Terminal Type-Based Resource Allocation for Low-Rate 5G Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing resource allocation methods for smart wearable devices and industrial sensors with low-rate requirements result in resource waste due to inappropriate configuration, as they do not align with their lower data rate needs, leading to inefficient use of network resources.
Innovation Solution
A method and system where terminal devices actively report their type to the network device, allowing the network device to allocate resources based on the terminal type, using messages like RRC setup requests, terminal capability information, or terminal assistance information to optimize resource allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If higher rate configuration is applied to smart wearable devices with low-rate requirements, then network resource allocation follows standard protocols, but network resources are wasted due to excessive allocation
Solution Approach 1:
The patent introduces terminal type as a new parameter that changes the resource allocation parameters. By identifying the terminal as a smart wearable device with low-rate requirements, the network device adjusts the resource allocation parameters (such as bandwidth, power, time slots) to match the actual needs of the device, thereby avoiding resource waste while maintaining standardized allocation procedures
Solution Approach 2:
The patent makes resource allocation dynamic by introducing terminal type-based differentiation. Instead of applying a static high-rate configuration to all terminals, the system dynamically adjusts resource allocation based on the specific terminal type, allowing the network to optimize resource distribution in real-time according to actual device requirements
2Reliability
If four receiving antennas are arranged in smart wearable devices, then 5G protocol requirements are met, but configuration complexity increases without necessary performance improvement
Solution Approach 1:
The patent applies local quality by differentiating configuration requirements based on terminal type. Instead of uniformly applying 5G protocol requirements (four antennas) to all devices, the system applies appropriate configuration only where needed - smart wearable devices with low-rate requirements can use fewer antennas while still complying with their specific protocol requirements, reducing unnecessary complexity
3Measurement precision
If terminal type reporting is implemented, then resource allocation accuracy improves, but communication overhead increases due to additional messages
Solution Approach 1:
The patent merges the terminal type reporting function with existing communication protocols. The terminal type information is reported through existing message types (RRC setup request, terminal capability information, registration request, or terminal assistance information), combining multiple functions into a single communication exchange and minimizing additional overhead

AI summary
Disclosed are a resource allocation method and a system, a terminal device, and a network device. The method includes: sending a message carrying a terminal type of a terminal device to a network device; and receiving resource allocation information of the terminal device, sent by the network device, the resource allocation information being obtained by the network device according to the terminal type. The terminal device can actively report the terminal type to the network device, such that the network device can perform rational resource allocation on the terminal device according to the terminal type, thereby reducing the waste of network resources and improving the rationality of terminal services.
