Abstract
Radio alignment of downlink and uplink channels between a wireless device and a multi-antenna base station. A method performed by a network node comprises obtaining downlink channel data, wherein the downlink channel data comprises: estimates of a plurality of downlink channels each associated with a downlink reference signal being received from one of the antennas at the wireless device, and time synchronization information associated with each of the downlink channels; obtaining uplink channel data, wherein the uplink channel data comprises: estimates of a plurality of uplink channels each associated with an uplink reference signal being received at one of the antennas from the wireless device, and time synchronization information associated with each of the uplink channels; comparing the downlink channel data and the uplink channel data to determine whether the downlink channel and uplink channel between the wireless device and the multi-antenna base station are aligned.
