1. A feedback information transmission method, performed by a terminal device, comprising:
receiving at least one piece of transmission information transmitted on at least one physical sidelink channel;
determining power information corresponding to each of at least one piece of feedback information that corresponds to the at least one piece of transmission information; and
transmitting corresponding feedback information on at least one physical sidelink feedback channel resource based on the power information corresponding to each piece of feedback information;
wherein before the determining power information corresponding to each of at least one piece of feedback information that corresponds to the at least one piece of transmission information, the method further comprises:
determining feedback information for which transmission needs to be dropped;
wherein the determining feedback information for which transmission needs to be dropped comprises:
determining, based on fourth attribute information of the transmission information, the feedback information for which transmission needs to be dropped, wherein the fourth attribute information comprises
a priority;
wherein the determining power information corresponding to each of at least one piece of feedback information that corresponds to the at least one piece of transmission information comprises:
determining power information corresponding to each piece of feedback information for which transmission has not been dropped;
wherein the determining power information corresponding to each piece of feedback information for which transmission has not been dropped comprises:
determining that the power information corresponding to each piece of feedback information for which transmission has not been dropped is preset power information; or
determining that the power information corresponding to each piece of feedback information for which transmission has not been dropped is an arithmetic mean of total power information divided by a quantity of feedback information.
