Abstract
The present invention provides a method of transmitting a channel quality indicator (CQI) in a wireless communication system. The method performed by a user equipment supporting a relatively shorter transmission time interval (S-TTI) than a legacy transmission time interval (L-TTI) includes determining predefined control channel-related overhead depending on whether S-TTI-based communication is performed and transmitting the CQI based on the determined predefined control channel-related overhead. If the S-TTI-based communication is performed the predefined control channel-related overhead is identically determined between an S-TTI including a legacy physical downlink control channel (PDCCH) region and a S-TTI not including a legacy PDCCH region.

Claim
1. A method for transmitting a channel quality indicator (CQI) in a wireless communication system, the method performed by a user equipment (UE), which supports a short transmission time interval (S-TTI) relatively short compared to a legacy transmission time interval (L-TTI), and comprising:
determining overhead related to a predefined control channel based on whether a S-TTI based communication is performed; and transmitting the CQI based on the determined overhead related to the preconfigured control channel, wherein, if the S-TTI based communication is performed, the overhead related to the predefined control channel is equally determined between an S-TTI which includes a legacy physical downlink control channel region (legacy PDCCH region) and an S-TTI which does not include the legacy PDCCH region.
2. The method of claim 1, wherein the predefined control channel is a PDCCH.
3. The method of claim 1, wherein the L-TTI comprises a plurality of S-TTIs.
4. The method of claim 1, wherein the L-TTI is 1 ms.
5. The method of claim 1, wherein if the S-TTI-based communication is performed, the predefined control channel-related overhead is identically determined between a reference resource based on an S-TTI comprising a legacy PDCCH region and a reference resource based on an S-TTI not comprising a legacy PDCCH region.
6. A method for reporting channel state information (CSI) in a wireless communication system, the method performed by a user equipment (UE), which supports a short transmission time interval (S-TTI) relatively short compared to a legacy transmission time interval (L-TTI), and comprising:
receiving downlink control information (DCI); and reporting the CSI which is triggered by the DCI, wherein the CSI is reported based on a transmission mode for a subframe at which the DCI is received.
7. The method of claim 6, wherein the CSI is reported based on a transmission mode for a subframe to which an S-TTI in which the DCI has been received belongs.
8. The method of claim 7, wherein a type of the subframe is one of a multicast broadcast single frequency network (MBSFN) subframe type and a non-MBSFN (NMBSFN) subframe type.
9. The method of claim 8, wherein if the type of the subframe is the MBSFN subframe type and the type of the subframe is the NMBSFN subframe type, different transmission modes are configured.
10. A method for channel state information (CSI) reporting in a wireless communication system, the method performed by a user equipment (UE), which supports a short transmission time interval (S-TTI) relatively short compared to a legacy transmission time interval (L-TTI), and comprising:
determining a CSI reference resource for the CSI reporting; performing the CSI reporting based on the CSI reference resource, wherein the UE determines the CSI reference resource in units of the S-TTI.
11. The method of claim 10, wherein if the CSI reporting is triggered on an S-TTI physical downlink control channel (PDCCH), the CSI reference resource is selected in the S-TTI unit.
12. The method of claim 10, wherein if the CSI reporting is triggered by S-TTI-related CSI reporting triggering DCI, the CSI reference resource is selected in the S-TTI unit.
13. The method of claim 10, wherein if the CSI reporting is transmitted through an S-TTI physical uplink shared channel (PUSCH) or physical uplink control channel (PUCCH), the CSI reference resource is selected in the S-TTI unit.
14. The method of claim 10, wherein CSI reference resource timing related to the CSI reporting is counted in the S-TTI unit.
