Relay Channel Allocation With Time-Aligned Subchannel Coordination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication networks lack an effective mechanism to coordinate channel utilization in relay networks, leading to communication failures due to unmatched channel utilization between access points and relays when they need to switch between multiple subchannels to serve multiple stations.
Innovation Solution
A channel resource coordinated allocation method is implemented through information exchange between access points and relays, ensuring that the operation times of relays and access points align, using first and second channel allocation information to synchronize communication periods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If relay networks use multiple subchannels to serve multiple stations, then network coverage and service capability are expanded, but communication failures occur due to unmatched channel utilization between access points and relays
Solution Approach 1:
The patent implements feedback mechanisms where relays report their channel allocation information to access points, and access points adjust their channel usage based on this feedback. This ensures that both access points and relays operate on synchronized channels, preventing communication failures while maintaining expanded network coverage through multiple subchannels
Solution Approach 2:
The patent introduces channel allocation information as an intermediary element that mediates between access points and relays. This information acts as a coordination mechanism that ensures both parties use the same subchannels at the same time periods, resolving the mismatch problem while allowing the network to utilize multiple subchannels for expanded coverage
2Device complexity
If access points and relays independently allocate channel resources, then device complexity is reduced, but channel utilization coordination fails leading to communication mismatches
Solution Approach 1:
The patent implements preliminary action by having access points and relays exchange and synchronize channel allocation information before actual data transmission begins. This preliminary coordination ensures that both parties are prepared to communicate on the same channels without increasing the complexity of their individual devices during operation
Solution Approach 2:
The patent creates a universal channel allocation information structure that can be used by both access points and relays regardless of their specific configurations. This multi-functional coordination mechanism works across different device types without requiring complex device-specific implementations, maintaining low device complexity while ensuring reliable channel coordination

AI summary
This application provides a channel resource coordinated allocation method and an apparatus. According to the method, in a relay network, channel allocation information is exchanged between a parent node and a child node, to ensure that an operation time period of the child node on a subchannel includes an operation time period that is on the subchannel and that is allocated by the parent node. The subchannel may be an operating channel on which the parent node and the child node communicate with each other. In this way, a communication failure caused by unmatched communication between the parent node and the child node is avoided when the parent node and the child node select a subchannel for transmission. In addition, coordinated utilization of a plurality of channels is implemented
