1. A method performed by a first user equipment (UE) for providing a secondary cell to one or more user equipments (UEs) in a base station-user equipment dual connectivity (BUDC) group, the method comprising:

receiving, at the first UE and from a base station serving as a primary cell to the first UE and the one or more UEs in the BUDC, configuration information for the first UE to serve as a secondary cell-user equipment (SC-UE) that provides the secondary cell for the one or more UEs in the BUDC group;

providing, by the first UE and to a second UE connected to the base station, access to the secondary cell for a secondary connection by admitting the second UE to the BUDC group;

scheduling, for the second UE, resources of an air interface for communication in the secondary cell provided by the first UE for the one or more UEs in the BUDC group; and

communicating data with the second UE in the BUDC group using the resources of the air interface that are scheduled for communication in the secondary cell.
