摘要： A method and system of assigning reference signals to antennas and nodes in a wireless communication system, the wireless communication system comprising N number of transmitting nodes, wherein N is an integer N≧1, is disclosed. The transmitting nodes are transmitting reference signals in a first slot and a second slot within sub-frames, over the same bandwidth. Each transmitting node has at least one transmit antenna, wherein different nodes can have different number of transmit antennas. The reference signals are of two different types, a first type of reference signals used for demodulation, and a second type of reference signals used for measurements. According to the method, reference signals of the first type is assigned to a number of transmitting nodes with at least one transmit antenna in the first and second slot in a predefined bandwidth; and reference signals of the second type is assigned to at least one transmitting node with at least transmit antennas in at least one of the first and second slot in a predefined bandwidth.
