Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in enhancing the throughput and reliability of sidelink communications, particularly in scenarios involving multiple users and dynamic environmental conditions, due to limitations in beam management and resource allocation.
Innovation Solution
Implementing flexible beam management techniques that allow user equipment (UE) to indicate transmission beam information to the base station, enabling the scheduling of sidelink transmissions and updating beam configurations based on mobility and environmental factors, while supporting multi-beam and multi-panel operations to improve sidelink communication efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If beamformed sidelink transmissions are implemented, then throughput and reliability are improved, but device complexity increases due to multi-beam and multi-panel operations
Solution Approach 1:
The patent changes the parameter of beam management from static to dynamic by allowing UEs to update transmission beam information based on mobility and environmental factors. The base station schedules sidelink transmissions with updated beam configurations, enabling adaptation to changing conditions while maintaining reliable communication.
Solution Approach 2:
The patent implements dynamic beam management where transmission beam information is not fixed but can be updated based on current conditions. The base station receives beam information from UEs and schedules transmissions accordingly, allowing the system to adapt dynamically to mobility and environmental changes, thereby improving reliability without requiring overly complex static configurations.
2Adaptability or versatility
If flexible beam management is implemented, then adaptability to environmental factors is improved, but signaling overhead increases due to continuous beam information updates
Solution Approach 1:
The patent applies partial action by having UEs indicate transmission beam information only when changes occur or at scheduled intervals, rather than continuously reporting all beam parameters. The base station uses this partial information to schedule sidelink transmissions effectively, reducing signaling overhead while maintaining adaptability to environmental factors.
3Productivity
If simultaneous sidelink transmissions are supported, then productivity is improved, but interference management becomes more difficult
Solution Approach 1:
The patent segments the sidelink transmission resources by assigning different time-frequency resources to different transmissions. The base station schedules multiple sidelink transmissions with distinct resource allocations, allowing simultaneous transmissions while managing interference through resource separation rather than complex coordination between UEs.

AI summary
Methods, systems, and devices for wireless communications are described. A device may be configured to support multi-beam, or multi-panel operations, or both which may allow multiple sidelink transmissions to occur simultaneously. In some cases, flexible beam-management for the beamformed sidelink communications is implemented to manage the beams. A transmitting UE may indicate transmission beam information to the base station that the base station may use to schedule sidelink transmissions as part of a beam management procedure. The beam management procedure may allow a transmitting UE to update transmission beam information based on the mobility of the sidelink UEs and other environmental factors. In some cases, beam management includes a beam training procedure that may be implemented to refine the sidelink beams, where support for multi-panel and multi-beam operation may allow for multiple beams to be trained simultaneously.
