Patent number: 11483035Abstract: Disclosed are methods and apparatuses for performing precoding. A method disclosed comprises steps of: transmitting a CSI reference signal to a UE to request the UE to report status-related information of respective panels; acquiring, based on first feedback information from the UE, the status-related information of the respective panels whose status-related information has been measured by the UE and a serving panel selected by the UE; and performing, based on the status-related information of the respective panels and the serving panel selected by the UE, two-stage beamforming separately to the respective panels, so as to first perform decoupling to suppress inter-panel interference and then perform per-panel precoding. The disclosure offers the following advantages: effectively eliminating the inter-panel and intra-panel interference, avoiding complex inter-panel calibration, and reducing implementation complexity and CSI feedback overhead.Type: GrantFiled: November 23, 2018Date of Patent: October 25, 2022Assignee: Nokia Shanghai Bell Co., Ltd.Inventors: Nuan Song, Huan Sun, Tao Yang
