19. A method for satellite communication, the method comprising:
generating a macro cell downlink transmit (Tx) beam to cover a plurality of micro cells in a macro field of view, each of the plurality of micro cells being associated with a respective individual micro cell uplink receive (Rx) beam;
determining a user equipment (UE) access request from a UE located in a given one of the plurality of micro cells, the access request having been sent over the micro cell uplink Rx beam associated with the given one of the plurality of micro cells; and
communicating, in response to the UE access request, the macro cell downlink Tx beam as an active downlink Tx beam, only to the given one of the plurality of micro cells associated with the UE access request.
