Both a global reliability and per-user reliability requirements are considered. The two-user case is analyzed in detail, and generalizations to the $K$ -user case are also discussed. The largest second order achievable

Joint Sensing Adaptation and Model Placement in 6G Fabric Computing IEEE J. Sel. Area. Comm. (IF 16.4) Pub Date : 2023-06-05 Yixue Hao, Long Hu, Min Chen
Sensing and computing based on intelligent fabrics can meet the ultra-reliable and low-latency communication (URLLC) needs of sixth-generation wireless (6G) by integrating sensing units into fabric fibers to perceive user data. Although some researchers have designed sensing or computing solutions, such solutions have not been well explored. In this paper, we consider the joint sensing adaptation and

Attention-Aware Resource Allocation and QoE Analysis for Metaverse xURLLC Services IEEE J. Sel. Area. Comm. (IF 16.4) Pub Date : 2023-06-05 Hongyang Du, Jiazhen Liu, Dusit Niyato, Jiawen Kang, Zehui Xiong, Junshan Zhang, Dong In Kim
Metaverse encapsulates our expectations of the next-generation Internet, while bringing new key performance indicators (KPIs). Although conventional ultra-reliable and low-latency communications (URLLC) can satisfy objective KPIs, it is difficult to provide a personalized immersive experience that is a distinctive feature of the Metaverse. Since the quality of experience (QoE) can be regarded as a

Trade Reliability for Security: Leakage-Failure Probability Minimization for Machine-Type Communications in URLLC IEEE J. Sel. Area. Comm. (IF 16.4) Pub Date : 2023-05-31 Yao Zhu, Xiaopeng Yuan, Yulin Hu, Rafael F. Schaefer, Anke Schmeink
How to provide information security while fulfilling ultra reliability and low-latency requirements is one of the major concerns for enabling the next generation of ultra-reliable and low-latency communications service (xURLLC), specially in machine-type communications. In this work, we investigate the reliability-security tradeoff by defining the leakage-failure probability, a metric that jointly

Age of Information in Downlink Systems: Broadcast or Unicast Transmission? IEEE J. Sel. Area. Comm. (IF 16.4) Pub Date : 2023-05-30 Zhifeng Tang, Nan Yang, Parastoo Sadeghi, Xiangyun Zhou
We analytically decide whether the broadcast transmission scheme or the unicast transmission scheme achieves the optimal age of information (AoI) performance of a multiuser system where a base station (BS) generates and transmits status updates to multiple user equipments (UEs). In the broadcast transmission scheme, the status update for all UEs is jointly encoded into a packet for transmission, while

Age of Information Under Frame Slotted ALOHA-Based Status Updating Protocol IEEE J. Sel. Area. Comm. (IF 16.4) Pub Date : 2023-05-30 Zhiling Yue, Howard H. Yang, Meng Zhang, Nikolaos Pappas
We propose a frame slotted ALOHA (FSA)-based protocol for a random access network where sources transmit status updates to their intended destinations. We evaluate the effect of such a protocol on the network’s timeliness performance using the Age of Information (AoI) metric. Specifically, we leverage tools from stochastic geometry to model the spatial positions of the source-destination pairs and

Joint Uplink and Downlink Resource Allocation Toward Energy-Efficient Transmission for URLLC IEEE J. Sel. Area. Comm. (IF 16.4) Pub Date : 2023-05-30 Kang Li, Pengcheng Zhu, Yan Wang, Fu-Chun Zheng, Xiaohu You
Ultra-reliable and low-latency communications (URLLC) is firstly proposed in 5G networks, and expected to support applications with the most stringent quality-of-service (QoS). However, since the wireless channels vary dynamically, the transmit power for ensuring the QoS requirements of URLLC may be very high, which conflicts with the power limitation of a real system. To fulfil the successful URLLC
