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 41):
A user equipment (UE), comprising:\n baseband circuitry to add Demodulation Reference Signals (DMRS) to a communication signal; and radio-frequency (RF) circuitry to transmit the communication signal within a subframe carrying information of a physical channel designated for vehicle-to-X (V2X) communication, wherein the subframe has a predetermined number N SC BW  of subcarriers in the frequency domain, and a predetermined number of Orthogonal Frequency Division Multiplex (OFDM) or Single Carrier-Frequency Division Multiple Access (SC-FDMA) symbols in the time domain; wherein the baseband circuitry is to map the DMRS to two or four of the said OFDM or SC-FDMA symbols, and wherein each OFDM or SC-FDMA symbol of the subframe has N SC BW  resource elements (REs) mapped by the baseband circuitry to the respective N SC BW  subcarriers of the subframe, and the each DMRS has a transmission pattern that occupies REs of a respective OFDM or SC-FDMA symbol carrying the DMRS of a predetermined periodic pattern.
