Method and device for performing communication with a parent node or child node based on first and second allocation information

1. A method performed by a node operating 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

performing communication with the parent node or communication with the child node based on the first and the second allocation information,

wherein, based on the second allocation information informing a specific resource as a hard resource among the hard resource, a soft resource and an unavailable resource, the specific resource is used for communication with the child node irrespective of the first allocation information,

wherein the second allocation information informs a resource type of the specific resource as one of hard downlink, soft downlink, hard uplink, soft uplink, hard flexible, soft flexible, and unavailable, and

wherein the second allocation information informing the resource type as unavailable indicates that the specific resource is a resource that is not used in a relationship between the node and the child node.

2. The method of claim 1 , wherein the first allocation information informs of resource type of the specific resource as one of downlink, uplink, and flexible.

3. The method of claim 1 , wherein the second allocation information informing the resource type as hard downlink indicates that the specific resource is a resource which can be always available for the node to transmit a signal to the child node, and

wherein the second allocation information informing the resource type as soft downlink indicates that the specific resource is a resource for which transmission of a signal by the node to the child node is controlled by the parent node.

4. The method of claim 1 , wherein the second allocation information informing the resource type as hard uplink indicates that the specific resource is a resource which can be always available for the node to receive a signal from the child node, and

wherein the second allocation information informing the resource type as soft uplink indicates that the specific resource is a resource for which reception of a signal by the node from the child node is controlled by the parent node.

5. The method of claim 1 , wherein the second allocation information informing the resource type as hard flexible indicates that the specific resource is always a flexible resource in a relationship between the node and the child node, and

wherein the second allocation information informing the resource type as soft flexible indicates that the specific resource is a resource for which whether the specific resource is a flexible resource in a relationship between the node and the child node is controlled by the parent node.

6. The method of claim 1 , wherein the second allocation information informing the resource type as unavailable indicates that the specific resource is a resource that is not used in a relationship between the node and the child node.

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

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

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

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

11. The method of claim 1 , wherein, based on the second allocation information informing a resource type of a resource as soft downlink, soft uplink, or soft flexible, based on no particular explicit or implicit indication about availability of the resource for communication with the child node being provided, the resource is used for communication with the parent node.

12. A node, comprising:

a transceiver transmitting and receiving a radio signal; and

a processor operating in conjunction with the transceiver,

wherein the processor is configured to:

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

perform communication with the parent node or communication with the child node based on the first and the second allocation information,

wherein, based on the second allocation information informing a specific resource as a hard resource among the hard resource, a soft resource and an unavailable resource, the specific resource is used for communication with the child node irrespective of the first allocation information,

wherein the second allocation information informs a resource type of the specific resource as one of hard downlink, soft downlink, hard uplink, soft uplink, hard flexible, soft flexible, and unavailable, and

wherein the second allocation information informing the resource type as unavailable indicates that the specific resource is a resource that is not used in a relationship between the node and the child node.

13. The node of claim 12 , wherein the first allocation information informs a resource type of the specific resource as one of downlink, uplink, and flexible.

14. The node of claim 12 , wherein the second allocation information informing the resource type as hard downlink indicates that the specific resource is a resource which can be always available for the node to transmit a signal to the child node, and

wherein the second allocation information informing the resource type as soft downlink indicates that the specific resource is a resource for which transmission of a signal by the node to the child node is controlled by the parent node.

15. The node of claim 12 , wherein the second allocation information informing the resource type as hard uplink indicates that the specific resource is a resource which can be always available for the node to receive a signal from the child node, and

wherein the second allocation information informing the resource type as soft uplink indicates that the specific resource is a resource for which reception of a signal by the node from the child node is controlled by the parent node.

16. The node of claim 12 , wherein the second allocation information informing the resource type as hard flexible indicates that the specific resource is always a flexible resource in a relationship between the node and the child node, and

wherein the second allocation information informing the resource type as soft flexible indicates that the specific resource is a resource for which whether the specific resource is a flexible resource in a relationship between the node and the child node is controlled by the parent node.

17. The node of claim 12 , wherein the first and the second allocation information are received from the parent node.

18. An apparatus configured to control a node to operate in a wireless communication system, the apparatus comprising:

at least one processor; and

at least one computer memory operably connectable to the at least one processor and storing instructions that, when executed by the at least one processor, perform operations comprising:

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

performing communication with the parent node or communication with the child node based on the first and the second allocation information,

wherein, based on the second allocation information informing a specific resource as a hard resource among the hard resource, a soft resource and an unavailable resource, the specific resource is used for communication with the child node irrespective of the first allocation information,

wherein the second allocation information informs a resource type of the specific resource as one of hard downlink, soft downlink, hard uplink, soft uplink, hard flexible, soft flexible, and unavailable, and
