Abstract:
In accordance with one or more embodiments, a communication device includes an antenna array configured to receive first millimeter wave (MMW) signals from a remote device in a millimeter wave (MMW) frequency band and to transmit second millimeter wave (MMW) signals to the remote device in the MMW frequency band. A base transceiver station is configured to generate a consolidated steering matrix in accordance in a radio frequency (RF) band based on a consolidated feedback matrix in accordance with the RF band, wherein the MMW frequency band is above the RF band. A remote radio head is configured to: process the first MMW wave signals received from the remote device to recover an original feedback matrix in accordance with the MMW frequency band; convert the original feedback matrix in accordance with the MMW frequency band to the consolidated feedback matrix in accordance with the RF band; convert the consolidated steering matrix to a converted steering matrix that facilitates the transmission of the second MMW signals to the remote device in the MMW frequency band, and is further configured to generate the second MMW signals in accordance with the converted steering matrix.
