BSRP Trigger Frame Aggregation for Wireless Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication protocols do not effectively accommodate communication devices with limited transmit power capabilities, leading to challenges in reliably transmitting acknowledgment packets at the required bandwidth and modulation schemes.
Innovation Solution
The protocol allows for exceptions to standard transmission rules, enabling devices with limited power to transmit acknowledgment packets at narrower bandwidths and lower modulation schemes, ensuring better reception.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If standard transmission rules are applied, then transmission bandwidth and modulation scheme meet protocol requirements, but devices with limited transmit power cannot reliably transmit acknowledgment packets
Solution Approach 1:
The patent applies dynamics by allowing the transmission bandwidth and modulation scheme to be dynamically adjusted based on the transmit power capability of the receiving device. The first communication device determines the transmit power capability of the second device and selects appropriate transmission parameters (narrower bandwidth, lower modulation scheme) for acknowledgment packets, enabling reliable transmission within power constraints.
Solution Approach 2:
The patent implements parameter changes by modifying transmission parameters (bandwidth and modulation scheme) based on the power capability assessment. Instead of using fixed standard parameters, the system changes these parameters to match the receiving device's capabilities, ensuring reliable acknowledgment transmission from low-power devices.
2Reliability
If acknowledgment packets are transmitted at required bandwidth and modulation schemes, then protocol compliance is maintained, but transmission reliability fails for devices with limited power
Solution Approach 1:
The patent changes transmission parameters (bandwidth and modulation scheme) based on the receiving device's power capability. For devices with limited power, the system uses narrower bandwidth and lower modulation schemes, which improves reception reliability while maintaining acceptable transmission efficiency through adaptive parameter selection.
Solution Approach 2:
The system dynamically selects transmission parameters based on real-time assessment of the receiving device's power capability. This dynamic adaptation ensures that acknowledgment packets are transmitted with parameters optimized for the specific device's capabilities, balancing reliability and efficiency.
3Reliability
If uniform transmission parameters are used for all devices, then protocol simplicity is maintained, but devices with limited power cannot transmit reliably
Solution Approach 1:
The patent applies preliminary action by having the first communication device determine the transmit power capability of the second device before transmitting the acknowledgment packet. This advance assessment allows the system to pre-select appropriate transmission parameters, avoiding the need for complex real-time adjustments while ensuring reliable transmission.
Solution Approach 2:
The system changes transmission parameters based on the receiving device's power capability assessment. By implementing this parameter adaptation mechanism, the patent resolves the contradiction between maintaining protocol simplicity and achieving reliable transmission from low-power devices.

AI summary
A first communication device determines that a trigger frame and another frame are to be transmitted to at least a second communication device. The first communication device determines whether the second communication device announced support of aggregation of buffer status report (BSRP) trigger frames with additional frames. In response to the first communication device determining that the second communication device announced support of aggregation of BSRP trigger frames with additional frames, the first communication device generates an aggregate media access control protocol data unit (A-MPDU) to include the BSRP trigger frame and the other frame, and transmits the A-MPDU within a packet. In response to the first communication device determining that the second communication device did not announce support of aggregation of BSRP trigger frames with additional frames, the first communication device transmits a packet having only the BSRP trigger frame.
