Coordinating Multiple Intelligent Reflecting Surfaces without Channel Information
Fan Xu, Jiawei Yao, Wenhai Lai +4
Conventional beamforming methods for intelligent reflecting surfaces (IRSs) or reconfigurable intelligent surfaces (RISs) typically entail the full channel state information (CSI).…
A Linear Time Algorithm for the Optimal Discrete IRS Beamforming
Shuyi Ren, Kaiming Shen, Xin Li +2
It remains an open problem to find the optimal configuration of phase shifts under the discrete constraint for intelligent reflecting surface (IRS) in polynomial time. The above pr…
Configuring Intelligent Reflecting Surface with Performance Guarantees: Optimal Beamforming
Yaowen Zhang, Kaiming Shen, Shuyi Ren +3
This work proposes linear time strategies to optimally configure the phase shifts for the reflective elements of an intelligent reflecting surface (IRS). Specifically, we show that…
Configuring Intelligent Reflecting Surface with Performance Guarantees: Blind Beamforming
Shuyi Ren, Kaiming Shen, Yaowen Zhang +3
This work gives a blind beamforming strategy for intelligent reflecting surface (IRS), aiming to boost the received signal-to-noise ratio (SNR) by coordinating phase shifts across…
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…
