Systems and methods for scheduling wireless data transmissions

A system for scheduling wireless data transmissions comprising:

• at least one computer processor;
• and
• at least one memory coupled to the at least one computer processor, the at least one memory having computer-executable instructions stored thereon that, when executed by the at least one computer processor, cause the at least one computer processor to perform:
• maintaining in memory an average data rate for each of a plurality of user equipment devices (UEs) that each have data to transfer on one of two overlapping frequency bands including a first frequency band and a second frequency band, the UEs having data to transfer on the first frequency band belonging to a first group of UEs and the UEs having data to transfer on the second frequency band belonging to a second group of UEs;
• determining, at a scheduling time t, for each of the UEs, a metric for the UE that is a ratio of a downlink channel quality indicator for the UE to the average data rate of the UE at scheduling time t;
• allocating at scheduling time t, physical resource blocks (PRBs) to UEs belonging to the first group up to a maximum number of PRBs available for the first group, giving higher priority for PRB allocation to UEs belonging to the first group that have a larger metric than other UEs belonging to the first group;
• and
• allocating at scheduling time t, PRBs to UEs belonging to the second group up to a maximum number of PRBs available for the second group, giving higher priority for PRB allocation to UEs belonging to the second group that have a larger metric than other UEs belonging to the second group.

A non-transitory computer-readable storage medium having computer-executable instructions stored thereon that, when executed by at least one processor, cause the at least one processor to perform:

• maintaining in memory an average data rate for each of a plurality of user equipment devices (UEs) that each have data to transfer on one of two overlapping frequency bands including a first frequency band and a second frequency band, the UEs having data to transfer on the first frequency band belonging to a first group of UEs and the UEs having data to transfer on the second frequency band belonging to a second group of UEs;
• determining, at a scheduling time t, for each of the UEs, a metric for the UE that is a ratio of a downlink channel quality indicator for the UE to the average data rate of the UE at scheduling time t;
• allocating at scheduling time t, physical resource blocks (PRBs) to UEs belonging to the first group up to a maximum number of PRBs available for the first group, giving higher priority for PRB allocation to UEs belonging to the first group that have a larger metric than other UEs belonging to the first group;
• and
• allocating at scheduling time t, PRBs to UEs belonging to the second group up to a maximum number of PRBs available for the second group, giving higher priority for PRB allocation to UEs belonging to the second group that have a larger metric than other UEs belonging to the second group.
