Method and system for data aggregation in an industrial communication protocol

A method and system for interacting with data frames passing through a module connected to an industrial network is disclosed. Each module includes an aggregation unit located on the network interface above the physical layer. To transmit data, the aggregation unit reads a header from a dynamic data packet to determine if the module is a participant module for the packet. If so, the aggregation unit inserts data from the module into the data packet and transmits the packet to another module. To receive data, the aggregation unit reads a header from the data packet to determine whether the data packet includes data for the module. If so, the aggregation unit reads the data and passes the data packet to another module. If the aggregation unit determines that a data packet is not intended for the module, the data packet is passed to another module with no further interaction.

Carrier sense adaptive transmission (CSAT) in unlicensed spectrum
10542435 · 2020-01-21 · ·

Systems and methods for Carrier Sense Adaptive Transmission (CSAT) and related operations in unlicensed spectrum are disclosed to reduce interference between co-existing Radio Access Technologies (RATs). The parameters for a given CSAT communication scheme may be adapted dynamically based on received signals from a transceiver for a native RAT to be protected and an identification of how that RAT is utilizing a shared resource such as an unlicensed band. Other operations such as Discontinuous Reception (DRX) may be aligned with a CSAT Time Division Multiplexed (TDM) communication pattern by way of a DRX broadcast/multicast message. Different TDM communication patterns may be staggered in time across different frequencies. Channel selection for a co-existing RAT may also be configured to afford further protection to native RATs by preferring operation on secondary channels as opposed to primary channels.

Serial communication system

Among serial communication systems between vehicle-mounted communication units, a serial communication system for improving use efficiency of a communication bandwidth in a communication standard LIN has been required. In order to solve this problem, in a serial communication system of LIN, a response of a master node as a write request transmitted from the master node to a slave node and a response of the slave node transmitted from the slave node to the master node are combined into a time base, and a certain period for receiving a response from the slave node is provided after the write request from the master node.

SYSTEMS AND METHODS FOR EFFICIENT TRAFFIC OFFLOAD WITHOUT SERVICE DISRUPTION

Methods, systems, and devices for offloading traffic flows without service disruption are disclosed herein. User equipment (UE) is configured to receive an indication that a current packet data network (PDN) connection can be optimized. The current PDN connection is established over a first PDN gateway (PGW). The UE requests connection over a new PDN connection to a same type of service as the current PDN connection without releasing the connection over the first PGW. The UE routes new traffic flows over a second PGW corresponding to the new PDN connection and routes old traffic flows over the first PGW.

This disclosure relates to a communication device, comprising: a first communication module configured to communicate data with a first communication partner device according to a first wireless technology; a second communication module configured to communicate data with a second communication partner device according to a second wireless technology; and a scheduling module configured to determine a parameter indicative of a receive data capacity of the first communication partner device based on the data communication with the first communication partner device, and to schedule the data communication with the first communication partner device and the data communication with the second communication partner device based on the parameter.

Method, system and apparatus

A method is provided where a set of beams is transmitted from an access point in a first sweeping order in a first cell. The beams transmit a reference signal. A first subset of the beams is configured to be transmitted in a neighbor zone direction of the first cell, within a first common block of time as a second subset of beams being transmitted in a second cell in a neighbor zone direction. Each beam of the first and second subsets of beams are transmitted at different times in the first common block of time.

Traffic and mobility aware virtual access points
10524267 · 2019-12-31 · ·

In one embodiment, a supervisory device in a network classifies mobility and traffic characteristics of a first node in the network. The supervisory device identifies wireless channels supported by access points (APs) in the network. The supervisory device selects one of the wireless channels for use by the first node based on the classified mobility and traffic characteristics of the first node. The supervisory device forms a first virtual access point (VAP) for the first node on the selected wireless channel. A plurality of the access points (APs) in the network that support the selected channel are mapped to the first VAP as part of a VAP mapping. The first node treats the APs in the VAP mapping as a single AP for purposes of communicating with the network.

Identifying bogon address spaces

Systems, methods, and computer-readable media for identifying bogon addresses. A system can obtain an indication of address spaces in a network. The indication can be based on route advertisements transmitted by routers associated with the network. The system can receive a report generated by a capturing agent deployed on a host. The report can identify a flow captured by the capturing agent at the host. The system can identify a network address associated with the flow and, based on the indication of address spaces, the system can determine whether the network address is within the address spaces in the network. When the network address is not within the address spaces in the network, the system can determine that the network address is a bogon address. When the network address is within the address spaces in the network, the system can determine that the network address is not a bogon address.

Communication apparatus and communication method

A communication apparatus includes a receiver and a decoder. The receiver includes a plurality of antenna elements and, in operation, receives from a base station apparatus a modulated signal mapped to one of a plurality of subframes defined in a frame corresponding to a communicable range to which the communication apparatus belongs. The plurality of subframes are defined by time-division, frequency-division, or time-and-frequency division of the frame. A maximum number of modulated signals that can be simultaneously transmitted in a subframe from the base station apparatus varies depending on the communicable range. The decoder, in operation, decodes the received modulated signal.
