The contents of the present document are subject to continuing work within the TSG and may c
38、hange following formal TSG approval. Should the TSG modify the contents of the present document, it will be re-released by the TSG with an identifying change of release date and an increase in version number as follows: Version x.y.z where: x the first digit: 1 presented to TSG for information; 2 pr
39、esented to TSG for approval; 3 or greater indicates TSG approved document under change control. y the second digit is incremented for all changes of substance, i.e. technical enhancements, corrections, updates, etc. z the third digit is incremented when editorial only changes have been incorporated

ETSI ETSI TR 125 922 V7.1.0 (2007-03) 8 3GPP TR 25.922 version 7.1.0 Release 7 1 Scope The present document shall describe RRM strategies supported by UTRAN specifications and typical algorithms. This report is a release independent report. This means that the latest release applica
41、ble to 3GPP is the reference that this TR is defined upon, and contains information on all previous releases. Actual release where a given example applies is indicated in the relevant section. 2 References The following documents contain provisions which, through reference in this text, constitute p
42、rovisions 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 referen
43、ce 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. 1 3GPP Homepage: www.3GPP.org. 2 3GPP TS 25.212: “Multiplexing and channel coding“. 3 3GPP TS 25.215: “Physical layer Measu
