Uplink Transmission Stopping for Self-Interference Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Communications terminals face significant interference from their own transmitters operating at adjacent or harmonic frequencies, across different radio access technologies, leading to reduced performance.
Innovation Solution
The method involves obtaining configuration information that indicates when or how to stop uplink transmissions, either in specific absolute time periods or on particular resources, and then implementing these instructions to reduce interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the terminal continues uplink transmission across all radio access technologies, then the uplink communication performance is maintained, but the terminal experiences significant self-interference from its own transmitters operating at adjacent or harmonic frequencies
Solution Approach 1:
The patent implements periodic discontinuation of uplink transmission by configuring the terminal to stop uplink transmission in specific time periods or on specific resources when interference is detected. The network device sends indication information to the terminal to control when uplink transmission should be suspended, creating a periodic pattern of transmission and suspension that reduces self-interference while maintaining overall communication functionality.
2Object-affected harmful factors
If the terminal stops uplink transmission to reduce interference, then the self-interference is reduced, but the uplink communication performance deteriorates
Solution Approach 1:
The patent applies local quality by selectively stopping uplink transmission only in specific time periods or on specific resources where interference occurs, rather than globally stopping all uplink transmission. The network device provides granular control through indication information that specifies exactly when and where uplink transmission should be suspended, allowing the terminal to maintain uplink communication performance in non-interfered periods while reducing self-interference in affected periods.
3Difficulty of detecting and measuring
If the terminal monitors interference from multiple radio access technologies, then the interference detection capability is improved, but the terminal complexity increases
Solution Approach 1:
The patent implements self-service by enabling the terminal to autonomously detect interference from multiple radio access technologies and make decisions about when to stop uplink transmission based on pre-configured criteria. The terminal uses its own received signal strength information and pre-configured thresholds to determine whether interference exceeds acceptable levels, eliminating the need for complex external coordination while improving interference detection capability.

AI summary
Embodiments of this disclosure provide an uplink transmission processing method, an information configuration method, and a related device. The method includes: obtaining (201) configuration information, where the configuration information is configuration information for stopping uplink transmission on a first resource; and stopping (202) uplink transmission based on the obtained configuration information. The configuration information for stopping uplink transmission is used to indicate a maximum quantity of time domain resources stopping uplink transmission in N time domain resources, where N is an integer greater than 1, and a time domain resource is a slot or a symbol.
