HARQ number determination method, network device, and terminal

A method for determining a HARQ identifier, the method comprising:

• determining, by a terminal on a non-dynamic resource, a HARQ identifier of a transport block (TB) based on at least one of a first time domain resource sequence number of a current TB, a number of HARQ processes, a time domain period of a non-dynamic resource, or a HARQ identifier offset;
• and
• sending, by the terminal, the TB according to the HARQ ID to a network device;
• wherein the HARQ ID satisfies a formula:
• HARQ Process ID=[floor((t_temp−current_n)/T)]modulo B;
• or
• HARQ Process ID=[floor((t_temp−current_n)/T)]modulo B+Hoffset;
• wherein the HARQ Process ID is the HARQ ID of the TB, t represents a time domain resource sequence number of the TB, T represents a time domain resource period of the non-dynamic resource, (t_temp−current_n) is the first time domain resource sequence number, t_temp is a parameter obtained by converting t based on a specific time unit, current_n represents a number of transmission times of the TB, B represents the number of HARQ processes corresponding to the TB, floor represents rounding down, modulo represents modulo operation, and Hoffset represents a HARQ ID offset.

A terminal, comprising:

• a communication interface;
• a memory configured to store computer-executable instructions;
• and
• one or more processors in communication with communication interface and the memory and configured to execute the computer-executable instructions to at least:
• determine a HARQ identifier of a transport block (TB) based on at least one of a first time domain resource sequence number of a current TB, a number of HARQ processes, a time domain period of a non-dynamic resource, or a HARQ identifier offset;
• and
• send, by the communication interface, the TB according to the HARQ ID to a network device;
• wherein
• the HARQ ID satisfies a formula:
• HARQ Process ID=[floor((t_temp−current_n)/T)]modulo B;
• or
• HARQ Process ID=[floor((t_temp−current_n)/T)]modulo B+Hoffset;
• wherein the HARQ Process ID is the HARQ ID of the TB, t represents a time domain resource sequence number of the TB, T represents a time domain resource period of the non-dynamic resource, (t_temp−current_n) is the first time domain resource sequence number, t_temp is a parameter obtained by converting t based on a specific time unit, current_n represents a number of transmission times of the TB, B represents the number of HARQ processes corresponding to the TB, floor represents rounding down, modulo represents modulo operation, and Hoffset represents a HARQ ID offset.
