P2P QoS TXOP Sharing for Multi-Link Wireless Stations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems lack mechanisms for efficient Quality of Service (QoS) support in peer-to-peer (P2P) communication, particularly in multi-link devices (MLDs), limiting the ability of non-AP STAs to request and utilize transmit opportunities (TXOPs) for both uplink and P2P communication.
Innovation Solution
Implementing mechanisms for non-AP devices to form links with APs, request TXOPs using MU-RTS TXS frames, and determine the usage of TXOPs for uplink or both uplink and P2P communication, enabling dynamic QoS support through TXOP sharing modes.

Engineering Contradiction Analysis
1Reliability
If non-AP STAs can request and utilize TXOPs for both uplink and P2P communication, then QoS support for P2P communication is improved, but device complexity increases due to multiple link management requirements
Solution Approach 1:
The patent segments the TXOP allocation mechanism by introducing distinct TXOP sharing modes (uplink-only mode and uplink-plus-P2P mode) that can be independently selected and configured. This segmentation allows the system to handle P2P communication requirements without complicating the entire multi-link device management, as each link can operate in its appropriate mode based on specific needs.
2Productivity
If TXOP sharing modes are implemented for both uplink and P2P communication, then resource allocation efficiency is improved, but the difficulty of detecting and measuring TXOP usage increases
Solution Approach 1:
The patent implements feedback mechanisms where the AP receives TXOP sharing mode indication information from non-AP STAs and responds with appropriate TXOP allocations. The system continuously monitors and adjusts TXOP usage based on feedback from multiple STAs, enabling efficient resource allocation while maintaining manageable detection and measurement through structured feedback loops rather than complex monitoring of all possible interactions.

AI summary
Methods and apparatuses for supporting QoS support for P2P communication. A method for wireless communication performed by a non-access point (AP) device that includes a first station (STA) comprises: forming a link with a first AP; forming a first peer-to-peer (P2P) link with a second non-AP STA; transmitting a request associated with a transmit opportunity (TXOP) to the AP; receiving information associated with the TXOP from the AP; and determining whether the received information associated with the TXOP can be used only for uplink communication or for both uplink communication and P2P communication.
