Carrier aggregation positioning

An apparatus comprising:

• a processor;
• and
• a memory comprising computer-executable instructions that, when executed by the processor, cause the apparatus to perform the following operations:
• obtaining a request for the following:
• a component carrier (CC) ranking, measuring positioning measurements (PMs) and one or more received signal time differences (RSTDs), and for measuring a combined carrier aggregation error (CAE) of CCs configured for the apparatus in a mobile communication network, wherein the combined CAE is indicative of a total of errors resulting from a transmit error, receive error, and a processing of the CCs;
• obtaining, based on the request, one or more positioning reference signals (PRS) and one or more sounding reference signals (SRSs) of the one or more CCs;
• determining the PMs or the one or more RSTDs based on a respective PM for a certain CC of the CCs for which at least the PRSs and the SRSs are obtained, or on a respective RSTD of a certain CC of the CCs for which at least the PRSs and the SRSs are obtained;
• determining the CC ranking indicative of a weighting of the CCs based on the PRSs and the SRSs;
• determining the combined CAE based on the following:
• the PRSs and the SRSs;
• the CC ranking, the transmit error, and the receive error of respective CCs;
• and on the weighting of a respective CC of the CCs and the PMs or RSTDs;
• and
• providing the determined combined CAE to a second apparatus for determining a position of the apparatus based on the combined CAE, the second apparatus being a location management function (LMF) of a base station.

A method comprising:

• obtaining, by a user equipment (UE), a request for the following:
• a component carrier (CC) ranking, measuring positioning measurements (PMs) and one or more received signal time differences (RSTDs), and for measuring a combined carrier aggregation error (CAE) of CCs configured for the apparatus in a mobile communication network, wherein the combined CAE is indicative of a total of errors resulting from a transmit error, receive error, and a processing of the CCs;
• obtaining, by the UE based on the request, one or more positioning reference signals (PRS) and one or more sounding reference signals (SRSs) of the one or more CCs;
• determining, by the UE, the PMs or the one or more RSTDs based on a respective PM for a certain CC of the CCs for which at least the PRSs and the SRSs are obtained, or on a respective RSTD of a certain CC of the CCs for which at least the PRSs and the SRSs are obtained;
• determining, by the UE, the CC ranking indicative of a weighting of the CCs based on the PRSs and the SRSs;
• determining, by the UE, the combined CAE based on the following:
• the PRSs and the SRSs;
• the CC ranking, the transmit error, and the receive error of respective CCs;
• and on the weighting of a respective CC of the CCs and the PMs or RSTDs;
• and
• providing, by the UE, the determined combined CAE to a second apparatus for determining a position of the apparatus based on the combined CAE, the second apparatus being a location management function (LMF) of a base station.
