Communication device and base station
A communication device includes a receiving unit that receives at least one of configuration information of a same center frequency used for downlink reception and sidelink reception in one slot or configuration information of a same center frequency used for uplink transmission and sidelink transmission in the one slot; and a control unit that configures, based on the received configuration information, at least one of the same center frequency for the downlink reception and the sidelink reception in the one slot or the same center frequency for the uplink transmission and the sidelink transmission in the one slot.
1. A communication device comprising:
a receiver that receives configuration information of a bandwidth part, BWP, to be applied to a sidelink transmission; and
a controller that configures a frequency resource and a subcarrier spacing for the sidelink transmission based on the configuration information of the BWP,
wherein the configuration information of the BWP is configured independently of configuration information of a BWP to be applied to an uplink transmission, and
wherein the subcarrier spacing for the sidelink transmission configured by the controller is the same as a subcarrier spacing for the uplink transmission.
2. The communication device according to claim 1 , wherein a cyclic prefix for the sidelink transmission configured by the controller is the same as a cyclic prefix for the uplink transmission.
3. A communication method executed by a communication device, the method comprising:
receiving configuration information of a bandwidth part, BWP, to be applied to a sidelink transmission; and
configuring a frequency resource and a subcarrier spacing for the sidelink transmission based on the configuration information of the BWP,
wherein the configuration information of the BWP is configured independently of configuration information of a BWP to be applied to an uplink transmission, and
wherein the configured subcarrier spacing for the sidelink transmission is the same as a subcarrier spacing for the uplink transmission.
4. A base station comprising:
a controller that configures configuration information of a bandwidth part, BWP to be applied to a sidelink transmission independently of configuration information for a BWP to be applied to an uplink transmission; and
a transmitter that transmits the configuration information of the BWP to be applied to the sidelink transmission configured by the controller,
wherein the controller controls a configuration of a frequency resource and a subcarrier spacing for the sidelink transmission by the communication device based on the configuration information of the BWP to be applied to the sidelink transmission, and
wherein the subcarrier spacing for the sidelink transmission controlled by the controller is the same as a subcarrier spacing for the uplink transmission.
