3.1 Definitions
For the purposes of the present document, the terms and definitions given in TR 21.905 [1] and the following apply. A term defined in the present document takes precedence over the definition of the same term, if any, in TR 21.905 [1].
ancillary equipment: electrical or electronic equipment, that is intended to be used with a receiver or transmitter
NOTE: It is considered as an ancillary equipment if:
the equipment is intended for use with a receiver or transmitter to provide additional operational and/or control features to the radio equipment, (e.g. to extend control to another position or location); and
the equipment cannot be used on a stand alone basis to provide user functions independently of a receiver or transmitter; and
the receiver or transmitter, to which it is connected, is capable of providing some intended operation such as transmitting and/or receiving without the ancillary equipment (i.e. it is not a sub-unit of the main equipment essential to the main equipment basic functions).
antenna port: for EMC purposes, port for connection of an antenna used for intentional transmission and/or reception of radiated RF energy, equivalent to an RF antenna connector.
channel bandwidth: the RF bandwidth supporting a single NR RF carrier with the transmission bandwidth configured in the uplink or downlink of a cell. The channel bandwidth is measured in MHz and is used as a reference for transmitter and receiver RF requirements.
continuous phenomena: electromagnetic disturbance, the effects of which on a particular device or equipment cannot be resolved into a succession of distinct effects (IEC 60050-161 [20]).
exclusion band: frequency range(s) not subject to test or assessment.
multi-band repeater: Repeater Type 1-C whose antenna connector is associated with a transmitter and/or receiver that is characterized by the ability to process two or more passband(s) in common active RF components simultaneously, where at least one passband is configured at a different operating band than the other passband(s) and where this different operating band is not a sub-band or superseding-band of another supported operating band
operating band: frequency range in which NR operates (paired or unpaired), that is defined with a specific set of technical requirements.
passband edge: Frequency at the edge of the passband
port: A particular interface, of the specified equipment (apparatus), with the electromagnetic environment. For example, any connection point on an equipment intended for connection of cables to or from that equipment is considered as a port (see Figure 3.1-1).
Figure 3.1-1: Examples of ports
repeater type 1-C: Repeater operating at FR1 with a requirement set consisting only of conducted requirements defined at individual antenna connectors.
repeater type 2-O: Repeater operating at FR2 with a requirement set consisting only of OTA requirements defined at the RIB
radiated interface boundary: operating band specific radiated requirements reference where the radiated requirements apply
signal/control port: port intended for the interconnection of components of an EUT, or between an EUT and associated equipment and used in accordance with relevant functional specifications (for example for the maximum length of cable connected to it).
single-band connector: Repeater type 1-C antenna connector supporting operation either in a single operating band only, or in multiple operating bands but does not meet the conditions for a multi-band connector
spatial exclusion zone: range of angles where no tests of radiated immunity are made for repeater type 2-O (i.e. half sphere around the EUT’s radiating direction).
telecommunication port: ports which are intended to be connected to telecommunication networks (e.g. public switched telecommunication networks, integrated services digital networks), local area networks (e.g. Ethernet, Token Ring) and similar networks.
NOTE: Telecommunication port is called "wired network port" in CISPR 32 [5] and ETSI EN 301 489-1 [21].
transient phenomena: pertaining to or designating a phenomena or a quantity which varies between two consecutive steady states during a time interval short compared with the time-scale of interest (IEC 60050-161 [20]).
