Signaling and configuration for multi antenna/port prs transmission and reception

A method for positioning, comprising:

• transmitting, from a user equipment (UE), a UE capability message indicating a capability of the UE to process one or more positioning reference signals (PRS) transmitted from one or more transmission antennas and received at one or more reception antennas of the UE;
• receiving, at the UE, assistance data comprising information for processing the one or more PRS transmitted from the one or more transmission antennas based on the UE capability message;
• receiving, at the one or more reception antennas of the UE, the one or more PRS from the one or more transmission antennas;
• and
• obtaining one or more measurements based on the one or more PRS and associating each of the one or more measurements with one of the one or more transmission antennas as a PRS source antenna and one of the one or more reception antennas as a PRS reception antenna.

A transmission/reception point (TRP), comprising:

• one or more memories;
• one or more transmission antennas;
• one or more transceivers;
• and
• one or more processors, communicatively coupled to the one or more memories and the one or more transceivers, configured to:
• transmit, via the one or more transceivers, a TRP capability message indicating a capability of the TRP to transmit one or more positioning reference signals (PRS) from the one or more transmission antennas;
• receive, via the one or more transceivers, a PRS resource configuration message comprising information for transmitting PRS using the one or more transmission antennas based on the TRP capability message;
• transmit, using the one or more transmission antennas, the one or more PRS based on the PRS resource configuration message, wherein one or more identifiers for the one or more PRS incorporates identifiers of the one or more transmission antennas as one or more sources of the one or more PRS.

A method for positioning, comprising:

• transmitting, from a transmission/reception point (TRP), a TRP capability message indicating a capability of the TRP to transmit one or more positioning reference signals (PRS) from one or more transmission antennas of the TRP;
• receiving, at the TRP, a PRS resource configuration message comprising information for transmitting PRS using the one or more transmission antennas based on the TRP capability message;
• and
• transmitting, using the one or more transmission antennas of the TRP, the one or more PRS based on the PRS resource configuration message, wherein an identifier for the one or more PRS incorporates identifiers of the one or more transmission antennas as one or more sources of the one or more PRS.

A network entity, comprising:

• one or more memories;
• one or more transceivers;
• and
• one or more processors, communicatively coupled to the one or more memories and the one or more transceivers, configured to:
• receive, from a user equipment (UE), a UE capability message indicating a capability of the UE to process one or more positioning reference signals (PRS) transmitted from one or more transmission antennas and received at one or more reception antennas of the UE;
• receive, from a transmission/reception point (TRP), a TRP capability message indicating a capability of the TRP to transmit the one or more PRS from the one or more transmission antennas;
• determine a PRS resource configuration based on the UE capability message and the TRP capability message;
• send, via the one or more transceivers to the TRP, a PRS resource configuration message comprising information for transmitting PRS using the one or more transmission antennas based on the TRP capability message;
• and
• send, via the one or more transceivers to the UE, assistance data comprising information for processing the PRS transmitted from the one or more transmission antennas based on the UE capability message.
