A system in a wireless network comprising a tower, a first radio unit, a power supply unit, a supplementary power source and a power control unit arranged to supply electric power to the first radio unit. The power control unit is operative to obtain a scheduled power demand related to an amount of electric power required in the first radio unit for transmissions scheduled in an imminent time interval as a resource block or subframe. The power control unit is further operative to supply electric power to the first radio unit from the power supply unit if the power demand does not exceed a power threshold, or from the power supply unit and the supplementary power source if the power demand exceeds the power threshold.

A power control method and apparatus and a terminal device are disclosed, which pertain to the field of communication technologies.

Facilitating adaptive power spectral density with chromatic spectrum optimization in advanced networks (e.g., 5G, 6G, and beyond) is provided herein. Operations of a method can comprise evaluating, by a system comprising a processor, a capture rate of mobile devices within a radio access network. The capture rate is representative of a quantity of mobile devices using a millimeter wave spectrum of the radio access network. The method also can comprise facilitating, by the system, an adjustment to a power spectral density of the radio access network based on a determination that the capture rate fails to satisfy a target capture rate of mobile devices using the millimeter wave spectrum.

Wireless communications systems and methods related to listen-before-talk (LBT) are provided. A first wireless communication device performs an LBT in a channel to contend for a first transmission opportunity (TXOP). The first wireless communication device receives, from a second wireless communication device, a first reservation signal reserving a second TXOP in the channel in response to the LBT, the second TXOP being different from the first TXOP. The first wireless communication device adjusts a signal detection threshold based on transmit power information associated with at least one of the first wireless communication device, the second wireless communication device, first data traffic to be communicated in the first TXOP, or second data traffic to be communicated in the second TXOP. The first wireless communication device determines whether to yield channel access during the second TXOP based on a signal measurement of the first reservation signal and the adjusted signal detection threshold.
