The mapping is dependent on an estimated rank for the channel and/or a layer order. The method further comprises sending (2903), to the base station, the CSI report and a rank indication for the estimated rank."
The patent application was internationally filed on Oct. 25, 2023, under International application No.PCT/SE2023/051052.
