Abstract
When a base station is using multiple-input multiple-output (MIMO) communication defining multiple layers of communication to serve a user equipment device (UE) over an uplink channel, and the base station detects that its backhaul connection is threshold highly congested, the base station will responsively reduce the number of communication layers used to serve the UE over the uplink channel. In some examples, the base station could reduce the number of communication layers to a single layer, thereby transitioning from serving the UE using uplink MIMO communication to serving the UE using uplink single-input single-output (SISO) communication.
