For example, the link policy (Link Policy) of some communication systems has been defined in the communication protocol. For example, in the Bluetooth specification, the connection status of the communication device is divided into active mode, sniff mode, hold (Hold) mode, sleep (Park) mode, etc. For breathing mode, the receiving device only receives in the pre-agreed time slots between the sending and receiving parties, but the way of receiving data based on fixed rules cannot adapt to changes in the communication environment. For the active mode , the receiving device needs to perform radio frequency reception in each receiving time slot, and the power consumption is still high

Abstract
The invention relates to the technical field of wireless communication, in particular to a method, a device and a wirelesscommunication device for predicting a receiving window of wireless communication. The wireless communication reception window prediction method has a training mode and a utilization mode. In the training mode, global information is obtained, and the global information includes the current state information and information on whether the receiving action taken in the current time slot is correct, Based on the global information, perform deep reinforcement learning training to obtain an optimal receiving strategy, and update the current receiving strategy with the optimal receiving strategy; in the utilization mode, obtain current state information, and according to the current state information, and Based on the current receiving strategy obtained by deep reinforcement learning training, a receiving control signal is generated to determine whether to perform a data receiving action in the current time slot; the current state information indicates that the current time slot is the number after the latest received data packet is completed Receive slot. The invention avoids redundant reception and reduces reception power consumption.
