Terminal, base station and communication method
Provided is a terminal having: a controlling unit configured to determine a subcarrier spacing to be applied to a physical uplink control channel satisfying a bandwidth and map the physical uplink control channel to a physical resource; and a transmitting unit configured to transmit the physical resource to a base station.
1 . A terminal comprising:
a receiving unit configured to receive information indicating a number of resource blocks to be allocated to a format of a physical uplink control channel from a base station;
a controlling unit configured to map the physical uplink control channel to a physical resource of the number of resource blocks; and
a transmitting unit configured to transmit the physical uplink control channel to the base station using the physical resource, wherein
the transmitting unit transmits information to the base station indicating whether or not an allocation of a plurality of resource blocks to the physical uplink control channel is supported in each of a plurality of subcarrier spacings that includes possible values of 120 kHz, 480 kHz, and 960 kHz for the plurality of subcarrier spacings.
2 . A communication system comprising: a terminal; and a base station, wherein
the terminal includes:
a receiving unit configured to receive information indicating a number of resource blocks to be allocated to a format of a physical uplink control channel from the base station;
a controlling unit configured to map the physical uplink control channel to a physical resource of the number of resource blocks; and
a transmitting unit configured to transmit the physical uplink control channel to the base station using the physical resource, wherein
the transmitting unit transmits information to the base station indicating whether or not an allocation of a plurality of resource blocks to the physical uplink control channel is supported in each of a plurality of subcarrier spacings that includes possible values of 120 kHz, 480 kHz, and 960 kHz for the plurality of subcarrier spacings, and
the base station includes:
a transmitting unit configured to transmit the information indicating the number of resource blocks to be allocated to the physical uplink control channel to the terminal;
a controlling unit configured to assume that the physical uplink control channel is to be mapped to a physical resource of the number of resource blocks; and
a receiving unit configured to receive the physical uplink control channel from the terminal using the physical resource, wherein
the receiving unit receives information indicating whether or not an allocation of a plurality of resource blocks to the physical uplink control channel is supported in each of a plurality of subcarrier spacings from the terminal.
3 . A communication method performed by a terminal, the communication method comprising:
receiving information indicating a number of resource blocks to be allocated to a format of a physical uplink control channel from a base station;
mapping the physical uplink control channel to a physical resource of the number of resource blocks;
transmitting the physical uplink control channel to the base station using the physical resource; and
transmitting information to the base station indicating whether or not an allocation of a plurality of resource blocks to the physical uplink control channel is supported in each of a plurality of subcarrier spacings that includes possible values of 120 kHz, 480 kHz, and 960 kHz for the plurality of subcarrier spacings.
