Abstract
Methods, systems, and devices for wireless communications are described. A base station may transmit, to a user equipment (UE), a first demodulation reference signal for each of one or more sub-bands and configured in accordance with a first one or more demodulation reference signal configurations. The UE may select a second demodulation reference signal configuration from a respective set of second demodulation reference signal configurations for each of the one or more sub-bands and may transmit an indication of the second demodulation reference signal configuration for each of the one or more sub-bands. The base station may receive the indication and may transmit, to the UE, a second demodulation reference signal for each of the one or more sub-bands and configured in accordance with the second demodulation reference signal configuration for each of the one or more sub-bands.
