Abstract

There is disclosed a method for operating a network node in a wireless communication network. The method comprises obtaining a first precoder and/or first beam pattern indication, and a second precoder and/or second beam pattern indication, the first precoder and/or first beam pattern indication being associated to beamformed transmission of first signaling utilizing a first antenna subarray, and the second precoder and/or second beam pattern indication being associated to beamformed transmission of second signaling utilizing a second antenna subarray. A first phase center is associated to the first signaling and a second phase center is associated to the second signaling, the first phase center and the second phase center having a phase center difference. The method further comprises transmitting the first signaling on a first expanded antenna subarray utilising a first expanded precoder, and transmitting the second signaling on a second expanded antenna subarray utilising a second expanded precoder. A first expanded phase center is associated to the 15 transmitted first signaling, and a second expanded phase center is associated to the transmitted second signaling, the first expa…
