Claim of US Patent No. 10,716,084

16. A method for wireless communications performed by a base station, comprising:determining resources within a narrowband region of a wider system bandwidth for transmitting one or more downlink positioning reference signals (PRSs) to one or more wireless nodes, wherein determining the resources comprises determining the resources for the one or more downlink PRSs to be repeated within the narrowband region; and
transmitting the one or more downlink PRSs using the determined resources, wherein the transmitting comprises transmitting tones of the one or more downlink PRSs repeated across at least one of:
multiple symbols within a same subframe, or
multiple consecutive subframes;
wherein each of the one or more downlink PRSs is repeated across a set of the multiple symbols within the same subframe or another subframe.
