Communication and computing resource joint allocation method for minimizing unloading cost of VR (Virtual Reality) system

Номер: CN116016502A

The invention relates to a communication and computing resource joint allocation method for minimizing the unloading cost of a VR system based on NOMA-MEC in a CCHN, which can utilize a continuous convex approximation algorithm to jointly optimize downlink transmission power pm, n, m and n under the condition that an unloading decision alpha m and cellular resource block selection beta m, n of VR equipment are known. According to the method, the minimum CCHN total calculation unloading cost of the VR equipment under the NOMA-MEC system can be realized by reasonably distributing communication and calculation resources under the condition that the constraint of time delay and energy consumption of the VR equipment is met, and the complexity is relatively low.
