Multi-Point Transmission Resource Allocation via Backhaul Status
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In intensive cellular networks, the limited backhaul resources of cells can hinder the efficiency of multi-point transmission, making it challenging to determine optimal resource allocation for participating cells, which affects the overall performance of edge users and network efficiency.
Innovation Solution
A method and apparatus that determine multi-point transmission resources by obtaining backhaul statuses and available access resources of multiple cells, including a primary and secondary cell, to calculate the maximum backhaul and access transmission rates, and allocate resources based on the type of multi-point transmission (coordinated or cooperative) to ensure service requirements are met.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multi-point transmission is used to improve edge user performance, then channel quality and throughput are improved, but backhaul resource limitations reduce transmission efficiency
Solution Approach 1:
The patent dynamically determines multi-point transmission resources based on real-time backhaul status and available access resources. The system adjusts resource allocation adaptively by calculating maximum backhaul rates and available access resources, and determining optimal access resources for multi-point transmission according to transmission type and service requirements, rather than using fixed resource allocation.
2Quantity of substance
If more cells are deployed to improve coverage and capacity, then network capacity increases, but backhaul resource insufficiency lowers multi-point transmission efficiency
Solution Approach 1:
The patent changes the parameter of resource allocation by determining access resources based on backhaul status and available access resources. The system calculates maximum backhaul rates from backhaul status, obtains available access resources, and determines optimal access resources for multi-point transmission, thereby adapting resource allocation to the actual network capacity and backhaul conditions.
3Productivity
If backhaul resources are increased to support more multi-point transmission, then transmission efficiency improves, but system complexity and cost increase
Solution Approach 1:
The system performs self-service by autonomously determining optimal multi-point transmission resources based on its own backhaul status and available access resources. The network element calculates maximum backhaul rates, obtains available access resources, and determines access resources for multi-point transmission without requiring external intervention or complex manual configuration, thereby improving efficiency without proportionally increasing operational complexity.
