PESCH (physical downlink shared channel) transmission method, system and network side equipment

The invention discloses a PESCH (physical downlink shared channel) transmission method, a system and network side equipment. The method comprises the following steps that the network side equipment determines transmission parameters of the PDSCH according to information relevant to dispatched UE (user equipment), wherein the transmission parameters of the PDSCH include at least one parameter from the following parameters: the transmission mode of the PDSCH, reference signals corresponding to the PDSCH and the power ratio of data corresponding to the reference signals, and the information relevant to the dispatched UE includes at least one content from the following contents: the channel state information reported by the UE, the transmission mode of the UE, the version and support capability information of the UE, the located service cell type information of the PDSCH and the located sub frame type information of the PDSCH; the network side equipment carries out resource mapping and sending according to the transmission parameters of the PDSCH. According to the method, the system and the network side equipment, the problems that whether the lifting reminding is carried out or not on the indication and pilot frequency power of the used transmission mode during the PDSCH transmission of the fallback transmission operation and the like are solved, the PDSCH transmission reliability is improved, and the channel estimation performance of the receiving end is improved.
