Semi-Static Grant Activation via DL Decoding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face inefficiencies in activating semi-static or periodic occasions for uplink (UL) or downlink (DL) communications, leading to resource wastage due to unnecessary reservation of resources for low-priority and delay-insensitive UL traffic, even when no DL data is sent.
Innovation Solution
Implementing a method where semi-static or periodic occasions for UL or DL communications are activated based on the detection and successful decoding of DL transmissions, allowing for dynamic re-allocation of unused resources and reducing the need for explicit activation signaling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If semi-static or periodic occasions are activated for UL communication, then communication reliability is improved, but resource utilization deteriorates due to unnecessary reservation of resources
Solution Approach 1:
The patent implements dynamic activation of semi-static or periodic grant occasions based on actual DL data arrival. Instead of continuously reserving UL resources, the system activates grant occasions only when needed, transitioning from a static resource reservation approach to a dynamic one that adapts to actual traffic conditions, thereby improving resource utilization while maintaining communication reliability
Solution Approach 2:
The patent employs feedback mechanisms where the UE monitors DL data arrivals and provides feedback to the network entity. This feedback loop enables the network to activate or deactivate grant occasions based on actual communication needs, allowing the system to adjust resource allocation dynamically and avoid wasting resources on unnecessary UL transmissions
2Measurement precision
If explicit activation signaling is used, then activation precision is improved, but device complexity increases due to additional signaling overhead
Solution Approach 1:
The patent enables the UE to autonomously activate grant occasions based on its own monitoring of DL data arrivals, without requiring explicit activation signaling from the network. This self-service approach reduces signaling overhead and device complexity while maintaining precise activation timing, as the UE independently determines when UL resources are needed based on actual DL traffic conditions
Solution Approach 2:
The patent extracts the activation decision-making function from the network entity and places it at the UE side. By removing the need for explicit activation signaling from the network, the system simplifies the overall device complexity while maintaining precise activation control through the UE's autonomous monitoring and decision-making capabilities

AI summary
Aspects of the present disclosure relate to wireless communications, and more particularly, to mechanisms for activating semi-static or periodic occasions for communications. A method that may be performed by a user equipment (UE) includes receiving signaling configuring the UE with a set of semi-static or periodic grant occasions for communications, receiving signaling configuring at least one set of semi-static or periodic resources for downlink (DL) transmission, decoding a DL transmission on the at least one set of semi-static or periodic resources, and communicating with a network entity in grant occasions in the set of semi-static or periodic grant occasions activated based on the decoded DL transmission.
