METHOD AND APPARATUS FOR ALLOCATING PRIORITY TRANSMISSION OPPORTUNITIES IN VEHICLE NETWORK
First Claim
1. An operation method of a first end node in a vehicle network supporting a physical layer collision avoidance (PLCA) function, comprising:
- performing, by a controller, a monitoring operation in a first time interval configured for communication of the first end node;
detecting, by the controller, a transmission request signal transmitted from a second end node by the monitoring operation; and
in response to detecting the transmission request signal, stopping, by the controller, a transmission operation of the first end node in the first time interval,wherein the first time interval is used for communication of a second end node instead of the first end node.

Abstract
An operation method of a first end node in a vehicle network supporting a PLCA function is provided. The method includes performing a monitoring operation in a first time interval configured for communication of the first end node and detecting a transmission request signal transmitted from a second end node by the monitoring operation. In response to detecting the transmission request signal, a transmission operation of the first end node in the first time interval is stopped. The first time interval is used for communication of a second end node instead of the first end node.

11. An operation method of a first end node in a vehicle network supporting a physical layer collision avoidance (PLCA) function, comprising:
-
generating, by a controller, a transmission request signal indicating that data to be transmitted exists; transmitting, by the controller, the transmission request signal in a first time interval configured for communication of a second end node; and performing, by the controller, a transmission operation of the first end node in the first time interval, wherein the first time interval is used for communication of the first end node instead of the second end node. - View Dependent Claims (12, 13, 14, 15)

16. An operation method of a first end node in a vehicle network supporting a physical layer collision avoidance (PLCA) function, comprising:
-
detecting, by a controller, a transmission request signal transmitted from a third end node in a first time interval configured for communication of a second end node; in response to detecting the transmission request signal, changing, by the controller, a time interval configured for communication of the first end node from a second time interval to a third time interval after the second time interval; and performing, by the controller, a transmission operation of the first end node in the third time interval, wherein a transmission operation of the third end node is performed in the first time interval, and the transmission operation of the second end node is performed in the second time interval after the first time interval. - View Dependent Claims (17, 18, 19, 20)
