DETAILED ACTION
Applicant's submission filed on 17 September 2025 has been entered. Claims 1-5, 7, 9-11, and 13 are currently amended; no claim is cancelled; claims 6, 8, 12, and 14 are previously presented; no claims have been added. Claims 1-14 are pending and ready for examination.
Response to Arguments
Applicant’s arguments, see pages 8-11, filed 17 September 2025, with respect to “Claim Rejections” have been fully considered but they are not persuasive. Applicant argues that Samsung teaches Samsung’s DL latency is teaching a round-trip latency of the claims.
The examiner respectfully disagrees. Samsung’s DL latency is teaching the claimed air interface latency, specifically the latency of the air interface between the apparatus and the UE. The other claim elements argued were added to the claim, so those arguments are moot in view of the new grounds of rejection, but the examiner wanted to provide clarification for what Samsung is teaching versus what Samsung is not teaching.
Applicant’s arguments with respect to the claims have been considered but are moot in view of the new grounds of rejection.
Claim Objections
Claims 1-6 are objected to because of the following informalities: Claim 1 recites the limitation "…corresponding to the uplink packet" in line 8. There is insufficient antecedent basis for this limitation in the claim. The closest claim element is “an uplink data packet” in line 3. Regarding claims 2-6, these claims depend upon independent claim 1 and fail to rectify the matter. Appropriate correction is required.
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.
The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows:
1. Determining the scope and contents of the prior art.
2. Ascertaining the differences between the prior art and the claims at issue.
3. Resolving the level of ordinary skill in the pertinent art.
4. Considering objective evidence present in the application indicating obviousness or nonobviousness.
Claims 1-14 are rejected under 35 U.S.C. 103 as being unpatentable over WO 2017/034274 A1, hereafter referred Samsung, in view of Lee et al. (US 2022/0345929 A1), hereafter referred Lee, further in view of Oh et al. (US 7,260,399 B1), hereafter referred Oh. Samsung and Oh were cited by applicant’s IDS filed 27 January 2024.
Regarding claim 1, Samsung teaches a method for data transmission, comprising:
obtaining, by an access network device, an air interface latency of the downlink data packet corresponding to the uplink packet (Samsung, Fig. 5, [76]-[85]; The UE transmits (510) time DL latency report to apparatus 100 the apparatus obtains the DL latency in step 510); and
scheduling, by the access network device, the downlink data packet based on the air interface latency of the downlink data packet (Samsung, Fig. 5, [85]; the apparatus 100 on receiving (512) the latency report will evaluate the latency report and perform corrective actions).
Samsung does not expressly teach receiving, by an access network device from a terminal, an uplink data packet that carries a round-trip latency, wherein the air interface latency of the downlink data packet is calculated based on the round-trip latency.
However, Lee teaches receiving, by an access network device from a terminal, an uplink data packet that carries a round-trip latency, wherein the air interface latency of the downlink data packet is calculated based on the round-trip latency (Lee, Fig. 9 and 11, [0197]-[0216], [0222]-[0239], and [0244]; The RAN which receives a monitoring packet response from the terminal transmits an uplink monitoring packet to the PSA-UPF which includes a QOS management protocol identifier, a transmission latency of a Uu section, a local time at which the RAN received the monitoring packet request, and a local time at which the RAN received the monitoring packet response from the terminal, and the QoS monitoring protocol identifies a QoS monitoring policy that includes transmission latency information such as unidirectional or bidirectional transmission latency information between a terminal-UPF or terminal and PSA-UPF, or transmission latency information of each section of the wireless communications system illustrated in Fig. 9 and the latency times may be measured by using a round trip time).

Samsung in view of Lee does not expressly teach wherein the round-trip latency is a latency from when the terminal sends the uplink data packet to when the terminal receives a downlink data packet corresponding to the uplink data packet.
However, Oh teaches wherein the round-trip latency is a latency from when the terminal sends the uplink data packet to when the terminal receives a downlink data packet corresponding to the uplink data packet (Oh, Fig. 7, Column 11, line 46 – Column 12, line 5; sending a time-stamped query from the mobile station to the AP at block 260, where at block 262, a response to the query is received, and the round-trip delay is determined at block 264 based on the time-stamp of the query and a receipt time of the response).

Regarding claim 7, Samsung teaches a method for determining an air interface latency, comprising:
receiving, by the terminal, the downlink data packet that is sent by the access network device based on an air interface latency (Samsung, Fig. 5, [85]; the apparatus 100 on receiving (512) the latency report will evaluate the latency report and perform corrective actions).
Samsung does not expressly teach sending, by a terminal, an uplink data packet to an access network device, wherein the uplink data packet carries information about a round-trip latency and a timestamp at which the terminal sends the uplink data packet, wherein the air interface latency is calculated based on the information about the round-trip latency and the time stamp.
However, Lee teaches sending, by a terminal, an uplink data packet to an access network device, wherein the uplink data packet carries information about a round-trip latency and a timestamp at which the terminal sends the uplink data packet, wherein the air interface latency is calculated based on the information about the round-trip latency and the time stamp (Lee, Fig. 9 and 11, [0197]-[0216], [0222]-[0239], and [0244]; The RAN which receives a monitoring packet response from the terminal transmits an uplink monitoring packet to the PSA-UPF which includes a QOS management protocol identifier, a transmission latency of a Uu section, a local time at which the RAN received the monitoring packet request, and a local time at which the RAN received the monitoring packet response from the terminal, and the QoS monitoring protocol identifies a QoS monitoring policy that includes transmission latency information such as unidirectional or bidirectional transmission latency information between a terminal-UPF or terminal and PSA-UPF, or transmission latency information of each section of the wireless communications system illustrated in Fig. 9 and the latency times may be measured by using a round trip time).

Regarding claim 9, Samsung teaches a method for determining an air interface latency, comprising:
determining, by the user plane network element, a second latency, wherein the second latency is a latency from when the user plane network element sends a downlink data packet to when a terminal receives the downlink data packet (Samsung, Fig. 5, [76]-[85]; The UE transmits (510) time DL latency report to apparatus 100the apparatus obtains the DL latency in step 510).
Samsung does not expressly teach receiving, by a user plane network element from an access network device, an uplink data packet that carries a round-trip latency, wherein the second latency is calculated based on the round-trip latency; and sending, by the user plane network element, the downlink data packet to the access network device, wherein the downlink data packet carries the second latency and a timestamp at which the user plane network element sends the downlink data packet.
