Document Type and Number:
Japanese Patent JP5793184
Kind Code:
B2
Abstract:
A transmission device includes reference signal generator (204) generates a transmission instruction for DMRS or SRS produced by base station (100), and an RS that corresponds to a transmission instruction in the DMRS and SRS on the basis of identification information of an RS pattern used in the DMRS and SRS and set in base station (100). Transmission signal formation unit (207) maps the generated RS to a time frequency resource. The RS pattern of the DMRS and the RS pattern of the SRS have a relationship in which the RS pattern of the SRS is obtained by adding the length of a CS series/4 to the cyclic shift amount, which is an element of the CS series pattern, in the RS pattern of the DMRS, and inverting the identification information of a first Walsh series or a second Walsh series, which are constituent elements of an OCC pattern.
