Terminal apparatus, location server, and communication method

A positioning measurement method performed by a terminal apparatus, comprising:

• receiving, from a location server, a positioning reference signal (PRS) resource configuration;
• receiving, from a serving cell based on the PRS resource configuration, a first PRS resource;
• and
• receiving, from a neighboring cell based on the PRS resource configuration, a second PRS resource;
• and
• determining,
• a reference signal time difference (RSTD) at least based on one of a reception timing of the first PRS resource and a reception timing of the second PRS resource;
• wherein the first PRS resource is configured with a first subcarrier spacing and the second PRS resource is configured with a second subcarrier spacing;
• the first PRS resource is configured with a first Quasi co-located (QCL) information for determining a first spatial receiving filter for receiving the first PRS resource by the terminal apparatus;
• the second PRS resource is configured with a second QCL information for determining a second spatial receiving filter for receiving the second PRS resource by the terminal apparatus;
• the first QCL information being different from the second QCL information.

A method for positioning a terminal apparatus performed by a location server, comprising:

• receiving, from a base station, a first positioning reference signal (PRS) configuration for a first base station transmit point and a second PRS configuration for a second base station transmit point;
• and
• transmitting, to the terminal apparatus, a third PRS configuration, wherein, the third PRS configuration includes:
• a first PRS resource determined from the first PRS configuration, the first PRS resource is configured with a first subcarrier spacing and a first Quasi co-located (QCL) information;
• and
• a second PRS resource determined from the second PRS configuration, the second PRS resource is configured with a second subcarrier spacing and a second QCL information.
