The present document specifies requirements on MSs supporting Downlink Advanced Receiver Performance (DARP) that are independent of release. TSG GERAN has agreed that the standardisation of DARP be independent of a release. However, in order to implement an MS that conforms to a particular release but supports DARP, which is specified in a later release, it is necessary to specify some extra requirements.
DARP - phase II is contained in the Release 7 specifications. In order to implement an MS conforming to Release 5 but supporting DARP - phase II, it is necessary for the MS to additionally conform to some parts of the Release 7 specifications, such as the radio frequency requirements for DARP and some signalling extensions relating to the MS Classmark and radio access capabilities.
The following documents contain provisions which, through reference in this text, constitute provisions of the present document.
References are either specific (identified by date of publication, edition number, version number, etc.) or non specific.
For a specific reference, subsequent revisions do not apply.
For a non-specific reference, the latest version applies. In the case of a reference to a 3GPP document (including a GSM document), a non-specific reference implicitly refers to the latest version of that document in the same Release as the present document.

Unless listed below, all definitions and abbreviations used in the present document are listed in documents referenced in clause 2
For the purposes of the present document, the following abbreviations apply:
Downlink Advanced Receiver Performance
Single Antenna Interference Cancellation, also known as DARP - phase I
Mobile Station Receive Diversity, also known as DARP - phase II
MSs that conform to Release 5 and support DARP - phase II shall support the following requirements in Release 7.
