NOTE:        As the RRC message which activates the integrity protection function is itself integrity protected with the configuration included in this RRC message, this message needs first be decoded by RRC before the integrity protection verification could be performed for the PDU in which the message was received.
麻烦问下这句话怎么理解，在完整性保护鉴定前信息怎么可能被RRC解码，不是很了解。接收端，PDCP应该在下层啊？
