Abstract: 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).

Abstract: This application discloses an indoor-outdoor determining-based uplink transmission method and apparatus. A terminal device or a positioning device determines whether the terminal device is located indoors or outdoors. The terminal device or the positioning device sends a first message to an access network device, where the first message includes a first information element, and the first information element indicates whether the terminal device is located indoors or outdoors. The access network device determines an access parameter of the terminal device based on the first information element, where the access parameter includes an access frequency. According to the method disclosed in embodiments of this application, uplink transmission of the terminal device in a proper frequency band is implemented, and communication interference is reduced.

Abstract: A rate matching method including: determining a receiving capability of a receive end, where the receiving capability is used to indicate a maximum data processing volume of the receive end in a first transmission time, and/or the receiving capability is used to indicate a maximum data buffer volume of the receive end in a first transmission time; the first transmission time is used to transmit a first transport block to which a first code block belongs; determining NCB based on the receiving capability, where NCB represents a code block size used for rate matching; performing rate matching on the first code block based on NCB. The receive end can adjust, based on a processing capability and/or a buffer capability that are/is of the receive end in a period of time, the code block size used for rate de-matching, to avoid insufficiency in processing capability and/or buffer overflow at the receive end.
