Fundamentals of Energy-Efficient Hardware Configurations for Wireless Links with Sleep Modes
Anders Enqvist, Özlem Tuğfe Demir, Cicek Cavdar +1
In this paper, we examine the energy efficiency (EE) of a base station (BS) with multiple antennas. We use a state-of-the-art power consumption (PC) model that captures the passive…
Energy-Efficient Dual-Band Communication: How to Allocate Traffic to Sub-THz Carriers?
Anders Enqvist, Emil Björnson, Cicek Cavdar
As 6G wireless networks transition toward sub-Terahertz (sub-THz) frequencies to satisfy extreme capacity demands, managing the trade-off between massive bandwidth and power consum…
Sparse Activation for Sustainable Cell-Free Massive MIMO Networks: Less is More
Zhe Wang, Shuaifei Chen, Emil Björnson
Motivated by the vision of making sixth-generation (6G) networks sustainable, we study the sparse antenna/array activation problems in uplink cell-free massive multiple-input multi…
RIS-Assisted Survivable Backhaul Recovery in Small-Cell Systems
Zhenyu Li, Özlem Tuğfe Demir, Emil Björnson +1
The increasing densification of small-cell networks substantially expands cable-based backhaul infrastructure, creating heightened vulnerability to cable link failures. This paper…
Electromagnetic Signal and Information Theory: A Continuous-Aperture Array Perspective
Zhaolin Wang, Chongjun Ouyang, Kuranage Roche Rayan Ranasinghe +4
Emerging wireless systems are evolving toward larger, denser, higher-frequency, and more reconfigurable apertures, which motivates the study of continuous-aperture arrays (CAPAs).…
Harnessing the Freedom of Non-Uniformity in Monostatic ISAC with Antenna Flexibility
Zhe Wang, Mahmoud Zaher, Vitaly Petrov +1
This paper studies flexible non-uniform array design for monostatic integrated sensing and communication (ISAC) systems. An antenna pool is considered at the base station, where ea…
