Method for performing detection by node in wireless communication system and node using same method
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.
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.
