摘要： Techniques for transmitting control information in a wireless communication system are described. The system may support acknowledgement (ACK) channels and channel quality indicator (CQI) channels, which may have different target signal-to-noise ratios (SNRs). The ACK and CQI channels from different user equipments (UEs) may be multiplexed on the same resource block. In one design, the transmit power of a CQI channel may be set to achieve a nominal target SNR for CQI when not multiplexed with the ACK channels and may be reduced to achieve a lower target SNR when multiplexed with the ACK channels. In another design, the transmit power of an ACK channel may be set to achieve a nominal target SNR for ACK when not multiplexed with the CQI channels and may be boosted to achieve a higher target SNR when multiplexed with the CQI channels. The CQI channel may randomly hop to mitigate performance degradation.

摘要： Techniques for transmitting data and pilot for control information are described. In one aspect, a user equipment (UE) may spread a reference signal sequence with a first orthogonal sequence to obtain multiple pilot sequences. The UE may then send the multiple pilot sequences on multiple subcarriers in multiple symbol periods, one pilot sequence in each symbol period. The UE may modulate the reference signal sequence with control information (e.g., ACK information) to obtain a modulated sequence. The UE may spread the modulated sequence with a second orthogonal sequence to obtain multiple data sequences. The UE may then send the multiple data sequences on the multiple subcarrier in multiple symbol periods for data. In another aspect, the UE may send multiple pilot sequences on multiple subcarriers in multiple symbol periods separated by at least one symbol period, one pilot sequence in each symbol period.
