METHOD AND APPARATUS FOR ALLOCATING TRANSMISSION OPPORTUNITIES IN VEHICLE NETWORK
First Claim
1. An operation method of a first end node constituting an Ethernet-based vehicle network, the operation method comprising:
- receiving a first beacon from a second end node, the beacon including first configuration information of a first main-cycle including a plurality of sub-cycles each of which includes N time slots;
transmitting a signal in a time slot corresponding to an identifier of the first end node among the N time slots within a sub-cycle # k of the plurality of sub-cycles; and
transmitting a signal in a time slot corresponding to the identifier of the first end node among the N time slots in a sub-cycle # (k+1) consecutive with the sub-cycle # k of the plurality of sub-cycles,wherein a number of end nodes having transmission opportunity in the sub-cycle # k is greater than a number of end nodes having transmission opportunity in the sub-cycle # (k+1), N is a natural number equal to or greater than 2, and K is a natural number equal to or greater than 1.

13. A first end node constituting an Ethernet-based vehicle network, the first end node comprising:
-
a physical (PHY) layer unit including a PHY layer processor; a controller unit including a controller processor; and a memory storing at least one instruction executable by the PHY layer unit and the controller unit, wherein when executed by the PHY layer unit and the controller unit, the at least one instruction is configured the PHY layer unit and the controller unit to; receive a first beacon from a second end node, the beacon including first configuration information of a first main-cycle including a plurality of sub-cycles each of which includes N time slots; transmit a signal in a time slot corresponding to an identifier of the first end node among the N time slots within a sub-cycle # k of the plurality of sub-cycles; and transmit a signal in a time slot corresponding to the identifier of the first end node among the N time slots in a sub-cycle # (k+1) consecutive with the sub-cycle # k of the plurality of sub-cycles, wherein a number of end nodes having transmission opportunity in the sub-cycle # k is greater than a number of end nodes having transmission opportunity in the sub-cycle # (k+1), N is a natural number equal to or greater than 2, and K is a natural number equal to or greater than 1. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
