    摘要: Varying embodiments of the present invention describes a method and apparatus for beamforming in a wireless communication system. A first embodiment is a method for beamforming in a wireless communication system, the system comprising a transmitter and a receiver. The method comprises initiating beamforming on a communication channel between the transmitter and the receiver wherein the communication channel comprises at least two transmit chains, controlling the beamforming by mapping the data stream(s) to the at least two transmit chains and controlling the scaling of the at least two transmit chains within a transmit power constraint.

    摘要: A method, system, and computer program product for beamforming in a wireless communication system is disclosed. The method, system, and computer program product comprise a plurality of transmit antennas for a transmitter and at least one receive antenna for a receiver. The method, system, and computer program product comprise: initiating beamforming on a communication channel between the plurality of transmit antennas and the at least one receive antenna. The communication channel includes two data streams. A received signal to noise ratio (SNR) on one of the two data streams is weaker than a received SNR of the other data stream. The method, system, and computer program product include reallocating the transmit power between the stronger stream and the weaker stream to provide improved channel performance.
