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.

A receiver processes a data signal and provides an acknowledgement within a turnaround time through use of code block alignment, reduced complexity or increased processing time. In a first embodiment, a radio access network (RAN) node enables encoded information to be segmented into multiple code blocks and maps a group of code blocks to be aligned with orthogonal frequency division multiplexing (OFDM) symbol boundaries such that efficient receiver processing can implement processing pipelining. In a second embodiment, the transmitter can provide more time or reduce the complexity of the packet, such as by repetition of bits of code blocks of the encoded information or by reserving resource elements (REs) such that the receiver has effectively more time (or less complexity) to process the last or last few code blocks of the packet.

All data symbols used in data transmission of a modulated signal are precoded by switching between precoding matrices so that the precoding matrix used to precode each data symbol and the precoding matrices used to precode data symbols that are adjacent to the data symbol along the frequency axis and the time axis all differ. A modulated signal with such data symbols arranged therein is transmitted.
