According to one aspect, a method and an energy control device are provided for estimating electricity consumption during one or more transmission intervals of a transmission site or part of a transmission site. Said site comprises a scheduler for scheduling assignments, and a set of radio transmitters having known radio efficiency &#x3b7;. Said method comprises a step of estimating scheduled transmission electricity consumption Ebased on a quotient of a sum Pof scheduled radio transmission powers Pand the radio efficiency &#x3b7;. An energy management control method based on information from the scheduler to control the alternative energy sources on site is provided, wherein said information is depending on radio traffic load. The energy control method for every TTI for efficient and effective control that is based on the real traffic situation.

Energy control devices and methods for energy management in a transmission site of a wireless communication network

Disclosed is a power supply unit, PSU, for wirelessly powering components of a radio base station, RBS, such as a radio unit, RU, transmission units (TMR) and a baseband digital unit, BDU. The PSU includes a TX coil for generating an energy field that is used to induce a current and voltage in an RX coil that is part of a component of the base station. The need for power cables, which are inefficient at transferring energy, is therefore greatly reduced. Hence, the energy efficiency of the RBS is increased.
