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].
Carrier: The modulated waveform conveying the LCR TDD physical channels
Channel bandwidth: The RF bandwidth supporting a single LCR TDD 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.
Channel edge: The lowest and highest frequency of the LCR TDD carrier, separated by the channel bandwidth.
Donor coupling loss: is the coupling loss between the repeater and the donor base station.
Downlink: Signal path where base station transmits and mobile receives.
Maximum output power, Pmax: This is the mean power level per carrier measured at the antenna connector of the Repeater in specified reference condition.
Output power, Pout: This is the mean power of one carrier at maximum repeater gain delivered to a load with resistance equal to the nominal load impedance of the transmitter.
Pass band: The repeater can have one or several pass bands. The pass band is the frequency range that the repeater operates in with operational configuration. This frequency range can correspond to one or several consecutive nominal channels. If they are not consecutive each subset of channels shall be considered as an individual pass band.
Rated output power: Rated output power of the repeater is the mean power level per carrier that the manufacturer has declared to be available at the antenna connector.
Repeater: A device that receives, amplifies and transmits the radiated or conducted RF carrier both in the down-link direction (from the base station to the mobile area) and in the up-link direction (from the mobile to the base station)
Transmission bandwidth: Bandwidth of an instantaneous transmission from a UE or BS, measured in Resource Block units.
Transmission bandwidth configuration: The highest transmission bandwidth allowed for uplink or downlink in a given channel bandwidth, measured in Resource Block units.
Uplink: Signal path where mobile transmits and base station receives.
