Re: [STDS-802-16] destination address

Hi Jose,
 
Thanks for your reply.I agree CID's are used for forwarding packets,but in MAC header we have only one CID field,is that CID indicates source CID or destination CID.
 
we have two cases in it
 
a.In a point to multipoint system if the CID in MAC header indicates destination then how come the SS's come to know other SS's CID  and how come the BS come to know the source CID sending that packet.
 
b.If the CID indicates source CID then how come the BS will forward the packet to the destination SS.
 
Please help me in sorting out this issue

In 802.16 the MAC addresses are not the basis for forwarding packets. Instead CIDs are used. These can be unicast, multicast or broadcast.
 
thanks & best regards,

Hi all,
 
In 802.16 point to multipoint, if a subscriber station(SS1) needs to send a packet to another subscriber station(SS2) then,how does a SS1 comes to know the destination address(b'coz in 802.11 MAC header we have source MAC address & destination MAC address fields.)
 
Thanks in advance
