Universal Terrestrial Radio Access (UTRA) and Evolved UTRA (E-UTRA); User Equipment (UE) Over The Air (OTA) performance; Conformance testing
The present document describes the test procedure for the radiated performances measurements of the user equipment (UE).
The handheld UE measurement procedures explained in this document are defined for roaming bands for the speech mode position (beside the head and beside the head and hand) and hand phantom browsing mode position. Laptop mounted equipment (LME) measurement procedures are defined for roaming bands for the data mode transfer position (laptop ground plane phantom). Laptop embedded equipment (LEE) measurement procedures are defined for roaming bands for the data mode transfer position (free space).
The browsing mode position explained in this document applies when the UE is held in hand, but not pressed against ear (such as web browsing and navigation).
The data mode transfer position (free space) explained in this document applies when the UE is used away from the user’s head. Free space measurements are applicable to devices used in the data mode transfer position that consist of the laptop mounted equipment (LME) plug-in UEs and laptop embedded equipment (LEE) UEs.
All bands are potential roaming bands, and the requirements for roaming bands shall therefore be fulfilled for all bands supported by a UE.
Radiated performance of multiple-antenna receivers for handheld UE is defined for roaming bands in free space configuration.
Recommended performance values for operating bands (Annex I) are however included in this specification for information. It should be recognised that the ability to meet the recommended performance values depends on the number of frequency bands supported by the UE.
The radiated radio tests considered here are:
1. The measurement of the Total Radiated Power (TRP)
2. The measurement of the Total Radiated Sensitivity (TRS)
3. The measurement of Total Radiated Multi-antenna Sensitivity (TRMS)
The test procedure described in this document measures the performance of the transmitter and the receiver, including the antenna and also the effects of the user.
