Abstract: A Method of scrambling reference signals, device and user equipment using the method are provided. In the method, a plurality of layers of reference signals assigned on predetermined radio resource of a plurality of layers of resource blocks with the same time and frequency resources are scrambled, the method comprising: an orthogonalizing step of multiplying each layer of reference signal selectively by one of a plurality of orthogonal cover codes (OCCs) with the same length wherein the OCC multiplied to a first layer of reference signal can be configured as different from those multiplied to other layers of reference signals; and a scrambling step of multiplying all of symbols obtained from the OCC multiplied to each of the other layers of reference signals by a symbol-common scrambling sequence wherein the symbol-common scrambling sequences can be different from each other for reference signals multiplied by the same OCC.

Abstract: A communication apparatus includes a receiver and a transmitter. The receiver, in operation, receives from a neighboring cell a reference signal mapped to at least one first resource element. No signal is received from a serving cell on the at least one first resource element. The transmitter, in operation, transmits to a base station measurement information obtained based on the reference signal.
