Position measurement in presence of MBSFN signals

A user equipment (UE), for performing position measurement in a wireless communication network, the UE comprising:

• memory;
• a wireless communication interface;
• and
• a processing unit, communicatively coupled to the memory and the wireless communication interface, the processing unit configured to:
• receive assistance data from a location server, wherein the assistance data identify a plurality of candidate cells with which the UE can measure one or more position reference signals (PRS) to support a position measurement operation of the UE;
• classify the plurality of candidate cells into a first group of candidate cells and a second group of candidate cells, wherein the classification is based on whether a candidate cell transmits PRS symbols in one or more multimedia broadcast single frequency network (MBSFN) subframes in a positioning occasion, and based on a cyclic prefix (CP) length of the PRS symbols being transmitted by the candidate cell in the positioning occasion;
• select, based on one or more predetermined criteria, one of the first group or the second group of candidate cells to measure the one or more PRS in the positioning occasion;
• and
• measure the one or more PRS from the selected one of the first group or the second group of candidate cells in the positioning occasion to measure PRS measurements.

An apparatus being part of a user equipment (UE) for performing position measurement in a wireless communication network, comprising:

• means for receiving assistance data from a location server, wherein the assistance data identify a plurality of candidate cells with which the UE can measure one or more position reference signals (PRS) to support a position measurement operation of the UE;
• means for classifying the plurality of candidate cells into a first group of candidate cells and a second group of candidate cells, wherein the classification is based on whether a candidate cell transmits PRS symbols in one or more multimedia broadcast single frequency network (MBSFN) subframes in a positioning occasion, and based on a cyclic prefix (CP) length of the PRS symbols being transmitted by the candidate cell in the positioning occasion;
• means for selecting, based on one or more predetermined criteria, one of the first group or the second group of candidate cells to measure the one or more PRS in the positioning occasion;
• and
• means for measuring the one or more PRS from the selected one of the first group or the second group of candidate cells in the positioning occasion to measure PRS measurements.

A non-transitory computer readable comprising instructions that, when executed by a processor, cause the processor to:

• receive assistance data from a location server, wherein the assistance data identify a plurality of candidate cells with which the UE can measure one or more position reference signals (PRS) to support a position measurement operation of the UE;
• classify the plurality of candidate cells into a first group of candidate cells and a second group of candidate cells, wherein the classification is based on whether a candidate cell transmits PRS symbols in one or more multimedia broadcast single frequency network (MBSFN) subframes in a positioning occasion, and based on a cyclic prefix (CP) length of the PRS symbols being transmitted by the candidate cell in the positioning occasion;
• select, based on one or more predetermined criteria, one of the first group or the second group of candidate cells to measure the one or more PRS in the positioning occasion;
• and
• measure the one or more PRS from the selected one of the first group or the second group of candidate cells in the positioning occasion to measure PRS measurements.
