Wireless communication systems and methods using reference signals

摘要

A method used in a wireless communication apparatus based on reference signals is provided. The method may include obtaining a plurality of pilot rules and obtaining radio channel information of a radio channel between the wireless communication apparatus and another wireless communication apparatus. The wireless communication apparatus may be in an area including at least one cell and using one or more data streams. Further, the method may include selecting applicable pilot rules from the plurality of pilot rules based on the radio channel information, creating at least one pilot structure to be used in the radio channel; and using the created at least one pilot structure to transmit data over the radio channel.
