  • Patent number: 9338670
    Abstract: The method comprising measuring by an interfered base station (BS2) the uplink interference and when said uplink interference exceeds a given threshold performing a cancellation process by: discovering and identifying a serving base station (BS1) to which an interfering user device (UE1) is wirelessly connected; requesting to the serving (BS1) the RF fingerprints of the one or more interfering user devices served thereby and using the same frequency resource blocks (RB) of said interfered (BS2); receiving the RF fingerprint of said interfering user device (UE1); consulting said received RF fingerprint in a register; selecting the RF fingerprint more similar to the received one and taking the information of level of interference associated thereto; and using said taken level of interference information for performing said cancelling of said uplink interference.

  • Publication number: 20140241276
    Abstract: In the method of the invention, the overall throughput of a user equipment connected to a serving cell of a cell network is affected by the presence of inter-cell interference of at least a main interfering neighbour cell of said cell network, said user equipment incorporating Successive Interference Cancellation, or SIC, capabilities, and is characterised in that it comprises performing a resources scheduling mechanism and/or power control process in said cell network according to the availability of said SIC capabilities in said user equipment.
