Section: 6.3.4.2.2 SRS time mask
Content: In the case a single SRS transmission, the ON power is defined as the mean power over the symbol duration excluding any transient period; Figure 6.3.4.2.2-1 and Figure 6.3.4.2.2-1A. In the case a dual SRS transmission, the ON power is defined as the mean power for each symbol duration excluding any transient period. Figure 6.3.4.2.2-2 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 Figure 6.3.4.2.2-1: Single SRS time mask for Frame Structure Type 1 and Frame Structure Type 2 For Frame Structure Type 3 and single SRS transmission, the SRS time mask is specified in 6.3.4.2-2A; the OFF power requirement applies [5] s after the end of the SRS symbol. Figure 6.3.4.2.2-1A: Single SRS time mask for Frame Structure Type 3 Figure .2.2-2: Dual SRS time mask for the case of UpPTS transmissions For SRS transmission mapped to two or more OFDM symbols the ON power is defined as the mean power for each symbol duration excluding any transient period. For consecutive SRS transmissions without power change, Figure .2.2-3 applies. Figure .2.2-3: Consecutive SRS time mask for the case when no power change is required When power change between consecutive SRS transmissions is required, then Figure .2.2-4 and Figure .2.2-5 apply. Figure .2.2-4: Consecutive SRS time mask for the case when power change is required Figure .2.2-5: Time mask for SRS antenna switching The above transient period applies to all the transmit CCs in CA with the CC sounding SRS. UE RF requirements do not apply during this transient period.
