A method for data storage, a terminal equipment and a base station are provided. In the method, a terminal equipment receives configuration signaling sent by a base station, the configuration signaling being used to enable the terminal equipment to determine a first parameter, and a number of Transport Blocks (TBs) stored in a buffer by the terminal equipment is equal to the first parameter when a number of TBs, which are failed to be decoded, of the terminal equipment is equal to the first parameter.
