IEEE 1609.4-2006 pdf free.IEEE Trial-Use Standard for Wireless Access in Vehicular Environments (WAVE)- Multi-channel Operation.
IEEE 1609.4 describes multi-channel wireless radio operations. WAVE mode, medium access control (MAC) and physical layers (PFIYs). including the operation of control channel (CCH) and service channel (SCI-l) interval timers, parameters for priority access, channel switching and routing, management services, and primitives designed for multi-channel operations.
1.2 Purpose
To enable effective mechanisms that control the operation of upper layer across multiple channels, without requiring knowledge of PHY parameters. and describe the multi-channel1 operaion channel routing and switching for different scenarios,

3.1 Definitions
For the purpose of this document, the following terms and definitions apply. The glossary in Annex E or The A,ahoriiaiiie Dictionary of IEEE Standards Ternas [B ij should be referenced for terms not defined in this clause.
3.1.1 communications zone: The space within which one device can communicate with another device. As these devices may have differing effective ranges of operation, the communication zone will be limited to the smallest operating range for the devices involved.
3.1.2 control channel (CCH): A radio channel used for exchange of management frames and WAVE short messages (WSMs).
3.1.3 EtherType: The Ethernet type field defined in RFC l042, used to identify the higher layer protocol above logical link control (LLC).
3.1.4 onhoard unit (OBU): A WAVE device that can operate when in motion and supports the information
exchange with roadside units (RSUs) or other OHUs.
3.1.5 provider: Initiator of a WAVE basic service set (WBSS). or sender of WSMs.
3.1.6 roadside unit (RSU): A WAVE device that operates only when stationary and supports information exchange with OBUs.9
3.1.7 secured WSA: The WAVE service advertisement (WSA) signed by the security services specified in IEEE Std 1609.2 and IEEE P 1609.3.
3.1.8 service channel (SCH): Secondary channels used for application specific information exchanges.
3.1.9 transmitter profile: A data object containing communication parameters to be used by the transmitter, including SCH number, power level, data rate and the adaptable status of power level, and data rate for Internet Protocol (IP)-hased applications.
3.1.10 user: A device that acts on the received WAVE announcement action frames.
3.1.11 WAVE basic service set (WBSS): A set of two or more WAVE devices participating in communications among each other on an SC!!. A WBSS is initiated by a WAVE device using a WAVE announcement action frame on the CCFI.
3.1.12 WAVE device: A device that contains an implementation of the WAVE protocol standards, including IEEE Std 1609.2, IEEE P1609.3, IEEE Sid 1609.4, and IEEE P802.1 Ip.
3.1.13 WAVE management entity (ME): The set of management functions required to provide WAVE networking services. It is specified in IEEE P 1609.3.IEEE 1609.4 pdf free download.
