Zusammenfassung:Optimizing transmission powers of antenna arrays in base stations by using feedback signals from multiple wireless communication devices. A method performed by the base stations includes identifying a first served wireless communication device and a second served wireless communication device; transmitting a first signal to the first served wireless communication device via the antenna array with a first initial set of phase values and a second signal to the second served wireless communication device via the antenna array with a second initial set of phase values; receiving a first measurement of the first signal from the first served wireless communication device and a second measurement of the second signal from the second served wireless communication device; and performing a calibration procedure based on the first measurement to provide a first calibrated set of phase values and the second measurement to provide a second calibrated set of phase values.
