Claim:
1. An Access Point (AP), comprising: a Massive Multiple Input Multiple Output (M-MIMO) antenna array comprising a plurality of antenna elements; and a processor configured to control a first subset of the plurality of antenna elements of the M-MIMO antenna array to broadcast a control signal on a first frequency band using a non-M-MIMO radio access technology (RAT), and further configured to control a second subset of the plurality of antenna elements of the M-MIMO antenna array to beamform one or more data streams on a second frequency band to a user device using a M-MIMO RAT, wherein the processor is further configured to: generate one or more symbol streams intended for the user device; determine a transmit precoder matrix; and pre-code the one or more symbol streams using the transmit precoder matrix to generate the one or more data streams, wherein the control signal broadcast on the first frequency band using the non-M-MIMO RAT includes control information for the one or more data streams beamformed on the second frequency band to the user device using the M-MIMO RAT.
