3 Definitions, symbols and abbreviations
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.

3GPP TS 25.116 version 15.0.0 Release 15 7 ETSI TS 125 116 V15.0.0 (2018-07)
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.

4.1 Relationship between Minimum Requirements and Test
Requirements
The Minimum Requirements given in this specification make no allowance for measurement uncertainty. The test
specification TS 25.153 section 4 defines Test Tolerances. These Test Tolerances are individually calculated for each
test. The Test Tolerances are used to relax the Minimum Requirements in this specification to create Test Requirements.
The measurement results returned by the Test System are compared - without any modification - against the Test
Requirements as defined by the shared risk principle.
The Shared Risk principle is defined in ITU-R M.1545 [3].

5 Frequency bands and channel arrangement
5.1 General
The information presented in this section is based on the chip rates of 1.28 Mcps TDD.
NOTE: Other chip rates may be considered in future releases.
5.2 Frequency bands
UTRA/TDD is designed to operate in the following bands;
a) 1900 - 1920 MHz: Uplink and downlink transmission
2010 - 2025 MHz Uplink and downlink transmission
b) 1850 - 1910 MHz Uplink and downlink transmission
1930 - 1990 MHz Uplink and downlink transmission
c) 1910 - 1930 MHz Uplink and downlink transmission
d) 2570 - 2620 MHz Uplink and downlink transmission
e) 2300 - 2400 MHz Uplink and downlink transmission
f) 1880 - 1920 MHz: Uplink and downlink transmission
Note: Deployment in existing and other frequency bands is not precluded.
The co-existence of TDD and FDD in the same bands is still under study in WG4.
5.3 TX-RX frequency separation
No TX-RX frequency separation is required as Time Division Duplex (TDD) is employed. Each subframe consists of 7
main timeslots where all main timeslots (at least the first one) before the single switching point are allocated DL and all
main timeslots (at least the last one) after the single switching point are allocated UL.
