  • Publication number: 20160294698
    Abstract: The method comprises identifying and classifying, by a classification unit (102), received data packets flows between fixed bit rate data packets flows (FB) and variable bit rate data packets flows (VB); sending the identified and classified fixed bit rate data packets flows (FB) to a pacer unit (103) spacing the transmission of the fixed bit rate data packets flows (FB) towards an egress port of the transport node (100); and sending the configuration parameters relating to the variable bit rate data packets flows (VB) to a virtual queue unit (104), said virtual queue unit (104) including a processor running an algorithm to activate one or more congestion correction procedures, wherein in case the result obtained by said algorithm being over, or equal, at least one threshold activating a corresponding congestion correction procedure.

  • 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.

  • Patent number: 9119216
    Abstract: This invention proposes a method for assigning resources in the downlink based on the CQI parameter reported by the UE compatible with the LTE standard. The method looks for saving signalling resources when conditions are such that no major advantage can be obtained from frequency selective scheduling. The method is divided into two processes, a non real time process used to determine whether the conditions for its application are present; and the new assignment procedure. For the latter, the method defines different assignment procedures based on whether the CQI value reported by the UE is higher or not of a given threshold whose calculation is also defined. A new parameter, the MAB, is defined for the assignment in case of CQI higher than the threshold, while frequency distributed scheduling is used if it is lower. The proposed method is believed to improve the LTE spectral efficiency with reduced complexity.

  • Patent number: 9112548
    Abstract: A method to optimize the power assignment of user streams transmitted from base stations in coordinated base station transmission systems. In the method of the invention said CBST systems employ block diagonalization techniques and are deployed in MIMO-OFDM scenarios, and it further comprises using a new waterfilling technique which provides a performance very close to the theoretical ideal but with a reduced computational complexity.

  • 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.
