6. IMPLEMENTATION AND STANDARDIZATION
The implementation of novel resource allocation techniques
in 6G Sidelink V2X networks requires collaboration
between industry stakeholders and standardization bodies.
Standardization efforts must define interoperable interfaces Figure 11 – Spectrum Allocation over time (SPS-DSA)

dynamically allocated among vehicles combining DSA with
SPS. The allocation is more adaptive to changing conditions.
The SPS-DSA scheme, which incorporates dynamic
spectrum access using optimization, performs better in
terms of utility and provides smoother spectrum allocation
compared to the traditional SPS scheme. This dynamic
approach adapts better to varying network conditions and
vehicle demands, leading to more efficient and effective
