Abstract: A method and system for controlling wireless transmission to a user equipment device (UE) while the UE is served on a plurality of carriers each having a respective downlink bandwidth. An example method includes determining that a first carrier of the plurality of carriers has a wider downlink bandwidth than a second carrier of the plurality of carriers. And the method then includes, based at least on the determining, causing transmission to the UE on the first carrier to use a greater quantity of multiple-input-multiple-output (MIMO) layers than transmission to the UE on the second carrier.

Abstract: A method and system for controlling how many carriers to aggregate together for carrier-aggregation service of a UE. A base station could take into account how many MIMO layers a UE would support respectively for each of various candidate quantities of carriers, and the base station could select the candidate quantity of carriers that would result in use of a highest aggregate total number of MIMO layers. Further, the selection could involve mapping UE-reported rank to a quantity of carriers, with the rank being inversely proportional to the selected quantity of carriers. The base station could then configure carrier-aggregation service of the UE with the selected quantity of carriers.

Abstract: A method and system to help control transmission over an air interface from a base station to a served WCD. When the base station has a threshold small quantity of data to transmit over the air to a WCD, the base station will schedule the transmission to occur in a downlink PRB of a special subframe, rather than in a PRB of a regular downlink subframe. As the downlink PRB of the special subframe likely has fewer useable resource elements than the PRB of the regular downlink subframe, this process could help to minimize waste of air interface resources resulting from not making use of resource elements in an allocated PRB.
