First Claim
Patent Images
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.

Abstract
Methods of transmitting a control signal using efficient multiplexing are disclosed. One of the method includes the steps of multiplexing a plurality of 1-bit control signals within a prescribed time-frequency domain by code division multiple access (CDMA) and transmitting the multiplexed control signals, wherein a plurality of the 1-bit control signals include a plurality of the 1-bit control signals for a specific transmitting side. Accordingly, reliability on 1-bit control signal transmission can be enhanced.
