Adaptation Layer Destination Node Determination for Wireless Backhaul
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication standards for wireless backhaul links do not define a proper procedure for processing data packets at the adaptation layer, leading to incorrect transmission of data packets.
Innovation Solution
A communication method where a network node determines whether it is the destination node for a data packet at the adaptation layer and processes the packet accordingly, ensuring correct transmission by delivering or decompressing the packet based on this determination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an adaptation layer is introduced into the wireless backhaul link, then data packet transmission capability is improved, but data packet processing correctness deteriorates due to undefined procedures
Solution Approach 1:
The first entity in the adaptation layer performs self-determination by autonomously checking whether the current network node is the destination node for a received data packet. This self-service mechanism eliminates the need for external control or predefined complex processing procedures, while ensuring correct handling of data packets through local decision-making based on destination node identification.
Solution Approach 2:
The patent implements preliminary action by having the first entity determine the destination node status before performing any data packet processing operations. This preliminary determination step ensures that subsequent processing actions (such as forwarding or terminating the packet) are based on correct identification of the node's role in the data transmission path, preventing processing errors.
2Productivity
If the network node processes the data packet without determining destination node status, then processing speed is improved, but processing accuracy deteriorates
Solution Approach 1:
The patent performs the destination node determination as a preliminary action before the actual data packet processing. By checking whether the current node is the destination node first, the system ensures accurate processing decisions are made in advance, which then enables efficient subsequent processing without requiring complex error checking or correction mechanisms.

AI summary
This disclosure provides communications methods and apparatuses. One method comprises: receiving, by a first entity of an adaptation layer in a network node, a data packet sent by an entity of a lower protocol layer of the adaptation layer, wherein the data packet comprising an adaptation layer header and an adaptation layer payload; and processing the data packet in response to determining whether the network node is a destination node that the data packet is routed to at the adaptation layer.
