The invention relates to a distributed computing unloading method and device based on deep reinforcement learning. The method comprises the steps that a calculation unloading framework is set, a communication model and a calculation model are established according to the calculation unloading framework, the communication model is used for calculating the signal-to-noise-interference ratio of terminal equipment, the calculation model is used for conducting local calculation and edge calculation on the terminal equipment, and the terminal equipment is calculated based on the calculation unloading framework, the communication model and the calculation model. And modeling a calculation unloading problem into a Markov decision process, and carrying out optimization iteration solution on the Markov decision process by utilizing a depth deterministic strategy gradient algorithm of the double-Critic network to obtain an unloading decision. Due to the fact that the depth deterministic strategy gradient algorithm of the double Critic networks is used for conducting optimization iteration solution, the double Critic networks are respectively fitted, the complexity of fitting of a single Critic network is reduced, the convergence speed of the Critic networks is improved, and the overall convergence speed of the model is greatly improved.

A user pairing method is provided. The method includes the following steps: selecting a first uplink user device among the uplink set; selecting a first downlink user device among the downlink set; determining whether the first uplink channel gain corresponding to the first uplink user device is greater than a second uplink channel gain corresponding to the first downlink user device, to generate a first determination result; determining whether a first signal to noise plus interference ratio (SINR) perceived at the first downlink user device is greater than a first SINR threshold, to generate a second determination result; forming the first uplink user device and the first downlink user device as a first user pair in a full duplexing (FD) mode when the first determination result and the second first determination result are positive.
