And the first transmission data unit is transmitted to the second communication node when the size of the data resource is larger than the size of the first transmission data unit. The method of claim 9,
Wherein the data resource is determined in consideration of at least one of a priority of the first transmission data unit and a second transmission data unit and a delay weight reflecting delay information of the first transmission data unit. 14. The method of claim 13,
Wherein resources are additionally allocated to the first communication node and the second communication node when propagation delay of the first control information occurs. The method of claim 9,
Wherein the at least one instruction comprises:
The size of the first transmission data unit transmitted to the first communication node to the third communication node when the size of the first transmission data unit is larger than the total resource size between the first communication node and the second communication node, Wherein the first communication node is adapted to send a message requesting to reduce the first communication node. The method of claim 9,
Wherein the at least one instruction comprises:
If the size of the first transmission data unit is greater than the total resource size between the first communication node and the second communication node, replacing the first transmission data unit transmitting to the first communication node to a third communication node And to send a message requesting distributed processing through the communication node. A method for resource allocation by a second communication node,
Transmitting to the first communication node second control information including a size of a second transmission data unit to be transmitted by the second communication node and a priority of the second transmission data unit;
Receiving from the first communication node first control information including a size of a first transmission data unit to be transmitted by the first communication node and a priority of the first transmission data unit;
Determining a data resource used for transmission of the second transmission data unit based on a ratio of the size of the first transmission data unit and the size of the second transmission data unit; And
And transmitting the second transmission data unit via the data resource to the first communication node. 18. The method of claim 17,
When the size of the data resource is smaller than the size of the second transmission data unit, the first transmission data unit corresponding to the size of the data resource is transmitted to the first communication node,
Wherein if the size of the data resource is greater than the size of the first transmission data unit, the first transmission data unit is transmitted to the second communication node. 18. The method of claim 17,
Wherein the data resource is determined in consideration of the priority of the first transmission data unit and the second transmission data unit. 18. The method of claim 17,
The resource allocation method includes:
And if the size of the second transmission data unit is greater than the total resource size between the first communication node and the second communication node, the size of the second transmission data unit to be transmitted to the second communication node to the fourth communication node Sending a message requesting a fourth communication node to distribute the first transmission data unit transmitting to the first communication node through an alternate communication node, Resource allocation method.
