    摘要: A receiver, or base station, may calculate the signal quality improvement based on a change in a diversity control parameter, for example, a phase difference or a power ratio among two or more antennas, by comparing a received signal power level to an expected power level, assuming no change in fading characteristics at the previous timeslot. This method may increase the amount of information communicated between the base station and the mobile unit, and may reduce feedback response time and/or provide for more efficient feedback for transmit diversity systems.

    摘要: In a cell phone telecommunication system having a macrocell and a small cell coextensive with or adjacent to the macrocell and sharing a common frequency band, interference can occur between a user device operating in the small cell, the local base station operating the user devices in the small cell on one hand and another user device serviced by a main base station for the macrocell. In order to reduce this interference, the shape of the transmission beam from at least one of the user devices or base stations is shaped into a narrow beam steered to be directed at the respective receiving unit. Alternatively, the shape of the transmission beam has a null point and the beam is steered so that its null point is directed toward the affected unit.

    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.

    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.
