摘要： A parametric form of G-Rake and chip equalization for closed-loop transmit diversity is provided, that accounts for impairment correlation between transmit antennas. In a closed-loop transmit diversity system, the base station transmits a signal from two or more antennas, using one of a predetermined set of relative phase offsets at one of the antennas. The parametric estimation of the impairment or data covariance is performed by summing terms, including a term for each possible phase offset. The terms are weighted by fitting parameters. The fitting parameters are jointly solved by fitting the impairment or data covariance estimate to a measured impairment or data covariance. In another aspect, a measured impairment covariance is formed by exploiting a special relationship between the pilot channels of the different transmit antennas.

摘要： A method is described herein that enables a Selective-Per-antenna-RateControl (S-PARC) technique to be effectively implemented in a wireless communications network (e.g., HSPDA third generation communications network). In one embodiment, the method enables the S-PARC technique to be implemented in the wireless communications network by enabling a mobile terminal device to generate and transmit a "full" feedback signal to a base station that analyzes the "full" feedback signal and determines which mode and transmission rates(s) are going to be used to transmit data substream(s) from selected transmit antenna(s) to the mobile terminal device. In another embodiment, the method enables the S-PARC technique to be implemented in the wireless communications network by enabling a mobile terminal device to generate and transmit a "reduced" feedback signal to a base station that analyzes the "reduced" feedback signal and determines which mode and transmission rate(s) are going to be used to transmit data substream(s) from selected transmit antenna(s) to the mobile terminal device.

摘要： A method, apparatus, and system perform fast sector identification and base station synchronization. The base station transmits information in primary and secondary control channels to the remote station. The remote station performs synchronization using information in the primary and secondary control channels. A group of identification codes corresponding to the sector is determined using information in the secondary control channel. If this does not result in identification of the sector, an identification code corresponding to the sector is determined from information in the primary control channel. If this does not result in identification of the sector, the sector is identified based on information multiplied with symbols, e.g., pilot symbols, in the primary control channel, without having to decode the BCCH.

摘要： Devices and methods for determining transmission rates based on a virtual diversity receiver (VDR) scheme are disclosed. Performance is improved through determination of appropriate transmission rates, which are determined based on one or more signal to interference plus noise ratios (SINRs). The SINRs are calculated using virtual noise and channel coefficient values obtained as part of the VDR scheme. Utilizing an underlying pilot structure a user device may receive several sets of symbols. These symbols are then used to obtain both real and virtual channel noise power values and channel coefficients. These values and coefficients are then used to determine first and second SINR values indicative of one or more channels in the communication network. These SINR values may correlate to transmission rates (modulation order and/or coding rate). The SINRs may be sent to a base station, or the user device itself may determine one or more transmission rates.

摘要： A receive signal processor jointly detects two or more symbols in a signal-of- interest in the presence of one or more other MIMO signals. The signal-to- interference-plus-noise ratio for each signal-of-interest is determined by computing per- subcarrier signal-to-interference-plus-noise ratios for a plurality of subcarriers allocated to the signals-of- interest, and computing a total signal-to-interference-plus-noise ratio for the subcarriers based on the per-subcarrier signal-to-interference-plus-noise ratios of the subcarriers. A controller determines one or more transmission formats for uplink transmissions based on the signal-to-interference-plus-noise ratios. The process of computing per-subcarrier signal-to-interference-plus-noise ratio reflects the amount of MIMO interference already cancelled or still remaining in the signal arriving at the joint detector.

摘要： A wireless communication device or system generates transmit power control feedback for a received power control channel by determining a command error rate (CER), or by identifying a target signal quality for the power control channel according to a defined signal-quality-to-CER mapping function. Generally, the power control channel does not include error-coded data to use for CER estimation. However, in one embodiment, the channel does include known reference bits that are evaluated for CER estimation, with the estimated CER used to set the signal quality target for inner loop power control. In other embodiments, a computed reception error probability is used to identify a CER estimate according to a defined probability-to-CER mapping function. By way of non-limiting example, these embodiments may be used to provide power control feedback for power control commands transmitted on a Fractional Dedicated Physical Channel in WCDMA systems.

摘要： Acknowledgment signaling in a multiple carrier environment is enabled with a multiple carrier codebook having code words that jointly encode acknowledgment for at least two carriers. For an example embodiment, there is a method in a remote terminal for acknowledgment uplink signaling in a multiple-carrier mode. First, a code word is determined that jointly encodes acknowledgment signaling for at least two carriers from a multiple carrier codebook that is stored in the remote terminal. The multiple carrier codebook includes eight code words that are defined to have a single carrier codebook as a sub-codebook of the multiple carrier codebook, each code word of the eight code words having a length of ten. The multiple carrier codebook achieves a minimum Hamming distance of four among the eight code words. Second, an uplink signaling message that includes the determined code word is transmitted from the remote terminal to a wireless network node.
