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 may be disclosed for energy savings in cellular networks, comprising: collecting performance data from the cellular network; sharing the performance data with a batch process to train a prediction model; loading the prediction model into a closed-loop process; using the performance data in combination with the trained prediction model to predict cellular access network load for a particular cell; using the predicted cellular access network load to determine a recommended action; and executing the recommended action. The method may be implemented using a public cloud. The trained prediction model may be used to classify different cells and determine different recommended actions for the different cells.

Abstract: In one embodiment, a method includes transmitting a plurality of beamformed reference signals using a corresponding plurality of beamforming precoders; receiving from each of the plurality of UEs a signal quality metric for at least a subset of the plurality of beamformed reference signals; determining a beam-specific cross-correlation for pairs of the plurality of UEs using the signal quality metrics; determining one or more scheduling groups of UEs from the plurality of UEs based on the beam-specific cross-correlation for pairs of the plurality of UEs; and allocating a set of time-frequency resource elements to two or more UEs selected from one of the determined scheduling groups.

Abstract: A multi-radio access technology (multi-RAT) remote radio head (RRH) is disclosed, comprising: a first functional radio unit (RU) providing RF and Low PHY functions for a first RAT; a second functional radio unit (RU) providing RF functions for a second RAT; and a shared radio fronthaul interface in communication with a virtual baseband unit (VBBU) for the first RAT and the second RAT, The first functional RU and the second functional RU use the shared radio fronthaul interface to send partially processed radio data to the VBBU.
