P2P Buffer Status Signaling for WLAN Resource Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems lack efficient methods for an access point to inquire about the buffer status of peer-to-peer traffic between non-access point devices, leading to inefficient resource allocation in wireless local area networks.
Innovation Solution
A new signaling method is introduced to redefine the buffer status report poll trigger frame to include specific fields or bits that indicate a request for peer-to-peer traffic buffer status, allowing non-access point devices to report their peer-to-peer traffic buffer status to the access point.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing wireless communication systems use traditional buffer status inquiry methods, then access point can manage uplink traffic, but it cannot efficiently inquire about peer-to-peer traffic buffer status between non-access point devices
Solution Approach 1:
The trigger frame structure is extended to serve multiple functions: it can inquire about uplink buffer status (traditional function) and peer-to-peer buffer status (new function) by simply modifying the buffer status report polling information field to include a peer-to-peer traffic identifier. This allows a single signaling mechanism to handle multiple types of buffer status inquiries without requiring separate dedicated frames for each purpose.
Solution Approach 2:
The patent modifies existing frame parameters rather than creating entirely new frame structures. Specifically, it changes the interpretation and content of the buffer status report polling information field in trigger frames to include peer-to-peer traffic identifiers and queue size indicators. This parameter modification approach enables new functionality while maintaining compatibility with existing wireless communication protocols and reducing signaling complexity.
2Productivity
If access point allocates resources without peer-to-peer buffer status information, then resource allocation is simpler, but network performance and latency are degraded
Solution Approach 1:
The patent implements a feedback mechanism where non-access point devices report their peer-to-peer traffic buffer status back to the access point through modified trigger frames. The buffer status report polling information field carries feedback information including queue size indicators and traffic identifiers. This feedback loop enables the access point to make informed resource allocation decisions based on actual buffer conditions, improving network performance while maintaining manageable complexity through structured information exchange.
3Loss of information
If traditional buffer status report frames are used, then uplink buffer status can be reported, but peer-to-peer traffic buffer status cannot be indicated
Solution Approach 1:
The patent embeds peer-to-peer traffic status information within the existing buffer status report frame structure. The buffer status report polling information field contains nested elements including traffic identifiers and queue size indicators that specifically describe peer-to-peer traffic conditions. This nesting approach allows additional information to be carried within the existing frame format without requiring completely new frame structures, thus reducing complexity while preventing information loss.
Data Source
AI summary
A first device may include one or more processors. The one or more processors may be configured to generate a first frame including buffer status data corresponding to wireless traffic between the first device and a second device. Each of the first device and the second device may not be an access point. The one or more processors may be configured to wirelessly transmit, via a transceiver, the generated first frame to an access point in a wireless local area network (WLAN).
