Abstract: Embodiments of the disclosure provide a physical layer collision avoidance (PLCA) device and a method for performing emergency transmission thereof. The method includes: in response to determining that the PLCA device enters an emergency transmission mode, finding a first PLCA device that is performing a corresponding first packet transmission; in response to determining that a first transmission priority of the first PLCA device is lower than a transmission priority of the PLCA device, suspending the first packet transmission of the first PLCA device; and in response to determining that it is the PLCA device's turn to perform a corresponding packet transmission, sending an emergency packet corresponding to the emergency transmission mode.

Abstract: A physical layer collision avoidance (PLCA) device and a method for automatically determining a node identity for the PLCA device are provided. The method includes: generating a random number as identification information of the PLCA device, wherein the PLCA device maintains an identification information table and a device count; receiving a first synchronization packet, wherein the first synchronization packet includes first identification information of a first PLCA device; determining a first comparison result between the identification information of the PLCA device and the first identification information of the first PLCA device; updating the identification information table and the device count based on the first comparison result; sending a synchronization packet corresponding to the PLCA device based on the first comparison result; and determining the node identity of the PLCA device in a PLCA network based on the identification information table.
