Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication technologies face challenges in efficiently managing UE capabilities and resource allocation, particularly in next-generation radio technologies, due to the lack of standardized methods for UE capability identification and dynamic resource management, leading to suboptimal performance and inefficiencies in handling diverse traffic types and priority signals.
Innovation Solution
Implementing a capability identifier (ID) system for user equipment (UE) that allows for dynamic resource allocation and priority handling through DCI formats, enabling flexible UE capability reporting, compression, and synchronization signal management, along with DCI-based skipping of measurement gaps for higher priority signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If measurement gaps are performed for synchronization signal reception, then synchronization accuracy is improved, but time resource utilization deteriorates
Solution Approach 1:
The patent implements dynamic measurement gap skipping where the UE selectively performs or skips measurement gaps based on DCI indications and signal priority. The measurement gap configuration is dynamically adjusted rather than fixed, allowing the system to adapt measurement timing to current traffic conditions and signal priorities, thus reducing unnecessary time resource loss while maintaining synchronization accuracy when needed.
Solution Approach 2:
The patent changes the parameter of measurement gap presence/absence based on DCI format indications. The network can dynamically signal whether measurement gaps should be performed or skipped, changing the operational parameter of the measurement process adaptively. This allows optimization of time resource utilization by skipping gaps when high-priority traffic requires continuous resource usage.
2Adaptability or versatility
If UE capability identification is standardized, then device compatibility is improved, but system complexity increases
Solution Approach 1:
The patent segments UE capability identification into multiple DCI format types (first DCI format for initial access, second DCI format for connected mode). Each DCI format contains capability information segmented into different fields and structures appropriate for its specific use case. This segmentation allows standardized capability identification without requiring a single complex unified structure, reducing overall system complexity while maintaining device compatibility.
Solution Approach 2:
The patent creates a universal DCI-based capability identification mechanism that serves multiple functions: initial access capability reporting, connected mode capability updates, and dynamic capability indication. This multi-functional approach eliminates the need for separate standardized procedures for different UE states, reducing system complexity while improving device compatibility across all operational modes.
3Productivity
If dynamic resource allocation is implemented, then resource utilization efficiency is improved, but control signaling overhead increases
Solution Approach 1:
The patent merges capability identification, resource allocation, and measurement gap control into a single DCI message structure. The DCI format combines multiple functions including UE capability indication fields, resource allocation fields, and measurement gap skipping indications. This merging reduces control signaling overhead by transmitting multiple control functions in one message rather than requiring separate signaling for each function, thus improving resource utilization efficiency without proportionally increasing overhead.
Solution Approach 2:
The patent implements partial capability reporting where only relevant UE capability fields are included in DCI based on current operational needs. The DCI format includes optional capability fields that are only transmitted when necessary, avoiding excessive signaling overhead. This partial action approach maintains dynamic resource allocation efficiency while keeping control signaling overhead proportional to actual requirements rather than always transmitting complete capability sets.
Data Source
AI summary
A method performed by a user equipment (UE) may comprise receiving a first synchronization signal, from a base station, and decoding PBCH by way of the first synchronization signal and receiving RRC information, from the base station, wherein the RRC information indicates information about a second synchronization signal which is different from the first synchronization signal. The method may further comprise determining a periodicity of the second synchronization signal based on the RRC information and receiving, on a secondary cell (SCELL) of the base station, the second synchronization signal in accordance with the periodicity. The UE may receive a measurement gap configuration and first downlink control information (DCI) that schedules resources over more than one set of frequency domain resources. The UE may skip at least one measurement gap due at least in part to a higher priority signal in accordance with an offset from the first DCI.
