Sidelink SR Configuration for Multi-Unicast CSI Triggering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In sidelink communication, there is a challenge in correctly triggering a scheduling request (SR) process for multiple unicast connections due to the lack of clear configuration between channel state information (CSI) reports and SR configurations.
Innovation Solution
A method and system for configuring scheduling requests (SRs) that involve mapping multiple unicast connections to one or multiple SR configurations and corresponding SR counters, allowing for accurate triggering of SRs based on CSI reports.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple unicast connections are supported in sidelink communication, then communication versatility is improved, but SR triggering accuracy deteriorates due to lack of clear configuration between CSI reports and SR configurations
Solution Approach 1:
The patent segments the SR configuration by introducing SR counters that are separately maintained for each unicast connection. This segmentation allows the system to support multiple unicast connections while maintaining accurate SR triggering for each individual connection, resolving the contradiction between versatility and precision.
Solution Approach 2:
The patent introduces configuration information as an intermediary element that explicitly maps CSI reports to SR configurations and SR counters. This intermediary configuration information establishes clear correspondence relationships, enabling accurate SR triggering while supporting multiple unicast connections.
2Device complexity
If SR configuration is simplified for multiple unicast connections, then device complexity is reduced, but SR triggering reliability deteriorates
Solution Approach 1:
The patent creates a universal SR configuration framework that can handle multiple unicast connections through a standardized configuration information structure. This universal approach maintains reliability by consistently applying the same configuration principles across all connections while avoiding the need for complex connection-specific configurations.
Solution Approach 2:
The patent changes the configuration parameters by introducing SR counters as a new parameter that tracks SR transmissions per unicast connection. This parameter change enables reliable SR triggering by providing explicit state information without significantly increasing overall configuration complexity.
3Measurement precision
If SR counters are maintained for each unicast connection, then SR triggering accuracy is improved, but power consumption increases
Solution Approach 1:
The patent performs preliminary action by configuring SR counters and their correspondence relationships in advance through configuration information. This preliminary configuration allows the terminal to efficiently manage SR triggering for multiple connections without continuous complex processing, thereby improving accuracy while controlling power consumption.

AI summary
Embodiments of the present disclosure provide a scheduling request configuration method, a terminal, and a network device, and relate to the field of communication technologies. The scheduling request configuration method includes: receiving configuration information from a network device, where the configuration information includes that CSI reports of multiple unicast connections of the terminal correspond to one SR configuration, and the one SR configuration corresponds to one or more SR counters; and/or, the configuration information includes that the CSI reports of the multiple unicast connections of the terminal correspond to multiple SR configurations, and the multiple SR configurations correspond to multiple SR counters.
