`prime number that is smaller than the desired length” (i.e., K = NFFT/IFFT, the “sec-
`
`ond length,” when Nb1 = 1 and the initial ranging “uses all sub-bands.” Ex. 1007,
`
`5:20-25 and 11:1-15). See, Ex. 1007, 8:59-9:1. See Wells Declaration, ¶ 125.
`
`Zhuang327 discloses “wherein the cyclic extension of the code sequence
`
`having the first length is performed such that a part of the code sequence having
`
`the first length, having a length corresponding to a difference between the first
`
`length and the second length, is added to either a start or an end of the code se-
`
`quence having the first length,” as recited in claim 1. Claim 7 of Zhuang327
`
`makes clear that the cyclic extension is performed such that a part of the code se-
`
`quence having the first length (“(K-NG) terms from the beginning of each GCL se-
`
`quence”) is added to an end of the code sequence having the first length: “wherein
`
`when NG is smaller than K, the corresponding set of sequences of length K is gen-
`
`erated by copying (K-NG) terms from the beginning of each GCL sequence and ap-
`
`pending them to the end.” Ex. 1007, claim 7 at 15:66-16:2. See also Petitioner-FIG.

`
`Zhuang327 discloses “wherein the circular shift is performed to the code
`
`sequence having the second length such that either a rear portion of the code se-
`
`quence having the second length moves to a start of the code sequence having
`
`the second length, or a front portion of the code sequence having the second

`length moves to an end of the code sequence having the second length,” as re-
`
`cited in claim 1. For example, Zhuang327 discloses the circular shift is performed
`
`to the time-domain access signal 130 having the second length NFFT/IFFT: “for each
`
`ranging code, Nsh cyclic time shifts 603 of the time-domain ranging signal (phase
`
`rotation in frequency domain) can be used to further increase the number of rang-
`
`ing opportunities. Ex. 1007, 6:30-45. See Wells Declaration, ¶¶ 127-128.
`
` More specifically, FIG. 6 (reproduced and annotated below) of Zhuang327
`
`shows three examples of cyclically-shifted access signals 140a, 140b, and 140c of
`
`the original time-domain access signal 130. To be sure, Zhuang327 discloses that a
`
`cyclic prefix (CP) can be added to the access signal 130 or to cyclically-shifted ac-
`
`cess signals 140a, 140b, and 140c to form access waveforms. Ex. 1007, 5:29-36.
`
`The resulting ranging/access waveforms are denoted as 150, 150a, 150b, and 150c
`
`in FIG. 6: the access waveform 150 results from adding CP1 from the original,
`
`non-circularly-shifted access signal 130; and the access waveforms 150a, 150b,
`
`and 150c result from adding CP2, CP3 and CP4 to the circularly-shifted access sig-
`
`nals 140a, 140b, and 140c, respectively.8
`
`
`8 Notably, the CP1, CP2, CP3 and CP4 shown in FIG. 6 are cyclic prefixes applied
`
`to time-domain circularly-shifted access signals 140 to form access waveforms

`Excerpt of FIG. 6 of Zhuang327 - with annotations by Petitioner
`
`The three circularly-shifted access signals 140a, 140b, and 140c result from
`
`circularly shifting a rear portion (CP1) of the original access signal 130 “in time
`
`domain by some multiples of L.” Ex. 1007, 6:30-45. The embodiment referred to
`
`as “3rd shift” shows that the circular shift is performed to the code sequence having
`
`
`150, and are distinguished from the cyclic postfixes used to cyclically extend GCL
`
`sequences 110 to form access/ranging sequences 120. See Petitioner-FIG. 2.

`the second length (i.e., non-circularly-shifted access signal 130, the “original (or
`
`0th shift) sequence,” Ex. 1007, 6:38) such that the rear portion of the code sequence
`
`having the second length (i.e., CP1 of the original access signal 130) moves to a
`
`start of the code sequence having the second length (i.e., a start of the original ac-
`
`cess signal 130). “Lastly, a CP [i.e., CP4] is added to form the final ranging wave-
`
`form [150c].” Ex. 1007, 5:33-34. See Wells Declaration, ¶¶ 129-133.
`
` Zhuang327 anticipates claim 2
`
`
`
`Zhuang327 discloses “the part of the code sequence having the first length
`
`comprises at least a cyclic prefix or a cyclic postfix,” as recited in claim 2. Based
`
`on antecedent, “the part of the code sequence having the first length” refers to “a
`
`part of the code sequence having the first length, having a length corresponding to
`
`a difference between the first length and the second length” as recited in claim 1.
`
`In other words, “the part of the code sequence having the first length” is the pad-
`
`ding portion added to the sequence. See Wells Declaration, ¶ 134. Zhuang327 dis-
`
`closes such a padding portion comprises at least a cyclic postfix as Zhuang327
`
`makes clear that “(K-NG) terms from the beginning of each GCL sequence” (de-
`
`noted as 130 in Petitioner-FIG. 1) is appended to the end of the sequence of length
`
`NG as a cyclic postfix. Ex. 1007, 5:66-16:2. See Wells Declaration, ¶ 135.
