Abstract
A terminal according to one aspect of the present disclosure includes: a control section that judges allocation of a downlink shared channel or a reference signal for the downlink shared channel, based on at least one of a cell index, a control resource set pool index, and a group index configured for a control resource set to which each of the synchronization signal block and the downlink shared channel corresponds; and a reception section that receives at least one of the synchronization signal block and the downlink shared channel.
Claims4
A terminal comprising:
- a processor that determines an allocation of a demodulation reference signal (DM-RS) for a physical downlink shared channel (PDSCH) based on physical cell IDs to which a synchronization signal/physical broadcast channel (SS/PBCH) block and the PDSCH correspond;
- and
- a receiver that receives at least one of the SS/PBCH block and the DM-RS for the PDSCH,
- wherein if the SS/PBCH block and the PDSCH are transmitted from a same cell, the processor does not expect to receive the DM-RS for the PDSCH in a resource element that overlaps with a resource element for the SS/PBCH block, and
- wherein if the SS/PBCH block and the PDSCH are transmitted from different cells, the PDSCH is associated with a transmission configuration indication (TCI) state.
A radio communication method for a terminal, comprising:
- determining an allocation of a demodulation reference signal (DM-RS) for a physical downlink shared channel (PDSCH) based on physical cell IDs to which a synchronization signal/physical broadcast channel (SS/PBCH) block and the PDSCH correspond;
- and
- receiving at least one of the SS/PBCH block and the DM-RS for the PDSCH,
- wherein if the SS/PBCH block and the PDSCH are transmitted from a same cell, the DM-RS for the PDSCH is not expected to be received in a resource element that overlaps with a resource element for the SS/PBCH block, and
- wherein if the SS/PBCH block and the PDSCH are transmitted from different cells, the PDSCH is associated with a transmission configuration indication (TCI) state.
A system comprising:
- a terminal;
- and
- a base station;
- wherein the terminal comprises:
- a processor that determines an allocation of a demodulation reference signal (DM-RS) for a physical downlink shared channel (PDSCH) based on physical cell IDs to which a synchronization signal/physical broadcast channel (SS/PBCH) block and the PDSCH correspond;
- and
- a receiver that receives at least one of the SS/PBCH block and the DM-RS for the PDSCH,
- wherein if the SS/PBCH block and the PDSCH are transmitted from a same cell, the processor does not expect to receive the DM-RS for the PDSCH in a resource element that overlaps with a resource element for the SS/PBCH block, and
- wherein if the SS/PBCH block and the PDSCH are transmitted from different cells, the PDSCH is associated with a transmission configuration indication (TCI) state, and
- the base station comprises:
- a transmitter that transmits at least one of the SS/PBCH block and the DM-RS for the PDSCH.
