Abstract
Provided is a mobile station that can appropriately allocate resources in an unlicensed band. In the mobile station (200), on the basis of resource association between an uplink reference signal and another uplink signal different from the reference signal, a control unit (205) determines a frequency resource to be used for uplink transmission. A transmission unit (209) uses the frequency resource to transmit at least one of the reference signal and the other uplink signal.
Claims7
An integrated circuit, comprising:
- reception circuitry, which, in operation, controls receiving control information relating to a first resource used for a sidelink signal other than a reference signal;
- determination circuitry, which, in operation, controls determining the first resource used for the sidelink signal based on the control information, and determines a second resource used for the reference signal,
- wherein the determination circuitry determines the second resource based on the first resource in a first case and determines the second resource without using the first resource in a second case,
- wherein, in the first case, the second resource when the control information indicates a first value for the first resource is different from the second resource when the control information indicates a second value for the first resource;
- and
- transmission circuitry, which, in operation, controls transmitting the reference signal.
A transmission method, comprising:
- receiving control information relating to a first resource used for a sidelink signal other than a reference signal;
- determining the first resource based on the control information, and determining a second resource used for the reference signal,
- wherein the second resource is determined based on the first resource in a first case and is determined without using the first resource in a second case,
- wherein, in the first case, the second resource when the control information indicates a first value for the first resource is different from the second resource when the control information indicates a second value for the first resource;
- and
- transmitting at least one of the sidelink signal or the reference signal.
A communication apparatus, comprising:
- a receiver, which in operation, receives control information relating to a first resource used for a sidelink signal other than a reference signal;
- circuitry, which in operation, determines the first resource based on the control information, and determines a second resource used for the reference signal,
- wherein the second resource is determined based on the first resource in a first case and is determined without using the first resource in a second case,
- wherein, in the first case, the second resource when the control information indicates a first value for the first resource is different from the second resource when the control information indicates a second value for the first resource;
- and
- a transmitter, which in operation, transmits at least one of the sidelink signal or the reference signal.
