Adaptive transmit beamforming for frequency division duplexing systems |
摘要 |
Embodiments of a method and apparatus for performing an adaptive transmission scheme in a frequency division duplexing communication system based on channel state information estimated using an open-loop mode are described herein. In one example, the method includes estimating an impulse response of a channel using a signal received over a first frequency band of the channel from a device, transforming the impulse response into a frequency response of the channel, and subsequently performing the adaptive transmission scheme using the frequency response to transmit a signal to the device over a second frequency band of the channel that is different from the first frequency band. |
