FIELD: information technology.
SUBSTANCE: method comprises steps for multiplexing a first control signal with a second control signal in a time slot, the time slot comprising a plurality of orthogonal frequency division multiplexing (OFDM) symbols in the 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, wherein the first control signal is mapped to the plurality of data OFDM symbols after the first control signal is spread by a base sequence in the frequency domain, the RS is mapped to the plurality of RS OFDM symbols, and the second control signal is mapped to at least one of the plurality of RS OFDM symbols, and transmitting the first control signal and the second control signal in said time slot.
EFFECT: high throughput of wireless communication channels.
