Abstract: One disclosure of the present specification provides a method of receiving a signal based on signal quality in a device to device (D2D) communication. The method may include: receiving a signal from the other terminal; measuring signal quality for each of a plurality of physical resource block (PRB) regions included in a frequency region in which the signal can be received; choosing a candidate PRB region for which demodulation is performed among the plurality of PRB regions on the basis of the measured signal quality; and performing demodulation on the candidate PRB region.

Abstract: A method of determining a position in a wireless communication system and apparatus thereof are disclosed. The present invention includes receiving system information including information on a reference cell and at least one neighbor cell from a location server, receiving positioning reference signals (PRSs) from the reference cell and the at least one neighbor cell using the system information, measuring reference signal time difference (RSTD) of each of the at least one neighbor cell for the reference cell, and transmitting the at least one measured RSTD to the location server. And, the RSTD is a relative timing difference between two cells. Moreover, the system information includes at least one cell for obtaining a system frame number (SFN) by the UE, as the reference cell or the at least one neighbor cell.

Abstract: The present specification relates to a reception apparatus and method for demodulating a signal in a wireless AV system. The reception apparatus estimates a transmission signal on the basis of an MMSE weight matrix. The reception apparatus divides the estimated transmission signal for respective reception antennas and performs an IFFT. The reception apparatus estimates and compensates for phase noise for the respective reception antennas on the basis of the signal for which the IFFT has been performed. The reception apparatus demodulates the estimated and compensated signal for respective streams.
