3 Definition of terms, symbols and abbreviations
3.1 Terms

For the purposes of the present document, the terms given in Directive 2014/53/EU [i.3] and the following apply:

adjacent channel: channel at a distance of 5 MHz relative to the centre frequency, i.e. in the channel at the next upper

or lower centre frequency
bit: acronym for "binary digit" which can have one out of two possible values
EXAMPLE: 0/1, or +1/-1, or low/high.

bit rate: number of bits occurring per unit time, usually expressed in bits per second

boresight: direction of maximum radiation of a directional antenna
carrier frequency: frequency f to which the RSU transmitter is tuned

carrier signal or carrier: harmonic signal whose nominal single frequency f is capable of being modulated by a

second, symbol-carrying signal

channel: continuous part of the radio-frequency spectrum to be used for a specified emission or transmission

NOTE: A radio-frequency channel may be defined by two specified limits, or by its centre frequency and its

bandwidth, or any equivalent indication. It is often designated by a sequential number. A radio-frequency

channel may be time-shared in order to allow radio communication in both directions by simplex

operation. The term "channel" is sometimes used to denote two associated radio-frequency channels, each

of which is used for one of two directions of transmission, i.e. in fact a telecommunication circuit.

co-channel: transmission using the same uplink or downlink channel in a frequency band of 5 MHz width

For the purposes of the present document, the terms given in Directive 2014/53/EU [i.3] and the following apply:

adjacent channel: channel at a distance of 5 MHz relative to the centre frequency, i.e. in the channel at the next upper

or lower centre frequency
bit: acronym for "binary digit" which can have one out of two possible values
EXAMPLE: 0/1, or +1/-1, or low/high.

bit rate: number of bits occurring per unit time, usually expressed in bits per second

boresight: direction of maximum radiation of a directional antenna
carrier frequency: frequency f to which the RSU transmitter is tuned

carrier signal or carrier: harmonic signal whose nominal single frequency f is capable of being modulated by a

second, symbol-carrying signal

channel: continuous part of the radio-frequency spectrum to be used for a specified emission or transmission

NOTE: A radio-frequency channel may be defined by two specified limits, or by its centre frequency and its

bandwidth, or any equivalent indication. It is often designated by a sequential number. A radio-frequency

channel may be time-shared in order to allow radio communication in both directions by simplex

operation. The term "channel" is sometimes used to denote two associated radio-frequency channels, each

of which is used for one of two directions of transmission, i.e. in fact a t
