Abstract
A method performed by a wireless device for enabling a determination of a reference signal configuration for downlink transmissions in a wireless communications network is provided. The wireless device obtains information indicating the number of used transform coefficients of the total number of transform coefficients determined in a transform-based channel estimator in the wireless device upon receiving a first downlink transmission according to a first reference signal configuration. Also, the wireless device determines, based on the obtained information, if the first reference signal configuration for downlink transmissions to the wireless device is to be modified or not. A wireless device for enabling a determination of a reference signal configuration for downlink transmissions in a wireless communications network is also provided. Further, a network node and method therein for determining a reference signal configuration for transmissions in a wireless communications network are provided.
