Title:
A mobile station and a base transceiver station
Document Type and Number:
Japanese Patent JP6227968
Kind Code:
B2
Abstract:
The present invention prevents the occurrence of interference in an uplink in a case of adding a "UL Scell" while CA is being performed using a Pcell and a "DL Scell. " A mobile station UE according to the present invention is configured such that, in a case where the mobile station UE adds a "UL Scell" while performing CA by using a Pcell and a "DL Scell", the mobile station UE suspends signal transmission using the "UL Scell" for a predetermined length of time even if the "DL Scell is in an active state.
