Dynamic Antenna Beam Distribution for 5G Backhaul
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
5G telecommunication networks face challenges in converging high data rates into backhaul transmission systems, leading to resource-intensive infrastructure requirements and potential network congestion due to the use of higher frequency bands with narrower beam widths, which limits cell coverage and increases latency.
Innovation Solution
Implementing an antenna distribution mechanism that uses base stations to intelligently distribute radio resources, such as antenna beams, between the access network and the backhaul link based on network traffic conditions, allowing for dynamic adjustments to alleviate congestion and optimize bandwidth usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If higher frequency bands are used to increase data rates, then throughput is improved, but beam width becomes narrower which reduces coverage area and increases latency
Solution Approach 1:
The base station dynamically adjusts the distribution of antenna beams between access network and backhaul link based on real-time network traffic conditions. This dynamic allocation allows the system to adapt beam widths and directions to maintain coverage area while utilizing higher frequency bands for increased data rates.
Solution Approach 2:
The system changes physical parameters of antenna beams including beam width, direction, and distribution ratio between access and backhaul links. By adjusting these parameters based on traffic conditions, the system achieves high throughput while maintaining adequate coverage area.
2Productivity
If more base stations are added to increase capacity, then network throughput is improved, but infrastructure complexity and resource requirements increase
Solution Approach 1:
Existing base stations are made multi-functional by enabling them to dynamically switch antenna beams between access network serving and backhaul transmission. This eliminates the need for separate dedicated backhaul infrastructure, increasing network capacity without proportionally increasing infrastructure complexity.
Solution Approach 2:
The system dynamically reallocates antenna resources between access and backhaul functions based on traffic demand. This dynamic resource sharing allows existing infrastructure to provide increased capacity without requiring additional base stations or complex dedicated backhaul networks.
3Productivity
If antenna beams are allocated to backhaul link, then backhaul capacity is improved, but access network coverage is reduced
Solution Approach 1:
The base station continuously monitors network traffic conditions and dynamically adjusts the ratio of antenna beams allocated to backhaul versus access network. This dynamic balancing ensures that backhaul capacity is increased when needed while access coverage is maintained at adequate levels, resolving the trade-off between the two functions.

AI summary
A base station may configure an access beam group to include one or more antenna beams for communicating with one or more user equipment (UE). The base station may configure a backhaul beam group to include one or more antenna beams for communicating with one or more other base stations. The base station may monitor network traffic associated with the access beam group and/or the backhaul beam group, and may determine that the network traffic satisfies a condition. The base station may modify the access beam group and/or the backhaul beam group to add or remove at least one antenna beam based on determining that the network traffic satisfies the condition.
