General discovery comment resolution overview Authors: Date: 2010-03-02 Kazuyuki Sakoda, Sony Corporation
Abstract • Summary of the suggested resolution text (11-10/236r0) • Clean up the clause 11C.1 Mesh discovery. • Amend the definition of BSS. • Clarify what is Mesh Profile. • Use START primitive to become a member of a mesh BSS. • Use “become a member of a mesh BSS” consistently, instead of “join a mesh BSS”. • Add the missing MIB variables. • Add the missing PICS table entries.

Clean up the clause 11C.1 Mesh discovery • Clause 11C.1 has been modified significantly • Original 11C.1 does not provide appropriate procedures for discovery. • The new subclause structure is as follows: • 11C.1 Mesh discovery • 11C.1.1 General • 11C.1.2 Mesh identifier • 11C.1.3 Mesh profile • 11C.1.4 Supplemental information for mesh discovery • 11C.1.5 Scanning mesh BSS • 11C.1.6 Determination of the candidate peer mesh STA • 11C.1.7 Establishing or becoming a member of a mesh BSS Kazuyuki Sakoda, Sony Corporation
Definition of BSS and mesh profile • Amend the definition of BSS as follows: • 3.25 basic service set (BSS): A set of stations (STAs) that have successfully synchronized using the JOIN service primitives and one STA that has used the START primitive. Alternatively, a set of STAs that have used the START primitive specifying the same mesh profile as neighbor STA or a STA that has used the START primitive without having a neighbor STA that specifies the same mesh profile.Membership in a BSS does not imply that wireless communication with all other members of the BSS is possible. • Add the definition of mesh profile as follows: • 3.s13 mesh profile: A set of parameters that identifies the attribute of the mesh BSS and are commonly used in a single mesh BSS. The mesh profile consists of mesh ID, active path selection protocol, actie path selection metric, congestion control mode, synchronization protocol, and authentication protocol. • Explicitly position “mesh profile” as the MBSS attribute identifiers.

Use START primitive • Traditionally, STA uses START primitive to start (establish) a new BSS, and use JOIN primitive to join the existing BSS. • START primitive kicks beaconing. • JOIN primitive kicks sync assuming a single TSF value is shared in a BSS. This is not applicable for mesh STAs. • Mesh STAs use START primitive regardless of the establishment or becoming a member of a BSS. • Aligned with 11-10/135r1 (START primitive proposal) • Use START to establish a mesh BSS (the same procedure as legacy BSS) • Use START to become a member of a mesh BSS (start beaconing) • Use “become a member of a mesh BSS” consistently, instead of “join a mesh BSS”, as join implies starting synchronization.

MIB and PICS updates • Many MIB variables are missing to control the discovery related parameters. • dot11MeshNumberOfPeerings • dot11MeshAcceptingAdditionalPeerings • dot11MeshConnectedToPortal • dot11MeshActiveAuthenticationProtocol • dot11MeshActivePathSelectionMetric • dot11MeshActiveCongestionControlMode • dot11MeshActiveSynchronizationProtocol • Further, specify how these MIB variables to be used. • Add the missing PICS table entries regarding: • Discovery related information • Mesh peering management Kazuyuki Sakoda, Sony Corporation
Summary • All G-discovery category comments are examined and resolution text is available to close most of the comments • 11-10/236 provides the resolution text • 11-10/237 provides the resolution notes to each comments • The remaining comment (CID2389) requires discussion with security experts Kazuyuki Sakoda, Sony Corporation
