Abstract: A method for transmitting channel state information (CSI) by a user equipment in a wireless communication system is discussed. The method includes receiving a transmission burst; measuring the CSI based on the transmission burst; and transmitting the measured CSI, wherein the transmission burst is received in at least a first time resource and a second time resource, wherein the first time resource is configured as a first number of orthogonal frequency divisional multiplexing (OFDM) symbols, wherein the second time resource is configured as a second number of OFDM symbols, wherein the first number is smaller than the second number, and wherein the first time resource is considered to be an invalid time resource for the CSI.
