Description
The application be the applying date be August in 2010 13, application No. is 201010254678.4, it is entitled " to end
The uplink of the secondary cell at end carry out activation and deactivated method and device " patent application divisional application.
Technical field
This application involves the communications fields, more particularly to the uplink of the secondary cell of terminal (User Equipment) into
Line activating and deactivated method and apparatus.
Background technique
Following LTE-A (the Long Term Evolution Advanced) system will support the transmission belt for being up to 100MHz
Width, and LTE (Long Term Evolution) the supported maximum transmission bandwidth of standard is 20MHz, it is therefore desirable to by multiple loads
Wave is converged to realize higher transmission bandwidth.Carrier convergence (Carrier Aggregation) is 3GPP (3rd
Generation Partnership Project) in order to support following higher transmission bandwidth demand of mobile communication system and
The technology that multiple carrier waves are polymerize and carried out joint transmission proposed.It, can be with according to position of the carrier wave converged on frequency spectrum
It is divided into continuous carrier convergence and discontinuous carrier convergence, LTE-A will support both to converge scene simultaneously.3GPP is introducing carrier wave
Backwards compatibility is contemplated while convergence technology, this meaning supports carrier convergence within following very long a period of time
Do not support the terminal of carrier convergence by long-term co-existence, wherein to support the terminal of carrier convergence that can access multiple compositions simultaneously
Carrier wave, without supporting the terminal of carrier convergence to be only capable of accessing some composition carrier wave.
Application Scenarios-Example of the invention such as Fig. 1, shown in 2,3.These three application scenarios are the prioritized deployments of carrier convergence
Scene, what they were reflected is three typical case examples of carrier convergence.Carrier wave F1 and the corresponding cell of carrier wave F2 in Fig. 1
Coverage area is substantially coincident, is capable of providing similar overlay area, and it is allusion quotation that F1 and F2, which are likely located in identical carrier frequency band,
The continuity carrier convergence of type.Fig. 2 and Fig. 3 both corresponds to noncontinuity carrier convergence, and F1 and F2 are likely located at different carrier waves
Frequency band.The corresponding cell principal security spreadability of F1, the corresponding cell of F2 are mainly used for improving handling capacity.The difference of Fig. 2 and Fig. 3
It is, the corresponding antenna in cell of F2 is directed toward the border district of the corresponding cell of F1 in Fig. 3, and the application scenarios of such Fig. 3 can pole
The earth improves the handling capacity in F1 cell edge area.
In order to simplify the wireless resource management under carrier convergence scene, basic frequency (Primary will be introduced in LTE-A
Frequency concept).Correspondingly, cell corresponding with basic frequency is known as main plot (Primary cell).When terminal has
When there are biggish data transfer demands, it is considered as the transmission mode of incoming carrier convergence at this time, it is therefore desirable to new for terminal configuration
Composition carrier wave (Component Carrier), that is, configure secondary cell (Secondary cell) for terminal.In carrier convergence
Operating mode in, in order to enable terminal power consumption amount maintains normal level, introduce swashing to the downlink of secondary cell
Deactivation mechanism living.When secondary cell is in deactivation status, terminal do not have to receive corresponding control channel information (PDCCH or
PDSCH), without progress channel quality measurement.When secondary cell is active, then with said circumstances on the contrary, i.e. terminal
Receive corresponding control channel information.Media access control (media access control, abbreviation MAC) is sent by base station
The control signaling (control element) of layer activates or deactivates the downlink of corresponding secondary cell to determine terminal,
Or the downlink of some secondary cell is implicitly deactivated using timer.
Activation for secondary cell uplink is most naturally handled nothing more than two kinds.A kind of mode is and downlink
Activation as, activate the uplink of secondary cell by the way of explicitly sending activation command.This implicit commands can be with
The downlink activation order of secondary cell is sent together, can also be when uplink transmission data amount increases, then single activation pair is small
The uplink in area.Another way is implicit active mode, that is to say, that when activating the downlink of some secondary cell,
Uplink corresponding with downlink is also activated simultaneously.In this manner, it does not need explicitly to send uplink
Activation command.
The advantages of by the way of implicit commands is, for there was only the terminal of single radio frequency link (RF chain) and
Transmission bandwidth, can be adjusted to the sum of bandwidth of cell being activated by speech, be directed to what the terminal was configured without being arranged to
The sum of bandwidth of all cells (is greater than or equal to the cell being activated for the number for all cells that the terminal is configured
Number), terminal power consumption amount can be further saved in this way.The shortcomings that by the way of implicit commands, is, when needs activate newly
When the uplink of secondary cell, since the transmission bandwidth adjustment of radio frequency needs time delay, it will cause in the period where the time delay
Communication disruption or bring certain loss of data.Simultaneously because needing explicit MAC layer control signaling, also will increase corresponding
Control information content.
The advantages of by the way of implicit command, is, does not need the control information content for increasing MAC layer, reduces to control
The transmission and treatment process of signaling processed.The shortcomings that by the way of implicit command, is, for there was only the end of single radio frequency link
For end, no matter whether secondary cell is activated, and the transmission bandwidth of terminal is the sum of the bandwidth of entire configuration cell, therefore necessarily will
Increase terminal power consumption amount.But corresponding advantage is also brought simultaneously, in the uplink of the new secondary cell of activation, do not need
Transmission bandwidth is readjusted, therefore the interruption of communication and the loss of data packet will not be brought.
It should be pointed out that uplink and downlink herein can be based on 2 (system of system information block
Information block 2, abbreviation SIB2) and be associated (namely based on the association of cell), it can also be related based on terminal
Connection.
By analysis above it is found that power consumption and communication disruption are most for there was only the rf terminal of single link
Two crucial problems, regardless of being that implicit commands mode or implicit command mode cannot all solve the problems, such as simultaneously above.

Specific embodiment
Embodiments of the present invention will be described below with reference to the accompanying drawings.It is retouched in an attached drawing of the invention or a kind of embodiment
The elements and features stated can be combined with elements and features shown in one or more other drawings or embodiments.It answers
When note that for purposes of clarity, being omitted known to unrelated to the invention, those of ordinary skill in the art in attached drawing and explanation
Component and processing expression and description.
It is described with reference to Figure 4 first below according to an embodiment of the invention by the small to the pair of terminal of base station execution
The method that the uplink in area is activated.
As shown in figure 4, in step 402, determining that the radio frequency link of terminal simultaneously can received composition number of carrier wave.In step
In rapid 404, the active mode used when activating uplink is determined according to composition number of carrier wave.In a step 406, judge
Currently employed active mode and in step 404 determined by active mode whether be all implicit active mode.If worked as
Active mode used by preceding and any of identified active mode is explicit active mode (in step in step 404
It is no in 406), then the message of active mode determined by carrying is sent in a step 408.If currently employed activation side
Formula and in step 404 determined by active mode be all implicit active mode (being in a step 406 yes), then do not send out preferably
Send the message of active mode determined by carrying.
In this embodiment, if currently employed active mode is implicit active mode, next determination will use
Active mode be that explicit active mode or currently employed active mode are explicit active modes and next determination is wanted
The active mode of use is explicit active mode or currently employed active mode is explicit active mode and determination connects down
The active mode for be used is implicit active mode, then sends the message of active mode determined by carrying.If current institute
The active mode of use and the determining active mode next to be used all are implicit active modes, then do not send carrying preferably
The message of identified active mode, that is, the message as needed to send carrying active mode.
The control signaling that transmitted message can be sent by the MAC layer of base station.It is of course also possible to by terminal come
Send the message.
The secondary cell to terminal executed by base station according to another embodiment of the invention is described referring now to Fig. 5
The method that is activated of uplink.
As shown in figure 5, in step 502, determining that the radio frequency of terminal simultaneously can received composition number of carrier wave.In step
In 504, judge whether composition number of carrier wave is greater than 1.If only receiving the number of some composition carrier wave on some radio frequency link
According to (step 504 is no), then after the downlink of the secondary cell corresponding to this frequency is activated, determine in step 506
The uplink of secondary cell is activated by the way of explicitly activating, and in other words, the needs transmitted according to data decision is needed to be
The no uplink for activating the pair cell.An example of the data of a composition carrier wave is only received on some radio frequency link
Are as follows: for the carrier aggregation mode of (inter-frequency) between frequency band, using two composition carrier waves, composition carrier wave
Centre frequency is located at 800MHz, and the centre frequency of a composition carrier wave is located at 2GHz, and terminal has two radio frequency links, and one is penetrated
Frequency link corresponds to the frequency of 800MHz, and another radio frequency link corresponds to the frequency of 2G.One is only received on some radio frequency link
Another example of the data of composition carrier wave are as follows: for the carrier aggregation mode of (intra-frequency) in frequency band, use two
A composition carrier wave, centre frequency are all located at 800MHz, and terminal has two radio frequency links, at this time still can be by the two compositions
Carrier wave is assigned to corresponding two radio frequency links.
In step 508, the message comprising the determination explicit active mode to be used through the above steps is sent.In data
In the case that transmission needs, explicit activation command is sent in step 510, terminal is activated in response to the explicit activation command
Line link (step UE562).
For the transmission mode of carrier convergence, terminal is not necessarily to using symmetrical transmission, that is to say, that some carrier wave
The downlink of (cell) be used to transmit, and be not meant to that corresponding up-link carrier (cell) is also required.In the pair cell
Deactivation status into the transition process of state of activation, due to being only assigned with a carrier frequency on a radio frequency link,
Therefore other radio frequency links will not be impacted, thus only opens the uplink portion of the radio frequency link when needed
(uplink link) is divided can further to save terminal power consumption amount.In this way, communication disruption will not both be brought
Problem can also save terminal power consumption amount.
If some radio frequency link is assigned while receiving the data (step 504 is yes) of multiple composition carrier waves, root is needed
The active mode of secondary cell uplink corresponding to this multiple composition carrier wave is determined according to specific scene.Some radio frequency link
It is assigned while receiving an example of the data of multiple composition carrier waves are as follows: for the carrier aggregation mode in frequency band, use two
A composition carrier wave, centre frequency are all located at 800MHz, and terminal only has a radio frequency link, are needed at this time by the two composition carrier waves
It is assigned on the radio frequency link.In step 512, the frequent degree that uplink is activated is determined.Then, in the step 514,
The frequent degree size being activated according to uplink uses implicit active mode or explicit active mode to determine.
Preferably, it may be predetermined that a frequent degree threshold value.(the step in the case where frequent degree is greater than the threshold value
It is yes in 514), it determines in step 516 and implicit active mode is used to uplink.
Specifically, the size of the type of service and data volume that are carried according to terminal, if the type of service of terminal carrying
Belong to sudden stronger business or data volume is larger, it means that in one section of longer time, dynamically activate (or
Deactivate) operation can it is more frequent, at this time due to frequently activate operation bring communication disruption be for whole system
It is unacceptable.At this point, the transmission bandwidth of radio frequency link should be adjusted to the sum of the bandwidth of entire configuration cell, also just mean
Secondary cell uplink activation using the mode implicitly activated.
In step 518, whether judgement is current uses implicit active mode.If currently employed implicit active mode
(being yes in step 518), then need not send the message comprising implicit active mode.
If currently employed explicit active mode (being no in step 518), sent in step 520 comprising implicit activation
The message of mode.Such as the control command of MAC layer is sent by network to activate the uplink of secondary cell.
If terminal finds that secondary cellular downlink is activated (step UE564), the uplink of the pair cell is also same
When activate (UE566).In other words, it is activated in response to downlink, terminal activates corresponding uplink.In addition, using
The mode implicitly activated also can be avoided the burden due to needing to send explicit activation command brought by frequently activation.
In the case where frequent degree is less than the threshold value (being no in step 514), determine in step 522 to uplink
Using explicit active mode.
It specifically, will not if the type of service that terminal is carried at this time is not belonging to demblee form business or data traffic is little
Cause the frequent generation of activation (or deactivation) operation.It, should be by the transmission belt of radio frequency link at this time in order to save terminal power consumption amount
Width is adjusted to the sum of bandwidth of activation cell.It means that in such a scenario, being adopted for the activation of the uplink of secondary cell
It is the mode explicitly activated.
Preferably, the frequent journey of activation can be determined according to the type of service and/or data volume size that terminal is carried
Degree.Preferably, it can be responsible for collecting corresponding information (uplink data volume to be transmitted and type of service etc.) by terminal and transmitted
To base station, take by base station the decision of which kind of active mode.Decision can also be carried out according to the information being collected by terminal,
And this decision notification is executed to base station by base station.
In step 524, the message comprising explicit active mode is sent.Next in step 526, such as according to business
Needs, send explicit activation command (for example, can by MAC layer send control information), thus by the uplink of the cell
It activates (UE568).
In step 528, estimation is adjusted the required period to uplink.Specifically, estimation to uplink into
Start time and duration needed for row adjustment.In step 530, not to terminal distribution wireless resource block within the period.
Specifically, the readjustment of transmission bandwidth caused by being operated due to activation can inevitably lead to the interruption of communication
Or the loss of data volume.In order to further decrease loss of data, optimization method below can be used: due to explicitly activating
Under mode, activation command is to be issued by base station, therefore base station can be predicted when the radio frequency link of terminal will do it transmission
The adjustment of bandwidth, and how long the time that can estimate adjustment about (does not exceed 1ms) under normal circumstances, therefore in order to avoid
Loss of data during this period of time, the resource allocation algorithm of the adjustable scheduler in base station, so that during this period of time, not giving
The corresponding wireless resource block of this terminal distribution.This makes it possible to avoid the data caused by the mode of implicit commands from losing
It loses.
One embodiment of this scheme is can to think secondary cell uplink using implicit by default
Active mode, after base station is determined using explicit active mode, after sending implicit commands, then it is assumed that secondary cell uplink at this time
Using explicit active mode, the state of this active mode is always maintained at until the pair cell is deactivated.
Due to the case where in carrier convergence, there are cross scheduling (cross-scheduling), that is, in some cell
The data transmission PDSCH of other cells is indicated in PDCCH.
The side activated in the case where cross scheduling to the uplink of the secondary cell of terminal is described referring to Fig. 6
Method.
As shown in fig. 6, after step 524 or 508 uplink authorization can also be sent by downlink.In step
In rapid 532, whether judge in the transmission authorization comprising carrier wave instructions field.If the transmission authorization includes carrier wave instructions field (step
It is yes in 532), then uplink corresponding with carrier wave instructions field is activated in step 534.If the transmission authorization does not include
Carrier wave instructions field (being no in step 532) then activates uplink associated with the downlink in step 536.
Specifically, if terminal is received by some cell (cell may be that main plot may also be secondary cell) comprising carrying
The uplink to other secondary cells (being specified by CIF) of wave instructions field (Carrier Indicator Field, abbreviation CIF)
The uplink of authorization, secondary cell appointed at this time is implicitly activated.If terminal is received by some cell not comprising carrier wave
The uplink authorization of instructions field, the uplink for receiving the secondary cell of uplink authorization at this time are implicitly activated, in other words
It says, uplink corresponding with downlink is implicitly activated.Here downlink and uplink can be believed based on system
Breath block 2 (system information block 2, abbreviation SIB2) and be associated (namely based on the association of cell), can also be with
It is associated based on terminal.
There are in the case where multiple secondary cells, implicit active mode and explicit swash in a communications system for terminal
Mode living can exist simultaneously.For example, currently employed explicit active mode activates all secondary cells of terminal configuration
Uplink.Any secondary cell in these secondary cells obtains a uplink authorization, obtains uplink authorization at this time
Uplink is implicitly activated (the case where no CIF).Or the instruction according to CIF, a secondary cell in these secondary cells
Uplink is implicitly activated.But for other secondary cells in addition to this, still using explicit active mode.
The secondary cell to terminal according to an embodiment of the invention executed by base station is described referring to Fig. 7
Uplink carries out deactivated method.
As shown in fig. 7, in a step 702, determining that the radio frequency link of terminal simultaneously can received composition number of carrier wave.In step
In rapid 704, the deactivation mode to be used when deactivating uplink is determined according to composition number of carrier wave.In step 706
In, judge currently employed deactivation mode and whether the determination deactivation mode to be used all is implicit in step 704
Deactivation mode.If currently employed deactivation mode and in step 704 determined by any of deactivation mode
It is explicit deactivation mode (being in step 706 no), then sends disappearing for deactivation mode determined by carrying in step 708
Breath.If currently employed deactivation mode and in step 704 determined by deactivation mode be all implicit deactivation side
Formula (being in step 706 yes) need not then send the message of deactivation mode determined by carrying.
In this embodiment, if currently employed deactivation mode is implicit deactivation mode, next determination is wanted
The deactivation mode used for it is explicit deactivate mode or currently employed deactivation mode is explicit deactivation mode and
Determine that the deactivation side next to be used mode is explicit deactivation mode or currently employed deactivation mode is aobvious
Formula deactivates mode and determines that the deactivation mode next to be used is implicit deactivation mode, then sends determined by carrying
The message of deactivation mode.If currently employed deactivation mode and the determining deactivation mode next to be used all are
It is implicit to deactivate mode, then do not send the message of deactivation mode determined by carrying preferably, that is, take as needed to send
It takes the message of active mode.
The control signaling that transmitted message can be sent by the MAC layer of base station.It is of course also possible to by terminal come
Send the message.
The secondary cell to terminal executed by base station according to another embodiment of the invention is described referring now to Fig. 8
Uplink carry out deactivated method.
As shown in figure 8, in step 802, determining that the radio frequency link of terminal simultaneously can received composition number of carrier wave.In step
In rapid 804, judge whether composition carrier wave is greater than 1 in right amount.If only receiving the number of some composition carrier wave on some radio frequency link
According to (being in step 804 no), then determines in step 806 and uplink is deactivated using implicit deactivation mode, that is, when
After the downlink of secondary cell corresponding to this frequency is deactivated, deactivation for the uplink of the pair cell is adopted
The uplink of the pair cell is deactivated with implicit deactivated mode.That is, the downlink when the pair cell deactivates
After work, the uplink of the pair cell is also deactivated accordingly.The number of a composition carrier wave is only received on some radio frequency link
According to an example are as follows: for the carrier aggregation mode between frequency band, use two composition carrier waves, the center frequency of a composition carrier wave
Rate is located at 800MHz, and the centre frequency of a composition carrier wave is located at 2GHz, and terminal has two radio frequency links, a radio frequency link
The frequency of corresponding 800MHz, another radio frequency link correspond to the frequency of 2GHz.A composition is only received on some radio frequency link to carry
Another example of the data of wave are as follows: for the carrier aggregation mode in frequency band, using two composition carrier waves, the two compositions are carried
The centre frequency of wave is all located at 800MHz, and terminal has two radio frequency links, at this time still can be by the two composition carrier waves point
It is fitted on corresponding two radio frequency links.
It has determined explicit deactivation mode currently employed in step 808, has then been sent in step 810 comprising implicitly going
The message of active mode.If currently employed implicit deactivation mode, is not required to send the message.
After terminal determines that downlink corresponding with uplink is deactivated (UE862), terminal deactivates uplink
Link (UE864).
Some secondary cell is deactivated, it may be possible to which the signal quality of reduction or the cell due to volume of transmitted data becomes
Difference will not dispatch the cell in the time of base station section, which kind of either above-mentioned situation, all be somebody's turn to do It is not necessary to continue to retain
The uplink of cell is active, therefore, the deactivation status of the uplink of secondary cell be under the pair cell
Line link keeps binding.
If secondary cell corresponding to the radio frequency link is in deactivated state, the radio frequency link of terminal can be closed
(UE866), to further save terminal power consumption amount, while other radio frequency links will not be had an impact.
If the data (being yes in step 804) of multiple composition carrier waves are assigned while received on some radio frequency link, when
After the downlink of secondary cell corresponding to this frequency is deactivated, deactivation for the uplink of the pair cell is needed
The deactivation mode of the uplink is determined according to the active mode of the uplink of the pair cell.In step 812, judge
Whether the active mode of uplink is implicit active mode.
If the uplink of the pair cell uses implicit active mode (being yes in step 812), determine in step 814
Corresponding uplink also deactivates the uplink of the pair cell using implicit deactivation mode.That is, working as the pair
After the downlink of cell deactivates, which is also deactivated accordingly.The reason is that, if uplink
Link uses implicit active mode, illustrates that the transmission bandwidth of terminal is the sum of the bandwidth of entire configuration cell, even if using aobvious
The mode of formula deactivates the uplink of secondary cell, and since other cells still have data transmission, entire radio frequency link can not
It closes, therefore the advantage for saving terminal power consumption amount brought by explicit way is little, but also to handle and explicit deactivate life
It enables, brings additional control signaling processing load.
It has determined explicit deactivation mode currently employed in step 816, has then sent in step 818 comprising implicitly going
The message of active mode.If currently employed implicit deactivation mode, is not required to send the message.
In the case where terminal determines that downlink corresponding with uplink is deactivated (UE868), terminal is deactivated
Uplink (UE860) living.
If the uplink of the pair cell uses explicit active mode (being no in step 812), in step 820 really
Fixed corresponding uplink also uses explicit deactivation mode.Namely when do not need the uplink for data transmit
When, for example, can send specified deactivation control signaling by MAC layer deactivates the uplink.In step 822, it sends
Message comprising explicitly deactivating mode.The reason is that, illustrating the transmission of terminal if uplink uses explicit active mode
Bandwidth is the sum of the bandwidth of activation cell, and the downlink of some secondary cell is transmitted for data, does not represent the upper of the pair cell
Line link is also used for data transmission (data volume of uplink and downlink link have asymmetry), therefore, immediately will not by
The secondary cell uplink used deactivates, and the transmission bandwidth of radio frequency link can be adjusted immediately, saves terminal consumption to reach
The purpose of electricity.
It can be swashed by MAC layer about the message described above for carrying active mode and the message for carrying deactivation mode
Work/deactivation control signaling is realized.It can be multiplexed display activation command or explicit deactivation command within the message.
By above description it is found that according to different scenes, the activation/deactivation process of secondary cell uplink both can be with
It is explicit mode, is also possible to implicit mode, therefore it is contemplated that distinguishing in the design of activation/deactivation control signaling
Different situations.
The MAC sub-header (Sub-header) of MAC layer activation/deactivation control signaling can use lattice as shown in the table
Formula, wherein the digital representation bit number in bracket.
| R(1) | R(1) | E(1) | LCID(5) |
Wherein, first R (1) mark retains 1 bit；Second R (1) mark retains 1 bit；Third E indicates the son
Identify after the sub-header that there is also sub-headers, 0 to identify the sub-header whether there is also sub-header after header, 1 in bracket
Sub-header is not present later；LCID (logicalchannel ID) identifies logic channel example, is used for activation/deactivation.
MAC payload (payload) can use format as shown in the table.
| R2(1) | R1(1) | R0(1) | Cell4(1) | Cell3(1) | Cell2(1) | Cell1(1) | Cell0(1) |
Terminal can distribute a cell index when using the transmission mode of carrier convergence for the cell of each addition
(cell index).Here enumerate be terminal at most and meanwhile converge 5 cells the case where, in this case, 5 bit foots
Enough indicate activation and deactivation process of the terminal under carrier convergence mode.The meaning of each bit is explained in turn below:

Cell2: activation or deactivating cell index the cell for being 2.1 indicates activation, and 0 indicates to deactivate.
Cell3: activation or deactivating cell index the cell for being 3.1 indicates activation, and 0 indicates to deactivate.
Cell4: activation or deactivating cell index the cell for being 4.1 indicates activation, and 0 indicates to deactivate.
R0: identify behind the byte whether there are also other bytes.1 indicates that there are also other bytes, 0 to indicate all biographies below
Defeated content has finished.(bit is only effective under the explicit activation/deactivation mode of uplink).
R1: it is effective to uplink or downlink for identifying the order.1 indicates effective to downlink, and 0 indicates effective to uplink.It (should
Bit is only effective under the explicit activation/deactivation mode of uplink).
R2: identify whether the order is explicit or implicit activation/deactivation order.1 indicates implicit command, and 0 indicates explicit
Order.
In the activation/deactivation control signaling of MAC layer, define whether the order of 1 bit identification is explicit or implicit sharp
Work/deactivation command.In the activation/deactivation control signaling of MAC layer, define the order of 1 bit identification be to uplink or
Downlink effectively (bit is only effective under the explicit activation/deactivation mode of uplink).In the activation/deactivation of MAC layer
In control signaling, define behind the 1 bit identification byte whether also (bit is only in the explicit of uplink for others bytes
Under activation/deactivation mode effectively).
The activation/deactivation control signaling of MAC layer enumerated above is only exemplary, and is not limiting.It is practical
On, it can also modify as needed.For example, 1 or 0 can indicate other meanings.The number of cells that terminal can converge
5 are also not limited to, can be other numbers.
