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 mobile communications method, device, and system for adjusting a phase parameter in a diversity signal, based at least in part on phase feedback from a base station. While in uplink communication with a base station, a mobile device may receive a phase feedback signal from the base station. The mobile device may calculate a modified value of a phase parameter based on the phase feedback signal in order to transmit diversity signals with a gradual change in phase difference. The modified value may be between a phase parameter value indicated by the base station's phase feedback signal and a phase parameter value initially transmitted by the mobile device.

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： Communication is performed for a first communication device having a set of antenna elements. A quality-indication signal is received from a second communication device (e.g., a basestation). A complex weighting is calculated based on the quality-indication signal. A pre-transmission signal is modified based on the complex weighting to produce a set of modified-pre-transmission signals. Each modified pre-transmission signal from the set of modified-pre-transmission signals is uniquely associated with an antenna element from the set of antenna elements. The set of modified-pre-transmission signals is sent from the set of antenna elements to produce a transmitted signal. The complex weighting is associated with a total power of the transmitted power and at least one from a phase rotation and a power ratio associated with each antenna element from the set of antenna elements. For example, in CDMA based systems, a fast feedback from the basestation—the power control indication—can be used by a subscriber communication device for this transmission diversity method in such a way that provides the desired signal quality at the basestation, without necessarily responding to fading nulls by mobile unit power output increase, but rather, by manipulating the weights of the mobile transmitter antenna array. Thus, a significant reduction in average and peak mobile power level is achieved, enhancing network capacity, battery life, and radiation hazards.
