If there is no such a URLLC-demanding UE present in the local service area, cell configuration over the local service area may follow the approach provisioned and used to support MBB and non-URLLC MTC services as in current LTE networks for example.
If there is such a URLLC demanding UE in the local service area then the following possibilities may be considered.
HAP, as provided by a subset of local cells within the cell cluster, may be characterized by some preconfigured pattern of collective or aggregated resource allocation of at least common cell-specific reference signals and control channels (such like SS, BCH, PCH and RACH) across the individual cells of the subset which are made available to serve a UE (recognizable by UE).
