step 101, set one UE of a plurality of UEs (User Equipment) built in the urrllc device as a master UE, and set the remaining UEs as slave UEs.
In an embodiment, the uRLLC device may be a device supporting 5G uRLLC services, and may be an unmanned aerial vehicle, an unmanned vehicle, or the like. Two or more UEs are built in one urrllc device, and the UE may be various devices, apparatuses, and the like, and is used for communicating with the outside. One UE is selected from the multiple UEs as a master UE, the channel quality of the master UE is better, data transmission is more stable, and the other UEs are slave UEs.
Step 102, configuring a conventional communication power parameter template for the master UE and the slave UE, so that the master UE and the slave UE use the conventional communication power parameter template for data transmission.
In one embodiment, two or more sets of communication power templates (with different DRX parameters) are stored in the urrllc device, wherein one set is the best-performing communication power template (regular communication power parameter template) and at least one set is the energy-saving communication power parameter template. The communication power parameter template may be configured in a number of ways known in the art. The normal communication power parameter template and the energy saving communication power parameter template at least include a UE Specific DRX parameter (defined by 3 GPP), a MICO Indication ═ (Yes or No)), and the like.

At a certain time range t1In the method, the jitter and the time delay of the main UE are respectively or simultaneously lower than a first jitter threshold value J1A first time delay threshold D1(safety alarm threshold); 3. the Power of the uRLLC equipment is lower than a first safety threshold value Power0And the electric quantity alarm appears.
