Abstract: A bandwidth part (BWP) and power scheduling method and apparatus for indoor terahertz are provided. The BWP and power scheduling method uses an intelligent reflecting surface (IRS) and a non-orthogonal multiple access (NOMA) to compensate for a shortcoming, wherein terahertz waves are not suitable for an indoor transmission, convert an indoor environment of an IRS-assisted terahertz propagation into a channel model, and convert an optimal wireless resource scheduling in an indoor IRS-assisted terahertz system into a functional optimization design with random constraints. Policies and corresponding actions are trained by using a proximal policy optimization (PPO) to schedule a power and a BWP. An actor part generates continuous a power scheduling, and a critic part generates a discrete BWP scheduling.

Abstract: In order to establish a mesh network, an electronic device may iteratively identify one or more mesh-network nodes and may determine associated duty-cycle ratios based on communication with the one or more mesh-network nodes. In particular, the electronic device may select candidate mesh-network nodes based on estimated throughput metrics of their communication with a root device in the mesh network. Then, for each of the candidate mesh-network nodes, the electronic device may associate with a given candidate mesh-network node, and may measure the throughput of the given candidate mesh-network node during a time interval by communicating packets. Based on comparisons of the measured throughputs, the electronic device may identify the one or more mesh-network nodes in the candidate mesh-network nodes and may determine the associated duty-cycle ratios. Subsequently, the electronic device communicates information with the root device via the one or more mesh-network nodes based on the duty-cycle ratios.

Abstract: In a managed wireless environment where a controller is gathering data in order to optimize the wireless network, certain data parameters are gathered in order to optimize the network. The gathered parameters are then utilized to determine best case links for various attached wireless station devices in order to: 1) optimize the network and 2) optimize the per station (STA) links. The control points utilized to determine the network optimization will vary based on the desired outcomes for the system. As such, configurable ‘profiles’ will be utilized in order to prioritize outcomes for the system. These profiles may be utilized by the network steering controller in order to steer wireless station devices to optimize the network in the desired fashion.

Abstract: The information transmission control device according to the present disclosure is for controlling a position to start transmitting probe data to a server; the information transmission control device uses a vehicle's current lane segment information and history information about the vehicle's having transmitted probe data, to set a transmission interval distance and an offset for changing a position to start transmitting probe data. By using the transmission interval distances and the offsets, transmission start positions to transmit probe data are shifted on a running unit basis or on a vehicle basis. Therefore, while the vehicle stops, multiple data transmission at the same position does not occur. This can reduce the communication cost, and makes it possible to obtain information evenly on the travel route.

Abstract: The present application generally relates to a system and method for interfacing a source-selected path routing network with existing legacy IP networks. This interfacing may be achieved by installing specific router devices at the borders of the source-selected path routing network. Said router devices are able to exchange routing information in the form of IP prefix announcements and withdrawals between legacy IP networks and the source-selected path routing network according to an appropriate exterior gateway protocol. Hereby, the source-selected path routing network that in reality comprises a plurality of autonomous systems is conceptually regarded as a single autonomous system. Hence, a legacy IP network that is a direct neighbor of a source-selected path routing network may ensure that traffic destined to it traverses the source-selected path routing network by announcing its routing information only to the source-selected path routing network via an appropriate exterior gateway protocol.

Abstract: A first user equipment (UE) device receives a configuration for a first timer from a base station that is serving the UE device. The first UE device also receives a recommended bitrate from the base station. The recommended bitrate is to be used for a Voice over Long-Term Evolution (VoLTE) call or a Video over Long-Term Evolution (ViLTE) call between the first UE device and a second UE device. The first UE device activates the first timer in accordance with the configuration. The first UE device is prohibited from transmitting a bitrate query to the base station while the first timer is running. Upon receiving a recommended bitrate that is below a Guaranteed Bit Rate for the call between the first UE device and the second UE device, the first UE device stops the first timer and transmits a bitrate query to the base station.
