Network system comprising multiple access network gateways interconnected via networking equipment, each of the access network gateways being adapted for connecting user equipment devices to the network system, wherein the network system comprises a database wherein private networks are defined as groups of predetermined user equipment devices, and wherein the access network gateway are configured to interconnect user equipment devices belonging to a single private network via SDN service chains to emulate the single private network inside the network system.

In some examples, a software-defined network (SDN) controller determines a link aggregation (LAG) configuration for a node in the SDN that is controlled by the SDN controller. The LAG configuration is based on hardware capability information and dynamic network traffic information of the SDN. The SDN controller can further instruct the node to forward traffic in accordance with the LAG configuration.

A method for receiving an Orthogonal Frequency Division Multiplexing (OFDM) signal transmitted by a user device in a wireless network comprises determining which subcarrier frequencies are allocated to the user device; converting the OFDM signal to a frequency-domain values corresponding to the subcarrier frequencies; and decoding the frequency-domain values to recover data symbols encoded by the user device on the subcarrier frequencies. The decoding employs codes that are inverse to, complex-conjugate of, or complementary to a set of complex-valued codes employed by the user device to shape the OFDM signal into a superposition of cyclic-shifted pulse waveforms, wherein each of the pulse waveforms has one of the data symbols modulated thereon.

A telecommunications network comprises at least one core network interface for providing interconnection to a core network. At least one base station interface provides communications to at least one user device. At least one server defines a configurable network interconnecting the at least one core network interface and the base station.

The at least one server defines logically independent network slicing for the configurable network that selects a first network slice responsive to use of the configurable network by a first application and selects a second network slice responsive to use of the configurable network by a second application. The at least one server implements the VRAN in a first configuration responsive to use of the first application by the configurable network and a second configuration responsive to use of the second application by the configurable network. At least one transceiver associated with the at least one base station interface for provides massive MIMO communications between the at least one server and the at least one user device.

A base station type replacement method, a software defined radio (SDR) network management system, a base station type replacement apparatus and a non-transitory computer-readable storage medium are disclosed. The method may include: creating a blank target base station rack diagram in a view area in a source base station rack diagram according to a new base station creation operation of a user through an SDR network management system (201); and moving a graphical managed object (MO) in the source base station rack diagram to the target base station rack diagram according to a graphical move operation of the user, storing service location keyword information of the MO in the source base station rack diagram and the target base station rack diagram, and configuring data of a target base station based on the target base station rack diagram during the graphical move operation to complete base station type replacement (202).

Disclosed in some examples are systems, methods, devices, and machine-readable mediums for improved communications between a software-defined radio front-end device and a network-based computing device. Rather than packetize samples together, same bit positions from multiple ADC samples may be packetized together. If a Quality of Service (QoS) metric of the network connection between the RF front-end device and the network-based processing computing drops below a threshold, the RF front-end device may prioritize sending packets with the more significant bits over packets with less significant bits. In other examples, the RF front-end device may prioritize samples corresponding to certain data types over other data types.

The electronic device includes a universal serial bus (USB) connector connectable to an external electronic device including a radio reception circuit configured to receive a radio signal and to convert the received radio signal into a digital signal, and a signal processing circuit configured to generate a sound corresponding to the digital signal based on a control signal transmitted by the electronic device, and a processor. The processor may be configured to: receive information of the external electronic device in response to detecting that the external electronic device is connected to the USB connector, determine whether the external electronic device is capable of processing the radio signal based on the information of the external electronic device, activate a radio framework configured to control a radio reception function of the external electronic device in response to identifying that the external electronic device is capable of processing the radio signal, and control the external electronic device based on the operation of the USB framework, which receives the control signal generated by the radio framework. In addition, various embodiments are possible.

The method for executing a radio application is a method for executing a radio application independent of a modem in a terminal device, comprising the steps of: communicating with each other using a reconfigurable radio frequency interface (RRFI) by a unified radio application (URA), which operates on a radio computer of the terminal device, and a radio frequency (RF) transceiver, which operates in a radio platform on the radio computer; and supporting, by the RRFI, at least one service among a spectrum control service, a power control service, an antenna management service, a transmission/reception chain control service, and a radio virtual machine protection service.

This disclosure presents distributed and decentralized synchronization for wireless transceivers. The disclosed system, device, and method achieve sub-nanosecond synchronization using low-cost commercial off the shelf software defined radios. By providing a decentralized mechanism that does not rely on a hierarchical master-slave structure, networks constructed as disclosed are robust to sensor drop-out in contested or harsh environments. Such networks may be used to create phased array radars and communication systems without requiring wired connections to distribute a common clock or local oscillator reference.

A radio timing controller equipped with one or more sequence controllers is disclosed. Sequence controllers enable high degree of programmability of the radio timing controller, e.g., in terms of the number of general purpose input/outputs (GPIOs), mapping of GPIOs to specific radio controls, setting of the radio control output states, timing to sequence events at radio symbol boundaries, etc.
