Abstract
Official abstract text for this publication.
In CA performed using three or more frequency bands, whether or not a mobile station UE is capable of performing an inter-frequency measurement without a gap is properly determined. The mobile station UE according to the invention includes a transmission unit 11 configured to transmit “UE Capability” indicating a capability of the mobile station UE to a radio base station eNB. The transmission unit 11 is configured to notify frequency bands in which the mobile station UE is capable of performing an inter-frequency measurement without a gap for each “CA band combination” as the “UE Capability”.
First claim
Opening claim text (preview).
The invention claimed is: 1. A radio base station, comprising: a processor that controls carrier aggregation of a mobile station; and a receiver that receives an information element as capability information indicating a capability of the mobile station from the mobile station, the information element indicating whether or not the mobile station is capable of performing an inter-frequency measurement without a gap for each combination of two frequency bands, wherein when the information element indicates that an inter-frequency measurement is performable without a gap in all combinations of two frequency bands among three or more frequency bands, the processor determines that the mobile station is capable of performing an inter-frequency measurement without a gap in carrier aggregation performed using the three or more frequency bands, and the three or more frequency bands include an 800 MHz band, a 1.5 GHz band and a 2 GHz band. 2. A radio base station, comprising: a processor that controls carrier aggregation of a mobile station; and a receiver that receives an information element as capability information of the mobile station from the mobile station, the information element indicating whether or not the mobile station is capable of performing an inter-frequency measurement without a gap for each combination of two frequency bands, wherein when the information element indicates that the mobile station is capable of performing an inter-frequency measurement without a gap in all combinations of a frequency band including a primary component carrier and a frequency band including a secondary component carrier among three or more frequency bands, the processor determines that the mobile station is capable of performing an inter-frequency measurement without a gap in carrier aggregation performed using the three or more frequency bands, and the three or more frequency bands include an 800 MHz band, a 1.5 GHz band and a 2 GHz band.
