… user whose pilot power is far lower than ρmin or far more than ρmax. Finally, we allocate the
selected user into the group 1 or group 2… users and the remaining available total pilot power …

… In this paper, we aim to address the overlapping beam problem and look for enhanced user
grouping, beam selection, and power allocation schemes for more efficient mmWave MIMO-…

… a user grouping and a power allocation with relatively low complexity. Different from previous
… , the user grouping scheme is designed for considering channel conditions, user locations, …

… Different from the works above, we consider user grouping and jointly optimize HBF and
power allocation. Particularly, we consider a single-cell downlink system, where the base …

… mance, the formulated power allocation problem is solved by a … the random user structure
and the fixed power allocation. … orthogonal groups, then the BS can server these groups with …

… users in uplink NOMA. Then, we obtain a game model for the joint user association, grouping
and power allocation (… the goal to minimize total transmit power. Furthermore, we prove the …

… We study the problems of user grouping and power allocation in the downlink of a multi-carrier …
Users are grouped first and then power is allocated. For user grouping, the user grouping …

… group of users. To reduce the complexity of NOMA configuration, we adopt a fixed power
allocation scheme and focus on a group of two users … the two users by allocating different power …

… subproblems : user grouping and power allocation. Based on the model proposed above,
we can know that user grouping and power allocation algorithms directly affect user fairness …

… the user grouping problem for NOMA systems in stochastic environments. Thereafter, we use
the consequent groupings to infer the power allocation … user grouping and power allocation …
