Problems solved by technology
This beam scanning process can be expensive in terms of time consumption and overhead signaling when there are many candidate beams at both the TRP and the wireless device
Also, in some scenarios, a wireless device may be operatively connected to different TRPs in downlink and uplink, thus this may require separate beam management procedures for downlink and uplink

There is provided mechanisms for determining an electrical phase relation between antenna elements in an antenna array. A method is performed by a radio transceiver device. The method comprises obtaining measurements of the radio signal as received in two receive beams covering a given angular sector. The receive beams have different complex beam patterns. The method comprises estimating the angleof arrival of the radio signal for at least one polarization port of each of the receive beams using the measurements in the two receive beams. The method comprises determining, from the angle of arrival estimated for each polarization port, an electrical phase relation between antenna elements in the antenna array that corresponds to the estimated angle of arrival.
Description
technical field [0001] Embodiments presented herein relate to methods, radio transceiver arrangements, computer programs and computer program products for determining electrical phase relationships between antenna elements in an antenna array. Background technique [0002] In a communication network, for a given communication protocol, its parameters, and the physical environment in which the communication network is deployed, challenges may exist in obtaining good performance and capacity. [0003] For example, frequency bands at many different carrier frequencies may be required for future generations of mobile communication systems. For example, such low frequency bands may be required to achieve adequate network coverage for wireless devices, and higher frequency bands (e.g., at millimeter wavelength (mmW), ie, near and above 30 GHz) may be required to achieve all required network capacity. In general, at high frequencies the propagation characteristics of the radio ch...
