Description

A kind of method and device determining that retransfer scheduling monitors number of times
Technical field
The present invention relates to the communications field, more particularly to a kind of method and dress determining that retransfer scheduling monitors number of times Put.
Background technology
Long Term Evolution (long term evolution, lte) communication system have flexible data dispatch and Transmission mechanism, when terminal needs to carry out transmitting uplink data, needs and to award for its dynamically distributes by base station Power transmitting uplink data resource.
Specifically, refering to shown in Fig. 1 and Fig. 2, there is no transmitting uplink data resource authorization in terminal In the case of, the process that terminal initiates transmitting uplink data includes:
Step 200: terminal sends uplink scheduling request (schedule request, sr), request base station is divided Join upstream data transfer resource, subframe 2 in such as Fig. 1.
Step 210: after base station receives the uplink scheduling request of terminal, according to Current resource dispatch situation, with And protocol contents determine corresponding uplink authorization subframe, and carry out up awarding in this uplink authorization subframe for terminal Weigh (ul grant) it is intended that terminal sends the resource of upstream data, including time domain and frequency domain position, and In form, such as modulation system etc., such as Fig. 1, the corresponding uplink authorization subframe of subframe 2 is subframe 8.
Step 220: after terminal receives the uplink authorization of base station, according in uplink authorization instruction time domain and Frequency domain position and form, send upstream data bag, subframe 12 in such as Fig. 1.
Step 230: terminal, after completing upstream data transmission, needs to wait the feedback of base station side, to determine Carry out uplink retransmission and still monitor retransfer scheduling, subframe 18 in such as Fig. 1.
Wherein, the uplink retransmission mentioned in step 230 includes synchronous self-adapting and retransmits and synchronous non-self-adapting weight Pass two ways.Wherein, " synchronous " subframe position representing re-transmission is fixed, and that is, time-domain position is fixed." from Adapt to retransmit " represent in retransmission processes and the frequency domain that transmission uses can be changed according to actual channel condition information Resource and form, carrying out adaptive retransmission every time needs base station to send retransfer scheduling, and instruction terminal retransmits and uses Frequency domain resource and form, terminal detect base station transmission retransfer scheduling control signaling after trigger self adaptation weight Pass." non-self-adapting re-transmission " represents frequency domain resource and form and initial transmission use used in retransmission processes Frequency domain resource frequency domain resource that it is not necessary to base station send control signaling instruction use identical with form and lattice Formula, incorrect reception instruction (nack) receiving base station feedback in terminal triggers non-self-adapting afterwards automatically Retransmit.
Further, if terminal receives nack or retransfer scheduling then it represents that base station does not correctly connect Receive the upstream data that terminal sends, terminal needs to initiate to retransmit.And if terminal receives ack, such as Fig. 1 Shown in middle subframe 18, do not indicate that the upstream data that this terminal sends is coated base station and is properly received, base station is still yet Need according to agreement in the corresponding subframe of transmission process of this upstream data bag, subframe 28, son in such as Fig. 1 Frame 38 etc., dispatches adaptive retransmission, and terminal need to be in corresponding subframe, subframe 28, subframe in such as Fig. 1 38 etc., monitor the retransfer scheduling control signaling that base station sends.
Terminal only receives base station and dispatches new data in the transmission process of this upstream data bag, or reaches During the maximum monitoring number of times of upstream data bag, just represent data receiver success.
Wherein, the number of times of monitoring of terminal monitoring base station scheduling depends on the number of transmissions that base station configures, and monitors secondary Number=the number of transmissions -1, and the number of transmissions is allocated to terminal by base station by space interface signaling.
According to said process, terminal can close part transceiver assembly and module in non-snoop subframe, Make itself to be operated in low-power consumption mode, to reach the purpose saved electricity, extend battery working time.Existing In technology, terminal can use one or more optimised power consumption scheme in real work, such as discontinuously connects Receive the target that schemes such as (discontinuous reception, drx) realizes low-power consumption.
Specifically, taking drx scheme as a example illustrate, terminal can assess low-power consumption mode duration in advance, Close the duration of part transceiver assembly and module.And can assembly finally be closed, depending on low-power consumption The comparative result of the closed minimum interval of pattern duration and the determination of assembly self-characteristic.Wherein, low work( Consumption pattern duration, is set to tsleep, the closed minimum interval that assembly a self-characteristic determines, it is set to tminIf, tsleepLess than tmin, then assembly a cannot be turned off to reach the purpose saving electricity.If tsleepMore than tmin, then assembly a can be closed.Therefore, with tsleepIncrease, can close Assembly gradually increases.Work as tsleepReach maximum time thresholding, most of assembly can be de-energized closing, eventually End lower power consumption, to floor level, enters deep sleep.
From the foregoing, it will be observed that the low-power consumption mode duration that terminal is estimated determines closable component count, further Determine the effect of Save power consumption.But, in existing transmitting uplink data scheme, terminal monitoring retransmits Scheduling will interrupt dormancy period repeatedly, by one section of longer tsleepIt is cut to the shorter dormancy time of multistage, As shown in figure 3, lead to the saving power consumption that drx brings effect less, and open assembly and close assembly this Body can bring about some extra preparations, and terminal is waken up from resting state the subframe of monitoring retransfer scheduling Before and after several subframes all in working condition, ultimately resulting in terminal works may in the duration of low-power consumption mode Close to zero.

Specific embodiment
In order to solve to lead because terminal monitoring retransfer scheduling interrupts dormancy period repeatedly present in prior art Cause the terminal low-power consumption time shorter, the poor problem of power savings, the invention provides a kind of determine that re-transmission is adjusted The method that degree monitors number of times, the method is: terminal is according to the current each channel quality parameter measurement obtaining Value, determines the corresponding prediction measured value range of each channel quality parameter measured value respectively；Terminal is according to every One channel quality parameter measured value corresponding prediction corresponding retransfer scheduling of measured value range is monitored number of times and is built View value, determines that the corresponding retransfer scheduling of each channel quality parameter measured value monitors number of times recommended value respectively； Terminal is monitored number of times recommended value from all retransfer schedulings currently obtaining, and chooses the maximum retransfer scheduling of value Monitor number of times recommended value and monitor number of times as itself retransfer scheduling.
Below in conjunction with the accompanying drawings the preferred embodiment of the present invention is illustrated.
In pretreatment stage, terminal is directed to each of specified measurement object and first carries out multiple measurement respectively in advance, Obtain each self-corresponding multiple prediction measured value range of each measurement object respectively, and determine each respectively The individual prediction corresponding retransfer scheduling of measured value range monitors number of times recommended value.
Wherein, measurement object is channel quality parameter.
Refering to shown in Fig. 4, in pretreatment stage, terminal first carries out in advance for any one measurement object Repeatedly measure, obtain corresponding multiple prediction measured value range, and determine that each predicts measured value respectively The detailed process that the corresponding retransfer scheduling of scope monitors number of times recommended value is as follows:
Step 400: terminal first carries out many in whole cell coverage area in advance for any one measurement object Secondary measurement, obtains minimum measured value and the greatest measurement of any one measurement object.
Specifically, measurement object here is probably Reference Signal Received Power (reference signal Received power, rsrp), Signal to Interference plus Noise Ratio (signal to interference plus noise Ratio, sinr) or the bit error rate etc..For any one measurement object, anolog base station ring can be based on Border, or really base-station environment measures, and the measurement result of acquisition is repeatedly measured by execution, obtain Obtain minimum measured value and the greatest measurement of any one measurement object.Wherein, minimum measured value is multiple survey The measured value of cell edge in amount, greatest measurement is the measured value of the fabulous point of MPS process in multiple measurement.
For example, in the multiple measurement for rsrp, minimum measured value is -110db, and greatest measurement is -80db.
Step 410: terminal according to default step-length, from the minimum measured value of any one measurement object with Several sampled measurements are selected in the measured value range that big measured value is constituted；
As above example, in the multiple measurement for rsrp, minimum measured value is -110db, greatest measurement For -80db, so that default step-length is as 2db as a example, the measured value that constitutes from minimum measured value and greatest measurement Scope, [- 110, -80], select several sampled measurements, { -110, -108 ..., -82, -80 }, Totally 16 sampled measurements.
Step 420: terminal is based respectively on the corresponding channel circumstance of each sampled measurement and initiates uplink service, And the result based on corresponding uplink service determines that corresponding re-transmission of each sampled measurement is adjusted respectively Degree monitors number of times recommended value.
Specifically, taking sampled measurement a as a example, can adopt but be not limited to following terminal and determine sampled measurements The method that the corresponding retransfer scheduling of value a monitors number of times recommended value.
Terminal is based on the corresponding channel circumstance of sampled measurement a and initiates uplink service, and counts in preset duration The number of retransmissions that in uplink service, each upstream data bag actually occurs, as the result of uplink service. Assume, in preset duration, to send m upstream data bag altogether, record the actual heavy of each upstream data bag Pass number of times ri, obtain { r1, r2, r3..., rm, as the corresponding uplink service of sampled measurements point a Result.
Further, the result based on uplink service for the terminal, and default packet loss sensitivity value, Determine that the corresponding retransfer scheduling of sampled measurement a monitors number of times recommended value.Here default packet loss is sensitive Degree value p refers to that retransfer scheduling monitors number of times recommended value niMore than { r in the result of uplink service1, r2, r3..., rmIn p% data value, the value of p is any number in 0～100.Typically, p=100 Represent niThe maximum retransmission actually occurring for the corresponding channel circumstance of sampled measurement a, i.e. { r1, r2, r3..., rmIn maximum.
Step 430: terminal monitors number of times recommended value according to the corresponding retransfer scheduling of each sampled measurement, Determine the corresponding multiple prediction measured value range of any one measurement object, and determine multiple pre- further respectively Survey each of measured value range prediction corresponding retransfer scheduling of measured value range and monitor number of times recommended value.
Wherein, terminal monitors number of times recommended value according to the corresponding retransfer scheduling of each sampled measurement, determines The corresponding multiple prediction measured value range of any one measurement object, can adopt but be not limited to following side Method, this is specifically described as a example sentencing measurement object x, and the minimum measured value of measurement object x is x1, Greatest measurement is x13, selects several sampled measurements, { x1, x2 ..., x12, x13 }, Totally 13 sampled measurements, and supervised according to the corresponding retransfer scheduling of each sampled measurement according to each Listen number of times recommended value, generate the scattergram that retransfer scheduling monitors number of times recommended value, refering to shown in Fig. 6, to adopt Sample measured value is abscissa, monitors number of times recommended value as vertical coordinate with retransfer scheduling, generates retransfer scheduling and monitors Number of times recommended value scattergram.
Terminal monitors the scattergram of number of times recommended value according to retransfer scheduling, determines that retransfer scheduling monitors number of times suggestion Value changes the corresponding sampled measurement of point, shown in Fig. 5 midpoint a, point b and point c.
Terminal is monitored number of times recommended value according to retransfer scheduling and is changed the corresponding sampled measurement of point, and minimum survey Value and greatest measurement, determine the corresponding multiple prediction measured value range of measurement object x.
As shown in figure 5, the prediction measured value range of last measurement object x obtaining be [x1, x4), [x4, X7), [x7, x10), [x10 ,+∞), and each prediction corresponding retransfer scheduling of measured value range Monitor number of times recommended value as shown in table 1.

Additionally, being directed to each of specified measurement object in terminal to first carry out multiple measurement respectively in advance, obtain respectively Obtain each self-corresponding multiple prediction measured value range of each measurement object, and determine each prediction respectively After the corresponding retransfer scheduling of measured value range monitors number of times recommended value, terminal is by each measurement object each Corresponding multiple prediction measured value range, and each prediction measured value range corresponding retransfer scheduling monitoring Number of times recommended value, sends to base station.
Therefore, in business transmitting procedure, base station can be according to each letter of the current acquisition of terminal to report Road mass parameter measured value, by inquiring about each self-corresponding multiple prediction measured value models of each measurement object Enclose, and each prediction corresponding retransfer scheduling of measured value range monitors number of times recommended value, dynamic adjustment weight Pass the number of times of scheduling, the strategy of real-time adjustment retransfer scheduling.
Refering to the idiographic flow shown in Fig. 6, determining retransfer scheduling monitoring number of times it is:
Step 600: terminal, according to the current each channel quality parameter measured value obtaining, determines every respectively The corresponding prediction measured value range of one channel quality parameter measured value.
Specifically, terminal is according to the current each channel quality parameter measured value obtaining, can be here to One item missing channel quality parameter measured value, determines the corresponding prediction of each channel quality parameter measured value respectively Measured value range, for example, as shown in table 2, rsrpmeas=-80db, sinrmeas=15db, then respectively really Both corresponding prediction measured value range fixed, rsrpmeasCorresponding prediction measured value range be [- 88 ,+∞), sinrmeasCorresponding prediction measured value range be [13.5 ,+∞).
Table 2

[-96,-88) [7.5,13.5) 2
[- 104, -96) [1.5,7.5) 3
[- 110, -104) [-3,1.5) 4
Step 610: terminal is according to each channel quality parameter measured value corresponding prediction measured value range pair The retransfer scheduling answered monitors number of times recommended value, determines that each channel quality parameter measured value is corresponding heavy respectively Pass scheduling and monitor number of times recommended value.
Specifically, the corresponding retransfer scheduling of measured value range is predicted according to each obtaining in pretreatment stage Monitor number of times recommended value, determine that the corresponding retransfer scheduling of each channel quality parameter measured value is monitored time respectively Number recommended values, for example, as shown in table 2, the prediction measured value range of rsrp be [- 88 ,+∞) corresponding heavy Pass scheduling monitor the prediction measured value range that number of times recommended value is 1, sinr be [13.5 ,+∞) corresponding re-transmission adjusts It is 1, therefore, rsrp that degree monitors number of times recommended valuemeasIt is 1 that corresponding retransfer scheduling monitors number of times recommended value, sinrmeasIt is 1 that corresponding retransfer scheduling monitors number of times recommended value.
Step 620: terminal is monitored number of times recommended value from all retransfer schedulings currently obtaining, and chooses value Maximum retransfer scheduling is monitored number of times recommended value and is monitored number of times as itself retransfer scheduling.
Specifically, the rsrp as above obtaining in examplemeasIt is 1 that corresponding retransfer scheduling monitors number of times recommended value, sinrmeasIt is 1 that corresponding retransfer scheduling monitors number of times recommended value, and therefore itself retransfer scheduling monitoring number of times is 1.
Again for example, rsrpmeasIt is 2, sinr that corresponding retransfer scheduling monitors number of times recommended valuemeasCorresponding It is 1 that retransfer scheduling monitors number of times recommended value, then choose the maximum retransfer scheduling monitoring number of times recommended value of value and make Monitor number of times for itself retransfer scheduling, that is, itself retransfer scheduling monitors number of times is 2.
Therefore, terminal can be according to the current each channel quality parameter measured value obtaining, real-time adjustment Retransfer scheduling monitors number of times, and determines that final re-transmission is adjusted according to the poor result of channel quality parameter measurement Degree monitors number of times.
Further, after terminal determines that itself retransfer scheduling monitors number of times, terminal is monitored according to retransfer scheduling Number of times arranges itself and enters the subframe of park mode and corresponding sleep time.
Under prior art, in actual business transmitting procedure, terminal is receiving the ack of base station feedback Still the purpose monitoring retransfer scheduling afterwards is to avoid flase drop feedback information.According to agreement, monitor retransfer scheduling Number of times subtract 1 for the number of transmissions, the number of transmissions is by the unified configuration in base station.The number of transmissions configuration be one Big value, the number of transmissions of base station actual schedule is likely to less than this Configuration Values with the change of channel quality, but It is but to actually occur number of times that retransfer scheduling monitors number of times, i.e. fixed value, and the number of transmissions subtracts 1.
Therefore, for the transmitting procedure of a upstream data bag, regardless of channel quality, terminal is required for Monitor maximum times, unless base station is scheduling in this process.But it is true that the probability of terminal flase drop and Present channel environment has very big relation, and retransfer scheduling is monitored number of times and should be carried out with the change of channel quality Dynamic adjustment.Under the preferable environment of channel condition, terminal occurs the probability of flase drop relatively low, does not substantially have Retransmit, end side can reduce retransfer scheduling and monitor number of times.Gradually it is deteriorated with channel condition, terminal occurs by mistake The probability of inspection increases, and can suitably increase retransfer scheduling and monitor number of times.Using the method for the present invention, by working as The real-time judge of front channel quality, is capable of retransfer scheduling is monitored with the dynamic adjustment of number of times.
