Abstract  Abstract

The invention generally claims for providing embodiments of the LTE and the virtual carrier sense. In some embodiments the first evolution node B (eNB) sends notification of subsequent DL transmission to the first UE in downlink. in the uplink the first UE sends notification of received DL acknowledgement. the second eNB overhear the confirmation decoding the acknowledgement information of DL resource and extracting the first eNB plan. If the second eNB and is not indicated by the DL resource to send the second eNB indicated by DL resource is marked as busy and inhibition of such resources for transmission. the second eNB may then use alternative resource scheduled for transmission so that interference from the second eNB1 can be avoided.

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.
