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 33):
The UE of  claim 27 , 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 frequency contiguous transmission pattern that occupies all REs of a respective OFDM or SC-FDMA symbol carrying the DMRS;\n 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 wherein the N SC BW  REs are continuously indexed with index i\u2208{0, 1, . . . , N SC BW \u22121}; wherein the baseband circuitry is to puncture all REs of an OFDM or SC-FDMA symbol to which a DMRS has been mapped having an index j other than j(x)=k+m\u00b7x for x=[0, 1, . . . , \u2514N SC BW /m=1\u2518] where m\u2208{2, 3, 4, . . . 8}, and k\u2208{0, . . . , m\u22121}; and wherein the RF circuitry is to transmit with non-zero power on non-punctured REs of the OFDM or SC-FDMA symbol to which the DMRS has been mapped, and transmits with zero power on punctured REs of the OFDM or SC-FDMA symbol to which the DMRS has been mapped.
