`
` THE ’357 PATENT
` Brief Description
`The ’357 patent relates to “the transmission of system information to user
`
`equipment (UE)...by radio base stations in a wireless communication network
`
`configured according to 3GPP E-UTRA...standards, also referred to as 3GPP
`
`LTE.”1 APPLE-1001, 1:7-14. The ’357 patent acknowledges that, in LTE, the
`
`dynamic part of the system information can be transmitted using the Downlink
`
`Shared Channel (DL-SCH) and should be repeated regularly. APPLE-1001, 2:9-
`
`35; APPLE-1003, ¶28. In LTE, the dynamic part of the system information is
`
`divided into “scheduling units [(SU)], also referred to as System Information
`
`Messages.” APPLE-1001, 2:25-27.
`
`The ’357 patent describes transmitting system information with specific
`
`
`1 The term “LTE” is used in reference to the patent and prior-art disclosures as of
`
`the Critical Date, and no comment is being made as to the applicability of a
`
`particular technology or feature to the current LTE standard.

`
`RNTIs (Radio Network Temporary Identifiers) indicating the presence of system
`
`information in a subframe. APPLE-1001, 2:39-47; APPLE-1003, ¶29.
`
`The ’357 patent acknowledges that, in LTE, “Layer 1/Layer 2 (Ll/L2)
`
`control signaling, also known as the Physical Downlink Control Channel
`
`(PDCCH), is transmitted at the beginning of each subframe...to inform a UE about
`
`various items” and “includes the RNTI...associated with the UE for which the DL-
`
`SCH carries data in the given subframe.” APPLE-1001, 1:32-41; APPLE-1003,
`
`¶30.
`
`In the ’357 patent, “the transmission of system information is carried out
`
`similar to the transmission of user data on DL-SCH” according to the LTE
`
`standard, but “[i]nstead of using an RNTI of a specific UE..., a specific System-
`
`Information RNTI (SI-RNTI), indicating that system information to be read by all
`
`UEs...is being transmitted, is included in the corresponding L1/L2 control
`
`signaling.” APPLE-1001, 4:14-18; APPLE-1003, ¶31.
`
`
`Summary of the Prosecution History
`To distinguish the claims from R2-072205 during prosecution, applicant
`
`argued that “SUs are not ‘time windows’,” but rather “one of skill in the art would
`
`understand that a subframe might be considered a time window (generically), or a
`
`collection of subframes (e.g., a frame) might be considered a time window.”
`
`APPLE-1002, 102, 145. Applicant also distinguished the claimed indicator from

`IPR of U.S. Patent No. 8,995,357
`
`
`R2-072205’s value tag, arguing that “Value tags are carried on the BCH, ‘in a
`
`System Information Block called the Master Information Block (MIB),’” not “in
`
`each relevant subframe,” and that R2-072205’s “‘value tag’…is not ‘an indication
`
`of the presence of system information.’” APPLE-1002, 106, 150, 153, 192-194,
`
`197, 232-233, 235; APPLE-1003, ¶¶32-33.
`
`The examiner issued a notice of allowance after applicant amended claims to
`
`include “wherein the wireless communication network is configured for operation
`
`in accordance with 3GPP E-UTRA standards and wherein the indicator is a System
`
`information Radio Network Temporary Identifier (SI-RNTI).” APPLE-1002, 34-
`
`32, 24-30; APPLE-1003, ¶¶34-35.
`
` Level of Ordinary Skill in the Art
`For purposes of this IPR, Petitioner submits that a person of ordinary skill in
`
`the art at the time of the alleged invention (a “POSITA”) would have had a
`
`Bachelor’s degree in electrical engineering, computer engineering, computer
`
`science, or a related field, and 3-5 years of experience in the design or
`
`development of wireless communication systems, or the equivalent. APPLE-1003,
`
`¶24. Additional graduate education could substitute for professional experience, or
`
`significant experience in the field could substitute for formal education. Id.

`
` THE CHALLENGED CLAIMS ARE UNPATENTABLE
` GROUND 1A: Claims 1-2, 9-10, 22, and 24 are obvious
`based on Lee-746, Lee-668, and R2-072183
`1. Overview of Lee-746
`Lee-746 describes “a method of transmitting/receiving LTE system
`
`information in a wireless communication system.” APPLE-1004, [0002]. In Lee-
`
`746, “the system information may be grouped in primary system information and
`
`secondary system information.” APPLE-1004, [0038]. “The secondary system
`
`information may be transmitted on a transport channel with flexible scheduling,
`
`such as DL-SCH.” APPLE-1004, [0039], [0044], [0047]; APPLE-1003, ¶¶36-37.
`
`“The system information may be organized in SIBs (system information blocks), a
`
`MIB (Master information block) and scheduling blocks.” APPLE-1004, [0027].

`

`
`
`
`
`Attorney Docket No. 50095-0060IP1
`IPR of U.S. Patent No. 8,995,357
`
`
`“The MIB...may give or provide timing information of the scheduling blocks and
`
`the different SIBs.” Id. An “eNB can schedule SIBs (i.e., SIBs on SCH) within a
`
`specific Transmission Time Intervals (TTI) indicated by the MIB,” and “control
`
`information of the TTI may indicate existence of a SIB in the TTI and may
`
`schedule a time or frequency of the SIB.” APPLE-1004, [0043]; APPLE-1003,
`
`¶¶38-39.
`
`2. Overview of Lee-668
`Lee-668 describes processing control information in a wireless
`
`communication system. APPLE-1006, Abstract; APPLE-1003, ¶¶40-41. Lee-668
`
`explains that “[i]n the related art,...system information is always fixed or non-
`
`flexible….” APPLE-1006, [0029], [0036]. In contrast, Lee-668 “allow[s] at least
`
`some portions of the system information to be dynamically (or flexibly) changed.”
`
`APPLE-1006, [0030], [0036].
`
`Lee-668 “divides (or separates or distinguishes) the system information into
`
`primary system information (e.g.,...MIB) and non-primary (or secondary) system
`
`information (e.g.,...SIB).” APPLE-1006, [0037]. In Lee-668, “the SIB is
`
`transmitted in a dynamic manner (e.g., via a downlink SCH for dynamic manner
`
`transmission)” in which “different frequency ranges and time durations can be
`
`used.” APPLE-1006, [0038], [0030], [0036], [0069]-[0075]; APPLE-1003, ¶¶42-
`
`45.

`
`
`3. Overview of R2-072183
`R2-072183 relates to “provisioning of system information in LTE.”
`
`APPLE-1005, 1. R2-072183 discloses that “system information is provided on
`
`BCCH [(Broadcast Control Channel)] over DL-SCH” with “the information...
`
`structured in...(SU[s]), where an SU consists of one or more...(SIBs).” Id. In R2-
`
`072183, one complete SU can be sent in one subframe, or an SU can be segmented
`
`with a segment sent in a subframe and different segments sent in consecutive
`
`subframes. Id.; APPLE-1003, ¶¶46-47. For transmission of the system
`
`information on BCCH over DL-SCH, a PDCCH is allocated per SU or SU-
`
`segment in a subframe and includes a BCCH RNTI. Id.
`
`4. Combination of Lee-746, Lee-668, and R2-072183
`As explained in more detail below, a POSITA would have found it obvious
`
`to complement Lee-746’s system for transmitting/receiving SIBs with Lee-668’s
`
`teaching of transmitting an SIB in a dynamic manner by dynamically selecting the
`
`frequency range and time duration (subframes) used for carrying the SIB (system
`
`information) and with R2-072183’s teaching of including a BCCH RNTI in the
`
`downlink control channel allocated to each subframe carrying system information.
`
`APPLE-1006, [0038], [0030], [0036], [0069]-[0075]; APPLE-1005, 1; APPLE-
`
`1003, ¶¶63-87. More specifically, and consistent with Lee-746, Lee-668, and R2-
`
`072183’s teachings, Lee-668 would have motivated a POSITA to implement the
`

`

`
`
`
`
`Attorney Docket No. 50095-0060IP1
`IPR of U.S. Patent No. 8,995,357
`
`
`Lee-746 system to also transmit an SIB in a dynamic manner by dynamically
`
`selecting the frequency range and time duration (subframes) used for carrying the
`
`SIB (system information), and R2-072183 would have motivated a POSITA to
`
`implement the Lee-746 system to also include a BCCH RNTI as the information in
`
`the downlink control channel allocated to each subframe of the TTI carrying
`
`system information, to indicate the existence of system information in the
`
`subframe. Id.
`
` Combination of Lee-746 and Lee-668
`Lee-746 describes a “more flexible size of the SIB” and “more flexibility of
`
`SCH scheduling.” APPLE-1004, [0043], [0047], [0003]; APPLE-1003, ¶64. Lee-
`
`668 describes that “the SIB is transmitted in a dynamic manner (e.g., via a
`
`downlink SCH for dynamic manner transmission)” in which “different frequency
`
`ranges and time durations can be used.” APPLE-1006, [0038], [0030], [0036],
`
`[0069]-[0075]. To provide for dynamic transmission of SIBs, Lee-668 describes
`
`that “[f]or each frame, the MIB contains information about where each SIB is
`
`located” (particular frequency range and particular time duration) “to allow the
`
`terminal (UE) to properly read the appropriate SIBs.” APPLE-1006, [0039]. As
`
`shown in FIG. 8 below, a MIB, which provides scheduling information related to
`
`which frequency and what time is
