Embodiment
The embodiment of the invention provides a kind of system information scheduling method, device and a kind of terminal, can make UE correct receive SU-1, and then can receive complete system information correctly, effectively.For making purpose of the present invention, technical scheme and advantage clearer, the embodiment that develops simultaneously with reference to the accompanying drawings, the present invention is described in more detail.
As shown in Figure 4, the flow chart of the system information scheduling method that provides for the embodiment of the invention one may further comprise the steps:
Step 401: terminal is obtained the schedule information of SU-1, receives the information of complete SU-1 according to described schedule information;
Step 402: terminal is obtained the window information of dynamic dispatching, receives the information of other scheduling unit SU-n, n according to described window information〉1;
Step 403: terminal is obtained the map information of system information block SIB and SU from the information of described SU-1, according to the SIB of described map information indication and the corresponding relation between the SU, obtains all system informations.
In step 401, UE can read the schedule information of SU-1 from Physical Downlink Control Channel (PDCCH, Physical DownlinkControl Channel), also can obtain the schedule information of SU-1 by set form.Specify as follows:
The described schedule information that reads SU-1 from PDCCH specifically can adopt following dual mode:
Mode one, carry an information indicating bit on PDCCH, length is 1 bit, and whether point out has SU-1 to send on certain subframe of back of current subframe.For example, SU-1 is at subframe (subframe) #5, #6, whether the last transmission of #7 so on subframe#5, has 1 bit and indicates and have SU-1 to send that (0 expression does not have on the subframe#6 on the PDCCH, 1 expression has), in like manner for subframe#6, submframe#7.
Mode two, on PDCCH indication SU-1 length, this length is variable, for example indicates with 2 bits, so just can represent 1,2,3,4 subframes.
In addition, described UE can also obtain the schedule information of SU-1 by set form.For example the length of SU-1 is fixed, and such as 3 subframes, like this, UE just can be correct reads SU-1.
In step 402, UE can receive the information of other SU by the window information of dynamic dispatching.At first, in a specific window period, UE judges that the window whether dynamic dispatching is arranged in the described window period exists, if there is not the window of dynamic dispatching to exist, UE does not need to obtain the schedule information relevant with window so; If there is window to exist, network side is notified to UE with the concrete schedule information of window, and these schedule informations can comprise starting position and two parameters of length of window of window, also can only comprise the starting position of window.Specify as follows:
As shown in Figure 5, indicate schematic diagram for the window of embodiment of the invention system information dynamic dispatching.Whether the window of dynamic dispatching exists, and can specifically can realize by following dual mode by the indication of window indication information parameter:
Mode one, window indication information position is placed among the SU-1, length is 1 bit.1 window period interior (fixedly being 80ms) that is illustrated in SU-1 has the window of dynamic dispatching to exist; 0 is illustrated in the window that does not have dynamic dispatching in the window period of SU-1 exists.
Mode two, window indication information position is placed among the MIB, length is 1 bit.1 window period interior (fixedly being 80ms) that is illustrated in SU-1 has the window of dynamic dispatching to exist; 0 is illustrated in the window that does not have dynamic dispatching in the window period of SU-1 exists.
In addition, whether the window that obtain dynamic dispatching by implicit mode of indicating can also be existed.Particularly, because SFN is the sequence number of a radio frames in the LTE system, the length of a radio frames (radio frame) is 10ms, comprises 10 subframes, and the length of each subframe is 1ms.As shown in Figure 5, for example the scheduling window of SU supposes it is SFN mod8=0 in certain location, in the time of SFN=159, does not satisfy SFN mod 8=0 so, and UE just knows on this radio frames does not so have scheduling window; In the time of SFN=160, satisfy SFN mod 8=0, UE just knows on this radio frames so scheduling window.Therefore, if adopt this mode just can not need to indicate the schedule information of UE window.
After defining the window existence of dynamic dispatching by the way, need provide window starting position indication information, allow UE know the position that window begins.As shown in Figure 6, if three radio frames are arranged, SFN is respectively 159,160,161, sends SU-1 on 160, and the indication of window starting position can have following three kinds of modes:
Mode one, as shown in Figure 7, the window starting position of dynamic dispatching can be fixed on the subframe starting position of SU-1, and UE does not need extra information to obtain the window starting position of dynamic dispatching.
Mode two, as shown in Figure 8, there is the side-play amount (offset) of certain subframe in the subframe starting position of the window starting position of dynamic dispatching and SU-1 scheduling, and the position of this side-play amount indication is more flexible, can according to circumstances be configured among the SU-1.For the FDD system, if be not suitable for transmitting system information in several subframes of certain section moment SU-1 back, it is several subframes that described side-play amount can be set so; For the TDD system,, by being set, described side-play amount can allow window certain subframe so from the SU-1 back because several subframes of SU-1 back are used in the transmission upstream data under some occasion.Special, if described side-play amount is 0, the window starting position is exactly the subframe starting position near the SU-1 scheduling so.
Mode three, as shown in Figure 9, there is a fixing side-play amount in the subframe starting position of the window starting position of dynamic dispatching and SU-1 scheduling, for example SU-1 is fixed on subframe#5 to go up scheduling, the window starting position of dynamic dispatching can be set to subframe#7 so, i.e. 2 subframes after the SU-1.This indicating positions is more fixing, and UE does not need extra information to obtain the window starting position of dynamic dispatching.
After UE began to read from window, network side can also be notified the UE length of window, so that can allow UE stop to read of window.As shown in figure 10, in SU-1, indicating the schematic diagram of length of window.Is example with SU-1 and a side-play amount as the window starting position, if the length of window is 12 subframes among the SU-1, and the side-play amount of window is 2 subframes, UE just can calculate the position that window finishes so, and promptly 12 subframe rear hatches after window begins finish or 15 subframe rear hatches end after SU-1 begins.
In addition, can also utilize the length of the implicit indication window of mode of saltus step Hopping.As shown in figure 11, supposing to have three SU, is respectively SU-1, SU-2, SU-3, the cycle is respectively 80ms, 160ms, 320ms, the cycle of the window of dynamic dispatching is 80ms, so as shown in figure 11, and from SFN=160, the length of window is 4 subframes, 1 subframe, 2 subframes, 1 subframe, 4 subframes, 1 subframe ... therefrom as can be seen, the length variations of window are regular saltus steps, and its period of change is 320ms (Cycle Length of maximum SU).Thereby, if adopt the mode of saltus step Hopping, UE can just calculate the length of window according to this rule so, and for example on SFN mod 32=0, length of window is 4 subframes, on SFN mod 32=8, length of window is 1 subframe, and on SFN mod 32=16, length of window is 2 subframes, on SFNmod 32=24, length of window is 1 subframe.
In step 403, UE obtains the SIB information that each SU comprises by the map information of SIB and SU.Because at present dispatching cycle and the position of SU-1 are fixed, the content that comprises is SIB-1 and SB, thereby content also fixes, so the map information of SIB and SU does not comprise SU-1 and SIB-1.
The number of supposing SU is N, and N=3 is expressed as SU-2, SU-3, SU-4.
The number of SIB is M, and M=7 is expressed as SIB-2, SIB-3, SIB-4, SIB-5, SIB-6, SIB-7, SIB-8.
The mapping relations of SIB and SU are: SU-2 comprises SIB-2, SIB-3; SU-3 comprises SIB-4, SIB-5, SIB-6; SU-4 comprises SIB-7, SIB-8.
Can realize the expression of the map information of SIB and SU by following three kinds of modes, be specially:
Mode one, represent by the mode of bitmap.
State as shown in table 1, that each SU indicates SIB-2～SIB-7 with 7 bits, 1 expression SIB are in SU, and 0 expression SIB is not in SU.

| SU-3 | 0 | 0 | 1 | 1 | 1 | 0 | 0 |
| SU-4 | 0 | 0 | 0 | 0 | 0 | 1 | 1 |
By calculating as can be known, the mode of pass-through mode one bitmap represents that the expense of the map information of SIB and SU is: 3
*7=21bit.
Mode two, represent by the mode of enumerating.
As shown in table 2, represent all SU with 2 bits, for example: 00 expression SU-1,01 expression SU-2,10 expression SU-3,11 expression SU-4.There is the information of this SIB place SU in each SIB.
Table 2
| SIB-2 | SIB-3 | SIB-4 | SIB-5 | SIB-6 | SIB-7 | SIB-8 | |
| SU type (2bit) | 01 | 01 | 10 | 10 | 10 | 11 | 11 |
By calculating as can be known, the mode that pass-through mode two is enumerated represents that the expense of the map information of SIB and SU is: 2*7=14bit.
Mode three, the mode of enumerating by another kind are represented.
As shown in table 3, represent all SU with 2 bits, for example: 00 expression SU-1,01 expression SU-2,10 expression SU-3,11 expression SU-4.Represent all SIB with 3 bits, for example: 000 expression SIB-1,001 expression SIB-2,010 expression SIB-3,011 expression SIB-4,100 expression SIB-5,101 expression SIB-6,110 expression SIB-7,111 expression SIB-8, each SU enumerates the SIB that this SU comprises.
Table 3
| SU-2 | 001，010 |
| SU-3 | 011，100，101 |
| SU-4 | 110，111 |
By calculating as can be known, the mode that pass-through mode three is enumerated represents that the expense of the map information of SIB and SU is: 2*3+3*7=27bit.
