scope:

The present document specifies requirements on UEs supporting a DB-DC-HSDPA, 4C-HSDPA, and 8C-HSDPA configuration that is independent of release. TSG-RAN has agreed that the standardisation of new configurations may be independent of a release. However, in order to implement a UE that conforms to a particular release but supports a configuration that is specified in a later release, it is necessary to specify some extra requirements.

For example, Band I-XI combination for DB-DC-HSDPA (referred to as DB-DC-HSDPA configuration 4 in [2]) is contained in the Release 10 specifications. In order to implement a UE conforming to Release 9 but supporting this configuration, it is necessary for the UE to additionally conform to some parts of the Release 10 specifications, such as the radio frequency and radio resource management requirements for the configuration.

Similarly, 4C-HSDPA configuration I-3 is contained in the Release 11 specification [3]. In order to implement a UE conforming to Release 10, but supporting this configuration, it is necessary for the UE to additionally conform to some parts of the Release 11 specifications.
