摘要： A method is described herein that enables a Selective-Per-Antenna-Rate-Control (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 rate(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 receiver includes a receiver circuit that decodes multiple signals of interest contained in a composite received signal. The receiver comprises a plurality of successive signal detection stages to detect respective signals contained in the composite received signal. Each detection circuit comprises at least one Generalized RAKE combining circuit and generates a detected signal at an output. Each but the last stage further comprises a signal regeneration circuit that cancels the signal of interest detected by that stage from a stage input signal provided to the next stage such that successive detection of the signals of interest benefits from cumulative cancellation of the previously detected signals.

摘要： A joint detector that improves the performance of receiving a downlink control channel signal for a near-end mobile terminal in the presence of a stronger control channel signal addressed to a far-end mobile terminal sharing the same OVSF, or channelization, code through the use of orthogonal signature sequences. Depending on the specific embodiment, the joint detector may produce the desired bits for the control signal of interest, or may produce detected bits for all control signals sharing the same OVSF code. The joint detector despreads and combines the received code-multiplexed signal, utilizing knowledge of the cross correlations of the set of signature sequences and time-varying channel coefficients to alleviate performance degradation caused by interference from other signals. In various embodiments, the joint detector may be implemented as a modified decorrelating detector, a modified MMSE detector, a modified LS estimator detector, a successive interference-canceling detector, or a jointly hypothesized detector.

摘要： A method and apparatus for code multiplexing one or more control signals onto a shared control channel. According to the present invention, a control signal for transmission from a base station to a mobile station terminal is repeated in each slot of a predetermined time interval. The control signal in each slot is spread using a bit-level spreading sequence, where the bit-level spreading sequence varies from slot to slot according to a predefined sequence-hopping pattern. The spread control signals generated for transmission to each mobile station terminal are then combined and spread using a common channelization code.

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： Signal impairment correlations for multiple signals in a received multipath signal are constructed by fitting parametric models associated with each high-data-rate signal in the multipath against measured impairment correlations. The estimated model fitting parameters are applied to form impairment correlation estimates for all signals. The models comprise a separate impairment covariance matrix scaled by a model fitting parameter for each high-data-rate signal and a noise covariance matrix scaled by a noise element model fitting parameter. The model fitting parameters may be estimated by a least-squares formulation and applied to form impairment correlation estimates for all signals of interest. The resulting impairment correlation estimates may be provided to G-RAKE receivers or joint scaling demodulators to demodulate the signals while suppressing interference from the high-data-rate signals.

摘要： A method and apparatus in a radio receiver for canceling interference from a high power, high data rate signal received in a combined signal that includes a contribution from the high power signal and a contribution from a lower power signal. It is first determined whether the high power signal was correctly received. A CRC checksum may be used to determine whether the high power signal was received with a good reliability. Thereafter, the contribution of the high power signal is removed from the received signal only if the high power signal was correctly received. The contribution of the high power signal may be removed by hard-subtracting the contribution of the high power signal from the received signal if all of the bits of the checksum are correct, and soft-subtracting the contribution of the high power signal from the received signal if most, but not all, of the bits in the checksum are correct.

摘要： According to method and apparatus embodiments taught herein, power control feedback is generated for a control channel signal that is received in conjunction with a reference channel signal based on the reference channel's signal strength or quality, and an estimate of a gain factor relating the control and reference channel signals.
