With in different ways.
With reference to Fig. 7, a frame is 10ms, when the SS burst set period is 20ms, due to SS burst set
Every 2 frames occur once, and therefore, the last 1bit of SFN is always 0.So can be distinguished by last position of SFN when week
It is 20ms or bigger period when phase is greater than 10ms.It is then the week of 20ms if last position A=11, SFN is 0
Phase.Work as A=11, it is then the period greater than 20ms that last position SFN, which is 1, such as 40,80,160ms period.
Therefore, when the SS burst set period is 20ms, most with period and field joint instructions and SFN
Latter position indicates the number or time index of SS block.
With reference to Fig. 7, a frame is 10ms, when the SS burst set period is 40ms, due to SS burst set
Every 4 frames just occur once, and therefore, inverse the 2nd of SFN is always 0.So can be distinguished by the inverse of SFN the 2nd
It is 40ms or bigger period when being greater than 20ms in the period.If last position A=11, SFN is the inverse of 1, SFN
2nd is 0, then is the period of 40ms.If inverse the 2nd that last position A=11, SFN is 1, SFN is 1, then for greater than
The period of 40ms, such as 80,160ms period.
Therefore, when the SS burst set period is 40ms, most with period and field joint instructions and SFN
2 indicate the number or time index of SS block afterwards.
With reference to Fig. 7, a frame is 10ms, when the SS burst set period is 80ms, due to SS burst set
Every 8 frames just occur once, and therefore, inverse the 3rd of SFN is always 0.So can be distinguished by the inverse of SFN the 3rd
It is 80ms or bigger period when being greater than 40ms in the period.If last position A=11, SFN is the inverse of 1, SFN
2nd be 1, SFN inverse the 3rd is 0, then is the period of 80ms.If last position A=11, SFN is the inverse of 1, SFN
2nd be 1, SFN inverse the 3rd is 1, then is the period greater than 80ms, such as the 160ms period.
Therefore, when the SS burst set period is 80ms, most with period and field joint instructions and SFN
3 indicate the number or time index of SS block afterwards.
Similarly, when the SS burst set period is 160ms, most with period and field joint instructions and SFN
4 indicate the number or time index of SS block afterwards.
And so on, the period greater than 80ms can be indicated by SFN.It is specifically shown in the following table 1 and table 2.
