Current wireless communication systems face challenges in efficiently managing parameter configurations for periodic communication occasions in multi-user multiple input multiple output (MIMO) operations, leading to interference and suboptimal network performance.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single parameter configuration is used for all communication occasions, then device complexity is reduced, but network performance deteriorates due to inability to optimize for different MIMO operations
Solution Approach 1:
The patent implements dynamic parameter configuration by introducing a parameter switch that selects between SU-MIMO parameter configuration and MU-MIMO parameter configuration based on the communication occasion type. This dynamic switching mechanism allows the system to adapt parameters to different operational modes without maintaining permanently separate configuration sets, thus improving network performance while controlling complexity through a unified switching framework.
Solution Approach 2:
The patent changes physical or chemical state by modifying communication parameters (such as beamforming parameters, resource allocation parameters) based on the MIMO operation type. The parameter switch configuration enables different parameter values to be applied for SU-MIMO versus MU-MIMO operations, optimizing performance for each specific operational context while maintaining a single configurable system.
2Reliability
If separate parameter configurations are used for SU-MIMO and MU-MIMO operations, then network performance is improved, but device complexity increases
Solution Approach 1:
The parameter switch configuration enables dynamic selection between SU-MIMO and MU-MIMO parameter sets based on real-time operational requirements. Rather than maintaining permanently active separate configurations that would increase complexity, the system dynamically activates the appropriate parameter set through a switching mechanism, achieving performance optimization with controlled complexity.
Solution Approach 2:
The parameter switch configuration mechanism serves multiple functions: it selects between different MIMO modes, manages parameter transitions, and coordinates communication occasions. This multi-functional approach consolidates what could be separate complex systems into a unified parameter management framework that handles both SU-MIMO and MU-MIMO operations through a single configurable interface.
3Object-generated harmful factors
If parameter switching is implemented for different MIMO operations, then interference is reduced, but ease of operation deteriorates due to increased configuration management complexity
Solution Approach 1:
The parameter switch configuration enables the system to automatically select and apply the appropriate parameter set (SU-MIMO or MU-MIMO) based on the communication occasion type without requiring manual intervention. The switching mechanism operates autonomously, reducing the operational burden on users while maintaining optimized parameters for different MIMO modes, thus reducing interference without significantly impacting ease of operation.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a parameter switch configuration comprising: a first parameter configuration that indicates a first value of a configuration parameter, the first value corresponding to a first set of communication occasions associated with a single user multiple input multiple output (MIMO) operation; and a second parameter configuration that indicates a second value of the configuration parameter, the second value corresponding to a second set of communication occasions associated with a multiple user MIMO operation. The UE may communicate, based at least in part on the parameter switch configuration, with at least one wireless communication device. Numerous other aspects are described.
