Method for CSI feedback

摘要: Embodiments of systems and methods for flexible Channel State Information (CSI) feedback in a cellular communications network are disclosed. In some embodiments, base station configures wireless device with set CSI-RS resources, dynamically resource from the resources measurement, receives CSI report determined configured measurement. this manner, is enabled to configure re-configure resource(s) measurement by device, which turn provides that particularly well-suited embodiments transmits beamformed CSI-RS.
