3 Definitions of terms, symbols and abbreviations p. 7
3.1 Terms p. 7
For the purposes of the present document, the terms given in TR 21.905 and the following apply. A term defined in the present document takes precedence over the definition of the same term, if any, in TR 21.905.
Browsing mode usage:
This mode corresponds to "data" mode, the device is tested via hand-only phantoms.
Primary mechanical mode:
The mode that is most often used for a specific user scenario. Every terminal has at least one primary mechanical mode, if multiple modes are supported, different primary mechanical modes may be applicable for different user scenarios, e.g., different primary mechanical modes for Browsing mode usage and Talk mode usage for the same UE.
Talk mode usage:
This mode corresponds to "talk" mode, the device is tested via head&hand phantoms.
3.2 Symbols p. 8
For the purposes of the present document, the following symbols apply:
TRPaverage
The average measured total radiated power of low, mid and high channel. When hand phantom is involved, the average is performed with low, mid and high channel from both hand left and hand right.
TRSaverage
The average measured total radiated sensitivity of low, mid and high channel. When hand phantom is involved, the average is performed with low, mid and high channel from both hand left and hand right.
3.3 Abbreviations p. 8

4 General p. 8
4.1 Relationship between minimum requirements and test requirements p. 8
The Minimum Requirements given in this specification make no allowance for measurement uncertainty. The test specification in RAN5 will define final test tolerances for FR1 TRP TRS. The test tolerances are used to relax the minimum requirements in this specification to create test requirements.
4.2 Applicability of minimum requirements p. 8
4.2.1 General p. 8
The minimum requirements apply only to the corresponding primary mechanical mode of UE in the environmental conditions specified in Annex C.4.2.2.
4.2.2 UE mechanical modes p. 9
The mechanical modes of a device under test (DUT) are declared by the manufacturer. A DUT shall have at least one mechanical mode. If only one mode is supported, then this is defined as the primary. If multiple modes are supported, the manufacturer can declare different primary mechanical modes applicable for different user scenarios, e.g., different primary mechanical mode for Browsing mode usage and Talk mode usage for the same UE.
4.3 Applicability rules for testing of FR1 SA and NSA UEs p. 9
The applicability and test coverage rules for Non-Standalone (NSA) only capable devices shall include the following:
- For each NR band supported by the device, test the UE in EN-DC mode using any one example configuration containing that NR band or configuration declaration decision tree as per recommended TRP/TRS test procedures in this specification.
- For each NR band in a device, test the UE in Standalone Mode as per the TRP/TRS test procedures in this specification.
- This shall also fulfil coverage for all EN-DC FR1 minimum performance requirements for that NR band and need not be retested in EN-DC mode.
4.4 Applicability rules for testing of power class capability of UEs p. 9
The applicability and test coverage rules for PC2 and PC3 UEs shall include the following:
- For UEs that support PC2 in a given band: verify the requirement only with PC2 configuration
- For UEs that only support PC3 in a given band: verify the requirement with PC3 configuration
