Beam Sweeping During Loop Processing in Wireless Communications
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems like 5G NR, user equipment (UE) faces challenges in power efficiency due to the inability to perform beam sweeping during synchronization signal burst set (SSBS) processing, limiting sleep duration and impacting connected discontinuous receive (CDRX) configurations.
Innovation Solution
The UE uses signals within the SSBS for both loop processing and beam sweeping, allowing it to apply serving and non-serving beams on different symbols, thereby reducing the need for independent beam sweeping procedures and increasing sleep duration, which conserves power.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the UE performs independent beam sweeping procedures separate from loop processing, then beam coverage and mobility tracking are improved, but power consumption increases and sleep duration decreases
Solution Approach 1:
The patent combines beam sweeping operations with loop processing operations into a unified procedure. The UE processes synchronization signals for both beam sweeping and loop processing simultaneously during the same time resources, rather than performing separate independent procedures. This merging eliminates redundant processing and allows the UE to maintain beam coverage and mobility tracking capabilities while reducing power consumption and enabling longer sleep durations.
2Reliability
If the UE performs independent beam sweeping procedures, then mobility tracking performance is improved, but sleep duration is reduced
Solution Approach 1:
The patent merges beam sweeping and loop processing into a single unified operation that occurs during the same time resources. By processing synchronization signals for both purposes simultaneously, the UE achieves mobility tracking performance without requiring separate dedicated time for beam sweeping, thereby preserving sleep duration and enabling more extended low-power states.
3Measurement precision
If the UE uses dedicated time for beam sweeping, then beam sweeping accuracy is improved, but productivity of other processing tasks decreases
Solution Approach 1:
The patent combines beam sweeping and loop processing into a unified procedure that operates simultaneously during the same time resources. This approach maintains beam sweeping accuracy by processing synchronization signals with dedicated attention, while also performing loop processing tasks in parallel, thereby improving overall processing efficiency and productivity without sacrificing measurement precision.
Solution Approach 2:
The patent enables continuous useful action by performing both beam sweeping and loop processing simultaneously during the same time resources rather than sequentially. This continuous dual-purpose processing ensures that beam sweeping accuracy is maintained while maximizing the utilization of available time resources, thereby improving the productivity of overall system operations.
