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： 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.
