1. An information transmission method applied to a first terminal device, the method comprising:
receiving sidelink data transmitted by a second terminal device, wherein the sidelink data carries indication information, and the indication information is used to determine a target transmitting power of feedback information corresponding to the sidelink data;
determining the target transmitting power of the feedback information according to the indication information; and
transmitting the feedback information to the second terminal device with the target transmitting power;
wherein the indication information comprises first information, and the first information is used to determine a transmitting power of the second terminal device;
wherein the method further comprises:
receiving configuration information of a resource pool transmitted by a network device, wherein the configuration information of the resource pool comprises second information, and the second information is used to determine a target receiving power of the second terminal device;
wherein the second information comprises a difference between the target receiving power of the second terminal device and a second power, wherein the second power is in any one of the following forms: a maximum transmitting power of the second terminal device, a pre-configured power value and a power value determined by the second terminal device;
wherein the determining the target transmitting power of the feedback information according to the indication information comprises:
acquiring multiple sidelink reference signal receiving powers corresponding to the sidelink data;
performing filtering processing on the multiple sidelink reference signal receiving powers to obtain a filtered sidelink reference signal receiving power;
determining a transmitting power of the second terminal device according to the first information;
determining a path loss of the sidelink between the second terminal device and the first terminal device according to the filtered sidelink reference signal receiving power and the transmitting power of the second device; and
determining the target transmitting power of the feedback information according to the path loss of the sidelink and the second information.
