Feedback method for uplink channel, and apparatus

A base station, comprising:

• a processor, configured to determine whether a data packet to be sent by a terminal is a last data packet of the terminal;
• a receiver, configured to receive the data packet from the terminal;
• and
• a transmitter, configured to send a common message to the terminal after the receiver receives the data packet sent by the terminal, wherein the common message comprises feedback information, the feedback information being able to carry at least two indication bits for at least two terminals comprising the terminal, and the at least two indication bits comprise an indication bit that is used to indicate whether the base station correctly receives the data packet sent by the terminal, wherein
• the transmitter is further configured to send a first scheduling command to the terminal after the receiver receives the data packet sent by the terminal, wherein the first scheduling command comprises an indication bit that is used to indicate whether the base station correctly receives the data packet sent by the terminal, and the first scheduling command is used to schedule the terminal to resend the data packet or send a next new data packet.

A terminal, comprising:

• a receiver, configured to receive a first scheduling command from a base station, wherein the first scheduling command comprises feedback resource indication information;
• and
• a processor, configured to:
• obtain feedback information from a common message after sending a date packet to determine whether the base station correctly receives the data packet in a case that the feedback resource indication information indicates obtaining the feedback information from the common message, wherein the feedback information in the common message being able to carry the at least two indication bits for at least two terminals comprising the terminal, and the at least two indication bits comprise an indication bit that is used to indicate whether the base station correctly receives the data packet sent by the terminal;
• and
• obtain feedback information from a second scheduling command after sending a data packet to determine whether the base station correctly receives the data packet in a case that the feedback resource indication information indicates obtaining the feedback information from the second scheduling command, wherein the feedback information in the second scheduling command comprises an indication bit that is used to indicate whether the base station correctly receives the data packet sent by the terminal, and the second scheduling command is used to schedule the terminal to resend the data packet or send a next new data packet.
