Change Request on 802.16m SDD, IEEE 802.16m-08/003r9
Abstract:
The contribution proposes text changes to the section 15.2-Types of Base stations of the 802.16m SDD, IEEE 802.16m-08/003r9a.
Purpose:
To be discussed and adopted into the 802.16m SDD by TGm.

Introduction
• Types of Femtocell BS in SDD
– CSG-Closed
– CSG-Open
– OSG (Open Subscriber Group)
• These names are not easy to understand and may lead to
confusion.
– The terms CSG-Open and CSG-Closed are not
intuitively clear related to the CSG itself
2
Proposed
• We suggest categorizing the Femtocell BS into three
kinds of types
– Closed Subscriber Group (CSG)
– Semi-Closed Subscriber Group (SCSG)
– Open Subscriber Group (OSG)
• Definition and explanations of the SCSG
– CSG is a subset of SCSG (shown as below)
– SCSG shall support MSs with either members or non-members
– SCSG shall support seamless roaming function among different
SCSGs if these SCSGs belong to different operators

Proposed Text For SDD
15.2 Support for Femtocell
• CSG-Closed Femtocell BS: A CSG-Closed Femtocell BS is
accessible only to the MSs, which are in its CSG, except for
emergency services. MSs which are not the members of the CSG,
should not try to access CSG-Closed Femtocell BSs.
• Semi-CSG (SCSG) CSG-Open Femtocell BS: A SCSG CSG-Open
Femtocell BS is primarily accessible to the MS’s that belong to its
SCSG, while other MS’s, outside SCSG CSG, may also access such
Femtocell BS, will be served at lower priority. SCSG CSG-Open
Femtocell BS will provide service to such MSs’ as long as the QoS of
MSs in its CSG is not compromised. for seamless connection service,
SCSG shall support roaming function among different SCSGs if these
SCSGs belong to different operators.
• OSG (Open Subscriber Group) Femtocell BS: An OSG Femtocell BS
is accessible to any MSs.
