Location determination using user equipment preconfigured with positioning reference signal information

A user equipment for performing location determination comprising:

• a memory preconfigured with Positioning Reference Signal (PRS) configurations for a plurality of base stations within at least one wireless communication network;
• a cellular transceiver configured to wirelessly communicate with base stations;
• and
• at least one processor coupled to the memory and the cellular transceiver, the at least one processor configured to receive from the cellular transceiver a base station almanac transmitted by a location server, the base station almanac including position information and identification of local base stations, use the PRS configurations and information from the base station almanac to receive PRS signals from a first set of base stations with the cellular transceiver, receive cell-specific reference signals (CRS) from a second set of base stations with the cellular transceiver, and perform location determination using the PRS signals from the first set of base stations, the CRS signals from the second set of base stations.

A user equipment for performing location determination comprising:

• means for preconfiguring the user equipment with Positioning Reference Signal (PRS) configurations for a plurality of base stations within at least one wireless communication network;
• means for receiving from a location server a base station almanac including position information and identification of local base stations;
• means for using the PRS configurations a and information from the base station almanac to receive PRS signals from a first set of base stations;
• means for receiving cell-specific reference signals (CRS) from a second set of base stations;
• and
• means for performing location determination for the user equipment using the PRS signals from the first set of base stations, the CRS signals from the second set of base stations.

A non-transitory computer-readable medium for performing location determination by a user equipment, wherein the user equipment is preconfigured with Positioning Reference Signal (PRS) configurations for a plurality of base stations within at least one wireless communication network, the non-transitory computer-readable medium including program code stored thereon, comprising:

• program code for receiving from a location server a base station almanac including position information and identification of local base stations;
• program code for using the PRS configurations and information from the base station almanac to receive PRS signals from a first set of base stations;
• program code for receiving cell-specific reference signals (CRS) from a second set of base stations;
• and
• program code for performing location determination for the user equipment using the PRS signals from the first set of base stations, the CRS signals from the second set of base stations.
