P2P TXOP Coordination for Coexistence-Constrained Stations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems lack mechanisms for efficiently informing peer-to-peer (P2P) stations about coexistence constraints, leading to unmanaged traffic that interfere with low-latency applications, which the access point (AP) cannot effectively control.
Innovation Solution
A framework is provided for a first station to request a transmit opportunity (TXOP) from the AP, allowing it to inform a second station about its unavailability due to coexistence events, using messages that include information on coexistence constraints.

1Object-affected harmful factors
If stations transmit without coordination, then communication freedom is maintained, but coexistence constraints cause interference and network performance degradation
Solution Approach 1:
The patent introduces an intermediary mechanism where the first station acts as a mediator by informing the second station about coexistence constraints through structured messages. This intermediary communication resolves the interference problem by enabling coordinated transmission decisions without requiring complex centralized control, thus reducing overall system complexity while eliminating harmful interference.
2Reliability
If the first station informs the second station about coexistence constraints, then P2P link management is improved, but additional messaging overhead is introduced
Solution Approach 1:
The patent applies preliminary action by having the first station proactively inform the second station about upcoming coexistence constraints before the actual transmission occurs. This advance notification allows the second station to prepare appropriate responses or adjust its transmission schedule, improving reliability of P2P link management while minimizing messaging overhead by communicating only essential constraint information.

Methods and apparatuses for TXOP for P2P communication. A method performed by a STA includes indicating, to a second STA, that the first STA has a coexistence constraint; and transmitting, to the second STA, a message that includes information pertaining to the coexistence constraint.
