Mapping method and system for demodulation reference signal |
| abstract |
A mapping method and system for Demodulation Reference Signal are provided in the present invention. Wherein the method includes the following steps: on each Orthogonal Frequency Division Multiplexing (OFDM) symbol mapped by Demodulation Reference Signal (DMRS), different orthogonal mask mapping modes are equably distributed to different DMRS resource units of the OFDM symbol; the orthogonal mask mapping of each layer in a physical resource block guarantees orthogonality in the time domain, simultaneously in the frequency domain of said physical resource block, the orthogonal mask mapping of each layer at least guarantees that each current DMRS resource unit forms orthogonality relation with one or more resource units of the front or back consecutive resource units bearing DMRS. Using the method and system of the present invention, when rank >2, both the aspect of avoiding imbalance of transmission power and the aspect of guaranteeing orthogonality in time domain and frequency domain can be considered. |
