Beam Measurement Reporting for Candidate Cell Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The frequent reporting of beam measurement results by terminal devices for all candidate cells consumes excessive energy and occupies more uplink resources, which is not conducive to energy saving and resource efficiency.
Innovation Solution
The terminal device selectively reports the beam measurement result of a specific candidate cell determined from a set of candidate cells, reducing unnecessary reporting and conserving power and resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the terminal device reports beam measurement results of all candidate cells frequently, then the network device can obtain comprehensive network state information, but the terminal device consumes excessive energy and occupies more uplink resources
Solution Approach 1:
The patent extracts only the necessary beam measurement results from all candidate cells by determining a specific candidate cell based on predefined conditions (such as reference signal received power thresholds or beam quality metrics). This selective extraction approach provides the network device with sufficient information for switching decisions while eliminating unnecessary frequent reporting of all candidate cells, thereby reducing terminal device energy consumption.
Solution Approach 2:
Instead of reporting beam measurement results of all candidate cells (excessive action), the patent applies partial action by reporting only the beam measurement result of the specific candidate cell that meets the determination conditions. This partial reporting strategy maintains effective network state awareness while significantly reducing the frequency and volume of uplink transmissions.
2Reliability
If the terminal device reports beam measurement results of all candidate cells frequently, then the network device can make accurate switching decisions, but more uplink resources are occupied
Solution Approach 1:
The patent extracts only the essential beam measurement information needed for switching decisions by identifying a specific candidate cell that meets predetermined conditions. This selective extraction ensures that the network device receives sufficient information for accurate switching decisions while reducing the quantity of uplink resources consumed by eliminating redundant reports of all candidate cells.
Solution Approach 2:
The patent changes the reporting parameter from comprehensive reporting of all candidate cells to selective reporting based on specific determination conditions. By adjusting the reporting criteria to focus on candidate cells that meet certain thresholds (such as reference signal received power or beam quality), the system maintains decision accuracy while optimizing uplink resource utilization.
