Network assisted positioning
First Claim
1. A method for acquiring data to facilitate positioning at a mobile station (MS), the method comprising:
- receiving location based service (LBS) zone information including a size and location of an LBS zone or an LBS pilot zone for performing a positioning operation of the MS, wherein the LBS zone information indicates that the LBS zone or the LBS pilot zone is located within a slot frame corresponding to a slot frame (SF) index of 2 or 3 in every frame of a frame structure between the MS and a plurality of base stations (BSs), wherein the frame includes a plurality of slot frames;
receiving LBS pilot signals via the LBS zone from the plurality of BSs based on the LBS zone information;
performing the positioning operation for the MS based on the received LBS pilot signals,wherein the LBS pilot signals are received via a set of different time periods or different frequency regions within the slot frame corresponding to the SF index of 2 or 3.

Abstract
A method for acquiring positioning information includes receiving downlink data in a plurality of downlink slot frames, and receiving at a mobile terminal within one of the downlink slot frames, broadcasted global positioning system (GPS) orbital description data. The GPS orbital description data information relates to a first group of orbiting satellites within operable range of the base station (BS) providing the broadcasting of the GPS orbital description data. The method further includes performing GPS-based positioning for the mobile terminal based upon signaling received from a second group of a plurality of orbiting satellites in conjunction with the GPS orbital description data, such that at least one of the second group of the plurality of orbiting satellites is the same as some or all of the orbiting satellites of the first group.

5. A method for acquiring data to facilitate positioning at a mobile station (MS), the method comprising:
-
receiving, at the MS, location based service (LBS) zone information including a size and location of an LBS zone or an LBS pilot zone, wherein the LBS zone information indicates that the LBS zone or the LBS pilot zone is located within a frame comprising a plurality of portions that define at least indexes 0 to 4, wherein the LBS zone or the LBS pilot zone corresponding to an index of 2 or 3 of the frame in every frame of a frame structure between the MS and a plurality of base station (BSs); receiving, at the MS, LBS pilot signals via the LBS zone from the plurality of BSs based on the LBS zone information, wherein the LBS pilot signals are received via a set of different time periods or different frequency regions within a portion of the frame corresponding to the index of 2 or 3; and performing, at the MS, the positioning operation for the MS based on the received LBS pilot signals.
