Multi-BWP Terminal Operation for Unicast and Groupcast Traffic
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional communication systems in NR limit terminal devices to operate on a single BWP, leading to low communication efficiency and reliability due to inability to handle multiple transmission modes, resulting in data loss and increased delay.
Innovation Solution
A terminal device is enabled to operate on two or more BWPs, allowing simultaneous unicast and groupcast transmissions, with conditions ensuring compatibility and alignment with network devices, thereby improving communication efficiency and reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a terminal device operates on only one BWP, then the device complexity is reduced and operation is simplified, but communication efficiency deteriorates and the device cannot handle multiple transmission modes simultaneously
Solution Approach 1:
The patent implements dynamic BWP operation by enabling the terminal device to flexibly switch between operating on a single BWP or multiple BWPs based on service requirements. The device can dynamically activate or deactivate BWPs according to whether groupcast or unicast services are needed, optimizing resource utilization while managing complexity adaptively rather than statically
Solution Approach 2:
The patent makes the terminal device multi-functional by enabling it to operate on multiple BWPs simultaneously, allowing the same device to handle both unicast and groupcast transmission modes, as well as different groupcast services, without requiring separate dedicated devices for each function
2Reliability
If a terminal device operates on only one BWP, then energy consumption is reduced, but communication reliability deteriorates due to inability to receive data on multiple BWPs
Solution Approach 1:
The patent implements dynamic energy management by enabling the terminal device to activate multiple BWPs only when needed for specific services (groupcast or unicast), and deactivate them when not required, thus maintaining high communication reliability while avoiding continuous energy consumption associated with monitoring multiple BWPs
3Adaptability or versatility
If a terminal device operates on multiple BWPs, then communication efficiency improves and multiple transmission modes can be handled, but device complexity increases
Solution Approach 1:
The patent manages complexity through dynamic activation and deactivation of BWPs based on service requirements. The terminal device monitors indication information from the network and selectively activates only the necessary BWPs for current services, avoiding the need to permanently maintain complex multi-BWP operation capability
Solution Approach 2:
The terminal device autonomously determines whether to operate on one or multiple BWPs by monitoring service type indications from the network and independently activating or deactivating BWPs according to its own capability and current service needs, reducing the burden on network control while managing complexity
