Abstract:
A method and an apparatus for transmitting an uplink data and a user equipment is provided, the method includes: inserting multiple phase noise tracking reference signal (PT-RS) groups into a user data to be sent in time domain, according to a predefined interval; wherein each group of the phase noise tracking reference signal includes one or multiple PT-RS(s) of adjacent sampling points in the time domain; transforming the inserted multiple phase noise tracking reference signal groups together with the user data to be sent into frequency domain through a discrete Fourier transform (DFT) followed with a subcarrier mapping, and then with a transformation through an inverse fast Fourier transform (IFFT), to obtain an uplink DFT-S-OFDM waveform; and transmitting the uplink DFT-S-OFDM waveform. Embodiments of this disclosure may increase the accuracy of tracking the uplink phase noise and the possible system residual frequency shift and Doppler frequency shift, and may improve the system performance.

Claim (Index 8):
The apparatus according to  claim 7 , wherein a number of the PT-RS comprised in each PT-RS group inserted by the inserting circuitry is determined according to a downlink control information (DCI) sent by a base station.
