Embodiment Construction

[0028] Some embodiments herein provide, for example, ways to enable photovoltaic (PV) power input of variable power and size directly to a radio unit and control methods to control this PV power input. PV power input allocation is controlled based on PV power production and power consumption of components within the radio unit. This makes it possible to use more environmentally friendly PV power. This will be explained in more detail below.

[0029] Like reference numerals correspond to like features throughout the figures and text.

[0030] figure 1 is a schematic overview depicting a wireless communication network 100 in which embodiments herein may be implemented. Wireless communication network 100 includes one or more RANs and one or more CNs. Can the wireless communication network 100 use 5G NR, or can also use a variety of other different technologies such as Wi-Fi, LTE, LTE-Advanced, Wideband Code Division Multiple Access (WCDMA), Global System for Mobile Communicat...

Abstract

A method for controlling allotment of power input between at least two PAs of a radio unit for data communication in a wireless communications network is provided. The radio unit has access to Direct Current (DC) power and Photovoltaic (PV) power. The amount of power to be transmitted out from each respective PA out of the at least two PAs established (401 ), and information related to the amount of PV power available is obtained (402). The allotment of power input of DC power and PV power between the at least two Pas is then controlled (404) based on the established amount of power to be transmitted out from each respective PA out of the at least two PAs, and the obtained information related to the amount of PV power available.

Description

technical field [0001] Embodiments herein relate to devices and methods therein. In particular, they relate to controlling the distribution of power input between at least two power amplifiers (PA) of a radio unit used for data communication in a wireless communication network. Background technique [0002] In a typical wireless communication network, wireless devices (also referred to as wireless communication devices, mobile stations, stations (STAs) and / or user equipment (UEs)) Communicates with one or more Core Networks (CN). The RAN covers a geographical area divided into service areas or cell areas (which may also be referred to as beams or beam groups), each served by a radio network node, such as a radio access A node (eg a Wi-Fi access point or a radio base station (RBS)), which in some networks may also be denoted eg as a NodeB, eNodeB (eNB) or gNB as in 5G. A service area or cell area is a geographical area where radio coverage is provided by a radio network no...
