A radio base station RBS (10) of a wireless communication network indicates to a wireless device (14, 18, 20) where in the time domain and / or frequency domain to perform radio quality measurements. If the RBS (10) determines that one or more wireless devices (14, 18, 20) (including those that are idle) are at risk of performing degraded quality measurements, it suppresses scheduling beamformed downlink data in the time / frequency region where the wireless device (14, 18, 20) performs quality measurements when a reference signal (e.g., a cell-specific reference signal or CRS) is broadcast. This avoids RSRQ degradation due to beamforming gain and allows existing legacy functions that rely on RSRQ to continue to operate as originally planned. The restriction applies only to beamformed data - the transmission of non-beamformed data in the relevant bandwidth is already taken into account when using RSRQ measurements.
