    Abstract: A system for an enhanced X2 interface in a mobile operator core network is disclosed, comprising: a Long Term Evolution (LTE) core network packet data network gateway (PGW); an evolved NodeB (eNodeB) connected to the LTE PGW; a Wi-Fi access point (AP) connected to the LTE PGW via a wireless local area network (WLAN) gateway; and a coordinating node positioned as a gateway between the LTE PGW and the eNodeB, and positioned as a gateway between the LTE PGW and the Wi-Fi AP, the coordinating node further comprising: a network address translation (NAT) module; and a protocol module for communicating to the eNodeB and the Wi-Fi AP to request inter-radio technology (inter-RAT) handovers of a user equipment (UE) from the eNodeB to the Wi-Fi AP and to forward packets intended for the UE from the eNodeB to the Wi-Fi AP.

    Abstract: A method for providing increased backhaul capacity in an ad-hoc mesh network is disclosed. The method involves attaching a mobile base station in an ad-hoc mesh network to a macro cell; measuring at least one of a backhaul signal quality with the macro cell and a throughput to the macro cell; reporting information, including a signal quality parameter, a physical position of the mobile base station, a cell identifier of the macro cell, and the measured throughput, to a coordinating node; determining if the connection between the mobile base station and the macro cell is currently in use by the ad-hoc mesh network, and whether the link exceeds a minimum quality threshold; and sending, to the mobile base station, an instruction to advertise a connection from the mobile base station to the macro cell to other nodes in the ad-hoc mesh network.

    Abstract: A method for providing a Real-Time PHY model at a RAN edge involves running an Artificial Intelligence (AI) model on a general-purpose processor in the cloud using telecommunications data as inputs to generate outputs. These inputs and outputs are stored in a lookup format to facilitate lookup without concurrently storing the AI model. The stored inputs and outputs are then deployed to a Virtual Base Band Unit (VBBU), where in-memory lookup of parameters is used for real-time telecommunications data. The method may also include storing the inputs and outputs with compression and periodically refreshing them by re-running the AI model and deploying a new lookup format to the VBBU. The telecommunications data can be radio frequency physical layer data or 4G/5G media access control (MAC) layer data.

    Abstract: A method is disclosed for performing timing advance command (TAC) updates, comprising: configuring an appropriate block error rate (BLER); forwarding a timing advance command (TAC) for a radio network temporary identifier (RNTI) x to a user equipment (UE), the TAC not equal to 31; tracking a time of receipt of a first downlink shared channel (DLSCH) protocol data unit (PDU) with redundancy version (RV) 0 at the user equipment (UE); adding k slots; and continuing tracking timing advance (TA) samples of the radio network temporary identifier (RNTI) x, where k may be based on the subcarrier spacing.

    Abstract: Systems, methods and computer software are disclosed for providing high resolution timing advance estimation based on Physical Random Access Channel (PRACH). An example method includes receiving a preamble signal r(n) having a predetermined sampling frequency and a predetermined length; correlating a down sampled version of the received preamble with a reference preamble sequence c(n) using an FFT method to provide correlation output Ryc; using a peak value P of the correlation output Ryc to detect a preamble ID and a timing advance at a resolution of 24Ts; zero padding sequences Y(k) and C(k) so that they have a predetermined length resulting in sequences Y_hat(k) and C_hat(k), which are 1024-point FFT of y(n) and c(n); performing a maximum likelihood estimation (MLE) to estimate a timing offset; and detecting a peak value out of the R_hat(m) and using a corresponding index Q to provide a timing advance with an accuracy of 2Ts.
