Abstract

Claims (16)

1. A terminal comprising:

a receiver configured to receive a parameter related to a DRX (Discontinuous reception) from a base station; and

a processor configured to control an operation of the DRX for each of a plurality of component carriers, based on the parameter and a subcarrier spacing applied to the component carrier,

wherein the receiver is further configured to receive a Physical Sidelink Shared Channel (PSSCH), and

wherein the parameter indicates an active duration, and the processor performs, at a monitoring timing of a control signal in the active duration of the DRX of a component carrier to which a smallest subcarrier spacing is applied from among the plurality of component carriers, monitoring of a control signal in the active duration of the DRX in each of the plurality of component carriers.

2. The terminal according to claim 1 , wherein the parameter indicates the active duration, and

for a component carrier to which a larger subcarrier spacing is applied, the processor configures a shorter active duration of the DRX.

3. The terminal according to claim 1 , wherein the parameter indicates the active duration, and

for a component carrier to which a larger subcarrier spacing is applied, the processor configures a longer monitoring cycle than a monitoring cycle of a control signal, the monitoring cycle being configured in advance in the active duration of the DRX.

4. The terminal according to claim 1 , wherein the parameter indicates a duration from a traffic occurrence to a sleep state, and

for a component carrier to which a larger subcarrier spacing is applied, the processor configures a shorter duration from the traffic occurrence to the sleep state.

5. A communication method causing a terminal to execute:

a receiving procedure for receiving a parameter related to a DRX (Discontinuous reception) from a base station; and

a control procedure for controlling an operation of the DRX for each of a plurality of component carriers, based on the parameter and a subcarrier spacing applied to the component carrier,

wherein the terminal further receives a Physical Sidelink Shared Channel (PSSCH), and

wherein the parameter indicates an active duration, and the terminal performs, at a monitoring timing of a control signal in the active duration of the DRX of a component carrier to which a smallest subcarrier spacing is applied from among the plurality of component carriers, monitoring of a control signal in the active duration of the DRX in each of the plurality of component carriers.
