Abstract
When an “always-on” method is applied, a situation of a shortage in resources for transmitting a SR is avoided while avoiding a delay in transmission of an uplink data signal or a drop in use efficiency of resources. A mobile station (UE) of the invention includes a transmission unit (23) configured, when resources for a collision-type SR to be shared with a different mobile station (UE) are set up, to transmit a collision-type SR including an identifier of the mobile station (UE) by using the resources for a collision-type SR. When no resources for an uplink data signal are allocated for the collision-type SR, the transmission unit (23) is configured to retransmit the collision-type SR by using the resources for a collision-type SR.
