    Abstract: A system including a first preamble generator module configured to generate a first preamble for a first packet, which is a single-user packet. The first preamble includes a first short training field, a first long training field, a first signal field, and a second signal field. A second preamble generator module generates a second preamble for a second packet, which is a multi-user packet formatted as a multi-user packet or a single-user packet formatted as a multi-user packet. The second preamble is longer than the first preamble. The second preamble includes a second short training field, a second long training field, a third signal field, and a fourth signal field. A modulation module modulates at least one of the first signal field and the second signal field of the first preamble differently than at least one of the third signal field and the fourth signal field of the second preamble.

    Abstract: Machine-readable media, methods, apparatus and system for transmitting ACK/NACK signal in a wireless communication system are described. In some embodiments, a sequence corresponding to one of acknowledge (ACK) information and non-acknowledge (NACK) information may be determined. Then, the sequence may be mapped onto a transmission channel for later transmission from the mobile station to a base station. In some embodiments, the transmission channel may be allocated with at least a part of three feedback mini-tiles (FMTs), wherein each of the FMTs comprises two subcarriers contiguous in frequency domain by six orthogonal frequency division multiplexing (OFDM) symbols contiguous in time domain and the three FMTs being discontinuous in frequency domain.

    Abstract: A method is disclosed for transmitting channel quality reports periodically from a secondary station to a primary station, wherein transmission of a control channel is carried out discontinuously with a predetermined periodic transmission phase, and wherein said method comprises the following steps. Scheduling the transmission of a transmission sequence of channel quality reports of at least a first type and a second type according to a predetermined pattern. Estimating the number of channel quality reports of the second type scheduled during the transmission phases of a predetermined time window. Amending the transmission sequence by replacing at least one channel quality report scheduled to be of the first type with a channel quality report of the second type if the number of second type channel quality reports scheduled during the transmission phases of the predetermined time window is below a predetermined threshold. Transmitting the amended sequence to the primary station.
