Terminal Data Demodulation via Resource Indication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In fifth-generation communication technologies, the inefficiency and inaccuracy of data demodulation occur due to the lack of awareness by eMBB user equipment (UE) of resources occupied by URLLC UE, which affects resource usage and delay requirements.
Innovation Solution
A method and device where a terminal acquires indication information from a base station about second time-frequency resources allocated to other terminals, allowing it to decode data only in its own resources and improve demodulation efficiency and accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the base station allocates time-frequency resources to multiple terminals to improve resource usage efficiency, then resource usage efficiency is improved, but the terminal becomes unaware of resources occupied by other terminals, resulting in lower demodulation efficiency and accuracy
Solution Approach 1:
The patent introduces indication information as an intermediary mechanism transmitted from the base station to the terminal. This indication information explicitly notifies the terminal about time-frequency resources allocated to other terminals, enabling the terminal to accurately identify and avoid decoding these resources, thus resolving the contradiction between resource sharing and demodulation accuracy
Solution Approach 2:
The base station provides feedback information (indication information) to the terminal regarding resource allocation status. This feedback mechanism allows the terminal to update its knowledge of available resources in real-time, ensuring accurate demodulation while maintaining efficient resource usage across multiple terminals
2Productivity
If the terminal decodes data in all scheduled time-frequency resources without knowing resource occupation by other terminals, then the terminal can attempt to decode all resources, but this results in wasted computational resources and reduced demodulation efficiency
Solution Approach 1:
The patent extracts the problematic resources (time-frequency resources occupied by other terminals) from the set of scheduled resources. Through indication information, the terminal identifies and separates these resources, choosing not to decode them, thereby avoiding wasted computational energy while maintaining efficiency in decoding only the terminal's allocated resources

AI summary
A method and a device for processing data are provided according to embodiments of the present disclosure. The method is carried out as follows. A terminal acquires indication information sent by a base station, the indication information is indicative of information of second time-frequency resources, and the second time-frequency resources are part of first time-frequency resources scheduled to the terminal and are allocated by the base station to other terminals. The terminal decodes data transmitted in resources in the first time-frequency resources other than the second time-frequency resources according to the indication information.
