Abstract: When a UE is served by a first RAN and engages in signaling via the first RAN with a second RAN for the second RAN serve the UE with a call (e.g., in a circuit-switched fallback process), the second RAN will determine a speed of movement of the UE and will decide based on the speed of movement whether to provide the UE with a second-RAN traffic channel assignment in addition to providing the UE with an indication of second-RAN coverage in which the call will be served. For instance, if the UE is moving at a threshold high rate of speed, then the entity will provide the UE with a second-RAN traffic channel assignment so as to help expedite the start of the call and to help avoid an issue where the UE may move out of the second-RAN coverage in which the call is to be served.

Abstract: In accordance with the disclosure, when a base station is serving at least a threshold quantity of devices and the base station is allocating at least a threshold quantity of its air-interface resources per unit time, the base station will disable carrier-aggregation service, so as to help minimize or eliminate instances where the base station's carriers would be used as secondary component carriers for carrier-aggregation service and would not support MU-MIMO service. By disabling carrier-aggregation service in that scenario, air-interface resources that might otherwise have been used for secondary-component-carrier transmission without MU-MIMO service may then instead be available for use with MU-MIMO service, which may help to improve spectral efficiency.
