摘要： 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).

摘要： A method and an apparatus for determining an RBG size are provided. In the method, a network device or a terminal determines an RBG size set, where the RBG size set may include one or more possible RBG sizes; and determines a first RBG size included in the RBG size set. The network device allocates a resource to the terminal by using the determined first RBG size. The terminal determines, based on the determined first RBG size, the resource allocated by the network device to the terminal.
