QoS-Aware and Routing-Flexible Network Slicing for Service-Oriented Networks
Wei-Kun Chen, Ya-Feng Liu, Yu-Hong Dai +1
In this paper, we consider the network slicing (NS) problem which attempts to map multiple customized virtual network requests (also called services) to a common shared network inf…
An Efficient Benders Decomposition Approach for Optimal Large-Scale Network Slicing
Wei-Kun Chen, Zheyu Wu, Rui-Jin Zhang +3
This paper considers the network slicing (NS) problem which attempts to map multiple customized virtual network requests to a common shared network infrastructure and allocate netw…
Efficient Quantized Constant Envelope Precoding for Multiuser Downlink Massive MIMO Systems
Zheyu Wu, Ya-Feng Liu, Bo Jiang +1
Quantized constant envelope (QCE) precoding, a new transmission scheme that only discrete QCE transmit signals are allowed at each antenna, has gained growing research interests du…
Optimal QoS-Aware Network Slicing for Service-Oriented Networks with Flexible Routing
Wei-Kun Chen, Ya-Feng Liu, Yu-Hong Dai +1
In this paper, we consider the network slicing problem which attempts to map multiple customized virtual network requests (also called services) to a common shared network infrastr…
Towards Efficient Large-Scale Network Slicing: An LP Dynamic Rounding-and-Refinement Approach
Wei-Kun Chen, Ya-Feng Liu, Fan Liu +2
In this paper, we propose an efficient algorithm for the network slicing problem which attempts to map multiple customized virtual network requests (also called services) to a comm…
Joint Power and Admission Control: Non-Convex Approximation and An Effective Polynomial Time Deflation Approach
Ya-Feng Liu, Yu-Hong Dai, Shiqian Ma
In an interference limited network, joint power and admission control (JPAC) aims at supporting a maximum number of links at their specified signal to interference plus noise ratio…
Joint power and admission control via p norm minimization deflation
Ya-Feng Liu, Yu-Hong Dai
In an interference network, joint power and admission control aims to support a maximum number of links at their specified signal to interference plus noise ratio (SINR) targets wh…
On the Complexity of Joint Subcarrier and Power Allocation for Multi-User OFDMA Systems
Ya-Feng Liu, Yu-Hong Dai
Consider a multi-user Orthogonal Frequency Division Multiple Access (OFDMA) system where multiple users share multiple discrete subcarriers, but at most one user is allowed to tran…
