1. A communication apparatus comprising:
circuitry, which, in operation, generates a reference signal, the reference signal being based on a sequence that is initialized with a random seed count generated by
cinit=(└ns/2┘+1)·(2ID+1)·216+SCID,
the random seed being one of a first random seed and a second random seed, the first random seed being generated using ID specific to a cell, and the second random seed being generated using ID dedicated to a user equipment (UE),
wherein, ns is a slot number, SCID is 0 or 1, and the ID is determined based on the SCID; and
a transmitter, which, in operation, transmits the reference signal to the UE.
