To provide a mobile station apparatus, a base station apparatus, a method and an integrated circuit which are capable of dissolving complexity of setting by the base station apparatus and performing efficient scheduling by improving the orthogonality of resources of a reference signal for every antenna. A mobile station apparatus which transmits a sounding reference signal to a base station apparatus using a plurality of antenna ports, wherein based on one value set specifically to a mobile station apparatus by a parameter notified of by a higher layer from the base station apparatus, a cyclic shift applied to a sounding reference signal corresponding to the plurality of antenna ports is determined. |
