Regarding Claim 28, Ramachandran teaches the respective claim(s) as presented above and further teaches wherein the one or more target path reporting configuration messages configure the sensing node to obtain the one or more target path measurements during a sensing session (Ramachandran: paragraph 0114, discovery of ranging capable devices and/or during connection setup between ranging capable devices and/or exchanging messages to initiate a ranging session), wherein the sensing session is configured with one or more line of sight (LOS) paths between the sensing node and the one or more transmitting nodes (Ramachandran: paragraph 0182, UE may indicate line-of-sight connection between the UEs), one or more LOS paths between the sensing node and the one or more targets (Ramachandran: paragraph 0182, UE may indicate line-of-sight connection between the UEs), and one or more LOS paths between the one or more transmitting nodes and the one or more targets (Ramachandran: paragraph 0182, line-of-sight connection between the UEs), wherein one or more positions of the one or more transmitting nodes are known for the sensing session (Ramachandran: paragraph 0119, anchor UE may have a known/fixed position), and wherein a position of the sensing node is known for the sensing session (Ramachandran: paragraphs 0121 & 0174, positioning of device UE).
Regarding Claim 29, Ramachandran teaches the respective claim(s) as presented above and further teaches wherein the determining of the one or more positions of the one or more targets using the one or more target path measurement reports corresponding to the one or more target paths further comprise:
determining the one or more positions of the one or more targets using the one or more target path measurement reports, the one or more positions of the one or more transmitting nodes, and the position of the sensing node (Ramachandran: paragraphs 0177-0179, report measurement/ranging results to determine target position).
Regarding Claim 30, Ramachandran teaches the respective claim(s) as presented above and further teaches wherein for a first target path of the one or more target paths, the one or more target path measurements comprise a difference between a time a first reference signal of the first target path arrives at the sensing node and a time a second reference signal of the one or more LOS paths between the sensing node and the one or more transmitting nodes arrives at the sensing node (Ramachandran: paragraphs 0087-0089, time difference of arrival corresponding to a difference in time stamps at which a data packet is received by a number of receivers).
Conclusion
The prior art made of record and not relied upon is considered pertinent to applicant's disclosure.
Shim et al. (US 2025/0301449 A1) teaches a method comprising the steps of: reporting capability information about the terminal related to location measurement; receiving configuration information for the location measurement; performing a measurement on a received reference signal on the basis of the configuration information; and reporting a measurement result for the reference signal (paragraph 0007).
Wang et al. (US 2025/0267620 A1) teaches multiple paths for transmitting a reference signal including a line of sigh (LOS) path and a no-line of sight (NLOS) path (paragraphs 0102-0104).
Chen et al. (US 2025/0212160 A1) teaches a network entity requesting positioning capabilities of a terminal device (paragraphs 0087-0092).
