Joint Scheduling Access Network and Sidelink Control Signaling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless communication systems have separate configurations for access links and sidelinks, leading to inefficient communications due to the lack of joint scheduling, resulting in suboptimal resource allocation and increased latency.
Innovation Solution
Implementing a method for a base station to jointly schedule user equipment (UE) resources for both access network and sidelink communications using control signaling, which includes messages that configure UEs for simultaneous access network and sidelink operations, such as sidelink grants and downlink/uplink grants within the same control messages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If separate configurations are used for access links and sidelinks, then device complexity is reduced, but communication efficiency deteriorates and resource allocation becomes suboptimal
Solution Approach 1:
The patent combines separate access link and sidelink configurations into a unified joint configuration mechanism. The network device generates a single configuration message that contains both access link configuration information and sidelink configuration information, allowing the UE to be configured for both types of communications simultaneously through one unified process rather than separate independent configurations.
2Loss of information
If separate configurations are used for access links and sidelinks, then control signaling overhead is reduced, but latency increases due to lack of coordinated resource management
Solution Approach 1:
The patent merges access link control signaling and sidelink control signaling into a single joint configuration message. The network device generates one configuration message that simultaneously configures both access link resources and sidelink resources, eliminating the need for separate configuration messages and enabling coordinated resource allocation that reduces latency.
3Productivity
If joint scheduling is implemented for access links and sidelinks, then resource allocation efficiency is improved, but device complexity increases
Solution Approach 1:
The network device acts as an intermediary that performs the complex joint scheduling calculations and resource allocation decisions. The network device generates the unified configuration message containing both access link and sidelink resource allocations, while the UE simply receives and executes this pre-computed configuration, thereby transferring the scheduling complexity from the UE to the network device.
4Use of energy by moving object
If joint scheduling is implemented for access links and sidelinks, then power consumption is reduced through coordinated resource management, but control signaling complexity increases
Solution Approach 1:
The patent combines control signaling for access links and sidelinks into a single unified configuration message. By merging the configuration processes and using a unified resource allocation mechanism, the patent reduces the total amount of control signaling required while simultaneously enabling power-saving features through coordinated resource management that allows the UE to enter sleep modes more effectively.

AI summary
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive at least one control message from a base station, the at least one message jointly scheduling the UE for access network communications between the UE and the base station and for sidelink communications between the UE and another UE, such as another UE in a group of UEs. The UE may determine network control information based on the at least one control message. The UE may also determine sidelink control information based on the at least one control message. The UE may communicate with the base station and the other UE in accordance with the network control information and the sidelink control information, respectively.
