1. A method for scheduling cellular data transmissions, the method comprising:
determining a plurality of channel quality indicator (CQI) values that correspond to a plurality of user equipment (UE) communicating with a base station (BS);
creating a scheduling matrix comprising a plurality of elements storing a plurality of data transfer rates based on the determined plurality of CQI values, wherein:
a first dimension of the scheduling matrix corresponds to a plurality of physical resource blocks (PRBs); and
a second dimension of the scheduling matrix corresponds to the plurality of UE;
removing an entry from the scheduling matrix for a UE that corresponds to a carrier component of a plurality of carrier components that is ineligible for use by the UE due to insufficient signal strength of the carrier component for the UE;
after removing the entry from the scheduling matrix for the UE that correspond to the carrier component of the plurality of carrier components that is ineligible for use by the UE due to insufficient signal strength of the carrier component for the UE, normalizing elements of the plurality of elements of the scheduling matrix by modifying the plurality of data transfer rates based on a plurality of average data transfer rates; and
performing data transfers with the plurality of UE by the BS based on the normalized scheduling matrix that has the entry removed.
