A method for realizing a semi-persistent scheduling, SPS, or SPS-like service, comprising: notifying a terminal of its SPS or SPS-like period, so that the terminal sends, by adopting a multiple input multiple output, MIMO, transmission mode with a closed loop rank 1, SPS service or SPS-like service data according to the period; dynamically notifying the terminal of a precoding matrix indicator, PMI, required for its SPS service or SPS-like service to support the transmission mode with the closed loop rank 1, so that the terminal uses a latest received PMI when sending the SPS service or SPS-like service data; and receiving, based on the transmission mode with the closed loop rank 1, the SPS-service or SPS-like service data sent by the terminal, wherein the SPS-like service is a non-SPS service that is activated and released through physical downlink control channel, PDCCH, signaling or that transmits information on a predefined frequency resource at fixed periods through higher layer signaling configuration; wherein, the method further comprises: grouping, in advance, terminals having SPS service or SPS-like service, allocating one group identifier to each group, allocating one intra-group identifier to the terminal, and notifying the group identifier and intra-group identifier of the terminal to the terminal, so that the terminal detects a physical downlink control channel, PDCCH, downlink control information, DCI, format according to its own group identifier and obtains the corresponding PMI according to its own intra-group identifier; and the dynamically notifying the terminal of a PMI required for its SPS service or SPS-like service to support the transmission mode with the closed loop rank 1 comprises: using the group identifier of each group to mask the cyclical redundancy check, CRC, of a PDCCH, and using the PDCCH to multicast, to terminals in each group, PMIs required for their SPS services or SPS-like services to support the transmission mode with the closed loop rank 1. notifying a terminal of its SPS or SPS-like period, so that the terminal sends, by adopting a multiple input multiple output, MIMO, transmission mode with a closed loop rank 1, SPS service or SPS-like service data according to the period;
