Toward a Quiet Wireless World: Multi-Cell Pinching-Antenna Transmission

Zhiguo Ding

TL;DR

This letter demonstrates that the use of multi-cell pinching-antenna transmission leads to a quiet wireless world because each transceiver pair can be positioned in close proximity, and hence the users'QoS requirements can be met with only low transmit power, i.e., via ``whispering"rather than high-power transmission.

Abstract

Conventional-antenna-based multi-cell interference management can lead to excessive power consumption. For example, in order to serve those users which are close to the cell edge, base stations often must transmit at very high power levels to overcome severe large-scale path-loss, i.e., the base stations have to ``shout" at the users to realize the users' target quality of service (QoS). This letter focuses on the application of pinching antennas to multi-cell interference management and demonstrates that the use of multi-cell pinching-antenna transmission leads to a quiet wireless world. In particular, each transceiver pair can be positioned in close proximity, and hence the users' QoS requirements can be met with only low transmit power, i.e., via ``whispering" rather than high-power transmission.
