Communication Method and Apparatus

A communication apparatus, comprising:

• a memory configured to store instructions;
• and
• one or more processors coupled to the memory and configured to execute the instructions to cause the communication apparatus to
• obtain first information through error correction encoding;
• divide the first information into M segments, wherein M is an integer greater than 1;
• determine M pieces of indication information that are in a one-to-one correspondence with the M segments and that indicate M reference signals corresponding to a scheduling-free resource;
• and
• send the M reference signals on the scheduling-free resource based on the M pieces of indication information.

A communication apparatus, comprising:

• a memory configured to store instructions;
• and
• one or more processors coupled to the memory and configured to execute the instructions to cause the communication apparatus to
• receive reference signals on a scheduling-free resource;
• determine first information indicating the reference signals;
• perform error correction decoding on the first information to obtain second information;
• divide the second information into M segments, wherein the M segments are in a one-to-one correspondence with M pieces of indication information, wherein the M pieces of indication information indicate that the reference signals are M reference signals, and wherein M is an integer greater than 1;
• and
• decode scheduling-free transmission using the second information.
