MULTI-RESOLUTION CSI FEEDBACK - A simplified explanation of the abstract
This abstract first appeared for US patent application 18355044 titled 'MULTI-RESOLUTION CSI FEEDBACK
Simplified Explanation
The abstract describes a method performed by a radio device for Channel State Information (CSI) feedback in a communication system.
- The method involves receiving information about a CSI Reference Signal (RS) resource, a first CSI type, and a second CSI type for feedback from a Radio Access Network (RAN) node.
- The radio device also receives a CSI feedback request from the RAN node for measuring and providing feedback on either the first CSI type or the second CSI type.
- The radio device measures the CSI of the indicated type based on signals received on the CSI-RS resource.
- Finally, the radio device sends a CSI report of the requested CSI type back to the RAN node.
Key points:
- The method focuses on providing Channel State Information (CSI) feedback in a communication system.
- It involves receiving information about CSI Reference Signal (RS) resource and different types of CSI for feedback.
- The method includes measuring the requested CSI type based on signals received on the CSI-RS resource.
- The radio device then sends a CSI report of the requested type back to the Radio Access Network (RAN) node.
Original Abstract Submitted
A method performed by a radio device for Channel State Information (CSI) feedback in a communication system comprising a Radio Access Network (RAN) node comprises receiving, from the RAN node, information about a CSI Reference Signal (RS) resource, a first CSI type and a second CSI type for feedback. The method also comprises receiving, from the RAN node, a CSI feedback request for CSI measurement and feedback of the first CSI type or the second CSI type. The method also comprises measuring CSI of the indicated type based on signals received on the CSI-RS resource. The method also comprises sending, to the RAN node, a CSI report of the requested CSI type. A corresponding method in a RAN node is furthermore presented herein.
