`
`INTRODUCTION
`Huawei Device Co., Ltd. (“Petitioner” or “Huawei”) petitions for Inter
`
`Partes Review (“IPR”) seeking cancellation of claims 1-14 of U.S. Patent No.
`
`8,102,833 (Ex. 1001, the “’833 Patent”), assigned to Optis Cellular Technology,
`
`LLC (“Patent Owner”).
`
`The ’833 Patent discloses a “method for transmitting uplink signals, which
`
`include ACK/NACK signals, control signals other than the ACK/NACK signals,
`
`and data signals” whereby “the uplink signals can be transmitted to improve
`
`receiving reliability of signals having high priority.” Ex. 1001, Abstract.
`
`“ACK/NACK signals” are transmission acknowledge (ACK) and not
`
`acknowledged (NACK) signals which indicate the receipt status of transmissions.
`
`Ex. 1008, ¶38.
`
`Claim 1 requires a method for transmitting uplink signals in a wireless
`
`communication system by (i) serially multiplexing first control signals and data
`
`signals, (ii) mapping the multiplexed signals to a 2-dimensional resource matrix
`
`row by row, where columns of the resource matrix correspond to single carrier
`
`frequency divisional multiple access (SC-FDMA) symbols and rows of the
`
`resource matrix correspond to subcarriers, (iii) mapping ACK/NACK control
`
`signals to the columns of the resource matrix right adjacent to the columns carrying
`
`a reference signal by overwriting some of the multiplexed signals from the last row
`
`1
`
`

`

`
`
`of the resource matrix, and (iv) transmitting the multiplexed signals. Ex. 1001, cl.
`
`1.
`
`The ’833 Patent does not purport to have invented transmitting uplink
`
`signals in a wireless communication system, multiplexing first control signals and
`
`data signals, mapping the multiplexed signals to a 2-dimensional resource matrix,
`
`mapping ACK/NACK control signals to columns of the resource matrix right
`
`adjacent to the columns carrying a reference signal, or transmitting the multiplexed
`
`signals. The prosecution history indicates that the purported novel limitations of
`
`the ’833 Patent relate only to (i) placing the first control signals at a front part of
`
`the multiplexed signals and the data signals at a rear part of the multiplexed
`
`signals, (ii) mapping the multiplexed signals to a 2-dimensional resource matrix
`
`row by row, and (iii) overwriting some of the multiplexed signals with
`
`ACK/NACK signals from the last row of the resource matrix. Ex. 1002, 302.
`
`As shown below, the challenged claims are obvious in light of the
`
`combination of Papasakellariou, Cho, and Motorola. Papasakellariou discloses
`
`multiplexing ACK/NACK control signals, first control signals, and data signals,
`
`mapping the multiplexed signals to a 2-dimensional resource matrix, and
`
`transmitting the multiplexed signals. Ex. 1006, Figs. 1, 2, 6; Ex. 1007, Figs. 1, 2,
`
`5. Papasakellariou further discloses mapping ACK/NACK control signals to the
`
`columns of the resource matrix that are right adjacent to the columns that carry a
`
`2
`
`

`

`
`
`reference signal. Id., Fig. 6. Cho discloses serially multiplexing first control
`
`signals and data signals by placing first control signals at a front part of the
`
`multiplexed signals and data signals at a rear part of the multiplexed signals. Ex.
`
`1010, Figs. 3, 4, 6. Motorola discloses mapping signals to a 2-dimensional
`
`resource matrix row by row. Ex. 1011, Fig. 1. The combination of
`
`Papasakellariou, Cho, and Motorola also suggests overwriting multiplexed signals
`
`with ACK/NACK control signals from the last row of the resource matrix. Ex.
`
`1006, Fig. 6, 2:62-3:3; Ex. 1010, Figs. 3, 4, 6; Ex. 1011, Fig. 1.

`see also Ex. 1008, ¶64.
`
`The ’833 Patent describes “a method for transmitting uplink signals, which
`
`include ACK/NACK signals, control signals other than the ACK/NACK signals,
`
`and data signals.” Id., Abstract; Ex. 1008, ¶¶65-81. In a mobile communication
`
`system, a user equipment (UE), such as a mobile device, transmits “uplink signals”
`
`to a base station, and the base station transmits “downlink signals” to the UE. Ex.
`
`1008, ¶¶35-39. ACK/NACK signals are a type of control information or signals.
`
`Ex. 1001, 5:3-6. ACK signal signifies receipt of downlink data, and NACK signal
`
`signifies some type of error with received downlink data. Ex. 1008, ¶38. The ’833
`
`Patent may refer to “control information” or “control signals” as control
`
`information or control signals other than the ACK/NACK signals. See, e.g., Ex.
`
`1001, 1:40-44, 5:13-24.
`
`The ’833 Patent relates to 3rd Generation Partnership Project (3GPP) Long
`
`Term Evolution (LTE) system. Id., 1:33-35, 4:4-5, 4:9-11, 8:58-62. 3GPP stands
`
`for “3rd Generation Partnership Project.” 3GPP LTE system uses a single carrier
`
`frequency division multiplexing access (SC-FDMA) scheme for uplink

`

`
`
`transmission. SC-FDMA is closely related to orthogonal frequency division
`
`multiplexing access (OFDMA) scheme. Ex. 1008, ¶¶40-56, 67.
`
`The ’833 Patent describes transmitting information using “resource block”
`
`and “sub-frame.” Ex. 1001, 5:38-45. Each sub-frame includes two slots, and each
`
`slot includes 7 SC-FDMA symbols. Id., 5:40-45, cl. 3; Ex. 1008, ¶¶47-54, 73.
`
`Each resource block includes 12 OFDM subcarriers and 7 SC-FDMA symbols in
`
`one slot. Ex. 1001, 5:37-40; Ex. 1008, ¶¶47-54, 73. Two of the 14 SC-FDMA
`
`symbols in each sub-frame are used as reference signals, which are used to provide
`
`channel estimation for coherent demodulation of the received signal. Ex. 1001,
`
`5:40-43; Ex. 1006, 1:56-65; Ex. 1007, 7 (referring to “a sub-frame structure
`
`comprising of symbols carrying data or control signals and demodulation reference
`
`signals”); Ex. 1008, ¶¶55-56, 73.
`
`Figure 6, annotated below, illustrates a method for transmitting control
`
`information, data information, and ACK/NACK signals. Ex. 1001, 6:49-7:14.
`
`Figure 6 illustrates multiplexed signals 601 and 602, and multiplexed signals 603
`
`that is mapped to a “time-frequency region,” which is described as a “2-
`
`dimensional resource matrix” in claim 1. Id. 6:60-7:5; cl. 1; Ex. 1008, ¶¶78-79.
`
`Unlike the conventional orientation of rows and columns, in Figure 6, the
`
`orientation of “rows” is vertical and the orientation of “columns” is horizontal. Ex.
`
`1001, cl. 1 (describing that columns correspond to SC-FDMA symbols and rows
`
`8
`
`

`

`
`
`correspond to subcarriers); Ex. 1008, ¶¶78-79. The first row corresponds to the
`
`first subcarrier from the left of the matrix, and the first column corresponds to the
`
`first SC-FDMA symbol (#1) from the top of the matrix. Ex. 1008, ¶79.
`
`The embodiment disclosed in Figure 6 corresponds to claim 1 of the ’833
`
`Patent. Ex. 1008, ¶¶78-81. As shown in annotated Figure 6 above, the control
`
`information and data information are “serially multiplexed” in 601 and 602. Ex.
`
`
`
`9
`
`

`

`
`
`1001, 6:52-60, 8:36-40, 9:1-5.
`
`As also shown in annotated Figure 6 above, the control information is placed
`
`at a front part of the multiplexed signals 601 and 602 (1 through NC) and the data
`
`information is placed at a rear part of the multiplexed signals 601 and 602 (1
`
`through ND). Ex. 1001, 6:52-56; Ex. 1008, ¶78. Multiplexed signals 602
`
`“illustrates that the ACK/NACK signals are arranged by puncturing the
`
`multiplexed data.” Ex. 1001, 6:63-66 (coloring added); Ex. 1008, ¶78.
`
`The multiplexed signals, such as 602, are then mapped row by row to a
`
`resource matrix with a plurality of rows and columns (603), where rows
`
`correspond to subcarriers and columns correspond to SC-FDMA symbols. Ex.
`
`1001, 6:66-7:3, 7:6-10, 9:6-21. A POSITA would understand that mapping row by
`
`row as disclosed in claim 1 is the same as the “time-first mapping” method as
`
`disclosed in the specification “because the SC-FDMA symbols are segmented
`
`temporally,” or in other words, the SC-FDMA symbols are arranged temporally
`
`along the time axis. Ex. 1001, 5:46-52; Ex. 1008, ¶80.
`
`A number of columns in the resource matrix in Figure 6 corresponds to a
`
`number of SC-FDMA symbols within one subframe because “information is
`
`transmitted through one sub-frame.” Ex. 1001, 5:37-45. “[T]he reference signal is
`
`transmitted through a part between symbol indexes #3 and #4 and a part between
`
`symbol indexes #9 and #10.” Id. 7:2-5. The two parts correspond to “specific SC-
`
`10
`
`

`

`
`
`FDMA symbols used for a reference signal” in claim 1. Id. 9:12-16.
`
`The ACK/NACK signals (highlighted in yellow) “overwrite some of the
`
`multiplexed signals mapped to the 2-dimensional resource matrix” in columns
`
`“right adjacent to the specific SC-FDMA symbols” where the reference signal is
`
`transmitted. Id. 9:22-29. The ACK/NACK signals overwrite multiplexed signals
`
`“from the last row of the specific columns” at modulation symbols N-2, N-3, N-8,
`
`and N-9. Id.
`
`A modulation symbol is an individual unit of modulated data in the
`
`frequency / time domain. Ex. 1008, ¶52. An SC-FDMA symbol, on the other
`
`hand, includes multiple modulation symbols in all of the frequency subcarriers in
`
`one time unit. Ex. 1001, Figs. 6-9 (showing that one SC-FDMA symbol includes
`
`multiple modulation symbols in one time unit); Ex. 1008, ¶75.
`
`The term “overwrite” in the ’833 Patent means that “specific information
`
`mapped in the resource region is skipped and the corresponding region is mapped,”
`
`and that “the length of the entire information is maintained equally even after
`
`specific information is inserted.” Ex. 1001, 6:15-21; Ex. 1008, ¶¶71-72. “This
`
`overwriting procedure may be represented by puncturing.” Ex. 1001, Fig. 6
`
`(“Possible ACK/NACK Modulation Symbols Position which Punctures Data
`
`modulation symbols”) (emphasis added), 6:15-21.

`
`Prosecution History Summary of the ’833 Patent
`C.
`In an office action dated June 24, 2011, the Examiner rejected all of the
`
`pending claims in the ’833 Patent’s application over the combination of U.S.
`
`Patent Publication No. 2008/0304467 (“Papasakellariou Publication,” Ex. 1005),
`
`U.S. Patent Publication No. 2003/0185159 (“Seo,” Ex. 1014), and U.S. Patent
`
`Publication No. 2006/0098568 (“Oh,” Ex. 1015). Ex. 1002, 263-77.
`
`In an amendment, the applicant acknowledged that Figures 2 and 3 of
`
`Papasakellariou Publication disclose “multiplex[ing] data bits and CQI bits,” but
`
`stated that Papasakellariou Publication “does not teach anything about the
`
`sequence of data bit and CQI bits within the multiplexed signals.” Ex. 1002, 302.
`
`Second, the applicant stated that “[e]ven though Papasakellariou
`
`[Publication] simply mentions that the resource for transmitting multiplexed
`
`signals is 2-dimensional, Papasakellariou [Publication] does not teach the mapping
`
`scheme in view of this 2-dimensional resource matrix.” Id.
`
`Finally, the applicant stated that Papasakellariou Publication does not
`
`disclose that “the ACK/NACK control signals overwrite some of the mapped to the
`
`2-dimensional resource matrix at step (b) from the last row of the specific
`
`12
`
`

`

`
`
`columns[.]” Id. (emphasis in original).
`
`The Examiner subsequently allowed the claims. Ex. 1002, 308-16. See also
`
`Ex. 1008, ¶¶82-87.
`
`VII. Claim Construction (37 C.F.R. §42.104(b)(3))
`An unexpired claim subject to IPR is given its “broadest reasonable
`
`construction in light of the specification of the patent in which it appears.” 37
`
`C.F.R. §42.100(b); Cuozzo Speed Techs., LLC v. Lee, 136 S. Ct. 2131, 2142
`
`(2016).
`
`In the Litigation, the parties agreed upon several constructions that were
`
`adopted by the court as set forth in the table below. Ex. 1013, 12-14. Petitioner

`
`VIII. OVERVIEW OF THE PRIOR ART
`The First Wells Declaration describes the state of the art regarding generally,
`
`mobile radio communication, long term evolution (LTE), and signal processing
`
`functionalities. Ex. 1008, ¶¶35-63 (citing Exs. 1023-1026). As that discussion and
`
`15
`
`

`

`
`
`the prior art discussed below make clear, by August 2007, the purported invention
`
`of the ’833 Patent was obvious. Each applied reference pertains to transmitting
`
`uplink control signals and data signals in a wireless communication system. Id.,
`
`¶¶99-146. A POSITA would have combined their teachings using routine skill
`
`because these features were well-known in the industry. Id., ¶¶171-76, 196-99.
`
`Papasakellariou (Ex. 1006)
`A.
`Papasakellariou is directed to “multiplexing control and data information in
`
`single-carrier frequency division multiple access (SC-FDMA) communication
`
`systems,” and discloses transmitting “positive or negative acknowledgement bits
`
`(ACK or NAK, respectively) and channel quality indicator (CQI) bits together with
`
`data information bits in an SC-FDMA communications system” in connection with
`
`3GPP LTE standards. Ex. 1006, 1:15-28. The ACK/NAK bits and the CQI bits
`
`may be referred to as control information bits. Id. 1:36-38. See also Ex. 1008,
`
`¶¶99-106.
`
`Papasakellariou4 claims priority to Papasakellariou Provisional, which was
`
`filed on June 8, 2007. As shown in Section IX below, Papasakellariou is prior art
`
`
`
` 4
`
` Papasakellariou (Ex. 1006) is the issued patent that corresponds to
`
`Papasakellariou Publication (Ex. 1005), which was considered and cited by the
`
`Examiner during prosecution. Ex. 1001, cover page; Ex. 1002, 264-78.

`
`

`

`
`
`under 35 U.S.C. § 102(e) as of the date of this provisional application.
`
`Cho (Ex. 1010)
`B.
`Cho discloses multiplexing control and data signals, and transmitting the
`
`multiplexed control and data signals for uplink communication in a Localized
`
`Frequency Division Multiple Access (LFDMA) system. Ex. 1010, ¶[0068]; Ex.
`
`1008, ¶¶129-139. Both the ’833 Patent and Papasakellariou disclose using a
`
`LFDMA system. Ex. 1001, 2:20-22; Ex. 1006, 2:27-28; Ex. 1008, ¶134.
`
`The Examiner did not cite to or otherwise rely on Cho in any office action.
