    摘要: Techniques for transmitting beacon signals to assist user equipments (UEs) perform cell search and techniques for detecting for beacon signals are described. In an aspect, cells may be assigned beacon patterns defined based on orthogonal grouping of subcarriers. U subcarriers usable for beacon may be arranged into G orthogonal groups, with each group including S subcarriers. different beacon patterns may be defined based on the G groups of S subcarriers. In another aspect, the cells may transmit their beacon signals at configurable transmit power levels, which may be determined based on target beacon detection performance. In yet another aspect, a UE may perform overlapping DFTs in order to capture more received power when symbol timing at the UE is not aligned with symbol timing of cells being detected. In yet another aspect, the UE may perform beacon detection with maximal likelihood decoding.

    摘要: A power spectral density of a pilot symbol and a data symbol is controlled for an uplink transmission by a mobile station in a wireless network by determining a power spectral density of at least one of the data symbol and the pilot symbol based on a peak-to-average ratio (PAR) of at least one of the data symbol and the pilot symbol. A power spectral density of at least one of the data symbol and the pilot symbol is then dynamically adjusted based on a difference between the PAR of the data symbol and a PAR of the pilot symbol. Changes in the power spectral densities of the pilot symbol and the data symbol are signaled to a receiving side of the uplink transmission. If acceptable by the receiving side, the pilot symbol and the data symbol are transmitted to the receiving side of the uplink transmission.

    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.
