Abstract

Proposed is a method for performing detection by a first node in a wireless communication system. The method comprises: receiving detection configuration information from a second node; and when detection request information is received from the second node, transmitting a detection signal to a neighboring node on the basis of the detection configuration information, wherein the detection signal is aperiodically transmitted and is transmitted on the basis of beam sweeping.

First claim

What is claimed is:

1. A method for transmitting a synchronization signal block (SSB) in a wireless communication system, the method performed by a node and comprising:
receiving a plurality of SSB transmission configurations (STCs) determined by a donor node, wherein each of the plurality of STCs informs a periodicity and an offset for a related SSB, and
transmitting the related SSB based on the plurality of STCs,
wherein the related SSB is used for discovery and measurement related to a child node of the node.

2. The method of claim 1 , wherein the node receives the plurality of STCs from a parent node of the node.

3. The method of claim 1 , wherein at least one of the periodicity and the offset of the related SSB is different per the plurality of STCs.

4. The method of claim 3 , wherein the at least one of the periodicity and the offset is different according to a different target node.

5. The method of claim 1 , wherein the node receives discovery request information, and
wherein the node transmits the related SSB based on the discovery request information.

6. The method of claim 5 , wherein the discovery request information is cell-specific or group-specific.

7. The method of claim 1 , wherein the related SSB includes an identifier (ID) of the node.

8. The method of claim 1 , wherein the plurality of STCs is transmitted through system information or a radio resource control (RRC) message.

9. The method of claim 1 , wherein the at least one related SSB is transmitted based on time division multiplexing (TDM) manner or frequency division multiplexing (FDM) manner.

10. The method of claim 1 , wherein the child node is a user equipment (UE) or another node.

11. The method of claim 1 , wherein each of the plurality of STCs includes an index for the related SSB, and
wherein the index identifies a beam direction for the related SSB.

12. The method of claim 11 , wherein the node transmits the related SSB based on the beam direction.

13. The method of claim 1 , wherein the node is a node on integrated access backhaul links (IAB) system.

14. A node, comprising:
a transceiver transmitting and receiving radio signals; and
a processor being operatively connected to the transceiver,
wherein the processor is configured to:
receive a plurality of SSB transmission configurations (STCs) determined by a donor node, wherein each of the plurality of STCs informs a periodicity and an offset for a related SSB, and
transmit the related SSB based on the plurality of STCs,
wherein the related SSB is used for discovery and measurement related to a child node of the node.
