Transmission method and apparatus for feedback information of uplink transmission

A method for transmitting feedback information of uplink transmission, the method comprising:

• scheduling, by a base station, a terminal to transmit a Physical Uplink Shared Channel (PUSCH) in a special subframe m, wherein m is an integer;
• detecting, by the base station, a PUSCH transmitted by the terminal in the special subframe m;
• and
• transmitting, by the base station, a downlink control channel with an uplink Downlink Control Information (DCI) format to the terminal in a subframe comprising a downlink transmission resource subsequent to the special subframe m, or in a subframe m+k, wherein k is a positive integer, and the downlink control channel carries an indicating field for indicating whether to retransmit the PUSCH transmitted in the special subframe m.

A terminal, comprising a transceiver, and at least one processor connected with the transceiver, wherein:

• the processor is configured to read and execute program in a memory:
• to control the transceiver to transmit a PUSCH in a special subframe m, wherein m is an integer;
• to detect a downlink control channel with an uplink DCI format in a subframe comprising a downlink transmission resource subsequent to the special subframe m, or in a subframe m+k, wherein k is a positive integer;
• and to decide whether to retransmit the PUSCH transmitted in the special subframe m, according to the downlink control channel;
• and
• the transceiver is configured to receive and transmit data under the control of the processor.

A base station, comprising a transceiver, and at least one processor connected with the transceiver, wherein:

• the processor is configured to read and execute program in a memory:
• to schedule a terminal through the transceiver to transmit a Physical Uplink Shared Channel (PUSCH) in a special subframe m, wherein m is an integer;
• to detect a PUSCH transmitted by the terminal in the special subframe m;
• and to control the transceiver to transmit a downlink control channel with an uplink DCI format to the terminal in a subframe comprising a downlink transmission resource subsequent to the special subframe m, or in a subframe m+k, wherein k is a positive integer, and the downlink control channel carries an indicating field for indicating whether to retransmit the PUSCH transmitted in the special subframe m;
• and
• the transceiver is configured to receive and transmit data under the control of the processor.
