Embodiments of this application disclose a time domain resource allocation method. The method may include: determining N pieces of candidate time domain resource information, where N is greater than or equal to 2; and receiving indication information, where the indication information is to be used to determine, from the N pieces of candidate time domain resource information, a time domain resource allocated to a data channel. For at least one of M frame structure parameters, a time domain resource indicated by at least one of the N pieces of candidate time domain resource information is different from a time domain resource used by at least one of the following signals and/or channels in LTE: a cell-specific reference signal (CRS), a physical downlink control channel (PDCCH), a multimedia broadcast single frequency network (MBSFN), a primary synchronization signal (PSS), a secondary synchronization signal (SSS), and/or a physical broadcast channel (PBCH).
