TECHNICAL FIELD The present disclosure relates to, but not limited to, the technical field of communication, in particular to an SRS transmission method, a terminal device and a storage medium. BACKGROUND With the development of communication technology, 5G communication is applied more and more widely. A terminal device adopts Multiple Input Multiple Output (MIMO) technology with multiple antennas, and the use of MIMO antennas improves the spatial multiplexing gain and greatly improves the transmission performance. A wireless performance parameter is an indication of transmission performance, and the wireless performance parameter of the terminal device usually depends on resources allocated by a base station. The terminal device sends a Sounding Reference Signal (SRS) to the base station, and the base station obtains a detection result of channel quality according to the SRS and allocates resources according to the detection result. Due to a large number of antennas and channels, the SRS is easily interfered by various factors in a transmission path, resulting in less resources allocated by the base station according to the SRS, which affects the transmission performance of the terminal device.
