MOBILE STATION AND RADIO BASE STATION

摘要

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.

1. A mobile station comprising:
a transmission unit configured, when resources for a collision-type scheduling request signal to be shared with a different mobile station are set up, to transmit a collision-type scheduling request signal including an identifier of the mobile station by using the resources for a collision-type scheduling request signal, wherein when no resources for an uplink data signal are allocated in response to the collision-type scheduling request signal, the transmission unit is configured to retransmit the collision-type scheduling request signal by using the resources for a collision-type scheduling request signal.
