Sidelink data transmission method, device and storage medium

A terminal device, comprising:

• a processor, a memory and an interface communicating with a network device or other terminal devices;
• the memory stores computer execution instructions;
• the processor when executing the computer execution instruction, being configured to:
• determine N slots of a first sidelink communication system according to a subcarrier spacing of the first sidelink communication system, wherein N is greater than or equal to 2, a time domain length of the N slots of the first sidelink communication system is as same as a time domain length of one subframe of a second sidelink communication system;
• and
• the processor controls the interface to perform at least one of following operations:
• transmit first sidelink data of the first sidelink communication system and second sidelink data of the second sidelink communication system within a time duration corresponding to a time domain symbol that is used to transmit the second sidelink data of the second sidelink of the second sidelink communication system within a subframe of the second sidelink;
• or, not transmit the first sidelink data and the second sidelink data within a time duration corresponding to a time domain symbol that is not used to transmit the second sidelink data of the second sidelink communication system within the subframe.
