A METHOD AND SYSTEM FOR ASSIGNING REFERENCE SIGNALS IN A MULTI-ANTENNA CONTEXT

摘要

A method and system of assigning reference signals to antennas and nodes in a 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 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. 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 are type 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.
