Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in efficiently managing sidelink beam resources, leading to interference, latency, and suboptimal resource utilization in sidelink communications, particularly in 5G New Radio (NR) networks.
Innovation Solution
The implementation of sidelink reference signal blocks (S-RSBs) with reduced size and optimized beam management signals, allowing for sensing-based resource selection and transmission in sidelink resource pools, which reduces interference and conserves signaling resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional beam management signals are used in sidelink communications, then beam management functionality is provided, but signaling resources are consumed excessively and interference increases
Solution Approach 1:
The patent segments the beam management signal into a dedicated reference signal block (S-RSB) structure separated from traditional sidelink signals. This segmentation allows beam management functions to be isolated in specific time-frequency resources, preventing interference with other sidelink communications while maintaining dedicated beam management capability.
Solution Approach 2:
The patent extracts beam management functionality from the general sidelink communication framework and places it into a dedicated reference signal block structure. This extraction removes beam management signals from the mixed signal environment, allowing for more efficient resource utilization and reduced interference with other sidelink data transmissions.
2Reliability
If traditional beam management signals are transmitted continuously, then beam management is maintained, but latency increases and resource utilization decreases
Solution Approach 1:
The patent implements periodic transmission of reference signal blocks for beam management rather than continuous transmission. The gNB can configure the periodicity of S-RSB transmissions, allowing beam management to be maintained at appropriate intervals while reducing overall signaling overhead and latency in the sidelink communication system.
3Adaptability or versatility
If beam management signals use standard size and structure, then compatibility is maintained, but interference with other sidelink signals increases
Solution Approach 1:
The patent segments the time-frequency resource space by introducing dedicated reference signal blocks that are separated from traditional sidelink communication signals. This segmentation creates protected zones for beam management signals, preventing them from interfering with other sidelink data transmissions while maintaining compatibility through standardized S-RSB structure.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may perform sensing in a sidelink resource pool. The UE may select, based at least in part on the sensing, one or more sidelink resources for one or more sidelink beam management blocks, where each sidelink beam management block includes at least one reference signal and sidelink control information. The UE may transmit the one or more sidelink beam management blocks in a sidelink beam management block burst using the one or more sidelink resources. Numerous other aspects are described.
