Response feedback method and apparatus, and terminal

A terminal, comprising a processor and a memory, wherein the memory stores a program or instructions capable of running on the processor, wherein the program or the instructions, when executed by the processor, cause the terminal to perform:

• determining a feedback mode and/or feedback resource for response feedback based on first information in a case that the terminal is scheduled to feed back hybrid automatic repeat request (HARQ) information of N downlink transmissions in one time unit, wherein N is a positive integer;
• the first information comprises at least one of the following:
• the number N of downlink transmissions, the number of group radio network temporary identities, or whether a network-side device has configured a first parameter;
• the first parameter is used to indicate a feedback mode for response feedback and/or a mode for feedback resource selection;
• the feedback mode comprises a first feedback mode and a second feedback mode, wherein the first feedback mode is:
• a terminal feeds back an acknowledge response (ACK) in a case that the terminal successfully decodes a physical downlink shared channel and/or physical downlink control channel;
• and a terminal feeds back a negative acknowledge response (NACK) in a case that the terminal fails to successfully decode a physical downlink shared channel and/or physical downlink control channel;
• and
• the second feedback mode is:
• a terminal feeds back a negative acknowledge response only in a case that the terminal fails to successfully decode a physical downlink shared channel and/or physical downlink control channel.

A non-transitory readable storage medium, wherein the non-transitory readable storage medium stores a program or instructions, wherein the program or instructions, when executed by a processor of a terminal, cause the terminal to perform:

• determining a feedback mode and/or feedback resource for response feedback based on first information in a case that the terminal is scheduled to feed back hybrid automatic repeat request (HARQ) information of N downlink transmissions in one time unit, wherein N is a positive integer;
• the first information comprises at least one of the following:
• the number N of downlink transmissions, the number of group radio network temporary identities, or whether a network-side device has configured a first parameter;
• the first parameter is used to indicate a feedback mode for response feedback and/or a mode for feedback resource selection;
• the feedback mode comprises a first feedback mode and a second feedback mode, wherein the first feedback mode is:
• a terminal feeds back an acknowledge response (ACK) in a case that the terminal successfully decodes a physical downlink shared channel and/or physical downlink control channel;
• and a terminal feeds back a negative acknowledge response (NACK) in a case that the terminal fails to successfully decode a physical downlink shared channel and/or physical downlink control channel;
• and
• the second feedback mode is:
• a terminal feeds back a negative acknowledge response only in a case that the terminal fails to successfully decode a physical downlink shared channel and/or physical downlink control channel.
