Service Period Parameter Scheduling for Wireless Frame Exchange
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in efficiently scheduling service period parameters for frame exchange procedures, leading to suboptimal resource utilization and increased signaling overhead.
Innovation Solution
The method involves a first wireless device transmitting frame exchange parameters associated with a scheduled service period to a second wireless device, allowing them to communicate efficiently during that period. This approach enables the configuration of frame exchange parameters to optimize resource usage and reduce signaling overhead.

Engineering Contradiction Analysis
1Productivity
If frame exchange parameters are configured dynamically for each service period, then resource utilization is optimized and network throughput is improved, but signaling overhead increases
Solution Approach 1:
The patent applies preliminary action by configuring frame exchange parameters in advance during service period establishment rather than dynamically during each frame exchange. The access point pre-configures parameters such as modulation and coding scheme, spatial streams, and bandwidth in the trigger frame that initiates the service period, eliminating the need for repeated signaling during actual data transmission and thus reducing signaling overhead while maintaining optimized resource utilization
Solution Approach 2:
The patent implements universality by creating a multi-functional trigger frame that simultaneously serves as a service period establishment message and a frame exchange parameter configuration message. This single frame performs multiple functions: it schedules the service period, configures transmission parameters, and initiates the data exchange, thereby reducing the need for separate signaling messages and lowering overall signaling overhead
2Productivity
If service period parameters are scheduled with high precision, then resource allocation is optimized, but device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the scheduling process into distinct phases: service period establishment phase where parameters are pre-configured, and data transmission phase where pre-configured parameters are used. This segmentation allows complex parameter configuration to occur only once during establishment, while the actual data transmission uses simple, pre-determined parameters, thus optimizing resource allocation without requiring continuous complex scheduling operations
Solution Approach 2:
The patent implements parameter changes by allowing frame exchange parameters to be set to specific values during service period establishment and then maintaining those parameter values throughout the service period. Parameters such as modulation scheme, coding rate, and spatial streams are changed from variable to fixed values during the service period, reducing the computational complexity of real-time scheduling decisions while maintaining optimized resource allocation

AI summary
This disclosure provides methods, components, devices, and systems for service period parameter scheduling for frame exchange procedures. In some examples, a first wireless device (such as an access point (AP), a station (STA)), may communicate with a second wireless device (such as a STA, an AP) during a scheduled service period. The first wireless device may indicate an upper or lower limit for communication parameters used by the first wireless device and the second wireless device during the service period. The first wireless device may communicate with the second wireless device according to the limited parameters. In some examples, the first wireless device may be available to communicate with other wireless devices outside of the scheduled service period. In such examples, the first wireless device may communicate with the other wireless devices according to a second set of parameters indicated alongside the first set of parameters.
