Method for interference measurement in wireless communication system and apparatus for same
A method for measuring interference by a terminal in a wireless communication system according to one embodiment of the present invention may comprise the steps of: receiving interference measurement configuration information including a semi-persistence channel state information-interference (CSI-IM) configuration; receiving a request which indicates measurement of the semi-persistence CSI-IM configuration; and measuring the semi-persistence CSI-IM configuration in response to the received request, wherein the semi-persistence CSI-IM configuration may indicate CSI-IM which is performed at predetermined periods during a predetermined time interval.
1. A method for measuring interference in a wireless communication system, performed by a terminal, the method comprising:
receiving first information for configuring one or more resources for a semi-persistent interference measurement;
receiving second information for either enabling or disabling the terminal to perform the semi-persistent interference measurement in the one or more resources; and
performing the semi-persistent interference measurement for the one or more resources configured by the first information, based on the second information,
wherein the first information includes a periodicity of the one or more resources, and
wherein the configuration of the one or more resources is applied after a specific time duration from a timing related to reception of the second information.
2. The method according to claim 1 , wherein the second information includes a channel state information (CSI) report request, or the second information is received together with the CSI report request.
3. The method according to claim 1 , wherein in a case that the semi-persistent interference measurement is to be reported in a subframe #m+k after a predetermined number of (k) subframes from a subframe #m in which the second information is received:
based on the second information being received before a channel state information (CSI) report request is received:
a report of the semi-persistent interference measurement related to the CSI report request received in the subframe #m+k or in a subsequent subframe is omitted.
4. A terminal configured to measure interference in a wireless communication system, the terminal comprising:
a transmitter and a receiver;
at least one processor; and
at least one computer memory connected to the at least one processor and storing instructions that, based on being executed by the at least one processor, perform operations comprising:
receiving first information for configuring one or more resources for a semi-persistent interference measurement;
receiving second information for either enabling or disabling the terminal to perform the semi-persistent interference measurement in the one or more resources; and performing the semi-persistent interference measurement for the one or more resources configured by the first information, based on the second information,
wherein the first information includes a periodicity of the one or more resources, and
wherein the configuration of the one or more resources is applied after a specific time duration from a timing related to reception of the second information.
5. The terminal according to claim 4 , wherein the second information includes a channel state information (CSI) report request, or the second information is received together with the CSI report request.
6. The terminal according to claim 4 , wherein in a case measurement is to be reported in a subframe #m+k after a predetermined number of (k) subframes from a subframe #m in which the second information is received:
based on the second information being received before a channel state information (CSI) report request is received:
a report of the semi-persistent interference measurement related to the CSI report request received in the subframe #m+k or in a subsequent subframe is omitted.
7. A processing device configured to control a terminal to measure interference in a wireless communication system, the processing device comprising:
at least one processor; and
at least one computer memory connected to the at least one processor and storing instructions that, based on being executed by the at least one processor, perform operations comprising:
receiving first information for configuring one or more resources for a semi-persistent interference measurement;
receiving second information for either enabling or disabling the terminal to perform the semi-persistent interference measurement in the one or more resources; and
performing the semi-persistent interference measurement for the one or more resources configured by the first information, based on the second information,
wherein the first information includes a periodicity of the one or more resources, and
wherein the configuration of the one or more resources is applied after a specific time duration from a timing related to reception of the second information.
8. The processing device according to claim 7 , wherein the second information includes a channel state information (CSI) report request, or the second information is received together with the CSI report request.
9. The processing device according to claim 7 , wherein in a case that the semi-persistent interference measurement is to be reported in a subframe #m+k after a predetermined number of (k) subframes from a subframe #m in which the second information is received:
based on the second information being received before a channel state information (CSI report request is received:
a report of the semi-persistent interference measurement related to the CSI report request received in the subframe #m+k or in a subsequent subframe is omitted.
