Given the total power constraint and the non-negative power for the NOMA users, the final power allocation for the high-speed user is determined as the first formula. After determining the power for V0 , the remaining power can be allocated to NOMA users. The allocated power for the i-th user becomes the second formula.Although Assumption 1 provides a simple framework to analyze the optimization problem, the bit rates of all NOMA users may not be exactly the same due to a variety of factors in real vehicular communication, e.g. distance from the user to the BS etc. According to the current analysis, this assumption provides a reasonable starting point and makes a more feasible derivation of the closed-form solution.
