Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If signaling protocols are used to indicate beam selection information, then beam selection capability is provided, but the protocols are inadequate and cannot provide sufficient signaling information for wireless devices to select beams
Solution Approach 1:
The patent segments beam selection into multiple stages: default beam determination and prioritized beam selection. This segmentation allows the system to handle beam selection in discrete steps, where each stage addresses specific information needs independently, overcoming the limitation of inadequate signaling protocols by breaking down the complex selection process into manageable segments with dedicated determination criteria.
Solution Approach 2:
The patent implements preliminary action by determining default beams before actual data transmission occurs. The wireless device proactively identifies and stores default beam information in advance, so that when beam selection is needed, the device already has pre-determined beam candidates ready, eliminating the need for complex real-time signaling and improving both information availability and selection reliability.
2Device complexity
If beam selection is performed without default beam determination, then signaling complexity is reduced, but data transfer efficiency and signal reliability deteriorate
Solution Approach 1:
The patent implements self-service by enabling the wireless device to autonomously determine its own default beams without requiring complex network signaling. The device uses its own measurements and criteria to select and store default beam information, thereby reducing signaling complexity while maintaining high data transfer efficiency through self-determined beam selection.
Solution Approach 2:
By performing default beam determination in advance as a preliminary action, the system prepares beam selection information before data transmission begins. This preliminary determination stores necessary beam information locally, reducing the need for complex real-time signaling during actual data transfer, thus improving both productivity and reducing device complexity.
3Ease of operation
If beam selection is performed without prioritization criteria, then selection process is simpler, but signal reliability and alignment quality worsen
Solution Approach 1:
The patent applies local quality by introducing prioritization criteria that assign different importance levels to different beams based on their characteristics and suitability for specific procedures. Instead of treating all beams equally, the system evaluates each beam's quality and reliability locally, prioritizing beams that are more suitable for critical procedures, thereby improving signal reliability while maintaining operational simplicity through clear prioritization rules.
Data Source
AI summary
Wireless communications are described. A base station may send control information for scheduling data to be transmitted to the wireless device via a downlink. The control information may comprise one or more indications of wireless resources to be used by the wireless device to receive the data. The wireless device may receive the data based on one or more determinations/conditions, such as satisfying a time offset (e.g., between reception of the downlink information and a scheduled transmission of the data), whether a control resource set is configured to indicate a transmission configuration state, and/or whether the control information indicates a transmission configuration state.
