Starting radio frames meet condition: (SFN) mod T=floor (x/10), wherein T is dispatching cycle.Dispatch the starting subframe a of window
Meet condition: a=x mod 10.Thus, it is determined that starting radio frames, starting subframe, length and the scheduling week of scheduling window
Phase, base station can send inessential system information in the scheduling window using T as the period.
Wherein, base station does not need to send inessential system information in the continuous subframes in scheduling window.For being in subframe
No there are inessential system informations, can pass through Physical Downlink Control Channel (Physical Downlink Control
Channel, PDCCH) it indicates.
But in NR, inessential system information is scheduling on demand, if using in LTE system to inessential system
The scheduling mechanism of information, UE can not know when the transmission of the inessential system information terminates, it will cause UE periodical
Unlimitedly receive inessential system information；If going to receive the inessential system information always, time delay is not only increased,
The increase of UE computation complexity is also resulted in, while increasing UE power consumption；Meanwhile it there is also UE and can not receive required inessential system
The case where information.Therefore, new wireless technology is not suitable for the scheduling mechanism of inessential system information in the prior art.
The embodiment of the present invention will send inessential system information based on the scheduling request decision of user, and determine inessential system
The scheduling information for information of uniting, meanwhile, indicate that the end of inessential system information sends opportunity, namely remaining scheduling in scheduling information
Number and/or last scheduling occasion can allow user terminal to know that inessential system information terminates to send at what time；If
Period user terminal there is no corresponding inessential system information, can initiate in time to base station for required inessential system letter
The scheduling request of breath guarantees that user terminal receives the reliability of inessential system information, while reducing user terminal power consumption.
To make the above purposes, features and advantages of the invention more obvious and understandable, with reference to the accompanying drawing to the present invention
Specific embodiment be described in detail.
Fig. 2 is a kind of flow chart of the dispatching method of inessential system information of the embodiment of the present invention.
The dispatching method of inessential system information shown in Fig. 2 may comprise steps of:
Step S201: user terminal is received to the scheduling request of inessential system information；
Step S202: being the user terminal configuration pin to the inessential system information in necessary system information
Scheduling information；
Step S203: the necessary system information is sent to the user terminal, so that the user terminal is according to institute
Scheduling information is stated to receive the inessential system information.
It will be apparent to a skilled person that necessary system information can be MIB, SIB1 and SIB2, inessential system
System information can be SIB3~SIB19 etc., and the embodiment of the present invention is without limitation.
In specific implementation, when UE needs inessential system information, it can send to base station for inessential system information
Scheduling request.In step s 201, base station receives UE to the scheduling request of inessential system information, then determines to send described non-
Necessary system information.It is the user terminal configuration pin to the inessential system in necessary system information in step S202
The scheduling information for information of uniting.In final step S203, the necessary system information is sent to UE, so that UE is according to the scheduling
Information receives the inessential system information.
Wherein, the scheduling information may include remaining scheduling times (Remaining transmission number)
And/or last scheduling occasion, necessity system information are sent by way of periodic broadcast, necessity system letter
The dispatching cycle of breath was the first dispatching cycle.Remaining scheduling times are used to indicate the remaining scheduling times of inessential system information,
Last scheduling occasion is used to indicate the opportunity or time of inessential system information last time scheduling.
It will be apparent to a skilled person that the scheduling information can also include dispatching sequence, the length for dispatching window
The dispatching cycle of degree and inessential system information, in order to which UE can determine that starting to receive inessential system believes according to scheduling information
The opportunity of breath.
The scheduling information of SI is configured compared in LTE system, increases inessential system information in the present invention.Namely
It says, indicates that the end of inessential system information sends opportunity in scheduling information, namely when remaining scheduling times and/or last scheduling
Machine can allow user terminal to know that inessential system information terminates to send at what time；If period user terminal does not obtain
Accordingly inessential system information is obtained, the scheduling request for being directed to required inessential system information can be initiated to base station in time, guaranteed
User terminal receives the reliability of inessential system information, while reducing user terminal power consumption.
In specific implementation, necessity system information is sent repeatedly within first dispatching cycle, and content one every time
It causes.Specifically, necessary system information can be sent 2 times, 3 times or 4 times within the first dispatching cycle, the no more than first scheduling
The quantity for the radio frames that period occupies.
In specific implementation, step S203 be may comprise steps of: in described where the inessential system information
In one dispatching cycle, when sending the necessary system information for the first time, the remaining scheduling times in the scheduling information are subtracted
One.Since necessary system information repeated to send repeatedly within same first dispatching cycle, and content is consistent every time, and in order to guarantee
The remaining scheduling times that the necessary system information sent every time carries are identical and correct, therefore are sending the necessary system for the first time
When information of uniting, the remaining scheduling times in the scheduling information are subtracted one.
In specific implementation, step S203 can be with the following steps are included: when the residue scheduling times are decremented to m-1, m be
The user terminal receives the minimum number of the inessential system information, sends institute for the first time within first dispatching cycle
When stating necessary system information, cancels in the necessary system information and carry the scheduling information.That is, since base station is sent out
When sending inessential system information, multiple UE can be existed simultaneously and received, in order to guarantee multiple UE to inessential system information
Received reliability, base station need to guarantee the inessential system that every UE is determined according to scheduling information when sending scheduling information
The practical receive number of information is at least m times.
Alternatively, m is the minimum number that the user terminal receives the inessential system information, refer to that UE can be attempted
Received minimum number.That is, if UE once to receive inessential System Information reception not right, UE can also attempt to receive
Next time, m is that UE attempts to receive the minimum number of the nonessential system message.
Technical solution of the present invention is illustrated with a non-limiting embodiment below.
Referring to figure 3., Fig. 3 is a kind of scheduling time diagram of inessential system information of the embodiment of the present invention.UE needs
When inessential system information SIB18, the scheduling request for being directed to SIB18 can be sent to base station, such as send and dispatch in radio frames 4
Request.Base station receives UE to the scheduling request of inessential system information, then determines to send SIB18.In necessary system information
It is scheduling information of the UE configuration pin to SIB18 in SIB1.
In conjunction with Fig. 1, the first dispatching cycle was 80ms namely 8 radio frames.Base station is sent 4 times within the first dispatching cycle
SIB1, and content is consistent namely identical for the scheduling information of SIB18 every time.Specifically, base station is in 0 first time of radio frames
SIB1 is sent, sends remaining SIB1 three times in radio frames 2,4,6, and identical as the SIB1 content sent in radio frames 0；With such
It pushes away, sends SIB1 for the first time in radio frames 8, send remaining SIB1 three times in radio frames 10,12,14, and send in radio frames 8
SIB1 content it is identical.Wherein, SIB1 is sent in the subframe of radio frames 5.Similarly, radio frames 16,24 ... in 8n, can refer to
Above-mentioned statement, wherein n is positive integer.
Specifically, in conjunction with Fig. 1 and Fig. 3, base station sends SIB1 in the first dispatching cycle radio frames 8 to radio frames 15
When, the remaining scheduling times N of SIB1 carrying is 3.The scheduling information can also include: that the length of the scheduling window of SIB18 is
5ms namely 5 subframe；T2 dispatching cycle of SIB18 is 160ms namely 16 radio frames；The dispatching sequence n of SIB18 is 3.
UE after radio frames 8 to the inscribed SIB1 for receiving base station transmission of radio frames 15, is parsed after radio frames 4 send scheduling request
The scheduling information of SIB1 carrying.The UE can be calculated according to scheduling information obtain SIB18 scheduling window starting radio frames and
Subframe is originated, detailed process is as follows:
X, x=(n-1) w=(3-1) 5=10 are calculated first；The starting radio frames of scheduling window meet condition: (SFN) %16
=floor (x/10)=floor (10/10)=1, then, it is 1 according to the starting radio frames that possible scheduling window is calculated,
17,33,49 ...；The starting subframe of scheduling window meets condition: a=x mod 10=10mod 10=0.Window is dispatched in radio frames 1,
Start in 17,33,49,65 ... subframe 0.
Since base station just starts to carry scheduling information in the SIB1 that radio frames 8 are sent, it is possible thereby to determine rising for scheduling window
Beginning radio frames are 17,33,49 ....Meanwhile it is 3 times that remaining scheduling times are configured in scheduling information, it is possible to determine radio frames
17,33, the 49 starting radio frames as scheduling window.That is, the UE is when receiving inessential system information, only in radio frames
It goes to receive in 17,33,49, radio frames in radio frames 65 and later then no longer go to receive.
It is understood that base station, when configuring remaining scheduling times for the first time for UE, which is remaining adjust
Spend the maximum value of number.
Referring to figure 3., for the UE in radio frames 8 to the inscribed SIB1 for receiving base station transmission of radio frames 15, due to scheduling
The length of window W is 5, thus the subframe 0 of scheduling window W occupancy radio frames 17,33,49 to subframe 5.Since base station is not notified that UE exists
Which subframe of scheduling window W has sent SIB18.The UE can each subframe that scheduling window W is occupied (namely subframe 0,1,2,3,
4,5) decoding is attempted in, until being successfully received SIB18.
Specifically, if it is that 3, UE is receiving necessity system that base station, which still configures residue scheduling times N in radio frames 16,
When information of uniting, go to receive inessential system information in radio frames 17,33,49 according to the determination of remaining scheduling times 3.Meanwhile by
Identical necessary system information is sent in radio frames 18/20/22 and radio frames 16 in base station, that is, necessary system information carries
Configuration residue scheduling times N be 3.UE is dispatched when receiving the necessary system information of radio frames 18/20/22 according to residue
The determination of number 3 goes to receive inessential system information in radio frames 33,49,65.
But base station will not send inessential system information, repetition of the SIB1 within the first dispatching cycle in radio frames 65
It sends so that the judgement on UE finishing scheduling opportunity is inconsistent.The UE of necessary system information is received in radio frames 18/20/22,
It is originated in the subframe 0 of radio frames 65 as scheduling window, the blind examination PDCCH in each subframe in scheduling window just can know that correspondence
Whether there is SIB18 in subframe, if obtaining the scheduling request for retransmitting less than ability to base station and being directed to SIB18, increases UE's
Power consumption.In order to avoid there is the problem, the UE of necessary system information is received in radio frames 18/20/22, it can be determined that current son
Whether SIB18 is sent between frame and radio frames 16, if it is then the UE is needed scheduling times remaining in scheduling information
Subtract 1 as effective remaining scheduled transmission number (namely real surplus scheduling times).But it does so and increases answering for UE
Miscellaneous degree.
Therefore, in the present embodiment, within first dispatching cycle where the inessential system information, for the first time
When sending the necessary system information, the remaining scheduling times in the scheduling information are subtracted one.
Specifically, referring to figure 3., inessential system information SIB18 is sent for the first time in radio frames 17, at radio frames 17
In in the radio frames 16 to radio frames 17 of the first dispatching cycle, then base station when radio frames 16 send SIB1 for the first time, updates
Remaining scheduling times N is also decremented to 2 by 3 by the scheduling information of SIB18.So, it is sent out in radio frames 16,18,20,22 ... 30
In the SIB1 sent, the remaining scheduling times N of carrying is 2.So, the UE of SIB1 is received in radio frames 16, it will wireless
Frame 17 and radio frames 33 carry out the reception of SIB18；The UE of SIB1 is received in radio frames 18,20,22 ... 30, it will in radio frames
The reception of 33 and the progress of radio frames 49 SIB18.
The rest may be inferred, and inessential system information SIB18 is sent at second of radio frames 33, and radio frames 33 are in the first scheduling
In the radio frames 32 to radio frames 39 in period, then base station updates the scheduling of SIB18 when radio frames 32 send SIB1 for the first time
Remaining scheduling times N is also decremented to 1 by 2 by information.So, in the SIB1 that radio frames 32,34,36,38 ... 46 are sent,
The remaining scheduling times N of carrying is 1.So, the UE of SIB1 is received in radio frames 32, it will carry out in radio frames 33
The reception of SIB18；The UE of SIB1 is received in radio frames 34,36,38 ... 46, it will carries out the reception of SIB18 in radio frames 49.
Preferably, when sending inessential system information due to base station, multiple UE can be existed simultaneously and received, in order to protect
Multiple UE are demonstrate,proved to the reliability of inessential System Information reception, base station when sending scheduling information, need to guarantee every UE according to
The practical receive number for the inessential system information that scheduling information determines is at least m times.The value of M is greater than 1 and is less than or equal to residue
The maximum value of scheduling times.When the residue scheduling times are decremented to m-1, m is that the user terminal receives the inessential system
The minimum number for information of uniting, when sending the necessary system information for the first time within first dispatching cycle, in described necessity
Cancel in system information and carries the scheduling information.
Specifically, referring to figure 3., in order to guarantee every UE according to the practical reception time of the determining SIB18 of scheduling information
Number is at least 2 times.So when remaining scheduling times are decremented to 1, when sending SIB1 for the first time within first dispatching cycle,
Cancel in SIB1 and carries the scheduling information.That is, base station is cancelled in SIB1 and being taken when radio frames 32 send SIB1
With the scheduling information.So, it for all UE for having received SIB1, that is, receives in radio frames 8 to radio frames 30
The UE of SIB1, confirmable residue scheduling times are respectively 3 times and 2 times, it is ensured that practical reception of every UE to SIB18
Number is at least 2 times, ensure that multiple UE to the reliability of inessential System Information reception.
Cancel after carrying the scheduling information in the SIB1 that base station radio frame 32 is sent, it will in the SIB1 that subsequent UE is received
It no longer include the scheduling information of SIB18.So UE can send scheduling request to base station, to notify base when needing SIB18
The UE that stands needs SIB18.
It is understood that the practical receive number of user terminal can carry out adaptability according to actual application environment
Configuration, the embodiment of the present invention are without limitation.
It should be noted that the embodiment of the present invention is SIB1 with necessary system information, inessential system information is that SIB18 is
Example is illustrated, and does not constitute the limitation to the embodiment of the present invention.In actual application, inessential system information is also possible to more
A system information block, the multiple system information block have identical dispatching cycle.
In another embodiment of the present invention, the last scheduling occasion includes that last time sends the inessential system information
Starting radio frames.Technical solution of the present invention is illustrated with a non-limiting embodiment below.
UE need inessential system information SIB18 when, can to base station send be directed to SIB18 scheduling request, such as
Radio frames 4 send scheduling request.Base station receives UE to the scheduling request of inessential system information, then determines to send SIB18.?
It is scheduling information of the UE configuration pin to SIB18 in necessary system information SIB1.
