Reference Signal Resource Sets for Beam Sweeping Capability Limits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Terminal devices are unable to support the full number of beams configured by the network due to capability limitations, leading to challenges in determining all beams configured by the network device during beam sweeping.
Innovation Solution
A method where a network element configures and indicates reference signal resources to a terminal device, allowing the terminal device to determine a reference signal resource set group, even if the total resources exceed its capability, by associating multiple sets of resources to overcome the limitation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the network device configures a large quantity of beams for terminal device, then the beam coverage and signal concentration are improved, but the terminal device capability is exceeded and cannot support sweeping all beams
Solution Approach 1:
The patent divides the large quantity of beams into multiple groups, where each group contains a subset of beams that the terminal device can sweep within its capability limit. The network device configures multiple beam groups, and the terminal device sweeps beams group by group, thereby resolving the contradiction between configuring many beams and the terminal device's sweeping capability.
2Measurement precision
If the network device configures more reference signal resources, then the measurement precision is improved, but the terminal device cannot process all resources within one configuration period
Solution Approach 1:
The patent segments the reference signal resources into multiple resource sets, where each set contains a manageable number of resources that the terminal device can process within its time limit. The network device configures multiple resource sets, and the terminal device processes them in batches, achieving both high measurement precision and acceptable processing speed.
3Area of stationary object
If the beam sweeping period is extended to cover more beams, then the coverage is improved, but the time consumption increases
Solution Approach 1:
The patent divides the beam sweeping process into multiple periods, with each period dedicated to sweeping a specific group of beams. The network device configures multiple beam groups corresponding to different time periods, allowing the terminal device to complete sweeping within each period while covering the entire cell area across all periods, thus balancing coverage and time consumption.

AI summary
A reference signal resource configuration method, including: a second apparatus (reference signal resource configuration network element) configures a first reference signal resource set for a first apparatus (reference signal resource measurement network element) based on first information. All reference signal resources configured by the second apparatus are indicated to the first apparatus based on second information. The first apparatus may determine a reference signal resource set group based on the second information. The first apparatus may learn, based on the first information and the second information, whether the first reference signal resource set is all the reference signal resources configured by the second apparatus, to learn of a status of all the reference signal resources configured by the second apparatus.
