    摘要: Embodiments of the present invention describe methods for increasing the amount of information available to a mobile transmit diversity transmitter during soft handoff. According to embodiments of the invention, a transmit diversity transmitter may determine substantially when it is within the range of at least two receivers. In such situations, the transmitter may use the power control signals from more than one receiver, for example, from the two most dominant receivers in order to focus the beamforming accordingly.

    摘要: Modifying a signal according to a diversity parameter adjustment includes accessing scan parameter values, where a scan parameter describes a scan process. The scan parameter values include diversity parameter vectors, where a diversity parameter vector has a diversity parameter value for each of one or more diversity parameters. The scan process is performed by repeating the following for each diversity parameter vector: modifying a signal according to the diversity parameter values of the diversity parameter vector, where the signal is transmitted from a modifying communication device to a feedback communication device; and receiving a feedback signal reflecting feedback information describing the signal as received by the feedback communication device.
