Aggregated Channel Bandwidth:
The RF bandwidth in which a UE transmits and receives multiple contiguously aggregated carriers.
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.
The simultaneous transmission and reception of sidelink and Uu interfaces while operation is agnostic of the service used on each interface.
A set of two or more carriers configured in a spectrum block where there are no RF requirements based on co-existence for un-coordinated operation within the spectrum block.
Contiguous resource allocation:
A resource allocation of consecutive resource blocks within one carrier or across contiguously aggregated carriers. The gap between contiguously aggregated carriers due to the nominal channel spacing is allowed.
Spectrum consisting of a contiguous block of spectrum with no sub-block gaps.
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 UE capable of supporting RedCap [IE].
For a UE that supports shared spectrum channel access in wideband operation, a sub-band is the set of RBs within an approximately 20 MHz segment of the channel where the wideband channel is uniformly divided into an integer number of 20 MHz sub-bands. Sub-bands may be separately allocated in uplink and downlink.
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.
The bandwidth of one sub-block.
A frequency gap between two consecutive sub-blocks within an RF bandwidth, where the RF requirements in the gap are based on co-existence for un-coordinated operation.
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.
A UE embedded in a vehicle, permanently connected to an embedded antenna system that radiates externally for NR operating bands.
For a UE that supports shared spectrum channel access, wideband operation refers to operation within a channel larger than 20 MHz in which intra-cell guard bands may be configured to distinguish individual RB-sets
