Methods for scheduling transport blocks, and an apparatus for scheduling transport blocks. The method includes: determining transmission interval parameters, in which the transmission interval parameters are used to determine a mode of setting a transmission interval among transport blocks; scheduling the transport blocks on a physical downlink control channel (PDCCH) according to the transmission interval parameters, the transport blocks scheduled on the PDCCH including at least one of physical uplink shared channel (PUSCH) transport blocks and physical downlink shared channel (PDSCH) transport blocks.
