Description

A kind of determining retransfer scheduling monitors the method and device of number
Technical field
The present invention relates to the communications fields, and the method and device of number is monitored more particularly to a kind of determining retransfer scheduling.
Background technique
Long term evolution (Long Term Evolution, LTE) communication system has flexible data dispatch and conveyer System needs to dynamically distribute by base station for it and authorization transmitting uplink data provides when terminal needs to carry out transmitting uplink data Source.
Specifically, refering to fig. 1 and shown in Fig. 2, in the case where terminal there is no transmitting uplink data resource authorization, eventually End initiate transmitting uplink data process include:
Step 200: terminal sends uplink scheduling request (Schedule Request, SR), and upper line number is distributed in request base station According to transfer resource, subframe 2 as shown in figure 1.
Step 210: after base station receives the uplink scheduling request of terminal, according in Current resource dispatch situation and agreement Hold and determine corresponding uplink authorization subframe, and be that terminal carries out uplink authorization (UL Grant) in the uplink authorization subframe, specifies Terminal sends the resource of upstream data, including time domain and frequency domain position and format, such as modulation system, as shown in figure 1 subframe 2 Corresponding uplink authorization subframe is subframe 8.
Step 220: after terminal receives the uplink authorization of base station, according to the time domain and frequency domain position indicated in uplink authorization And format, upstream data packet is sent, as shown in figure 1 subframe 12.
Step 230: terminal needs to wait the feedback of base station side after completing upstream data and sending, to determine to carry out uplink It retransmits or monitors retransfer scheduling, as shown in figure 1 subframe 18.
Wherein, the uplink retransmission mentioned in step 230 includes that synchronous self-adapting retransmits and two kinds of synchronous non-self-adapting re-transmission Mode.Wherein, " synchronization " indicates that the subframe position retransmitted is fixed, i.e., time-domain position is fixed." adaptive retransmission " expression retransmitted The frequency domain resource and format that transmission uses can be changed in journey according to actual channel state information, carry out adaptive retransmission every time Base station is needed to send retransfer scheduling, instruction terminal retransmits the frequency domain resource used and format, and terminal detects the weight that base station is sent Adaptive retransmission is triggered after passing scheduling control signaling." non-adaptive re-transmission " indicates frequency domain resource and lattice used in retransmission processes Formula is identical with frequency domain resource and format that initial transmission uses, does not need base station and sends control signaling the frequency domain that uses of instruction Resource and format indicate (NACK) non-adaptive re-transmission of automatic trigger afterwards in the incorrect reception that terminal receives base station feedback.
Further, if terminal receives NACK or retransfer scheduling, then it represents that base station is not properly received terminal transmission Upstream data, terminal need initiate retransmit.And if terminal receives ACK, as shown in figure 1 shown in subframe 18, the end is not indicated yet End send upstream data coating base station be properly received, base station there is still a need for according to agreement the upstream data packet transmission process pair In the subframe answered, subframe 28, subframe 38 etc., dispatch adaptive retransmission, terminal need to be in corresponding subframe, as shown in figure 1 as shown in figure 1 Subframe 28, subframe 38 etc. monitor the retransfer scheduling control signaling that base station is sent.
Terminal only receives base station and dispatches new data in the transmission process of the upstream data packet, or reaches line number When monitoring number according to the maximum of packet, data receiver success is just indicated.
Wherein, the number of transmissions of terminal monitoring base station scheduling monitored number and depend on base station configuration, monitors number=biography Defeated number -1, and the number of transmissions is allocated to terminal by space interface signaling by base station.
According to the above process it is found that terminal can close part transceiver assembly and module in non-snoop subframe, make itself Work is in low-power consumption mode, to achieve the purpose that save electricity, extend battery working time.In the prior art, terminal is in reality One or more optimised power consumption scheme can be used in work, such as discontinuously receive (Discontinuous reception, ) etc. DRX schemes realize the target of low-power consumption.
Specifically, being illustrated by taking DRX scheme as an example, terminal can assess low-power consumption mode duration, i.e. close portion in advance Divide the duration of transceiver assembly and module.And can component finally be closed, and depend on low-power consumption mode duration and component itself The comparison result for closing minimum interval that characteristic determines.Wherein, low-power consumption mode duration is set as Tsleep, component A itself What characteristic determined closes minimum interval, is set as TminIf TsleepLess than Tmin, then component A can not be turned off to reach Save the purpose of electricity.If TsleepGreater than Tmin, then component A can be closed.Therefore, with TsleepIncrease, Ke Yiguan The component closed gradually increases.Work as TsleepReach maximum time thresholding, most of component can be powered down closing, and power consumption of terminal reduces To floor level, into 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 retransfer scheduling will be interrupted repeatedly not It sleeps the period, by one section of longer TsleepIt is cut to the shorter dormancy time of multistage, as shown in figure 3, DRX bring is caused to save function The effect of consumption is smaller, and opens component and close component itself and can bring about some additional preparations, and terminal is from dormant state Wake up monitoring retransfer scheduling subframe the several subframes in front and back all in working condition, eventually lead to terminal works in low-power consumption The duration of mode is possibly close to zero.

Specific embodiment
In order to solve existing in the prior art to lead to terminal since terminal monitoring retransfer scheduling interrupts dormancy period repeatedly The low-power consumption time is shorter, the poor problem of power savings, the present invention provides a kind of method that determining retransfer scheduling monitors number, This method are as follows: terminal determines each single item channel quality ginseng according to each single item channel quality parameter measured value currently obtained respectively The corresponding prediction measured value range of number measured value；Terminal is according to the corresponding prediction measured value of each single item channel quality parameter measured value The corresponding retransfer scheduling of range monitors number recommended value, determines that the corresponding re-transmission of each single item channel quality parameter measured value is adjusted respectively Degree monitors number recommended value；Terminal is monitored in number recommended value from all retransfer schedulings currently obtained, and it is maximum to choose value Retransfer scheduling monitors number recommended value as itself retransfer scheduling and monitors number.
The preferred embodiment of the present invention is illustrated with reference to the accompanying drawing.
In pretreatment stage, terminal first carries out multiple measurement for each specified measurement object in advance respectively, obtains respectively The corresponding multiple prediction measured value ranges of each measurement object are obtained, and determine each prediction measured value range respectively Corresponding retransfer scheduling monitors number recommended value.
Wherein, measurement object is channel quality parameter.
As shown in fig.4, terminal first carries out multiple survey for any one measurement object in advance in pretreatment stage Amount obtains corresponding multiple prediction measured value ranges, and determines that each corresponding re-transmission of prediction measured value range is adjusted respectively Degree monitors number recommended value, and detailed process is as follows:
Step 400: terminal first carries out multiple measurement for any one measurement object in advance in entire cell coverage area, Obtain the minimum measured value and greatest measurement of any one measurement object.
Specifically, measurement object here may be Reference Signal Received Power (Reference signal received Power, RSRP), Signal to Interference plus Noise Ratio (Signal to Interference plus Noise Ratio, SINR) Or bit error rate etc..For any one measurement object, it can be based on anolog base station environment, or true base-station environment carries out Measurement, and by executing the measurement result that repeatedly measurement obtains, obtain the minimum measured value and maximum of any one measurement object Measured value.Wherein, minimum measured value is the measured value of cell edge in repeatedly measurement, and greatest measurement is cell in repeatedly measurement Cover the measured value of fabulous point.
For example, minimum measured value is -110dB in the multiple measurement for RSRP, greatest measurement is -80dB.
Step 410: terminal is according to preset step-length, from the minimum measured value and greatest measurement of any one measurement object Several sampled measurements are selected in the measured value range constituted；
Example as above, in the multiple measurement for RSRP, minimum measured value is -110dB, and greatest measurement is -80dB, with For preset step-length is 2dB, the measured value range constituted from minimum measured value and greatest measurement, [- 110, -80] are selected 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 is based on The processing result of corresponding uplink service determines that the corresponding retransfer scheduling of each sampled measurement monitors number recommended value respectively.
Specifically, can use but be not limited to pair that following terminal determines sampled measurement A by taking sampled measurement A as an example The method that the retransfer scheduling answered monitors number recommended value.
Terminal is based on the corresponding channel circumstance of sampled measurement A and initiates uplink service, and counts upper industry in preset duration The number of retransmissions that each upstream data packet actually occurs in business, the processing result as uplink service.Assuming that in preset duration, M upstream data packet is sent altogether, records the practical number of retransmissions R of each upstream data packeti, obtain { R1, R2, R3..., RM, make For the corresponding uplink service processing result of sampled measurements point A.
Further, processing result and preset packet loss susceptibility value of the terminal based on uplink service, determination are adopted The corresponding retransfer scheduling of sample measured value A monitors number recommended value.Here preset packet loss susceptibility value P refers to that re-transmission is adjusted Degree monitors number recommended value NiGreater than { R in the processing result of uplink service1, R2, R3..., RMIn P% data value, the value of P For any number in 0~100.Typically, P=100 indicates NiIt is actually occurred most for the corresponding channel circumstance of sampled measurement A Big number of retransmissions, i.e. { R1, R2, R3..., RMIn maximum value.
Step 430: terminal monitors number recommended value according to the corresponding retransfer scheduling of each sampled measurement, determines any The corresponding multiple prediction measured value ranges of one measurement object, and further determine respectively each in multiple prediction measured value ranges The corresponding retransfer scheduling of a prediction measured value range monitors number recommended value.
Wherein, terminal monitors number recommended value according to the corresponding retransfer scheduling of each sampled measurement, determines any one The corresponding multiple prediction measured value ranges of a measurement object, can use but method not limited to the following, this sentences measurement object X For be specifically described, the minimum measured value of measurement object X is X1, greatest measurement X13, selects several samplings and surveys Magnitude, { X1, X2 ..., X12, X13 }, totally 13 sampled measurements, and it is corresponding according to each sampled measurement according to each Retransfer scheduling monitor number recommended value, generate retransfer scheduling monitor number recommended value distribution map, as shown in fig.6, to adopt Sample measured value is abscissa, monitors number recommended value as ordinate using retransfer scheduling, generates retransfer scheduling and monitor number recommended value Distribution map.
Terminal monitors the distribution map of number recommended value according to retransfer scheduling, determines that retransfer scheduling is monitored number recommended value and changed Shown in the corresponding sampled measurement of point, the midpoint Fig. 5 A, point B and point C.
Terminal according to retransfer scheduling monitor number recommended value change the corresponding sampled measurement of point and minimum measured value and Greatest measurement determines the corresponding multiple prediction measured value ranges of measurement object X.
As shown in figure 5, the prediction measured value range of the measurement object X finally obtained be [X1, X4), [X4, X7), [X7, X10), [X10 ,+∞) and each corresponding retransfer scheduling of prediction measured value range to monitor number recommended value as shown in table 1.

In addition, first carrying out multiple measurement in advance respectively for each specified measurement object in terminal, obtain respectively each The kind corresponding multiple prediction measured value ranges of measurement object, and determine that each prediction measured value range is corresponding respectively After retransfer scheduling monitors number recommended value, terminal by the corresponding multiple prediction measured value ranges of each measurement object, And each corresponding retransfer scheduling of prediction measured value range monitors number recommended value, is sent to base station.
Therefore, in business transmission process, each single item channel quality currently obtained that base station can be reported according to terminal Measured value of parameters, by inquiring the corresponding multiple prediction measured value ranges of each measurement object and each prediction The corresponding retransfer scheduling of measured value range monitors number recommended value, and dynamic adjusts the number of retransfer scheduling, and adjustment in real time, which retransmits, adjusts The strategy of degree.
As shown in fig.6, determining that retransfer scheduling monitors the detailed process of number are as follows:
Step 600: terminal determines each single item channel according to each single item channel quality parameter measured value currently obtained respectively The corresponding prediction measured value range of mass parameter measured value.
Specifically, terminal can be at least one according to each single item channel quality parameter measured value currently obtained here Channel quality parameter measured value determines the corresponding prediction measured value range of each single item channel quality parameter measured value respectively, for example, As shown in table 2, RSRPmeas=-80dB, SINRmeas=15dB then determines the corresponding prediction measured value range of the two respectively, RSRPmeasCorresponding prediction measured value range be [- 88 ,+∞), SINRmeasCorresponding prediction measured value range be [13.5 ,+ ∞)。

[-96,-88) [7.5,13.5) 2
[- 104, -96) [1.5,7.5) 3
[- 110, -104) [-3,1.5) 4
Step 610: terminal is corresponding heavy according to the corresponding prediction measured value range of each single item channel quality parameter measured value It passes scheduling and monitors number recommended value, determine that the corresponding retransfer scheduling of each single item channel quality parameter measured value is monitored number and built respectively View value.
Specifically, being monitored according to each the corresponding retransfer scheduling of prediction measured value range obtained in pretreatment stage secondary Number recommended value determines that the corresponding retransfer scheduling of each single item channel quality parameter measured value monitors number recommended value, for example, such as respectively Shown in table 2, the prediction measured value range of RSRP be [- 88 ,+∞) to monitor number recommended value be 1, SINR's for corresponding retransfer scheduling Predict measured value range be [13.5 ,+∞) to monitor number recommended value be 1, therefore, RSRP for corresponding retransfer schedulingmeasIt is corresponding It is 1, SINR that retransfer scheduling, which monitors number recommended value,measIt is 1 that corresponding retransfer scheduling, which monitors number recommended value,.
Step 620: terminal is monitored in number recommended value from all retransfer schedulings currently obtained, and it is maximum heavy to choose value It passes scheduling and monitors number recommended value as itself retransfer scheduling monitoring number.
Specifically, RSRP obtained in example as abovemeasIt is 1, SINR that corresponding retransfer scheduling, which monitors number recommended value,measIt is right It is 1 that the retransfer scheduling answered, which monitors number recommended value, therefore it is 1 that itself retransfer scheduling, which monitors number,.
In another example RSRPmeasIt is 2, SINR that corresponding retransfer scheduling, which monitors number recommended value,measCorresponding retransfer scheduling prison Listening number recommended value is 1, then chooses the maximum retransfer scheduling of value and monitor number recommended value as the monitoring time of itself retransfer scheduling It is 2 that number, i.e. itself retransfer scheduling, which monitor number,.
Therefore, terminal can be according to each single item channel quality parameter measured value currently obtained, and adjustment in real time, which retransmits, adjusts Degree monitors number, and measures poor result according to channel quality parameter and determine that final retransfer scheduling monitors number.
Further, after terminal determines that itself retransfer scheduling monitors number, terminal is monitored number according to retransfer scheduling and is set Set itself subframe into suspend mode and corresponding sleep time.
Under the prior art, in actual business transmission process, terminal is still monitored after the ACK for receiving base station feedback The purpose of retransfer scheduling is to avoid erroneous detection feedback information.According to agreement, the number for monitoring retransfer scheduling is that the number of transmissions subtracts 1, The number of transmissions is configured by base station is unified.The number of transmissions configuration is a maximum value, the number of transmissions of base station actual schedule with The variation of channel quality is likely to lower than the Configuration Values, but it is to actually occur number that retransfer scheduling, which monitors number, i.e. fixed value, The number of transmissions subtracts 1.
