TERMINAL AND RADIO COMMUNICATION METHOD
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.
