NOTE 1: RRC messages in step 1 and 2 use SRB0, all the subsequent messages use SRB1. Messages in steps 7/7a are integrity protected. From step 8 on, all the messages are integrity protected and ciphered. NOTE 2: For signalling only connection, step 8 is skipped since SRB2 and DRBs...
Messages in steps 7/7a are integrity protected. From step 8 on, all the messages are integrity protected and ciphered. NOTE 2:For signalling only connection, step 8 is skipped since SRB2 and DRBs are not setup. RRC_INACTIVE到RRC_CONNECTED转换 1.The UE resumes from RRC_INACTIVE, providing...
Higher extensibility:RRC messages can be extended easily to accommodate additional control information, for example, for enhancements in future releases of LTE. Secured transmission:Integrity protection and ciphering of an RRC message carried on the DCCH can be provided by the PDCP layer. Neither integ...
Moreover, we make two aspects of modifications to the existing LTE protocol. Firstly, some RRC messages and corresponding information elements (IE) are added to carry the cognitive and decision information. Then, we add some crucial procedures, such as configuring spectrum sensing, reporting the ...
