Abstract
[Object] To provide a mechanism in which Listen-Before-Talk (LBT) can be efficiently executed using a millimeter-wave band. [Solution] An apparatus including: a processing unit configured to infer, on a basis of a result of LBT related to at least one first unit frequency band included in a group that includes a plurality of unit frequency bands, a result of LBT related to a second unit frequency band other than the first unit frequency band included in the group.
Claims20
An apparatus, comprising:
- processing circuitry configured to
- measure a reception power of Listen-Before-Talk (LBT) of a first unit frequency band included in a plurality of unit frequency bands;
- determine a first result of the LBT based on the reception power of the LBT of the first unit frequency band, the first result indicating a status of the first unit frequency band;
- and
- determine, in response to the first result indicating that the first unit frequency band is in an idle state or in a busy state, a second result of LBT, the second result indicating a status of a second unit frequency band, wherein
- the second unit frequency band is different than the first unit frequency band and is included in the plurality of unit frequency bands,
- in a case that the first result indicates that the first unit frequency band is in the idle state, the processing circuitry determines the second result to indicate that the second unit frequency band is in the idle state and transmits signals using the first and second unit frequency bands to a base station, and
- in a case that the first result indicates that the first unit frequency band is in the busy state, the processing circuitry determines the second result to indicate that the second unit frequency band is in the busy state and does not transmit signals using the first and second unit frequency bands to the base station.

A method, comprising:
- measuring, by processing circuitry of a terminal device, a reception power of Listen-Before-Talk (LBT) of a first unit frequency band included in a plurality of unit frequency bands;
- determining a first result of the LBT based on the reception power of the LBT of the first unit frequency band, the first result indicating a status of the first unit frequency band;
- and
- determining, by the processing circuitry and in response to the first result indicating that the first unit frequency band is in an idle state or in a busy state, a second result of LBT, the second result indicating a status of a second unit frequency band, wherein
- the second unit frequency band is different than the first unit frequency band and is included in the plurality of unit frequency bands, and
- determining the second result comprises:
- in a case that the first result indicates that the first unit frequency band is in the idle state, determining the second result to indicate that the second unit frequency band is in the idle state and transmitting signals using the first and second unit frequency bands to a base station, and
- in a case that the first result indicates that the first unit frequency band is in the busy state, determining the second result to indicate that the second unit frequency band is in the busy state and not transmitting signals using the first and second unit frequency bands to the base station.
