Abstract
In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus maybe a base station or a UE. In an aspect, the apparatus may determine locations for a number of DM-RS symbols to be transmitted in a scheduling unit of a channel configured in a slot/mini-slot, where a last DM-RS symbol maybe positioned one symbol prior to a last symbol carrying scheduled data. In another aspect, the apparatus may determine the locations for the DM-RS symbols based on a selection between a first set of predetermined DM-RS positions and a second set of predetermined DM-RS positions. In another aspect, the apparatus may determine the locations for the DM-RS symbols based on a set number of symbols, wherein the determined locations are spaced apart according to the set number of symbols. The apparatus may transmit the DM-RS symbols based on the determined locations.
