RE: stds-802-16-tg1: Question: Data broadcast in 802.16 MAC

[Ken Stanwood <ken@ensemble.com>]

Vladimir,

The broadcast connection is not a data transport connection, and user data
should not be sent on it.  There is the problem of connection parameters,
which convergence sublayer to use, etc. that would make it problematic, and
point out that it would actually be a layering violation.

Instead, if you need broadcast data under the current spec, you should set
up a multicast transport connection and have all SS belong to that multicast
connection, making it effectively broadcast.

Alternatively, if this broadcast data connection would always be present in
certain types of systems, you could define in the spec a well-known
broadcast data transport connection with well known parameters and
convergence sublayer.  That would eliminate the need to join every SS to the
multicast connection.

Carl and All,

Can you please clarify the issue of data broadcast in 802.16 MAC.
[Obviously, there may be a need for broadcasting data to all SSs]

If it is allowed to send data traffic at broadcast CID, then there may be a
problem with recognition 
of Management messages sent at the same CID. Such a recognition is needed to
decide whether we need 
to pick up Management Message Type for further parsing

Thanks
