摘要： A method in a first user equipment (121) for transmitting a beacon signal (140) to be detected by at least one second user equipment (122; 123) for Device-to-Device, D2D, communication in a wireless telecommunications network (100) is provided.

摘要： A frequency deviation estimator (20, 40) estimates an instantaneous frequency deviation in a received signal that includes pilot sub-blocks non-contiguously distributedin time across a radio block. Each pilot sub-block comprising one or more pilot symbols. The estimator (20, 40) is configured to select, from the pilot sub-blocks non-contiguously distributed in time across the radio block, a particular pilot sub-block for which to obtain an instantaneous frequency deviation estimate. The estimator (20, 40) applies a Fast Fourier Transform (FFT) or a Discrete Fourier Transform (DFT) to a set of contiguous received signal samples that spans multiple ones of the pilot sub-blocks, including the particular pilot sub-block as well as one or more assisting pilot sub-blocks neighboring that particular pilot sub-block. The estimator (20, 40) then obtainsan instantaneous frequency deviation estimate for theparticular pilot sub-block based on the resulting FFT or DFT outputs.
