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.
Claims11
A physical layer collision avoidance device, belonging to a physical layer collision avoidance network, wherein the physical layer collision avoidance device comprises:
- a communication circuit;
- and
- a controller, coupled to the communication circuit and configured to:
- in response to determining that the physical layer collision avoidance device enters an emergency transmission mode, find a first physical layer collision avoidance device that is performing a corresponding first packet transmission;
