Abstract
Provided are a method for reporting channel state information (CSI) and a device using the same. The device determines a CSI payload size in a CSI triggering subframe on which a CSI report is triggered. The device selects one of a plurality of physical uplink control channel (PUCCH) formats according to the CSI payload size.
Claims12
A method of reporting channel state information (CSI) in a wireless communication system, the method comprising:
- receiving, by a wireless device, a configuration for a plurality of physical uplink control channel (PUCCH) formats;
- determining, by the wireless device, a CSI payload size in a CSI triggering subframe in which a CSI report is triggered;
- selecting, by the wireless device, one of the plurality of PUCCH formats according to the CSI payload size;
- and
- transmitting, by the wireless device, the CSI report through the selected PUCCH format in the CSI triggering subframe.
