Abstract
Method and one or more first devices for supporting calibration of a multi-antenna array comprised in a first antenna device operative with a wireless communication network. The first device(s) provide phase correcting information, to be used in calibration of the multi-antenna array, based on covariances corresponding to recurrent displacement vectors of the multi-antenna array. Said covariances being based on channel estimates estimated from certain radio signals received after transmission over radio propagation channels between said multi-antenna array of the first antenna device and one or more second antenna devices operative with the wireless communication network.
