IEEE 802.16K-2007 pdf download IEEE Standard for Local and metropolitan area networks Media Access Control (MAC) Bridges Amendment 5: Bridging of IEEE 802.16
6. Support of the MAC Service
6.5 Support of the Internal Sublayer Service by specific MAC procedures
Insert the following as new Subclause 6.5.5, renumbering the existing Subclause 6.5.5 as 6.5.6.6.5.5 Support by IEEE Std 802.16 (WMAN)
The Wireless Metropolitan Area Network (WMAN) MAC access method is specified in IEEE Std 802.16.Clause 5 of that standard specifies the Service Specific Convergence Sublayers (CS) that implement the802.16 MAC service. Subclause 5.2.4 (802.3 Packet CS) describes the mode of the Packet CS that supportsthe Internal Sublayer Service.
Subclauses 5.1 (ATM CS), 5.2.5 (IEEE Std 802.10M2003 virtual local area network (VLAN) specific part)and 5.2.6 (Packet CS IP specific part) shall not support the Internal Sublayer Service.
Multiple encapsulation methods are provided in the MAC CS in Clause 5. However the bridging functiondepends on the correct modeling of the Ethernet transport by the Ethernet CS only, and is indifferent to anyadditionalencapsulation.
Clause 6 specifies the MAC Common Part Sublayer (MAC CPS) transmission and reception procedures andAnnex C describes the MAC CPS service definition.
IEEE Std 802.16 includes no explicit definition of the MAC service definition for the 802.3 Packet CS. The802.3 Packet CS MAC service is defined in IEEE Std 802.3 Clause 2.
The 802.16 MAC CPS presents a connection-oriented MAC service. The 802.3 packet CS utilizes thisservice to present the 802.3 service. A pair of communicating peer CS entities between an 802.16 BS and an802.16 SS create a point-to-point LAN as defined in 6.4.3.
Since the 802.3 specific part of the packet CS does not forward the frame check sequence parameter of theM UNITDATAindication.then
1) Any service flow using this MAC CS shall enable the 802.16 MAC CRC
2) PHS validation shall not be turned off for this service flow (since 802.16 MAC CRC cannot protect suppressed MAC header fields).
6.5.5.1 Support for Internal Sublayer Service under IEEE Std 802.16 and IEEE Std 802.3 Packet CS
The frame_type, destination_address, source_address, mac_service_data_unit and user_priority parameters of the M_UNITDATA primitive are encoded as described in 6.5.1.
The value of operPointToPointMAC (6.4.3) shall be TRUE.
The value of MAC_Enabled shall be determined by the procedure described in 6.5.1.
