Abstract

A terminal that includes a reception unit that receives system information including information used for configuring a first initial downlink bandwidth part, cell-specific information related to configuration of a physical downlink control channel in the first initial downlink bandwidth part, information used for configuring a second initial downlink bandwidth part, and cell-specific information related to configuration of a physical downlink control channel in the second initial downlink bandwidth part, and a control unit that determines a monitoring occasion of a physical downlink control channel for paging based on information related to a synchronization signal and physical broadcast channel block transmitted in the second initial downlink bandwidth part and on an identifier of a search space.

Claims (40)

1 . A wireless communication method of a terminal, the method comprising:

receiving, from a base station, system information including information used for configuring a first initial downlink bandwidth part, cell-specific information used for configuring a physical downlink control channel of the first initial downlink bandwidth part, information used for configuring a second initial downlink bandwidth part, and cell-specific information used for configuring a physical downlink control channel of the second initial downlink bandwidth part; and

in a case where an identifier of a search space for a paging is included in the cell-specific information used for configuring the physical downlink control channel of the second initial downlink bandwidth part, determining a monitoring occasion of the physical downlink control channel for the paging based on the identifier of the search space for the paging and information used for configuring a synchronization signal and physical broadcast channel (SS/PBCH) block transmitted in the second initial downlink bandwidth part.

2 . The wireless communication method according to claim 1 ,

wherein the information used for configuring the SS/PBCH block transmitted in the second initial downlink bandwidth part is included in the system information.

3 . The wireless communication method according to claim 1 , wherein

the information used for configuring the SS/PBCH block transmitted in the second initial downlink bandwidth part includes information related to transmitted SS/PBCH blocks in an SS-burst.

4 . The wireless communication method according to claim 1 , wherein

the information used for configuring the first initial downlink bandwidth part includes information used for indicating a frequency domain location and bandwidth of the first initial downlink bandwidth part and information used for indicating a subcarrier spacing of the first initial downlink bandwidth part, and

the information used for configuring the second initial downlink bandwidth part includes information used for indicating a frequency domain location and bandwidth of the second initial downlink bandwidth part and information used for indicating a subcarrier spacing of the second initial downlink bandwidth part.

5 . The wireless communication method according to claim 1 ,

wherein the information used for configuring the second initial downlink bandwidth part and the cell-specific information used for configuring the physical downlink control channel of the second initial downlink bandwidth part are for a RedCap terminal.

6 . A terminal comprising:

a memory storing instructions; and

one or more processors configured to execute the instructions to:

receive, from a base station, system information including information used for configuring a first initial downlink bandwidth part, cell-specific information used for configuring a physical downlink control channel of the first initial downlink bandwidth part, information used for configuring a second initial downlink bandwidth part, and cell-specific information used for configuring a physical downlink control channel of the second initial downlink bandwidth part; and

in a case where an identifier of a search space for a paging is included in the cell-specific information used for configuring the physical downlink control channel of the second initial downlink bandwidth part, determine a monitoring occasion of the physical downlink control channel for the paging based on the identifier of the search space for the paging and information used for configuring a synchronization signal and physical broadcast channel (SS/PBCH) block transmitted in the second initial downlink bandwidth part.

7 . The terminal according to claim 6 ,

wherein the information used for configuring the SS/PBCH block transmitted in the second initial downlink bandwidth part is included in the system information.

8 . The terminal according to claim 6 , wherein

the information used for configuring the SS/PBCH block transmitted in the second initial downlink bandwidth part includes information related to transmitted SS/PBCH blocks in an SS-burst.

9 . The terminal according to claim 6 , wherein

the information used for configuring the first initial downlink bandwidth part includes information used for indicating a frequency domain location and bandwidth of the first initial downlink bandwidth part and information used for indicating a subcarrier spacing of the first initial downlink bandwidth part, and

the information used for configuring the second initial downlink bandwidth part includes information used for indicating a frequency domain location and bandwidth of the second initial downlink bandwidth part and information used for indicating a subcarrier spacing of the second initial downlink bandwidth part.

10 . The terminal according to claim 6 ,

wherein the information used for configuring the second initial downlink bandwidth part and the cell-specific information used for configuring the physical downlink control channel of the second initial downlink bandwidth part are for a RedCap terminal.

11 . A base station comprising:

a memory storing instructions; and

one or more processors configured to execute the instructions to:

transmit, to a terminal, system information including information used for configuring a first initial downlink bandwidth part, cell-specific information used for configuring a physical downlink control channel of the first initial downlink bandwidth part, information used for configuring a second initial downlink bandwidth part, and cell-specific information used for configuring a physical downlink control channel of the second initial downlink bandwidth part; and

in a case where an identifier of a search space for a paging is included in the cell-specific information used for configuring the physical downlink control channel of the second initial downlink bandwidth part, configure a monitoring occasion of the physical downlink control channel for the paging based on the identifier of the search space for the paging and information used for configuring a synchronization signal and physical broadcast channel (SS/PBCH) block transmitted in the second initial downlink bandwidth part.

12 . The base station according to claim 11 ,

wherein the information used for configuring the SS/PBCH block transmitted in the second initial downlink bandwidth part is included in the system information.

13 . The base station according to claim 11 , wherein

the information used for configuring the SS/PBCH block transmitted in the second initial downlink bandwidth part includes information related to transmitted SS/PBCH blocks in an SS-burst.

14 . The base station according to claim 11 , wherein

the information used for configuring the first initial downlink bandwidth part includes information used for indicating a frequency domain location and bandwidth of the first initial downlink bandwidth part and information used for indicating a subcarrier spacing of the first initial downlink bandwidth part, and

the information used for configuring the second initial downlink bandwidth part includes information used for indicating a frequency domain location and bandwidth of the second initial downlink bandwidth part and information used for indicating a subcarrier spacing of the second initial downlink bandwidth part.

15 . The base station according to claim 11 ,

wherein the information used for configuring the second initial downlink bandwidth part and the cell-specific information used for configuring the physical downlink control channel of the second initial downlink bandwidth part are for a RedCap terminal.
