3 . The method of claim 2 , wherein the first-type SL feedback channel is for carrying at least one of:

hybrid automatic repeat request-acknowledgement (HARQ-ACK) information, channel quality indicator (CQI) information, rank indicator (RI) information, pre-coding matrix indicator (PMI) information, beam information, reference signal index information, power adjustment information, or measurement information.

4 . The method of claim 1 , wherein the resource pool indication information of the transmission resource of the SL feedback channel comprises second SL feedback resource pool indication information, the second SL feedback resource pool indication information is used for determining a transmission resource of the second-type SL feedback channel, and the second-type SL feedback channel is associated with the first SL data.

5 . The method of claim 4 , wherein the second-type SL feedback channel comprises a first sequence, and SL feedback information corresponding to the first SL data is carried by the first sequence.

6 . The method of claim 1 , wherein the resource pool indication information of the transmission resource of the SL feedback channel comprises second indication information, and the second indication information is used for determining a number of transmission resources of the SL feedback channel, wherein the number of the transmission resources of the SL feedback channel is greater than or equal to one.

7 . The method of claim 1 , further comprising:

obtaining, by the first terminal device, fifth indication information; and

determining, according to the fifth indication information, to transmit the SL feedback information using the first-type SL feedback channel or the second-type SL feedback channel.

8 . The method of claim 1 , further comprising:

determining, by the first terminal device according to a number of bits of the SL feedback information, to transmit the SL feedback information using the first-type SL feedback channel or the second-type SL feedback channel.

9 . The method of claim 1 , further comprising:

determining, by the first terminal device according to a type of the SL feedback information, to transmit the SL feedback information using the first-type SL feedback channel or the second-type SL feedback channel.

10 . A method for configuring a sidelink (SL) feedback resource, comprising:

transmitting, by a first communication device to a first terminal device, resource pool configuration information, the resource pool configuration information comprising resource pool indication information of a transmission resource of a SL data channel and resource pool indication information of a transmission resource of a SL feedback channel;

wherein the SL data channel is for transmitting first SL data, and the SL feedback channel comprises a first-type SL feedback channel and a second-type SL feedback channel; and

wherein the resource pool indication information of the transmission resource of the SL feedback channel comprises third indication information, and the third indication information is used for determining a number of transmissions of the SL feedback channel, wherein the number of transmissions is greater than or equal to one.

11 .
