Methods, access node and network node for addressing ambiguities in angle of arrival estimation

An access node comprising a radio interface and processing circuitry configured to:

• transmit, to a wireless device, an instruction to transmit reference signals for positioning measurements;
• perform positioning measurements including measuring a plurality of Angle of Arrival (AoA) values for the reference signals;
• and
• transmit, to a network node, a positioning measurement response including the plurality of AoA values.

A method performed by a network node, the method comprising:

• transmitting an instruction for a wireless device to transmit reference signals for positioning measurements;
• transmitting, to an access node, a positioning measurement request;
• and
• receiving, from the access node, a positioning measurement response including a plurality of Angle of Arrival (AoA) values.
