Results for area 8 Dedicated Short Range Communications
averaged number of erroneous bits relative to the total number of transmitted bits
number of seconds passed since 1st January 1970, 00:00 (UTC)
NOTE This format is also known as ”UNIX time”.
T-APDU that contains a complete PDU
fragment header followed by part or all of the encoding of a value of the ASN.1 type T-APDUs
function performed by the transfer kernel to map one ASDU on multiple LSDUs
NOTE1 In ISO/IEC 7498-1, fragmentation is called segmentation.
NOTE2 The inverse function is called defragmentation or, in ISO/IEC 7498-1, disassembling.
unambiguously distinguishes an attribute from all other attributes within the same element
unique address used for addressing the mobile equipment
procedure used to establish communication between an RSU and a newly arrived OBU
provides and distributes values for the communication parameters for controlling the DSRC Communication stack
maximum power (density) emitted by the RSU transmitter as function of the frequency
assembly of communication parameters of all protocol layers such that a consistent communication protocol is provided
mobile communication facility capable of receiving information from the fixed equipment on the downlink and, optionally, also capable of transmitting information to the fixed equipment on the uplink
NOTE The mobile equipment normally corresponds to the vehicle’s communication unit.
function within the Transfer Kernel allowing simultaneous support for more that one Application in a single OBU
period of time during which the physical medium is allocated either to the fixed equipment or to the mobile equipment
downlink parameters apply to transmission of data from RSU to OBU
parameters apply to transmission of data from OBU to RSU
queuing discipline (also referred to as strict or fixed priority queuing), where a number of queues are served in priority order; a lower priority queue is served if all higher priority queues are empty, each queue is served in First-Come-First-Serve order, each user goes head of the line of the users of lower priorities but behind all users of equal or higher priority
polarisation of the electrical field strength (horizontal, vertical, left or right hand circular)
unique set of parameter values controlling the behaviour of the DSRC
consistent and standardised set of cross layer parameters in a specific DSRC implementation identified by a unique number
number of bits per second, independent of the data coding
interface point between data link layer and application layer that has a unique Link Identifier and that allows layers to communicate
the lower and upper optical wavelength describe the optical bandwidth of an IR radiátor; both the lower and upper optical wavelength of an IR radiator are defined by the reduction of the peak intensity by 3dB, taking into account the effects of temperature and component deviations
refers to the use of a neighbouring DSRC channel by two or more emissions
function performed by the Transfer Kernel to map multiple Application Layer Protocol Data Units or Application Layer Protocol Data Layer Fragments into one Data Link Layer Service Data Unit
data structure broadcast from the RSU to the OBUs
communication from the OBU to the RSU
function performed by the Transfer Kernel to link the execution of service primitives together
an instantaneous activity occurring spontaneously
the procedure used to terminate communication between a RSU and an OBU
refers to the use of a neighbouring DSRC channel by two or more emissions
NOTE It is possible that a DSRC channel has either one or two adjacent channels.
