User Association in Massive MIMO HetNets

open access: yesIEEE Systems Journal, 2017
Massive MIMO and small cell are both recognized as the key technologies for the future 5G wireless systems. In this paper, we investigate the problem of user association in a heterogeneous network (HetNet) with massive MIMO and small cells, where the macro base station (BS) is equipped with a massive MIMO and the picocell BS's are equipped with regular

Dynamic mobility and handover management in software‐defined networking‐based fifth‐generation heterogeneous networks

open access: yesInternational Journal of Network Management, Volume 35, Issue 1, January/February 2025.
This article proposes an optimal next cell selection technique for users in the software‐defined heterogeneous network to tackle the challenges of handover and mobility management. The technique uses linear programming (LP) to facilitate optimal cell selection and reduce the number of user handovers based on multiple parameters, including user ...
