Methods and user equipment, radio transmitter and network node for managing positioning reference signals

A method, performed by a network node, for configuring positioning reference signals, wherein the method comprises:

• sending, from the network node to a user equipment, a reception configuration of positioning reference signals, wherein the reception configuration comprises a cell identity relating to a radio transmitter and an identifier for determining of positioning reference signals that the user equipment receives from the radio transmitter, wherein the cell identity comprises one of a physical cell identity and an extended cell identity, and wherein the identifier for determining of positioning reference signals is based on a cell portion identifier that uniquely identifies a cell portion within a cell, and
• sending, from the network node to the radio transmitter, a transmit configuration of positioning reference signals, wherein the transmit configuration comprises the cell identity and the identifier.

A radio transmitter configured for managing positioning reference signals, wherein the radio transmitter is configured for:

• receiving, from a network node, a transmit configuration of the positioning reference signals, wherein the transmit configuration comprises a cell identity relating to the radio transmitter and an identifier for determining of positioning reference signals, wherein the cell identity comprises one of a physical cell identity and an extended cell identity, and wherein the identifier for determining of positioning reference signals is based on a cell portion identifier that uniquely identifies a cell portion within a cell,
• determining, by the radio transmitter, the positioning reference signals to send to a user equipment, the positioning reference signals determined based on the cell identity and the identifier for determining of positioning reference signals received in the transmit configuration from the network node, and
• sending the positioning reference signals from the radio transmitter to a user equipment.

A network node configured for configuring positioning reference signals, wherein the network node is configured for:

• sending, from the network node to a user equipment, a reception configuration of positioning reference signals, wherein the reception configuration comprises a cell identity relating to a radio transmitter and an identifier for determining of positioning reference signals that the user equipment receives from the radio transmitter, wherein the cell identity comprises one of a physical cell identity and an extended cell identity, and wherein the identifier for determining of positioning reference signals is based on a cell portion identifier that uniquely identifies a cell portion within a cell, and
• sending, from the network node to the radio transmitter, a transmit configuration of positioning reference signals, wherein the transmit configuration comprises the cell identity and the identifier.
