Response to Remarks/Comments
Prior Art Rejection(s)
The status of the claim(s) in the Non-Final Rejection mailed in light of the prior art of record was as follows: Claim(s) 1, 3, 4, 5, 9, 12, 14, 15, 16, 20, 23, 25, 26, 27, 29, were rejected under 35 U.S.C. 103 as being unpatentable over LIU (US 20220287011 A1) in view of Angelopoulos (US 20170222753 A1). Claim(s) 2, 7, 8, 13, 18, 19, 24, and 30 were rejected under 35 U.S.C. 103 as being unpatentable over LIU (US 20220287011 A1) in view of Angelopoulos (US 20170222753 A1) in view of VAIDYA (US 20200044792 A1). Claim(s) 6, 17, and 28, were rejected under 35 U.S.C. 103 as being unpatentable over LIU (US 20220287011 A1) in view of Angelopoulos (US 20170222753 A1) in view of YANG (“US 11304190 B2”). Claim 10-11 and 21-22 were objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims.
Responsive to the prior art rejection(s) claim(s) have further limited the recited “feedback information” such that the feedback information is now “hybrid automatic repeat/request acknowledgement information” (See independent claim(s) 1, 12, 23 and 29). Applicants further argue that the prior art of record, LIU (US 20220287011 A1) in view of Angelopoulos (US 20170222753 A1) fail to render obvious the independent claim(s) in light of the claim amendments, because while Angelopoulos teaching of rateless coding not requiring feedback information, Angelopoulos is silent on hybrid automatic repeat/request acknowledgement.
“However, Angelopoulos's discussion of rateless coding schemes that do not require feedback pertaining to channel estimation and rate adaptation fails to teach or suggest "wherein hybrid automatic repeat/request acknowledgment information for the data transmission is disabled based at least in part on the data transmission utilizing the rateless coding scheme," as recited in amended independent claim 1. In particular, Angelopoulos merely describes an inherent property of rateless coding, which is that rate adaptation feedback is not needed because the coding is "rateless". But Angelopoulos fails to describe any implications that rateless coding schemes have for "hybrid automatic repeat/request acknowledgment information," as claimed. For example, Angelopoulos fails to provide any technical connection between rateless coding schemes and "hybrid automatic repeat/request acknowledgment information," let alone that "hybrid automatic repeat/request acknowledgment information for the data transmission is disabled based at least in part on the data transmission utilizing the rateless coding scheme," as recited in amended independent claim 1. Indeed, Angelopoulos provides no technical connection between the elimination of feedback for channel estimation/rate selection and any impact on "hybrid automatic repeat/request acknowledgment information for the data transmission." Thus, Angelopoulos does not teach or suggest all the features as recited in amended independent claim 1.”
Applicants additionally argue that LIU’s teaching disabling HARQ based on DCI fields doesn’t teach or suggest a feature for “…hybrid automatic repeat/request acknowledgement information for the data transmission is disabled based at least in part on the data transmission utilizing the rateless coding scheme...”
“However, disabling HARQ processes based on DCI fields does not teach or suggest that "hybrid automatic repeat/request acknowledgment information for the data transmission is disabled based at least in part on the data transmission utilizing the rateless coding scheme," as recited in amended independent claim 1.”
In response to Applicants argument that LIU’s teaching disabling HARQ based on DCI fields doesn’t teach or suggest a feature for “…hybrid automatic repeat/request acknowledgement information for the data transmission is disabled based at least in part on the data transmission utilizing the rateless coding scheme...” and that Angelopoulos is silent on hybrid automatic repeat/request acknowledgement, Applicants are reminded that In response to applicant's arguments against the references individually, one cannot show nonobviousness by attacking references individually where the rejections are based on combinations of references. See In re Keller, 642 F.2d 413, 208 USPQ 871 (CCPA 1981); In re Merck & Co., 800 F.2d 1091, 231 USPQ 375 (Fed. Cir. 1986). Thus, even in a case where Angelopoulos is silent on hybrid automatic repeat/request acknowledgement, Angelopoulos teaching of rateless coding not requiring feedback, was introduced to order to motivate the modifying LIU’s transmission feature to use rateless coding and to disable feedback information (i.e. HARQ of LIU) when rateless coding is used. This modification would provide a benefit of addressing problems caused by rapid fluctuations in the quality of a wireless communication channel, according to Angelopoulos ([Par. 8]). Furthermore, Angelopoulos does recognize acknowledgement information as feedback, refer to the following:
“[0105] The first layered scheme estimates the channel quality using feedback information contained in the acknowledgment frames and adjusts the transmission rate every fifth transmitted packet based on a lookup table rate adaptation mechanism. We call this scheme “baseline,” as opposed to the second scheme which we call it “genie-aided” scheme. The rate selection in the genie-aided scheme is performed by an ideal genie having access to perfect and instantaneous CSI, always making the optimal, per-packet rate selection. Both schemes use a lossy ECG compression scheme of a wavelet transformation with adaptive coefficients thresholding. A BCH code supporting two coding rates of (63,30) and (63,51) is used as the channel coding method, and QAM schemes of three constellation orders (QAM-2.sup.2, QAM-2.sup.4 and QAM-2.sup.6) are used for signal modulation.”
Thus, for the reasons explained Applicants arguments have been found unpersuasive.

Claim(s) 1, 3, 4, 5, 9, 12, 14, 15, 16, 20, 23, 25, 26, 27, 29, is/are rejected under 35 U.S.C. 103 as being unpatentable over LIU (US 20220287011 A1) in view of Angelopoulos (US 20170222753 A1).
In regards to claim 1, LIU (US 20220287011 A1) teaches a method for wireless communication at a user equipment (UE), comprising ([0032 - 0034] teaches a UE, “[0032]…electronic device…[0034] The electronic device 100 may be arranged at a side of the UE”): receiving a downlink control information comprising a grant scheduling a data transmission for the UE, ([0032] teaches receiving downlink control information, “…electronic device…includes an acquiring unit…acquiring unit…is configured to acquire Downlink Control Information (DCI) from a base station…”. [0043] teaches the DCI comprising a grant scheduling a data transmission for the UE, “…in DCI for scheduling the first PDSCH….”); wherein hybrid automatic repeat/request acknowledgement information for the data transmission is disabled based at least in part on ([0032] teaches determining to disable feedback information the data transmission based at least in part on the DCI, “electronic device…includes…a determining unit…the determining unit…is configured to determine, at least based on a first particular field of the DCI, whether a feedback mechanism of Hybrid Automatic Repeat Request (HARQ) process is disabled…”); transmitting or monitoring for the data transmission according to the downlink control information (teaches performing or monitoring for data transmission according to the DCI, “[0038] It should be noted that when the HARQ feedback mechanism is disabled, the possibility of performing blind transmission using the HARQ is not ruled out to ensure the reliability of the system. Blind transmission using the HARQ refers to that a transmitter transmits the same data repeatedly for multiple times in a certain time period, without waiting for feedback from a receiver. The receiver soft merges the data packets received for multiple times during the time period without checking and feeding back for each data packet.”, [0032] teaches performing or monitoring for the feedback information for the data transmission according to the determining, “…In a case of determining that the feedback mechanism of the HARQ process is disabled, a check result for a data packet is not fed back to the base station,”).
LIU differs from claim 1, in that LIU is silent on the data transmission utilizing a rateless coding scheme and wherein hybrid automatic repeat/request acknowledgement for the data transmission is disabled based at least in part on the data transmission utilizing the rateless coding scheme. Despite these differences similar features have been seen in other prior art involving wireless communication systems. Angelopoulos (US 20170222753 A1) teaches the use of rateless coding for wireless communication without feedback in order to address the problem of rapid fluctuations in the quality of a wireless medium (“[0008] Rapid fluctuations in the quality of a wireless medium (e.g., caused by such factors as environmental mobility and external interference) often deteriorate performance of channel coding schemes with fixed coding rate, resulting in a behavior usually known as “threshold effect.” Channel estimation and rate adaptation techniques partially address this behavior by adjusting transmission parameters depending on the experienced channel, but they are limited by the fundamental trade-off of channel quality tracking versus transmission signal energy. In some instances, rateless coding schemes have been proposed as an alternative approach without requiring feedback information, while in other proposals some cross-layer schemes provide a wider range of operational channel SNR.”).
Thus based upon the teachings of Angelopoulos (US 20170222753 A1) it would have been obvious to a person of ordinary skill in the art before the effective filing date of the claimed invention to modify the wireless communication feature of LIU by adopting the use of rateless coding and taking advantage of the ability to disable the feedback information (disabling HARQ), to thus arrive at claim 1, in order to address problems caused by rapid fluctuations in the quality of a wireless communication channel.

LIU differs from claim 23, in that LIU is silent on the data transmission utilizing a rateless coding scheme and wherein the hybrid automatic repeat/request acknowledgement information for the data transmission is disabled based at least in part on the data transmission utilizing the rateless coding scheme. Despite these differences similar features have been seen in other prior art involving wireless communication systems. Angelopoulos (US 20170222753 A1) teaches the use of rate coding for wireless communication without feedback in order to address the problem of rapid fluctuations in the quality of a wireless medium (“[0008] Rapid fluctuations in the quality of a wireless medium (e.g., caused by such factors as environmental mobility and external interference) often deteriorate performance of channel coding schemes with fixed coding rate, resulting in a behavior usually known as “threshold effect.” Channel estimation and rate adaptation techniques partially address this behavior by adjusting transmission parameters depending on the experienced channel, but they are limited by the fundamental trade-off of channel quality tracking versus transmission signal energy.

Thus based upon the teachings of Angelopoulos (US 20170222753 A1) it would have been obvious to a person of ordinary skill in the art before the effective filing date of the claimed invention to modify the wireless communication feature of LIU by adopting the use of rateless coding and taking advantage of the ability to disable the feedback information (disabling HARQ), to thus arrive at claim 23, in order to address problems caused by rapid fluctuations in the quality of a wireless communication channel.

LIU differs from claim 29, in that LIU is silent on the data transmission utilizing a rateless coding scheme and the hybrid automatic repeat/request acknowledgement for the data transmission being disabled based at least in part on the rateless coding scheme. Despite these differences similar features have been seen in other prior art involving wireless communication systems.
