Abstract
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a demodulation reference signal (DMRS) and perform a filtering procedure on frequency-domain symbols of the DMRS to obtain a frequency-domain noise signal associated with the frequency-domain symbols. The UE may perform a spur detection procedure on the frequency-domain noise signal to detect one or more frequency spurs associated with the frequency-domain symbols. In addition, the UE may estimate a frequency of the frequency spurs. In some implementations, the UE may transmit information indicating spur parameters associated with the frequency spurs (e.g., including the estimated frequency) to a network entity. The UE may receive a control message indicating a rate matching pattern for subsequent communications, the rate matching pattern based on the spur parameters. The UE and the network entity may communicate according to the rate matching pattern.
