The contents of the prese
33、nt document are subject to continuing work within the TSG and may change 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
34、 where: x the first digit: 1 presented to TSG for information; 2 presented 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
35、 is incremented when editorial only changes have been incorporated in the document. ETSI ETSI TS 125 301 V15.0.0 (2018-07)63GPP TS 25.301 version 15.0.0 Release 151 Scope The present document shall provide an overview and overall description of the UE-UTRAN radio interface protocol architecture as a
