Predictive link adaptation for v2x communications

An apparatus for wireless communication of a first user equipment (UE), comprising:

• means for transmitting a signal to, or receiving the signal from, a second UE;
• and
• means for receiving information about the second UE from a sensor at the first UE or from a basic safety message (BSM);
• means for determining whether the apparatus and the second UE are in a line-of-sight (LOS) condition based on a correlation of the information about the second UE with one or more of a channel estimation, precoding matrix indicator (PMI) feedback, or rank indicator (RI) feedback.

An apparatus for wireless communication of a first user equipment (UE), comprising:

• a memory;
• and
• at least one processor coupled to the memory and configured to:
• transmit a signal to, or receiving the signal from, a second UE;
• and
• receive information about the second UE from a sensor at the first UE or from a basic safety message (BSM);
• determine whether the apparatus and the second UE are in a line-of-sight (LOS) condition based on a correlation of the information about the second UE with one or more of a channel estimation, precoding matrix indicator (PMI) feedback, or rank indicator (RI) feedback.

An apparatus for wireless communication of a first user equipment (UE), comprising:

• a memory;
• and
• at least one processor coupled to the memory and configured to:
• communicating with a second UE including transmitting or receiving a first transmission;
• and
• adapting a transmission parameter for a second transmission based on a predicted location of the apparatus or the second UE, the transmission parameter including at least one of a modulation, a code rate, a demodulation reference signal (DMRS) density, a precoder, a channel state information-reference signal (CSI-RS) transmission periodicity and a feedback rate.
