1. A feedback information transmission method, being applied in a first terminal and comprising:
selecting a basic sequence according to an information item of sidelink communication;
generating feedback information of the sidelink communication according to the basic sequence; and
transmitting the feedback information to a second terminal;
wherein selecting the basic sequence according to the information item of the sidelink communication comprises:
generating a first identity according to the information item of the sidelink communication;
performing the first identity mod n to obtain a group number of the basic sequence, the n being a group number of candidate basic sequences; and
selecting the basic sequence according to the group number; and
wherein selecting the basic sequence according to the group number comprises:
selecting a first basic sequence when the basic sequence corresponding to the group number comprises the first basic sequence;
selecting the first basic sequence, or selecting a second basic sequence when the basic sequence corresponding to the group number comprises the first basic sequence and the second basic sequence; or
generating a pseudo-random number when the basic sequence corresponding to the group number comprises a first basic sequence and a second basic sequence; and selecting the first basic sequence or the second basic sequence according to the pseudo-random number.
