Terminal and radio communication method

Abstract

A terminal according to one aspect of the present disclosure includes a receiving section that receives a physical downlink shared channel (PDSCH) scheduled with use of a specific type of radio network temporary identifier (RNTI), and a control section that uses a value associated with the specific type as a ratio between energy of the PDSCH and energy of a reference signal associated with the PDSCH. According to one aspect of the present disclosure, it is possible to appropriately receive multicast transmission transmitted with use of a PDSCH.

1 . A terminal comprising:
 a receiving section that receives a physical downlink shared channel (PDSCH) scheduled with use of a specific type of radio network temporary identifier (RNTI); and   a control section that uses a value associated with the specific type as a ratio between energy of the PDSCH and energy of a reference signal associated with the PDSCH.   
     
     
         2 . The terminal according to  claim 1 , wherein
 the value is defined or configured separately from a value associated with a type other than the specific type.   
     
     
         3 . The terminal according to  claim 1 , wherein
 the reference signal is a demodulation reference signal (DM-RS), and   a candidate for the value is associated with a type of RNTI used for scheduling of the PDSCH, the number of DM-RS code division multiplexing (CDM) groups without data, and a DM-RS configuration type.   
     
     
         4 . The terminal according to  claim 1 , wherein
 the reference signal is a phase-tracking reference signal (PT-RS), and   existence of the PT-RS is configured for the control section by higher layer signaling.   
     
     
         5 . The terminal according to  claim 4 , wherein
 a candidate for the value is associated with a type of RNTI used for scheduling of the PDSCH, a higher layer parameter, and the number of PDSCH layers.   
     
     
         6 . A radio communication method for a terminal, the radio communication method comprising:
 receiving a physical downlink shared channel (PDSCH) scheduled with use of a specific type of radio network temporary identifier (RNTI); and   using a value associated with the specific type as a ratio between energy of the PDSCH and energy of a reference signal associated with the PDSCH.   
     
     
         7 . The terminal according to  claim 2 , wherein
 the reference signal is a demodulation reference signal (DM-RS), and   a candidate for the value is associated with a type of RNTI used for scheduling of the PDSCH, the number of DM-RS code division multiplexing (CDM) groups without data, and a DM-RS configuration type.   
     
     
         8 . The terminal according to  claim 2 , wherein
 the reference signal is a phase-tracking reference signal (PT-RS), and   existence of the PT-RS is configured for the control section by higher layer signaling.   
     
     
         9 . The terminal according to  claim 3 , wherein
 the reference signal is a phase-tracking reference signal (PT-RS), and   existence of the PT-RS is configured for the control section by higher layer signaling.
