Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, full duplex mode often results in self-interference due to simultaneous transmission and reception over the same frequency resources, which degrades communication quality, especially when beam configurations are not optimized for signal types and device capabilities.
Innovation Solution
A wireless device identifies and utilizes different beam configurations based on signal types, traffic demands, and device capabilities to determine optimal duplexing modes, such as full or half-duplex modes, to minimize self-interference and enhance communication efficiency.

1Productivity
If full duplex mode is used for simultaneous transmission and reception over the same frequency resources, then communication efficiency is improved, but self-interference degrades communication quality
Solution Approach 1:
The patent applies local quality by configuring different beam parameters (such as beam width, direction, and shape) for transmit and receive beams to create spatial separation. The receive beam is configured with specific quality characteristics (narrower width, different direction) to minimize interference from transmit beams, while the transmit beam maintains its own optimization for transmission. This local differentiation of beam properties at different spatial locations and directions enables full duplex operation by reducing self-interference.
Solution Approach 2:
The patent introduces spatial dimensionality through beamforming to resolve the frequency resource conflict. By configuring beams in three-dimensional space (azimuth, elevation, and spatial direction), the system creates separation between transmit and receive signals in the spatial domain. This dimensional approach allows simultaneous transmission and reception on the same frequency resources by directing energy along different spatial paths, effectively adding a spatial dimension to the communication system.
2Reliability
If beam configurations are optimized for signal types and device capabilities, then communication quality is improved, but system complexity increases
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting beam configuration parameters (beam width, direction, spatial direction, shape) based on signal type and device capabilities. Different parameter sets are selected for different scenarios: control channels may use narrower beams for precision, while data channels use wider beams for coverage. Device capabilities such as antenna array size and processing power determine which parameter configurations are applicable, enabling optimized communication quality without requiring all devices to implement all complex configurations.
Solution Approach 2:
The patent segments the beam configuration process into distinct components: transmit beam configuration, receive beam configuration, and duplexing mode determination. Each segment can be independently optimized and managed. The system divides the overall communication task into separate beam management functions, allowing complex optimization to be broken down into manageable segments that can be processed and configured separately based on specific needs.

AI summary
Methods, systems, and devices for wireless communications are described. A wireless device may utilize different beam configurations for different signal types, traffic demand, path loss, capabilities of the wireless device or other wireless devices in the system, and the like. The wireless device also may be capable of determining different duplexing modes, which may be utilized in addition to the different beam configurations. The duplexing mode may be based on received measurement reports (e.g., from one or more reference signals) or in some instances, the duplexing mode may be determined by another node (e.g., a core network node, a base station) and transmitted to the wireless device.
