Abstract:
Implementations of this disclosure generally may relate to the field of wireless communications. More specifically, implementations described in this disclosure relate to different 3GPP LTE and LTE-A system enhancements to address the issue and support reliable V2X operation in the high mobility environments. Several solutions to improve the V2X system performance in the high mobility vehicular channel propagation conditions are described. Some aspects relate to the suggestion of a new DMRS patterns within individual subframes that promote more accurate CFO estimation. Moreover, another aspect provides DMRS mapping or puncturing patterns to transmit individual DMRS in a periodic pattern on respective OFDM/SC-FDMA symbols so that they do not occupy all REs of the OFDM/SC-FDMA symbols, respectively.

Claim (Index 39):
A communication device, comprising:\n radio-frequency (RF) circuitry to receive, from a user equipment (UE), a communication signal within a subframe of a physical channel designated for vehicle-to-X (V2X) communication, and baseband circuitry to apply a Fast Fourier Transform (FFT) of size N FFT _ RX =N FFT /m to the received communication signal corresponding to different Demodulation Reference Signals (DMRS), where N FFT  is the size of IFFT used by the UE to generate the received communication signal, and where m\u2208{2, 3, 4, . . . }; and where the baseband circuitry is to apply an FFT of size N FFT _ RX  to respective ones of m consecutive subparts of one of the DMRS within the received communication signal in the time domain to derive m sets of the DMRS symbols corresponding to respective resource elements (REs) of the subframe in the frequency domain for each of the m consecutive subparts of one of the DMRS in the time domain, and estimate the receive signal carrier frequency offset (CFO) using the m sets of DMRS symbols obtained for a respective one DMRS.
