Section: 6.2.2A UE maximum output power for CA
Content: The following UE Power Classes define the maximum output power for any transmission bandwidth within the aggregated channel bandwidth. The maximum output power is measured as the sum of the maximum output power at each UE antenna connector. The period of measurement shall be at least as defined in Table 6.2.2A-0a. Table 6.2.2A-0a: Measurement period for UE maximum output power for CA For inter-band carrier aggregation with one uplink component carrier assigned to one E-UTRA band the requirements in subclause 6.2.2 apply. For inter-band carrier aggregation with two uplink contiguous component carrier assigned to one E-UTRA band the requirements specified in Table 6.2.2A-1 apply for that band. For inter-band carrier aggregation with one uplink component carrier assigned to one E-UTRA band in Band 38, 40, 41 or 42, the requirements for power class 2 are not applicable and the corresponding requirements for a power class 3 UE shall apply. For inter-band carrier aggregation with one uplink component carrier assigned to one E-UTRA band in Band 3, 20, 28, or 31, the requirements for power class 1 are not applicable and the corresponding requirements for a power class 3 UE shall apply. For inter-band carrier aggregation with uplink assigned to two E-UTRA bands, UE maximum output power shall be measured over all component carriers from different bands. If each band has separate antenna connectors, maximum output power is measured as the sum of maximum output power at each UE antenna connector. The maximum output power is specified in Table 6.2.2A-0. For E-UTRA CA bands including an uplink LAA Scell in Band 46, the UE shall meet the following additional requirements for transmission within the frequency ranges 5150-5350 MHz and 5470-5725 MHz: - a maximum mean power density of 10 dBm in any 1 MHz band when the network signaling value NS_28 or NS_29 is indicated in the LAA Scell; - a maximum mean power density of 11 dBm in any 1 MHz band when the network signaling value NS_30 is indicated in the LAA Scell; the following additional requirements for transmission within the frequency range 5230-5250 MHz: - a maximum mean power density of 4 dBm in any 1 MHz band when the network signaling value NS_31 is indicated in the LAA Scell; the following additional requirements for transmission within the frequency ranges 5150-5230 MHz, 5250-5350 MHz, 5470-5725 MHz and 5725-5850 MHz: - a maximum mean power density of 10 dBm in any 1 MHz band when the network signaling value NS_31 is indicated in the LAA Scell; where the said network signaling values are specified in clause 6.2.4. Table 6.2.2A-0: UE Power Class for uplink interband CA (two bands) For uplink intra-band contiguous carrier aggregation the maximum output power is specified in Table 6.2.2A-1. For downlink intra-band contiguous carrier aggregation with a single uplink component carrier configured in the E-UTRA band, the maximum output power is specified in Table 6.2.2-1. For a power class 2 capable UE operating with intra-band uplink contiguous CA bandwidth class C on Band 41, when an IE P-max as defined in TS 36.331[ Evolved Universal Terrestrial Radio Access (E-UTRA); Radio Resource Control (RRC); Protocol specification ]  [7] of 23 dBm or lower is indicated in the cell or if the uplink/downlink configuration is 0 or 6, the requirements for power class 2 are not applicable, and the corresponding requirements for a power class 3 UE shall apply. Table 6.2.2A-1: CA UE Power Class for intraband contiguous CA For intra-band non-contiguous carrier aggregation with one uplink carrier on the PCC, the requirements in subclause 6.2.2 apply. For intra-band non-contiguous carrier aggregation with two uplink carriers the maximum output power is specified in Table 6.2.2A-2. Table 6.2.2A-2: UE Power Class for intraband non-contiguous CA
