Spatial domain measurements for beam based positioning

An apparatus, comprising:

• at least one processor;
• and
• at least one memory including computer program code;
• the at least one memory and the computer code configured to, with the at least one processor, cause the apparatus at least to:
• connect to a network node and a target node with a pair of uplink and/or downlink transmission and/or reception beams;
• receive, at an anchor node, a positioning measurement configuration from the network node;
• compute at least one positioning assistance measurement of the anchor node comprising an angular difference between the pair of uplink and/or downlink transmission and/or reception beam directions based on the positioning measurement configuration;
• receive a positioning report from the target node comprising a positioning assistance measurement associated with the target node and a plurality of anchor nodes connected with the target node;
• and
• determine a second positioning report comprising the positioning assistance measurements of the anchor node and the target node.

An apparatus, comprising:

• at least one processor;
• and
• at least one memory including computer program code;
• the at least one memory and the computer code configured to, with the at least one processor, cause the apparatus at least to:
• establish a plurality of connections to a target node via a plurality of anchor nodes;
• determine, by a network node, a positioning measurement configuration of positioning assistance measurements for the target node and the plurality of anchor nodes;
• and
• dispatch the positioning measurement configuration to at least one of the target node and/or to the plurality of anchor nodes.
