Physical downlink shared channel transmission method and system |
摘要 |
Disclosed is a physical downlink shared channel transmission method, and the method includes: a network side determines transmission parameters of a Physical Downlink Shared Channel (PDSCH) according to a relevant transmission mode of a DM-RS and/or relevant information of a scheduled UE, wherein the transmission parameters include one or more of: a resource mapping approach of the PDSCH, a downlink DM-RS antenna port in use, and a Scrambling Code Identity (SCID) and a scrambling code initialized value X desired when a downlink DM-RS port sequence is initialized; and the network side transmits data according to the determined antenna parameters of the PDSCH. Further disclosed is a physical downlink shared channel transmission system. The disclosure can implement selection of DM-RS antenna ports and use multiple DM-RS antenna ports to improve transmission reliability, eliminate interference, increase MU-MIMO multiplexing capacity and improve frequency selective gain. |

1. A physical downlink shared channel transmission method, comprising:
determining, by a network side, transmission parameters of a Physical Downlink Shared Channel (PDSCH), according to a relevant transmission mode of a DM-RS and/or relevant information of a scheduled UE, wherein the transmission parameters include one or more of: a resource mapping approach of the PDSCH, a downlink DM-RS antenna port in use, and a Scrambling Code Identity (SCID) and a scrambling code initialized value X desired when a downlink DM-RS port sequence is initialized; and transmitting data, by the network side, according to the determined transmission parameters of the PDSCH. |
