A file copy controller in a wireless access device reads file system management information of both of a local memory and a remote memory, generates a FS transfer list in which logical address positions of copy sources and logical address positions of copy destinations are stored, and inputs the FS transfer list to a non-volatile memory controller connected to the local memory. The non-volatile memory controller performs copy operation between the local memory and the remote memory based on the information stored in the FS transfer list without using a CPU in an access device or an internal bus connected to the CPU.

The present invention relates to a distributed radio base station, and provides a distributed radio base station, including: one or more base units (BUs) configured to process digital signals; and one or more radio units (RUs) installed in one or more target service areas, and configured to wirelessly communicate with pieces of user equipment; wherein each of the BUs is coupled to a cell group, composed of a set of RU groups each formed by grouping one or more of the RUs, over a transport network.

A wireless communication system includes a first wireless communication node for transmitting a data signal that is sent to a second wireless communication node by skywave propagation over at least two different data transmission paths. The first data transmission path includes at least one reflection point where the data signal is reflected by the atmosphere and the second data transmission path includes more reflection points than the first data transmission path. The data signal that travelled along the first data transmission path is decoded before the data signal that travelled along the second data transmission path.

A system is provided where one of a first device or a second device is supplied with power by the other one of the first device or the second device. Supplying may be done via a universal serial bus cable like a universal serial bus Type-C cable.

A filter monitor system (“FMS”) module is installed on the engine/vehicle and is connected to the filter systems, sensors and devices to monitor various performance parameters. The module also connects to the engine control module (“ECM”) and draws parameters from the ECM. The FMS module is capable of interfacing with various output devices such as a smartphone application, a display monitor, an OEM telematics system or a service technician's tool on a computer. The FMS module consists of hardware and software algorithms which constantly monitor filter systems and provide information to the end-user. FMS module provides necessary inputs and outputs for electronic sensors and devices.

A method performed by a distributed base station system of a wireless communication network. The distributed base station system comprises a base band unit (BBU) and a remote radio unit (RRU) connected to each other over a fronthaul link. The method comprises receiving uplink signals at N antennas of the RRU from a number of user equipment (UEs) connected to the RRU. The BBU determines first beamforming weights based on a first reference signal that is has received from the UEs and sends the first beamforming weights to the RRU. The RRU then determines intermediate signals from the first beamforming weights and the uplink signals and sends the intermediate signals to the BBU. The BBU then determines second beamforming weights from a second reference signal it has received from the RRU. Then, the BBU determines an output signal based on the intermediate signal and the second beamforming weights.
