摘要:
A method and apparatus for transmitting/receiving reference signals in Long Term Evolution (LTE) and LTE-Advanced (LTE-A) systems includes determining whether a dedicated reference signal is detected in a current subframe; estimating, if a dedicated reference signal is detected in the current subframe, a data channel using the dedicated reference signal to receive data; and estimating, if no dedicated reference signal is detected in the current subframe, a data channel using a common reference signal detected in the current subframe to receive data. The transmission scheme uses a DeModulation Reference Signal (DM-RS) for channel response estimation. To secure backward compatibility of the LTE-A system, a Common Reference Signal is transmitted in normal subframes.

Effective and uniform driving of a large organic EL display panel is formed using a plurality of stripes for each of first electrodes and also for each of second electrodes. These stripes are electrically isolated from each other, which enables each group of pixels defined by a set of orthogonal stripes to be driven separately from the remaining groups of pixels. Efficient fabrication methods devised to construct the display panel are cost effective and suitable for mass production.
摘要:
A method of fabricating an organic EL display panel accomplishes pixelation without using a shadow mask, and without exposing active EL elements to solvents from photoresist, or developing and stripping solutions. A first electrode layer and an insulating layer are formed on a transparent substrate. Portions of the insulating layer are removed at predetermined regions using at least one laser beam. An organic function layer and a second electrode layer are then formed on the predetermined regions. The first electrode layer, the organic layer and the second electrode layer form a sub-pixel. Additional sub-pixels are formed using the same method.

摘要:
Coordinated multipoint communication is a technology for improving cell-edge performance for users in a cell-type mobile communication system. In order to enable a coordinated multipoint transmission/reception operation, a user equipment report of a local environment is required to select both coordinated communication modes and communication partners in evolved Node B (eNB) base stations. According to the present invention, a method is described for feeding back information from User Equipment (UE) to a serving base station to enable a coordinated multi-point transmission/reception operation. The information reported through the feedback is classified into two categories corresponding to received signal intensity information and received signal timing information. The UE may select one or both types of information from between the categories to provide feedback. In embodiments of the present invention, various overhead-reducing reporting formats are described.
