Dynamic Triggered TXOP Sharing Modes for P2P and Uplink SU
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communications systems lack effective signaling for dynamically enabling, disabling, or suspending triggered transmission opportunity (TXOP) sharing procedures, particularly for peer-to-peer (P2P) and uplink single-user (SU) transmissions, leading to increased latency and reduced quality of real-time applications.
Innovation Solution
Implementing capability and operation indications in TXOP sharing procedures to allow wireless devices to dynamically select and switch between supported TXOP sharing modes, including peer-to-peer (P2P) and uplink single-user (SU) transmissions, by using frames to indicate changes in support and trigger data transmissions accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If traditional TXOP sharing procedures are used without dynamic mode selection, then the system maintains simple signaling protocols, but real-time applications experience increased latency and reduced communication quality
Solution Approach 1:
The patent implements dynamic TXOP sharing modes where wireless devices can switch between different operation modes (triggered P2P mode, triggered uplink SU mode, or untriggered mode) based on real-time communication requirements. This is achieved through capability indication messages exchanged during association and operational mode indication messages transmitted during operation, allowing the system to adapt signaling complexity to actual needs while reducing latency for real-time applications.
2Reliability
If dynamic TXOP sharing mode selection is implemented, then communication quality for real-time applications is enhanced, but the signaling protocol complexity increases
Solution Approach 1:
The patent segments the TXOP sharing functionality into distinct operational modes (triggered P2P mode, triggered uplink SU mode, untriggered mode) with specific capability indications for each. This segmentation allows the system to enable dynamic mode selection and improve communication quality while managing signaling complexity by organizing functionality into discrete, well-defined modes rather than a monolithic complex protocol.
3Adaptability or versatility
If fixed TXOP sharing modes are used, then the system maintains ease of operation, but adaptability to different real-time application requirements is reduced
Solution Approach 1:
The patent creates a universal TXOP sharing framework that supports multiple operational modes within a single system. Wireless devices can indicate support for different modes through capability messages and switch between modes during operation based on application requirements. This multi-functionality approach enables the system to adapt to various real-time application needs while maintaining a unified operational structure that preserves ease of use.

AI summary
Methods, systems, and devices for wireless communications are described. A first wireless device and a second wireless device (e.g., access points, stations) may support transmission opportunity (TXOP) sharing procedures. The second wireless device may transmit a frame indicating a capability of the second wireless device to support one or more triggered TXOP sharing modes. The second wireless device may transmit an indication (e.g., a frame) indicating to change support for the triggered TXOP sharing modes based on the capability. The change may indicate to suspend, resume, disable, or enable the triggered TXOP sharing modes. For example, the second wireless device may transmit an indication to suspend support of a first triggered TXOP sharing mode that enables the second wireless device to perform peer-to-peer transmissions. Accordingly, the first wireless device may trigger the second wireless device to communicate according to the supported triggered TXOP sharing modes.
