Wireless Transmission Device Multi-Channel Scheduling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Efficient scheduling in multi-standard wireless communication networks is inadequate, leading to reduced channel utilization efficiency due to difficulties in decoding and interpreting scheduling information across different standards like IEEE 802.11ad and IEEE 802.11ay.
Innovation Solution
The proposed solution involves a transmitting apparatus that transmits DMG beacon frames or announce frames over primary and non-primary channels, using Extended Schedule Elements (ESE) and EDMG_ESE to include all scheduling information for allocations not using the primary channel in EDMG_ESE, while including partial information in ESE, allowing DMG_PCP/AP to accurately schedule allocations without misinterpreting non-primary channel allocations as primary channel allocations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If scheduling information for all channels is included in ESE for backward compatibility, then DMG_PCP/AP can decode scheduling information, but channel utilization efficiency decreases due to misinterpretation of non-primary channel allocations as primary channel allocations
Solution Approach 1:
The patent segments scheduling information by creating two separate elements: ESE (Extended Schedule Element) for primary channel allocations and EDMG_ESE (802.11ay Extended Schedule Element) for non-primary channel allocations. This segmentation allows DMG_PCP/AP to accurately decode primary channel scheduling from ESE without misinterpreting non-primary channel allocations, while 802.11ay STAs can access both elements for complete multi-channel scheduling information.
2Productivity
If multi-channel operation is implemented to improve channel utilization, then bandwidth capacity increases, but complexity of scheduling management increases due to multiple standards coexistence
Solution Approach 1:
The patent implements a universal scheduling framework where ESE serves as a common element readable by both DMG_PCP/AP and 802.11ay STAs for primary channel information, while EDMG_ESE provides extended functionality for 802.11ay multi-channel operations. This multi-functional design allows the system to support both single-channel and multi-channel operations, accommodating different STA capabilities without requiring separate scheduling systems.
Solution Approach 2:
The patent adds a new dimension to scheduling management by introducing channel allocation fields in EDMG_ESE that specify non-primary channel assignments. This dimensional extension allows the system to handle multi-channel allocations explicitly, separating primary channel management (handled by traditional ESE) from non-primary channel management (handled by EDMG_ESE), thereby reducing scheduling complexity in multi-standard environments.
3Adaptability or versatility
If ESE is used for all channel allocations to ensure backward compatibility, then DMG_PCP/AP can interpret scheduling information, but scheduling accuracy decreases for non-primary channel allocations
Solution Approach 1:
The patent introduces EDMG_ESE as an intermediary element that bridges the gap between DMG and 802.11ay standards. While ESE provides backward compatibility for primary channel allocations, EDMG_ESE acts as a mediator that carries explicit non-primary channel allocation information in a format that 802.11ay STAs can interpret accurately, preventing misinterpretation while maintaining compatibility with existing DMG infrastructure.

AI summary
A transmitting apparatus generates at least one of a first type of schedule element corresponding to an allocation involving a single channel and a second type of schedule element corresponding to an allocation involving a plurality of channels and transmits a MAC frame including the schedule element over a first channel. When the allocation involving the plurality of channels includes the first channel, the transmitting apparatus generates a first type of schedule element including information regarding the allocation involving the plurality of channels and generates the second type of schedule element including difference information, and when the allocation involving the plurality of channels does not include the first channel, the transmitting apparatus omits the generation of the first type of schedule element and generates the second type of schedule element including all information of the information regarding the allocation involving the plurality of channels.
