8.1 Minimum requirement for roaming bands for handheld UE
8.1.1 Free Space
Requirements in this section are stated for the free space configuration, are applicable to handheld devices, and are not applicable to wrist-worn devices.
For the reference MPAC methodology and the harmonized RTS methodology defined in [7], the average TRMS of free space data mode portrait (FS DMP), free space data mode landscape (FSDML), and free space data mode screen up (FS DMSU), as defined in Annex E of TR 37.977 [7], when measured at the mid channel shall be lower than the average TRMS requirements specified in subclauses 8.1.1.1 and 8.1.1.2. The averaging shall be done in linear scale for the TRMS results at these DUT positions. Two average TRMS quantities are calculated from sensitivity measurements at 70% and 95% throughput, respectively. Average TRMS requirement are shown in the column “Average, 70” and “Average, 95” on the requirement tables.
Where
Such that MODE is one of {FS_DMP, FS_DML, FS_DMSU}, x is one of {70, 95}, and {PMODE,x,0, …, PMODE,x,11} are the measured sensitivity values at each azimuth position.
For the reference MPAC methodology and the harmonized RTS methodology defined in [7], if 1 azimuth position does not result in a defined measured sensitivity at 70% or 95% throughput, SMODE,70 or SMODE,95 are calculated using the 11 measured sensitivities and the maximum downlink RS-EPRE PRS-EPRE-MAX (substitution approach) for the one missing result. If 2 azimuth positions do not result in a defined measured sensitivity at 95% throughput, SMODE,95 is calculated using the 10 measured sensitivities and PRS-EPRE-MAX for the two missing results. If more azimuth positions result in undefined values for measured sensitivity at the 70% and/or 95% throughput, then the TRMS requirement for the corresponding throughput levels has not been met by such a device. PRS-EPRE-MAX is defined as -80 dBm/15 kHz and is the maximum downlink RS-EPRE supported by the test system.
8.1.1.1 E-UTRA FDD
Handheld UE TRMS minimum performance requirements for E-UTRA FDD in free space and the primary mechanical mode for 70% and 95% DL throughput with the reference measurement channel defined in Clause 7 of TR 37.977 [7] are defined in Table 8.1.1.1-1.

NOTE 1: Restricted to E-UTRA operation when carrier aggregation is configured. The downlink operating band is paired with the uplink operating band (external) of the carrier aggregation configuration that is supporting the configured Pcell.
