Abstract
A method and apparatus are provided. The method includes receiving, by a user equipment (UE), a first signal from a transceiver, determining one of a probability and a soft mean with a soft variance associated with the detected data symbol, determining a first coefficient and a second coefficient based on the determined one of the probability and the soft mean with the soft variance associated with the detected data symbol, determining channel state information (CSI) on a channel between the transceiver and the UE based on a second signal received by the UE from the transceiver, a previous CSI, the first coefficient and the second coefficient, and tracking the communication channel based on the determined CSI.
