5GNRUE最大发射功率

　　5G NG gNB侧控制UE最大发射功率的三个参数：
　　p-Max
　　p-NR-FR1
　　p-UE-FR1
　　备注：
　　1. gNB侧使用这三个参数一起控制UE的最大发射功率，所以协议描述其中一个参数的时候，会附加描述另外两个参数；
　　2. p-Max是小区级参数，在SIB1中下发；
　　3. p-NR-FR1和p-UE-FR1是UE级参数，在MSG4和重配消息中下发；
　　4. p-UE-FR1仅涉及NSA场景；
　　p-Max(38.331)p-Max(38.331)
　　Maximum transmit power allowed in this serving cell. The maximum transmit power that the UE may use on this serving cell may be additionally limited
　　by  p-NR-FR1  (configured for the cell group)  and
　　by   p-UE-FR1   (configured total for all serving cells operating on FR1)  .
　　If absent, the UE applies the maximum power according to TS 38.101-1 [15] in case of an FR1 cell or TS 38.101-2 [39] in case of an FR2 cell. In this release of the specification, if p-Max is present on a carrier frequency in FR2, the UE shall ignore the field and applies the maximum power according to TS 38.101-2 [39]. Value in dBm.
　　p-NR-FR1, p-UE-FR1(38.331)p-NR-FR1(38.331)
　　The maximum total transmit power to be used by the UE in this NR cell group across all serving cells in frequency range 1 (FR1). The maximum transmit power that the UE may use may be additionally limited
　　by  p-Max  (configured in  FrequencyInfoUL )  and
　　by  p-UE-FR1  (configured total for all serving cells operating on FR1) .p-UE-FR1
　　The maximum total transmit power to be used by the UE across all serving cells in frequency range 1 (FR1) across all cell groups. The maximum transmit power that the UE may use may be additionally limited
　　by  p-Max  (configured in  FrequencyInfoUL )  and
　　by  p-NR-FR1  (configured for the cell group) .
　　maxUplinkDutyCycle-PC2-FR1 (38.306)maxUplinkDutyCycle-PC2-FR1   (38.306)
　　Indicates the maximum percentage of symbols during a certain evaluation period that can be scheduled for uplink transmission so as to ensure compliance with applicable electromagnetic energy absorption requirements provided by regulatory bodies. This field is only applicable for FR1 power class 2 UE as specified in clause 6.2.1 of TS 38.101-1 [2]  . If the field is absent, 50% shall be applied. Value n60 corresponds to 60%, value n70 corresponds to 70% and so on. This capability is not applicable to IAB-MT.maxUplinkDutyCycle-FR2
　　Indicates the maximum percentage of symbols during 1s that can be scheduled for uplink transmission at the UE maximum transmission power, so as to ensure compliance with applicable electromagnetic power density exposure requirements provided by regulatory bodies. This field is applicable for all power classes UE in FR2 as specified in TS 38.101-2 [3]. Value n15 corresponds to 15%, value n20 corresponds to 20% and so on. If the field is absent or the percentage of uplink symbols transmitted within any 1s evaluation period is larger than maxUplinkDutyCycle-FR2, the UE behaviour is specified in TS 38.101-2 [3]. This capability is not applicable to IAB-MT.
