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.

A method of controlling wireless transmission to a user equipment device (UE), the method comprising, while the UE is served on a plurality of carriers each having a respective downlink bandwidth:
- determining that a first carrier of the plurality of carriers has a wider downlink bandwidth than a second carrier of the plurality of carriers;
- 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.
A computing system comprising:
- a processing unit;
- non-transitory data storage;
- and
- program instructions stored in the non-transitory data storage and executable by the processing unit to carry out operations while a user equipment device (UE) is served on a plurality of carriers each having a respective downlink bandwidth, the operations including:
- determining that a first carrier of the plurality of carriers has a wider downlink bandwidth than a second carrier of the plurality of carriers;
- 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.
An access node configured to control wireless transmission to a user equipment device (UE), the access node comprising:
- a wireless communication interface including an antenna structure through which the access node engages in air-interface communication;
- a controller configured to carry out operations when the UE is served on a plurality of carriers each having a respective downlink bandwidth and wherein the UE is served on at least one of the carriers by the access node, the operations including:
- determining that a first carrier of the plurality of carriers has a wider downlink bandwidth than a second carrier of the plurality of carriers;
- 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.
