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.

Techniques for demodulation reference signal based signal-to-noise ratio for demodulation processing

Provided are an apparatus and method for pre-coding data based on quantized channel state information and channel statistics. In use, channel statistics are collected. Further, one or more reference signals are sent to a wireless device via at least one channel. Thereafter, quantized channel state information is received that corresponds to the at least one channel, where the quantized channel state information is sent by the wireless device based on the one or more reference signals. Data is pre-coded based on the quantized channel state information and the channel statistics. Further, the pre-coded data is transmitted to the wireless device.
