Beam Sequence Reporting for Wireless Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face inefficiencies in beam management due to the need for frequent and periodic exchange of reference signals for channel and interference measurements, leading to increased resource utilization and overhead.
Innovation Solution
Implementing CSI reporting prediction procedures that allow User Equipment (UE) to determine and report sequences of best beams based on configured measurements, reducing the frequency of beam-related measurements and enabling the Radio Access Network (RAN) to optimize CSI Reference Signal resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If frequent and periodic exchange of reference signals is performed for beam management, then beam quality and channel measurement accuracy are improved, but resource utilization and system overhead increase
Solution Approach 1:
The system performs preliminary beam quality measurements and stores results in a buffer. Instead of performing frequent measurements, the UE retrieves previously measured beam quality information from the buffer when needed for CSI reporting, thereby reducing the frequency of actual measurements while maintaining accurate beam quality assessment.
Solution Approach 2:
The system discards redundant reference signal exchanges by utilizing stored beam quality information from the buffer. When channel conditions are stable, the UE recovers and reuses previously measured beam quality data rather than performing new measurements, reducing resource consumption while maintaining measurement accuracy.
2Measurement precision
If frequent beam-related measurements are performed, then channel and interference measurement accuracy are improved, but measurement overhead and processing complexity increase
Solution Approach 1:
Beam quality measurements are performed preliminarily and stored in advance in a buffer structure. This allows the system to have measurement results ready before they are needed for CSI reporting, eliminating the need for frequent repeated measurements and reducing measurement overhead and processing time.
3Reliability
If periodic reference signal exchange is maintained for beam management, then beam tracking accuracy is improved, but resource consumption and network overhead increase
Solution Approach 1:
The system discards redundant periodic reference signal exchanges by recovering and reusing stored beam quality information from the buffer when channel conditions are stable. This maintains reliable beam tracking while significantly reducing resource consumption and energy usage in the network.

AI summary
Apparatuses, methods, and systems are disclosed for Channel State Information (“CSC”) reporting. One apparatus includes a transceiver that receives a configuration from a radio access network (“RAN”) to report a sequence of beams that are applicable for wireless communication, and a processor that that performs beam quality measurements on resources configured by the RAN. The processor determines a sequence of beams based on the measurements and the transceiver reports the sequence of beams to the RAN, where the sequence of beams contains a series of best beams for a period of time.
