IEEE 1609.4-2016 pdf free.IEEE Standard for Wireless Access in Vehicular Environments (WAVE)-Multi-Channel Operation.
For the purposes of this document, the following terms and definitions apply. The IEEE Standards Dictionuri Onhnt’ should be consulted for terms not defined in this clause.
channel coordination: The mechanisms specified in this standard that facilitate Wireless Access in Vehicular Environments (WAVE) operation of at least one physical layer (PHY) over multiple wireless channels, including synchronization.
common time reference: Coordinated Universal Time (UTC). modulo I second.
control channel (CCH): A radio channel on which the only data frames allowed by the WAVE standards are those carrying WAVE Short Messages. See aI.co: service channel.
guard iiiterial: A time interval at the start of each time slot, during which devices using alternating channel access do not transmit.
managed Wireless Access in Vehicular Ens’irnnments (WAVE) desice: A WAVE device that supports management through the usc of an IEEE 1609 standards-defined management information base.
multi-channel operation: The operation of a Wireless Access in Vehicular Environments (WAVE) device to utilize more than one wireless channel, possibly involving channel coordination.
OfflActlvatcd: lndicatc communication outside the context of a basic serv icc set us specified in iEEE Std X02.ll (by setting dotIiOL’BActivatedto TRUE) (ic.. used for WAVE operation).
pseudonymiti: A property wherein an entity’s permanent or long-lived identities, and its long-term patterns of behavior, cannot be deduced from its network traffic and are only observable by appropriately authorized parties.
sers’ice channel (5(H): Any channel that is not the control channel. See also: control channel.
slnglc-phslcal laser (PIfl) desict’: A Wireless Access in Vehicular Environments (WAVE) device not capable of simultaneous operation on multiple radio channels.
sssitching device: A WAVE device with at least one physical layer (PIIY) that is switching between channels, e.g. service channel (SUfl and control channel (CCH).
sync interval: A repeating time interval comprised of one time slot 0 interval followed by one time slot I interval. See also. time slot 0; time slot 1.IEEE 1609.4 pdf download.
