Apparatus for configuring reference signal beams based on accuracy of user equipment localization

A user node, comprising:

• a memory;
• and
• a processor coupled to the memory, the memory storing instructions, which, when executed by the processor, cause the processor to:
• determine a movement measurement value of the user node, the movement measurement value being based on one or more of a change in location and a change in orientation of the user node;
• transmit the movement measurement value to a network node;
• receive, from the network node, information on a configuration of radio beams to be used for a second localization operation of the user node, the configuration of the radio beams being based on the determined movement measurement value and an accuracy value associated with a first localization operation of the user node, the accuracy value being determined by the network node based on a comparison between a pre-determined value and a rate of change of an angle, the angle being an angle of a radio beacon signal transmitted from the user node in the first localization operation relative to the network node;
• and
• use the radio beams for either transmission or reception in the second localization operation of the user node.

A method comprising:

• localizing, by a network node, a user node in a first localization operation carried out at a first frequency;
• determining, by the network node, an accuracy value associated with the first localization operation;
• adjusting, by the network node, at least one beam parameter for radio beams to be used in a second localization operation based on the determined accuracy value, the second localization operation carried out at a second frequency that is greater than the first frequency;
• and
• determining, by the network node, the accuracy value associated with the first localization operation, including
• tracking a rate of change of an angle of a radio beacon signal transmitted from the user node relative to the network node;
• if the rate of change of the angle exceeds a pre-determined value, assigning a first value to the accuracy value, the first value being lower than a previous accuracy value;
• and
• if the rate of change is less than the pre-determined value, assigning a second value to the accuracy value, the second value being higher than a previous accuracy value.
