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 estimating at least one of a distance from the access node to the user device and a velocity parameter of the user device, and adjusting one or more of a beam tracking measurement frequency, a beam tracking measurement periodicity, the beam tracking measurement period, and a beam tracking measurement interval based on at least one of the estimated distance from the access node to the user device and the estimated velocity parameter of the user device. In some embodiments, adjusting one or more of the beam tracking measurement frequency, the beam tracking measurement periodicity, the beam tracking measurement period, and the beam tracking measurement interval is further based on a load of the access node and/or on a priority of the user device. Corresponding apparatus, network node and computer program product are also disclosed.

Beam tracking measurement control

Methods of a first communication device and of a server are disclosed, for enabling inbound Internet protocol (IP) traffic to the first communication device. The server is associated with an operator network and with a wake-up server identity. The first communication device has an operator specific device identity related to the operator network and is subject to network address translation (NAT). A wake-up registration request is transmitted by the first communication device to the server and the server provides a wake-up identifier to the first communication device for triggering a wake-up action for enabling the inbound IP traffic. The wake-up identifier comprises at least a first part indicative of a wake-up device identity and a second part indicative of the wake-up server identity.

Remote wake-up of a device behind a NAT

There is provided mechanisms for locating wireless devices. A method is performed by a network operator node of cells. The method comprises obtaining an indication to locate wireless devices in a geographical area from a surveillance center node (s). The method comprises initiating a change of logical group area identity of those of its cells that at least partly overlap with the geographical area (s), thereby initiating location reporting from those wireless devices located in the geographical area that are in idle mode. The method comprises, in response thereto, receiving location indicating information from the wireless devices in the geographical area (s).
