Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may update a noise estimation (e.g., a noise covariance matrix, a log likelihood ratio (LLR) scaling, or both) for communications with a serving base station to account for interference from a neighboring base station operating according to a different radio access technology (RAT). For example, the UE may identify a transmission status of a base station operating according to a first RAT, such as long term evolution (LTE), that shares a radio frequency spectrum with a serving base station operating according to a second RAT, such as new radio (NR). The UE may measure the interference from the LTE base station and may update a noise estimation according to the measured interference. The UE and the serving base station may communicate based on the updated noise estimation.
