Embodiment in the application, the every other implementation that those skilled in the art are obtained without making creative work
Example, shall fall in the protection scope of this application.
One hybrid automatic repeat request (hybrid automatic repeat request, HARQ) process refers to
Base station scheduling carries out a data transmission, then receives ACK/NACK feedback informations to base station.In a HARQ process, once
After transmission is sent out, needing the length waited for be round trip delay time (round-trip time, RTT) could determine that transmission next time is to pass
Defeated new data, or carry out the re-transmission of legacy data.During this period of time, base station or terminal cannot stop transmission and in vain etc.
It waits for, it is necessary to other parallel HARQ processes are initiated, to make full use of time-domain resource.Wherein, the number of processes of HARQ is with RTT,
Be exactly propagation delay time and the/base station user equipment (user equipment, UE) processing time it is relevant, RTT is bigger, needs to prop up
For the parallel HARQ processes quantity held to fill up RTT, the quantity of HARQ processes is approximately equal to RTT/TTI.For example, for FDD system and

Consider the processing delay of physical layer, if UE (base station) has sent a data frame by some HARQ process in n-th of subframe,
Base station (UE) could send the confirmation message of the HARQ processes in the n-th+4 subframes, then UE (base station) passes through the HARQ processes
It could continue to send next data frame in the n-th+8 subframes, i.e., the HARQ RTT times are 8ms, therefore are not difficult to obtain HARQ processes
Number is 8.
The embodiment of the present application can be adapted for long term evolution (long term evolution, LTE) and the communication of future 5G
System, can application scenarios be included in group-network construction of the wireless side there are time delay, as between BBU and RRU, between BBU and BBU etc. not
It is optical fiber connection again, i.e., causes the same HARQ processes that can not obtain upper one when carrying out scheduling next time to time delay before existing
The demodulation result of secondary scheduling cannot be scheduled processing according to ACK/NACK results at this time.And in the prior art, it is assumed that last
The demodulation result of scheduling is ACK, therefore the transmission of new data is carried out when dispatching next time, if the true demodulation knot of last scheduling
When fruit is NACK, since the sides UE have emptied the data information of last scheduling, therefore need to wait for RLC ARQ mechanism start come into
Row retransmits, and transmission time is remarkably reinforced, and affects the perception rate of user.
In view of this, this application provides a kind of uplink data scheduling method, for solving demodulation result in the prior art
User caused by reporting not in time perceives the problem of rate loss.
It is distributed base station, the distribution by base station sets involved in the application for ease of understanding in the application
Base station includes BBU and RRU, and there are propagation delay times between BBU and RRU.Based on this, referring to Fig. 1, being carried for the embodiment of the present application
A kind of flow chart of uplink data scheduling method, this method has been supplied to specifically include：
101, UE sends the first scheduling request by RRU to BBU；
When UE needs to send upstream data, for ease of description, in the application, which can be known as to the first agreement
When data cell (protocol data unit, PDU), by RRU to BBU send the first scheduling request, i.e. UE by this first
Scheduling request is sent to RRU, then has RRU to be forwarded to BBU, and wherein first scheduling request is for asking BBU for the first PDU points
With bearing resource, in practical application, which can be to increase request (addition request) message, also may be used
To be other existing message or new information, specific the application does not limit.
In addition, PDU is used to refer to the data unit transmitted between peer layer time, for example, the PDU of physical layer is data bit
(bit), the PDU of data link layer is data frame (frame), and the PDU of network layer is data packet (packet), the PDU of transport layer
It is data segment (segment), other higher level PDU are message (message).
102, BBU sends first message by RRU to UE；
After BBU receives the first scheduling request, in response to first scheduling request, it is forwarded to UE via RRU and sends first
Message, which includes that UE sends resource scheduling information used in the first PDU, used in the first PDU of the transmission
Resource scheduling information is used to indicate that the position of radio resource, the resource scheduling information can carry promising UE and transmit for the first time to UE
Resource block sequence number (resource block index, the RB index) sequence number of one PDU distribution or the positions RB, and modulation
Coding mode (Modulation and Coding Scheme, MCS).Wherein the selection of MCS can be by BBU by measuring UE hairs
Serve row transmission data acquisition, such as according to the uplink reference signals carried in data do measurement or other signals, specifically this
Place does not limit.
Optionally, the scheduling of resource period that BBU configurations are may also include in the resource scheduling information, in practical application, the money
Source dispatching cycle is optional parameters, if the scheduling of resource period is not informed that BBU is every time before scheduling resource to UE by the BBU
At the time of all needing to notify BBU scheduling resources to UE.
Optionally, which can be UL grant corresponding with UE, can also be other existing message or new
Message, specific the application do not limit.Wherein, UL grant can carry can by the predetermined information of UE unique identifications and
It is assigned to the private resource that the UE sends upstream data, and modulation and coding strategy (modulation and coding
Scheme, MCS) etc. scheduling informations so that UE can identify the UL grant of oneself according to predetermined information, and in the UL
Upstream data is sent on the private resource specified in grant.In addition, the UL grant can come from the PDCCH of dynamic dispatching, or
From RAR, or by being semi-statically configured.
It should be noted that due between BBU and RRU there are propagation delay time, in the application, if BBU uses the at the T moment
One HARQ processes carry out the new biography scheduling of PDU1, and first message is sent to RRU, RRU in T+s receptions to the first message,
And then it is transmitted to UE, in the application, it is assumed that propagation delay time is not present between RRU and UE, therefore UE is also in T+s receptions to first
Message, wherein s are the propagation delay time between BBU and RRU, and in practical application, the value of s can be 2ms, 3ms or 4ms
Deng not limiting specifically herein.
103, UE sends the first PDU by RRU to BBU；
UE obtains the money for being used for transmission the first PDU for including in the first message after T+s receptions to first message
Source scheduling information, since the resource scheduling information includes the positions MCS and RB index or RB, therefore UE believes from the scheduling of resource
Content in breath determines the time-frequency location and MCS of the radio resource of BBU distribution, therefore UE is existed based on the resource scheduling information
At running time-frequency resource specified BBU, the first PDU is sent to BBU according to the MCS of BBU distribution, it should be noted that the sides UE there is also
Processing delay p, i.e. UE send the first PDU to RRU after T+s receptions to first message, at the T+s+p moment so that RRU exists
After T+s+p receptions to the first PDU, the first PDU is forwarded to BBU, it is to be understood that BBU receives the first PDU
At the time of be T+2s+p.In addition, being provided in agreement, the processing delay p of the sides UE can be 4ms.
104, BBU sends second message by RRU to UE；
As shown in Fig. 2, being a kind of possible HARQ processes schematic diagram provided by the present application, wherein number 1-8 expressions respectively follow
8 parallel HARQ processes in the ring period, each parallel HARQ processes are mutual indepedent, and letter A confirms response for indicating
For indicating negative response NACK, base station is retransmitted or is transmitted to UE transmission datas, and according to the feedback of UE by ACK, alphabetical N
New data, as shown, in first cycle period, base station by process 3 to UE transmission datas, and in second circulating cycle
Receive the ACK of UE feedbacks before phase, therefore base station sends new data by process 3 in second cycle period to UE, and the
The NACK of UE feedbacks is received before three cycle periods, therefore base station is sent newly by process 3 to UE in third cycle period
The re-transmission data of data.
Therefore, because there are propagation delay times between BBU and RRU, and there are processing delay for the sides UE, therefore logical at the T moment in BBU
After crossing the first process transmission first message, in next cycle period, BBU possibly can not obtain the decoding at T moment as a result, therefore not
Processing can be scheduled.Therefore, BBU sends second message by RRU at the T+m moment to UE, and wherein m is the cycle of HARQ processes
In the period, in practical application, the value of m can be 8ms either 10ms or other numerical value, not limit herein specifically.And this
Two message carry for the first PDU acquiescence decoding as a result, and acquiescence decoding result be ACK, and second message include send
Resource scheduling information used in 2nd PDU, it should be noted that before sending the second message, BBU is sent out by receiving UE
The second scheduling request sent to distribute bearing resource for the 2nd PDU, and will configure and provided used in the 2nd PDU for sending
Source scheduling information is carried in second message, and the process is similar with the step 101 to 102 in the application, specifically no longer superfluous herein
It states.
Optionally, which may be new biography grant corresponding with UE, can also be other existing message or
New information, specific the application do not limit.
It is understood that BBU is forwarded to UE at the T+m moment via RRU sends second message, due between BBU and RRU
Propagation delay time s, therefore RRU receives the second message at the T+m+s moment, and be forwarded to UE, and UE the T+m+s moment receive this second
After message, although including the acquiescence decoding to the first PDU as a result, UE empties first not according to acquiescence decoding result
The data of PDU.
105, BBU couples of the first PDU is modulated decoding and handles to obtain true decoding result；
After UE sends the first PDU by RRU to BBU, BBU receives the first PDU at the T+2s+p moment, to the first PDU
Decoding processing is modulated to obtain really decoding result, it is to be understood that in order to improve data transmission efficiency, reduce error code
Rate, in practical application, the first PDU can successively be encoded, be modulated, mapped framing, is fast by the UE in transmitting terminal, that is, the application
Fast inverse Fourier transform and plus the operations such as cyclic prefix (cyclic prefix, CP), be then to receiving terminal by transmission
BBU in the application, it is therefore, corresponding, after BBU receives the first PDU of UE transmissions, to the first PDU that receives successively into
Row goes CP, Fast Fourier Transform (FFT), data pick-up, channel estimation, equilibrium, demodulation decoding processing.In the application, after coding
The first PDU be modulated decoding processing existing technological means may be used, specific the application repeats no more.
It should be noted that in practical application, it can be 2.5ms~3.75ms that the process of modulation decoding processing, which takes,
Or other durations, it does not limit herein specifically.
106, BBU sends third message by RRU to UE；
BBU is obtained after really decoding result, can increase true decoding knot newly in third message according to the true decoding result
Fruit instruction (operation needs agreement support or privatization agreement), such as this can be carried by the specific bit in third message
The information of true decoding result instruction e.g. when the specific bit is 0, indicates that decoding is correct, that is, is used for the feedback message of the first PDU
For ACK；When the specific bit is 1, decoding failure is indicated, that is, the feedback message for being used for the first PDU is NACK.
In addition, when if decoding result indicates decoding failure, BBU also needs this time scheduling data volume compensating back buffering area, and
Carry out the retransfer scheduling of PDU1.It is to be understood that the sides BBU safeguard that a buffering area, the buffering area may include dispatching UE request hairs
Send data required scheduling data volume, BBU is determined the length or size of the complete required resource block of data dispatch, can be with
Understand, also needs to be scheduled again if scheduling error.For example, as UE asks to send 100 data, BBU tune
After having spent wherein 10 data, buffering area there remains 90 scheduling data volumes, if 10 scheduled data decodings are correct, after
What continuous scheduling UE requests were sent is left 90 data；If 10 scheduled data decoding errors, that is, indicate to send failure, then
BBU also needs to dispatch 10 data, thus by the scheduling data volume for dispatching used in 10 data compensate back buffering area with
It is dispatched next time.Further include retransmitting scheduling of resource letter used in the first PDU therefore when decoding failure, in third message
Breath can also be other existing message or new information in addition, the third message may be re-transmission grant corresponding with UE,
It does not limit herein specifically.
In addition, if really decoding result indicates that decoding is correct, BBU carries out conventional operation, such as in next HARQ
Cycle period pass through the first HARQ processes carry out new data scheduling.
It should be noted that if the true decoding result that BBU is obtained is that decoding is correct, BBU increases newly true in third message
Real decoding result be designated as can selection operation, i.e. UE is after the preset time period for receiving third message, if not receiving information yet to refer to
Show that BBU decodes the first PDU failures, then UE confirms the above-mentioned as true decoding of acquiescence decoding result as a result, i.e. based on the first PDU's
It is fed back to ACK.
To sum up, third message is sent to UE by BBU by the first HARQ processes at the T+A*m moment via RRU, so that UE
Determine whether to empty the data of the first PDU according to the true decoding result instruction in the third message, wherein A is whole more than 1
Number.
107, UE is according to the first PDU of third retransmitting message；
Third message is sent to UE by BBU at the T+A*m moment by RRU, is deposited based on propagation delay time s between BBU and RRU
In, UE in T+A*m+s receptions to the third message, if the true decoding result instruction entrained by third message indicates decoding
Fail, then resource scheduling information retransmits the first PDU retained used in the first PDU of re-transmission that UE includes according to third message
Data.
108, UE empties the data of the first PDU according to third message.
Third message is sent to UE by BBU at the T+A*m moment by RRU, is deposited based on propagation delay time s between BBU and RRU
In, UE in T+A*m+s receptions to the third message, if the true decoding result instruction entrained by third message indicates decoding
