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].
eRedCap UE: a UE with enhanced reduced capabilities as specified in clause 4.2.22.1.
Fallback band combination: A Uu band combination that would result from another Uu band combination (parent
band combination) by releasing at least one SCell or uplink configuration of SCell, or SCG, or SUL. A PC5 band
combination that would result from another PC5 band combination (parent band combination) by releasing at least one
sidelink carrier. An intra-band non-contiguous band combination is not considered to be a fallback band combination of
an intra-band contiguous band combination. A fallback band combination supports the same channel bandwidth(s) for
each carrier as its parent band combination(s).
Fallback per band feature set: A feature set per band that has same or lower capabilities than the reported capabilities
from the reported feature set per band for a given band.
Fallback per CC feature set: A feature set per CC that has same or lower capabilities than the capabilities of UE (e.g.
supported MIMO layers, BW, modulation order) while keeping the numerology the same from the reported feature set
per CC for a given carrier per band. The supportedMinBandwidthDL/supportedMinBandwidthUL defines the lower
bound of the bandwidth supported by the UE.

3GPP TS 38.306 version 19.2.0 Release 19 9 ETSI TS 138 306 V19.2.0 (2026-04)
RedCap UE: The UE with reduced capabilities as specified in clause 4.2.21.1.
SON report(s): A SON report corresponds to one report from UE such as Random Access report, Radio Link Failure
report, Connection Establishment Failure report, Mobility History Information report, Successful Handover report, and
Successful PSCell change report.
Switching SCell (sSCell): The SCell configured with cross-carrier scheduling to PCell/PSCell.

4.1 Supported max data rate
4.1.1 General
The DL, UL and SL max data rate supported by the UE is calculated by band or band combinations supported by the
UE. A UE supporting NR (NR SA, MR-DC) shall support the calculated DL and UL max data rate defined in 4.1.2. A
UE supporting NR sidelink communication shall support the calculated SL max data rate defined in 4.1.5.
4.1.2 Supported max data rate for DL/UL
For NR, the approximate data rate for a given number of aggregated carriers in a band or band combination is computed
as follows.

( j)
OH is the overhead and takes the following values

0.18, for frequency range FR2 for DL
0.08, for frequency range FR1 for UL
0.10, for frequency range FR2 for UL
NOTE 1: Only one of the UL or SUL carriers (the one with the higher data rate) is counted for a cell operating
SUL.
NOTE 2: For UL Tx switching between carriers, only the supported MIMO layer combination across carriers that
results in the highest combined data rate is counted for the carriers in the supported maximum UL data
rate.
The approximate maximum data rate can be computed as the maximum of the approximate data rates computed using

For EUTRA in case of MR-DC, the approximate data rate for a given number of aggregated carriers in a band or band

wherein
J is the number of aggregated EUTRA component carriers in MR-DC band combination
��� is the total maximum number of DL-SCH transport block bits received or the total maximum number of
�
UL-SCH transport block bits transmitted, within a 1ms TTI for j-th CC, as derived from TS 36.213 [19] based on
the UE supported maximum MIMO layers for the j-th CC, and based on the maximum modulation order for the
j-th CC and number of PRBs based on the bandwidth of the j-th CC according to indicated UE capabilities.
The approximate maximum data rate can be computed as the maximum of the approximate data rates computed using
the above formula for each of the supported band or band combinations.
For MR-DC, the approximate maximum data rate is computed as the sum of the approximate maximum data rates from
NR and EUTRA.

4.1.4 Total layer 2 buffer size for DL/UL
The total layer 2 buffer size is defined as the sum of the number of bytes that the UE is capable of storing in the RLC
transmission windows and RLC reception and reassembly windows and also in PDCP reordering windows for all radio
bearers.
The required total layer 2 buffer size in MR-DC is the maximum value of the calculated values based on the following
equations:
- MaxULDataRate_MN * RLCRTT_MN + MaxULDataRate_SN * RLCRTT_SN + MaxDLDataRate_SN *
RLCRTT_SN + MaxDLDataRate_MN * (RLCRTT_SN + X2/Xn delay + Queuing in SN)
- MaxULDataRate_MN * RLCRTT_MN + MaxULDataRate_SN * RLCRTT_SN + MaxDLDataRate_MN *
RLCRTT_MN + MaxDLDataRate_SN * (RLCRTT_MN + X2/Xn delay + Queuing in MN)
Otherwise it is calculated by MaxDLDataRate * RLC RTT + MaxULDataRate * RLC RTT.
NOTE: Additional L2 buffer required for preprocessing of data is not taken into account in above formula.
The required total layer 2 buffer size is determined as the maximum total layer 2 buffer size of all the calculated ones
for each band combination and the applicable Feature Set combination in the supported MR-DC or NR band
combinations. The RLC RTT for NR cell group corresponds to the smallest SCS numerology supported in the band
combination and the applicable Feature Set combination.
wherein
X2/Xn delay + Queuing in SN = 25ms if SCG is NR, and 55ms if SCG is EUTRA
X2/Xn delay + Queuing in MN = 25ms if MCG is NR, and 55ms if MCG is EUTRA
RLC RTT for EUTRA cell group = 75ms
RLC RTT for NR cell group is defined in Table 4.1.4-1
