Systems and methods described herein provide optimized resource management to meet Ultra-Reliable Low-Latency Communications (URLLC) service requirements in Radio Access Networks (RANs), such as Fifth Generation New Radio (5G-NR) RANs. A network device stores resource management policy options for implementing communication sessions for a URLLC service level and determines that the URLLC service level is required for a communication session requested by a user equipment (UE) device. The network device selects one of the resource management policy options for the communication session based on a number of antennas used by an access station supporting the communication session and one of: an estimated available bandwidth for the access station or a transmission delay for processing a packet in the communication session. The network device sends, to the access station, the selected one of the different resource management policy options.
