Abstract

The invention provides a vehicle-to-vehicle (V2V) communication resource allocation method based on a depth deterministic policy gradient (DDPG) algorithm, wherein the V2V communication accesses a 5G network by using a network slicing technology, an optimal V2V user channel allocation and transmitting power joint optimization strategy is obtained by using a deep reinforcement learning optimization strategy, V2V users select proper transmitting power and channels so as to reduce the mutual interference between the V2V links; the total system throughput of the V2V links is maximized under the condition that the link delay constraint is met. According to the method, the problem of joint optimization of V2V user channel allocation and power selection can be effectively solved by using the DDPG algorithm, and the performance is stable in optimization of a series of continuous action spaces.
