HARQ feedback method and apparatus

A hybrid automatic repeat request (HARQ) feedback method, applicable to a base station that allocates, to a terminal, multiple available scheduling resources configured to provide Early Data Transmission (EDT) service, the method comprising:

• performing blind detection on EDT data transmitted to the base station by the terminal on the multiple available scheduling resources;
• determining a HARQ feedback time point for the blind detection according to a preset rule that a HARQ feedback is made only when a blind detection result is successful demodulation, comprising:
• for each available scheduling resource, determining a respective uplink (UL) transmission ending time point based on a Transmission Block Size (TBS) and a UL transmission repetition count in the available scheduling resource;
• and
• for each UL transmission ending time point, determining a respective HARQ feedback time point, wherein the determined HARQ feedback time point is at a specified position after the UL transmission ending time point;
• and
• sending HARQ information about the blind detection to the terminal at the HARQ feedback time point.

A base station that allocates to, a terminal, multiple available scheduling resources configured to provide Early Data Transmission (EDT) service, the base station comprising:

• a processor;
• and
• memory configured to store instructions executable by a processor,
• wherein the processor is configured to:
• perform blind detection on EDT data transmitted to the base station by the terminal on the multiple available scheduling resources;
• determine a hybrid automatic repeat request (HARQ) feedback time point for the blind detection according to a preset rule that a HARQ feedback is made based on a maximum uplink transmission repetition count, comprising:
• for each available scheduling resource, determining a respective uplink (UL) transmission ending time point based on a Transmission Block Size (TBS) and a UL transmission repetition count in the available scheduling resource;
• determining the maximum UL transmission repetition count according to UL transmission repetition counts in the multiple available scheduling resources;
• determining an UL transmission ending time point corresponding to the maximum UL transmission repetition count according to UL transmission ending time points corresponding to the multiple available scheduling resources;
• and
• determining the HARQ feedback time point based on the UL transmission ending time point corresponding to the maximum UL transmission repetition count, wherein the determined HARQ feedback time point is at a specified position after the UL transmission ending time point corresponding to the maximum UL transmission repetition count;
• and
• send HARQ information about the blind detection to the terminal at the HARQ feedback time point.
