A system and method for assigning users to a particular sub band in a given time slot in a NOMA system, where whichever pair of users corresponds to the smallest "candidate pair user throughput deviation value", reflecting the aggregate of the respective difference between the average throughput across all users (K) and the known throughput of each of the two users under consideration (k1 and k2),and each user attributed to a sub-band other than said selected sub-band. User pairs for consideration may consider all possible pairs, or may be limited to candidate pairs satisfying together, or comprising one or both users who satisfy a criterion such as channel gain, distance to a target, throughput or a combination of some or all of these factors. The power allocated to each sub-band may beattributed by a waterfilling algorithm. 一种用于在NOMA系统中在给定时隙中将用户指派给特定子带的系统和方法，其中任何一个用户对对应于最小的"候选对用户吞吐量偏差值"，该候选对用户吞吐量偏差值反映了以下两者之间的相应差异的聚合：跨所有用户(K)的平均吞吐量；以及所考虑的两个用户(k1k2)和归属于除了所述所选择的子带之外的子带的每个用户中的每一个的已知吞吐量。所考虑的用户对可以考虑所有可能的对，或者可以被限制
