• ### Downlink Resource Allocation Under Time-Varying Interference: Fairness and Throughput Optimality

Publication Year: 2018, Page(s):722 - 735
| |PDF (1838 KB) | HTML

We address the problem of downlink resource allocation in the presence of time-varying interference. We consider a scenario where users served by a base station face interference from a neighboring base station. We model the interference from the neighboring base station as an ON/OFF renewal process, that arises due to its idle and busy cycles. The users feedback their downlink signal to interfere...

• ### Cache-Enabled Physical Layer Security for Video Streaming in Backhaul-Limited Cellular Networks

Publication Year: 2018, Page(s):736 - 751
| |PDF (1416 KB) | HTML

In this paper, we propose a novel wireless caching scheme to enhance the physical layer security of video streaming in cellular networks with limited backhaul capacity. By proactively sharing video data across a subset of base stations (BSs) through both caching and backhaul loading, secure cooperative joint transmission of several BSs can be dynamically enabled in accordance with the cache status...

Publication Year: 2018, Page(s):752 - 765
| |PDF (918 KB) | HTML

Millimeter-wave (mm-wave) communications plays an important role in future cellular networks because of the vast amount of spectrum available in the underutilized mm-wave frequency bands. To overcome the huge free space omnidirectional path loss in those frequency bands, the deployment of a very large number of antenna elements at the base station is crucial. The complexity, power consumption, and... View full abstract»

Publication Year: 2018, Page(s):766 - 778
| |PDF (2012 KB) | HTML

User-centric base station (BS) cooperation has been regarded as an effective solution for improving network coverage and throughput in next-generation wireless systems. However, it also introduces more complicated handoff patterns, which may potentially degrade user performance. In this paper, we aim to theoretically quantify the tradeoff between handoff cost and data rate. Two user-centric cluste... View full abstract»

| |PDF (1826 KB) | HTML

One of the most promising approaches to overcoming the uncertainty of millimeter wave (mm-wave) communications is to deploy dual-mode small base stations (SBSs) that integrate both mm-wave and microwave ( $mu text{W}$ ) frequencies. In this paper, a novel approach to analyzing and managing mobility in joint mmwave– View full abstract»

• ### Compressed-Sensing Assisted Spatial Multiplexing Aided Spatial Modulation

Publication Year: 2018, Page(s):794 - 807
| |PDF (2175 KB) | HTML

Spatial-multiplexing aided spatial modulation (SMx-SM) is proposed, which intrinsically amalgamates the concept of vertical bell labs space-time (V-BLAST) and SM to attain a high transmission rate, despite its low number of radio frequency (RF) chains at the transmitter. Specifically, in the SMx-SM scheme, the transmit antennas are partitioned into groups and the SM technique is applied individual... View full abstract»

Publication Year: 2018, Page(s):808 - 821
| |PDF (1363 KB) | HTML

This paper analyzes the connection between the protocol and physical interference models in the setting of Poisson wireless networks. A transmission is successful under the protocol model if there are no interferers within a parameterized guard zone around the receiver, while a transmission is successful under the physical model if the signal to interference plus noise ratio at the receiver is abo...

• ### Secure Transmission in Linear Multihop Relaying Networks

Publication Year: 2018, Page(s):822 - 834
| |PDF (1356 KB) | HTML

This paper studies the design and secrecy performance of linear multihop networks, in the presence of randomly distributed eavesdroppers in a large-scale 2-D space. Depending on whether there is feedback from the receiver to the transmitter, we study two transmission schemes: an ON–OFF transmission (OFT) and a non-ON–OFF transmission (NOFT). In the OFT scheme, transmission is suspend... View full abstract»

• ### Complementary Coded Scrambling Multiple Access and Its Performance in Downlink MIMO Channels

Publication Year: 2018, Page(s):835 - 847
| |PDF (1753 KB) | HTML

In a traditional complementary coded CDMA (CC-CDMA) system, signals are spread using the direct sequence (DS) technique to suppress multipath interference (MI) and multiple access interference (MAI). However, DS spreading suffers from very poor bandwidth efficiency. This paper proposes a scrambling-based CC-CDMA system, namely complementary coded scrambling multiple access (CCSMA). A CCSMA system ... View full abstract»

• ### Performance Analysis of Near-Optimal Energy Buffer Aided Wireless Powered Communication

Publication Year: 2018, Page(s):863 - 881
| |PDF (2761 KB) | HTML

In this paper, we consider a wireless powered communication system, where an energy harvesting (EH) node harvests energy from a radio frequency (RF) signal broadcasted by an access point (AP) in the downlink (DL). The node stores the harvested energy in an energy buffer and uses the stored energy to transmit data to the AP in the uplink (UL). We investigate two simple online transmission policies ...

• ### An Information-Theoretic Analysis of the Gaussian Multicast Channel With Interactive User Cooperation

Publication Year: 2018, Page(s):899 - 913
| |PDF (1756 KB) | HTML

We consider the transmission of a common message from a transmitter to three receivers over a broadcast channel, referred to as a multicast channel in this case. All the receivers are allowed to cooperate with each other over full-duplex non-orthogonal cooperation links. We investigate the information-theoretic upper and lower bounds on the transmission rate. In particular, we propose a three-rece... View full abstract»

• ### Ergodic Rate of Millimeter Wave Ad Hoc Networks

Publication Year: 2018, Page(s):914 - 926
| |PDF (1140 KB) | HTML

In this paper, we use a stochastic geometry approach to quantify the ergodic rate of each user in an outdoor mm-wave ad hoc network. For a variety of use cases, it is reasonable to assume users will be clustered around a central point (e.g., WiFi hotspot or clusterhead) rather than uniformly distributed. Our results indicate that, in contrast to sub-6-GHz networks, clustered mm-wave ad hoc network... View full abstract»

• ### Power Control for Multi-Cell Networks With Non-Orthogonal Multiple Access

Publication Year: 2018, Page(s):927 - 942
| |PDF (1581 KB) | HTML

In this paper, we investigate the problems of sum power minimization and sum rate maximization for multi-cell networks with non-orthogonal multiple access. Considering the sum power minimization, we obtain closed-form solutions to the optimal power allocation strategy and then successfully transform the original problem to a linear one with a much smaller size, which can be optimally solved by usi...

• ### Blind Channel Estimation and Symbol Detection for Multi-Cell Massive MIMO Systems by Expectation Propagation

Publication Year: 2018, Page(s):943 - 954
| |PDF (1407 KB) | HTML

Massive MIMO systems exploit the favorable propagation condition of the radio channel, whereby the vector-valued channels between the base station (BS) and the terminals become mutually orthogonal. This property is used in a recently-proposed channel estimation method for multi-cell massive MIMO systems based on the eigenvalue decomposition (EVD) of the correlation matrix of the received vectors. ...

| |PDF (1361 KB) | HTML

Using a network of cache enabled small cells, traffic during peak hours can be reduced by proactively fetching the content that is most likely to be requested. In this paper, we aim to explore the impact of proactive caching on an important metric for future generation networks, namely, energy efficiency (EE). We argue that, exploiting the spatial repartitions of users in addition to the correlati... View full abstract»

In this paper, we develop Gibbs sampling-based techniques for learning the optimal placement of contents in a cellular network. We consider the situation where a finite collection of base stations are scattered on the plane, each covering a cell (possibly overlapping with other cells). Mobile users request downloads from a finite set of contents according to some popularity distri... View full abstract»

• ### Macrodiversity in Cellular Networks With Random Blockages

Publication Year: 2018, Page(s):996 - 1010
| |PDF (2665 KB) | HTML

Blocking objects (blockages) between a transmitter and receiver cause wireless communication links to transition from line-of-sight (LOS) to non-LOS propagation, which can greatly reduce the received power, particularly at the higher frequencies such as millimeter wave. We consider a cellular network in which a mobile user attempts to connect to two or more base stations (BSs) simultaneously, to i... View full abstract»

• ### Multi-Channel Resource Allocation Toward Ergodic Rate Maximization for Underlay Device-to-Device Communications

Publication Year: 2018, Page(s):1011 - 1025
| |PDF (1531 KB) | HTML

In underlay device-to-device (D2D) communications, a D2D pair reuses the cellular spectrum causing interference to regular cellular users. Maximizing the performance of underlay D2D communications requires joint consideration for the achieved D2D rate and the interference to cellular users. In this paper, we consider the D2D power allocation optimization over multiple resource blocks (RBs), aimed ... View full abstract»
