    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.

    Abstract: Methods and devices for using an unlicensed carrier resource are provided. In a method for using an unlicensed carrier resource, an eNode B (eNB) receives indication information reported by a User Equipment (UE), where the indication information is used for indicating that a local Secondary Cell (Scell) of the UE is idle; upon a trigger of the indication information, the eNB detects whether a local Scell of the eNB is idle or not; and the eNB judges, according to a detection result, whether or not to use an unlicensed carrier resource which has been occupied by the UE.
