Thresholds Optimization for One-Bit Feedback Multi-User Scheduling

We propose a new one-bit feedback scheme with scheduling decision based on the maximum expected weighted rate. We show the concavity of the 2-user case and provide the optimal solution which achieves the maximum weighted rate of the users. For the general asymmetric M -user case, we provide a heuristic method to achieve the maximum expected weighted rate. We show that the sum rate of our propos...

Supplementary Material: Online Stochastic Linear Optimization under One-bit Feedback

A. More Strategies for Efficient Implementations Enlarging the Confidence region For a positive definite matrix A ∈ Rd×d, we define ‖x‖1,A = ‖Ax‖1. When studying SLB, Dani et al. (2008) propose to enlarge the confidence region from Ct+1 = { w : ‖w −wt+1‖Zt+1 ≤ √ γt+1 } to C̃t+1 = { w : ‖w −wt+1‖1,Zt+1 ≤ √ dγt+1 } such that the computational cost could be reduced. This idea can be direct incorpor...

Online Stochastic Linear Optimization under One-bit Feedback

In this paper, we study a special bandit setting of online stochastic linear optimization, where only one-bit of information is revealed to the learner at each round. This problem has found many applications including online advertisement and online recommendation. We assume the binary feedback is a random variable generated from the logit model, and aim to minimize the regret defined by the un...

Coordinated User Scheduling Based on Hybrid CSI in Multi-User MIMO Relay System with Limited Feedback

This paper considers coordinated user scheduling in a multi-user two-hop multiinput multi-output relay system with limited feedback. The proposed scheme utilizes a quantized transmit correlation and channel quality information, enabling to achieve both interference mitigation and multi-user diversity (MUD) gain. To this end, we first investigate the effect of quantization error on the statistic...

User Fairness Scheme with Proportional Fair Scheduling in Multi-user MIMO Limited Feedback System

In Multi-user MIMO (MU-MIMO) downlink system, suitable user selection schemes can improve spatial diversity gain. In most of previous studies, it is always assumed that the base station (BS) knows full channel state information (CSI) of each user, which does not consider the reality. However, there are only limited feedback bits in real system. Besides, user fairness is often ignored in most of...
