Abstract

Methods, systems, and devices for wireless communications are described. A reference signal distribution scheme described herein may allow for the benefits of orthogonal cover codes, and improve mechanisms to identify and address resulting carrier frequency offset. Techniques are described for distributing reference signals (e.g., demodulation reference signals) over a set of resources. The reference signals may be arranged in equi-spaced clusters, where groups of the reference signals per cluster are spaced according to a first timing offset, and where each cluster may be spaced according to a second timing offset. The network may configure the reference signal distribution scheme at various user equipments, indicating values for the timing offset. The user equipments may transmit reference signals according to the indicated scheme.
