The present document specifies requirements on UEs supporting a frequency band and inter-band/intra-band CA
configurations that are independent of release. TSG-RAN has agreed that the standardisation of new frequency bands
may be independent of a release, and that the standardisations of new inter-band/intra-band CA configurations also may
be independent of a release for Rel-10 upwards. However, in order to implement a UE that conforms to a particular
release but supports a band of operation or carrier aggregation of particular inter-band/intra-band CA configurations
that is specified in a later release, it is necessary to specify some extra requirements.
For example, Band 19 is contained in the Release 9 specifications. In order to implement a UE conforming to Release 8
but supporting Band 19, it is necessary for the UE to additionally conform to some parts of the Release 9 specifications,
such as the radio frequency and radio resource management requirements for the Band 19.
For another example on carrier aggregations, CA configuration CA_1A-19A is contained in the Release 11
specifications. In order to implement a UE conforming to Release 10 but supporting the CA configuration CA_1A-19A,
it is necessary for the UE to additionally conform to some parts of the Release 11 specifications, such as the radio
frequency and radio resource management requirements for the CA configuration CA_1A-19A.
All frequency bands are fully specified in this release of the specifications. The present document does not contain any
requirements for UEs supporting frequency bands independent of release.
