Device in wireless communication system and method
First Claim
1. A device on a base station side in a wireless communication system in which there are a primary component carrier on a licensed band and a plurality of secondary component carriers on an unlicensed band, the device comprising:
- a control unit configured to perform, according to an availability detection result for the plurality of secondary component carriers, power adjustment so that predetermined transmission power pre-allocated to one or more unavailable secondary component carriers is allocated to a secondary component carrier to be used among available secondary component carriers; and
a communication unit configured to send a power adjustment result of the control unit to a user equipment, the power adjustment result comprising at least information indicating whether power allocation is changed and an offset amount of the power adjustment,wherein the communication unit is further configured to send uplink scheduling grant signaling for the plurality of secondary component carriers to the user equipment, and receive the availability detection result for the plurality of secondary component carriers reported by the user equipment according to the uplink scheduling grant signaling.

Abstract
A main carrier on a licensed frequency band and a plurality of auxiliary carriers on an unlicensed frequency band exist in a wireless communication system, and a device at a base-station side in the wireless communication system includes: a controller configured to conduct power adjustment according to a result of detecting the usability of the plurality of auxiliary carriers, to enable a predetermined transmission power pre-allocated to one or more unavailable auxiliary carriers to be allocated to an auxiliary carrier to be used in available auxiliary carriers; and a communication unit configured to send a power adjustment result of the control unit to a user equipment, wherein the power adjustment result at least includes information instructing whether the power allocation changes.

12. A device on a user equipment side in a wireless communication system, the device comprising:
-
a receiving unit configured to receive a power adjustment result from a base station, so that predetermined transmission power pre-allocated to one or more unavailable secondary component carriers is allocated to a secondary component carrier to be used among available secondary component carriers, the power adjustment result comprising at least information indicating whether power allocation is changed and an offset amount of the power adjustment; a control unit configured to perform a corresponding operation according to the power adjustment result; a detecting unit configured to detect availability of the plurality of secondary component carriers according to the uplink scheduling grant signaling; and a sending unit configured to send a detection result of the detecting unit to the base station. - View Dependent Claims (13, 14, 15, 16)

17. A method on a base station side in a wireless communication system in which there are a primary component carrier on a licensed band and a plurality of secondary component carriers on an unlicensed band, the method comprising:
-
a control step of performing, according to an availability detection result for the plurality of secondary component carriers, power adjustment so that predetermined transmission power pre-allocated to one or more unavailable secondary component carriers is allocated to a secondary component carrier to be used among available secondary component carriers; and a communication step of sending a power adjustment result to a user equipment, the power adjustment result comprising at least information indicating whether power allocation is changed and an offset amount of the power adjustment, wherein the communication unit is further configured to send uplink scheduling grant signaling for the plurality of secondary component carriers to the user equipment, and receive the availability detection result for the plurality of secondary component carriers reported by the user equipment according to the uplink scheduling grant signaling.
