And last downlink subframe SF4 comprises 5 OFDM symbol and last idle characters S5.Idle characters S5 is used as the TTG distinguishing down link (DL) and up link (UL).
Present superframe header (SFH) will be described.
In BWA, SFH is used for the system information of the key of the communication between terminal and base station to terminal transmission.As shown in Figure 1, SFH is positioned at the first subframe place of single superframe.SFH can comprise the main SFH(P-SFH of the control information of sending for receiving SFH) and send the auxiliary SFH(S-SFH of critical system information of such as Web portal and so on).
According to the type of system information or the transmission frequency of system information, S-SFH can comprise multiple attached bag (SP), and preferably, S-SFH comprises 3 SP(SP1, SP2 and SP3).
P-SFH sends during each superframe, and comprises 4 LSB information of Hyper Frame Number (SFN) and the information relevant to S-SFH.The information relevant to S-SFH comprise indicate " the S-SFH change count " of the version of the S-SFH of current transmission, indicate in corresponding superframe, whether send S-SFH " S-SFH schedule information bitmap ", be designated as S-SFH transmission distribute LRU number " S-SFH size ", instruction S-SFH transformat " S-SFH repeat number ", indicate which kind of S-SFH SP reformed " S-SFH SP changes bitmap " etc.The size of " S-SFH schedule information bitmap " and " S-SFH SP changes bitmap " field equals the sum of the SP of S-SFH.
S-SFH sends actual system information, and as mentioned above, the system information of sending can be included in 3 attached bags according to its characteristic, and each attached bag is called as S-SPH SPn(n=1, and 2,3).Each S-SFH SP information element (IE) has different transmission cycles.When the transmission cycle of SP1 is T sP1, SP2 transmission cycle be T sP2and the transmission cycle of SP3 is T sP3time, the transmission cycle of attached bag such as can pass through T sP1<T sP2<T sP3represent.
For the continuous communiction with base station, terminal should upgrade the system information sent via S-SFH.But, when system information is constant, if S-SFH decoded and upgrade, may be poor efficiency in the power consumption of terminal.Terminal in this specification can carry out decoding and the renewal of S-SFH when the system information change sent via S-SFH.
And terminal should detect from the information errors the P-SFH of base station reception before the renewal of the system information of base-station transmission in execution.
Fig. 4 is the flow chart that order shows the process of the information errors in the P-SFH that receives from base station according to an illustrative embodiments sense terminals.
P-SFH can comprise " 4 LSB Hyper Frame Number ", " S-SFH change count (hereinafter referred to as " CC ") ", " S-SFH schedule information bitmap ", " S-SFH size ", " S-SFH repeat number ", " S-SFH SP change bitmap (hereinafter referred to as " CB ") " and the Cyclic Redundancy Check for error detection.
Usually, in order to check via air interface send P-SFH in information in whether there is mistake, terminal based on receive data calculate crc value.Then terminal judges whether there is mistake in the information in P-SFH according to the crc value calculated.
This description presents under both making to judge not have vicious situation in by the general P-SFH error checking procedure of CRC also additionally uses 4 LSB SFN fields in P-SFH to judge whether the process made a mistake.
First, the P-SFH(S401 of decoding terminals reception).
Terminal judges whether occur mistake (S403) in the information in P-SFH mainly through the decoding crc value be included in P-SFH.
If terminal produces judged result according to the mistake by crc check judge to there is mistake in respective superframe, then superframe is treated to mistake (S417).If judge not occur any mistake, then terminal successfully receives critical system information by Initial network registration (entrance) process (DL is synchronous) and calculates Hyper Frame Number (SFN).
Therefore, the Hyper Frame Number (SFN) in the P-SFH that sent base station of terminal compares to judge whether corresponding P-SFH is correctly sent (S405) error-free to the SFN that itself calculates.
If there occurs mistake in the information of terminal judges in P-SFH, then corresponding superframe can be treated to and has mistake and therefore do not take any further action (S417) by terminal.
If judge from the SFN in the P-SFH of base station transmission identical with the SFN that terminal calculates, then terminal judges respective superframe does not have mistake (S407).
When sending S-SFH in respective superframe, terminal can calculate CRC for S-SFH.If judge do not have mistake in the information in S-SFH, then corresponding terminal takes normal action to corresponding superframe.
After this, the visual angle from terminal is provided the method that the system information change message sent via P-SFH upgrades critical system information.
Fig. 5 shows the method for the time point of informing the system information of application change via P-SFH.
Change bitmap (CB) about the S-SFH change count (CC) sent via P-SFH and S-SFH SP, as shown in Figure 5, CC can be changed in units of S-SFH SP by base station.
In Figure 5, CC indicates change count, and whether the critical system information that the instruction of this change count sends via S-SFH changes, and SI indicates the schedule information bitmap of S-SFH, and expression is sent to the S-SFH SP of terminal after being scheduled in respective superframe.And CB instruction about the change bitmap of S-SFH, and represents the SP of the vicissitudinous system information of tool in respective superframe.
With reference to Fig. 5, if suppose that CC, SI and CB information of S-SFH sends via the P-SFH in superframe, and be scheduled in the first superframe and the S-SFH SP1 of transmitting system Information invariability and S-SFH SP2, current hypothesis is in the P-SFH of the first superframe, CC equals 25, SI bitmap, and to be set to " 110 " to indicate S-SFH SP be SP1 and SP2, and the same with CB above, CB is maintained " 000 ", does not have vicissitudinous S-SFH SP because current.
In Figure 5, because the system information belonging to S-SFH SP IE changes, in the superframe of S-SFH SP IE first sending respective change, S-SFH change count increases (increasing progressively).That is, first send change SP1 and SP2 time point the second superframe in produce from 25 to 27 CC counting increase.Herein, in units of SP, counter increase is carried out.Therefore, two SP changes, so increase by two countings.Therefore, CC becomes 27.
Therefore, in the second superframe, when CC is current be increased to 27, these system informations can send via P-SFH, SI bitmap is set to " 110 " to indicate the S-SFH SP dispatched in the second superframe to be SP1 and SP2, and CB is set to " 110 ", that is, the position information saltus step of first and second positions of CB changes to indicate SP1 and SP2.But according to the modification of this specification, CB can by being set to 1 by the place value corresponding to S-SFH SP and other place value being set to the SP of 0 and instruction change.In this case, can after place value be set to " 110 ", that is, make the position information saltus step of the first and second positions be 1 to indicate after SP1 and SP2 change, send CB.
And, do not change in system information and only dispatch SP1 in the 3rd superframe.Therefore, in the P-SFH during the 3rd superframe, CC is maintained 27, SI bitmap and is set to " 100 " to indicate the S-SFH SP of scheduling to be SP1, and CB is maintained " 110 ".
Meanwhile, base station not only must inform that the system information of terminal current application has changed but also must inform the decision of the terminal when system information of application change.Such as, by being used to indicate the change information application Indication message of a common application time point or application version, or by using independent instruction to be used for multiple change information application Indication messages of the Applicative time point of the S-SFH SP IE of multiple change, the time point of the system information of terminal applies current application can be informed in base station by some methods.
When the change information application Indication message by instruction common application time point or application version informs the Applicative time point of the system information for changing, base station can by informing the Hyper Frame Number of instruction application-specific time point or deviant or it must perform the time point of renewal by using application change counting (ACC) information notification terminal of instruction application version.
And change information application Indication message can be sent to terminal via P-SFH, S-SFH or MAP message.
The ACC that illustrative embodiments shown in Fig. 5 shows the application version of the system information of instruction change is sent to terminal via P-SFH, makes it possible to the system information putting application change at common time.
After S-SFH SP1 and SP2 that have sent change via the second superframe, base station can by ACC from 25 become after 27 send ACC with S-SFH SP1 and SP2 from the 3rd superframe application change.
After S-SFH SP1 and SP2 receiving change, terminal can identify the system information from the 3rd superframe application change, identical with CC in the 3rd superframe, after ACC changes to 27, send ACC, and the application of then executive system information.
Herein, can at identical time point for these S-SFH SP application system information change operation with identical version.
Fig. 6 illustrates another illustrative embodiments sending change information application Indication message via P-SFH, and the instruction of this change information application Indication message is by the system information in single common application time point application change.
The illustrative embodiments of Fig. 6 is identical with the illustrative embodiments of Fig. 5, only increases in units of the SP of CC counting in units of superframe but not shown in Fig. 5.That is, first send change SP1 and SP2 time point the second superframe in CC be increased to 26 from 25.
Therefore, be similar to CC, the ACC of the application version of the system information of instruction change with superframe instead of SP for unit increases.After S-SFH SP1 and SP2 that have sent change via the second superframe, in order to S-SFH SP1 and SP2 from the 3rd superframe application change, ACC can be changed to 26 for transmission from 25 by base station.
After S-SFH SP1 and SP2 that have received change, terminal can identify the system information from the 3rd superframe application change, and in the 3rd superframe, identical with CC, ACC is sent out after changing to 27, and the application of then executive system information.
Fig. 7 shows by being included in the illustrative embodiments sending change information application Indication message in MAP (MAP), and the instruction of this change information application Indication message is by the system information in single common application time point application change.
After S-SFH SP1 and SP2 sending change via the second superframe, in order to S-SFH SP1 and SP2 from the 3rd superframe application change, identical with CC, ACC can be changed to 26 from 25 by base station, and sends it via MAP.
Herein, preferably, the SP for sending corresponding MAP can be pre-determined.That is, such as, can be determined in advance as send MAP in the first subframe or each subframe.
Receive S-SFH SP1 and SP2 changed during the second superframe after, terminal recognition applies the system information relevant to S-SFH SP1 and SP2 changed by from the 3rd superframe, identical with CC in the 3rd superframe, the ACC of 26 is sent out and the application of executive system information.
The illustrative embodiments of Fig. 7 illustrates that CC counting and ACC counting are that unit increases with superframe typically.But be similar to the illustrative embodiments of Fig. 5, the illustrative embodiments of Fig. 7 may be embodied as and makes CC counting and ACC counting increase in units of SP.After this, in order to task of explanation, illustrate that CC changes in units of SP or superframe, but should be appreciated that these two kinds of methods all can be applicable to the disclosure.
Fig. 8 shows the illustrative embodiments sending change information application Indication message, and this change information application Indication message indicates respectively in the system information of independent utility time point application change.
Send S-SFH SP1 and SP2 changed via the second superframe after, in order to S-SFH SP1 and SP2 from the 3rd superframe application change, changing to after 26 by ACC1 from 25, base station sends ACC1 to terminal.
Receive S-SFH SP1 and SP2 changed during the second superframe after, terminal recognition goes out applies the system information relevant to the S-SFH SP1 of change by from the 3rd superframe, identical with CC in the 3rd superframe, ACC1 is sent out after being increased to 26, and the application of then executive system information.
On the other hand, because ACC2 still has the value of 25 in the 3rd superframe, terminal can know still not application change S-SFH SP2 and thus do not perform for change SP2 system information upgrade.After this, when reception becomes the ACC2 of 26, the system information that terminal can perform for SP2 upgrades.
Fig. 9 shows another illustrative embodiments sending change information application Indication message, and this change information application Indication message indicates respectively in the system information of independent utility time point application change.
Different from the illustrative embodiments of Fig. 8 that CC increases in units of superframe, the illustrative embodiments of Fig. 9 shows CC to be increased in units of SP.Therefore, ACC counting also can increase in units of SP.
Base station sends S-SFH SP1 and SP2 of change via the second superframe, and also sends increase by 2 in response to the change of SP1 and SP2 thus be increased to the CC of 27.
And in order to the S-SFH SP1 from the 3rd superframe application change, ACC1 is changed to 27 from 25 by base station, thus sends to terminal.
Receive S-SFH SP1 and SP2 during the second superframe after, terminal recognition goes out applies the system information relevant to the S-SFH SP1 of change by from the 3rd superframe, identical with CC in the 3rd superframe, ACC1 is sent out after being increased to 27, and the application of then executive system information.
On the other hand, because ACC2 still has the value of 25 in the 3rd superframe, terminal can know still not application change S-SFH SP2 and thus do not perform for change SP2 system information upgrade.After this, when receiving the ACC2 being changed to 27, the system information that terminal can perform for SP2 upgrades.
Figure 10 shows the illustrative embodiments of the application version sending the system information of change via each S-SFH SP.
As shown in Figure 10, the ACC of the application version of the SP of instruction change can send by being included in each S-SFH SP instead of P-SFH.
Base station comprises ACC by each in S-SFH SP1 and SP2 of change and sends ACC via the second superframe.
After S-SFH SP1 and SP2 receiving change, terminal recognition goes out does not apply the system information relevant to the S-SFH SP1 changed in the second superframe, because be 25 via the ACC of S-SFH SP1 transmission.
But because the ACC sent via S-SFH SP2 is 27, terminal recognition to go out in the second superframe the application system information relevant with the S-SFH SP2 changed, and the application of then executive system information.
After this, because the ACC sent via S-SFH SP1 is increased to 27 in the 3rd superframe, terminal recognition applies the system information relevant to S-SFH SP1 in the 3rd superframe, and the application of then executive system information.
Figure 11 shows the illustrative embodiments of the application skew sending the system information of change via each S-SFH SP.
As shown in figure 11, change information application Indication message can be instructed to the skew replacement of the time point of the S-SFH SP IE of application change.
Base station sends S-SFH SP1 and SP2 of change via the second superframe.
Herein, each S-SFH SP comprises the offset information (that is, applying Super frame Offset (ASO)) of the system information of instruction application change.
After S-SFH SP1 and SP2 receiving change, because the ASO be included in each in S-SFH SP1 and SP2 is 1, terminal recognition goes out from the system information relevant with S-SFH SP1 and SP2 changed of the 3rd superframe application as frame subsequently.
Herein, when ASO uses 1 to configure, if ASO value is " 0b0 ", it can indicate the system information of application change in the superframe of current reception, and if be " 0b1 ", it can indicate the system information of application change in superframe subsequently.
Table 1 below illustrates the S-SFH ASO of 2 configured according to another illustrative embodiments.
sFH ASO describe
00 apply corresponding S-SFH SP in the current superframe.
01 corresponding S-SFH SP. is applied from superframe (frame number+1) subsequently
10 corresponding S-SFH SP is applied from frame number+2.
11 corresponding S-SFH SP is applied from frame number+3.
As shown in table 1, the ASO value in the specific S-SFP SP sent during the 3rd superframe is 0b10, can apply corresponding S-SFH SP from the 5th superframe (3+2).
Herein, because ASO is sent to terminal via P-SFH, ASO can indicate when common time point (when only comprising an ASO) application change system information or apply each S-SFH SP(when comprising ASO as many with the sum of S-SFH SP at independent time point).
Figure 12 shows the illustrative embodiments sending the application message relevant to the system information of change with bitmap form.
As shown in figure 12, base station can send change information application Indication message with bitmap form via P-SFH, thus inform for the S-SFH SP of current application a common application time point or application version or inform whether apply each S-SFH SP.
The application Indication message of bitmap form can send via MAP or each S-SFH SP, and each S-SFH SP can apply in different time points, and it is also the same for both having made these S-SFH SP have identical version.
After send S-SFH SP1 and SP2 changed via the second superframe, in order to the S-SFH SP1 from the 3rd superframe application change, ACC is being changed to transmission ACC after 27 from 25 and sending application change bitmap (ACB) after being set to 1 by first of the application change bitmap (ACB) corresponding to S-SFHSP1 by base station.
Therefore, because S-SFH SP3 is constant, former state application information above.
Receive S-SFH SP1 and SP2 of change during the second superframe after, terminal recognition goes out applies the system information relevant to the S-SFH SP1 of change by from the 3rd superframe, identical with CC in the 3rd superframe, ACC is 27, and the place value of ACB corresponding to S-SFH SP1 is set to 1, and the application of then executive system information.
On the other hand, because the place value corresponding to the ACB of S-SFH SP2 is set to 1, terminal can identify still does not apply the system information relevant to S-SFH SP2.Herein, ACC can be preferably constant, until apply the system information relevant to the S-SFH SP2 changed.That is, base station can not change ACC, until apply all S-SFH SP with identical version.
Figure 13 shows a kind of method, and wherein the system information or its Applicative time point of informing whether application change are repeated to transmit by each S-SFH SP in base station.
Base station can repeat to send identical S-SFH SP to strengthen the possibility being positioned at the terminal receiving system information of cell edge when considering MPS process in a continuous manner.
In fig. 13, S-SFH SP1 is transmitted repeatedly 3 times (301,302 and 303), and S-SFH SP2 is transmitted repeatedly 2 times (311,312).
The terminal adjacent with base station more may normally be decoded the S-SFH SP1(301 sent in the first superframe) and SP2(302).But, away from base station terminal more may only after being received in S-SFH SP1302 and SP2312 sent in the second superframe just normal decoder change system information.
Herein, base station can present information with the as many bitmap form of sum of sum or S-SFH SP1 with the S-SFH SP sent in respective superframe, and the system information that the instruction of this information sends is the system signal sent at first or the system information finally repeating transmission.
Such as, if send S-SFH SP1 and SP2 in particular superframe, then can distribute to S-SFH SP1 and second can distribute to S-SFH SP2 for first.
Figure 14 shows a kind of method, wherein base station by each S-SFH SP of instruction repeat to transmit bitmap and SP repeat to transmit the system information or its Applicative time point of informing whether application change.
In fig. 14, base station sends the S-SFH SP1(401 changed via the second superframe) and SP2(402).Suppose that S-SFH SP1 repeatedly sends 2 times (401,402) with the 3rd superframe frame via the second surpassing, and S-SFH SP2 sends once (412) via the second superframe.
Therefore, because first S-SFH SP1 is sent, thus in the second superframe, finally repeat to indicate (LRI) first to be set to " 0 ", and because S-SFH SP2 is first time is also finally repeat to send, its second is set to " 1 ".
Because the S-SFH SP1 of change is finally repeated to send (402) in the 3rd superframe, base station is by being set to " 1 " by its first and sending LRI.
After S-SFH SP1 and SP2 of the counting and change that receive the change added via the second superframe, terminal recognition go out the position from LRI is set to 1 superframe or subsequently superframe apply corresponding S-SFH SP.That is, from the 3rd or the 4th superframe application S-SFH SP1, and from second or the 3rd superframe application S-SFH SP2.
According to a kind of modification, for be different from LRI repeat at first indicate (FRI), if change count is different and FRI is set to 1, terminal can judge the S-SFH SP applying previous versions.Herein, at first and finally repeat transmission, terminal must be set to finally to repeat transmission.
Figure 15 shows a kind of method, and wherein base station impliedly judges the time point of the system information of application change based on the Scheduling Bit Map of S-SFH SP.
Hint type method instruction base station shown in the illustrative embodiments of Figure 15 does not send the information relevant to the system information of current application separately, and terminal impliedly identifies whether system information and the Applicative time point thereof of application change by S-SFH SP Scheduling Bit Map.
Be similar to the execution mode described in Figure 13 and Figure 14, base station repeatedly can send identical S-SFH SP in a continuous manner for MPS process.
Terminal can identify that corresponding to the S-SFH SP that S-SFH SP schedule information (SI) is changed to the position of " 0 " from " 1 " in continuous superframe is the S-SFH SP finally repeating to send last superframe.
Base station can send via the second superframe S-SFH SP1 and SP2 changed.S-SFH SP2 via the second superframe send once (1511) and S-SFH SP1 via second and the 3rd superframe repeatedly send 2 times (1501,1502).
After S-SFH SP1 and SP2 receiving change, the place value that then terminal can identify corresponding to the SI of S-SFH SP2 is set to " 1 " and is changed to " 0 " in the 3rd superframe in the second superframe, and be also identified in the S-SFH SP2 sent in the second superframe be finally repeat send S-SFH SP.
Therefore, can from second or the 3rd S-SFH SP2 of superframe application change.
