Abstract: An integrated terrestrial/non-terrestrial network may allow for enhanced network coverage. However, there are control and management challenges associated with an integrated terrestrial/non-terrestrial network because the network and user equipments (UEs) are no longer confined to only using conventional cellular communication via terrestrial transmit-and-receive points (T-TRPs). One challenge is how to perform beam management. In some embodiments, methods and systems are disclosed in which an indication of angular direction (e.g. beam direction) is provided by the T-TRP. The indication of angular direction may be used by a UE for communicating with a non-terrestrial TRP (NT-TRP), e.g. using beamforming. However, the methods are not limited to integrated terrestrial/non-terrestrial networks or the involvement of NT-TRPs, but apply more generally to indicating angular direction for directional communication.

Abstract: An apparatus and a method for configuring antenna arrays for scalable radio frequency (RF) architecture are dis-closed. A subset of antenna arrays are grouped into K groups and a receive or transmit weight vector is applied to each of the antenna arrays in each of the K groups. A channel response is measured for each of the antenna in the K groups. The response is summed for each group and complex scaling factors are calculated based on the summed response. Based on the scaling factors the antenna weight vectors arc updated and the updated weight vectors arc applied to the antenna arrays. The steps of grouping the antennas and refining the weight vectors are performed till the antenna weight vectors reach a steady point, i.e. the current antenna weight does not improve the beamforming gain by a predetermined threshold in comparison to the previous antenna weight.
