride layer are sequentially formed over the substrate and the first oxide layer. Next, a first etching process is performed to remove horizontal portions of the first and second silicon nitride layers. Then, source/drain regions are formed in the substrate. Next, the vertical portions first and second silicon nitride layers are removed. Then, a third silicon nitride layer is formed over the second oxide layer. Finally, a second etching process is performed to remove horizontal portions of the third silicon nitride layer and the second oxide layer.
