Abstract:
The present invention is designed to set forth a method that can prevent demodulation errors in user terminals and make maximum use of resources when data transmission is carried out by using only part of the OFDM symbols in subframes. A user terminal according to an example of the present invention has a receiving section that receives information about the number of symbols used in a given subframe of a carrier where LBT (Listen Before Talk) is configured, in the carrier, and a control section that controls a receiving process in the given subframe based on the information about the number of symbols used.
