Abstract
Methods, a user equipment and a radio network node relating to estimation of a channel quality indicator, CQI, are provided. A first reference signal is carried by a downlink channel of a radio communication system. The user equipment receives from the radio network node information about scheduling of a downlink transmission to the user equipment and information about a second reference signal being different from the first reference signal. Furthermore, the user equipment receives from the radio network node the downlink transmission. The downlink transmission comprises the first reference signal and the second reference signal. Next, the user equipment estimates the CQI based on the first reference signal and the second reference signal.
