METHODS OF TRANSMITTING COORDINATE MULTIPLE POINT DATA BASED ON ORTHOGONAL COVERING CODES

摘要

The present invention relates to a method for transmitting a cooperative multi-point data based on the orthogonal covering code. In one embodiment of the present invention, a method for transmitting downlink data from the base station in a multiple-input multiple-output system it is provided. The method comprising: A. determining a plurality of antenna groups of a plurality of antennas of the multi-point collaboration cells; And B. using different orthogonal covering code comprises the step of modulating the inter-cell cooperative multipoint downlink data symbols for each antenna group. Covering orthogonal codes has a length no greater than two times the number of antenna groups. In the methods of the present invention, the base station and the user equipment is different cooperative multipoint cells, different antenna groups, or to be able to distinguish signals from different cooperative multipoint cluster, different cooperative multipoint cells, different antenna groups, or interference between signals from different cooperative multipoint cluster reduces. ;
