1. A method of transmitting a control signal, the method comprising:

  • multiplexing a plurality of 1-bit control signals within a single prescribed time-frequency domain by a code division multiple access (CDMA) scheme, wherein the plurality of 1-bit control signals multiplexed within the single prescribed time-frequency domain are distinguished by orthogonal or pseudo-orthogonal codes used for multiplexing each of the plurality of 1-bit control signals;

    repeating multiplexing of the plurality of multiplexed control signals in different frequency domains; and

    transmitting the repeatedly multiplexed control signals.
