ETSI ETSI TR 125 914 V14.0.0 (2017-04)83GPP TR 25.914 version 14.0.0 Release 141 Scope The present document describes the methods to be used in order to assess the radio performances of the 3G us
47、er equipment/mobile stations (UE/MS) in active mode in both the up- and the downlink. The test procedure is based on the test method developed as a result of COST 273 Sub-Working Group (SWG) 2.2 members contributions and the first draft was published in 1. Background work has also been made in the f
