    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.

    Abstract: Systems, methods and computer software are disclosed for a Self Organizing Network (SON) Radio Access Technology (RAT) selection for User Equipment (UE) in a virtualized Radio Access Network (RAN) environment. In one embodiment, a method is disclosed, comprising: establishing, by the UE, a Signaling Radio Bearer (SRB) and at least one Data Radio Bearer (DRB) with a Virtual node (Vnode); determining, by the SON, whether the Vnode has reached a data saturation limit; when the Vnode has reached the data saturation limit, then determining whether there is another RAT Vnode which can provide better data throughput; and when there is another RAT Vnode which can provide better data throughput, then initiating a handover procedure for the UE and specifying a target cell located in a same geographic area.

    Abstract: Generally, a combination of the following features are present to provide a centralization solution, in some embodiments: Latency compensation and auto-calibration of the delay between the PHY and the radio; Leveraging loopback in the radio (ORAN standard defined); Measurement based on air timing and/or RRH early/late feedbacks; and ability to understand routing changes and recalibrate latency compensation. In one embodiment, a method is provided for providing workload redundancy in a virtualized radio access network (RAN), comprising: distributing a baseband workload from a plurality of cells onto a first virtualized baseband unit (vBBU) at a centralized site; provisioning a second vBBU as a redundant vBBU for the plurality of cells; synchronizing state from the first vBBU to the second vBBU according to a first periodicity; performing failover from the first vBBU to the second vBBU at a first time; and adjusting an operating latency during the performed failover such that the plurality of cells continues operation without an interruption of service.

    Abstract: Systems, methods and computer software are disclosed for resolving multiple contexts for a User Equipment (UE) in a wireless network. In one embodiment a method includes maintaining, for a coordinating node hosting a first Radio Access Technology (RAT) controller and a second RAT controller simultaneously, a centrally maintained database; determining, based on the contents of the centrally maintained database, when the UE is registering with the second RAT controller while currently registered with the first RAT controller; and sending, by the second RAT controller, a deregistration command to the first RAT controller the UE was registered with, wherein context is freed and wherein resources held at both the coordinating node and at a base station are freed.
