Such as in the figure 7, each row indicate that 1 time slot, 1 subframe include 2 time slots, and 1 system-frame includes 10 sons Frame, time slot of the subframe out of 0 incremental number (#0, #1 ... #9), a subframe in a system-frame is from 0 incremental number (# 0, #1).The period of reserved resource is 20ms, and time offset is the 5th time slot and the 13rd time slot in the period.When receiving this After domain information, there is reserved resource in the time slot #0 of the time slot #0 and subframe #6 of the subframe #2 of system-frame #0 known to terminal T100, The time slot #0 of the time slot #0 and subframe #6 of the subframe #2 of system-frame #2 in next cycle have reserved resource.

Skilled person will appreciate that time offset can be there are many expression way.Time offset in above-mentioned example It can also be expressed as the 1st time slot of the 3rd subframe in the period and the 1st time slot of the 7th subframe, or can be with table State the time slot #0 of the time slot #0 and subframe #6 for subframe #2 in the period.

As an example, as shown in table 4, may include following content in the RRC signaling of S400A.

Table 4

Domain (field)	Explanation
		Period	If not filling in and default cycles may be used
System Frame Number	Filling as needed
		Subframe numbers	Filling as needed
Timeslot number	Filling as needed
		Symbol number	Filling as needed

Such as：Period is 20ms, System Frame Number #1, then it represents that second system-frame in per 20ms is reserved resource institute The time domain accounted for.Again for example：Period is 10ms, subframe numbers #2, then it represents that the third subframe per 10ms is shared by reserved resource Time domain.

Optionally, after the parts S400A execute, S403 can not be performed.
