摘要

5G上行链路非正交多址(NOMA)系统的最大能效对智能电网的发展至关重要。在系统信噪比最小、频带利用率最大、用户速率要求最小、单用户发射功率最大的条件下，提出了基于两组用户的NOMA系统中能量效率最大化的功率分配优化问题。在满足用户最小用电量的要求下，计算出用户所需的最小用电量，在约束条件下得到系统的功率分配目标，在此基础上求解系统的最大能效和功率分配问题。

Research on Power Allocation Algorithm for Maximizing Energy Efficiency in Uplink NOMA System of 5G Smart Grid

The maximum energy efficiency of 5G uplink non-orthogonal multiple access (NOMA) systems is crucial to the development of smart grids. Under the conditions of the system’s minimum signal to interference and noise ratio (SINR), maximum frequency band utilization, minimum rate requirement of users and maximum transmission power of a single user, Based on two user groups, the power allocation optimization problem for maximizing energy efficiency in NOMA system is proposed. The minimum power required by the user is calculated under the requirement of satisfying the minimum rate of the user, and then the power allocation target is obtained under the constraint condition, and then the maximum energy efficiency and power allocation of the system are solved based on the algorithm.
