Abstract

This paper proposes a technology to improve the channel estimation accuracy in mixed numerology environment. We proposed that a method of resource allocation of reference signal, cyclic prefix insertion and detection of channel response. It is shown that the proposed scheme can reduce the received signal-to-noise power ratio by 2dB to achieve the required bit error rate at 10^-2.
