Query: Robotic Communications for 5G and Beyond: Challenges and Research
  Opportunities   The ongoing surge in applications of robotics brings both opportunities and
challenges for the fifth-generation (5G) and beyond (B5G) of communication
networks. This article focuses on 5G/B5G-enabled terrestrial robotic
communications with an emphasis on distinct characteristics of such
communications. Firstly, signal and spatial modeling for robotic communications
are presented. To elaborate further, both the benefits and challenges derived
from robots' mobility are discussed. As a further advance, a novel simultaneous
localization and radio mapping (SLARM) framework is proposed for integrating
localization and communications into robotic networks. Furthermore, dynamic
trajectory design and resource allocation for both indoor and outdoor robots
are provided to verify the performance of robotic communications in the context
of typical robotic application scenarios.
