The scope of this standard is the specification of medium access control (MAC) sublayer functions and services that support multi-channel wireless connectivity between IEEE 802.11 Wireless Access in Vehicular Environments (WAVE) devices. Purpose To enable effective mechanisms that control the operation of upper layer data transfers across multiple channels@ without requiring knowledge of physical layer (PHY) parameters@ and describe the multi-channel operation channel routing and switching for different scenarios.
