Section: 6.3.4 ON/OFF time mask 6.3.4.1 General ON/OFF time mask
Content: The General ON/OFF time mask defines the observation period between Transmit OFF and ON power and between Transmit ON and OFF power. ON/OFF scenarios include; the beginning or end of DTX, measurement gap, contiguous, and non contiguous transmission The OFF power measurement period is defined in a duration of at least one subframe, or one slot or one subslot for sTTI, excluding any transient periods. The ON power is defined as the mean power over one subframe, or one slot or one subslot for sTTI, excluding any transient period. There are no additional requirements on UE transmit power beyond that which is required in subclause 6.2.2 and subclause 6.6.2.3 The transient period length shall be no longer than the specified value in Table 6.3.4.1-1. Table 6.3.4.1-1: Transient period length depending on transmission length Figure 6.3.4.1-1: General ON/OFF time mask for subframe TTI and for Frame Structure Type 1 and Frame Structure Type 2 For Frame Structure Type 3 the general ON/OFF mask is specified in 6.3.4.1-1A with the PUSCH starting position modified by relative to the start of the sub-frame as indicated in the associated DCI, where and the basic time unit are specified in [4]. At the end of the sub-frame and with denoting the duration of the last SC-FDMA symbol when the bit indicating the PUSCH ending symbol in the associated DCI has value ‘0’ and ‘1’ as specified in [5], respectively; the OFF power requirement applies 5 s after the end of the last symbol transmitted.
