6.3.3 Transmit OFF power
36.521-13GPPEvolved Universal Terrestrial Radio Access (E-UTRA)Part 1: Conformance testingRadio transmission and receptionRelease 17TSUser Equipment (UE) conformance specification
6.3.3.1 Test purpose
To verify that the UE transmit OFF power is lower than the value specified in the test requirement.
6.3.3.2 Test applicability
The requirements of this test apply in test cases 6.3.4.1 General ON/OFF time mask and 6.3.4.2 PRACH and SRS time mask to all types of E-UTRA UE release 8 and forward.
6.3.3.3 Minimum conformance requirement
The transmit OFF power is defined as the mean power in a duration of at least one sub-frame (1ms) excluding any transient periods. The requirement for the transmit OFF power shall not exceed the values specified in Table 6.3.3.3-1.

The normative reference for this requirement is TS 36.101 [2] clause 6.3.3.
Transmit OFF power is defined as the mean power when the transmitter is OFF. The transmitter is considered to be OFF when the UE is not allowed to transmit or during periods when the UE is not transmitting a sub-frame. During DTX and measurements gaps, the UE is not considered to be OFF.
An excess transmit OFF power potentially increases the Rise Over Thermal (RoT) and therefore reduces the cell coverage area for other UEs
6.3.3.4 Test description
This test is covered by clause 6.3.4.1 General ON/OFF time mask and 6.3.4.2 PRACH and SRS time mask.
6.3.3.5 Test requirement
The requirement for the transmit OFF power shall not exceed the values specified in Table 6.3.3.5-1.
