Abstract

Aspects of the disclosure relate to wireless communication networks having a capability of controlling the mapping of reference signals onto a carrier based on one or more Doppler parameters. A demodulation reference signal (DMRS) is mapped to a carrier according to a pattern based on one or more Doppler parameters, such as a Doppler frequency and/or a rate of change of channel conditions. In a further example, if an initial transmission of an information packet fails due to a high Doppler scenario, the probability of success of the retransmission may be improved by altering the DMRS configuration to account for the high Doppler scenario. Other aspects, examples, and features are also claimed and described.
