Abstract: Disclosed is a sounding reference signal (SRS) transmission method. The method comprises: determining a resource on an unlicensed carrier for transmitting an SRS; and transmitting the SRS according to the determined resource. The invention solves a problem in the prior art in which transmitting an SRS on an unlicensed carrier is less feasible, thereby increasing feasibility of transmitting an SRS on an unlicensed carrier. Also disclosed are an SRS reception method, an apparatus, a system, and a storage medium.

Abstract: A method and apparatus for sending and receiving uplink data, a terminal, and a base station are provided. The method comprises: determining, according to a self-defined instruction message or an instruction message received from a base station, a start symbol position or the start symbol position and an end symbol position for transmitting a subframe on a physical uplink shared channel (PUSCH) on an unlicensed carrier; and sending uplink data according to the start symbol position or according to the start symbol position and the end symbol position. By means of the embodiments of the present invention, the problem of failing to determine the time point of transmitting uplink data on an unlicensed carrier by a terminal is resolved, thereby achieving the effect of determining the time point of transmitting the uplink data on the unlicensed carrier by the terminal, and providing the effect of improving the data transmission efficiency.
