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： 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 transmit diversity weighting to produce a set of modified-pre-transmission signals, wherein the modifications are symmetric by making approximately half the magnitude of the transmit diversity modification to one signal in a first direction, and approximately half the magnitude of the transmit diversity modification to the other signal in a second direction, opposite the first direction. 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.

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 signal is modified according to a current diversity parameter adjustment, and is transmitted from a modifying communication device to a feedback communication device. A feedback signal reflecting feedback information describing the signal as received by the feedback communication device is received. The feedback signal comprises frames, and a frame comprises slots, where a slot has a slot power value. The frame timing of the frames is established from the slot power values. The signal is modified according to a next diversity parameter adjustment in accordance with the frame timing.
