Abstract
A user terminal includes: a receiver configured to receive multicast/broadcast data transmitted from a base station to a plurality of user terminals using the same downlink radio resources; a controller configured to select uplink radio resources to be used for transmission of feedback information, from a resource pool allocated from the base station to a group including the plurality of user terminals; and a transmitter configured to transmit the feedback information to the base station using the selected uplink radio resources.

A user terminal, comprising:
- a receiver configured to receive multicast/broadcast data transmitted from a base station to a plurality of user terminals using the same downlink radio resources;
- a controller configured to select uplink radio resources to be used for transmission of feedback information, from a resource pool allocated from the base station to a group including the plurality of user terminals;
- and
- a transmitter configured to transmit the feedback information to the base station using the selected uplink radio resources.
A base station, comprising:
- a controller configured to allocate a resource pool usable for transmission of feedback information to a group including a plurality of user terminals;
- a transmitter configured to transmit multicast/broadcast data to the plurality of user terminals using the same downlink radio resources;
- and
- a receiver configured to receive the feedback information transmitted from the plurality of user terminals using uplink radio resources selected from the resource pool.
A method for a user terminal, comprising:
- receiving multicast/broadcast data transmitted from a base station to a plurality of user terminals using the same downlink radio resources;
- selecting uplink radio resources to be used for transmission of feedback information, from a resource pool allocated from the base station to a group including the plurality of user terminals;
- and
- transmitting the feedback information to the base station using the selected uplink radio resources.
