Methods and apparatus for enabling frequency layers for positioning

A method performed by a wireless transmit/receive unit (WTRU) comprising the steps of:

• receiving configuration information from a network, the configuration information indicating a plurality of frequency layers (FLs), wherein each FL is associated with a respective set of one or more positioning reference signal (PRS) resources, wherein the configuration information indicates a respective bandwidth and respective frequency location information for each FL of the plurality of FLs;
• receiving at least a first PRS associated with a first set of one or more PRS resources corresponding to a first FL of the plurality of FLs and a second PRS associated with a second set of one or more PRS resources corresponding to a second FL of the plurality of FLs;
• determining that a repetition factor and a comb factor are common for the first set of one or more PRS resources corresponding to the first FL and the second set of one or more PRS resources corresponding to the second FL;
• determining a plurality of measurement reporting values based on at least the first PRS associated with the first set of one or more PRS resources corresponding to the first FL of the plurality of FLs and the second PRS associated with the second set of one or more PRS resources corresponding to the second FL of the plurality of FLs, wherein the plurality of measurement reporting values corresponds to at least a first measurement reporting value indicating an aggregate reference signal received power measurement value associated with at least the first and second FLs and a second measurement reporting value indicating an aggregate reference signal time delay measurement value associated with at least the first and second FLs;
• and
• sending a measurement report comprising the first and second measurement reporting values and indications of at least the first and second FLs.
