MOBILE STATION |
| 摘要 |
An object is to increase opportunities for starting “Inter-band CA”. A mobile station UE of the present invention includes a transmission unit 14 configured to postpone transmission of a random access preamble in a cell #2 when the mobile station UE in a “RRC_Connected state” in a cell #1 detects a start trigger of a random access procedure in the cell #2, and determines that an uplink signal is being transmitted in the cell #1. The transmission unit 14 performs the postponed transmission of the random access preamble upon completing the transmission of the uplink signal in the cell #1. |

1. A mobile station comprising a transmission unit configured to postpone transmission of a random access preamble in a second cell when the mobile station in a connected state in a first cell detects a start trigger of a random access procedure in the second cell, and determines that an uplink signal is being transmitted in the first cell, wherein
the transmission unit performs the postponed transmission of the random access preamble upon completing the transmission of the uplink signal in the first cell. |
