Description
Technical field
The present invention relates to the processing method of wake-up in advance and dress of communication technical field, more particularly to a kind of discontinuous reception
Put.
Background technology
In order to extend user equipment (User Equipment, UE) stand-by time, Long Term Evolution (English as much as possible
Text：Long Term Evolution, referred to as：LTE) related protocol (36.321,36.304 etc.) introduces discontinuous reception (English
Text：Discontinuous Reception, referred to as：DRX) mechanism.The basic thought of the mechanism is：When UE is in holding state
When, base station equipment (English：Evolved Node B, referred to as：ENB) beep-page message can be sent to UE at interval of some cycles
(Paging), UE only needs to monitor whether there is business arrival in specific calling time point, and in the beep-page message moment twice
Between, in order to save power consumption, UE can close most of circuit and enter sleep state.A discontinuous receiving cycle as shown in Figure 1
Schematic diagram, from figure 1 it appears that whole DRX cycle can be divided into three parts：It is formal to wake up duration, sleep duration and carry
Preceding wake-up duration.
Wherein, formally wake up duration depend primarily on eNB scheduling, and wake up in advance duration depending on UE specific implementation,
It can be properly received and seek in general, awakening phase needs to complete frequency-tracking and timing tracking in advance, during formally to wake up
Exhale (English：Paging) indicate, in addition, in order to maintain the functions such as the normal gravity treatment switchings of UE, also need to perform cell searching and energy
Measurement.If it will be apparent that length when waking up in advance, for sleep duration with regard to longer, UE power consumptions also can be lower.
Precoding vectors signal (English：Precoding Vector Signal, referred to as：PVS it is) that a kind of eNB sides master is same
Walk signal (English：Primary Synchronization Signal, referred to as：PSS)/auxiliary synchronous signals (English：
Secondary Synchronization Signal, referred to as：SSS) sending strategy, some base station equipment manufacturers can send
During PSS/SSS signals in this way.So that eNB has two antenna ports as an example, its specific practice is to send PSS/SSS
When, flowed through using 5ms as cycle wheel and go through [1,1], [1, -1], [1, j], [1,-j] these precoding vectors are to PSS/SSS progress
Precoding.Advantage of this is that being said from the angle of whole system, all UE of whole cell can be allowed to obtain to a certain extent
Obtain preferable signal noise ratio (English：Signal to Noise Ratio, referred to as：SNR), be not in the cell SNR mono- that has
It is straight very high, and situation very low always some cell SNR occurs.But reaching for this effect must have an important prerequisite, that
It is exactly that UE will can be to upper all possible precoding vectors.If UE does not do appropriate optimization in scheduling, it is most likely that occurs every
The situation that secondary PSS/SSS can not be parsed occurs.Such as in the direct-connected environment in laboratory, if every time search it is just right during cell searching
Upper [1, -1], then the signal of two antenna ports will be completely counterbalanced by when UE is received, and cause can not to solve every time pair, so as to cell
Search for entirely ineffective.
In awakening phase in advance, there is the multinomial work such as Time and Frequency Synchronization, cell searching, energy measurement to do, if scheduling is not
Appropriately, it is likely that produce a large amount of unnecessary power consumptions.
Therefore, it is necessary to efficiently complete to shift to an earlier date the operation in awakening phase in subframe in as few as possible waking up in advance.

Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other under the premise of creative work is not made
Embodiment, belong to the scope of protection of the invention.
Referring to Fig. 2, the flow for waking up processing method in advance for a kind of discontinuous reception provided in an embodiment of the present invention
Schematic diagram, this method comprise the following steps：
Step S101, selected in current discontinuous reception DRX subframe and carry out current area search and/or Time and Frequency Synchronization
The essential subframe waken up in advance.
It is main to consider to need to complete in awakening phase in advance when selecting the subframe waken up in advance in current DRX subframe
Operation needed for the subframe that takes, these operations include cell searching, Time and Frequency Synchronization, energy measurement etc., but are not each shift to an earlier date
These operations must be all included in awakening phase, for example, this DRX need not start cell searching when waking up, then can be omitted
Cell search procedure, do not select the subframe carried out needed for cell searching.
But when selecting the subframe of these operations, still there is an order, due to needing to consider PVS problems, it is necessary to elder generation
Selecting for cell searching subframe is carried out, then on the basis of the subframe for the progress cell searching picked out, when selecting progress
The synchronous subframe of frequency, if the subframe for the progress cell searching picked out can meet to carry out wanting for subframe needed for Time and Frequency Synchronization
Ask, then can carry out Time and Frequency Synchronization simultaneously in the subframe for carrying out cell searching, to take wake-up subframe in advance as few as possible
Efficiently complete to shift to an earlier date the operation in awakening phase, save UE power consumption.The cell searching and Time and Frequency Synchronization picked out are (if all
In the presence of if) subframe be the essential subframe waken up in advance.
When selecting the subframe for carrying out cell searching, in order to solve the problems, such as PVS, carrying out the subframe of cell searching needs to hand over
Misadjustment degree, i.e., when the subframe of secondary cell searching and next cell searching staggers, so may insure will not asking due to PVS
Topic causes UE always to search less than cell.
Step S102, based on the essential subframe picked out, carry out energy measurement is selected in the subframe of the DRX
The alternative subframe waken up in advance, wherein, the alternative subframe is a part for the essential subframe, or including the essential son
At least one subframe not being selected in the whole of frame and the subframe of the DRX.
It is a step after essential subframe is selected to carry out selecting for the subframe of energy measurement, standby for what is waken up in advance
Select selecting for subframe.If the essential subframe selected and consider to have picked out of alternative subframe can meet to carry out energy measurement behaviour
The requirement of subframe needed for work, energy measurement just is carried out in the subframe for carrying out cell searching and/or Time and Frequency Synchronization, if can not expire
Foot is required, then the subframe part that can not meet requirement is further selected in the DRX subframe not being selected.
Step S103, subframe cutting is carried out to the alternative subframe picked out, removes the redundancy for meeting to impose a condition
Subframe.
When being selected due to carrying out alternative subframe, lack overall consideration, some redundant sub-frames may be produced, it is therefore desirable to right
The alternative subframe picked out carries out subframe cutting, removes the redundant sub-frame for meeting to impose a condition, as few as possible to ensure to take
The subframe that wakes up in advance efficiently complete operation in advance in awakening phase, save UE power consumption.
Step S104, in the essential subframe picked out and perform in remaining alternative subframe after subframe cutting
Wake operation in advance.
Carry out the essential subframe of cell searching and/or Time and Frequency Synchronization and carry out the alternative subframe scheduling of energy measurement
After complete, and after having been cut to alternative subframe, cell searching and/or Time and Frequency Synchronization operation are performed in essential subframe,
After the essential subframe picked out and progress subframe cutting energy measurement operation is performed in remaining alternative subframe.
The wake-up processing method in advance of a kind of discontinuous reception provided according to embodiments of the present invention, by successively current
The essential subframe waken up in advance for carrying out current area search and/or Time and Frequency Synchronization is picked out in the subframe of discontinuous reception, so
Afterwards based on the essential subframe picked out, it is alternative that waking up in advance for progress energy measurement is selected in the subframe of discontinuous reception
Subframe, and the alternative subframe to picking out carries out subframe cutting, it is ensured that with the subframe of wake-up in advance as few as possible efficiently
Complete to shift to an earlier date the operation in awakening phase.
Referring to Fig. 3, the stream for waking up processing method in advance for another discontinuous reception provided in an embodiment of the present invention
Journey schematic diagram, this method comprise the following steps：
Step S201, selected in current discontinuous reception DRX subframe and carry out waking up in advance for current area search
Essential subframe.
Selecting for the essential subframe waken up in advance of cell searching is carried out, considers both of which：
The first situation：FDD (English：Frequency Division Duplex, referred to as：FDD) pattern
In order to solve the problems, such as PVS, cell searching needs staggeredly to dispatch, cell under mode of frequency division duplexing as shown in Figure 4
Search subframe selects schematic diagram, for example, when the 5ms of time cell searching and next cell searching is to hand in DRX 10ms subframes
(this accounts for preceding 5ms, then accounts for rear 5ms next times) staggered.So can ensure that will not be because PVS presence causes UE to be likely to eternal
Also search less than cell.
Second of situation：Time division duplex (English：Time Division Duplex, referred to as：TDD) pattern
Because TDD is synchronization system, PSS/SSS signals only fall in subframe 0 and subframe 5, now only need to wake up 0/5.
A kind of cell searching subframe under tdd mode as shown in Figure 5 selects schematic diagram, which show under tdd mode just
Formula wakes up the situation that subframe is 0.
Another cell searching subframe under tdd mode as shown in Figure 6 selects schematic diagram, and which show under tdd mode
It is formal wake up subframe it is non-zero and 5 situation.
Step S202, according to upper DRX channel quality, it is determined that carrying out the number of sub frames of Time and Frequency Synchronization in current DRX.
Step S203, if the number of the essential subframe of the progress cell searching picked out meets to carry out Time and Frequency Synchronization
Number of sub frames, then without additionally select carry out Time and Frequency Synchronization essential subframe.
After establishing cell searching and needing the subframe that wakes up in advance, Time and Frequency Synchronization (timing tracking and frequency are next determined
Tracking) stage needs the subframe selected.
Each DRX, which shifts to an earlier date awakening phase, needs how many individual subframes to be used for Time and Frequency Synchronization according to upper DRX channel quality shapes
Condition determines.During specific implementation, there can be the parameter of a variety of reflection channel qualities available, such as SNR, peak-to-average force ratio (English：
Peak-Average Ratio, referred to as：PAR) etc., illustrated here by taking PAR as an example.
● if the PAR that last DRX is obtained is higher than Thres1 but is less than Thres2, and next DRX Time and Frequency Synchronizations only need to account for
With two descending sub frames.
● if the PAR that last DRX is obtained is higher than Thres2, and next DRX Time and Frequency Synchronizations only need to take 1 descending son
Frame.
● if the PAR that last DRX is obtained is less than Thres1, and next DRX Time and Frequency Synchronizations need to wake up 4 descending sub frames.
The schematic diagram of comprising filtering operation the DRX cycle shown in Fig. 7 is referred to, current DRX obtains a PAR,
Then the value can be obtained F_PAR with history filtering value filtering, filtering mode is filtered using Alpha, i.e., using formula (1)：
F_PAR (n+1)=PAR (n+1) * Alpha+ (1-Alpha) * F_PAR (n) ... formula (1)
Alpha acquiescences selection 1/4.
After the number of sub frames that Time and Frequency Synchronization needs wake up is established, enter one on the basis of cell search phase has selected subframe
The descending sub frame number that step selection needs additionally to wake up (if this DRX need not start cell searching when waking up, omits cell
Search step, directly select Time and Frequency Synchronization subframe), specifically chosen mode is：
Pushed away forward from the formal subframe that wakes up, until required descending sub frame number is satisfied.If cell search phase has been called out
Descending sub frame number of waking up can meet Time and Frequency Synchronization demand, then without additionally waking up.Illustrated below for different scenes (under
Multicast broadcast multimedia service (English is not accounted in the example in face：Multimedia Broadcast Multicast
Service, referred to as：MBMS) the configuration of subframe, that is, assume there is no MBMS subframes)：
The subframe of wake-up in advance of cell searching and Time and Frequency Synchronization under fdd mode as shown in Figure 8 selects schematic diagram, it is assumed that
This DRX Time and Frequency Synchronization needs to wake up 4 subframes in advance, as seen from Figure 8, because cell search phase has waken up number of sub frames in advance
More than 4, therefore even if after considering Time and Frequency Synchronization, subframe is waken up without extra again.
The subframe of wake-up in advance of cell searching and Time and Frequency Synchronization under tdd mode as shown in Figure 9 selects schematic diagram, it is assumed that
This DRX Time and Frequency Synchronization needs to wake up 2 subframes in advance, and it is descending son that TDD sub-frame formats, which are configured to now only subframe 0/5,
Frame, as seen from Figure 9, when only considering cell searching, current DRX is without additionally waking up, but after considering Time and Frequency Synchronization, need in advance several two
Individual descending sub frame is waken up.
Step S204, calculated backward from first essential subframe, if the essential subframe number meet synchronize it is small
The subframe demand number of the energy measurement in area, then the alternative subframe for the energy measurement for synchronizing cell need not be additionally selected, it is no
Then, at least one subframe is additionally selected from the subframe not being selected of the DRX, until the energy for meeting to synchronize cell
The demand number of the alternative subframe of measurement.
Step S205, if the essential subframe selected and synchronize cell energy measurement alternative subframe number it
The subframe demand number of the energy measurement of asynchronous cell is carried out with satisfaction, then carries out measuring for asynchronous cell without additionally select
The alternative subframe of amount, otherwise, selected by the timing position of each asynchronous cell from the subframe not being selected of the DRX corresponding
Alternative subframe.
Step S206, the alternative subframe of the energy measurement for the progress asynchronous cell picked out is mapped to what is picked out
On the position of the alternative subframe of synchronized cells.
After essential subframe has been selected (cell searching and Time and Frequency Synchronization), restart the selection (energy measurement) of alternative subframe.
Alternative selecting for subframe is carried out in two stages：
● synchronized cells subframe is selected
● asynchronous cell subframe is selected
Synchronized cells subframe picking rule：
● from first essential subframe to pusher, if essential subframe meet demand, no longer wakes up other subframes；
If ● essential subframe still can not meet demand, other available subframes are additionally selected, until the demand of synchronized cells
It is satisfied；
Asynchronous cell subframe picking rule：
If ● the measurement demand of asynchronous cell can be met by having selected subframe (essential+alternative), no longer select other subframes；
● if the measurement demand of asynchronous cell can not be met, corresponding son is selected by the timing position of each asynchronous cell
Frame；
● the wake-up subframe of asynchronous cell will be finally mapped to onto the position subframe of synchronized cells (if some asynchronous subframe
Among two synchronous subframes, then the two synchronous subframes are required for being selected)；
In the energy measurement stage, no matter synchronized cells or asynchronous cell, specifically select how many individual subframes depend on it is specific
Two dimensions realized：
1, single subdistrict is in order to meet number of sub frames needed for measurement accuracy under different bandwidth；In general, bandwidth is smaller, it is required
Number of sub frames is about more, and bandwidth is bigger, and required number of sub frames is fewer；
2, UE the multiple cells of synchronization parallel processing ability；In general, bandwidth is smaller, (caching and amount of calculation are got over
It is small), parallel ability is stronger；Bandwidth is bigger, and required number of sub frames is more；
Referring to Fig. 10, selecting schematic diagram completely to wake up subframe in advance, we illustrate by taking 5M Measurement bandwidths as an example
The picking rule of alternative subframe, it is assumed that the cell of each 5M bandwidth needs 4 subframes to survey standard, and UE can handle parallel it is 4 small
Area, it is assumed that now have 6 synchronized cells, 2 asynchronous cells, accompanying drawings are as follows：
It can be seen that when only considering synchronized cells, 3 alternative subframes are additionally picked after essential subframe, are being considered
During asynchronous cell, now subframe 9,0,1, the 2 also extra disposal ability with 2 cells, therefore the processing of asynchronous cell can be positioned over
This, but consider the subframe head of itself and synchronized cells and do not line up, the subframe 2 of asynchronous cell has actually occupied synchronized cells
Subframe 3, wake up duration based on synchronized cells due to final to count, therefore the subframe 3 of final synchronized cells must also obtain
To wake up.
What deserves to be explained is the number of the synchronized cells or asynchronous cell if necessary to progress energy measurement is more, can
The energy measurement of synchronized cells or asynchronous cell can not be fully finished by distributing to main plot and carrying out the subframe of wake operation in advance
Operation, then in this case, the remaining operations of energy measurement can also be carried out in formal awakening phase.
Step S207, subframe cutting is carried out to the alternative subframe picked out, removes the redundancy for meeting to impose a condition
Subframe.
Step S208, in the essential subframe picked out and perform in remaining alternative subframe after subframe cutting
Wake operation in advance.
When essential subframe+alternative subframe all after the completion of, enter subframe and cut the stage, when why having a step because by
After aforesaid way progress subframe is selected, some redundant sub-frames may be produced (because synchronized cells and asynchronous cell are chosen by cell
Choosing, lack overall consideration).Cut and carried out only for alternative subframe, it is elapsed forward from the formal subframe that wakes up, and is investigated one by one alternative
Subframe (circulation is carried out)：
● if essential subframe can meet that the measurement demand of synchronized cells or present sub-frame cannot be used for synchronized cells measurement；
● if essential subframe can meet that the measurement demand of asynchronous cell or present sub-frame cannot be used for asynchronous cell measurement.
When the two conditions are all satisfied, the subframe is no longer selected (being removed), otherwise becomes the alternative subframe
For essential subframe；
After above step, each DRX subframe in advance wakes up number and is determined that the number of sub frames finally waken up is must
Select subframe；
Step S209, according to the channel quality of a upper DRX, it is determined that receiving the number for performing the wake operation in advance
According to the number for the radio-frequency channel that need to start.
Step S210, however, it is determined that the number for carrying out receiving the radio-frequency channel of data is one, in a base band will be in institute
State the data received in a radio-frequency channel to be replicated, data and the data of duplication in the base band to receiving
Handled.
After subframe selects end, it is to use that can determine that this DRX shifts to an earlier date awakening phase according to last DRX signal quality
Single radio frequency channel reception data still receive data using two or more radio-frequency channels, that is, use single receipts or double receipts, together
Sample, the parameter of channel quality is now reacted using SNR, PAR etc., is illustrated here by taking SNR as an example, if last DRX is obtained
The SNR arrived is more than certain thresholding (such as 15dB), then this DRX, which shifts to an earlier date awakening phase, can use single receipts, otherwise be received with double.
It is determined that in the case of using single receive, can two ways it is optional：
1st, radio-frequency channel corresponding to a receipts is only opened, base band is also handled using only single channel；
2nd, radio-frequency channel corresponding to a receipts is only opened, base band is a by the data duplication of radio-frequency channel, docks in a base band
The data received and the data replicated are handled.
Because LTE gives tacit consent to UE at least two reception antennas, base band is also designed by two paths, now according to mode 2 often
Radio-frequency power consumption can be saved, can inherit that base band is existing to realize structure again.

It is main to consider to need to complete in awakening phase in advance when selecting the subframe waken up in advance in current DRX subframe
Operation needed for the subframe that takes, these operations include cell searching, Time and Frequency Synchronization, energy measurement etc., but are not each shift to an earlier date
These operations must be all included in awakening phase, for example, this DRX need not start cell searching when waking up, then can be omitted
Cell searching, do not select the subframe carried out needed for cell searching.
But when selecting the subframe of these operations, still there is an order, due to needing to consider PVS problems, it is necessary to elder generation
Selecting for cell searching subframe is carried out, then on the basis of the subframe for the progress cell searching picked out, when selecting progress
The synchronous subframe of frequency, if the subframe for the progress cell searching picked out can meet to carry out wanting for subframe needed for Time and Frequency Synchronization
Ask, then can carry out Time and Frequency Synchronization simultaneously in the subframe for carrying out cell searching, to take wake-up subframe in advance as few as possible
Efficiently complete to shift to an earlier date the operation in awakening phase, save UE power consumption.The cell searching and Time and Frequency Synchronization picked out are (if all
In the presence of if) subframe be the essential subframe waken up in advance.
When selecting the subframe for carrying out cell searching, in order to solve the problems, such as PVS, carrying out the subframe of cell searching needs to hand over
Misadjustment degree, i.e., when the subframe of secondary cell searching and next cell searching staggers, so may insure will not asking due to PVS
Topic causes UE always to search less than cell.
Second subframe module of selection 12, for based on the essential subframe picked out, being chosen in the subframe of the DRX
Choosing carries out the alternative subframe waken up in advance of energy measurement, wherein, the alternative subframe is a part for the essential subframe, or
Whole including the essential subframe and at least one subframe not being selected in the subframe of the DRX.
The subframe for carrying out energy measurement is selected after essential subframe is selected, for the alternative subframe that is waken up in advance
Select.If the essential subframe selected and consider to have picked out of alternative subframe can meet to carry out son needed for energy measurement operation
The requirement of frame, energy measurement just is carried out in the subframe for carrying out cell searching and/or Time and Frequency Synchronization, if can not meet to require,
The subframe part of requirement can not be met by then further being selected in the DRX subframe not being selected.
Subframe cuts unit 13, for carrying out subframe cutting to the alternative subframe picked out, removes satisfaction setting
The redundant sub-frame of condition.
When being selected due to carrying out alternative subframe, lack overall consideration, some redundant sub-frames may be produced, therefore subframe is cut out
Cutting unit 13 needs to carry out subframe cutting to the alternative subframe picked out, and removes the redundant sub-frame for meeting to impose a condition, to protect
The card occupancy subframe of wake-up in advance as few as possible efficiently completes the operation in advance in awakening phase, saves UE power consumption.

After complete, and after having been cut to alternative subframe, wake operation execution unit 14 performs cell searching in essential subframe in advance
And/or Time and Frequency Synchronization operation, in the essential subframe picked out and carry out performing energy in remaining alternative subframe after subframe cutting
Measurement operates.
The wake-up processing unit in advance of a kind of discontinuous reception provided according to embodiments of the present invention, by successively current
The essential subframe waken up in advance for carrying out current area search and/or Time and Frequency Synchronization is picked out in the subframe of discontinuous reception, so
Afterwards based on the essential subframe picked out, it is alternative that waking up in advance for progress energy measurement is selected in the subframe of discontinuous reception
Subframe, and the alternative subframe to picking out carries out subframe cutting, it is ensured that with the subframe of wake-up in advance as few as possible efficiently
Complete to shift to an earlier date the operation in awakening phase.
Figure 12 is referred to, is the knot for waking up processing unit in advance of another discontinuous reception provided in an embodiment of the present invention
Structure schematic diagram, the device 2000 include：
First subframe module of selection 21, searched for selecting progress current area in current discontinuous reception DRX subframe
The essential subframe waken up in advance of rope.
Selecting for the essential subframe waken up in advance of cell searching is carried out, considers both of which：
The first situation：FDD (English：Frequency Division Duplex, referred to as：FDD) pattern
In order to solve the problems, such as PVS, cell searching needs staggeredly to dispatch, cell under mode of frequency division duplexing as shown in Figure 4
Search subframe selects schematic diagram, for example, when the 5ms of time cell searching and next cell searching is to hand in DRX 10ms subframes
(this accounts for preceding 5ms, then accounts for rear 5ms next times) staggered.So can ensure that will not be because PVS presence causes UE to be likely to eternal
Also search less than cell.
Second of situation：Time division duplex (English：Time Division Duplex, referred to as：TDD) pattern
Because TDD is synchronization system, PSS/SSS signals only fall in subframe 0 and subframe 5, now only need to wake up 0/5.
A kind of cell searching subframe under tdd mode as shown in Figure 5 selects schematic diagram, which show under tdd mode just
Formula wakes up the situation that subframe is 0.
Another cell searching subframe under tdd mode as shown in Figure 6 selects schematic diagram, and which show under tdd mode
It is formal wake up subframe it is non-zero and 5 situation.
First subframe module of selection 21 also includes the first determining unit 211, Time and Frequency Synchronization subframe module of selection 212.
First determining unit 211, for the channel quality according to a upper DRX, it is determined that carrying out Time and Frequency Synchronization in current DRX
Number of sub frames.
Time and Frequency Synchronization subframe module of selection 212, progress cell is needed to search if being performed for current DRX and shifting to an earlier date wake operation
Rope, and it is described picked out progress cell searching essential subframe number meet carry out Time and Frequency Synchronization number of sub frames, then without
The essential subframe for carrying out Time and Frequency Synchronization need to additionally be selected.
If Time and Frequency Synchronization subframe module of selection 212, which is additionally operable to current DRX, which performs wake operation in advance, need not carry out cell
Search, then the essential subframe for carrying out Time and Frequency Synchronization is selected in current DRX subframe.
After establishing cell searching and needing the subframe that wakes up in advance, Time and Frequency Synchronization (timing tracking and frequency are next determined
Tracking) stage needs the subframe selected.
Each DRX, which shifts to an earlier date awakening phase, needs how many individual subframes to be used for Time and Frequency Synchronization according to upper DRX channel quality shapes
Condition determines.During specific implementation, there can be the parameter of a variety of reflection channel qualities available, such as SNR, peak-to-average force ratio (English：
Peak-Average Ratio, referred to as：PAR) etc., illustrated here by taking PAR as an example.
● if the PAR that last DRX is obtained is higher than Thres1 but is less than Thres2, and next DRX Time and Frequency Synchronizations only need to account for
With two descending sub frames.
● if the PAR that last DRX is obtained is higher than Thres2, and next DRX Time and Frequency Synchronizations only need to take 1 descending son
Frame.
● if the PAR that last DRX is obtained is less than Thres1, and next DRX Time and Frequency Synchronizations need to wake up 4 descending sub frames.
The schematic diagram of comprising filtering operation the DRX cycle shown in Fig. 7 is referred to, current DRX obtains a PAR,
Then the value can be obtained F_PAR with history filtering value filtering, filtering mode is filtered using Alpha, i.e., using formula (1)：
F_PAR (n+1)=PAR (n+1) * Alpha+ (1-Alpha) * F_PAR (n) ... formula (1)
Alpha acquiescences selection 1/4.
After the number of sub frames that Time and Frequency Synchronization needs wake up is established, enter one on the basis of cell search phase has selected subframe
The descending sub frame number that step selection needs additionally to wake up (if this DRX need not start cell searching when waking up, omits cell
Search step, directly select Time and Frequency Synchronization subframe), specifically chosen mode is：
Pushed away forward from the formal subframe that wakes up, until required descending sub frame number is satisfied.If cell search phase has been called out
Descending sub frame number of waking up can meet Time and Frequency Synchronization demand, then without additionally waking up.Illustrated below for different scenes (under
Multicast broadcast multimedia service (English is not accounted in the example in face：Multimedia Broadcast Multicast
Service, referred to as：MBMS) the configuration of subframe, that is, assume there is no MBMS subframes)：
The subframe of wake-up in advance of cell searching and Time and Frequency Synchronization under fdd mode as shown in Figure 8 selects schematic diagram, it is assumed that
This DRX Time and Frequency Synchronization needs to wake up 4 subframes in advance, as seen from Figure 8, because cell search phase has waken up number of sub frames in advance
More than 4, therefore even if after considering Time and Frequency Synchronization, subframe is waken up without extra again.
The subframe of wake-up in advance of cell searching and Time and Frequency Synchronization under tdd mode as shown in Figure 9 selects schematic diagram, it is assumed that
This DRX Time and Frequency Synchronization needs to wake up 2 subframes in advance, and it is descending son that TDD sub-frame formats, which are configured to now only subframe 0/5,
Frame, as seen from Figure 9, when only considering cell searching, current DRX is without additionally waking up, but after considering Time and Frequency Synchronization, need in advance several two
Individual descending sub frame is waken up.
Second subframe module of selection 22, for based on the essential subframe picked out, being chosen in the subframe of the DRX
Choosing carries out the alternative subframe waken up in advance of energy measurement, wherein, the alternative subframe is a part for the essential subframe, or
Whole including the essential subframe and at least one subframe not being selected in the subframe of the DRX.
Second subframe module of selection 22 includes synchronized cells subframe module of selection 221, asynchronous cell subframe module of selection 222
With map unit 223.
Synchronized cells subframe module of selection 221, for being calculated backward from first essential subframe, if the essential subframe
Number meets the subframe demand number for synchronizing the energy measurement of cell, then without additionally selecting the energy for synchronizing cell
The alternative subframe of measurement, otherwise, at least one subframe is additionally selected from the subframe not being selected of the DRX, until meeting
Synchronize the demand number of the alternative subframe of the energy measurement of cell.
Asynchronous cell subframe module of selection 222, if for the essential subframe selected and synchronizing measuring for cell
The number sum of the alternative subframe of amount meets the subframe demand number for carrying out the energy measurement of asynchronous cell, then without additionally selecting
The alternative subframe of the energy measurement of asynchronous cell is carried out, otherwise, by timing position not chosen from the DRX of each asynchronous cell
Alternative subframe corresponding to being selected in the subframe of choosing.
Map unit 223, for the alternative subframe of the energy measurement of the progress picked out asynchronous cell to be mapped to
On the position of the alternative subframe for the synchronized cells picked out.
After essential subframe has been selected (cell searching and Time and Frequency Synchronization), restart the selection (energy measurement) of alternative subframe.
Alternative selecting for subframe is carried out in two stages：
● synchronized cells subframe is selected
● asynchronous cell subframe is selected
Synchronized cells subframe picking rule：
● from first essential subframe to pusher, if essential subframe meet demand, no longer wakes up other subframes；
If ● essential subframe still can not meet demand, other available subframes are additionally selected, until the demand of synchronized cells
It is satisfied；
Asynchronous cell subframe picking rule：
If ● the measurement demand of asynchronous cell can be met by having selected subframe (essential+alternative), no longer select other subframes；
● if the measurement demand of asynchronous cell can not be met, corresponding son is selected by the timing position of each asynchronous cell
Frame；
● the wake-up subframe of asynchronous cell will be finally mapped to onto the position subframe of synchronized cells (if some asynchronous subframe
Among two synchronous subframes, then the two synchronous subframes are required for being selected)；
In the energy measurement stage, no matter synchronized cells or asynchronous cell, specifically select how many individual subframes depend on it is specific
Two dimensions realized：
1, single subdistrict is in order to meet number of sub frames needed for measurement accuracy under different bandwidth；In general, bandwidth is smaller, it is required
Number of sub frames is about more, and bandwidth is bigger, and required number of sub frames is fewer；
2, UE the multiple cells of synchronization parallel processing ability；In general, bandwidth is smaller, (caching and amount of calculation are got over
It is small), parallel ability is stronger；Bandwidth is bigger, and required number of sub frames is more；
Referring to Fig. 10, selecting schematic diagram completely to wake up subframe in advance, we illustrate by taking 5M Measurement bandwidths as an example
The picking rule of alternative subframe, it is assumed that the cell of each 5M bandwidth needs 4 subframes to survey standard, and UE can handle parallel it is 4 small
Area, it is assumed that now have 6 synchronized cells, 2 asynchronous cells, accompanying drawings are as follows：
It can be seen that when only considering synchronized cells, 3 alternative subframes are additionally picked after essential subframe, are being considered
During asynchronous cell, now subframe 9,0,1, the 2 also extra disposal ability with 2 cells, therefore the processing of asynchronous cell can be positioned over
This, but consider the subframe head of itself and synchronized cells and do not line up, the subframe 2 of asynchronous cell has actually occupied synchronized cells
Subframe 3, wake up duration based on synchronized cells due to final to count, therefore the subframe 3 of final synchronized cells must also obtain
To wake up.
What deserves to be explained is the number of the synchronized cells or asynchronous cell if necessary to progress energy measurement is more, can
The energy measurement of synchronized cells or asynchronous cell can not be fully finished by distributing to main plot and carrying out the subframe of wake operation in advance
Operation, then in this case, the remaining operations of energy measurement can also be carried out in formal awakening phase.
Subframe cuts unit 23, for carrying out subframe cutting to the alternative subframe picked out, removes satisfaction setting
The redundant sub-frame of condition.
Wake operation execution unit 24 in advance, for remaining after the essential subframe picked out and progress subframe cutting
Under alternative subframe on perform shift to an earlier date wake operation.
When essential subframe+alternative subframe all after the completion of, enter subframe and cut the stage, when why having a step because by
After aforesaid way progress subframe is selected, some redundant sub-frames may be produced (because synchronized cells and asynchronous cell are chosen by cell
Choosing, lack overall consideration).Cut and carried out only for alternative subframe, it is elapsed forward from the formal subframe that wakes up, and is investigated one by one alternative
Subframe (circulation is carried out)：
● if essential subframe can meet that the measurement demand of synchronized cells or present sub-frame cannot be used for synchronized cells measurement；
● if essential subframe can meet that the measurement demand of asynchronous cell or present sub-frame cannot be used for asynchronous cell measurement.
When the two conditions are all satisfied, the subframe is no longer selected (being removed), otherwise becomes the alternative subframe
For essential subframe；
So as to which each DRX subframe in advance wakes up number and determined that the number of sub frames finally waken up is essential subframe.
Second determining unit 25, for the channel quality according to a upper DRX, called out in advance described in execution it is determined that receiving
The number for the radio-frequency channel that the data operated of waking up need to start.
Copied cells 26, for if it is determined that the number for carrying out receiving the radio-frequency channel of data is one, in a base band
The data received in one radio-frequency channel are replicated.
Processing unit 27, for being handled in the base band the data and the data of duplication received.
After subframe selects end, the second determining unit 25 can determine that this DRX shifts to an earlier date according to last DRX signal quality
Awakening phase is to receive data using single radio frequency channel reception data or using two or more radio-frequency channels, i.e., using single
Still double receipts are received, equally, the parameter of channel quality is now reacted using SNR, PAR etc., is illustrated here by taking SNR as an example,
If the SNR that last DRX is obtained is more than certain thresholding (such as 15dB), this DRX, which shifts to an earlier date awakening phase, can use single receipts, otherwise
With double receipts.
It is determined that in the case of using single receive, can two ways it is optional：
1st, radio-frequency channel corresponding to a receipts is only opened, base band is also handled using only single channel；
2nd, radio-frequency channel corresponding to a receipts is only opened, copied cells 26 is in a base band by the data duplication one of radio-frequency channel
Part, processing unit 27 is handled the data received and the data of duplication in a base band.
Because LTE gives tacit consent to UE at least two reception antennas, base band is also designed by two paths, now according to mode 2 often
Radio-frequency power consumption can be saved, can inherit that base band is existing to realize structure again.

Subframe, and the alternative subframe to picking out carries out subframe cutting, it is ensured that with the subframe of wake-up in advance as few as possible efficiently
Complete to shift to an earlier date the operation in awakening phase；And user equipment is determined when using single radio frequency channel reception data, base band is by radio frequency
The data duplication of passage is a, and the data received and the data of duplication are handled in a base band, can not change base band
