Common Component Carrier Configuration for Reliable Sidelink Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in configuring component carriers for sidelink communications, as UEs may not be configured with a common component carrier, leading to inefficiencies and increased signaling overhead.
Innovation Solution
A method for determining and configuring a common component carrier between UEs for sidelink communications, involving control signaling and message exchange to identify and utilize component carriers supported by both UEs, facilitated by base stations or anchor UEs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If UEs are configured with different component carriers for sidelink communications, then each UE can use its own optimized carriers, but communication reliability deteriorates because no common carrier is available
Solution Approach 1:
The patent designates one component carrier as a common carrier that both UEs can use for sidelink communications. This common carrier serves as a universal interface between UEs with different carrier configurations, enabling reliable communication while preserving the ability of each UE to use its own optimized carriers for other purposes.
2Reliability
If a common component carrier is configured for both UEs, then communication reliability improves, but signaling overhead increases due to additional configuration messages
Solution Approach 1:
The network configures the common component carrier between UEs before sidelink communication is needed. This preliminary configuration ensures that when sidelink communication is required, both UEs already have a ready-to-use common carrier, avoiding the need for time-consuming carrier negotiation and reducing signaling overhead during actual communication.
3Productivity
If carrier aggregation is implemented for sidelink communications, then communication capacity increases, but device complexity increases due to multiple carrier management
Solution Approach 1:
The patent segments carrier usage into two distinct parts: a common component carrier for reliable sidelink communication between UEs, and UE-specific component carriers for optimized performance. This segmentation allows carrier aggregation to increase capacity while simplifying management by clearly defining the role of each carrier type.

AI summary
Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may receive control signaling indicating a set of component carriers allocated for sidelink communications performed by the first UE. The first UE may receive a message indicating a subset of component carriers from the set of component carriers for use in communicating via a sidelink between the first UE and a second UE, where the subset of component carriers may be supported by the first UE and the second UE. In some cases, a base station or anchor UE may determine or configure the subset of component carriers for use between the first and second UEs. In some cases, the first UE, the second UE, or a both may determine the subset of component carriers. The first UE may communicate with the second UE via a component carrier from the subset of component carriers.
