P2P Resource Request Signaling for WLAN Bandwidth Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless local area networks (WLANs), efficient resource allocation is hindered by the need for multiple devices to share resources, with some devices limited by their communication protocols or hardware bandwidth, and the challenge of coexisting with both newer and legacy protocols.
Innovation Solution
The implementation of a radio architecture that includes both WLAN and Bluetooth functionality, using front-end module, radio IC circuitry, and baseband processing circuitry to enable point-to-point resource allocation through advanced signaling methods, allowing for efficient resource management and coexistence with different protocols.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple devices share the same wireless resources, then network coverage and connectivity are improved, but bandwidth availability and response times deteriorate
Solution Approach 1:
The patent segments the wireless channel into multiple resource units (RUs) that can be independently allocated to different stations. The channel is divided into smaller units that can be dynamically assigned based on individual station requirements, allowing multiple devices to share resources simultaneously without completely degrading each other's performance.
Solution Approach 2:
The patent implements dynamic resource allocation where the access point can dynamically adjust which resource units are assigned to which stations based on real-time conditions. This dynamic scheduling allows the system to adapt to changing traffic patterns and station requirements, optimizing bandwidth availability while maintaining connectivity for all devices.
2Productivity
If devices use newer communication protocols, then data transmission efficiency is improved, but compatibility with legacy devices deteriorates
Solution Approach 1:
The patent implements a universal resource allocation mechanism that works across multiple protocol versions. The access point uses a standardized trigger frame format that can be understood by both legacy and newer protocol devices, allowing the system to maintain compatibility while enabling efficient resource sharing. The mechanism serves multiple protocol requirements through a single unified approach.
3Manufacturing precision
If resource allocation is done manually or through complex signaling, then allocation precision is improved, but device complexity and operational difficulty increase
Solution Approach 1:
The patent implements a self-service resource allocation mechanism where stations automatically report their buffer status and resource requirements to the access point. The access point then automatically allocates appropriate resource units without requiring manual configuration or complex negotiation protocols. Stations autonomously manage their own resource needs through simple buffer status reports and acknowledgment frames.

Methods, apparatuses, and computer readable media for point-to-point (P2P) resource request signaling, where an apparatus of an station (STA) comprises processing circuitry configured to: encode, for transmission to an access point (AP), a first frame comprising a P2P resource request, the P2P resource request comprising an airtime field, the airtime field, indicating a duration, and a channel bandwidth (BW), the channel BW indicating a channel bandwidth, and decode, from the AP, a second frame, the second frame comprising a P2P resource grant in accordance with the P2P resource request. The processing circuitry may be further configured to encode, for transmission to a second STA, in accordance with the P2P resource grant, a third frame.
