Multi-Interface Grant Skipping for Wireless Resource Collisions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems lack efficient methods for indicating and utilizing skipped communication resources across multiple interfaces and component carriers, leading to suboptimal resource utilization.
Innovation Solution
A user equipment (UE) receives configured grants for both sidelink and access link communications and determines to skip certain communication occasions, transmitting indications of these skipped resources to network entities or other UEs, allowing for more efficient resource utilization through separate or combined indications based on events like collisions, power management, and measurement gaps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the UE transmits separate indications for each interface's skipped resources, then the resource utilization efficiency is improved, but the signaling overhead and system complexity increase
Solution Approach 1:
The patent combines multiple separate indications of skipped resources across different interfaces (sidelink and access link) into a single unified indication transmitted by the UE to the network entity. This single indication efficiently conveys resource skipping information for multiple interfaces simultaneously, improving resource utilization while avoiding the overhead of multiple separate signaling transmissions.
2Reliability
If the UE monitors all configured communication occasions across multiple interfaces, then the communication reliability is improved, but the power consumption and processing load increase
Solution Approach 1:
The patent enables dynamic resource skipping where the UE can selectively skip monitoring and transmission in certain communication occasions based on current system conditions, data availability, and priority requirements. This dynamic approach allows the UE to adapt its monitoring behavior to actual needs, reducing power consumption and processing load while maintaining communication reliability for high-priority transmissions.
Solution Approach 2:
The patent extracts and identifies specific communication occasions that can be safely skipped from the full set of configured occasions. By analyzing which occasions are redundant or low-priority, the system removes unnecessary monitoring and transmission activities, thereby reducing power consumption and processing requirements while preserving essential communication functions.
3Measurement precision
If the UE transmits indications of skipped resources frequently, then the resource allocation accuracy is improved, but the signaling overhead increases
Solution Approach 1:
The patent implements partial indication where the UE transmits skipped resource indication information selectively rather than for every single skipped occasion. The indication may cover multiple skipped occasions in a single transmission or only indicate skipped resources above certain thresholds, thereby achieving sufficient resource allocation accuracy while significantly reducing signaling overhead compared to indicating every skipped resource individually.

AI summary
Methods, systems, and devices for wireless communications are described. A first UE may receive a first configuration of a first configured grant indicating a first set of resources for a first interface between the UE and a second UE, and may receive a second configuration of a second configured grant indicating a second set of resources for a second interface between the UE and a network entity. The UE may determine to skip one or more communication occasions of the first set of resources, the second set of resources, or both. The UE may transmit, to a communication device including the second UE, the network entity, or both, an indication of the one or more communication occasions that are skipped.
