Abstract: In some examples, a battery management system (BMS) includes a set of battery cells and a secondary network node coupled to the set of battery cells. The secondary network node is configured to, responsive to determination by the secondary network node of an exception event, wirelessly transmit a series of periodically repeating reverse wake up data frames to a primary network node. The secondary network node is also configured to, responsive to receipt of a synchronization frame from the primary network node after transmitting the series of reverse wake up data frames, transmit an uplink data frame to the primary network node.

Abstract: In an example, a method includes receiving, in a super frame, a first downlink on a first channel from a wireless master node at a wireless head node in a WBMS, where the wireless head node is a head node for a sub-cluster of one or more wireless devices. The method includes transmitting, in the super frame, a second downlink on a second channel from the wireless head node to each of the one or more wireless devices. The method includes receiving, in the super frame, an uplink from each of the one or more wireless devices at the wireless head node on the second channel. The method includes transmitting, in the super frame, an aggregated uplink from the wireless head node to the wireless master node on the first channel, where the aggregated uplink includes data from each of the one or more wireless devices.

Abstract: In an example, a method includes transmitting a plurality of wake-up frames on a transmission channel from a first node having a first priority. The method also includes pausing the wake-up frames from the first node and listening to the transmission channel after a predetermined number of wake-up frames are transmitted from the first node. The method also includes receiving, at the first node, a wake-up frame from a second node on the transmission channel, wherein the second node has a second priority.

Abstract: In an example, a method includes receiving, in a first super frame, a first downlink on a first channel from a wireless master node at a wireless device in a WBMS, where the first downlink indicates a second channel assigned to the wireless device. The method includes transmitting, in the first super frame, a synchronization frame from the wireless device to an unsynchronized wireless device on the second channel, where the synchronization frame indicates a third channel. The method also includes receiving, in the first super frame, the synchronization frame at the unsynchronized wireless device on the second channel. The method includes transmitting, on the third channel in a second super frame after the first super frame, an uplink from the unsynchronized wireless device to the wireless master node.
