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.
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.
Aggregated Channel Bandwidth:
The RF bandwidth in which a UE is configured to transmit and receive multiple contiguously aggregated carriers.
UL/DL common spectrum in which the UE supports the configuration of uplink or downlink CCs.
the ability of the UE to select a suitable beam for UL transmission based on DL measurements with or without relying on UL beam sweeping.
Aggregation of two or more component carriers in order to support wider transmission bandwidths.
Carrier aggregation band:
A set of one or more operating bands across which multiple carriers are aggregated with a specific set of technical requirements.
Carrier aggregation bandwidth class:
A class defined by the aggregated transmission bandwidth configuration and maximum number of component carriers supported by a UE.
Carrier aggregation configuration:
A combination of CA operating band(s) and CA bandwidth class(es) supported by a UE.
Cumulative aggregated channel bandwidth:
The cumulative aggregated channel bandwidth is defined as the frequency band from the lowest edge of the lowest CC to the upper edge of the highest CC of all UL and DL configured CCs inside the bidirectional spectrum of the UE.
EIRP(Link=Link angle, Meas=Link angle):
measurement of the UE such that the link angle is aligned with the measurement angle. EIRP (indicator to be measured) can be replaced by EIS, Frequency, EVM, carrier Leakage, In-band eission and OBW.
measurement of the EIRP of the UE such that the measurement angle is aligned with the beam peak direction within an acceptable measurement error uncertainty. EIRP (indicator to be measured) can be replaced by Frequency, EVM, carrier Leakage, In-band emission and OBW
measurement of the EIRP spherical coverage of the UE such that the EIRP link and measurement angles are aligned with the directions along the spherical coverage grid within an acceptable measurement error uncertainty. Alternatively, the spherical coverage grid can be replaced by the beam peak search grid as the results from the beam peak search can be re-used for spherical coverage.
EIS (effective isotropic sensitivity):
sensitivity for an isotropic directivity device equivalent to the sensitivity of the discussed device exposed to an incoming wave from a defined AoA
measurement of the EIS of the UE such that the measurement angle is aligned with the RX beam peak direction within an acceptable measurement error uncertainty.
Group of carrier aggregation bandwidth classes for which it is mandatory for a UE to be able to fallback to lower order CA bandwidth class configuration. It is not mandatory for a UE to be able to fallback to lower order CA bandwidth class configuration that belong to a different fallback group
IBM (Independent Beam Management):
A UE that supports inter-band CA with IBM selects its DL and UL beam(s) for all CCs in each configured band based on DL reference signals measurements made in that band.
Inter-band carrier aggregation:
Carrier aggregation of component carriers in different operating bands.
Intra-band contiguous carrier aggregation:
Contiguous carriers aggregated in the same operating band.
Intra-band non-contiguous carrier aggregation:
Non-contiguous carriers aggregated in the same operating band.
a DL-signal AoA from the view point of the UE, as described in Annex J. If the beam lock function is used to lock the UE beam(s), the link angle can become any arbitrary AoA once the beam lock has been activated.
the angle of measurement of the desired metric from the view point of the UE, as described in Annex J
radiated interface boundary:
operating band specific radiated requirements reference point where the radiated requirements apply
radiated requirements reference point:
for the RF measurement setup, the radiated requirements reference point is located at the centre of the quiet zone. From the UE perspective the reference point is the input of the UE antenna array
RX beam peak direction:
direction where the maximum total component of RSRP and thus best total component of EIS is found
This is one contiguous allocated block of spectrum for transmission and reception by the same UE. There may be multiple instances of sub-blocks within an RF bandwidth.
TX beam peak direction:
direction where the maximum total component of EIRP is found
TRP(Link=TX beam peak direction, Meas=TRP grid):
measurement of the TRP of the UE such that the measurement angles are aligned with the directions of the TRP grid points within an acceptable measurement uncertainty while the link angle is aligned with the TX beam peak direction
UE transmission bandwidth configuration:
Set of resource blocks located within the UE channel bandwidth which may be used for transmitting or receiving by the UE.
Rounding upwards; ceil(x) is the smallest integer such that ceil(x) ≥ x
The measured total EIRP based on the beam the UE chooses autonomously (corresponding beam) to transmit in the direction of the incoming DL signal, which is based on beam correspondence without relying on UL beam sweeping
The measured total EIRP based on the beam yielding highest EIRP in a given direction, which is based on beam correspondence with relying on UL beam sweeping
