Specific implementation mode
As shown in Figure 1, in one embodiment it is proposed that a kind of processing method of Timing Advance, this method can be applied
In base station, following steps are specifically included：
Step 102, the message that user equipment is sent is received, the frequency pilot sign in message is extracted.
In the present embodiment, base station receives the message that user equipment is sent, and extracts the frequency pilot sign in message.Message is general
Refer to business datum, user equipment, which can be smart mobile phone, laptop, desktop computer etc., can send the electronics of signal and set
It is standby.Specifically, base station is received by Pusch (Physical Uplink Shared Channel, Physical Uplink Shared Channel)
The uplink business data that user equipment is sent extracts the frequency pilot sign in business datum.Wherein, Pusch is used for transmitting UE (User
Equipment, user equipment) be sent to the uplink business data of base station, in business datum in a subframe include two time slots,
Include the known frequency pilot sign for carrying out channel estimation and measurement of a receiving terminal (base station) in each time slot.
Step 104, the initial value of Timing Advance is calculated according to frequency pilot sign.
In the present embodiment, base station carries out the survey of Timing Advance using the ascending pilot frequency symbol of each user equipment (UE)
Amount, and measurement result is reported to MAC layer, user equipment (UE) is handed down to by down channel after MAC layer processing, UE can be under
It is synchronous with base station to ensure that the TA values of hair carry out TA adjustment.The least unit for the Timing Advance that base station upstream physical layer measures
It is 1Ts, uplink synchronous precision is 16Ts, wherein Ts is sampling precision, and 16Ts is approximately equal to 0.52 μ s.Based on this, base station notice is used
Granularity when family equipment UE carries out TA adjustment must be the integral multiple of 16Ts.Specifically, due to the influence of environment, especially in height
In the case of interference environment, often there is deviation in the survey calculation of Timing Advance, in order to ensure the performance of uplink demodulation,
May subsequently the Timing Advance obtained to measurement be needed to be adjusted, for the ease of distinguishing, the time that will be calculated for the first time
The value of lead is known as " initial value of Timing Advance ".
Step 106, the corresponding environmental labels of user equipment are obtained, environmental labels are used to mark the environment residing for user equipment
State.
In the present embodiment, in order to obtain the ambient condition residing for current user equipment, base station obtains and the user equipment
Corresponding environmental labels, environmental labels are used to mark the ambient condition residing for user equipment.Ambient condition can be divided into two classes, and one
Kind is normal environment, and one is particular surroundings.Wherein, particular surroundings can be configured as needed, for example, by user equipment
Environment in high interference and non-high-speed is other to be all used as normal environment as particular surroundings.The weight studied in the present embodiment
Point is the case where user equipment is in particular surroundings.Specifically, the environmental labels of particular surroundings can be set as Flag=1, normally
The environmental labels of environment are set as Flag=0.So according to the environmental labels got it is known that user equipment is in anything
In the environment of sample.Wherein, the setting of environmental labels was judged the environment of user equipment according to the last time, if sentencing
The environment of disconnected user equipment is in particular surroundings, then Flag=1 will be set.Similarly, if judging at the environment of user equipment
In normal environment, Flag=0 is set.So the ambient condition residing for user equipment can be obtained according to environmental labels.
Step 108, when environmental labels indicate particular surroundings, shifted to an earlier date according to the scope and time of preset Timing Advance
The initial value of amount determines the end value of Timing Advance.
In the present embodiment, when base station get environmental labels expression be particular surroundings when, then just needing according to pre-
If the range of Timing Advance restricted adjustment, the value of the Timing Advance after adjustment are carried out to the initial value of Timing Advance
Referred to as " end value of Timing Advance ".Restricted adjustment can be by pre-setting the range of Timing Advance, that is, when being arranged
Between lead maximum value and minimum value, when the Timing Advance being calculated initial value be more than maximum value or less than minimum
When value, then the initial value of the Timing Advance is adjusted, the value of the Timing Advance is adjusted to carry in the preset time
In the range of preceding amount.In one embodiment, when the initial value of Timing Advance is more than above-mentioned maximum value, then by the maximum value
As the end value of the Timing Advance after adjustment, similarly, when the initial value of Timing Advance is less than above-mentioned minimum value, then
Using the minimum value as the end value of the Timing Advance after adjustment.Specifically, it is that ring is obtained by the physical layer of base station first
Border identifies, and when environmental labels indicate particular surroundings, still carries out restricted tune to the initial value of Timing Advance by the physical layer
It is whole, the end value of Timing Advance is obtained, the end value of the Timing Advance is subsequently reported to MAC layer, when MAC layer is according to this
Between the end value of lead decide whether to issue TA adjustment orders to user equipment, the time to ensure user equipment and base station is same
Step.In the present embodiment, when user equipment is in particular surroundings, by carrying out restricted adjustment to Timing Advance, subsequently
TA adjustment is carried out to user equipment according to the Timing Advance after the adjustment, and then can realize can be into the TA values of user equipment
Row " tune of small step ", avoid disposably adjust it is excessive, cause demodulation failure phenomena such as occur, improve uplink in high level cadre
It disturbs and the demodulation performance under non-high velocity environment.
In the present embodiment, when judging that user equipment is in particular surroundings, the value of the Timing Advance reported is carried out
Limitation adjustment, as long as being particular surroundings by the scene setting of high interference, so that it may to realize under the scene of high interference, to user
The corresponding Timing Advance of equipment carries out restricted adjustment, prevents from, because the adjustment paces of primary mistake are excessive, leading to time quantum
Receiving terminal algorithm demodulation ability is had exceeded when occurring base station side uplink after adjustment partially, avoids the occurrence of uplink demodulation failure, Yong Hushe
Situations such as standby call drop, occurs, to effectively raise demodulation performance of the uplink under high-interference environment.
As shown in Fig. 2, when environmental labels indicate particular surroundings, carried according to the scope and time of preset Timing Advance
The initial value of preceding amount determines that the step of end value of Timing Advance includes：
Step 108A, judges whether the initial value of Timing Advance is more than preset first threshold or whether is less than preset
Second threshold, if so, 108B is entered step, if it is not, then entering step 108C.
In the present embodiment, in order to carry out restricted adjustment to the value of the Timing Advance under particular surroundings, first
Judge that the initial value of above-mentioned Timing Advance whether in the range of preset Timing Advance, that is, judges the initial of Timing Advance
Whether value is more than preset first threshold or whether is less than preset second threshold, wherein when first threshold refers to preset
Between maximum value in lead range, second threshold refers to the minimum value of preset Timing Advance range, it is clear that first threshold
More than second threshold.Specifically, it is assumed that ranging from [- the 32Ts ,+32Ts] of the Timing Advance of setting, then, first threshold is
32Ts, second threshold are -32Ts.
Step 108B, when the initial value of Timing Advance is more than preset first threshold, then when being used as first threshold
Between lead end value；When the initial value of Timing Advance is less than preset second threshold, then when second threshold being used as
Between lead end value.
In the present embodiment, if the initial value of Timing Advance is more than preset first threshold, by Timing Advance
Initial value be revised as first threshold, i.e., using first threshold as the end value of Timing Advance.If Timing Advance is initial
Value be less than preset second threshold when, the initial value of Timing Advance is being revised as second threshold, i.e., using second threshold as
The end value of Timing Advance.For example, if first threshold is 32Ts, second threshold is -32Ts, if Timing Advance is initial
Value has exceeded the range of [- 32Ts ,+32Ts], more than 32Ts using 32Ts as the end value of Timing Advance, is less than -32Ts
The end value by -32Ts as Timing Advance, if in the range of [- 32Ts ,+32Ts], then it is constant, i.e., directly by when
Between lead initial value Timing Advance the most end value.
Step 108C, using the initial value of Timing Advance as the end value of Timing Advance.
In the present embodiment, if the initial value of Timing Advance more than second threshold when being less than between first threshold, i.e.,
When in the range of preset Timing Advance, the value of Timing Advance need not be adjusted, be remained unchanged, also
It is to say, directly using the initial value of Timing Advance as the end value of Timing Advance.
As shown in figure 3, in one embodiment, the processing method of above-mentioned Timing Advance further includes：
Step 110, the corresponding signal-to-noise ratio (SINR) of user equipment and noise jamming (NI) are calculated according to frequency pilot sign.
In the present embodiment, after frequency pilot sign is extracted in base station, it is also necessary to calculate user equipment according to frequency pilot sign and correspond to
Signal-to-noise ratio SINR and noise jamming NI, wherein SINR (Signal to Interference plus Noise Ratio, letter
Number with interference plus noise ratio, referred to as " signal-to-noise ratio ") refer to the signal strength received and the interference signal received (noise and is done
Disturb) intensity ratio.The value of NI (Nosie Interference, noise jamming) is for weighing noise jamming level.Wherein,
Existing calculation may be used in the calculating of SINR and NI, does not limit herein the calculation of SINR and NI.
Step 112, resource block (RB) number shared by user equipment is obtained；
In the present embodiment, RB (Resource Block, resource block), is the scheduling of resource unit in LTE, and effect is to pass
The supporting body of data is sent, is exactly used for transmission data.In uplink demodulation, if the RB numbers shared by user equipment (UE)
Fewer, then the deviation meeting bigger of TA estimations, this is because available sample point is few, corresponding estimated bias is bigger.Especially
It is under high interference scene, the RB numbers shared by user equipment are fewer, and demodulation performance declines more, it is easier to UE call drops occurs
The problems such as.
Step 114, whether user equipment is judged according to signal-to-noise ratio (Sinr), noise jamming (NI) and resource block (RB) number
In particular surroundings, if so, the corresponding environmental labels of user equipment are set as particular surroundings.
It in the present embodiment, can be with for the ease of that can judge whether user equipment is in particular surroundings rapidly next time
Using this measurement result as basis for estimation next time, for same user equipment, residing for environment in short-term
Interior is constant, it is possible to using this measurement result as basis for estimation next time.As the user that this is measured
When equipment is in particular surroundings, then the corresponding environmental labels of user equipment are set as particular surroundings, if the user equipment measured
When in normal environment, then the corresponding environmental labels of user equipment are set as normal environment.In this way, user equipment ought pass next time
When defeated business datum, directly according to environmental labels it may determine that whether user equipment is in particular surroundings, and then decide whether
Restricted adjustment is carried out to Timing Advance.Similarly, this judges whether user equipment can use in special environment
Last measurement result.
In the present embodiment, judge whether user equipment is in particular surroundings, SINR value corresponding with user equipment and NI
Value and RB numbers are related.In one embodiment, be respectively set signal-to-noise ratio, noise jamming and RB numbers thresholding, it is assumed that noise
Thresholding than SINR is set as SinrThr, and the thresholding of noise jamming NI is set as NIThr, and the thresholding of RB numbers is set as 10, then only having
The SINR measured be less than SinrThr, and, NI be more than NIThr, and RB numbers be less than or equal to 10 when, just judgement user equipment be in
" particular surroundings ", corresponding condition formula indicate as follows：
Wherein, Flag=1 indicates that particular surroundings, Flag=0 indicate normal environment.Specifically, first, it is object by base station
Reason layer calculates TA values, SINR value and RB numbers, and the value of three is then reported to MAC layer, is reported according to physical layer by MAC layer
TA values, SINR value and RB numbers judge user equipment whether be in particular surroundings, be then handed down to physical layer, be finally by object
Layer is managed to carry out the adjustment of TA values.
As shown in figure 4, in one embodiment, the processing method of above-mentioned Timing Advance further includes：
Step 116, when environmental labels indicate particular surroundings, according to the initial value of Timing Advance and preset compensation model
It encloses and determines offset corresponding with message.
In the present embodiment, when base station gets environmental labels expression particular surroundings, in addition to needing the time to estimating
The initial value of lead carries out restricted adjustment, it is also necessary to be determined to this according to the initial value of the Timing Advance estimated
The offset of message carries out TA compensation to this data packet.Usually directly using the TA values estimated as offset.But
Since the TA values estimated under particular surroundings will appear deviation, then carrying out TA benefits to this bag data according to the TA values estimated
When repaying, it is also desirable to carry out restricted adjustment to offset.Shape of the restricted adjustment using setting compensation range is carried out to offset
Formula is carried by judging whether the TA values that estimate in the compensation range of the setting are adjusted offset according to the time
The initial value of preceding amount and preset compensation range determine offset corresponding with above-mentioned message.Specifically, compensation range is set
Maximum value and minimum value make the maximum value if the TA values (i.e. the initial value of Timing Advance) estimated are more than maximum value
For determining offset, if the TA values estimated are less than minimum value, using minimum value as the offset of determination, when what is estimated
When TA values are between minimum value and maximum range, then directly using the TA values estimated as offset.In one embodiment,
It can set compensation range to [- 32Ts ,+32Ts], the TA values even compensated have exceeded the range of [- 32Ts ,+32Ts],
More than 32Ts, corresponding offset is adjusted to 32Ts, and less than -32Ts, corresponding offset is set as -32Ts, if
It is in the range of [- 32Ts ,+32Ts], then constant, i.e., it is compensated according to measured value.
Step 117, corresponding compensation is carried out to message according to determining offset to demodulate.
In the present embodiment, the adjustment of Timing Advance be for the ease of being demodulated to receiving message next time, and
The determination of offset is in order to which the message (business datum) received to this compensates demodulation.Due to estimating in particular circumstances
The TA values of meter may be bigger than normal, so needing first to determine the compensation used when the business datum for receiving this demodulates
Value, then compensates the business datum received originally according to determining offset, and then to the business number after compensation
According to being demodulated.
In the present embodiment, the TA value deviations estimated under high interference in order to prevent are excessive, more by this compensation data
Partially, this demodulation is influenced, is also required to carry out restricted adjustment to offset here.It generally can will be to the limitation of offset and right
The adjustment mode of Timing Advance is consistent, that is, compensates for n Ts, just also reports n Ts, while subsequently allowing user equipment (UE)
Also adjust n Ts, be conducive in this way wave cherish in can TA process flows be in a stable state, not because bursty interference is led
The mistake of cause makes entire TA process flows disorderly fall.
In one embodiment, when environmental labels expression particular surroundings, according to the range of preset Timing Advance
Further include after the step of determining the end value of Timing Advance with the initial value of Timing Advance：Most according to Timing Advance

Restricted adjustment is carried out to Timing Advance, the end value of Timing Advance is obtained, is needed later by the Timing Advance most
Final value is reported to MAC layer, and MAC layer decides whether to issue TA adjustment orders according to the end value of the Timing Advance.Specifically, by
The MAC layer of base station judges whether the end value of Timing Advance has exceeded preset thresholding, if so, issuing TA to user equipment
Adjust instruction, to ensure the time synchronization of UE and base station.In the present embodiment, by time advance in the environment of high interference
