Description
Technical field
The present invention is generally related to wireless communication field, more specifically, is related to one kind and is adaptively adjusted resource point
The method and apparatus of pre-scheduling resource allocation with the period.
Background technique
Third generation partner program (3GPP) has had been approved by research project " the Study on for Rel-13
Latency reduction techniques for LTE".The purpose of the research project is research and improves based on Rel-13
Packet data time delay.There are many existing applications and future will benefit from time delay reduction for the new opplication of appearance, or even want
Time delay is asked to reduce, such as Web application, real-time application and mission-critical communication (Mission-critical
Communication it) applies.Packet data time delay is extremely important not only for the intended response of system, and is a shadow
Ring the parameter of handling capacity.In 3GPP long term evolution (LTE) system, there is the total of user equipment (UE) of the Multiple factors for connection
End-to-end delay work.A kind of current method for reducing time delay is by using pre-scheduling or to be semi-persistently scheduled (semi-
Persistent scheduling, SPS) strategy come reduce obtain scheduling grant time.
Currently, there are two types of the dispatching methods of type, and one is the scheduling based on scheduling grant, another kind is for VoIP
It is semi-persistently scheduled.
Fig. 1 shows the schematic diagram of the signaling of the scheduling process in up-link based on scheduling grant in the prior art.
Fig. 2 shows in the prior art in downlink system the signaling of the scheduling process of (DL) based on scheduling grant schematic diagram.
As shown in fig. 1, the UE for having data to send must send to base station (such as eNB) before sending data grouping and adjust
Degree requests (Scheduling Request, SR) and receives scheduling grant from the base station.However, in order to send SR, UE is necessary
Wait the effective Physical Uplink Control Channel of SR (PUCCH) resource, that is, it can send the PUCCH of SR, and the effective PUCCH of SR
The period of resource is 1-80ms.After UE has sent SR by the PUCCH, base station receives and decodes SR, and is the UE tune
Spend allocation schedule license.Then the scheduling grant is sent to UE by base station.When UE receive and decode dispatch the license when, can be with
Start the transmission of UL data by Physical Uplink Shared Channel (PUSCH).
DL shown in Fig. 2 is transmitted, since data to be sent are located at base station side, base station sends it in data
Before do not need as UL transmit like that execute the process of scheduling request, but base station still needs and is sent to data and dispatch command
UE, and be decoded by UE, and this is there is still a need for the regular hour is consumed, to increase time delay.
For being semi-persistently scheduled for VoIP, since VoIP business is periodically, base station can be distributed to UE
The resource of fixed cycle, the fixed cycle are used for VoIP business.
Business dominant for downlink, if FTP is downloaded, uplink time delay performance is extremely important, because for example
TCP ACK message will be sent by uplink.For the application with discrete short packet data, when scheduling grant obtains
Prolong and also accounts for big part in total delay therefore be also required to reduce delay.
Summary of the invention
From the above it can be seen that based on the scheduling scheme of scheduling grant for the business with urgent delay requirement not
It is enough effective.In addition, the persistent scheduling with the fixed cycle is also not efficient enough for acyclic business.
Therefore difficulty is the period how is arranged, if a larger value will be set as in the period, it cannot be guaranteed that time delay,
And if a smaller value will be set as in the period, periodic resources cannot be efficiently used, this will lead to the wasting of resources.
In view of the above problems, the invention proposes a kind of adaptive pre-scheduling scheme with the variable cycle.
According to the first aspect of the invention, it provides one kind and is adaptively adjusted resource allocation cycle at base station or UE
Pre-scheduling resource allocation method, comprising: whether determine has data receiver or data to send in the resource allocation cycle；
If it is determined that sending in the resource allocation cycle without data receiver and data, then the resource allocation cycle is at least based on
Adjustment rule adjust the resource allocation cycle；And whether there are data to connect in determining resource allocation cycle after the adjustment
It receives or data is sent.
According to another aspect of the present invention, it provides one kind and is adaptively adjusted resource allocation cycle in base station or UE
Pre-scheduling resource allocation device, comprising: judging unit, for determining whether there are data to connect in the resource allocation cycle
It receives or data is sent；And adjustment unit, for if it is determined that without data receiver and data in the resource allocation cycle
It sends, then at least adjusts the resource allocation cycle, and the judgement based on the adjustment rule of the resource allocation cycle
Whether unit is also used to determine has data receiver or data to send in resource allocation cycle after the adjustment.
Using the program, time delay can not only be reduced by pre-allocation of resources, and can be received based on UL (for uplink
For link) and DL send (for downlink) and adjust the period of pre-scheduling, and can be suitable for having urgent
The aperiodicity characteristic of the business of delay requirement.

Specific embodiment
The preferred embodiment that the present invention will be described in more detail below with reference to accompanying drawings.Although showing the present invention in attached drawing
Preferred embodiment, however, it is to be appreciated that may be realized in various forms the present invention without the embodiment party that should be illustrated here
Formula is limited.On the contrary, thesing embodiments are provided so that the present invention is more thorough and complete, and can will be of the invention
Range is fully disclosed to those skilled in the art.
Pre-scheduling resource that Fig. 3 shows embodiment according to the present invention, being adaptively adjusted resource allocation cycle point
The flow chart for the method 300 matched.
From figure 3, it can be seen that in addition to base station eNB and UE are required about resource allocation cycle adjustment institute in step 310 execution
Signalling exchange except, during the adaptive adjustment of resource allocation cycle, base station does not need to configure to UE new or other
Resource allocation cycle, but the two independently adaptively adjusts the resource allocation cycle according to ad hoc rules respectively.
Firstly, base station eNB sends the adjustment of the initial value, resource allocation cycle of resource allocation cycle to UE in step 310
Regular and possible adjusting parameter.
Preferably, base station can be sent to UE about resource allocation cycle by wireless heterogeneous networks (RRC) signaling
Above- mentioned information.
Next, whether base station determination receives UL data in the resource allocation cycle in step 320.
If base station is not received by UL data in the resource allocation cycle, in step 330, base station is at least based on providing
The adjustment rule of source assignment period carrys out adjustresources assignment period.
More specifically, then base station, which reduces, is somebody's turn to do if the base station determine that being not received by UL data in the resource allocation cycle
The size of resource allocation cycle.In this way, for the transmission of aperiodicity data, in subsequent reduced resource point
With bigger a possibility that receiving data transmission in the period.
In a kind of implementation of the invention, adjustment rule includes the rule of exponentials.In this case, adjusting parameter packet
Include the truth of a matter value of the rule of exponentials, and adjustresources assignment period further include: adjust based on the rule of exponentials and the truth of a matter value
Resource allocation cycle.However, the adjustment is regular and/or should it will be understood by those skilled in the art that the present invention is not limited thereto
Truth of a matter value can for example be preset in a standard, thus the default setting in base station and UE.
Fig. 4 shows a kind of resource allocation cycle of the adjustment rule of the utilization index rule of implementation according to the present invention
The schematic diagram of adjustment.
As shown in Figure 4, it is assumed that the initial value of resource allocation cycle is 100ms, and the truth of a matter value of the rule of exponentials is 2.If
It is not received by any data in initial resource allocation cycle in step 320 base station, then the period is reduced to 50ms
(100ms/2=50ms).
If base station is still not received by any data in the resource allocation cycle of reduced 50ms, continuing should
Period is reduced to 25ms (50ms/2=25ms).
In another implementation of the invention, adjustment rule includes linear programming.In this case, adjusting parameter
Including period modulation coefficient, and adjustresources assignment period further include: it is adjusted based on linear programming and period modulation coefficient
The resource allocation cycle.However, it will be understood by those skilled in the art that the present invention is not limited thereto, adjustment rule and/or
The period modulation coefficient can for example be preset in a standard, thus the default setting in base station and UE.
For example, the period modulation coefficient of linear programming is 0.8 it is still assumed that the initial value of resource allocation cycle is 100ms.
If being not received by any data in initial resource allocation cycle in step 320 base station, which is reduced to
80ms (100ms*0.8=80ms).
If base station is still not received by any data in the resource allocation cycle of reduced 80ms, continuing should
Period is reduced to 64ms (80ms*0.8=64ms).
In another realization of the invention, adjustment rule includes fixed step size rule.In this case, adjusting parameter
Including period modulation step-length, and adjustresources assignment period further include: based on fixed step size rule and period modulation step-length come
Adjust the resource allocation cycle.However, the adjustment is regular it will be understood by those skilled in the art that the present invention is not limited thereto
And/or the period modulation step-length can for example be preset in a standard, thus the default setting in base station and UE.
For example, the period modulation step-length of fixed step size rule is it is still assumed that the initial value of resource allocation cycle is 100ms
10ms.If being not received by any data in initial resource allocation cycle in step 320 base station, which is reduced
To 90ms (100ms-10ms=90ms).
If base station is still not received by any data in the resource allocation cycle of reduced 90ms, continuing should
Period is reduced to 80ms (90ms-10ms=80ms).
On the other hand, if base station receives UL data in the resource allocation cycle, in step 340, base station will be provided
Source assignment period reverts to its initial value.For example, as shown in Figure 4, once base station determine reduced resource allocation cycle (such as
The resource allocation cycle of 25ms) in receive UL data, then next resource allocation cycle is adaptively adjusted to initial value
100ms。
This is because for the transmission of acyclic data, in next cycle after receiving the data again
Secondary a possibility that receiving data transmission, is very low, therefore resource allocation cycle is reverted to (biggish) initial period more has
Benefit.However, resource allocation cycle is anti-in step 340 it will be understood by those skilled in the art that the present invention is not limited thereto
It can gradually be adjusted with the opposite rule of the rule in step 330 or with any other rule to adjustment.
Next, 300 return step 320 of method, base station determines whether receive in resource allocation cycle after the adjustment
UL data.
Further, method 300 can also include step 350, and wherein base station determines that resource allocation cycle adjusted is
It is no to be lower than a lower threshold, and when resource allocation cycle adjusted is lower than the downlink threshold value, directly by resource allocation week
Phase is set as the downlink threshold value (step 360).
In addition, the method 300 of adaptively pre-scheduling resource allocation cycle according to the present invention can be applied to a UE
All business, or can be applied to the certain types of business of one or more of a UE, so that the inhomogeneity of the UE
The business of type has the resource allocation cycle of different adaptively pre-schedulings.
Here, invention has been described for being just adjusted to resource allocation cycle based on primary judgement.So
And the present invention is not limited thereto.It in one implementation, can also include a frequency threshold value in adjustment rule, so that only working as
When base station determines that the number for being not received by UL data reaches the frequency threshold value, the resource allocation cycle is just adjusted.
Similarly, other than step 310, the operation (step 320 ' -360 ') of the side UE is nearly identical with base station side,
Details are not described herein.
In this way, base station side and the side UE have separately been adaptively adjusted money according to identical adjustment rule
Source assignment period.
In addition, base station also needs to send dispatch command to UE, which includes in order to execute the transmission of DL or UL data
Running time-frequency resource and/or Modulation and Coding Scheme (MCS) for the transmission of DL or UL data.
In one implementation, in step 310, base station is by RRC signaling by dispatch command and above-mentioned about resource allocation week
The information of phase sends jointly to UE.In this way, the scheduling of resource between base station and UE is disposably realized.
In another implementation, in each resource allocation cycle, base station passes through Physical Downlink Control Channel (PDCCH) to UE
Send the dispatch command.In this way, channel situation can be considered in each dispatching cycle, to realize more flexible
Scheduling of resource, resource allocation it is more efficient.
In another is realized, in base station in step 310 by RRC signaling by dispatch command and above-mentioned about resource allocation
After the information in period sends jointly to UE, determine whether used running time-frequency resource and/or MCS are changed, and
When used running time-frequency resource and/or MCS change, by PDCCH to running time-frequency resource of the UE transmission comprising update and/or more
The dispatch command of the update of new MCS.In this realization, UE only changes in the running time-frequency resource and/or MCS for receiving update
Become it and transmit used running time-frequency resource and/or MCS, otherwise still using former running time-frequency resource and/or MCS.In this way,
Realize the best compromise of scheduling of resource.
Other side's method 300 is described so that UL is transmitted as an example above, wherein base station based on whether receive UL data and
UE is based on whether have sent UL data to execute the adaptive resource allocation cycle adjustment for UL transmission.
However, it will be understood by those skilled in the art that this method be completely suitable for DL transmission, and for DL transmit, base
Station may be based on whether to have sent DL data and UE may be based on whether to receive DL data execute for DL transmission from
The resource allocation cycle of adaptation adjusts.
In the present invention, a kind of adaptive pre-scheduling scheme with variable resource allocation cycle is proposed.It utilizes
The program, can not only by pre-allocation of resources reduce time delay, and can based on UL receive (for uplink) and
DL emits (for downlink) to adjust the resource allocation cycle of pre-scheduling, and can be suitable for having urgent time delay
The aperiodicity characteristic of the business of demand.
