摘要： A method and an apparatus for acquiring an ultra-fast global navigation satellite systems (GNSS) initial position with peer assistance are disclosed. The apparatus includes a communication unit configured to receive assistance generated using a distance from a master terminal to a slave terminal and frequency error of a counterpart's terminal, a communication signal system configured to immediately receive immediately necessary information of the assistance, a Global Positioning System (GPS) receiver configured to rapidly search for a GPS satellite signal using the assistance and continuously track the GPS satellite signal so as to extract a pseudorange, and a computation processor configured to compute the position of the slave terminal using the assistance and the pseudorange. By this configuration, it is possible to perform fast initial position measurement as compared to the existing A-GPS technique, achieve direct communication between two GPS receivers regardless of presence/absence of a mobile communication network, and solve various limitations of the A-GPS technique.

摘要： A spread-spectrum signal receiver, a multipath signal super-resolution method thereof, and a recording medium thereof are disclosed. Using a least-squares based iterative multipath super-resolution (LIMS) algorithm, the spread-spectrum signal receiver accurately resolves multipath signals in a multipath channel environment so as to extract necessary information such that a rake receiver tracks the multipath signals more accurately. Since the LIMS technique has high resistance against noise and require less computation, it may be used to resolve the multipath signals in real time and to extract a first arrival path signal of a first arrival signal and may be easily implemented offline.

摘要： Techniques for reporting channel state information (CSI) are described. A user equipment (UE) may receive data transmission from one or more cells among a plurality of cells and may report CSI for each of the plurality of cells. In an aspect, the UE may generate CSI with different quantization granularity (e.g., different codebook sizes), or different frequency granularity (e.g., different subband sizes), and/or different time granularity (e.g., different reporting intervals) for different cells based on the performance impact of each cell for data transmission to the UE. The performance impact of each cell may be determined based on a long-term channel gain or received power of the cell at the UE. The UE may quantize the CSI for each cell based on the codebook size for the cell. The UE may generate the CSI for each cell based on the subband size and/or the reporting interval for the cell.
