PROBLEM TO BE SOLVED: To provide a method and an apparatus for controlling demodulation reference signal allocation of a user device by utilizing a cyclic shift subset determined for demodulation reference signal multiplexing orders supported by the user device.SOLUTION: Within a cyclic shift subset, demodulation reference signal resources that cause the most significant interference to each other are identified, and cyclic shifts corresponding to the identified demodulation reference signal resources, are linked with orthogonal complementary multiplexing resources as possible as. If a plurality of cyclic shift subsets is determined for a demodulation reference signal multiplexing order, at least one cyclic shift subset is ignored for the demodulation reference signal multiplexing order.SELECTED DRAWING: None |
