Description
Technical field
The present invention relates to the communications field, particularly, relate to system message method of reseptance and device, send window location determining method and device.
Background technology
In Long Term Evolution (Long-Term Evolution abbreviates LTE as) system, system message can be divided into main system message (MIB), System information block 1 (SIB1) and general system message (SI).
Wherein, MIB sends on broadcast channel, and the 40 milliseconds fixing transmission cycle is arranged, and repeats in the #0 subframe of each radio frames of MIB in the transmission cycle to send.System information block 1 (SIB1) sends on DSCH Downlink Shared Channel, and arranged 80 milliseconds fixing dispatching cycle, and SIB1 satisfies the radio frames of SFN%2=0 in dispatching cycle # 5 subframe (subframe is numbered since 0) repeats to send.Other system parameters is included in other the System information block (SIB); For other SIB; At present in the LTE system SIB2～SIB8 etc. has been arranged, the content of system parameters comprised service cell information, district reselecting information, frequently in, frequently between and the adjacent cell information of other RAT etc.
These SIB realize scheduling through being mapped to different system messages, that is to say that SIB defines according to content, and SI are the unit of scheduling.The schedule information of these SI all is included among the SIB1, specifically comprises send window w, dispatching cycle N etc.The order that SI occurs in the schedule information of SIB1 abbreviates dispatching sequence n as.The send window of each SI is all identical, but dispatching cycle maybe be different.The send window of SI is a limited time range; The SIB that is mapped to same SI repeats to send in this time range; But uncertainly in which subframe, send, that is to say, SI need be attempted receiving the decode on each subframe in send window in the terminal.In the LTE system,, generally there is simple multiple relation the dispatching cycle of each SI between the N in order to simplify scheduling scheme; And all be the even number frame, such as 8 frames, 16 frames etc.; This makes certain SFN become the common multiple of some SI,, satisfies the rule of SFN%Ni=0 that is; For convenience, in the following description, these SI are called the SI crowd on the SFN.
The scheduling rule of SI is following: the size of supposing send window is the w sub-frame, and be N the dispatching cycle of certain SI, and the order of its scheduling is n; Then the radio frames and the subframe that begin of the send window of this system message can be used following formulate: SFN%N=COUNT+floor (w* (n-1)/10), subframe=(w* (n-1)) %10, wherein; COUNT is a constant, for example, can be 0 or 8; If COUNT is more than or equal to N, COUNT is modified to COUNT%N so.Can find out that when n=1, subframe=0 that is to say, the send window of the SI of n=1 always begins from the #0 subframe of the radio frames that satisfies SFN%N=COUNT.N sends in send window separately later at the SI of n=1 greater than 1 SI in order continuously successively.For instance; Suppose that one has 7 SIB; Be SIB2, SIB3, SIB4, SIB5, SIB6, SIB7 and SIB8; These SIB are mapped to 7 system messages according to man-to-man mode, i.e. SI-2, SI-3, SI-4, SI-5, SI-6, SI-7 and SI-8, and be respectively 160ms, 320ms, 640ms, 640ms, 1280ms, 1280ms and 1280ms its dispatching cycle.If send window is 20ms, suppose COUNT=0, then the scheduling rule of each SIB is as shown in Figure 1.
As can be seen from Figure 1; SI crowd on SFN=0 comprises SI-2, SI-3, SI-4, SI-5, SI-6, SI-7 and SI-8; The send window of SI-2 begins from the #0 subframe of the SFN of #0, and other SI send in the send window of separately 20ms continuously in order successively.SI crowd on SFN=32 comprises SI-2 and SI-3; SI crowd on SFN=16 and SFN=48 comprises SI-2; SI crowd on SFN=64 comprises SI-2, SI-3, SI-4 and SI-5.
Because be 80 milliseconds the dispatching cycle of SIB1; And scheduling is on fixing radio frames and subframe; Scheduling convenience for other SI; Send in the send window of the SI that SIB1 allows at other, but for fear of on identical subframe, obscuring SIB1 and other SI, the LTE system stipulates that other SI do not allow to send satisfying on the #5 subframe of SFN%2=0.
The span of the send window size of SI is (1ms, 2ms, 5ms, 10ms in the LTE system at present; 15ms, 20ms, 40ms; Spare), wherein, when the send window size is 1ms; According to present scheduling rule, as the SI that is scheduled during more than or equal to 6, the phenomenon of SIB1 and other SI overlapping transmission in identical subframe will appear.With reference to figure 2, the SI crowd on the #0 frame of Fig. 2 begins in continuous subframe, to send from the #0 work song frame of #0 radio frames.The SI-7 that is scheduled is owing to send on the #5 of #0 radio frames subframe, therefore and the transmission of SIB 1 clash.
