Authorized Frequency Band Allocation for Low-Latency Device Links
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems face challenges in effectively utilizing spectrum resources for high-rate and low-latency short-range wireless communication between user terminals and peripheral devices, leading to inefficiencies and potential interference.
Innovation Solution
A connection management method where a first device requests and obtains authorization from a network device to use a second frequency band for communication, allowing it to initiate a connection with a second device using a device identity, thereby avoiding interference and optimizing spectrum use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a first device directly uses a frequency band for communication with a second device without authorization, then communication speed and latency are improved, but spectrum resource management deteriorates and interference increases
Solution Approach 1:
The system performs preliminary authorization actions before actual communication begins. The network device pre-approves which frequency bands can be used for device-to-device communication, establishing a framework that enables fast communication while maintaining spectrum management control.
Solution Approach 2:
The network device acts as an intermediary that mediates between the first device's need for fast communication and the spectrum management requirements. It provides authorization information that allows direct communication while maintaining overall spectrum coordination.
2Reliability
If spectrum resources are strictly controlled by network device, then interference is reduced, but communication efficiency and speed deteriorate
Solution Approach 1:
The frequency band is segmented into different portions - some used for traditional network communication and other portions authorized for direct device-to-device communication. This segmentation allows simultaneous interference-controlled network management and efficient direct communication.
Solution Approach 2:
Instead of fully controlling all frequency bands through the network device, the system applies partial control by authorizing specific bands for direct communication. This partial action maintains interference control where needed while enabling efficient communication where appropriate.
3Reliability
If device identity verification is implemented, then security and reliability are improved, but connection establishment time increases
Solution Approach 1:
Device identity information is verified and authorized in advance by the network device before direct communication begins. This preliminary verification enables fast connection establishment while maintaining security requirements.

AI summary
This application provides a connection management method and a device. A first device sends resource request information to a network device, where the resource request information is used to request the network device to authorize the first device to use a first frequency band for communication, and the first frequency band is a frequency band used by a second device for communication; the first device receives response information sent by the network device, where the response information is used to indicate that the network device authorizes the first device to use a second frequency band for communication, and the second frequency band is a part or the entirety of the first frequency band; and the first device initiates a communication connection in the second frequency band based on a device identity of the second device. The connection management method in this application can effectively implement high-rate and low-latency short-range wireless communication by using spectrum resources.
