Uplink Control Information Multiplexing via Beta Offset Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication standards, such as those defined by the 3GPP, lack a mechanism to efficiently multiplex uplink control information (UCI) of different priorities, leading to suboptimal resource management and spectral efficiency, particularly when high and low priority UCI transmissions overlap.
Innovation Solution
The proposed solution involves multiplexing high and low priority UCI bits on a Physical Uplink Shared Channel (PUSCH) using separate beta offset configurations, allowing for dynamic resource allocation based on priority, as indicated by beta offset values signaled through downlink control information, enabling flexible scheduling without sacrificing quality of service.

Engineering Contradiction Analysis
1Productivity
If separate beta offset configurations are used for high and low priority UCI multiplexing, then spectral efficiency and resource management are improved, but device complexity and processing overhead increase
Solution Approach 1:
The patent segments the beta offset configuration into separate sets for high priority and low priority UCI. The network device configures multiple beta offset values (e.g., betaOffsetHARQ-ACK Index1, Index2, Index3 for high priority; betaOffsetHARQ-ACK Index4, Index5, Index6 for low priority) and the terminal device selects appropriate values based on priority, enabling differentiated resource allocation without requiring complete reconfiguration of the system.
Solution Approach 2:
The patent implements dynamic selection of beta offset values based on UCI priority. The terminal device determines the priority of each UCI (high or low) and dynamically selects from the configured beta offset sets accordingly. This dynamic adaptation allows the system to optimize resource allocation in real-time based on traffic conditions and priority requirements.
2Productivity
If high priority UCI is multiplexed with low priority UCI on PUSCH, then resource utilization is improved, but the reliability of high priority transmission may be compromised
Solution Approach 1:
The patent applies local quality by allocating different beta offset values to different priority levels within the same PUSCH transmission. High priority UCI is assigned larger beta offset values (e.g., Index1-3) that provide more robust modulation and coding, while low priority UCI uses smaller beta offset values (e.g., Index4-6). This ensures that each priority level receives appropriate quality of service while sharing the same physical channel.
Solution Approach 2:
The patent changes the beta offset parameter based on UCI priority to control resource allocation and transmission reliability. By adjusting the beta offset values dynamically according to priority, the system can ensure that high priority UCI maintains sufficient reliability even when multiplexed with low priority UCI, while still achieving improved overall resource utilization compared to separate transmissions.

AI summary
This disclosure describes systems, methods, and devices related to multiplexing uplink transmissions. A user equipment (UE) device may detect a first set of beta offset indices associated with multiplexing high priority uplink control information (UCI) into a physical uplink shared control channel (PUSCH); detect a second set of beta offset indices associated multiplexing low priority UCI into the PUSCH; detect downlink control information (DCI) using a physical downlink control channel (PDCCH) which schedules the PUSCH; determine, based on the first set of beta offset indices and the second set of beta offset indices, that UE device is to multiplex the high priority UCI with the low priority UCI into the PUSCH; and encode, based on the second set of beta offset indices, a multiplexed uplink transmission for transmission to the 5G network device using the PUSCH, the multiplexed uplink transmission comprising the high priority UCI and the low priority UCI.
