Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face inefficiencies in handling multiple beam collisions, particularly in duplexing enhancements, where traditional methods restrict simultaneous downlink and uplink transmissions due to interference, limiting data throughput and latency improvements.
Innovation Solution
The method involves a User Equipment (UE) receiving indications of multiple frequency resources and Slot Format Indicators (SFIs) from a base station to determine whether to perform or cancel uplink transmissions based on specific beam associations, allowing for flexible transmission directions on applicable beams, thereby enhancing duplexing efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If traditional duplexing methods are used to avoid beam collisions, then interference between downlink and uplink is reduced, but data throughput is limited and latency increases
Solution Approach 1:
The patent segments the frequency resources into first frequency resources associated with first beams and second frequency resources associated with second beams. This segmentation allows independent handling of duplexing for different beams, enabling simultaneous downlink and uplink transmissions on different frequency resources without interference, thereby resolving the contradiction between avoiding interference and improving data throughput.
Solution Approach 2:
The patent introduces beam dimension as a new differentiation axis alongside frequency resources. By associating frequency resources with specific beams, the system creates a multi-dimensional resource allocation space (frequency × beam), allowing simultaneous transmissions in different dimensions without mutual interference, thus improving throughput while maintaining interference avoidance.
2Productivity
If frequency resources are dynamically allocated based on beam conditions, then duplexing efficiency is improved, but collision handling complexity increases
Solution Approach 1:
The base station provides indications of frequency resources and slot format indicators in advance before the actual transmissions occur. This preliminary action allows the UE to pre-determine which frequency resources to use for uplink transmissions, reducing the complexity of real-time collision handling while maintaining high duplexing efficiency through proactive resource allocation.
Solution Approach 2:
The system employs feedback mechanisms where the base station provides indications of frequency resources and slot format indicators to the UE. This feedback loop enables dynamic adaptation to beam conditions while simplifying collision handling by providing clear guidance on resource allocation, thus resolving the contradiction between efficiency and complexity.
3Adaptability or versatility
If slot format indicators are provided for multiple beams, then transmission flexibility is enhanced, but processing requirements for collision handling increase
Solution Approach 1:
The patent applies local quality by providing slot format indicators specifically for frequency resources associated with particular beams rather than applying a uniform format across all resources. This localized approach enhances transmission flexibility for specific beam conditions while reducing processing requirements by avoiding the need to evaluate all possible beam combinations simultaneously.

AI summary
Methods, systems, and apparatuses for multiple beam collision handling in a wireless communication system. A method for a User Equipment (UE) in a wireless communication system can comprise receiving indication of one or more first frequency resources associated with Uplink (UL) for a first beam and/or a first set of beams from a base station, determining whether to perform or cancel a first UL transmission based on the one or more first frequency resources when the first UL transmission is associated with the first beam and/or the first set of beams, and not determining whether to perform or cancel a second UL transmission based on the one or more first frequency resources when the second UL transmission is associated with a second beam and/or a second set of beams.
