Terminal, radio communication method, base station, and system
A terminal, as disclosed, includes: a receiver that receives a downlink control information (DCI) using a specific type of radio network temporary identifier (RNTI); and a processor that controls reception of a physical downlink shared channel (PDSCH) scheduled by the DCI, based on a configuration associated with the specific type. In other aspects, a radio communication method, a base station, and a system are also disclosed.
1. A terminal comprising:
a receiver that receives a downlink control information (DCI) using a specific type of radio network temporary identifier (RNTI) for scheduling a multicast physical downlink shared channel (PDSCH); and
a processor that determines a ratio between energy of the multicast PDSCH and energy of a demodulation reference signal (DM-RS) for the multicast PDSCH, based on a number of DM-RS code division multiplexing (CDM) groups without data for the multicast PDSCH.
2. The terminal according to claim 1 , wherein the receiver receives a configuration for the multicast PDSCH, and the configuration is configured separately from a configuration for a unicast PDSCH.
3. The terminal according to claim 1 , wherein
a range of the number of DM-RS CDM groups without data for the multicast PDSCH is different from a range of a number of DM-RS CDM groups without data for a unicast PDSCH.
4. A radio communication method for a terminal, the method comprising:
receiving a downlink control information (DCI) using a specific type of radio network temporary identifier (RNTI) for scheduling a multicast physical downlink shared channel (PDSCH); and
determining a ratio between energy of the multicast PDSCH and energy of a demodulation reference signal (DM-RS) for the multicast PDSCH, based on a number of DM-RS code division multiplexing (CDM) groups without data for the multicast PDSCH.
5. A base station comprising:
a transmitter that transmits a downlink control information (DCI) using a specific type of radio network temporary identifier (RNTI) for scheduling a multicast physical downlink shared channel (PDSCH); and
a processor that determines a ratio between energy of the multicast PDSCH and energy of a demodulation reference signal (DM-RS) for the multicast PDSCH, based on a number of DM-RS code division multiplexing (CDM) groups without data for the multicast PDSCH.
6. A system comprising:
a terminal that comprises:
a receiver that receives a downlink control information (DCI) using a specific type of radio network temporary identifier (RNTI) for scheduling a multicast physical downlink shared channel (PDSCH); and
a processor that determines a ratio between energy of the multicast PDSCH and energy of a demodulation reference signal (DM-RS) for the multicast PDSCH, based on a number of DM-RS code division multiplexing (CDM) groups without data for the multicast PDSCH; and
a base station that transmits the DCI.
