`
`approaches, you know, that we discussed,
`
`Li takes advantage of OFDMA's ability to
`
`allocate different subchannels to multiple
`
`users. And in this case Li's teaching is
`
`to apply different OFDM symbol durations
`
`to different subscribers to -- to
`
`ameliorate the -- the problem --
`
`BY MR. SCHMIDT:
`
`Q.
`
`A.
`
`And then -- go ahead.
`
`-- so I was going to say that, you
`
`know, the specific example is -- there's a
`
`figure copied from Li and quoted, and so I'll
`
`just complete by reading Paragraph 99 and 100.
`
`[as read] ***Specifically, Li teaches that the
`
`system could transmit to the fast subscriber two
`
`OFDMA symbols in two slots with symbol
`
`duration -- half the symbol duration, two sub C
`
`each, so Li discloses a system high mobility
`
`users with a shorter symbol period than -- than,
`
`you know, the -- the baseline system.
`
`Q.
`
`Would a shorter symbol period also
`
`imply that you will get more pilot signal
`
`symbols per unit of time?
`
`MR. DETRIXHE: Same objection.

`
`Form.
`
`THE WITNESS: So depending on how
`
`you -- there's a nuance how you framed
`
`that question, yes, because if we mean by
`
`density, you know, the number of pilot
`
`symbols we are unit time -- so let's say
`
`I have two designs in which I have a
`
`symbol duration T and then I have a
`
`symbol duration T by two, if I keep the
`
`same number of pilots in the T symbol
`
`duration compared to the T by 2 I would
`
`get more pilots per unit time but per
`
`symbol duration the number of pilots are
`
`the same, so.
`
`BY MR. SCHMIDT:
`
`Q.
`
`A POSITA would have understood that
`
`at the time of Li?
`
`A.
`
`The POSITA would have understood
`
`that, yes.
`
`Q.
`
`Okay. So do you have the
`
`Li reference in front of you?
`
`A.
`
`Q.
`
`Let me see.
`
`Li is patent application ending in
`
`387. Exhibit 1016.
