In the disclosure, the UE performing D2D communication is capable to reuse a formula generating the initialization value of the current PUSCH scrambling sequence generator and the base station is capable to distinguish the D2D signal and the uplink data at the same, so as to avoid occurrence of the severe interference due to the same cell physical ID. The disclosure is capable to support the UE performing D2D communication inside or outside the cell coverage at the same time. | 2016-04-21 |

20160112224 | DETERMINING A REPRESENTATION OF AN ELECTRICAL SIGNAL - The invention relates to a method, systems, computer program, and computer-readable medium for reducing artefacts (speckling) which may appear to be noise/errors in a representation of an electrical signal. An Eye Pattern representation of a digital bit stream signal can be used for determining a range of signal quality characteristics, and can be generated from measurements of the proportion of ones and zeroes detected when sampling the signal at both at a reference data sampling position within a bit period and at a range of offset sampling positions. However, the speckling noise which typically exists in such an Eye Pattern reduces the confidence that can be placed in values for different signal characteristics which may be determined from the Eye Pattern. While speckling may be reduced by increasing the sampling frequency used to sample the signal, the present invention reduces speckling by using data gathered at the reference data sampling point to correct data gathered at each of the offset sampling positions. Thereby, the invention reduces the number of samples needed in order to reduce speckling to a particular level. | 2016-04-21 |
20160112225 | Measuring Waveforms With The Digital Infinite Exponential Transform - A method is performed of selecting a signal of interest from a compound signal. The method includes generating a matrix and initializing a first row of the matrix to zero. The compound signal is obtained as a digital waveform signal, with sampling rate S samples per second. For each sample of the digital signal, a new entry is recursively computed for the matrix. For each frequency bin in the matrix (where f is the center frequency of the bin) the value in the new row is computed by multiplying the value for that bin in the previous row by the complex number r*e | 2016-04-21 |
