Dynamic SSB Beam Allocation for Relay Backhaul Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication networks, when a relay device and multiple user devices are served by the same beam, network resources can become insufficient, leading to decreased user experience due to resource overextension, especially when the relay device consumes more resources by providing backhaul services.
Innovation Solution
A system and method for dynamically reallocating SSB beams, where user devices are redirected to a secondary beam with a signal strength within a predetermined threshold of the primary beam used by the relay device, ensuring the relay device maintains strong signaling while user devices receive adequate coverage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a relay device and multiple user devices are served by the same beam, then the relay device can provide backhaul services to user devices, but network resources become insufficient and user experience decreases due to resource overextension
Solution Approach 1:
The patent segments the user devices from the relay device by assigning them to different beams. The network device identifies user devices that are served by the same beam as a relay device, then redirects these user devices to different beams. This segmentation separates the resource-intensive relay device operations from regular user device operations, preventing resource overextension while maintaining the relay device's backhaul service capability.
2Productivity
If user devices are redirected to a secondary beam with lower signal strength, then network resource allocation is optimized for relay devices, but the signal strength for user devices decreases
Solution Approach 1:
The patent applies parameter changes by selecting a secondary beam whose signal strength differs from the primary beam by less than a predetermined threshold. This ensures that while user devices are redirected to optimize network resource allocation for relay devices, the signal strength degradation is minimal and remains within acceptable parameters, thus maintaining adequate user device connectivity.
3Productivity
If multiple user devices are served by the same beam as a relay device, then beam utilization is maximized, but the relay device consumes excessive network resources providing backhaul services
Solution Approach 1:
The patent extracts user devices from the same beam as the relay device and redirects them to different beams. By taking out user devices from the relay device's beam, the relay device no longer needs to allocate excessive network resources to serve both relay and user device functions simultaneously. This reduces the relay device's network resource consumption while maintaining overall beam utilization across the network.

AI summary
Systems and methods are provided for dynamically allocating SSB beams. It is determined that a relay device and a plurality of user devices are communicating with a cell site by way of a first beam. A quantity of user devices communicating by way of the first beam is then determined. It is determined that this quantity of user devices exceeds a predetermined threshold. A second beam is identified. At least a portion of the user devices is then dynamically reassigned to the second beam.
