Abstract
This paper evaluates the network performance of a cellular system operating at 100 GHz with bandwidth of around 3 GHz under a dynamic transmission and reception point (TRP)-side discontinuous transmission (DTX) regime. The use of sub-terahertz (THz) bands is envisioned as a means to achieve higher data rates in sixth-generation (6G) systems. However, in this network setup, the power consumption at TRPs' radio components packed with several antenna elements significantly increases due to the very high processing burden in such a wide bandwidth. A TRP-side DTX method is proposed to avoid overheating issues, which controls the amount of downlink slot transmissions while guaranteeing cell-specific reference signaling. Simulation results considering different DTX settings and traffic loads are presented and discussed. Results show that the considered sub-THz system with the proposed DTX method can provide higher data rates and close to the same spectral efficiency compared to a typical baseline millimeter wave (mmWave) system operating at 28 GHz with 400 MHz bandwidth. It was possible to reach close to 7 times higher data rates in the simulated system utilizing the dynamic DTX method, compared to a theoretical data rate increase of 7.6 times based solely on bandwidth comparison.
期刊介绍：
The scope of the Transactions is threefold (which was approved by the IEEE Periodicals Committee in 1967) and is published on the journal website as follows: Communications: The use of mobile radio on land, sea, and air, including cellular radio, two-way radio, and one-way radio, with applications to dispatch and control vehicles, mobile radiotelephone, radio paging, and status monitoring and reporting. Related areas include spectrum usage, component radio equipment such as cavities and antennas, compute control for radio systems, digital modulation and transmission techniques, mobile radio circuit design, radio propagation for vehicular communications, effects of ignition noise and radio frequency interference, and consideration of the vehicle as part of the radio operating environment. Transportation Systems: The use of electronic technology for the control of ground transportation systems including, but not limited to, traffic aid systems; traffic control systems; automatic vehicle identification, location, and monitoring systems; automated transport systems, with single and multiple vehicle control; and moving walkways or people-movers. Vehicular Electronics: The use of electronic or electrical components and systems for control, propulsion, or auxiliary functions, including but not limited to, electronic controls for engineer, drive train, convenience, safety, and other vehicle systems; sensors, actuators, and microprocessors for onboard use; electronic fuel control systems; vehicle electrical components and systems collision avoidance systems; electromagnetic compatibility in the vehicle environment; and electric vehicles and controls.
