Table 1 indicates the application example 1 that system information updates

RNTI value	Indicate content
		RNTI1	There is no updating for system information
RNTI2	MIB updates

RNTI3	SIB1 updates
		RNTI4	SIB2 updates
RNTI5	MIB and SIB1 update
		RNTI6	MIB and SIB2 update
RNTI7	SIB1 and SIB2 update
		RNTI8	MIB, SIB1 and SIB2 update

As known from Table 1, compare first way, and fifth procedure can not only indicate that system information updates, also It can indicate that specifically which or which system information updates.It should be noted that N can be corresponding equal to 0 It is that there is no more news using RNTI1 instruction system information.

6th kind of mode: M system information is indicated by scrambled RNTI on the PDSCH of carrying SIB1, SIB2 or SI In N number of system information update, wherein M, N are positive integers, and M is more than or equal to 2, N and is less than or equal to M.6th kind of mode and the Five kinds of modes are similar, and and will not be described here in detail.
