Optimized radio resource management for 5g network slicing

A method for optimizing radio resource allocation for 5G-slicing environment in a wireless network, comprising:

• allocating, by at least one of downlink (DL) scheduler and uplink (UL) scheduler, radio resources to each protocol data unit (PDU) session according to a radio resource management (RRM) policy comprising the following rules for each RRM policy ratio instance n, n=1, 2, . . . , N:
• i) providing a dedicated resource allocation in which an aggregate of specified Xn % of total available radio resources AvailRBTOT is allocated to all PDU sessions belonging to slices in a member list Ln;
• ii) providing a prioritized resource allocation in which an aggregate of specified (Yn-Xn) % of the total available radio resources AvailRBTOT is allocated to PDU sessions belonging to slices in the member list Ln;
• iii) providing a shared resource allocation in which any remaining radio resources are shared by all PDU sessions, including PDU sessions from slices that have already been allocated radio resources, whereby aggregate radio resources allocated to PDU sessions in the member list L,, do not exceed specified Z, % of the total available radio resources AvailRBTOT for each n=0, 1, 2 . . . , N;
• and
• iv) providing, for signaling radio bearers (SRBs) and Medium Access Control elements (MAC-CEs), a separate SRB policy instance with a member list Ln having a single entry, SRB slice, wherein the SRB slice contains all SRB and MAC-CE traffic in a given cell of the wireless network.
