User terminal

Abstract

In order to appropriately perform communication even when a random access procedure with fewer steps than the existing steps is performed, one aspect of a user terminal of the present disclosure includes a transmitting section that transmits a first UL signal including a preamble used for random access and a second UL signal including a message, a receiving section that receives a response signal to the first UL signal and the second UL signal after the second UL signal is transmitted, and a control section that controls a transmission by applying at least one of frequency multiplexing and time multiplexing to the first UL signal and the second UL signal.

1 . A user terminal, comprising:
 a transmitting section that transmits a first UL signal including a preamble used for random access and a second UL signal including a message;   a receiving section that receives a response signal to the first UL signal and the second UL signal after the second UL signal is transmitted; and   a control section that controls a transmission by applying at least one of frequency multiplexing and time multiplexing to the first UL signal and the second UL signal.   
     
     
         2 . The user terminal according to  claim 1 , wherein the control section selects a given combination from among combinations of the first UL signal and the second UL signal to which at least one of the frequency multiplexing and the time multiplexing is applied based on a DL signal. 
     
     
         3 . The user terminal according to  claim 1 , wherein when the first UL signal and the second UL signal are time-multiplexed, a transmission duration of the second UL signal is set separately for each first UL signal. 
     
     
         4 . The user terminal according to  claim 1 , wherein when the first UL signal and the second UL signal are time-multiplexed, the transmission duration of the second UL signal is commonly set for a plurality of first UL signals. 
     
     
         5 . The user terminal according to  claim 4 , wherein a given gap interval is set between the first UL signal having latest transmission timing among the plurality of first UL signals and a transmission timing of a second transmission. 
     
     
         6 . The user terminal according to  claim 3 , wherein the gap interval is set between a first UL signal and a second UL signal associated with different DL signals. 
     
     
         7 . The user terminal according to  claim 2 , wherein when the first UL signal and the second UL signal are time-multiplexed, a transmission duration of the second UL signal is set separately for each first UL signal. 
     
     
         8 . The user terminal according to  claim 2 , wherein when the first UL signal and the second UL signal are time-multiplexed, the transmission duration of the second UL signal is commonly set for a plurality of first UL signals. 
     
     
         9 . The user terminal according to  claim 4 , wherein the gap interval is set between a first UL signal and a second UL signal associated with different DL signals. 
     
     
         10 . The user terminal according to  claim 5 , wherein the gap interval is set between a first UL signal and a second UL signal associated with different DL signals.
