Shared Transceiver Chains for Reliable Multi-Connection UEs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multi-connection user devices sharing a transmitter/receiver chain with two or more connections experience issues such as data loss, delay, and service interruptions due to overlapping operation occasions and unexpected tuning away from current connections, leading to resource wastage and errors in the network.
Innovation Solution
The user device signals information about operation occasions of other connections to the network entity, and when tuning away, sends a tune away signal (TAS) to manage shared transceiver chain usage, ensuring network entities are aware of UE availability and operation clashes, thereby avoiding collisions and interruptions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a UE shares a transceiver chain with multiple connections, then device complexity is reduced, but data loss and service interruptions occur due to overlapping operation occasions
Solution Approach 1:
The network entity determines unavailable periods for the UE based on operation occasions of other connections before scheduling transmissions. This preliminary identification of conflict periods allows the network to avoid scheduling data transmissions during times when the UE must tune away to other connections, preventing data loss and service interruptions while maintaining the shared transceiver chain configuration
Solution Approach 2:
The system implements feedback mechanisms where the UE reports operation occasions of other connections to the network entity. This feedback loop enables the network entity to adjust scheduling decisions dynamically, ensuring that transmissions are scheduled only during periods when the UE is available, thus resolving the reliability issue without requiring separate transceiver chains
2Productivity
If the UE performs operations on multiple connections simultaneously, then communication efficiency is improved, but collisions and service interruptions occur due to transceiver chain conflicts
Solution Approach 1:
The network entity performs preliminary scheduling by determining unavailable periods based on reported operation occasions before actual data transmissions. This advance planning ensures that high-speed communications on multiple connections can proceed without collisions, as the network proactively avoids scheduling conflicts rather than reacting to them after they occur
Solution Approach 2:
The scheduling system dynamically adapts to the UE's operational state by continuously receiving updates about operation occasions of other connections. The network entity adjusts transmission schedules in real-time based on this dynamic information, allowing the system to maintain high communication efficiency while avoiding collisions through flexible, adaptive resource allocation
3Adaptability or versatility
If the UE tunes away from current connection to perform operations on other connections, then multi-connection functionality is enabled, but unexpected network behavior and errors occur
Solution Approach 1:
The UE reports operation occasions of other connections to the network entity in advance. This preliminary information sharing allows the network entity to anticipate when the UE will tune away from the current connection and adjust scheduling accordingly, enabling multi-connection functionality while preventing unexpected network behavior through proactive coordination
Solution Approach 2:
The system establishes continuous feedback communication where the UE informs the network about its operational status on multiple connections. This feedback mechanism ensures that the network remains aware of when the UE is tuning away to other connections, maintaining network operation stability through informed decision-making while preserving the UE's multi-connection versatility

AI summary
A user device, UE, for one or more wireless communication systems, includes one or more transceiver chains. The UE shares at least one transceiver chain with at least two connections to the one or more wireless communication systems. The UE is connected to one or more network entities, like a gNB or another UE, with the connections, and perform one or more operations on the connections at respective operation occasions. When the UE transmits or receives on a current one of the connections, it does not to transmit or receive on the other connections.
