Abstract:
1. A method of operating a scheduler to schedule up-link transmissions of a first plurality of terminals of a wireless communication system into a second plurality of groups, wherein each group comprises terminals intended for simultaneous up-link transmission during a respective period of time, comprising: receiving a respective transmission from each of the first plurality of terminals; calculating a subset metric for each subset in a third plurality of subsets of the first plurality of terminals, wherein a size of each subset is less than or equal to the second plurality, and wherein the subset metric is calculated based on the transmissions received from the terminals of the subset and is indicative of a simultaneous transmission suitability measure for the terminals of the subset; forming a fourth plurality of subsets from the third plurality of subsets; processing each subset in the fourth plurality of subsets in subset metric order, starting with a subset having a subset metric indicating a least suitability of simultaneous transmission among the subsets of the fourth plurality of subsets, by: scheduling each terminal of the subset that is not already scheduled in a group, in a group of the second plurality of groups that does not comprise another terminal of the subset; transmitting, to each of the scheduled terminals, an information indicative of the respective period of time during which the scheduled terminal is intended to transmit.
