Abstract:
1. A method of an eNodeB apparatus including a processor for transmitting a Cyclic Shift (CS) parameter, the method comprising: determining, with a processor, the CS parameter which 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 comprises an Orthogonal Cover Code (OCC) 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 an SU-MIMO (Single User Multiple Input Multiple Output) state, determining the CS parameter by which the uniform scheme is applied if the UE is in an MU-MIMO (Multiple User Multiple Input Multiple Output) state.
