Abstract: In an example method, a donor base station determines that an air interface, over which the donor base station serves a relay-UE and plurality of second UEs, is threshold highly congested and that a relay base station is serving a threshold high number of first UEs. The relay base station is coupled to a relay-UE that provides wireless connectivity for the relay base station and that is served by the donor base station. Responsive to at least the determining that the air interface is threshold highly congested and that the relay base station is serving a threshold high number of first UEs, the donor base station (i) selects one or more of the plurality of second UEs and (ii) hands over the selected one or more second UEs to another base station other than the donor base station.

Abstract: When a base station groups a given user equipment device (UE) together with one or more other UEs for multi-user multiple-input-multiple-output (MU-MIMO) service, the base station will predict a level of RF correlation between the given UE and the one or more other UEs of the group (e.g., based angular separation between beam direction of the UE and beam direction of each of the one or more other UEs). And the base station will use that predicted level of RF correlation as a basis to adjust a modulation and coding scheme (MCS) that the base station and the given UE will use for data communication with each other, so as to help improve data communication between the base station and the given UE in the presence of the predicted RF correlation.
