Introduction In this technical report, the needed modifications to measurement parameters for LTE devices will be studied and applicability of the
24、 existing measurement procedures, e.g. TRP and TRS will be evaluated for LTE devices with multiple receive antennas TDD-LTE and FDD-LTE terminals (as it is expected that the same issues are applicable independent of RAT). As UMTS devices with multiple receive antennas are still needing test methodol
25、ogy, it is easy to extend to this study item contribution to UMTS terminals with, due to similar situation and technical issue. UMTS TRP and TRS test methods should also be updated in the same way. ETSI ETSI TR 137 902 V14.0.0 (2017-04)53GPP TR 37.902 version 14.0.0 Release 141 Scope The present doc
26、ument is a Technical Report of the Study Item for OTA TRP and TRS requirement of LTE terminals, which was approved at TSG RAN #55 2. The report provides the measurement procedure of Over The Air TRP and TRS requirements for LTE terminals. It will make a simple extension to the UE OTA TRP and TRS tes
27、t methods TS34.1143 for LTE UE with multiple receive antennas, without considering all of the aspects associated with spatial channels. The work should utilise the existing environments in TR25.9144. The results of the UE OTA test method with Head and Hand Phantoms study item can be considered later
28、 on once finalized. The report also provides some future extensions and work items after LTE TRP and TRS methods mature. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document. - References are either specific (ide

The rep
40、ort provides the measurement procedure of Over The Air TRP and TRS requirements for LTE terminals. It will make a simple extension to the UE OTA TRP and TRS test methods TR 25.9144 for LTE UE with multiple receive antennas, without considering all of the aspects associated with spatial channels. The
41、 work should utilise the existing environments in TR 25.9144. The results of the UE OTA test method ETSI ETSI TR 137 902 V14.0.0 (2017-04)73GPP TR 37.902 version 14.0.0 Release 14with Head and Hand Phantoms study item can be considered later on once finalized. The report also provides some future ex
42、tensions and work items after LTE TRP and TRS methods mature. 4.1 Scope The measurement procedure explained in this document applies to all LTE devices, which are already satisfied the standard 3GPP LTE RF minimum performance requirements and conformance testing defined in 3GPP TS 36.101: Evolved Un
43、iversal Terrestrial Radio Access (E-UTRA); User Equipment (UE) radio transmission and reception5 and 3GPP TS 36.521-1: Evolved Universal Terrestrial Radio Access (E-UTRA); User Equipment (UE) conformance specification; Radio transmission and reception; Part 1: conformance testing6, respectively. The
44、 testing methodology applies to any 4G LTE handset, USB-dongle and LEE etc, with internal or external antenna. 3GPP TR 25.9144 has done many meaningful studies for evaluating antenna performance of UMTS and GSM terminals. In this document, the majority work will be focus on the LTE TRP and TRS test.
45、 A simple test methodology for LTE devices without channel emulator will be studied. The radio tests considered here are: 1. The measurement of the radiated output power (TRP) 2. The measurement of the radiated sensitivity (TRS) The test procedure described in this document measures the performance
46、of the transmitter and the receiver, including the antenna and also the effects of the user. The purpose of this document is to serve as a standard test procedure for radio performance testing of 4G LTE mobile terminals. It is the intention that this procedure is going to be used by test houses, net
47、work operators, mobile terminal and antenna manufacturers, research institutes etc. The motivation for the development of this document is the lack of standards in this area in 3GPP. During RAN4 #62bis following proposal were agreed. Proposal 1: LTE TRP test method is the same for all LTE UEs indepe
48、ndent of release, including e.g. LTE CA, UL TX Div or UL MIMO capable UEs Proposal 2: LTE TRS test method is the same for all LTE UEs independent of release, including e.g. LTE CA, UL TX Div or UL MIMO capable UEs Proposal 3: In the first phase re-use test environments including phantoms available a
49、lready in TS34.114 for LTE TPR and TRS purposes as well. Once new methods like hand phantom based test environments are defined for UTRA TRP and TRS, then also LTE TRP and TRS testing should be extended to these additional environments. During RAN4 #63 following proposal were agreed. WF 1: Select one channel bandwidth per band for TRP and TRS tests for LTE FDD and TDD. Default channel bandwidth is 10 MHz but another bandwidth can be considered on case by case basis. WF2: For TRS select the reference measurement channel c
