Claim Rejections - 35 USC § 103
The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action:
A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made.
Claims 9, 10 and 19 are rejected under 35 U.S.C. 103 as being unpatentable over Khoryaev in view of Shreevastav et al. (US-12,381,686 hereinafter, Shreevastav).
Regarding claim 9, Khoryaev teaches the limitations of claim 1 above, but differs from the claimed invention by not explicitly reciting wherein before sending the first request message to the network side, the method further comprises:
receiving an UL positioning trigger condition sent by an LMF;
wherein, the UL positioning trigger condition comprises one or more of following:
a time instant at which positioning is triggered;
a period that positioning is triggered;
a quantity of times for which positioning is triggered; or
an event that triggers positioning.
In an analogous art, Shreevastav teaches a method and system for signaling support in a wireless network (Abstract) that includes before sending the first request message to the network side (Fig. 2B [7]), the method further comprises:
receiving an UL positioning trigger condition sent by an LMF; (Fig. 2B [4, 5 & 6])
wherein, the UL positioning trigger condition comprises one or more of following:
a time instant at which positioning is triggered; (Col. 8 line 66 through Col. 9 line 22)
a period that positioning is triggered;
a quantity of times for which positioning is triggered; or
an event that triggers positioning.
Before the effective filing date of the invention, it would have been obvious to one of ordinary skill in the art to be motivated to implement the invention of Khoryaev after modifying it to incorporate the ability to send a UL positioning trigger condition of Shreevastav since it enables the network to know when to listen for UL SRS signals. (Shreevastav Col. 9 lines 18-22)
Regarding claim 10, Khoryaev teaches the limitations of claim 1 above including the ability to receive information from a base station via RRC messages (Fig. 3 [308]), but differs from the claimed invention by not explicitly reciting wherein before sending the first request message to the network side, the method further comprises:
receiving a Radio Resource Control (RRC) message sent by a base station, wherein the RRC message carries one or more of following:
configuration information of the UL positioning reference signal that is pre-configured for the terminal;
configuration information of the activation request signal that is pre-configured for the terminal and used for activating the UL positioning reference signal; or
a pre-configured preamble that is dedicated to activating the UL positioning reference signal.
In an analogous art, Shreevastav teaches a method and system for signaling support in a wireless network (Abstract) that includes before sending the first request message to the network side (Fig. 2B [7]), the method further comprises:
receiving a Radio Resource Control (RRC) message sent by a base station (Col. 8 lines 11-16), wherein the RRC message carries one or more of following:
configuration information of the UL positioning reference signal that is pre-configured for the terminal; (Col. 8 lines 20-25 “the UE may be configured to start transmitting an uplink reference signal before a BS sends the UL configuration to LMF, for example, as soon as the UE has applied the UL signal configuration. A BS may control the time instance when UE should start transmitting UL reference signals (e.g. SRS)”)
configuration information of the activation request signal that is pre-configured for the terminal and used for activating the UL positioning reference signal; or
a pre-configured preamble that is dedicated to activating the UL positioning reference signal.
Before the effective filing date of the invention, it would have been obvious to one of ordinary skill in the art to be motivated to implement the invention of Khoryaev after modifying it to incorporate the ability to send configuration information for UL positioning reference signal of Shreevastav since it enables the network to know when to listen for UL SRS signals. (Shreevastav Col. 9 lines 18-22)
Regarding claim 19, the limitations of claim 19 are rejected as being the same reasons set forth above in claim 10.

/Matthew C Sams/Primary Examiner, Art Unit 2646
1 Under the broadest reasonable interpretation standard for conditional “if language” or “when language”, the condition does not occur and the step or function claimed would never be realized, hence the broadest reasonable interpretation of the claim does not require performing the step or function. See Ex parte Katz, 2011 WL 514314, at 4-5 (BPAI Jan. 27, 2011,2011 WL 1211248 at 2 (BPAI Mar. 25, 2011); see also In re Johnston, 435 f.3d 1381, 1384 (Fed. Cir. 2006)("optional elements do not narrow the claim because they can always be omitted”). If conditions are not limitations against which prior art must be found because the step or function only occurs “if the answer is positive” or “when the answer is positive”. Under the broadest scenario, the steps or functions dependent on the “if condition” or “when condition” would not be invoked, and such, the Examiner is not required to find these limitations in the prior art in order to render the claim anticipated. See In re Am. Acad. Of Sci. Tech Ctr., 367 f.3d 1359, 1359 (Fed. Cir. 2004).
