Mobile station apparatus, base station apparatus, method and integrated circuit

摘要

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.

主权项

1. A mobile station apparatus configured to communicate with a base station apparatus, the mobile station apparatus comprising:
a receiving unit configured to receive information for indicating a number of one or more antenna ports being used for transmission of one or more sounding reference signals; and a transmitting unit configured to determine a number of sequences being generated for the one or more sounding reference signals in accordance with the number of one or more antenna ports set based on the information in a case that the information is set.
