Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may measure a first energy level of a demodulation reference signal (DMRS). The UE may measure a second energy level of at least one of a tracking reference signal (TRS) or a synchronization signal block (SSB). The UE may determine, based at least in part on the first energy level and the second energy level, a DMRS signal-to-noise ratio (SNR). The UE may perform, based at least in part on the DMRS SNR, channel estimation for a physical channel associated with a communication to determine an estimated channel. The UE may perform, based at least in part on the estimated channel, demodulation processing for the communication. Numerous other aspects are described.
