Phase difference measurement for carrier phase-based positioning

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, the one or more processors, either alone or in combination, configured to:
• transmit, via the one or more transceivers, to a user equipment (UE), a configuration to obtain a received signal phase difference (RSPD) measurement between a first reference signal resource transmitted by a first entity and one or more second reference signal resources transmitted by one or more second entities, the first reference signal resource comprising one or more first symbols, and the one or more second reference signal resources comprising one or more second symbols;
• and
• receive, via the one or more transceivers, the RSPD measurement from the UE based on the configuration.

A method of wireless communication performed by a user equipment (UE), comprising:

• receiving a first reference signal resource transmitted by a first entity, the first reference signal resource comprising one or more first symbols;
• receiving one or more second reference signal resources transmitted by one or more second entities, the one or more second reference signal resources comprising one or more second symbols;
• and
• determining one or more first received signal phase difference (RSPD) measurements for the one or more second reference signal resources based on a phase of the first reference signal resource and a phase of each of the one or more second reference signal resources.
