1. A transmission method, comprising:

  • transmitting, to terminals supported by an enhanced system, a group terminal identifier of the terminals;

    allocating resource blocks (RBs) to at least one data stream transmitted via an enhanced-physical downlink shared channel (E-PDSCH);

    generating control information for each of the RBs;

    allocating the control information for each of the RBs to a resource region for an enhanced-physical downlink control channel (E-PDCCH); and

    performing beamforming, or spatial-multiplexing, or beamforming-based spatial-multiplexing, of the control information for each of the RBs, based on the resource region,wherein a type 1 terminal succeeds in decoding the control information received via the E-PDCCH, and a type 2 terminal does not decode, or fails in decoding, the control information received via the E-PDCCH, and is supported by a different type of system than the type 1 terminal.
