Abstract: A method performed by a first device includes communicating, by the first device, with a second device, a line of sight (LOS) determination request including a LOS indicator indicating that a LOS procedure is used in LOS characterization of a transmission between the first device and the second device; transmitting, by the second device, a first set of reference signals, via a first plurality of transmitting resources; and measuring, by the first device, a second set of reference signals, transmitted by the second device, via a second plurality of receiving resources. This method comprises of both embodiments when there is LOS characterization transmission between the first device and the second device, and when there is no LOS characterization transmission between the first device and the second device.

Abstract: A computer-implemented method for multi-user multiplexing for block transmissions by an electronic device includes generating a user signal that includes a number of first samples in the time domain. The number of first samples are generated based on a discrete-time baseband signal and a predetermined guard period. A discrete Fourier transform (DFT) operation is performed on the number of first samples to obtain a number of second samples in the frequency domain. An interleaving operation is performed on the number of second samples to obtain a number of third samples in the frequency domain. An inverse-DFT (IDFT) operation is performed on the number of third samples to obtain a number of fourth samples in the time domain. A time shifting is performed on the number of fourth samples to obtain a number of shifted fourth samples. A block transmission is sent using the number of shifted fourth samples.
