Beamformed Pre-Reservation Signaling for Sidelink Conflicts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in efficiently managing resource conflicts and interference in sidelink communications, particularly in device-to-device interactions, which can lead to suboptimal utilization of available resources.
Innovation Solution
The implementation of beamforming information for transmitting pre-reservation signals that indicate sets of non-preferred resources associated with data transmissions, allowing UEs to proactively avoid resource conflicts and optimize sidelink communications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional resource allocation methods are used in sidelink communications, then resource conflicts and interference occur, but resource utilization efficiency deteriorates
Solution Approach 1:
The patent applies preliminary action by transmitting pre-reservation signals before actual data transmissions occur. These pre-reservation signals indicate non-preferred resources in advance, allowing receiving UEs to proactively avoid resource conflicts before they happen. This advance notification mechanism enables UEs to select alternative resources proactively, thereby reducing interference and improving resource allocation efficiency in sidelink communications.
2Reliability
If beamforming information is used for pre-reservation signaling, then resource conflicts are reduced, but system complexity increases
Solution Approach 1:
The patent applies local quality by implementing beamforming-specific processing only where needed - specifically in the transmission and reception of pre-reservation signals. The beamforming information is incorporated into the SCI (Sidelink Control Information) messages, allowing targeted optimization for directional communications without requiring complete system redesign. This localized approach manages complexity while achieving improved resource allocation through directional awareness.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a transmitter user equipment (UE) may identify beamforming information for transmitting a pre-reservation signal that indicates a set of non-preferred resources associated with a data transmission. The UE may transmit, to a receiver UE in accordance with the beamforming information, the pre-reservation signal that indicates the set of non-preferred resources associated with the data transmission. Numerous other aspects are described.
