Grant-Free Transmission Method, Terminal, and Network Device

A terminal, wherein the terminal comprises:

• a transmitter;
• a processor, and a non-transitory computer-readable storage medium storing a program to be executed by the processor, the program including instructions to:
• select a pilot sequence, a sending attribute parameter group from N sending attribute parameter groups, and a grant-free transmission resource block unit;
• map the pilot sequence to a corresponding location on the resource block unit based on a relationship between the selected sending attribute parameter group and a time-frequency location of a pilot;
• and
• map to-be-transmitted data to another location on the resource block unit, wherein N is a positive integer greater than 1;
• cause the transmitter to send the pilot and the data to a network device based on a sending attribute parameter in the selected sending attribute parameter group.

A chip, comprising:

• an input interface, configured to obtain grant-free transmission resource information;
• a processor, configured to perform:
• obtaining a pilot sequence and a grant-free transmission resource block unit;
• selecting a sending attribute parameter group from N sending attribute parameter groups;
• mapping the pilot sequence to a corresponding location on the resource block unit based on a relationship between the selected sending attribute parameter group and a time-frequency location of a pilot;
• and
• mapping to-be-transmitted data to another location on the resource block unit, wherein N is a positive integer greater than 1;
• and
• an output interface, configured to output the to-be-sent pilot and the to-be-sent data.
