Abstract
In order to appropriately set CA, a mobile communication method according to the present invention includes the steps where: a mobile station UE notifies a radio base station eNB of a “CA band combination” that is supported by the mobile station UE among “CA band combinations”; and the radio base station eNB determines whether or not to set carrier aggregation for the mobile station UE on the basis of whether or not “NS” corresponding to a band used in carrier aggregation is included in the “NS” specified by the received “CA band combination”.
Claims2
A mobile communication method comprising the steps of:
- causing a mobile station to notify a radio base station of a piece of carrier aggregation band combination information that is supported by the mobile station among pieces of carrier aggregation band combination information each of which specifies network signaling values corresponding to a band usable in carrier aggregation;
- and
- causing the radio base station to determine whether or not to set carrier aggregation for the mobile station on the basis of whether or not network signaling values corresponding to a band used in carrier aggregation are included in the network signaling values specified by the received piece of combination information.
A radio base station comprising:
- a receiver unit configured to acquire, from a mobile station, a piece of carrier aggregation band combination information that is supported by the mobile station among pieces of carrier aggregation band combination information each of which specifies network signaling values corresponding to a band usable in carrier aggregation;
- and
- a control unit configured to determine whether or not to set carrier aggregation for the mobile station on the basis of whether or not network signaling values corresponding to a band being used in carrier aggregation are included in the network signaling values specified by the received piece of combination information.
