Method and apparatus for channel state information report in wireless communication system
A method and an apparatus for channel state information report (CSI report) in a wireless communication system are disclosed. A method performed by a terminal in a wireless communication system according to an embodiment of the present disclosure may comprise: receiving, from a network, configuration information related to N reporting settings and a plurality of CSI-RS resources, wherein the N is an integer greater than or equal to 1; receiving, from the network, triggering information indicating at least one reporting setting among the N reporting settings; and transmitting, to the network, a single CSI based on a plurality of time instances of the plurality of CSI-RS resources, in response to the triggering information. Here, the plurality of time instances may be related to the at least one reporting setting.
1 . A method comprising:
transmitting configuration information related to N reporting settings, wherein the Nis an integer greater than or equal to 1;
transmitting triggering information indicating at least one reporting setting among the N reporting settings; and
in response to the triggering information, receiving a single channel station information (CSI) based on a plurality of measurement resources related to the at least one reporting setting,
wherein, based on a CSI reference signal (CSI-RS) resource indicator (CRI) being not configured as report information by the at least one reporting setting, the plurality of measurement resources are interpreted as being configured for one CSI-RS resource over a plurality of time instances, and
wherein the plurality of time instances are configured using a plurality of triggering offsets related to the at least one reporting setting based on a timing of the triggering information.
2 . The method of claim 1 ,
wherein, based on one reporting setting being triggered by the triggering information, the plurality of measurement resources are configured through one resource set associated with the one reporting setting.
3 . The method of claim 2 ,
wherein a configuration for the one resource set includes information for the plurality of triggering offsets.
4 . The method of claim 1 ,
wherein, based on one reporting setting being triggered by the triggering information, the plurality of measurement resources are configured through a plurality of resource sets associated with the one reporting setting.
5 . The method of claim 4 ,
wherein a configuration for each of the plurality of resource sets includes information for one triggering offset.
6 . The method of claim 1 ,
wherein, based on a plurality of reporting settings being triggered by the triggering information, the plurality of measurement resources are configured through the plurality of reporting setting.
7 . The method of claim 1 ,
wherein information for whether a user equipment performs calculation of the single CSI based on the plurality of measurement resources is indicated by a network.
8 . The method of claim 1 ,
wherein the plurality of time instances are configured in units of transmission time intervals.
9 . An apparatus comprising:
at least one transceiver; and
at least one processor coupled with the at least one transceiver,
wherein the at least one processor is configured to:
receive configuration information related to N reporting settings, wherein the Nis an integer greater than or equal to 1;
receive triggering information indicating at least one reporting setting among the N reporting settings; and
in response to the triggering information, transmit a single channel station information (CSI) based on a plurality of measurement resources,
wherein, based on a CSI reference signal (CSI-RS) resource indicator (CRI) being not configured as report information by the at least one reporting setting, the plurality of measurement resources are interpreted as being configured for one CSI-RS resource over a plurality of time instances, and
wherein the plurality of time instances are configured using a plurality of triggering offsets related to the at least one reporting setting based on a timing of the triggering information.
10 . An apparatus comprising:
at least one transceiver; and
at least one processor coupled with the at least one transceiver,
wherein the at least one processor is configured to:
transmit configuration information related to N reporting settings, wherein the Nis an integer greater than or equal to 1;
transmit triggering information indicating at least one reporting setting among the N reporting settings; and
in response to the triggering information, receive a single channel station information (CSI) based on a plurality of measurement resources,
wherein, based on a CSI reference signal (CSI-RS) resource indicator (CRI) being not configured as report information by the at least one reporting setting, the plurality of measurement resources are interpreted as being configured for one CSI-RS resource over a plurality of time instances, and
wherein the plurality of time instances are configured using a plurality of triggering offsets related to the at least one reporting setting based on a timing of the triggering information.
