[STDS-802-16] Fwd: Uplink preambles - interpretation of 802.16 clause 8.4
>Dr. Marks,
>We are currently developing an 802.16 testbench, which will generate (in
>Matlab code) uplink subframe data.
>I have a question on the interpretation of an apparent ambiguity in the
>802.16-2004 standard. Please could you forward this to the relevant
>members of the working group, or let me know what the procedure is for
>resolving such queries?

>WirelessMAN-OFDMA Uplink preambles
>==================================
>As far as I can tell, it is not normal for a preamble to be included in an
>uplink burst, e.g. see Figure 218. There is a full specification of the
>downlink preamble (clause 8.4.6.1.1), but no specification for an uplink
>preamble, other than the optional embedded AAS preambles (e.g. clause
>8.4.4.6.4).
>
>However, the fact that PHYMOD_UL_IE can be present in a UL-MAP (clause
>8.4.5.4.14, table 302) implies that UL preambles *are* possible.
>
>So my question is:
>(a) is the presence of clause 8.4.5.4.14 an error?
>(b) if not, where is the complete specification for the formation of UL
>preambles?
>
>Thank you in advance,
