    摘要: A method for modifying a signal transmitted from a mobile communication device comprising by perturbing a transmit diversity parameter from its nominal value by modulating the parameter with respect to the nominal value in a first direction for a first feedback interval and then in a second direction for a second feedback interval, receiving a feedback signal including feedback information relating to the perturbed signal as received at a feedback device, and based at least on the feedback information, adjusting the nominal value of the transmit diversity parameter by increasing, decreasing, or preserving the nominal value.

    摘要: A device, system, and method for providing a transmit diversity device have a first antenna and a second antenna. The first antenna may have a first power transmission gain pattern, which may be non-uniform in a reference plane. The second antenna may have a second power transmission gain pattern, which may be non-uniform in a reference plane. The first and second antennae may be arranged with respect to each other such that a minimum power region of the first gain pattern overlaps a maximum power region of the second gain pattern in the reference plane. The transmit diversity device may also have a processor to receive a feedback parameter from a feedback device. The processor may produce a different transmit diversity parameter based on the feedback parameter for each of a first and second signals to be transmitted on the first and second antennae, respectively.

    摘要: Embodiments of the present invention extend the benefits of mobile transmit diversity to the initialization phase of communication with a base station over a random access channel. According to a method of the invention, the transmitter may attempt to initiate communication with a receiver by varying a transmit diversity parameter, for example, phase difference, in addition to or instead of varying power settings.

    摘要: A method and system for improving closed loop feedback in transmit diversity communication. In one embodiment of the invention, a predetermined variation of one or more transmit diversity parameters is performed at the transmit diversity transmitter. The receiver compares the transmit diversity parameter values of the received signals to the predetermined variation and transmits to the transmitter a value of a transmit diversity correction parameter. The transmitter may use this correction value to modify the transmit diversity parameter in a subsequent transmission.

    摘要: A method, apparatus, and system for transmitting and controlling uplink diversity signals in a mobile communication device. While in a soft handoff situation, a mobile communications device may receive a phase feedback signal from a non-serving base station. The mobile device may calculate a modified phase parameter based on the phase feedback signal from the non-serving base station in order to minimize interference with the non-serving base station, for example, by calculating a modified value of a phase difference in a direction opposite to the direction desired by the non-serving base station. In some embodiments of the invention, the mobile device may determine whether to calculate the modified phase parameter in a direction opposite to the direction indicated by the phase feedback signal of the non-serving base station based on a comparison of power feedback signals received from the non-serving and serving base stations.
