Network-Side Virtual Cell Assignment for Dynamic 6G Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication mechanisms, particularly in 6G systems, struggle to support flexible and dynamic cell coverage, especially in scenarios involving high mobility and high throughput data transmission with low latency and high reliability, such as Industrial Internet of Things (IIoT), Metaverse, and vehicle wireless communication, due to challenges in cell handover and frequency reuse.
Innovation Solution
A network side device determines a virtual cell or a target TRP set for a terminal based on obtained first information, which can be unique identifier information or an access request sequence carried by a reference signal, allowing for semi-static or dynamic configuration of dedicated TRP sets to support flexible cell coverage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If pre-planned cell transmission resource and coverage area are used, then network structure is simple and easy to manage, but the system cannot support flexible and dynamic cell coverage required for high mobility scenarios
Solution Approach 1:
The patent implements dynamic cell coverage by allowing TRP sets to be configured semi-statically or dynamically based on terminal mobility states. The network can adjust the TRP set serving a terminal according to real-time channel conditions and mobility requirements, transforming fixed cell transmission into mobile cell transmission. This resolves the contradiction by making the coverage area adaptable without requiring complete reconfiguration of the network structure.
Solution Approach 2:
The patent divides the coverage area into multiple TRPs (Transmission Reception Points) that can be selectively activated. Instead of treating cell coverage as a single fixed entity, the system segments it into multiple TRPs that can be dynamically assigned to terminals based on their mobility states and channel conditions, enabling flexible coverage adjustment while maintaining manageable network structure.
2Speed
If traditional cell handover mechanism is used, then handover procedure is simple, but it cannot support high mobility speed and high throughput data transmission with low latency
Solution Approach 1:
The patent performs preliminary actions by pre-configuring multiple TRP sets for terminals before handover is needed. When a terminal enters a high mobility state, the network has already prepared alternative TRP sets that can be quickly activated. This eliminates the need for traditional handover procedures, enabling seamless transition between TRPs without interrupting high throughput data transmission, thus supporting both high mobility speed and handover reliability.
3Productivity
If fixed cell transmission is used, then network management is straightforward, but it cannot achieve high throughput and low latency for edge terminals and handover scenarios
Solution Approach 1:
The patent implements self-service mechanisms where terminals autonomously detect their mobility states and channel conditions, then report this information to the network. The network uses this feedback to automatically adjust TRP set assignments without requiring manual intervention. This enables high throughput and low latency for edge terminals while keeping network management relatively simple through automated decision-making based on terminal-reported conditions.
4Adaptability or versatility
If dynamic TRP set configuration is implemented, then flexible cell coverage is achieved, but signaling overhead and system complexity increase
Solution Approach 1:
The patent changes key parameters such as terminal mobility state, channel quality indicators, and TRP set configurations to enable dynamic coverage adjustment. By monitoring and adjusting these parameters based on terminal conditions, the system achieves flexible cell coverage while minimizing signaling overhead through efficient parameter reporting and update mechanisms rather than extensive reconfiguration messages.
