32、he study item on MIMO OTA, which was approved at TSG RAN#43 2. The scope of the SI is to define a 3GPP methodology for measuring the radiated performance of multiple antenna reception and MIMO receivers in the UE. The test methodology should be relevant for HSPA and LTE technologies, with particular
33、 focus on handheld devices and devices embedded in laptop computers. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document. - References are either specific (identified by date of publication, edition number, vers

46、 devices. 3GPP already defined conducted tests for MIMO and multiple antenna receivers (type 1 and type 3 in TS25.101 for HSPA demodulation), but it is clear that the ability to duplicate these gains in the field is highly dependent on the performance of the receive-antenna system.

47、976 V14.0.0 (2017-04)83GPP TR 37.976 version 14.0.0 Release 14At TSG RAN#41, it was indicated that there is a need for a test methodology to be created with the aim of measuring and verifying the radiated performance of multi-antenna and MIMO receiver in UEs for both HSPA and LTE devices. As an outc
48、ome of the discussion, an LS was sent to COST 2100 SWG2.2 and CTIA ERP to ask them for feedback on their plans/ongoing work in this area, and also the timescales for which such work could be completed to define such a methodology, with particular focus on handheld devices and devices embedded in lap
49、top computers. Since then, feedback from COST 2100 and CTIA has suggested they are happy to work on this topic. However given that 3GPP is the customer for this work as well as being a potential contributor, it is important to aim for commonly-accepted measurement and test methodology to be used across the industry. 4.2 Study item objective The high level objective of this study item is to define a 3GPP methodology for measuring the radiated performance of multiple antenna reception and MIMO receivers in the UE. The test methodology sh
