## Abstract

A method and apparatus for transmitting feedback information are provided. The method comprises: a terminal device receives first downlink data, the first downlink data being borne in a first time-domain resource unit in a first time-domain resource set, the first time-domain resource set comprising at least one time-domain resource unit; the terminal device determines transmitting feedback information for the first downlink data in a second time-domain resource unit according to a location of the first time-domain resource unit in the first time-domain resource set.

## Claims

### Claim 1

A method for transmitting feedback information, comprising:
receiving, by terminal equipment, first downlink data, wherein the first downlink data is born in a first time-domain resource unit in a first time-domain resource set, the first time-domain resource set comprises at least one time-domain resource unit;
determining, by the terminal equipment, transmitting feedback information for the first downlink data in a second time-domain resource unit according to a location of the first time-domain resource unit in the first time-domain resource set; and
transmitting, by the terminal equipment, L sets of feedback information in the second time-domain resource unit, wherein the L sets of feedback information comprise the feedback information for the first downlink data, each set of the L sets of feedback information comprises C-bit feedback information, LQ, Q is a number of time-domain resource units comprised in the first time-domain resource set, C is a maximum feedback information amount corresponding to downlink data born in a time-domain resource unit.

### Claim 2 (depends on 1)

The method according to claim 1, wherein QT, T is a positive integer, and a value of T is determined according to a system processing delay.

### Claim 3 (depends on 2)

The method according to claim 2, wherein first Q-T time-domain resource units in the first time-domain resource set comprise the first time-domain resource unit.

### Claim 4 (depends on 1)

The method according to claim 1, further comprising:
determining, by the terminal equipment, a bit position of the feedback information for the first downlink data in the L sets of feedback information according to the location of the first time-domain resource unit in the first time-domain resource set.

### Claim 5 (depends on 1)

The method for transmitting feedback information according to claim 1, wherein the terminal equipment determines transmitting feedback information for the first downlink data in the second time-domain resource unit according to the location of the first time-domain resource unit in the first time-domain resource set and a system processing delay.

### Claim 6

An apparatus for transmitting feedback information, comprising:
a transceiver,
a processor; and
a memory for storing instructions,
wherein the processor is configured to execute the instructions to:
control the transceiver to receive first downlink data, wherein the first downlink data is born in a first time-domain resource unit in a first time-domain resource set, the first time-domain resource set comprises at least one time-domain resource unit;
determine transmitting feedback information for the first downlink data in a second time-domain resource unit according to a location of the first time-domain resource unit in the first time-domain resource set; and
control the transceiver to transmit L sets of feedback information in the second time-domain resource unit, wherein the L sets of feedback information comprise the feedback information for the first downlink data, each set of the L sets of feedback information comprises C-bit feedback information, LQ is a number of time-domain resource units comprised in the first time-domain resource set, C is a maximum feedback information amount corresponding to downlink data born in a time-domain resource unit.

### Claim 7 (depends on 6)

The apparatus according to claim 6, wherein QT, T is a positive integer, and a value of T is determined according to a system processing delay.

### Claim 8 (depends on 7)

The apparatus according to claim 7, wherein first Q-T time-domain resource units in the first time-domain resource set comprise the first time-domain resource unit.

### Claim 9 (depends on 6)

The apparatus according to claim 6, wherein the processor is further configured to:
determine a bit position of the feedback information for the first downlink data in the L sets of feedback information according to the location of the first time-domain resource unit in the first time-domain resource set.

### Claim 10 (depends on 6)

The apparatus for transmitting feedback information according to claim 6, wherein the processor is configured to execute the instructions to determine transmitting feedback information for the first downlink data in the second time-domain resource unit according to the location of the first time-domain resource unit in the first time-domain resource set and a system processing delay.
