Terminal DRX Assistance Reporting for IDC Interference Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication technologies do not adequately address the energy-saving and interference management needs of terminals using discontinuous reception (DRX) beyond basic energy conservation, failing to meet functional requirements such as in-device coexistence (IDC) interference and limited capability scenarios.
Innovation Solution
Terminals determine DRX assistance information based on energy-saving, IDC interference, or limited capability needs, and send this information to network devices to facilitate optimal DRX configuration, including preferred DRX configuration information, SCS, and frequency domain details, allowing network devices to adjust settings accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the terminal reports preferred DRX configuration information to the base station for energy saving, then energy consumption is reduced, but other functional requirements such as IDC interference management are not met
Solution Approach 1:
The patent extends the DRX assistance information reporting mechanism to serve multiple functions simultaneously. The terminal reports preferred DRX configuration information that can address both energy saving requirements and IDC interference management needs through a unified reporting framework, allowing the base station to configure DRX parameters that achieve dual objectives
2Duration of action of moving object
If the terminal uses DRX for energy saving, then battery life is extended, but IDC interference between devices is not adequately managed
Solution Approach 1:
The patent enables dynamic adjustment of DRX parameters based on different operational scenarios. The terminal determines preferred DRX configuration information tailored to specific conditions (energy saving mode vs. IDC interference scenario) and reports these customized parameters to the base station, which then applies appropriate parameter sets to balance battery life extension with interference management

AI summary
A method for sending assistance information is performed by a terminal. The method includes: determining a requirement for using discontinuous reception (DRX) is in-device coexistence (IDC) interference; determining DRX assistance information corresponding to the IDC interference, in which the DRX assistance information is at least used for indicating DRX configuration information desired by a terminal; and sending the DRX assistance information to a network device.
