A method performed by a control node for a radio access network. The control node may select an energy source from a plurality of energy sources connected to a base station based on selecting an energy rate of one of the energy sources correlated in time with a radio traffic power usage of the base station. The selection may be made from a plurality of energy rates for the plurality of energy rates correlated in time for each energy source with a radio traffic power usage of the base station. The selected energy rate may improve at least one operating parameter of the selected energy source. The control node may activate the selected energy source for use by the base station.

A transmitter including two radio transceivers and a controller is provided. The first radio transceiver supports a first number of Spatial Streams (SS) for a first Transmission (Tx) opportunity of wireless transmission to a receiver. The second radio transceiver supports a second number of SS for a second Tx opportunity of wireless transmission to the receiver. The first Tx opportunity starts earlier than the second Tx opportunity. The controller determines whether the power consumption of SS utilization in the first and second Tx opportunities exceeds a threshold, and if so, performs one of the following: deferring the second Tx opportunity until the first Tx opportunity ends; and aborting the first Tx opportunity when the second Tx opportunity starts.

Methods, systems, and devices for wireless communications are described. Generally, a base station may transmit downlink control channel messages during one or more monitoring occasions using a first set of resources. The base station may perform a directional listen-before-talk (LBT) procedure on one or more beams. The base station may transmit a control message including instructions to modify monitoring of a wireless channel using the first set of resources over a second set of resources. A UE may monitor, using the first set of resources, for downlink control channel signaling during monitoring occasions according to a first monitoring pattern. The UE may receive, using the second set of resources, the control message, and may monitor the wireless channel according a second monitoring pattern based on the received control message.

A server includes a processor configured to execute instructions stored on a memory to cause the server to: receive a client position signal; predict a future position of a client device based on a client device position signal providing location and velocity information about the client device; instruct a first access point device to provide a first Wi-Fi hotspot network with a first SSID, currently in use by the client device with another access point device, based on the predicted future position of the client device; and instruct a second access point device, which was previously providing a second Wi-Fi hotspot network with the first SSID, to stop providing the second Wi-Fi hotspot network with the first SSID after instructing the first access point device to provide the first Wi-Fi hotspot network with the first SSID.

A method and power control unit for supplying electric power to a first radio unit of a network node in a wireless network. The power control unit obtains 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 such as a resource block or subframe. Then, electric power is supplied to the first radio unit from a power supply unit if the power demand does not exceed a power threshold, or from the power supply unit and a supplementary power source if the power demand exceeds the power threshold. The supplementary power source may comprise a battery that can be connected or disconnected for successive time intervals depending on the scheduled power demand which may fluctuate greatly depending on the first radio unit's transmissions.
