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.

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: A scheduler for transmission of Packetized data over a transmission link between a base station device and various terminal devices, each packet being associated with one terminal device, and the packets being of variable length. The scheduler calculates for each terminal device a proportional fair allocation metric, assigns a next available channel transmission resource to a device having a best metric, but only actually sends a next packet to a respective terminal device provided that respectively allocated and as yet unused channel transmission resources are sufficient to accommodate the next packet. Thus the packets are sent unfragmented and based on a proportional fair resource allocation.

Abstract: A method of operating a communication system having a plurality of data channels for downlink transmission from a base station to a plurality of subscriber stations. The method comprises receiving, at a base station, an inflow having a plurality of packets of a plurality of connections, each the connection being with one of a plurality of subscriber stations, regulating the inflow according to a throughput rate, setting a deadline to each the packet in the regulated inflow as a function of its reception time, and scheduling a transmission of the plurality of packets to the plurality of subscriber stations according to their deadlines so as to guarantee substantially the throughput rate for each one of the plurality of connections.
