CTNF 18/766,296 CTNF 79873 Notice of Pre-AIA or AIA Status 07-03-fti AIA The present application is being examined under the pre-AIA first to invent provisions. DETAILED ACTION Claim Objections 07-29-01 AIA Claim 31 is objected to because of the following informalities: Regarding claim 31, line 1, the claim recites wireless communication comprising . . . which should be corrected to – wireless communication system comprising –. Appropriate correction is required. Claim Rejections - 35 USC § 112 07-30-02 AIA The following is a quotation of 35 U.S.C. 112(b): (b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention. The following is a quotation of 35 U.S.C. 112 (pre-AIA), second paragraph: The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention. 07-34-01 AIA Claim s 6, 8, 9, 11, 21, 23, 24, 26, and 31-45 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor, or for pre-AIA the applicant regards as the invention. Regarding claims 6, 21, and 36, for example see claim 6, the claims recite interval n + K ; however, neither the dependent claim nor the parent claim specifies the value of “K” (see line 6). Therefore, the term “K” lacks proper antecedent basis and the value of K is unclear from the context of the claim. Appropriate clarification and correction is required. Regarding claims 8, 9, 23, 24, 38, and 39, for example see claim 8, the claims recite computing MMSE (b) (see line 5); however, the value to which "(b)" refers is unclear from the context of the claim. Further, it is unclear what value is being utilized to calculate the minimum mean square error as the claim does not define the value of "b". Appropriate clarification and correction is required. Regarding claims 11, 26, and 41, the claim recites N best-UL UEs among N Pre per subband to produce two UE by SB tables, where the first table provides the IDS . . . an initial SB . . . a PDCCH . . . . See lines 2-4, 12, and 17, respectively. The claim does not define the terms/acronyms N best-UL UEs, N pre per subband, SB, and PDCCH. Appropriate clarification and correction is required. Regarding claim 31, line 2, the claim recites said at least one user equipment. The claim term “said at least one user equipment” lacks proper antecedent basis. Appropriate clarification and correction is required. Claim Rejections - 35 USC § 102 07-07-fti The following is a quotation of the appropriate paragraphs of pre-AIA 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – 07-12-fti 07-12 (e) the invention was described in (1) an application for patent, published under section 122(b), by another filed in the United States before the invention by the applicant for patent or (2) a patent granted on an application for patent by another filed in the United States before the invention by the applicant for patent, except that an international application filed under the treaty defined in section 351(a) shall have the effects for purposes of this subsection of an application filed in the United States only if the international application designated the United States and was published under Article 21(2) of such treaty in the English language. 07-15-03-fti Claim s 1, 2, 5, 16, 17, 20, 23-29, 31, 32, 35, 38-41, 45 and 46 are rejected under pre-AIA 35 U.S.C. 102(e) as being anticipated by Hanaki et al. (US 2011/0207467 A1), hereinafter referred to as Hanaki . Regarding claims 1, 16, 31, and 46, Hanaki discloses a base station, upper node, radio communication system and radio communication method, which comprises: each user equipment periodically measuring channel quality of communication with the base station; each user equipment periodically transmitting a channel quality indicator to the base station corresponding to a measured channel quality; the base station scheduling communication with the at least one user equipment based upon the periodically transmitted channel quality indicators of the at least one user equipment (Referring to Figures 1 and 2, the base station 100 performs allocation of radio resource and the like (base station scheduling communication with the at least one UE based upon the periodically transmitted channel quality indicators of the least one UE), the radio terminal 10 transmits uplink control data (each UE periodically transmitting a channel quality indicator to the base station corresponding to a measured channel quality) to the base station 100a through an enhanced dedicated physical control channel (E-DPCCH) or an E-DPDCH. Uplink control data includes scheduling information (UL scheduling information) which the base station 100a references in allocating radio resource. Scheduling information includes an "HLID (highest priority logical channel ID)," a "TEBS (total E-DCH buffer status)," an "HLBS (highest priority logical channel buffer status)," a "UPH (user power headroom)" and the like. Examples of uplink control data other than the scheduling information include a "happy bit," a " CQI" and the like (refer to 3GPP TS25. 321 Ver. 7.5.0 9.2.5.3 "UL Scheduling Information"). An "HLID" is an identifier for identifying a logical channel having the highest priority among logical channels transmitting uplink data. A "TEBS" is information indicating the amount of uplink data (buffer amount) stored in a transmission buffer provided to the radio terminal 10. An "HLBS" is the amount of uplink data (buffer amount) corresponding to the logical channel identified by the HLID, among the uplink data stored in the transmission buffer provided to the radio terminal 10. A "UPH" is a transmission power ratio which is a ratio of a transmission power of a DPCCH to the maximum transmission power (maximum UE transmission power). The maximum transmission power is the maximum allowable transmission power of the radio terminal 10. For example, a UPH is expressed as "maximum transmission power"/"transmission power of DPCCH." A "happy bit" is information indicating the degree of happiness, which shows whether or not an SG allocated to the radio terminal 10 is sufficient. There are two types of "happy bits" including "happy" which indicates that the SG allocated to the terminal is sufficient and "unhappy" which indicates that the SG allocated to the terminal is insufficient. Note that a "happy bit" is indicated by a single bit. A "CQI" is a reception quality value indicating a reception quality of a downlink signal (such as a CPICH; common pilot channel) that the radio terminal 10 receives from the base station 100 (each UE periodically measuring channel quality of communication with the base station, as CQI is perform periodically per the standard). See paragraphs 0037-0044.) Regarding claims 2, 17, and 32, Hanaki discloses said step of scheduling communication schedules uplink transmissions from a user equipment to the base station wherein the base station receives a channel quality indicator of each physical resource block, computes a scheduling metric for each receiver type, and limits the size of uplink allocation based upon reported headroom and buffer size (Referring to Figures 1 and 2, the base station 100 performs allocation of radio resource and the like (equivalent to a scheduling metric as the base station is responsible for scheduling/allocation), the radio terminal 10 transmits uplink control data to the base station 100a through an enhanced dedicated physical control channel (E-DPCCH) or an E-DPDCH. Uplink control data includes scheduling information (UL scheduling information) which the base station 100a references in allocating radio resource. Scheduling information includes an "HLID (highest priority logical channel ID)," a "TEBS (total E-DCH buffer status)," an "HLBS (highest priority logical channel buffer status)," a "UPH (user power headroom)" and the like. Examples of uplink control data other than the scheduling information include a "happy bit," a " CQI" (corresponding to each PRB) and the like (refer to 3GPP TS25. 321 Ver. 7.5.0 9.2.5.3 "UL Scheduling Information"). See paragraphs 0032 and 0037-0044. The radio terminal 10 has a table related to uplink data transmitted through an E-DPDCH, the table associating transmission power ratios and transmission rates (thus, limiting size of uplink allocation based on reported headroom and buffer size). A transmission power ratio is a ratio between a transmission power of an E-DPDCH and a transmission power of a DPCCH (E-DPDCH/DPCCH). A transmission rate is indicated by a TBS (transport block size).) See paragraph 0034.) Regarding claims 5, 20, and 35, Hanaki discloses said step of scheduling communication employs a minimum scheduling unit of an integer N of Physical Resource Blocks (Referring to Figures 1 and 2, the radio terminal 10 has a table related to uplink data transmitted through an E-DPDCH, the table associating transmission power ratios and transmission rates. A transmission power ratio is a ratio between a transmission power of an E-DPDCH and a transmission power of a DPCCH (E-DPDCH/DPCCH). A transmission rate is indicated by a TBS (transport block size), thus limiting to integer values for corresponding PRBs. See paragraph 0034.) Regarding claims 23-29, 38-41, and 45, Hanaki discloses said base station is further operable to pre-schedule by . . . (Note, the Examiner interprets the claim term “operable” as a system capable of being programmed to accomplish the claimed limitations. Hanaki teaches a programmable base station which is also capable of being programmed to perform the same recited claim limitations. Further, the claim does not recite an actual positive recitation but merely that the base station is “operable to” and the prior art also teaches a base station “operable to”. Referring to Figures 1 and 2) Claim Rejections - 35 USC § 103 07-20-fti The following is a quotation of pre-AIA 35 U.S.C. 103(a) which forms the basis for all obviousness rejections set forth in this Office action: (a) A patent may not be obtained though the invention is not identically disclosed or described as set forth in section 102 of this title, if the differences between the subject matter sought to be patented and the prior art are such that the subject matter as a whole would have been obvious at the time the invention was made to a person having ordinary skill in the art to which said subject matter pertains. Patentability shall not be negatived by the manner in which the invention was made. 07-21-fti Claim 3, 4, 6, 7, 18, 19, 21, 22, 33, 34, 36, 37, and 47 are rejected under pre-AIA 35 U.S.C. 103(a) as being unpatentable over Hanaki et al. (US 2011/0207467 A1), hereinafter referred to as Hanaki, in view of Ishii et al. (US 2010/0113082 A1), hereinafter referred to as Ishii . Regarding claims 3, 18, 33, and 47, Hanaki does not disclose each user equipment signaling the base station a scheduling recommendation regarding Modulation and Coding Scheme and Multiple Input, Multiple Output configuration; and the method wherein said step of scheduling communication schedules downlink transmissions from the base station to a user equipment in response to the recommendations. Ishii teaches that it is well-known in the art within the LTE system, so-called Adaptive Modulation and Coding (AMC) is applied, thereby signaling MCS and MIMO configuration and corresponding scheduling according to the adaptation; therefore, transmission formats of the shared channels may vary among different sub-frames. Herein, the transmission format includes various information items indicating such as allocation information of the resource blocks which are frequency resources, modulation scheme, payload size, HARQ (Hybrid Automatic Repeat reQuest) information such as a Redundancy version parameter, a process number and the like, the number of streams, and a Pre-coding vector, and information items of an MIMO and the like. See paragraphs 0006, 0082, and 0083. It would have been obvious to one of ordinary skill in the art at the time of the invention to modify the system of Hanaki to comply with the well-known standard of LTE of Ishii. One of ordinary skill in the art at the time of the invention would have been motivated to do so to comply with the well-known standard of LTE. In so doing, unexpected results are not achieved. Regarding claims 4, 19, and 34, Hanaki does not disclose transmitting a schedule from the base station to a user equipment via a Physical Downlink Control Channel; said step of scheduling communication with a user equipment wherein the base station adapts Physical Downlink Control Channel parameters and searches user equipment specific and common search spaces to allocate Control Channel Elements for Downlink Control Information messages. Ishii teaches in downlink communications, a Physical Downlink Shared Channel (PDSCH) that is shared among the user equipment terminals 100.sub.n and a Physical Downlink Control Channel (PDCCH) are used. In downlink, user information and transport format information of a Downlink Shared Channel, the user information and the transport information of an Uplink Shared Channel, acknowledgement information of the Uplink Shared Channel and the like are reported via the Physical Downlink Control Channel (PDCCH). User data are transmitted via the Physical Downlink Shared Channel (PDSCH). The user data are transmitted via a Downlink Shared Channel (DL-SCH) as a transport channel. See paragraphs 0081 and 0082. It would have been obvious to one of ordinary skill in the art at the time of the invention to modify the system of Hanaki to comply with the well-known standard of LTE of Ishii. One of ordinary skill in the art at the time of the invention would have been motivated to do so to comply with the well-known standard of LTE. In so doing, unexpected results are not achieved. Regarding claims 6, 21, and 36, Hanaki does not disclose said step of scheduling communication estimates for a given channel quality information available at transmission interval n and on frequency chunk b which modulation and coding scheme (MCS) out of a fixed MCS set must be assigned to a user transmitting at transmission interval n+K. Ishii teaches that it is well-known in the art within the LTE system, so-called Adaptive Modulation and Coding (AMC), assigning a MCS to a UE in an interval, is applied; therefore, transmission formats of the shared channels may vary among different sub-frames. Herein, the transmission format includes various information items indicating such as allocation information of the resource blocks which are frequency resources, modulation scheme, payload size, HARQ (Hybrid Automatic Repeat reQuest) information such as a Redundancy version parameter, a process number and the like, the number of streams, and a Pre-coding vector. See paragraphs 0006, 0082, and 0083. It would have been obvious to one of ordinary skill in the art at the time of the invention to modify the system of Hanaki to comply with the well-known standard of LTE of Ishii. One of ordinary skill in the art at the time of the invention would have been motivated to do so to comply with the well-known standard of LTE. In so doing, unexpected results are not achieved. Regarding claims 7, 22, and 37, Hanaki does not disclose said step of scheduling communication for each allocation employs a Physical Downlink Control Channel mapping function including computing a cost function for each Control Channel Element by recited equation. Ishii teaches that it is well-known in the art within the LTE system, so-called Adaptive Modulation and Coding (AMC) is applied; therefore, transmission formats of the shared channels may vary among different sub-frames. Herein, the transmission format includes various information items indicating such as allocation information of the resource blocks which are frequency resources, modulation scheme, payload size, HARQ (Hybrid Automatic Repeat reQuest) information such as a Redundancy version parameter, a process number and the like, the number of streams, and a Pre-coding vector. See paragraphs 0006, 0082, and 0083. Further, a logical channel having the Highest priority is selected from among the logical channels having transmittable data based on the selection logics described below and the process goes to step S320 in which a Scheduling Coefficient Calculation process is performed. When the logical channel having the Highest priority is selected, the logical channel in which Persistent Resource is reserved in step S338 is also treated as a target of the selection. See paragraphs 0121-0124. Note, the Examiner equates Ishii’s calculation as equivalent to the claimed function. It would have been obvious to one of ordinary skill in the art at the time of the invention to modify the system of Hanaki to comply with the well-known standard of LTE of Ishii. One of ordinary skill in the art at the time of the invention would have been motivated to do so to comply with the well-known standard of LTE. In so doing, unexpected results are not achieved . 07-21-fti Claim s 10, 25, and 40 are rejected under pre-AIA 35 U.S.C. 103(a) as being unpatentable over Hanaki et al. (US 2011/0207467 A1), hereinafter referred to as Hanaki, in view of Ishii et al. (US 2010/0113082 A1), hereinafter referred to as Ishii, in further view of Liu et al., “Improved Recursive Maximum Expansion Scheduling Algorithms for Uplink Single Carrier FDMA Operation," 2010 IEEE 71st Vehicular Technology Conference, May 2010, pp. 1-5, hereinafter referred to as Liu . Regarding claims 10, 25, and 40, Hanaki does not disclose said step of scheduling communication includes a 2-step recursive maximum expansion calculation including initial subband allocation and expansion, and subband gap filling. Liu teaches improved recursive maximum expansion scheduling algorithms for uplink single carrier FDMA systems. Single-carrier frequency division multiple access (SCFDMA) has been selected as the uplink access scheme in the UTRA Long Term Evolution (LTE) due to its low peak-to-average power ratio properties. Nevertheless, in order to achieve such a benefit, it requires a localized allocation of the resource blocks (RBs), which naturally imposes a severe constraint on the scheduler design. In this paper, two improved recursive maximum expansion scheduling algorithms for SC-FDMA are proposed. Compared with conventional recursive maximum expansion (RME) scheme in which UE can only expand the resource allocation on neighboring RBs with the highest metrics, in proposed improved recursive maximum expansion (IRME) scheme, higher degree of freedom in RB expansion is achieved by allowing RB expansion within certain ranking threshold. Moreover, to further increase the flexibility in resource allocation, multiple surviving paths are introduced in proposed improved tree-based recursive maximum expansion (ITRME) scheme. The simulation results show that, compared with conventional RME scheme, the proposed IRME scheme can exhibit the gain about 15% in terms of spectral efficiency with a linear increase of computational complexity, and the performance can be further improved to 18% with proposed ITRME scheme if further higher complexity is permitted. See abstract. It would have been obvious to one of ordinary skill in the art at the time of the invention to implement the well-known technique of recursive maximum expansion as taught by Liu in the system of Hanaki. One of ordinary skill in the art at the time of the invention would have been motivated to do so to improve scheduling and increase spectral efficiency . Double Patenting 08-33 AIA The nonstatutory double patenting rejection is based on a judicially created doctrine grounded in public policy (a policy reflected in the statute) so as to prevent the unjustified or improper timewise extension of the “right to exclude” granted by a patent and to prevent possible harassment by multiple assignees. A nonstatutory double patenting rejection is appropriate where the conflicting claims are not identical, but at least one examined application claim is not patentably distinct from the reference claim(s) because the examined application claim is either anticipated by, or would have been obvious over, the reference claim(s). See, e.g., In re Berg , 140 F.3d 1428, 46 USPQ2d 1226 (Fed. Cir. 1998); In re Goodman , 11 F.3d 1046, 29 USPQ2d 2010 (Fed. Cir. 1993); In re Longi , 759 F.2d 887, 225 USPQ 645 (Fed. Cir. 1985); In re Van Ornum , 686 F.2d 937, 214 USPQ 761 (CCPA 1982); In re Vogel , 422 F.2d 438, 164 USPQ 619 (CCPA 1970); In re Thorington , 418 F.2d 528, 163 USPQ 644 (CCPA 1969). A timely filed terminal disclaimer in compliance with 37 CFR 1.321(c) or 1.321(d) may be used to overcome an actual or provisional rejection based on nonstatutory double patenting provided the reference application or patent either is shown to be commonly owned with the examined application, or claims an invention made as a result of activities undertaken within the scope of a joint research agreement. See MPEP § 717.02 for applications subject to examination under the first inventor to file provisions of the AIA as explained in MPEP § 2159. See MPEP §§ 706.02(l)(1) - 706.02(l)(3) for applications not subject to examination under the first inventor to file provisions of the AIA. A terminal disclaimer must be signed in compliance with 37 CFR 1.321(b). The USPTO Internet website contains terminal disclaimer forms which may be used. Please visit www.uspto.gov/patent/patents-forms. The filing date of the application in which the form is filed determines what form (e.g., PTO/SB/25, PTO/SB/26, PTO/AIA/25, or PTO/AIA/26) should be used. A web-based eTerminal Disclaimer may be filled out completely online using web-screens. An eTerminal Disclaimer that meets all requirements is auto-processed and approved immediately upon submission. For more information about eTerminal Disclaimers, refer to www.uspto.gov/patents/process/file/efs/guidance/eTD-info-I.jsp. Claims 1-3, 5-18, 22-33, and 37-47 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-3 and 5-14 of U.S. Patent No. 12035347 B2; 1-15 of U.S. Patent No. 11184905 B2; claims 1-3, 5-9, and 14-16 of U.S. Patent No. 10075969 B2. Although the conflicting claims are not identical, they are not patentably distinct from each other because instant application claim is broader in every aspect than the patent claim and is therefore an obvious variant thereof.

Conclusion 07-96 AIA The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Krishnamurthy et al. (US 20130308485 A1) - The transceiver also receives a message from the first base station identifying a third set of time-frequency resources that is a subset of the first set of time-frequency resources, and estimates the channel state based on the transmission received in the third set of time-frequency resources. Heo et al. (US 20110268045 A1) - Each first ranking is at least partially determined by whether the component carrier is configured for delay-sensitive transmissions. The method includes using the at least one first ranking to select a first component carrier for transmission of uplink control information, and encoding uplink control information into the first component carrier for transmission to the base station. Cai et al. (US 20110199985 A1) - A first modulation and coding scheme (MCS) may be determined for when the base station transmits at a low power based on the received CQI. When the spectrum efficiency of the first MCS is equal to or higher than the spectrum efficiency of a pre-determined MCS, first UE may be communicated with using a low power transmission. In some cases, a physical downlink control channel (PDCCH) downlink control information (DCI) message is transmitted to the first UE to identify a power spectral density (PSD) level.
