US Patent 11997185 Demodulator configuration based on user equipment signaling

Methods, systems, and devices for wireless communications are described. A base station may transmit an indication of a demodulator configuration to a user equipment (UE) for the UE to use that demodulator configuration for demodulating a multi-layer transmission from the base station. The base station may determine the demodulator configuration for the UE to use based on one or more uplink signals transmitted from the UE. Additionally, the UE may transmit an indication of demodulator capabilities that the UE supports to the base station, where the base station determines the demodulator configuration based on the indication of the demodulator capabilities. In some examples, the demodulator configuration may indicate a demodulation search space corresponding to a number of layers included per layer group of the multi-layer transmission, may correspond to an amount of cross correlation determined between respective layers of the multi-layer transmission, or a combination thereof.
