Beam Selection via Association Mapping for 5G Latency Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G systems, receiving devices face high complexity and latency in data reception due to the need to separately measure multiple beams sent by the sending device for signal quality, which requires significant measurement time.
Innovation Solution
The proposed solution involves a beam selection method where the receiving device receives beam associating information from the sending device, allowing it to quickly select a beam for reception based on the association between a first beam and multiple second beams, thereby reducing the number of signal quality measurements needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the receiving device separately performs measurements on multiple beams sent by the sending device to identify the beam with good signal quality, then the beam selection accuracy is improved, but the measurement time increases, resulting in high complexity and latency of data reception
Solution Approach 1:
The patent applies preliminary action by having the receiving device perform measurements on multiple beams in advance before actual data reception. The device stores the measurement results and uses them to quickly select an appropriate beam when data reception is needed, avoiding the need to perform measurements again at the time of data reception. This resolves the contradiction by separating the measurement process from the data reception process, maintaining accuracy while reducing time loss.
2Measurement precision
If the receiving device separately performs measurements on multiple beams sent by the sending device, then the beam selection accuracy is improved, but the complexity of data reception increases
Solution Approach 1:
The patent reduces complexity by performing beam measurements in advance and storing the results. When data reception occurs, the device simply retrieves pre-stored measurement results to select a beam, rather than performing complex measurement and selection processes at the moment of data reception. This separates the complex measurement task from the data reception workflow.
3Measurement precision
If the receiving device separately performs measurements on multiple beams sent by the sending device, then the beam selection accuracy is improved, but the latency of data reception increases
Solution Approach 1:
The patent applies preliminary action by performing beam measurements before data reception and storing the results for later use. When data reception is needed, the device can immediately select a beam based on pre-stored measurement results without waiting to perform new measurements, thereby maintaining accurate beam selection while significantly reducing data reception latency.

AI summary
Embodiments of the present invention relate to the field of communications, and provide a beam selection method, apparatus and system. The method comprises: a receiving device receives at least one set of beam associating information sent by a sending device, each set of the beam associating information including an association relation between a first beam and at least one second beam; and selects, according to the at least one set of beam associating information, a beam to be received among beams sent by the sending device, i.e., the receiving device may quickly select, according to the association relation between the first beam and the second beam sent by the sending device, a beam to be received among beams sent by the sending device, so that the number of steps or measurements performed for the signal quality of beams during data receiving process are reduced, thereby reducing the time spent on beam measurements, accelerating the process of beam measurement and selection of the receiving device, simplifying the complexity of data receiving, and lowering the latency of data receiving.
