Re: [STDS-802-16] look for UIUC 2 and 3 significance

Ramzi,
 
I am afraid you are slightly mistaken in your interpretation.
 
REQ Region Focussed is used for the focussed contention bandwidth request method, where requests from up to 48 separate SS can be received by the BS in parallel, at the expense of increased latency, as the BS then needs to allocate unicast regions to each of the requesting SS in which the SS can place its bandwidth request.

Subject: [STDS-802-16] look for UIUC 2 and 3 significance

Hi all,
Could anyone explain to me the significance of UIUC 2 and 3 that correspond respectively to "REQ Region full" and "REQ Region focused" in the UL-MAP of the OFDM physical layer.
As far I have understood, these UIUC are used to indicate respectively Bandwidth request contention period (Multicast and broadcast polling) and Bandwidth request as a unicast poll .
Am I rigth ? or no?
Best regards,
Ramzi TKA
