Description
Technical field
The present invention relates to the communications field, more particularly to a kind of method and device of the terminal scheduling of DRX states.
Background technology
It is discontinuous in Long Term Evolution (Long Term Evolution, LTE) system of 3-G (Generation Three mobile communication system)
The application of (Discontinuous Reception, the DRX) technology of reception can optimize terminal system resource by timing wake-up
Configuration, power is saved, and reach the effect of power saving, so as to extend the stand-by time of terminal.
In the prior art, the DRX function controls in LTE system are physically located at the media access control (Medium of protocol stack
Access Control, MAC) layer, its major function is that control sends instruction to physical layer, and notice physical layer is in the specific time
Monitor Physical Downlink Control Channel (Physical Downlink Control Channel, PDCCH).
Specifically, if terminal radio resource control connect (Radio Resource Control Connected,
RRC_CONNECTED) state, terminal use DRX working specification, discontinuously monitor PDCCH, DRX realization mechanisms are using a variety of
Timer coordinates running to ensure the reception of downlink data and uplink authorization, and the timer related to DRX mainly has：Duration
Timer (On-Duration Timer), the static timers of DRX (DRX-Inactivity Timer), DRX retransmission timers
(DRX-Retransmission Timer), contention resolved timer (MAC-Contention Resolution Timer), four
Reception antenna monitoring PDCCH will be opened during kind timer operation, remaining time will not open reception antenna, in sleep shape
State.
In the case of normal operation, base station can keep with terminal identical DRX working methods, and in real time understand terminal be to be in
Activated state or sleep state, therefore ensure to transmit data in activator appliance, it will not carry out data transmission in sleep period.
But in LTE system, base station often detects the dispatch request of false-alarm, i.e., terminal be in inactive state and
Data need not be sent, the mistaken verdict of signal arriving is but made in base station.In the prior art, physically line link control is believed
The dispatch request carried on road (Physical Uplink Control Channel, PUCCH) allows have a certain proportion of void
It is alert, it is, base station when detecting the dispatch request of false-alarm, may proceed to perform according to the DRX flows of protocol requirement, but due to
Terminal is practically without sending real dispatch request, so DRX-Inactivity Timer will not be started, so, base station and
Terminal will have that DRX states are inconsistent, may result in the decoding result of the up-downgoing data of base station scheduling and be all
, there is up-downgoing data transmission fault in NACK, i.e., non-response.Specifically, base station can perform following operation：
Alternate medial center (Alternate Media Center, AMC) think terminal eat dishes without rice or wine channel condition variation, then can
Modulation and coding strategy (Modulation and Coding Scheme, MCS) grade of scheduling are lowered, reduces single and effectively adjusts
Handling capacity when spending, it can so cause terminal when activated state sends data, a Signaling Radio Bearer (Signaling
Radio Bearer, SRB) signaling bag needs sliced transmission, and overall time delay is increased, causes the communication barrier；
Base station think terminal eat dishes without rice or wine channel condition variation, can be based on the power headroom reporting (PHR) preserved when matching last time
Power control information such as (Power Headroom Report, PHR), up-regulation TPC command word is sent to terminal, to raise this time as eventually
The power resource of distribution is held, so, causes terminal and base station at the time of can just match, the TPC that will necessarily be raised according to base station
Command word and update power parameter, that is, raise transmission power, if terminal does not send data and be again introduced into DRX states, just can not
The TPC command word of downward is received, and if repeating said process, terminal can be caused to only receive up-regulation TPC command word always, caused
Terminal can use the big transmission power after continuous up-regulation when activated state sends data, so as to other users in cell or
The user of other cells interferes.

Embodiment
The embodiment of the present invention devises a kind of method and device of the terminal scheduling of DRX states, is judged by uplink scheduling
Whether the dispatch request received during DRX sleep states is false-alarm, so as to change the DRX states of base station side record terminal, and it is right
It should correct in AMC and be adjusted on the strategy with closed-loop power control, solve base station due to detecting that the dispatch request of false-alarm causes
Base station and terminal the problem of state is inconsistent under DRX scenes, avoid because base station and the SOT state of termination it is inconsistent and caused by extend
Signaling transmission time and undue the drawbacks of improving terminal transmission power, so as to ensure that the optimum performance of air interface.
The preferred embodiment of the present invention is described in detail with reference to Figure of description.
As shown in fig.1, in the embodiment of the present invention, when realizing terminal scheduling under DRX scenes, base station performs following behaviour
Make：
Step 100：Base station receives dispatch request, and by the signal to noise ratio of the dispatch request of acquisition and default first threshold value
It is compared with the second threshold value, obtains comparative result, wherein, the first threshold value is higher than the second threshold value.
In the embodiment of the present invention, the dispatch request that base station receives is probably that terminal under DRX scenes is truly sent
Dispatch request, it is also possible to the false-alarm that base station itself detects.
In the embodiment of the present invention, the first threshold value is referred to as high threshold, and the second threshold value is referred to as low threshold,
According to high threshold and low threshold, whether the dispatch request that base station can determine to receive is false-alarm.The value of high threshold and low threshold
It is configured based on experience value, optimization can be updated at any time.
Specifically, in actual implementation process, if the signal to noise ratio for the dispatch request that base station obtains is higher than default high threshold
(e.g., high threshold is arranged to 10db), then base station judge this receive dispatch request it is authentic and valid, then, base station can by this
The DRX states of the terminal of ground record are converted to activated state by sleep state, also, base station is carried out according to dispatch request to terminal
PUCCH closed-loop power controls, base station is according to Physical Uplink Shared Channel (Physical Uplink Shared Channel, PUSCH)
Power information carries out PUSCH closed-loop power controls to terminal；
If the signal to noise ratio for the dispatch request that base station obtains is less than default low threshold (e.g., threshold ones are arranged to -10db),
Then base station judges that this dispatch request received is false-alarm, then, base station can continue the DRX states of the terminal of local record
Sleep state is maintained, and without closed-loop power control.
And for base station obtain dispatch request signal to noise ratio between two thresholdings, i.e., less than default high threshold and height
In the situation of default low threshold, base station will further process, and this point will make introduction in subsequent embodiment.
Step 110：Base station determines that the signal to noise ratio of dispatch request is less than the first threshold value and height according to the comparative result of acquisition
When the second threshold value, basic MCS etc. is set for the above-mentioned terminal in DRX states according to the AMC information that last time preserves
Level, and PUSCH signals are sent according to basic MCS grades dispatch terminal.
Specifically, the AMC information that base station can preserve according to last time, optionally, terminal last time can be combined
Channel quality instruction (Channel Quality Indication, CQI) information of feedback, it is determined that corresponding target MCS grades,
Target MCS grades are reduced into N number of grade again, obtain basic MCS grades, wherein, N is parameter preset, e.g., N=2 or 3, and so,
When being scheduled according to basic MCS grades to terminal, it is ensured that terminal also can in the case where channel condition of eating dishes without rice or wine is worst
It is enough to send PUSCH signals to base station.
Step 120：Base station judges whether to receive the PUSCH signals that terminal is truly sent, if so, then by local record
The DRX states of terminal are converted to activated state by sleep state, otherwise, it determines dispatch request is false-alarm, and by the terminal of local record
DRX states continue to sleep state.
Because network environment is complicated, interference noise everywhere be present, therefore, no matter whether terminal truly have sent PUSCH letters
Number, base station can all receive PUSCH signals, and therefore, whether the PUSCH signals that base station needs to judge to receive are that terminal is truly sent out
The signal sent.
Specific method is：Base station receives PUSCH signals, wherein, signal to noise ratio, absolute power are included in PUSCH signals and is translated
Code three kinds of status informations of result, base station selection one of which status information compared with predetermined threshold value, or, base station selection
The combination of any several status informations records comparative result compared with each self-corresponding predetermined threshold value.
If all parameters reach corresponding predetermined threshold value, base station judges that this PUSCH signal received is eventually
What end was truly sent, represent that terminal is in activated state, then base station is turned the DRX states of the terminal of local record by sleep state
It is changed to activated state.
Further, base station complete false-alarm judge after, it is necessary to according to the basic MCS grades of acquisition to AMC information carry out
Amendment, use during to be scheduled next time, but because basic MCS grades can not truly reflect the letter of eating dishes without rice or wine of present terminal
Road condition, therefore, it is necessary to optimized to basic MCS grades, optionally, in the embodiment of the present invention, basic MCS grades are multiplied by
One weighted factor (e.g., MCS*1.5), so, basic MCS grades can be reduced to dispatching caused passive shadow next time
Ring.
Also, base station also needs to carry out closed-loop power control to terminal, specifically, base station is carried out according to dispatch request to terminal
PUCCH closed-loop power controls, base station carry out PUSCH closed-loop power controls according to PUSCH power informations to terminal.
If any one parameter not up to corresponding to predetermined threshold value, base station judges PUSCH signals that this is received simultaneously
Nonterminal is truly sent, and it is false-alarm to show this dispatch request, wherein, why base station so judges, be because, base station pin
N number of MCS grades are reduced to terminal, there is provided basic MCS grades, have ensured eating dishes without rice or wine also in the case that channel condition is worst
The PUSCH signals that terminal is truly sent are received, if the PUSCH signals this time received are still not up to predetermined threshold value, table
Bright and nonterminal is truly sent, i.e., this dispatch request is false-alarm, then base station continues to the DRX states for locally recording terminal
Sleep state, and without AMC Information revisions and closed-loop power control.
The embodiment of the present invention is described in further detail with reference to specific application scenarios, idiographic flow is refering to figure
Shown in 2：
Step 200：Under DRX scenes, base station sets two thresholdings for the signal to noise ratio in the expected dispatch request received,
High threshold and low threshold.
Wherein, high threshold and the value of low threshold are rule of thumb set, and can be updated optimization at any time, place
After receiving dispatch request in the base station of sleep state, whether the dispatch request that can be received according to the judgement of default two thresholdings is true
It is real effective.
Step 210：Base station by the signal to noise ratio of the dispatch request received compared with default high threshold and low threshold,
Obtain comparative result.
Wherein, if the signal to noise ratio in the dispatch request that base station judges to receive is higher than default high threshold, step is carried out
211；
If the signal to noise ratio in the dispatch request that base station judges to receive is less than default low threshold, step 212 is carried out；
If the signal to noise ratio in the dispatch request that base station judges to receive is between default two thresholding, and less than high threshold,
Higher than low threshold, then step 220 is carried out.
Step 211：Base station judges that this dispatch request is authentic and valid, will locally record the DRX states of terminal by sleep state
Activated state is converted to, and participates in closed-loop power control.
Specifically, base station carries out PUCCH closed-loop power controls according to dispatch request to terminal, and base station is according to PUSCH power informations
PUSCH closed-loop power controls are carried out to terminal.
Step 212：Base station judges that this dispatch request is invalid, is false-alarm, and the DRX states for locally recording terminal are continued to tie up
Sleep state is held, and is not involved in closed-loop power control.
So, base station is avoided after the dispatch request of false-alarm is received, and still carries out closed-loop power control for error message.
Step 220：Base station less than high threshold and is higher than the situation of low threshold for the signal to noise ratio of dispatch request, according to last
The AMC information once preserved, basic MCS grades, and tentative scheduling PUSCH are pre-set for terminal.
Specifically, the AMC information for the terminal that base station preserves according to last time, or combine last time terminal feedback
CQI information, the target MCS grades of channel condition it is determined that sign last time terminal is eated dishes without rice or wine, then on the basis of target MCS grades
N number of grade is reduced, obtains basic MCS grades.Wherein, N is parameter preset, for example, N=2 or 3.
So, the physical transmission rate according to corresponding to basic MCS grades, ensure that terminal is worst in channel condition of eating dishes without rice or wine
In the case of, also PUSCH signals can be sent to base station, can avoid leading to not normally send out because terminal eats dishes without rice or wine bad channel conditions
The problem of sending PUSCH signals.
Step 230：Base station judges whether to receive the PUSCH signals that terminal is truly sent, if so, step 240 is then carried out,
Otherwise, step 212 is carried out.
Specifically, the physical transmission rate according to corresponding to basic MCS grades, after the tentative scheduling PUSCH in base station, base station can
Whether terminal is truly sent for this is received according to the Quality estimation of the PUSCH signals received PUSCH signals.
Specific method is：Base station is by the signal to noise ratio in the PUSCH signals received, absolute power and decodes appointing in result
Anticipate a kind of compared with respective default threshold value, if reaching threshold value, carry out step 240；Otherwise, step 212 is carried out.
Or
Base station is by the signal to noise ratio in the PUSCH signals received, absolute power and decodes any several group in result
Close respectively compared with respective default threshold value, if all reaching threshold value, carry out step 240；Otherwise, step is carried out
212。
Step 240：Base station judges that this PUSCH signal received is that terminal is truly sent, and will locally record terminal
DRX states activated state is converted to by sleep state.
Specifically, if base station judges that this PUSCH signal received is that terminal is truly sent, now terminal is shown
Being in activated state, then base station needs to locally record corresponding to the DRX states of terminal is converted to activated state by sleep state, so as to
Follow-up control is carried out to terminal.
Step 250：Base station is modified according to the basic MCS grades of acquisition to AMC information, and according to dispatch request to end
End carries out PUCCH closed-loop power controls, and carries out PUSCH closed-loop power controls to terminal according to PUSCH power informations.
Wherein, when base station is modified according to the MCS grades of acquisition to AMC information, because basic MCS grades are to attempt
Property scheduling PUSCH when set, it is therefore an objective to ensure that terminal can also send PUSCH letters when channel condition of eating dishes without rice or wine is worst to base station
Number, but the basic MCS grades can not truly reflect the channel condition of eating dishes without rice or wine of present terminal, therefore, base station is needed to basis
MCS grades optimize, and the specific method of optimization is：Basic MCS grades are multiplied by a weighted factor (e.g., MCS*1.5).
So, basic MCS grades can be reduced to dispatching caused negative influence next time, and avoid base station and exist
After the dispatch request for receiving false-alarm, still closed-loop power control is carried out for error message.
Based on above-described embodiment, as shown in fig.3, in the embodiment of the present invention, under DRX scenes, base station includes relatively more single
Member 300, setting unit 310 and judging unit 320.
Comparing unit 300, for receiving dispatch request, and by the signal to noise ratio of dispatch request and default first threshold value and
Second threshold value is compared, and obtains comparative result, wherein, the first threshold value is higher than the second threshold value；
Setting unit 310, for the comparative result according to acquisition, determine that the signal to noise ratio of dispatch request is less than the first threshold value
And when being higher than the second threshold value, basic MCS etc. is set for terminal according to the alternate medial center AMC information that last time preserves
Level；
Judging unit 320, the PUSCH signals truly sent for judging whether to receive terminal, if so, then by local note
The DRX states of the terminal of record are converted to activated state by sleep state, otherwise, it determines dispatch request is false-alarm, and by local record
The DRX states of terminal continue to sleep state.
So, under DRX scenes, whether the dispatch request that base station can determine whether to receive is false-alarm, solve because of base station and
Caused by the SOT state of termination is inconsistent the problem of up-downgoing data transmission fault, avoid mistake scheduling and caused by itself communicate
Obstacle and the interference to other users.
It is preferred that if the present apparatus according to comparative result, determines that the signal to noise ratio of dispatch request is higher than default first threshold value,
Then the present apparatus judges that the dispatch request that this is received is authentic and valid, and the DRX states for locally recording terminal are changed by sleep state
