On RRH Placement for Multi-User Distributed Massive MIMO Systems
IEEE Access, 2018 In a distributed massive multiple-input multiple-output (DM-MIMO) system, a large number of antennas are distributed across multiple remote radio heads (RRHs) within the coverage area.

Resource Efficient Allocation and RRH Placement for Backhaul of Moving Small Cells [PDF]
IEEE Access, 2019 Mobile users suffer from deteriorating signal quality due to vehicle penetration losses. To solve this, small cells are deployed within the vehicles to improve the Quality of Service (QoS). These small cells called moving small cell access points (MSAPs),

Joint Precoding and RRH Selection for Green MIMO C-RAN [PDF]
2016 IEEE Global Communications Conference (GLOBECOM), 2016 This paper jointly optimizes the precoding matrices and the set of active remote radio heads (RRHs) to minimize the network power consumption for a cloud radio access network (C-RAN) where both the RRHs and users all have multiple antennas. Both users’ rate requirements and per-RRH power constraints are considered. Due to these conflicting constraints,

IEEE Transactions on Network and Service Management, 2017 An inefficient utilization of network resources in a time-varying traffic environment often leads to load imbalances, high call-blocking events and degraded quality of service (QoS). This paper optimizes the QoS of a cloud radio access network (C-RAN) by investigating load balancing solutions.
