Wireless communication apparatus and reference signal generating method

摘要

Provided are a wireless communication apparatus and a reference signal generating method, wherein inter-cell interference is reduced inside and outside a CoMP set. A CoMP mode setting unit (101) sets whether the terminal (100) thereof is a CoMP terminal or a Non-CoMP terminal. When the terminal (100) is set as a Non-CoMP terminal, the hopping pattern calculating unit (104) calculates a ZC sequence number to be used as the transmission timing, from among all the ZC sequence numbers that can be used within the system. When the terminal (100) is set as a CoMP terminal, the hopping pattern calculating unit (104) calculates a ZC sequence number to be used as the transmission timing, by hopping the ZC sequence numbers to be used within the CoMP set. A ZC sequence generating unit (105) generates a ZC sequence to be used as an SRS, using the calculated ZC sequence number.

1. A radio communication apparatus comprising:
a hopping pattern calculation section configured to calculate a sequence number using a hopping pattern that defines a variation of sequence numbers over time, the hopping pattern being defined differently by whether a CoMP (Coordinated Multiple Point transmission and reception) mode or Non-CoMP mode is set, wherein, when the CoMP mode is set, a plurality of base stations or cells communicate with the radio communication apparatus in a coordinated manner between the plurality of base stations or cells; and a sequence generation section configured to generate a sequence used for a reference signal using the calculated sequence number.
