    Abstract: A system and method for arbitrating channel access in a wireless device including co-located network transceivers are disclosed herein. A wireless device includes a first wireless transceiver and a second wireless transceiver. The first transceiver is configured for operation with a first wireless network. The second transceiver is configured for operation with a second wireless network. The wireless device further includes logic that determines which of the first and second transceivers is enabled to transmit at a given time. The logic causes the first transceiver to transmit a notification signal indicating a time period during which the second transceiver of the wireless device will perform a first wireless transaction, and during which, based on receiving the notification signal, a different wireless device performs a second wireless transaction via the second wireless network without transmitting a notification signal.

    Abstract: A network includes an intermediate node to communicate with a child node via a wireless network protocol. An intermediate node synchronizer in the intermediate node facilitates time synchronization with its parent node and with the child node. A child node synchronizer in the child node to facilitates time synchronization with the intermediate node. The intermediate node synchronizer exchanges synchronization data with the child node synchronizer to enable the child node to be time synchronized to the intermediate node before the intermediate node is synchronized to its parent node if the intermediate node has not synchronized to its parent node within a predetermined guard time period established for the child node.

    Abstract: In examples, a vehicular battery management system (BMS) comprises a set of battery cells and a secondary network node coupled to the set of battery cells. The secondary network node is configured to measure a parameter in the set of battery cells and generate a packet containing the parameter. The packet indicates a number of super frame slots that have elapsed from a start time of a super frame to the generation of the packet. The secondary network node is configured to wirelessly transmit the packet within the super frame to a primary network node. The primary network node is configured to wirelessly receive the packet and to determine a time at which the secondary network node generated the packet based on the indication, a time duration of each slot in the super frame, and the start time of the super frame.

    Abstract: A network includes a parent node and at least one child node configured to communicate with the parent node via a wireless network protocol. The parent node includes a broadcast coordinator to transmit a broadcast message from the parent node to the child node at predetermined time intervals according to the wireless network protocol. A scheduler generates a scheduling packet that is communicated in the broadcast message. The scheduling packet includes a data field to instruct each child node to activate and receive data communicated from the parent node in a prescribed time slot following the broadcast message that is defined by the scheduling packet.

    Abstract: Methods, apparatus, systems and articles of manufacture are described for a wireless battery system. An example apparatus includes at least one memory, instructions, and processor circuitry to at least one of instantiate or execute the instructions to identify a first battery node to transmit an uplink command during a first superframe interval, transmit a downlink command to the first battery node and a second battery node, the first battery node to switch in the first superframe interval from a receive state to a transmit state in response to the downlink command, the first battery node to transmit the uplink command in the transmit state, and receive the uplink command from the first battery node in the first superframe interval.
