Power control for energy-efficient 5g vran

A method for dynamically allocating physical resource blocks (PRBs) by a PRB controller in a virtualized radio access network (vRAN), comprising:

• determining an average queuing delay for data transmissions associated with downlink and uplink queues for transmitting data between the vRAN and a user device during a first time period;
• detecting that the average queuing delay is greater than a threshold queuing delay;
• and
• adjusting a number of PRBs used for the data transmissions between the vRAN and the user device in response to detecting that the average queuing delay is greater than the threshold queuing delay.

One or more storage devices containing processor readable code for configuring one or more processors, wherein the processor readable code configures the one or more processors to:

• compute an average queuing delay for data transmissions associated with a radio access network during a first time period;
• detect that the average queuing delay is greater than a threshold queuing delay;
• detect that a queue size of a queue used for the data transmissions associated with the radio access network has grown since a prior decision time interval prior to the first time period;
• detect that a number of physical resource blocks should be increased in response to detection that the queue size of the queue has grown since the prior decision time interval prior to the first time period and that the average queuing delay is greater than the threshold queuing delay;
• and
• increase the number of physical resource blocks used for the data transmissions associated with the radio access network.
