| 20100142476 | Method for mapping downlink dedicated pilots to resource elements in extended cyclic prefix frame structure - A method for mapping downlink dedicated pilot frequencies of an extend cyclic prefix frame structure to physical resource blocks, applied in a long term evolution system, includes the following steps: the first downlink dedicated pilot frequency of each channel is mapped to the specific position of a physical resource block; other downlink dedicated pilot frequencies of the channel are mapping-processed according to the time domain interval, frequency domain interval and the preset regulation; the time domain interval is two or three OFDM symbols, the frequency domain interval is two sub-carriers of the same time domain. By defining the positions of pilot frequencies in the physical resource block, the public pilot frequency can obtain the information of all channels when a base station uses a beam pattern of more than four antennas. Making the channel information obtained by dedicated pilot frequencies contain the real channel information and the process-weight-value of a beam pattern, a UE does not need to obtain the transmission-weight-value of a beam pattern, such as to avoid the feedback cost of weight-values of a beam pattern. | 06-10-2010 |

| 20080263487 | Multi-Format Consistency Checking Tool - A method and system for performing consistency checking of one or more design representations having different design types. A translator for each design type obtains information from each design needed to evaluate rules that are design type-neutral.
