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.
eRedCap UE:
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.
RedCap UE:
Switching SCell (sSCell):
The SCell configured with cross-carrier scheduling to PCell/PSCell.
For the purposes of the present document, the following symbols apply:
MaxDLDataRate:
Maximum DL data rate
MaxDLDataRate_MN:
Maximum DL data rate in the MN
MaxDLDataRate_SN:
Maximum DL data rate in the SN
MaxULDataRate:
Maximum UL data rate
MaxSLtxDataRate:
Maximum SL data rate in transmission
MaxSLrxDataRate:
Maximum SL data rate in reception
For the purposes of the present document, the abbreviations given in
