The following documents contain provisions which, through reference in this text, constitute provisions of the present document.
References are either specific (identified by date of publication, edition number, version number, etc.) or non-specific.
For a specific reference, subsequent revisions do not apply.
For a non-specific reference, the latest version applies. In the case of a reference to a 3GPP document (including a GSM document), a non-specific reference implicitly refers to the latest version of that document in the same Release as the present document.
ITU-R Recommendation M.1545: "Measurement uncertainty as it applies to test limits for the terrestrial component of International Mobile Telecommunications-2000".
For the purposes of the present document, the terms and definitions given in TR 21.905 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.
Access link:
Link for communication between Relay and UE.
Backhaul link:
Link for communication between Relay and BS.
Carrier:
The modulated waveform conveying the E-UTRA or UTRA physical channels
Channel bandwidth:
The RF bandwidth supporting a single E-UTRA 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 E-UTRA carrier, separated by the channel bandwidth.
In-band relay:
A Relay where the access link and backhaul link operates in the same operating band.
Measurement bandwidth:
The bandwidth in which an emission level is specified.
Occupied bandwidth:
The width of a frequency band such that, below the lower and above the upper frequency limits, the mean powers emitted are each equal to a specified percentage β/2 of the total mean power of a given emission.
RRC filtered mean power:
The mean power of a UTRA carrier as measured through a root raised cosine filter with roll-off factor α and a bandwidth equal to the chip rate of the radio access mode.
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.
For the purposes of the present document, the abbreviations given in TR 21.905 and the following apply. An abbreviation defined in the present document takes precedence over the definition of the same abbreviation, if any, in TR 21.905.
