Systems and methods for positioning with channel measurements

An entity in a wireless network configured to support position determination comprising:

• an external interface configured to communicate with entities in the wireless network;
• at least one memory;
• and
• at least one processor coupled to the external interface and the at least one memory, the at least one processor configured to:
• obtain a plurality of channel measurements for at least one Wireless Access Point (WAP), wherein the plurality of channel measurements include Line of Sight (LOS) signal measurements and Non-LOS (NLOS) signal measurements of the at least one WAP;
• determine, based on WAP almanac information and the plurality of channel measurements for the at least one WAP, at least one corresponding set of channel parameters, wherein the channel parameters are indicative of positions of a plurality of signal sources relative to a previous position information of a User Equipment (UE), wherein one or more signal sources in the plurality of signal sources is a virtual signal source associated with the NLOS signal measurements;
• associate the plurality of signal sources with corresponding channel parameters in the at least one corresponding set of channel parameters;
• determine, based on the previous position information of the UE and the association of the plurality of signal sources with the corresponding channel parameters, a current position information of the UE;
• and
• update the WAP almanac information based on position information of at least one signal source in the plurality of signal sources, a signal blockage probability of the at least one signal source, and an antenna geometry for the at least one signal source.

An entity in a wireless network configured to support position determination comprising:

• means for obtaining a plurality of channel measurements for at least one Wireless Access Point (WAP), wherein the plurality of channel measurements include Line of Sight (LOS) signal measurements and Non-LOS (NLOS) signal measurements of the at least one WAP;
• means for determining, based on WAP almanac information and the plurality of channel measurements for the at least one WAP, at least one corresponding set of channel parameters, wherein the channel parameters are indicative of positions of a plurality of signal sources relative to a previous position information of a User Equipment (UE), wherein one or more signal sources in the plurality of signal sources is a virtual signal source associated with the NLOS signal measurements;
• means for associating the plurality of signal sources with corresponding channel parameters in the at least one corresponding set of channel parameters;
• means for determining, based on the previous position information of the UE and the association of the plurality of signal sources with the corresponding channel parameters, a current position information of the UE;
• and
• means for updating the WAP almanac information based on position information of at least one signal source in the plurality of signal sources, a signal blockage probability of the at least one signal source, and an antenna geometry for the at least one signal source.

A non-transitory storage medium including program code stored thereon, the program code is operable to configure at least one processor in an entity in a wireless network to support position determination, the program code comprising instructions to:

• obtain a plurality of channel measurements for at least one Wireless Access Point (WAP), wherein the plurality of channel measurements include Line of Sight (LOS) signal measurements and Non-LOS (NLOS) signal measurements of the at least one WAP;
• determine, based on WAP almanac information and the plurality of channel measurements for the at least one WAP, at least one corresponding set of channel parameters, wherein the channel parameters are indicative of positions of a plurality of signal sources relative to a previous position information of a User Equipment (UE), wherein one or more signal sources in the plurality of signal sources is a virtual signal source associated with the NLOS signal measurements;
• associate the plurality of signal sources with corresponding channel parameters in the at least one corresponding set of channel parameters;
• determine, based on the previous position information of the UE and the association of the plurality of signal sources with the corresponding channel parameters, a current position information of the UE;
• and
• update the WAP almanac information based on position information of at least one signal source in the plurality of signal sources, a signal blockage probability of the at least one signal source, and an antenna geometry for the at least one signal source.
