In one aspect of the present disclosure, a user equipment has a processor and a memory including computer program code, where the memory and the computer program code are configured, with the processor, to cause the user equipment to receive from a network node at least one beam-specific mobility parameter associated with at least one respective candidate beam in a serving cell; to switch in the serving cell to a new beam among the at least one candidate beam; and to select a beam-specific mobility parameter associated with the new beam. In another aspect of the present disclosure, a network node has a processor and a memory including computer program code, where the memory and the computer program code are configured, with the processor, to cause the network node to preconfigure at least one beam-specific mobility parameter associated with at least one respective candidate beam in a serving cell; and to send the at least one beam-specific mobility parameter to a user equipment.

Method for utilizing beam-specific cell-individual offsets in a user equipment

There are provided measures for improvement of coverage hole analysis. Such measures exemplarily include detecting a radio link failure, producing a failure report including information indicative of a radio condition during a time period between said radio link failure and a successful establishment of a radio link, detecting said successful establishment of said radio link, and transmitting, after detection of said successful establishment of said radio link, said failure report.

Coverage hole analysis

The present invention provides apparatuses, methods, computer programs, computer program products and computer-readable media regarding signaling physical cell identifier problems. Certain aspects of the present invention include receiving, at a network node, information regarding a suspected identifier problem from a first base station, the information indicating the suspected identifier problem between the first base station and a second base station, and analyzing the suspected identifier problem based on the received information.

Signaling physical cell identifier problems

There is provided a method and an apparatus for determining an adjustment of a tilt angle (&#x3b1;) for a beam emitted from an antenna () of a base station () which is serving a vertically sectorized cell () of a cellular radio telecommunication network. The method comprises (a) configuring user equipments () being located in the vertically sectorized cell () with dedicated measurements, (b) collecting the dedicated measurements for a specific time interval, (c) obtaining a spatial user equipment distribution among a first sector () of the cell () and a second sector () of the cell () based on the collected dedicated measurements, (d) ascertaining an optimized spatial overlap region between the first sector () and the second sector () based on the obtained spatial user equipment distribution, and (e) determining the adjustment of the tilt angle (&#x3b1;) based on the ascertained optimized spatial overlap region.

Determining an adjustment of a tilt angle for an antenna serving a vertically sectorized cell of a radio network

Systems and techniques for antenna optimization are described. Information such as statistics relating to conditions are collected, and evaluated against specified criteria in an iterative process. An antenna tilt decision is made based on the evaluation and validated to determine if it should be retained or repeated, or if the tilt should be returned to a previous state.
