Narrowband Processor Signal Priority Scheme for Wireless UE
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication systems face challenges in efficiently measuring multiple signal types using multiple narrowband processors, which increases processing power and complexity, particularly in handling synchronization signal blocks (SSBs) across different frequency ranges and paging signals.
Innovation Solution
A user equipment (UE) identifies a priority scheme for signals, including SSB signals in different frequency ranges and a paging signal, and uses a single narrowband processor to monitor time resources based on this scheme, avoiding collisions by prioritizing signal monitoring and refraining from monitoring lower priority signals during collisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple narrowband processors are used to measure multiple signal types simultaneously, then measurement capability and reliability are improved, but processing power requirements and device complexity increase
Solution Approach 1:
The patent combines multiple narrowband processors into a single processor that sequentially processes different signal types. The single processor alternates between measuring SSB signals in FR1 and FR2, and monitoring paging signals, thereby reducing hardware complexity while maintaining measurement reliability through time-division multiplexing
Solution Approach 2:
The single narrowband processor is designed to perform multiple functions by switching between different measurement tasks. It can measure synchronization signals (SSB) in both frequency ranges and monitor paging signals sequentially, making one processor universal for multiple signal types that would traditionally require separate dedicated processors
2Productivity
If multiple narrowband processors are deployed to handle different signal types concurrently, then processing speed and productivity are improved, but manufacturing cost and device complexity increase
Solution Approach 1:
The patent merges multiple processors into one, reducing manufacturing costs associated with producing and integrating multiple narrowband processors. The single processor achieves comparable productivity by sequentially handling different signal measurements, eliminating the need for expensive multi-processor hardware configurations
3Device complexity
If a single narrowband processor is used to measure multiple signal types, then device complexity and manufacturing cost are reduced, but signal collision and measurement precision may deteriorate
Solution Approach 1:
The patent implements periodic action by alternating between different measurement tasks in a structured sequence. The processor periodically switches between measuring SSB signals in FR1, measuring SSB signals in FR2, and monitoring paging signals, ensuring each signal type receives dedicated processing attention at regular intervals, thereby maintaining measurement precision while using a single processor
Solution Approach 2:
The patent applies preliminary action by determining a priority scheme and measurement sequence before actual signal processing begins. The UE identifies which signals have higher priority and pre-plans the measurement schedule, ensuring that when signal collisions are detected, the processor can immediately switch to the appropriate higher-priority signal without compromising measurement accuracy
4Reliability
If the UE monitors all signal types simultaneously with a single processor, then measurement completeness is improved, but signal collision and processing efficiency worsen
Solution Approach 1:
The patent applies preliminary action by establishing a priority scheme that ranks different signal types (SSB in FR1, SSB in FR2, paging signals) before measurement begins. This pre-planned priority structure enables the processor to efficiently determine which signals to measure first and which to skip when collisions occur, maintaining detection completeness for high-priority signals while improving processing efficiency by avoiding redundant or lower-priority measurements

AI summary
Methods, systems, and devices for wireless communications are described. The method may include a user equipment (UE) identifying a priority scheme for a set of signals including a first set of synchronization signal block (SSB) signals associated with a first frequency range, a second set of SSB signals associated with a second frequency range, and a paging signal associated with the first frequency range. The UE may then monitor, via a narrowband processor of the UE and based on the priority scheme, a set of time resources for one or more of the first set of SSB signals, the second set of SSB signals, or the paging signal. The narrowband processor may be configured to process signals received via the first frequency range and the second frequency range.
