¿µ¹®³»¿ë¿ä¾à The standard comprises MAC sublayer and PHY layer. MAC sublayer provides MAC
data service and MAC management service. PHY layer provides PHY data service
and PHY management service.
Convergence sublayer (CS) is responsible for translation of external network data
received via the CS service access point (CS_SAP) into MAC service data units
(SDU) received by the MAC sublayer through the MAC_SAP. CS is not specified in
the standard.
CS, MAC sublayer, and PHY layer are controlled by convergence sublayer
management entity (CLME), MAC sublayer management entity (MLME), and PHY
layer management entity (PLME) respectively. CLME, MLME, and PLME are part of
a device management entity. The white space database SAP (WS_DB_SAP)
provides the interface to a white space database. The device management entity
and the white space database SAP interface are not specified in the standard.
