Method and apparatus for transmitting or receiving channel state information in wireless communication system

1. A method for reporting, by a user equipment (UE), channel state information (CSI) in a wireless communication system, the method comprising:

receiving configuration information related to a CSI report,

wherein the configuration information includes first information related with a time domain behavior of the CSI report, and

wherein based on the first information, one of (i) periodic, (ii) semi-persistent or (iii) aperiodic is configured as a behavior of the CSI report in the time domain;

receiving second information related with a time domain behavior of the CSI report,

wherein the second information is configured for a time duration including a plurality of specific units based on a specific unit in the time domain;

receiving a reference signal for a CSI measurement;

performing the CSI measurement based on the reference signal; and

reporting the CSI in the time domain based on the first information and the second information,

wherein the second information is configured for the time duration including a plurality of slots based on a slot unit in the time domain,

wherein an offset value per each period for a periodic CSI report behavior is determined based on the second information,

wherein the second information is configured for each slot unit of the plurality of slots, and is in a form of a bitmap,

wherein each bit of the bitmap is related to each specific unit of the plurality of specific units,

wherein the specific unit corresponds to a DRX cycle, and

wherein the CSI report is transmitted in an “on” duration of the DRX cycle related to bits related to 1 in the bitmap.

2. The method of claim 1 ,

wherein the specific unit is one of a slot, a subframe, a half-frame or a frame.

3. The method of claim 1 ,

wherein the time duration is determined based on a number of bits of the bitmap.

4. The method of claim 1 ,

wherein a “periodic” CSI report behavior is configured based on the first information, and

wherein the specific unit has a period as a unit.

5. The method of claim 1 , further comprising:

receiving information for activating the CSI report, based on that a “semi-persistent” CSI report behavior is configured based on the first information.

6. The method of claim 1 ,

wherein an “periodic” CSI report behavior is configured based on the first information, and

wherein an aperiodic CSI report is included in the second information.

7. The method of claim 2 , further comprising:

receiving information for the specific unit.

8. The method of claim 5 ,

wherein the CSI report is terminated based on the second information regardless of a signal that deactivates the CSI report.

9. A user equipment (UE) configured to report channel state information (CSI) in a wireless communication system, the UE comprising:

one or more transceivers;

one or more processors; and

one or more memories storing instructions for operations executed by the one or more processors and connected to the one or more processors,

wherein the operations include:

receiving configuration information related to a CSI report,

wherein the configuration information includes first information related with a time domain behavior of the CSI report, and

wherein based on the first information, one of (i) periodic, (ii) semi-persistent or (iii) aperiodic is configured as a behavior of the CSI report in the time domain;

receiving second information related with a time domain behavior of the CSI report,

wherein the second information is configured for a time duration including a plurality of specific units based on a specific unit in the time domain;

receiving a reference signal for a CSI measurement;

performing the CSI measurement based on the reference signal; and

reporting the CSI in the time domain based on the first information and the second information,

wherein the second information is configured for the time duration including a plurality of slots based on a slot unit in the time domain,

wherein an offset value per each period for a periodic CSI report behavior is determined based on the second information,

wherein the second information is configured for each slot unit of the plurality of slots, and is in a form of a bitmap,

wherein each bit of the bitmap is related to each specific unit of the plurality of specific units,

wherein the specific unit corresponds to a DRX cycle, and

wherein the CSI report is transmitted in an “on” duration of the DRX cycle related to bits related to 1 in the bitmap.

10. A method for receiving, by a base station (BS), channel state information (CSI) in a wireless communication system, the method comprising:

transmitting, to a user equipment (UE), configuration information related to a CSI report,

wherein the configuration information includes first information related with a time domain behavior of the CSI report, and

wherein based on the first information, one of (i) periodic, (ii) semi-persistent or (iii) aperiodic is configured as a behavior of the CSI report in the time domain;

transmitting second information related with a time domain behavior of the CSI report,

wherein the second information is configured for a time duration including a plurality of specific units based on a specific unit in the time domain;

transmitting a reference signal for a CSI measurement; and

receiving CSI in the time domain based on the first information and the second information,

wherein the second information is configured for the time duration including a plurality of slots based on a slot unit in the time domain,

wherein an offset value per each period for a periodic CSI report behavior is determined based on the second information,

wherein the second information is configured for each slot unit of the plurality of slots, and is in a form of a bitmap,

wherein each bit of the bitmap is related to each specific unit of the plurality of specific units,

wherein the specific unit corresponds to a DRX cycle, and

wherein the CSI report is transmitted in an “on” duration of the DRX cycle related to bits related to 1 in the bitmap.
