Abstract
Embodiments of an eNB and method for supporting communication with UEs on an LTE network in an unlicensed frequency band are generally described herein. The eNB may be configured to transmit a first LTE signal that includes a first reference signal during an active transmission period of a Wi-Fi network in the unlicensed frequency band, and to restrict frequency spectra used for the transmission of the first LTE signal from frequency spectra used by the Wi-Fi network during the active transmission period. The first reference signal may enable maintenance of synchronization between the eNB and the UEs at least during the active transmission period. The eNB may be further configured to transmit a second LTE signal during a silence period of the Wi-Fi network in frequency spectra used by the Wi-Fi network during the active transmission period.
