摘要:
Provided is an apparatus and method for simultaneously receiving data signals of two adjacent frequency allocation (FA) in a cellular environment. When there is another base station using an adjacent FA to an FA of the base station, a subcarrier mapper maps control information to subcarriers of predetermined sections such that a mobile station simultaneously receives data signals of the adjacent FAs. An inverse fast Fourier transform (IFFT) processor IFFT-processes data mapped to the subcarriers. Because two different BSs transmit the same data through independent paths, the mobile station can obtain a macro diversity gain. Also, it is possible to balance the loads of the two BSs.

Disclosed is a method for determining handover of a mobile station by a mobile station in a mobile communication system. The method includes measuring a downlink reference signal intensity of a serving base station; determining to perform scanning for measurement of reference signal intensities of the serving base station and neighbor base stations, when the measured downlink reference signal intensity of the serving base station is less than a reference value, negotiating with the serving base station for a scanning period and the number of scanning repetitions, measuring the reference signal intensities of the serving base station and the neighbor base stations, and resetting the reference value when a reference signal intensity of the serving base station is greater than or equal to reference signal intensities of neighbor base stations.

A cooker and methods of manufacturing and controlling the same. The cooker including a first coating layer that is a general ceramic enamel layer and a second coating layer that includes phosphorus oxide-based components are coated on a surface of a cavity corresponding to the inner surface of the cooking chamber. Therefore, the inside of the cooking chamber can be more easily cleaned.

A display apparatus includes a first substrate and a second substrate. The first substrate includes a light blocking layer and the second substrate includes a shutter part. The shutter part includes first, second, third, and fourth operators and a shutter. The first, second, third, and fourth operators are operated independently from each other in response to first, second, third, and fourth voltages, respectively. The shutter is connected to the first to fourth operators to be rotationally moved. Thus, the display apparatus display may display various gray scales.

An uplink scheduling method by a terminal which performs a communication service according to a semi-persistent resource allocation scheme in a Base Station (BS) of a mobile communication system. The uplink scheduling method includes generating resource allocation control information including a particular field set to a value predetermined according to the semi-persistent resource allocation scheme, code-masking the particular field of the resource allocation control information by using a Cyclic Shift (CS) value for a Multi-User Multiple Input Multiple Output (MU-MIMO) operation of the terminal, configuring a transport block including the code-masked resource allocation control information; and transmitting the transport block to the terminal. Therefore, the MU-MIMO can be implemented even in a Semi-Persistent Scheduling (SPS) scheme. When the BS provides a VoIP service, service delay, which may occur due to lack of resources, does not occur, and resources can be immediately allocated.

Disclosed herein are a multilayer ceramic capacitor and a method for manufacturing the same. The multilayer ceramic capacitor includes: a capacitor main body having dielectric layers and inner electrodes laminated therein; external electrodes and plating layers formed on a surface of the capacitor main body; and electroless plating layers formed between the external electrodes and the plating layers.According to the examples of the present invention, the electroless plating layer is formed before the plating layer is formed on the external electrode, thereby solving non-plating problems when the plating layer made of nickel or the like is formed on the external electrode. Therefore, soldering defects due to nickel non-plating or the like can be solved at the time of mounting, and thus, a multilayer ceramic capacitor having high reliability can be provided.
