UCI Multiplexing on Configured Grant PUSCH via Beta Offset Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems are unable to effectively multiplex uplink control information (UCI) transmissions of different priorities with physical uplink shared channel (PUSCH) transmissions, limiting network efficiency and performance due to restrictive priority matching requirements.
Innovation Solution
The system determines whether a UCI transmission of one priority can be multiplexed with a PUSCH transmission of another priority by selecting a beta offset value from sets configured by the base station, allowing for flexible multiplexing based on priority configurations signaled to the user equipment (UE).
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If UCI transmission and PUSCH transmission of different priorities are multiplexed, then resource utilization and network capacity are improved, but priority management complexity and resource allocation overhead increase
Solution Approach 1:
The patent segments priority management by introducing separate priority fields for UCI (first priority) and PUSCH (second priority) transmissions. This allows independent priority assignment and multiplexing decisions for different transmission types, reducing the complexity of managing mixed-priority traffic while enabling flexible resource allocation and improving overall productivity.
2Adaptability or versatility
If multiple sets of beta offset values are configured for different priorities, then multiplexing flexibility is improved, but signaling overhead and configuration complexity increase
Solution Approach 1:
The patent implements partial configuration by providing multiple sets of beta offset values only when needed for specific priority combinations. The base station can configure one or more sets based on actual network requirements, avoiding the overhead of always configuring all possible combinations. This selective configuration approach maintains multiplexing flexibility while reducing unnecessary signaling overhead.
3Reliability
If beta offset values are selected from multiple configured sets, then transmission performance is improved, but processing complexity at UE increases
Solution Approach 1:
The patent applies preliminary action by having the base station pre-configure multiple sets of beta offset values before actual transmissions occur. The UE stores these pre-configured sets and simply selects from them based on the detected priority combination, rather than calculating optimal values in real-time. This reduces UE processing complexity during transmission while maintaining the ability to optimize performance through multiple pre-computed options.

AI summary
Systems and method for configuring and providing uplink control information (UCI) multiplexing on physical uplink shared channel (PUSCH) transmissions are disclosed. In embodiments, a base station configures and signals, to a user equipment (UE) a plurality of sets of beta-offset values to be used by the UE for multiplexing a UCI transmission of a first priority to a PUSCH transmission of a second priority. Each set of the plurality of sets of beta-offset values is configured based on the second priority of the PUSCH transmission. In embodiments, the UE determines whether the UCI transmission of the first priority is allowed to be multiplexed to the PUSCH transmission of the second priority, and multiplexes the UCI to the PUSCH when multiplexing of the UCI and PUSCH is allowed, using a beta-offset value from the plurality of sets of beta-offset values. Other aspects and features are also claimed and described.
