MULTI-ANTENNA TRANSMITTING METHOD AND APPARATUS FOR SOUNDING REFERENCE SIGNAL (SRS)

摘要

The present invention discloses a multi-antenna transmitting method and apparatus for Sounding Reference Signal (SRS). In the scheme of the present invention, in the case of using precoding to transmit uplink SRS, UE can provide orthogonal resources for different precoding matrixes through the modes of CDM, or TDM, or FDM, or the mutual combination of the three above; in the case of not using precoding to transmit uplink SRS, UE can transmit SRS in orthogonal resources through the modes of CDM, or TDM, or FDM, or the mutual combination of the three above. The scheme of the present invention provides feasible implement solution for transmitting uplink SRS in multi-antenna condition.
