Text Proposal for the 802.16n Amendment Working Document (AWD)
Note:
The text in BLACK color: the existing text in the 802.16n Amendment Draft Standard
The text in RED color: the removal of existing 802.16n Amendment Draft Standard Text
The text in BLUE color: the new text added to the 802.16n Amendment Draft Standard Text
[-----------------------------------------------Start of Text Proposal---------------------------------------------------]
Modify various sections of the AWD [1] as indicated:
3. Definitions
3.163 Degraded backhaul: An HR-BS backhaul is considered degraded if its performance is reduced below that
which is required to maintain connectivity for its served HR-MS.
17.2.1.2 Relay function for HR-MS
An HR-MS may operate as an HR-RS to provide connectivity for multiple out-of-coverage HR-MSs. During
basic capability negotiation within at network entry, an HR-MS that is capable of role change to HR-RS shall
report such capability to the super-ordinate HR-BS/HR-RS.
2
IEEE C802.16n-11/0145
While operating as HR-RS, the station may maintain certain HR-MS functionalities. A mode switch to HR-RS
shall be commanded by its superordinate HR-BS.
If the HR-MS is released from its role from the relay modeas a relay, HR-MS may perform handover to the any
infrastructure station.
17.2.1.3 Base station function for HR-MS
An HR-MS may operate as an HR-BS to provide connectivity for itself and other HR-MSs. During basic
capability negotiation within at network entry, an HR-MS that is capable of role change to HR-BS shall report
such capability to the super-ordinate HR-BS/HR-RS.
17.2.2 Direct communication between HR-MSs
17.2.2.1 General Description
In HR-MS direct communication, the two communicating HR-MSs are the source and the sink of data. The data
packets are passed from upper layers to MAC at the source HR-MS and back to upper layers at the sink HR-MS.
Data packets are exchanged between the two HR-MSs directly or by passing through another HR-MS.
HR-MS direct communication is applicable when 1) the two HR-MSs are in coverage of and are directly
associated to an HR infrastructure station; 2) one HR-MS is in coverage of and directly associated to an HR
infrastructure station, while the other HR-MS is out of coverage of any HR infrastructure stations; 3) the two
HR-MSs are out of coverage of any HR infrastructure stations.
Resource for HR-MS direct communication can be allocated by the HR infrastructure station for cases (1) and
(2).
For case-3, direct communications between HR-MSs shall satisfy: ies
17.2.2.2 Frame Structure and Resource Allocation
…
When an infrastructure node doesn’t exist, one of the HR-MS shall fulfill this coordinating role. It is understood
that the coordinating HR-MS needs to take on some of the functionality of a HR-BS and may also require new
functionality.
All resource scheduling shall be dynamically conveyed through MAP or DL control messages from serving HRBS/RS or a coordinating HR-MS. In the case of HR-MS Forwarding to Network, the scheduling messages shall
be forwarded by the forwarding HR-MS.

17.3.2.6 Talk-around Direct Communication mode
HR-MSs by themselves synchronize and perform contention-based transmission. The synchronization and the
contention-based transmission are performed among those HR-MSs on a dedicated resource unused by HR-BSs
if at least one of the HR-MSs are is under HR-BS coverage.
