11. A system for dynamically allocating radio resources across a set of virtualized radio access points (vRAPs) in a virtual radio access network (vRAN), the system comprising:
a radio resource controller that is configured to:
execute a mapping policy that maps contextual information collected across all vRAPs that share a common carrier bandwidth of a physical radio access point into an allocation of vRAN slices to the vRAPs, wherein each vRAN slice comprises allocated computing resources and an allocated bandwidth part (BWP) of the common carrier bandwidth, the BWPs being orthogonal across the vRAN slices,
compute a set of BWP vectors containing BWPs eligible for each vRAP such that the eligible BWPs for individual vRAPs across all vectors maximize a distance function, and
notify the vRAPs of their individual BWP allocations.
