DIFFERENTIAL POSITIONING REFERENCE SIGNAL REPORTING WITHIN CO-LOCATED CELLS

Abstract:

Disclosed are techniques for wireless positioning. In an aspect, a user equipment (UE) receives a plurality of downlink positioning reference signals (DL-PRS) transmitted by a corresponding plurality of cells, wherein the plurality of cells is grouped into one or more groups, wherein each of the one or more groups is associated with one or more attributes, and wherein each cell of each of the one or more groups has the same values of the one or more attributes, reports, to a positioning entity, at least one baseline positioning measurement for at least one representative cell of at least one group of the one or more groups based on DL-PRS transmitted by the at least one representative cell, and reports, to the positioning entity, differential positioning measurements for cells of the at least one group based on the at least one baseline positioning measurement.
