Relay AHG Recommendations for Relay Support in Network
Architecture
16jm ad hoc group
Introduction
This contribution contains the recommendation of the relay AHG for relay-related updates to the network
architecture section of the SDD. The contents in this contribution were drawn from
(a) the contributions and comments submitted for sessions 52, 53, and 54 listed in the table below,
(b) the ad-hoc group recommendations and the TG decisions made during sessions 54 and 55.
Only the relay-related aspects of network architecture are considered in this contribution.

The 16jm AHG makes the following recommendation for the relay-related network architecture.
Proposed Text
[Modify the text on page 7, lines 17-18 in document 802.16m-08_003r3.pdf as follows]:
The Relay Stations (RSs) may be deployed to provide improved coverage and/or capacity (Figure 2.). When RSs
are present, communications between the BS and the MS can occur directly or via the relay stations.
[Delete Figure 2 on page 8 of 802.16m-08_003r3.pdf]
[Replace the current caption of Figure 3 on page 9 as follows:]
Figure 3: Relay protocol support Diagram showing the relay-related connections.
[Replace the current caption of Table 1 on page 10 as follows:]
Table 1: Relay protocol support Interconnections between the entities shown in Figure 1 and the protocol used.
[Update the text on page 8, lines 7-12 as follows:]
Figure 3 and Table 1 show the 16m relay related interfaces that are to be supported and those which are not
required to be supported in the 802.16 specification. Only the interfaces involving RSs (16m and legacy RS) are
shown.
The 16j BS, shown in Figure xxx is referred to as an MR-BS in the 16j draft amendment. Figure 3 and Table 1
also indicate the specific 802.16 protocol that is to be used for supporting the particular connection. In Figure 3,
it is assumed that the 16m MS supports 16m and 16e air interface per SRD requirements.
[Insert the following text after Table 1 on page 10]

IEEE C802.16m-08/876
Figure 3 and Table 1 capture the interfaces which may exist between the 16m and legacy stations. The figure
and table are not intended to specify any constraints on the usage of these interfaces. For example, the figure and
table do not provide rules for which interfaces a particular station can utilize at the same time, or how many
connections a station can have over each of the specified interfaces.
The usage of the interfaces described in Figure 3 and Table 1 is constrained as follows: A 16m MS may connect
to a 16m BS either directly or via one or more 16m RSs. The number of hops between the 16m BS and a 16m
MS can be two or greater than two. The topology between the 16m BS and the subordinate 16m RSs within a
16m BS cell shall be restricted to a tree topology. A 16e MS may connect to a 16m BS either directly or via one
or more 16m RSs. Furthermore a 16e MS may connect to a 16m BS via one or more 16j RSs. The topology
between the 16m BS and the subordinate 16j RSs within a 16m BS cell is specified in the IEEE 802.16j draft
amendment.

[Insert the following text immediately after Table 1]
Connection 10 indicates a connection between a 16m RS and another directly connected 16m RS. Such
connections exist in order to support topologies in which the number of hops between the 16m BS and an MS is
greater than two hops.
Connection 11 indicates a connection between a 16j RS and another directly connected 16j RS. Such
connections exist in order to support topologies in which the number of hops between the 16j MR-BS and an
MS is greater than two hops.
