Statistical Device Activity Detection for OFDM-based Massive Grant-Free Access

  title={Statistical Device Activity Detection for OFDM-based Massive Grant-Free Access},
  author={Yuhang Jia and Ying Cui and Wuyang Jiang},
Existing works on grant-free access, proposed to support massive machine-type communication (mMTC) for the Internet of things (IoT), mainly concentrate on narrow band systems under flat fading. However, little is known about massive grant-free access for wideband systems under frequency-selective fading. This paper investigates massive grant-free access in a wideband system under frequency-selective fading. First, we present an orthogonal frequency division multiplexing (OFDM)-based massive…

Device Activity Detection for Grant-Free Massive Access Under Frequency-Selective Rayleigh Fading
An orthogo-nal frequency division multiplexing (OFDM)-based grant-free massive access scheme for a wideband system with one M- antenna base station, single-antenna Internet of Things (IoT) devices, and channel taps and an iterative algorithm to obtain a stationary point using optimal techniques is presented.
ML and MAP Device Activity Detections for Grant-Free Massive Access in Multi-Cell Networks
Numerical results show the substantial gains of the proposed designs over well-known existing designs and reveal the importance of explicit consideration of inter-cell interference, the value of prior information, and the advantage of AP cooperation in device activity detection.
Covariance Based Joint Activity and Data Detection for Massive Random Access with Massive MIMO
It is made an observation that in the massive multiple-input multiple-output (MIMO) regime, where the BS is equipped with a large number of antennas, a covariance based detection scheme that solves a maximum likelihood estimation problem is more effective than the approximate message passing (AMP) based compressed sensing approach for sequence detection.

It is shown that in the asymptotic massive multiple-input multiple-output regime, both the missed device detection and the false alarm probabilities for activity detection can always be made to go to zero by utilizing compressed sensing techniques that exploit sparsity in the user activity pattern.
Grant-Free Massive MTC-Enabled Massive MIMO: A Compressive Sensing Approach
An algorithm is designed that jointly detects device activity along with embedded information bits and exploits the structured sparsity introduced by the non-coherent transmission scheme and has superior performance compared with application of the original AMP approach.
Covariance-Based Cooperative Activity Detection for Massive Grant-Free Random Access
Simulation results show that the proposed algorithm is efficient for large-scale activity detection problems while requires shorter pilot sequences compared with the state-of-art algorithms in achieving the same system performance.

This paper adopts a general and tractable model for distributions of pilot states (being transmitted or not), namely the multivariate Bernoulli (MVB) model, which can explicitly specify general correlation among device activities and relation among the states of pilots assigned to one device.
Joint Activity Detection and Channel Estimation for IoT Networks: Phase Transition and Computation-Estimation Tradeoff
A structured group sparsity estimation method to simultaneously detect the active devices and estimate the corresponding channels and a smoothing method to solve the high-dimensional structured estimation problem with a given limited time budget is developed.

This paper considers an approach for simultaneous multipacket channel estimation and reception (SMuCER) with a multicarrier system under frequency-selective fading, where the channel estimation becomes challenging due to frequency- selective fading and different round-trip delay between the devices.
Multi-Cell Sparse Activity Detection for Massive Random Access: Massive MIMO Versus Cooperative MIMO
The numerical results validate the analytic characterization and show that as the number of antennas increases, a massive MIMO system effectively drives the detection error to zero, while as the cooperation size increases, the cooperative MIMo architecture mainly improves the cell-edge user performance.
