Aspects of the present disclosure provide techniques for transmitting, receiving, and processing multi-user multiple input multiple output (MU-MIMO) signals for heterogeneous numerology systems. An exemplary method performed, for example, by a scheduling entity generally includes signaling an indication of numerology parameters to be used in transmitting first and second multi-user multiple input multiple output (MU-MIMO) signals to first and second user equipments (UEs) using shared resources and transmitting the first and second MU-MIMO signals to the first and second UEs, in accordance with the numerology parameters.
