Methods, apparatus, and systems for using multiple antennas located in Citizens Broadcast Radio Service Devices (CBSDs) to communicate with a user equipment device. An exemplary method embodiment includes the steps of: (i) receiving by a macro base station a first set of data to be transmitted to a user equipment device (UE), (iii) dividing by the macro base station said first set of data into a plurality of N data blocks, and (iv) communicating by the macro base station to each of a plurality of different Citizens Broadband Radio Service Devices (CBSDs) one or more different ones of said plurality of N data blocks; and (v) operating the plurality of CBSDs to transmit the one or more data blocks which they receive from the macro base station to the UE. In various embodiments, the macro base station also transmits one or more of the N data blocks to the UE.
