Abstract
The present disclosure relates to a method and an apparatus for uplink data scheduling of a cell using an unlicensed spectrum. The method may include configuring carrier aggregation including a secondary cell (SCell) using an unlicensed spectrum, receiving downlink control information including subframe allocation information for transmitting uplink data in the secondary cell from a base station, and transmitting the uplink data through a plurality of consecutive subframes based on the subframe allocation information.
Claims15
A method for transmitting uplink data by a user equipment, the method comprising:
- configuring carrier aggregation including a secondary cell which is using an unlicensed spectrum;
- receiving downlink control information including subframe allocation information for transmitting uplink data in the secondary cell from a base station;
- and
- transmitting the uplink data through a plurality of consecutive subframes of the secondary cell based on the subframe allocation information.
A method for receiving uplink data by a base station, the method comprising:
- controlling carrier aggregation configuration of a user equipment including a secondary cell which is using an unlicensed spectrum;
- transmitting downlink control information including subframe allocation information for transmitting uplink data in the secondary cell;
- and
- receiving the uplink data transmitted through a plurality of consecutive subframes of the secondary cell based on the subframe allocation information.
A user equipment for transmitting uplink data, the user equipment comprising:
- a controller configured to configure carrier aggregation including a secondary cell which is using an unlicensed spectrum;
- a receiver configured to receive downlink control information including subframe allocation information for transmitting a uplink data in the secondary cell from a base station;
- and
- a transmitter configured to transmit the uplink data through a plurality of consecutive subframes of the secondary cell based on the subframe allocation information.
