Abstract
A radio base station, RBS (10) of a wireless communication network indicates to a wireless device (14, 18, 20) where in the time 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 in risk of performing deteriorated quality measurements, it refrains from scheduling beamformed downlink data in the time/frequency region where the wireless devices (14, 18, 20) perform quality measurements when the reference signals (e.g., Cell Specific Reference Signals, or CRS) are broadcast. This avoids deterioration of the RSRQ due to beamforming gain, and allows existing legacy features that rely on RSRQ to continue to function as originally intended. The restriction is only on beamformed data—the transmission of non-beamformed data in the relevant bandwidth is already accounted for in the use of RSRQ measurements.
