Analysis and Evaluation of a Practical Downlink Multiuser MIMO Scheduler over LTE Advanced Massive MIMO Systems

A computer-implemented method for enhanced scheduling on a long-term evolution network, the method comprising:

• constructing, by a processor, a ranking for one or more users scheduled for an initial transmission on one or more resource blocks;
• generating, by a processor, an enhanced ranking by applying a hybrid automatic repeat request process that maintains the ranking constructed for the initial transmission in the enhanced ranking for each of the one or more users for which a re-transmission is to be performed, and permits modification of the ranking constructed in the initial transmission for each of the one or more users lacking the retransmission;
• deploying, by the processor, the enhanced ranking into a schedule for the one or more resource blocks being utilized by each of the one or more users;
• and
• optimizing, by the processor, bandwidth usage in the one or more resource blocks by utilizing the schedule.

An enhanced long-term evolution scheduling system, the system comprising:

• a processor and a memory connected to the processor configured to:
• construct a ranking for one or more users scheduled on one or more resource blocks by assigning a precoder to each of the one or more users;
• generate an enhanced ranking that reduces a number of precoder computations on the one or more resource blocks, by only initiating a precoder computation when a precoder computation criterion is met;
• deploy the enhanced ranking into a schedule for the one or more resource blocks being utilized by each of the one or more users;
• and
• optimize bandwidth usage in the one or more resource blocks by utilizing the schedule.
