UEs are not required to support the reception of multiple occurrences of the same system information block type within
one SYSTEM INFORMATION message.是8.1.1.1.3中的一句话，下面是8.1.1.1.4中的一部分：
8.1.1.1.4 Re-assembly of segments
The RRC layer in the UE shall perform re-assembly of segments. All segments belonging to the same master
information block, scheduling block or system information block shall be assembled in ascending order with respect to
the segment index. When all segments of the master information block, scheduling block or a system information block
have been received, the UE shall perform decoding of the complete master information block, scheduling block or
system information block. For System Information Block types 15.2, 15.3 and 16, which may have multiple occurrences, each occurrence shall be re-assembled independently. 既然不要求UE支持系统信息中出现多个SIB块，那么SIB15.2、SIB15.3和SIB16出现多次怎么处理？？？我觉得协议这里很矛盾！
