A new Power Efficient – Delay Aware Downlink Algorithm for 3GPP LTE Cellular Networks [PDF]
Scheduling in downlink transmission in long term evolution (LTE) is a very important process accomplished in the eNodeB. Through the scheduling process, the network dynamically allocates the available radio Resource Blocks (RBs) to users based on the ...

Resource Allocation for CoMP in Cellular Networks With Base Station Sleeping
Base station sleeping (BSS) can result in significant reduction in energy consumption of cellular networks during low traffic conditions. We show that the coverage loss due to BSS can be compensated via coordinated multi-point (CoMP) -based transmission ...

Massive MU-MIMO downlink TDD systems with linear precoding and downlink pilots [PDF]
We consider a massive MU-MIMO downlink time-division duplex system where a base station (BS) equipped with many antennas serves several single-antenna users in the same time-frequency resource. We assume that the BS uses linear precoding for the transmission.

Modeling of Downlink Interference in Massive MIMO 5G Macro-Cell
Multi-beam antenna systems are the basic technology used in developing fifth-generation (5G) mobile communication systems. In practical implementations of 5G networks, different approaches are used to enable a massive multiple-input-multiple-output ...

Downlink and Uplink Intelligent Reflecting Surface Aided Networks: NOMA and OMA
Intelligent reflecting surfaces (IRSs) are envisioned to provide reconfigurable wireless environments for future communication networks. In this paper, both downlink and uplink IRS-aided non-orthogonal multiple access (NOMA) and orthogonal multiple ...

A Distributed Interference Alignment Approach Based on Grouping in Heterogeneous Network
To effectively mitigate interference and improve the performance, we propose a grouping-based two-stage distributed interference alignment (GTDIA) scheme for a two-layered heterogeneous network (HetNet) in multi-user multiple-input-multiple-output (MIMO)
