Claim 10:
11. A non-transitory computer-readable storage medium having stored therein computer instructions that, when executed by a processor, implements a method for transmitting a reference signal, applied to a vehicle terminal, comprising:
acquiring a current driving speed;
determining a corresponding reference signal transmission density according to a speed level to which the current driving speed belongs;
sending a reference signal to a connected vehicle terminal at an opposite end according to the corresponding reference signal transmission density, and sending level identification information of the speed level to the connected vehicle terminal at the opposite end; wherein the reference signal and the level identification information are transmitted in a same information block;
receiving feedback information sent by the connected vehicle terminal at the opposite end; and
in response to the feedback information meeting a preset increase condition, increasing the speed level to which the current driving speed belongs;
wherein the feedback information comprises a feedback signal for the reference signal, and the preset increase condition comprises: the feedback signal indicating reception failure, and a number of consecutive failures reaching a preset failure number threshold.
