eRedcap Capability Reporting for Frequency Separation Scheduling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The self-interference between uplink and downlink transmissions in enhanced reduced capability (eRedcap) terminals causes significant interference, which existing technologies have not adequately addressed.
Innovation Solution
A capability information reporting method that allows eRedcap terminals to report their supported or expected frequency separation to network devices, enabling the network to schedule more targeted and flexible operating frequencies, thereby reducing interference and improving communication efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If eRedcap terminals perform both uplink and downlink transmissions simultaneously, then communication efficiency is improved, but self-interference between uplink and downlink transmissions increases significantly
Solution Approach 1:
The patent changes the frequency parameter by introducing frequency separation between uplink and downlink transmissions. The terminal device reports its frequency separation capability to the network device, which then schedules uplink and downlink transmissions on frequencies that are separated by at least the minimum frequency separation value, thereby reducing self-interference while maintaining communication efficiency
2Reliability
If frequency separation is increased to reduce self-interference, then transmission quality is improved, but available frequency resources for scheduling decrease
Solution Approach 1:
The patent introduces dynamic frequency separation capability reporting, where the terminal device reports its specific frequency separation capability (e.g., 20 MHz, 40 MHz, 60 MHz) to the network device. This allows the network to dynamically adjust the frequency separation based on the terminal's actual capability and current resource availability, rather than using a fixed conservative value, thus optimizing both transmission quality and resource utilization

AI summary
A capability information reporting method includes: reporting first capability information to a network device, where the first capability information is used to indicate a frequency separation supported or expected by the terminal device.
