Abstract
A method includes: determining a Cyclic Shift (CS) parameter that implicitly indicates an orthogonality allocation rule and orthogonality-related information, by determining a multiple access state of a User Equipment (UE), and transmitting the determined CS parameter to the UE, wherein the orthogonality-related information includes an Orthogonal Cover Code indicated by the CS parameter, the orthogonality allocation rule is determined as a uniform scheme or a non-uniform scheme according to the CS parameter, determining the CS parameter by which the non-uniform scheme is applied if the UE is in a Single User Multiple Input Multiple Output state, and determining the CS parameter by which the uniform scheme is applied if the UE is in a Multiple User Multiple Input Multiple Output state.
