摘要:
A method and a target node for preventing collisions between networks communicating based on a carrier sense multiple access/collision avoidance (CSMA/CA) scheme, are provided. The method includes synchronizing an object network with a neighboring network. The method further includes allocating, to the object network, a slot index based on a number of the networks, and a contention window (CW) size. The method further includes setting, for the object network, a back-off counter value based on the CW size. The method further includes reducing the back-off counter value based on a channel state of the object network, and the slot index. The method further includes transmitting data related to the neighboring network based on the back-off counter value.

An ultra-low power super-regenerative receiver and method thereof are provided. The ultra-low power super-regenerative receiver includes a quench waveform generator configured to generate a quench waveform. The ultra-low power super-regenerative receiver further includes a super-regenerative oscillator configured to generate an oscillation signal based on the quench waveform. The ultra-low power super-regenerative receiver further includes a bandwidth adjustor configured to control the quench waveform based on a bandwidth of a signal received by the ultra-low power super-regenerative receiver, to dynamically adjust a bandwidth of the oscillation signal.

An adaptive scheduling method and apparatus that adaptively perform scheduling based on a coordinated rank in a multi-cell communication system are provided. A master base station may schedule, with a first priority, master terminals, each of which has a preferred rank equal to a transmission rank of the master base station, and may transmit, to a slave base station, information associated with a group of scheduled master terminals. The slave base station may schedule, with different priorities, slave terminals based on whether a transmission rank of the slave base station is equal to the coordinated rank for the master base station.
摘要:
An OLED device is disclosed. The OLED device disposes a voltage divider and a switch unit in the output stage of a power supplier, thereby lowering the level of a supply voltage VDD, which is applied to a driver IC in an emission interval, below that of the supply voltage which is applied to the driver IC in a non-emission interval. Accordingly, the OLED device can reduce electric power consumption.

Provided is a method and apparatus for determining a downlink beamforming vector in a hierarchical cell communication system. Small base stations may determine transmit beamforming vectors of the small base stations so that interference from the small base stations may be reduced in a macro terminal. A macro terminal and small terminals may determine receive beamforming vectors based on the transmit beamforming vectors of the small base stations. A macro base station may determine a transmit beamforming vector based on effective channels to terminals using the receive beamforming vectors of the terminals.

An electroluminescent display device is provided that includes a panel having a plurality of scan lines, a plurality of data lines and a plurality of pixels formed at cross areas of the scan lines and data lines. A driving circuit may be provided to drive scan signals on the scan lines and data signals on the data lines. A frame control device may receive first display data, determine a total amount of current passing through each of the scan lines, and provide second display data to the panel based on the determined total amount of current.

The present relates to a dual panel apparatus including two panels driven simultaneously. The dual panel apparatus includes a first panel, a second panel and a data driver. The first panel has a plurality of pixels formed in cross areas of data lines and first scan lines. The second panel has a plurality of second pixels formed in cross areas of the data lines and second scan lines. The data driver provides compensating precharge current to one or more data line. The dual panel apparatus uses two panels as main display device and sub display device, and thus the unit cost of the dual panel apparatus is reduced.
