Abstract:
Apparatus and method for communication are provided. The apparatus includes one or more antenna ports; and a processor configured to share a cyclic shift space of reference signals of user equipment utilizing single user multiple input multiple output transmission by applying a cyclic shift increment value between reference signals of different antenna ports or spatial layers of the user equipment transmission.
