Method and device for remote interference management in wireless communication system
The present disclosure provides a method and a device for performing remote interference management. The method comprises receiving, from a victim gNB, at least one RIM-reference signal (RS); transmitting, from a distributed unit (DU) of the aggressor gNB to a central unit (CU) of the aggressor gNB, a message comprising RIM information; and determining to stop monitoring the at least one RIM-RS based on the RIM information.
1. A method, performed by an aggressor base station (gNB) of for a remote interference management (RIM), the method comprising:
receiving, from a victim gNB, at least one RIM-reference signal (RS);
transmitting, from a distributed unit (DU) of the aggressor gNB to a central unit (CU) of the aggressor gNB, a message comprising RIM information; and
determining to stop monitoring the at least one RIM-RS based on the RIM information,
wherein the RIM information comprises a Victim gNB set ID, status information on the at least one RIM-RS, and information on an aggressor cell on which the at least one RIM-RS is detected, and
wherein the status information on the at least one RIM-RS comprises RIM-RS status information comprising RIM-RS disappearance or RIM-RS detected.
2. The method of claim 1 ,
wherein the Victim gNB set ID is used to identify a group of gNBs which transmit a same RIM-RS.
3. The method of claim 1 ,
wherein the information on the aggressor cell is related to at least one Cell Global Identifier (CGI).
4. The method of claim 1 ,
wherein the determining to stop monitoring comprises stopping monitoring when the status information on the at least one RIM-RS comprises the RIM-RS disappearance.
5. An aggressor base station (gNB) for performing a remote interference management (RIM), the aggressor gNB comprising:
a transceiver; and
at least one processor coupled with the transceiver and configured to:
receive, from a victim gNB, at least one RIM-reference signal (RS);
transmit, from a distributed unit (DU) of the aggressor gNB to a central unit (CU) of the aggressor gNB, a message comprising RIM information; and
determine to stop monitoring the at least one RIM-RS based on the RIM information,
wherein the RIM information comprises a Victim gNB set ID, status information on the at least one RIM-RS, and information on an aggressor cell on which the at least one RIM-RS is detected, and
wherein the status information on the at least one RIM-RS comprises RIM-RS disappearance or RIM-RS detected.
6. The aggressor gNB of claim 5 ,
wherein the Victim gNB set ID is used to identify a group of gNBs which transmit a same RIM-RS.
7. The aggressor gNB of claim 5 ,
wherein the information on the aggressor cell is related to at least one Cell Global Identifier (CGI).
8. The aggressor gNB of claim 5 ,
wherein the at least one processor is further configured to stop monitoring when the status information on the at least one RIM-RS comprises the RIM-RS disappearance.
9. A method, performed by a victim base station (gNB) for a remote interference management (RIM), the method comprising:
transmitting, to an aggressor gNB, at least one RIM-reference signal (RS);
transmitting, from a central unit (CU) of the victim gNB to a distributed unit (DU) of the victim gNB, a message comprising RIM information; and
determining to stop transmitting the at least one RIM-RS based on the RIM information,
wherein the RIM information comprises a Victim gNB set ID, status information on the at least one RIM-RS comprising RIM-RS disappearance or RIM-RS detected.
10. The method of claim 9 ,
wherein the Victim gNB set ID is used to identify a group of gNBs which transmit a same RIM-RS.
11. The method of claim 9 ,
wherein the determining to stop transmitting comprises stopping transmitting when the status information on the at least one RIM-RS comprises the RIM-RS disappearance.
12. A victim base station (gNB) for performing a remote interference management (RIM), the victim gNB comprising:
a transceiver; and
at least one processor coupled with the transceiver and configured to:
transmit, to an aggressor gNB, at least one RIM-reference signal (RS);
transmit, from a central unit (CU) of the victim gNB to a distributed unit (DU) of the victim gNB, a message comprising RIM information; and
determine to stop transmitting the at least one RIM-RS based on the RIM information,
wherein the RIM information comprises a Victim gNB set ID, status information on the at least one RIM-RS comprising RIM-RS disappearance or RIM-RS detected.
13. The victim gNB of claim 12 ,
wherein the Victim gNB set ID is used to identify a group of gNBs which transmit a same RIM-RS.
14. The victim gNB of claim 12 ,
wherein the at least one processor is further configured to stop transmitting when the status information on the at least one RIM-RS comprises the RIM-RS disappearance.
