Multi-link Peer Grouping via Group ID Scheduling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional multi-link systems in peer-to-peer communications require all links to terminate at the same MAC entity, limiting flexibility and efficiency in resource allocation and scheduling.
Innovation Solution
The system allows individual links of a multi-link device to terminate on different MAC entities, enabling peer groups to form and use group IDs for resource allocation and scheduling, allowing peer-to-peer devices to communicate efficiently and flexibly by leveraging multiple links with separate MAC entities, including APs and other peer devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If all links terminate at the same MAC entity, then the system maintains conventional multi-link operation, but flexibility and efficiency in resource allocation and scheduling are limited
Solution Approach 1:
The patent segments the MAC entity requirement by allowing different links to terminate at different MAC entities (first MAC entity for first link, second MAC entity for second link). This segmentation enables independent resource allocation and scheduling for each link, resolving the contradiction between flexibility and complexity by distributing MAC entity responsibilities across multiple entities rather than consolidating them.
Solution Approach 2:
The patent introduces a new dimension to multi-link operations by adding group ID-based scheduling alongside traditional MAC address-based addressing. This dimensional expansion allows the system to manage multiple links with different MAC entities through a unified group ID framework, enhancing flexibility without proportionally increasing complexity.
2Productivity
If individual links terminate on different MAC entities, then flexibility and efficiency in resource allocation improve, but scheduling complexity increases
Solution Approach 1:
The patent creates a universal group ID that can identify multiple peer devices simultaneously, serving as a multi-functional identifier that replaces traditional individual MAC address-based scheduling. This universal group ID mechanism handles scheduling for multiple links terminating at different MAC entities, improving productivity while managing complexity through a unified identification approach rather than separate scheduling mechanisms for each link.
Solution Approach 2:
The group ID acts as an intermediary between the AP and multiple peer devices with different MAC entities. Instead of the AP directly managing each MAC entity separately, the group ID mediates resource allocation and scheduling across multiple links, improving efficiency by reducing the scheduling burden while maintaining necessary coordination through the intermediary group identifier.
3Loss of time
If peer devices use group IDs for communication, then scheduling efficiency improves, but compatibility with conventional MAC address-based systems decreases
Solution Approach 1:
The patent merges traditional MAC address-based identification with group ID-based identification in a hybrid addressing framework. Peer devices can be identified by MAC addresses for individual link communication while simultaneously being members of groups identified by group IDs for efficient multi-link scheduling. This merging allows the system to capture scheduling efficiencies of group-based approaches while maintaining compatibility with conventional MAC address-based communication protocols.
Data Source
AI summary
Techniques for improved peer-to-peer grouping in multi-link operations are provided. An indication of radio frequency (RF) capabilities of a peer-to-peer device is transmitted, and the peer-to-peer device receives a group ID assigned by a wireless access point (AP) based on the RF capabilities, where the group ID is associated with a set of links that can be used for peer-to-peer communications between peer-to-peer devices in a first group of peer-to-peer devices. The peer-to-peer device can request that the AP schedule a transmission opportunity for a first peer-to-peer communication using the group ID. In response to receiving a trigger frame comprising the group ID, the first peer-to-peer device performs the first peer-to-peer communication using the transmission opportunity.
