Introduction In this technical report, the needed modifications to measurement parameters for LTE devices will be studied and applicability of the existing measurement
24、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 methodology, it is easy to ext
25、end 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 V13.0.0 (2016-01)53GPP TR 37.902 version 13.0.0 Release 131 Scope The present document is a Technical R
26、eport 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 test methods TS34.1143 fo
27、r 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 on once finalized. Th

40、ement 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 work should utilise th
41、e existing environments in TR 25.9144.

The report also provides some future extensions and work items
42、 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 Universal Terrestrial Rad
43、io 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 testing methodology ap
44、plies 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. A simple test methodol
45、ogy 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 of the transmitter and
46、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, network operators, mobile
47、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 independent of release, inclu
48、ding 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 already in TS34.114 for
49、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 configuration for LTE FD
