Abstract
A method, a terminal, and a base station for asynchronous uplink transmission are provided, to reduce an uplink data transmission latency and signaling overheads when a terminal and a base station are in out-of-synchronization state. The method includes: obtaining asynchronous transmission parameter information that is the same as that of a base station, where asynchronous transmission parameter information includes physical resource information, modulation and coding scheme information, and physical resource frame format information, and the physical resource frame format information includes length information of a physical resource frame; determining a length of an asynchronous transmission frame according to the physical resource frame format information; and sending first uplink information to the base station according to the asynchronous transmission parameter information by using the asynchronous transmission frame.
