Beam management performed for user equipment in a network. A method is performed by a network node. The method includes collecting performance feedback per beam upon having started to perform a current run of a beam management procedure. The performance feedback is derived from network statistics. The beam management procedure may include determining a candidate beam set from a set of available beams. The beam management procedure may include determining a beam switching command per user equipment for at least some of the user equipment.

Beam management for user equipment in a network

A method for wireless communication is disclosed, wherein an access node is configured to transmit signals using beamforming to a user device, wherein transmitting signals using beamforming comprises transmitting signals using a selected beam of a plurality of available beams, and wherein beam tracking comprises measurements by the user device on a candidate set of beams of the plurality of available beams for beam selection. The method comprises predicting a future trajectory for the user device, and determining the candidate set of beams based on the predicted future trajectory. In some embodiments, determining the candidate set of beams based on the predicted future trajectory comprises giving preference to available beams covering the predicted future trajectory. In some embodiments, determining the candidate set of beams comprises letting a first candidate set of beams associated with a first reliability of the prediction include more available beams not covering the predicted future trajectory than does a second candidate set of beams associated with a second reliability of the prediction when the first reliability is lower than the second reliability. Corresponding apparatus, network node and computer program product are also disclosed.

Determination of candidate set of beams for beam tracking

A power management method of a wireless communication device is disclosed. The wireless communication device comprises a modem for wireless communication and a battery for supplying power to the modem. The method comprises obtaining information regarding a power consumption of the modem as a function of time (the information being provided by the modem during wireless communication), forming power consumption statistics from the obtained information (wherein the power consumption statistics comprise an average power consumption during wireless communication as a function of one or more time parameters), and controlling use of the modem by one or more applications of the wireless communication device based on the power consumption statistics. Corresponding computer program product, arrangement and wireless communication device are also disclosed.
