Abstract:
A radio terminal receives multicast data belonging to an MBMS service from a base station. The radio terminal includes a receiver configured to receive configuration information indicating one or more common resource pools shared by a plurality of radio terminals to transmit feedback information corresponding to the multicast data to the base station, the configuration information including information indicating a correspondence relationship between an attribute of the feedback information and a common resource pool and/or a signal sequence; a controller configured to select a specific common resource pool used for transmission of the feedback information and/or a specific signal sequence used for transmission of the feedback information, based on the attribute of the feedback information to be transmitted to the base station and the correspondence relationship; and a transmitter configured to transmit the feedback information to the base station using the specific common resource pool and/or the specific signal sequence.
