Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing load balancing mechanisms in new generation wireless communication systems, such as 5G, face low accuracy due to overlapping frequency domains between cells and the presence of multiple beams within a cell, which affects the accuracy of load balancing operations.
Innovation Solution
A load balancing method and device that receive and process cell available resource information from a target cell, including overlapping situations with other cells in the frequency domain and available resources of beams, to improve the accuracy of load balancing decisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional load balancing mechanism is used, then load balancing operation can be performed, but accuracy is low due to overlapping frequency domains and multiple beams
Solution Approach 1:
The patent segments the load balancing process by introducing detailed cell available resource information including frequency domain overlapping situations and beam-level available resources. This segmentation allows the system to evaluate load balancing accuracy at multiple granularities (cell level and beam level) rather than using a single aggregated view, thereby improving measurement precision while managing complexity through structured information organization
Solution Approach 2:
The patent changes the parameters used for load balancing decisions by incorporating frequency domain overlapping information and beam-specific available resources into the decision-making process. These parameter changes enable more accurate load balancing by considering the actual resource availability affected by frequency overlaps and beam conditions, rather than relying on simplified traditional metrics
2Measurement precision
If cell available resource information including frequency overlapping and beam information is considered, then load balancing accuracy is improved, but information processing complexity increases
Solution Approach 1:
The patent applies preliminary action by having the second node pre-calculate and report cell available resource information including frequency domain overlapping situations and beam-level available resources before the load balancing decision is made. This preliminary preparation of detailed resource information allows the first node to perform accurate load balancing without needing to conduct complex real-time analysis, thereby improving accuracy while managing information processing overhead through advance computation

AI summary
A load balancing method and device, a storage medium and an electronic device are provided. The method includes the following operations. A first node receives cell available resource information of a target cell of a second node from the second node, wherein the cell available resource information includes at least one of: an overlapping situation of the cell with other cells in a frequency domain, an available resource of the cell obtained by performing predetermined processing on an original available resource of the cell according to the overlapping situation of the cell with other cells in the frequency domain, an available resource of one or more beams in the cell, and one or more beam identifiers of the one or more beams in the cell. The first node performs load balancing according to the cell available resource information of the target cell of the second node.
