Resource use method of node in wireless communication system and device using same

1. A resource use method of a node in a wireless communication system, the method comprising:

receiving first allocation information related to communication with a parent node and second allocation information related to communication with a child node; and

communicating with the parent node or the child node using a particular resource based on the first allocation information and the second allocation information,

wherein based on the second allocation information informing the particular resource as a soft resource among a hard resource, the soft resource and an unavailable resource and based on no explicit indication that the particular resource is available for the communication with the child node, the particular resource is used for the communication with the parent node.

2. The method of claim 1 , wherein the first allocation information informs that a resource type of the particular resource is one of downlink, uplink, and flexible.

3. The method of claim 1 , wherein the second allocation information informs that a resource type of the particular resource is one of hard downlink, soft downlink, hard uplink, soft uplink, hard flexible, soft flexible, and not-available.

4. The method of claim 3 , wherein the hard downlink informs that the particular resource is a resource that is always available for the node to transmit a signal to the child node, and the soft downlink informs that the particular resource is a resource through which transmission of a signal by the node to the child node is controlled by the parent node.

5. The method of claim 3 , wherein the hard uplink informs that the particular resource is a resource that is always available for the node to receive a signal from the child node, and the soft uplink informs that the particular resource is a resource through which reception of a signal by the node from the child node is controlled by the parent node.

6. The method of claim 3 , wherein the hard flexible informs that the particular resource is a resource that is always flexible in a relationship between the node and the child node, and the soft flexible informs that the particular resource is a resource of which the flexibility in the relationship between the node and the child node is controlled by the parent node.

7. The method of claim 3 , wherein the not-available informs that the particular resource is a resource that is unavailable in a relationship between the node and the child node.

8. The method of claim 1 , wherein based on the second allocation information informing the resource as a soft downlink, soft uplink, or soft flexible resource and the resource being allocated to the node by the first allocation information, the resource is considered to be used for the communication with the parent node.

9. The method of claim 1 , wherein based on the second allocation information informing the resource as a soft downlink, soft uplink, or soft flexible resource and the resource not being allocated to the node by the first allocation information, the resource is considered to be used for the communication with the child node.

10. The method of claim 1 , wherein the first allocation information and the second allocation information are received from the parent node.

11. The method of claim 1 , wherein the child node is a UE connected to the node.

12. The method of claim 1 , wherein based on the second allocation information informing the particular resource as a hard resource that is always available for communication with the child node, the particular resource is used for the communication with the child node regardless of the first allocation information.

13. A node comprising:

a transceiver to transmit and receive a radio signal; and

a processor coupled with the transceiver to operate,

wherein the processor receives first allocation information related to communication with a parent node and second allocation information related to communication with a child node; and

communicates with the parent node or the child node using a particular resource based on the first allocation information and the second allocation information,

wherein based on the second allocation information informing the particular resource as a soft resource among a hard resource, the soft resource and an unavailable resource and based on no explicit indication that the particular resource is available for the communication with the child node, the particular resource is used for the communication with the parent node.

14. An operating method of a parent node in a wireless communication system, the method comprising:

transmitting first allocation information related to communication with a node and second allocation information related to communication with a child node of the node and the node; and

communicating with the node using a particular resource based on the first allocation information and the second allocation information,

wherein based on the second allocation information informing the particular resource as a soft resource among a hard resource, the soft resource and an unavailable resource and based on no explicit indication that the particular resource is available for the communication with the child node, the particular resource is used for the communication with the parent node.
