Multi-user Group Assignment Records for Wireless Signaling Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in efficiently managing multi-user communication groups and signaling, particularly in scenarios where the number of user elements exceeds the allocated resource blocks, leading to inefficiencies in acknowledgement transmission and reception.
Innovation Solution
The implementation of a technique that maintains assignment records for multi-user communication groups, including assigned group identifiers and member identifiers, to generate and transmit assignment messages that update and filter transmissions based on a multi-user group table, allowing for efficient initialization and management of group assignments.

Engineering Contradiction Analysis
1Quantity of substance
If the number of user elements exceeds the allocated resource blocks in multi-user communication groups, then the system can support more users, but transmission efficiency deteriorates due to inefficiencies in acknowledgement transmission and reception
Solution Approach 1:
The patent segments the multi-user communication group into smaller sub-groups or assigns users to different resource blocks in a structured manner. By maintaining assignment records that map specific users to specific resource blocks and organizing them into manageable groups, the system can efficiently handle acknowledgements for each segment separately, thereby maintaining transmission efficiency even when the total number of users exceeds the number of resource blocks
Solution Approach 2:
The patent implements preliminary assignment of users to resource blocks and communication groups before actual data transmission. The access point maintains assignment records that pre-configure which users should receive acknowledgements on which resource blocks. This preliminary organization allows the system to efficiently manage user-resource block mappings and transmit acknowledgements without delays, even when user数量 exceeds resource block数量
2Reliability
If assignment records are maintained for all multi-user communication groups, then accurate acknowledgement routing is achieved, but system complexity increases
Solution Approach 1:
The patent implements a universal assignment record structure that serves multiple functions simultaneously. The same assignment record mechanism is used for both initial user-to-resource-block assignment and for routing acknowledgements. This multi-functional approach ensures reliable acknowledgement routing without requiring separate complex systems, thereby maintaining reliability while controlling system complexity
Solution Approach 2:
The patent uses simplified assignment record copies or references rather than maintaining complete detailed mappings for every user-resource block combination. The access point maintains essential assignment information that can be used to determine acknowledgement routing without storing excessive detail. This copying approach ensures accurate routing while reducing the complexity and memory requirements of the system

AI summary
Systems and techniques relating to wireless communications are described. A described technique includes generating one or more assignment records for a wireless communication device, generating an assignment message that includes the one or more generated assignment records, and transmitting the assignment message to cause the wireless communication device to initialize or update a multi-user group table based on the assignment message and filter one or more received multi-user transmissions based on the multi-user group table. The assignment message can indicate one or more group identifiers and one or more group member identifiers that are assigned to the wireless communication device and one or more group identifiers that are not assigned to the wireless communication device.
