Beam Cluster Reception Control for Lower Beamforming Overhead
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems that use beam forming for transmission and/or reception, the system overhead related to training, beam tracking, and beam switching is relatively high.
Innovation Solution
A method that involves receiving beam cluster information from a beam forming access point, which defines multiple beam clusters and provides beam identification information for each beam. This information is used to control the processing of received beams, including determining receive processing information to optimize the reception of beams within a cluster.

Engineering Contradiction Analysis
1Reliability
If beam forming is used for communication between access point and user equipment, then communication performance is improved, but system overhead relating to training, beam tracking and beam switching becomes relatively high
Solution Approach 1:
The patent segments the beam management process by introducing beam cluster information that groups multiple beams together. Instead of treating each beam individually for training and tracking, the system divides beams into clusters where a single beam cluster reference signal can represent multiple beams, thereby reducing the quantity of training and tracking operations required.
Solution Approach 2:
The patent uses beam cluster reference signals as simplified copies or representations of multiple individual beam reference signals. By transmitting a single beam cluster reference signal that represents multiple beams, the system reduces the overhead of transmitting and processing individual beam reference signals while maintaining the essential functionality for beam management.
2Measurement precision
If individual beam processing is performed for each beam, then beam accuracy is improved, but processing complexity and overhead increase
Solution Approach 1:
The patent merges the processing of multiple individual beams by introducing beam cluster information that allows a single receive processing configuration to handle multiple beams within a cluster. This combining approach maintains beam accuracy for each individual beam while reducing the overall processing complexity by treating clustered beams as a group rather than as separate entities.
