Method and apparatus for transmitting an ACK/NACK signal in a wireless communication system

A method performed by a mobile station, comprising:

• determining a sequence corresponding to one of acknowledge (ACK) information and non-acknowledge (NACK) information;
• and
• mapping the sequence onto a transmission channel for later transmission from the mobile station to a base station, wherein, the transmission channel is allocated with at least a part of three feedback mini-tiles (FMTs), each of the FMTs comprising two subcarriers contiguous in a frequency domain by six orthogonal frequency division multiplexing (OFDM) symbols contiguous in a time domain and the three FMTs being discontinuous in the frequency domain.

A non-transitory computer readable medium encoded with computer executable instructions, which when accessed, causes a mobile station to perform operations comprising:

• determining a sequence corresponding to one of acknowledge (ACK) information and non-acknowledge (NACK) information;
• and
• mapping the sequence onto a transmission channel for later transmission from the mobile station to a base station, wherein, the transmission channel is allocated with at least a part of three feedback mini-tiles (FMTs), each of the FMTs comprising two subcarriers contiguous in a frequency domain by six orthogonal frequency division multiplexing (OFDM) symbols contiguous in a time domain and the three FMTs being discontinuous in the frequency domain.

A mobile station, comprising:

• A processor;
• A transceiver, coupled to the processor, to determine a sequence corresponding to one of ACK information and NACK information provided by the processor and to map the sequence onto a transmission channel for later transmission from the mobile station to a base station,
• wherein, the transmission channel is allocated with at least a part of three feedback mini-tiles (FMTs), each of the FMTs comprising two subcarriers contiguous in a frequency domain by six orthogonal frequency division multiplexing (OFDM) symbols contiguous in a time domain and the three FMTs being discontinuous in the frequency domain.
