    Abstract: A method for X2 interface communication is disclosed, comprising: at an X2 gateway for communicating with, and coupled to, a first and a second radio access network (RAN), receiving messages from the first RAN according to a first X2 protocol and mapping the received messages to a second X2 protocol for transmission to the second RAN; maintaining state of one of the first RAN or the second RAN at the X2 gateway; executing executable code received at an interpreter at the X2 gateway as part of the received messages; altering the maintained state based on the executed executable code; and receiving and decoding an initial X2 message from the first RAN; identifying specific strings in the initial X2 message; matching the identified specific strings in a database of stored scripts; and performing a transformation on the initial X2 message, the transformation being retrieved from the database for stored scripts, the stored scripts being transformations.

    Abstract: Systems and methods are disclosed for performing training using superimposed pilot subcarriers to determine training data. The training includes starting with a training duration (T) equal to a number of antennas (M) and running a Convolutional Neural Network (CNN) model using training samples to determine if a testing variance meets a predefined threshold. When the testing variance meets a predefined threshold, then reducing T by one half and repeating the running Convolutional Neural Network (CNN) model until the testing variance fails to meet the predefined threshold. When the testing variance fails to meet the predefined threshold, then multiplying T by two and using the new value of T as the new training duration to be used. Generating a run-time model based on the training data, updating the run-time model with new feedback data received from a User Equipment (UE), producing a DL channel estimation from the run-time model; and producing an optimal precoding matrix from the DL channel estimation.

    Abstract: A system is disclosed for cooling telecommunications equipment. The system includes a nozzle disposed proximate a piece of telecommunication equipment to be cooled and a fluid conduit in fluid communication with the nozzle. A fluid supply is coupled to the fluid conduit and provides fluid to the fluid nozzle. A nozzle control system is coupled to the nozzle and configured to actuate the nozzle to cause fluid to emerge from the nozzle, thereby providing a fluid mist to cool the air surrounding at least a part of the telecommunication equipment.

    Abstract: Systems, methods and computer programs are disclosed for providing an indication of a decoding problem in a wireless system. A problem is detected in decoding uplink physical control channels for a Dedicated Physical Control Channel (DPCCH) or an Enhanced Dedicated Physical Control Channel (E-DPCCH). A modified Up Link (UL) Dedicated Channel (DCH) frame having a spare field modified to indicate a Transport Format Combination Indicator (TFCI) decode failure is sent. In response to receiving the modified UL DCH frame, an Up Link (UL) Outer-Loop Power Control (OLPC) is controlled to keep a signal-to-interference ratio (SIR) of the UL DPCCH within a predetermined range.
