METHOD OF TRANSMITTING CONTROL SIGNALS IN WIRELESS COMMUNICATION SYSTEM
First Claim
1. A method of transmitting control signals in a wireless communication system,the control signals being contained in a subframe comprising two consecutive slots, each slot comprising a plurality of orthogonal frequency division multiplexing (OFDM) symbols in time domain, the plurality of OFDM symbols being divided into a plurality of data OFDM symbols and a plurality of reference signal (RS) OFDM symbols, the plurality of data OFDM symbols being used to transmit a first control signal (CQI) and at least one of the plurality of RS OFDM symbols being used to transmit a second control signal, wherein the method comprises:
- mapping the first control signal to the plurality of data OFDM symbols after the first control signal is spread by a base sequence in the frequency domain;
mapping the second control signal to at least one of the plurality of RS OFDM symbols; and
simultaneously transmitting the first control signal and the second control signal in the subframe.
