    Abstract: 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.

    Abstract: Provided are methods for sending and receiving ACK/NACK information, a base station, and a terminal, wherein the method for sending ACK/NACK information includes that ACK/NACK information of a plurality of terminals is divided into X groups according to a preset indication parameter, wherein X is a positive integer greater than or equal to 1; joint coding is performed on ACK/NACK information corresponding to each group in the X groups, so as to obtain X first bit blocks; and the X first bit blocks are mapped to a predetermined ACK/NACK physical resource and sent. By means of the disclosure, reliable transmission of HARQ-ACK information of a terminal on an NCT is implemented, the reliability of transmission of UL data in a Low Cost terminal is improved, and problems such as a conflict of PHICH resource allocation and ICIC of a frequency domain in a small cell are solved.
