An AoI-oriented Time-Frequency Distributed Access Mechanism in Wireless Sensor Networks with Spectrum Division
Jingwei Liu, Fang Liu, Wing Shing Wong +2
The increasing adoption of spectrum-division techniques enables concurrent uplink transmissions over multiple orthogonal resources, yet low-overhead access design with effective in…
Optimizing Information Freshness of IEEE 802.11ax Uplink OFDMA-Based Random Access
Jingwei Liu, Qian Wang, He Chen
The latest WiFi standard, IEEE 802.11ax (WiFi 6), introduces a novel uplink random access mechanism called uplink orthogonal frequency division multiple access-based random access…
Optimizing AoI at Query in Multiuser Wireless Uplink Networks: A Whittle Index Approach
Jingwei Liu, He Chen
In this paper, we explore how to schedule multiple users to optimize information freshness in a pull-based wireless network, where the status updates from users are requested by ra…
Optimizing Information Freshness in Uplink Multiuser MIMO Networks with Partial Observations
Jingwei Liu, Qian Wang, He Chen
This paper investigates a multiuser scheduling problem within an uplink multiple-input multi-output (MIMO) status update network, consisting of a multi-antenna base station (BS) an…
