Abstract  Abstract

Embodiments for providing virtual carrier sensing for LTE are generally described herein. In some embodiments, a first evolved Node B (eNB) sends a notification of subsequent DL transmission to a first UE in a downlink. In the uplink, the first UE sends a confirmation of the received DL notification. A second eNB overhears the confirmation, decodes it and extracts the information of the DL resources that the first eNB is planning to use. If the second eNB is not already transmitting in the indicated DL resources, the second eNB marks the indicated DL resources as busy and refrains from transmitting in those resources. The second eNB may then reschedule its transmission using alternative resources so that interference from the second eNB1 may be avoided.
