3.1 Terms

For the purposes of the present document, the terms given in 3GPP 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 3GPP TR 21.905 [1].

Antenna connector: connector at the conducted interface of the repeater type 1-C

Fractional bandwidth: fractional bandwidth FBW is defined as

gap between passbands: frequency gap between two consecutive passbands that belong to the same operating band, where the RF requirements in the gap are based on co-existence for un-coordinated operation

Inter-passband gap: The frequency gap between two supported consecutive passbands that belong to different operating bands.

Maximum passband output power: mean power level measured per passband at the antenna connector, during the transmitter ON state in a specified reference condition

Maximum passband TRP output power: mean power level measured per passband during the transmitter ON state in a specified reference condition and corresponding to the declared rated passband TRP output power (P_rated,p,,TRP)Measurement bandwidth: RF bandwidth in which an emission level is specified

multi-band connector: Antenna Connector for a Multi-band repeater.

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

Non-contiguous spectrum: spectrum consisting of two or more passbands separated by inter-passband gap(s).

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

Repeater type 1-C:Repeater operating at FR1 with a requirement set consisting only of conducted requirements defined at individual antenna connectors.

Requirement set: one of the NR requirements set as defined for NR repeater

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.

Sub-band: A sub-band of an operating band contains a part of the uplink and downlink frequency range of the operating band.

sub-block: one contiguous allocated block of spectrum for transmission and reception by the repeater.

Superseding-band: A superseding-band of an operating band includes the whole of the uplink and downlink frequency range of the operating band.

Transmitter OFF state: Time period during which the repeater downlink or uplink is not allowed to transmit in the corresponding direction.
