Description
The divisional application that the application is the applying date is on August 13rd, 2010, application number is 201010254678.4, denomination of invention is the patent application of " activate the up link of the secondary community of terminal and the method for deexcitation and device ".
Technical field
The application relates to the communications field, particularly relates to the method and apparatus up link of the secondary community of terminal (User Equipment) being carried out to activation and deexcitation.
Background technology
The transmission bandwidth that following LTE-A (the Long Term Evolution Advanced) system will be supported up to 100MHz, and LTE (Long Term Evolution) the supported maximum transmission bandwidth of standard is 20MHz, therefore need multiple carrier wave to be carried out converge to realize higher transmission bandwidth.Carrier convergence (Carrier Aggregation) is that 3GPP (3rd GenerationPartnership Project) is in order to support the technology of multiple carrier aggregation being carried out joint transmission that the transmission bandwidth demand that following mobile communication system is higher proposes.According to the position of converged carrier wave on frequency spectrum, continuous carrier can be divided into converge and discontinuous carrier convergence, LTE-A will support that these two kinds are converged scenes simultaneously.3GPP contemplates backwards compatibility while introducing carrier convergence technology, this means within a period of time that future is very long, support carrier convergence and do not support that the terminal of carrier convergence is by long-term co-existence, wherein, support that the terminal of carrier convergence can access multiple composition carrier wave simultaneously, and do not support that the terminal of carrier convergence only can access some composition carrier waves.
Application Scenarios-Example of the present invention as Fig. 1,2, shown in 3.These three application scenarioss are prioritized deployment scenes of carrier convergence, three typical apply examples of what they reflected is carrier convergence.The cell coverage area that carrier wave F1 in Fig. 1 and carrier wave F2 is corresponding overlaps substantially, can provide similar overlay area, F1 and F2 may be positioned at identical carrier frequency band, is typical continuity carrier convergence.Fig. 2 and Fig. 3 corresponds to noncontinuity carrier convergence, F1 and F2 may be positioned at different carrier frequency bands.The community principal security spreadability that F1 is corresponding, the community that F2 is corresponding is mainly used in improving throughput.The difference of Fig. 2 and Fig. 3 is, the antenna in cell that in Fig. 3, F2 is corresponding points to the border district of community corresponding to F1, and the application scenarios of such Fig. 3 greatly can improve the throughput in F1 cell edge area.
In order to simplify the RRM under carrier convergence scene, the concept of basic frequency (Primary Frequency) will be introduced in LTE-A.Correspondingly, corresponding with basic frequency community is called main plot (Primary cell).When terminal has larger data transfer demands, now should consider the transmission mode that incoming carrier converges, therefore needing for the new composition carrier wave (ComponentCarrier) of terminal configuration, that is, is the secondary community (Secondary cell) of terminal configuration.In the mode of operation of carrier convergence, in order to make terminal power consumption amount maintain normal level, introduce the activation deexcitation mechanism to the down link of secondary community.When secondary community is in deactivation status, terminal need not receive corresponding control channel information (PDCCH or PDSCH), also need not carry out channel quality measurement.When secondary community is in state of activation, then contrary with said circumstances, namely terminal receives corresponding control channel information.Send media interviews by base station and control (media access control, being called for short MAC) control signal (control element) of layer decides terminal and activates or the down link of the corresponding secondary community of deexcitation, or use timer to carry out the down link of certain secondary community of implicitly deexcitation.
For the activation of secondary cell uplink, the most naturally process nothing more than two kinds.A kind of mode is the same with the activation of down link, adopts the mode of explicit transmission activation command to activate the up link of secondary community.This implicit commands can send together with the downlink activation order of secondary community, and also can work as uplink transmission data amount increases time the more independent up link activating secondary community.Another kind of mode is implicit expression active mode, and that is, when activating the down link of certain secondary community, the up link corresponding to down link has also been activated simultaneously.In this manner, explicitly is not needed to send uplink activation order.
The advantage of the mode of implicit commands is adopted to be, for only having the terminal of single radio frequency link (RF chain), transmission bandwidth can be adjusted to the bandwidth sum of the community be activated, instead of be set to the bandwidth sum (number of all communities configured for this terminal is more than or equal to the community number be activated) of all communities configured for this terminal, terminal power consumption amount can be saved further like this.Adopt the shortcoming of the mode of implicit commands to be, when needing the up link activating Xin Fu community, because the transmission bandwidth adjustment of radio frequency needs time delay, the communication disruption in the time period at this time delay place can be caused or bring certain loss of data.Simultaneously owing to needing explicit MAC layer control signal, corresponding control information quantity also can be increased.
Adopt the advantage of the mode of implicit command to be, do not need the control information quantity increasing MAC layer, decrease the transmission to control signal and processing procedure.Adopt the shortcoming of the mode of implicit command to be, for only having the terminal of single radio frequency link, no matter whether secondary community is activated, and the transmission bandwidth of terminal is the bandwidth sum of whole allocating cell, therefore must by increase terminal power consumption amount.But also bring corresponding advantage simultaneously, when activating the up link of Xin Fu community, not needing to readjust transmission bandwidth, therefore can not bring the interruption of communication and the loss of packet.
It is to be noted, up link herein and down link can based on system information block 2 (system information block 2, be called for short SIB2) and be associated (that is, based on the association of community), also can be associated based on terminal.
From analysis above, for only having the rf terminal of single link, power consumption and communication disruption are the two problems of most critical, and are the problem that implicit commands mode or implicit command mode all can not solve above simultaneously.

Embodiment
With reference to the accompanying drawings embodiments of the invention are described.The element described in an accompanying drawing of the present invention or a kind of execution mode and feature can combine with the element shown in one or more other accompanying drawings or execution mode and feature.It should be noted that for purposes of clarity, accompanying drawing and eliminate expression and the description of unrelated to the invention, parts known to persons of ordinary skill in the art and process in illustrating.
First the method that the up link being described with reference to Figure 4 the secondary community to terminal performed by base station according to an embodiment of the invention below activates.
As shown in Figure 4, in step 402, the composition number of carriers that the radio frequency link of terminal can receive simultaneously is determined.In step 404, the active mode adopted when activating up link is determined according to composition number of carriers.In a step 406, judge current adopted active mode and in step 404 determined active mode whether be all implicit expression active mode.If any one is explicit active mode (being no in a step 406) in current adopted active mode and in step 404 determined active mode, then send the message of carrying determined active mode in a step 408.If current adopted active mode and in step 404 determined active mode are all implicit expression active mode (being yes in a step 406), then preferably do not send the message of carrying determined active mode.
In this embodiment, if current adopted active mode is implicit expression active mode and determines that the active mode that next will adopt is explicit active mode, or current adopted active mode is explicit active mode and determines that the active mode that next will adopt is explicit active mode, or current adopted active mode is explicit active mode and determines that the active mode that next will adopt is implicit expression active mode, then send the message of carrying determined active mode.If current adopted active mode and determine that the active mode that next will adopt is all implicit expression active mode, then preferably do not send the message of carrying determined active mode, that is, send the message of carrying active mode as required.
The control signal that the message sent can be sent by the MAC layer of base station.Certainly, also this message can be sent by terminal.
The method that the up link of the secondary community to terminal performed by base station described according to another embodiment of the invention referring now to Fig. 5 activates.
As shown in Figure 5, in step 502, the composition number of carriers that the radio frequency of terminal can receive simultaneously is determined.In step 504, judge whether composition number of carriers is greater than 1.If receive only the data (step 504 is no) of some composition carrier waves on certain radio frequency link, then after the down link of the secondary community corresponding to this frequency is activated, determine in step 506 to adopt the mode of explicit activation to activate the up link of secondary community, in other words, the up link determining whether to activate this secondary community according to the needs of transfer of data is needed.The example that certain radio frequency link receives only the data of a composition carrier wave is: the carrier aggregation mode of (inter-frequency) between for frequency band, use two composition carrier waves, the centre frequency of a composition carrier wave is positioned at 800MHz, the centre frequency of a composition carrier wave is positioned at 2GHz, terminal has two radio frequency links,, a frequency of the corresponding 800MHz of radio frequency link, the frequency of the corresponding 2G of another radio frequency link.Another example that certain radio frequency link receives only the data of a composition carrier wave is: for the carrier aggregation mode of (intra-frequency) in frequency band, use two composition carrier waves, centre frequency is all positioned at 800MHz, terminal has two radio frequency links, now still can by these two composition allocation of carriers to two corresponding radio frequency links.
In step 508, transmission comprises the message being determined the explicit active mode that will adopt by above-mentioned steps.When transfer of data needs, send explicit activation command in step 510, terminal response activates up link (step UE562) in this explicit activation command.
For the transmission mode of carrier convergence, might not require that terminal adopts symmetrical transmission, that is the down link of certain carrier wave (community) is used to transmission, and does not mean that corresponding up-link carrier (community) is also required.Deactivation status in this secondary community is in the transition process of state of activation, owing to being only assigned with a carrier frequency on a radio frequency link, therefore can not impact other radio frequency link, the uplink part (uplink link) of only opening this radio frequency link thus when needing can further save terminal power consumption amount.Adopt in this way, both can not bring the problem of communication disruption, also can save terminal power consumption amount.
If certain radio frequency link is assigned with the data (step 504 is yes) receiving multiple composition carrier waves simultaneously, then need the active mode deciding the secondary cell uplink corresponding to this multiple composition carrier wave according to concrete scene.The example that certain radio frequency link is assigned with the data simultaneously receiving multiple composition carrier wave is: for the carrier aggregation mode in frequency band, use two composition carrier waves, centre frequency is all positioned at 800MHz, terminal only has a radio frequency link, now needs these two composition allocation of carriers on this radio frequency link.In step 512, the frequent degree that up link is activated is determined.Then, in the step 514, the frequent degree size be activated according to up link is determined to adopt implicit expression active mode or explicit active mode.
Preferably, a frequent degree threshold value can be pre-determined.When frequent degree is greater than this threshold value (being yes in step 514), determine in step 516 to adopt implicit expression active mode to up link.
Particularly, the type of service carried according to terminal and the size of data volume, if the type of service of terminal carrying belongs to sudden stronger business or data volume is larger, this means within the time of one longer, the operation of dynamic activation (or deexcitation) can be relatively more frequent, and the communication disruption now brought due to activation manipulation is frequently unacceptable for whole system.Now, the transmission bandwidth of radio frequency link should be adjusted to the bandwidth sum of whole allocating cell, what also just mean the activation employing of secondary cell uplink is the mode that implicit expression activates.
In step 518, judge currently whether have employed implicit expression active mode.If current employing implicit expression active mode (being yes in step 518), then need not send the message comprising implicit expression active mode.
If the explicit active mode of current employing (being no in step 518), then send the message comprising implicit expression active mode in step 520.Such as sent the control command of MAC layer by network to activate the up link of secondary community.
If terminal finds that secondary cellular downlink is activated (step UE564), the up link of Ze Gaifu community also activates (UE566) simultaneously.In other words, be activated in response to down link, terminal activates corresponding up link.In addition, the mode adopting implicit expression to activate also can avoid the burden owing to needing frequently to activate the explicit activation command of transmission brought.
When frequent degree is less than this threshold value (being no in step 514), determine in step 522 to adopt explicit active mode to up link.
Particularly, if the type of service that now terminal carries does not belong to demblee form business or data traffic is little, the frequent generation that activation (or deexcitation) operates can not be caused.Now in order to save terminal power consumption amount, the transmission bandwidth of radio frequency link should be adjusted to the bandwidth sum of activation cell.This means, in such a scenario, the mode of explicit activation that what the activation for the up link of secondary community adopted is.
Preferably, the type of service that can carry according to terminal and/or data volume size determine the frequent degree activated.Preferably, can be responsible for collecting corresponding information (up data volume waiting for transmission and type of service etc.) and being transferred to base station by terminal, carry out by base station the decision-making taking which kind of active mode.Also can carry out decision-making by terminal according to the information collected, and by this decision notification to base station, be performed by base station.
In step 524, the message comprising explicit active mode is sent.Next, in step 526, such as, according to the needs of business, explicit activation command (such as, can be sent control information by MAC layer) is sent, thus by the uplink activation (UE568) of this community.
In step 528, estimate the period needed for up link is adjusted.Particularly, estimate to adjust up link needed for start time and duration.In step 530, within this period not to terminal distribution wireless resource block.
Particularly, the readjusting of transmission bandwidth caused due to activation manipulation inevitably can cause the interruption of communication or the loss of data volume.In order to reduce loss of data further, following optimization method can be adopted: due under explicit active mode, activation command is sent by base station, therefore base station can predict that the radio frequency link of the terminal when can carry out the adjustment of transmission bandwidth, and the time can estimating adjustment probably for how long (generally can not more than 1ms), therefore in order to avoid loss of data during this period of time, base station can adjust the resource allocation algorithm of scheduler, make within this time period, do not give the corresponding wireless resource block of this terminal distribution.This makes it possible to the loss of data avoiding the mode due to implicit commands to cause.
An embodiment of this scheme is, what can think that secondary cell uplink adopts in default situations is implicit expression active mode, after base station determines to adopt explicit active mode, after sending implicit commands, what then think that now secondary cell uplink adopts is explicit active mode, and the state of this active mode remains to till this secondary community is deactivated always.
Due in carrier convergence, there is the situation of cross scheduling (cross-scheduling), that is, in the PDCCH of certain community, indicate the transfer of data PDSCH of other communities.
Method when being described in cross scheduling referring to Fig. 6, the up link of the secondary community of terminal activated.
As shown in Figure 6, after step 524 or 508, uplink mandate can also be sent by down link.In step 532, judge whether comprise carrier wave instructions field in this transmission mandate.If this transmission authorization packets is containing carrier wave instructions field (being yes in step 532), then activate the up link corresponding with carrier wave instructions field in step 534.If this transmission mandate does not comprise carrier wave instructions field (being no in step 532), then activate the up link be associated with this down link in step 536.
Particularly, if terminal is received by certain community (this community also may may be secondary community for main plot) comprise carrier wave instructions field (Carrier Indicator Field, be called for short CIF) the uplink mandate to other secondary communities (being specified by CIF), now the up link of appointed secondary community is activated by implicit expression.If terminal receives the uplink mandate not comprising carrier wave instructions field by certain community, the up link now receiving the secondary community of uplink mandate is activated by implicit expression, and in other words, the up link corresponding with down link is activated by implicit expression.Here down link and up link based on system information block 2 (system information block 2 is called for short SIB2) be associated (that is, based on the association of community), also can be associated based on terminal.
When there is multiple secondary community for a terminal, implicit expression active mode and explicit active mode can exist simultaneously in a communications system.Such as, the explicit active mode of current employing activates the up link of all secondary community of a terminal configuration.Arbitrary secondary community in these secondary communities obtains a uplink mandate, and the up link now obtaining uplink mandate is activated (situation without CIF) by implicit expression.Or according to the instruction of CIF, the up link of the Ge Fu community in these secondary communities is activated by implicit expression.But for other secondary communities in addition, what still adopt is explicit active mode.
The up link describing the secondary community to terminal performed by base station according to an embodiment of the invention referring to Fig. 7 carries out the method for deexcitation.
As shown in Figure 7, in a step 702, the composition number of carriers that the radio frequency link of terminal can receive simultaneously is determined.In step 704, the deexcitation mode that will adopt when deexcitation up link is determined according to composition number of carriers.In step 706, judge current adopted deexcitation mode and determine whether the deexcitation mode that will adopt is all implicit expression deexcitation mode in step 704.If any one is explicit deexcitation mode (being no in step 706) in current adopted deexcitation mode and in step 704 determined deexcitation mode, then send the message of carrying determined deexcitation mode in step 708.If current adopted deexcitation mode and in step 704 determined deexcitation mode are all implicit expression deexcitation mode (being yes in step 706), then need not send the message of carrying determined deexcitation mode.
In this embodiment, if current adopted deexcitation mode is implicit expression deexcitation mode and determines that the deexcitation mode that next will adopt is explicit deexcitation mode, or current adopted deexcitation mode is explicit deexcitation mode and determines that deexcitation side's mode that next will adopt is explicit deexcitation mode, or current adopted deexcitation mode is explicit deexcitation mode and determines that the deexcitation mode that next will adopt is implicit expression deexcitation mode, then send the message of carrying determined deexcitation mode.If current adopted deexcitation mode and determine that the deexcitation mode that next will adopt is all implicit expression deexcitation mode, then preferably do not send the message of carrying determined deexcitation mode, that is, send the message of carrying deexcitation mode as required.
The control signal that the message sent can be sent by the MAC layer of base station.Certainly, also this message can be sent by terminal.
The up link of the secondary community to terminal performed by base station described according to another embodiment of the invention referring now to Fig. 8 carries out the method for deexcitation.
As shown in Figure 8, in step 802, the composition number of carriers that the radio frequency link of terminal can receive simultaneously is determined.In step 804, judge whether composition carrier wave is greater than 1 in right amount.If certain radio frequency link receives only the data (being no in step 804) of some composition carrier waves, then determine in step 806 to adopt implicit expression deexcitation mode to carry out deexcitation up link, namely, after the down link of the secondary community corresponding to this frequency is deactivated, for the deexcitation of the up link of this secondary community, adopt the up link of this secondary community of mode deexcitation of implicit expression deexcitation.That is, after the down link deexcitation of this secondary community, the up link of this secondary community is also deactivated accordingly.The example certain radio frequency link receiving only the data of a composition carrier wave is: for the carrier aggregation mode between frequency band, use two composition carrier waves, the centre frequency of a composition carrier wave is positioned at 800MHz, the centre frequency of a composition carrier wave is positioned at 2GHz, terminal has two radio frequency links, the frequency of a corresponding 800MHz of radio frequency link, the frequency of the corresponding 2GHz of another radio frequency link.Another example certain radio frequency link receiving only the data of a composition carrier wave is: for the carrier aggregation mode in frequency band, use two composition carrier waves, the centre frequency of these two composition carrier waves is all positioned at 800MHz, terminal has two radio frequency links, now still can by these two composition allocation of carriers on two radio frequency links of correspondence.
Determine in step 808 currently to have employed explicit deexcitation mode, then send the message comprising implicit expression deexcitation mode in step 810.Have employed implicit expression deexcitation mode if current, then do not need to send this message.
(UE862) after the down link corresponding with up link is deactivated is determined, terminal deexcitation up link (UE864) in terminal.
Certain secondary community is deactivated, it may be the minimizing due to volume of transmitted data, or the signal quality of this community is deteriorated, or this community can not be dispatched in the period in base station, no matter be which kind of above-mentioned situation, all there is no need to continue to retain the up link of this community and be in state of activation, therefore, the down link of the deactivation status Shi Yugaifu community of the up link of secondary community keeps binding.
If the secondary community corresponding to this radio frequency link is in the state of deexcitation, the radio frequency link that can close a terminal (UE866), to save terminal power consumption amount further, also can not have an impact to other radio frequency link simultaneously.
The data (being yes in step 804) simultaneously receiving multiple composition carrier waves if certain radio frequency link is assigned with, then after the down link of the secondary community corresponding to this frequency is deactivated, for the deexcitation of the up link of this secondary community, need the deexcitation mode determining this up link according to the active mode of the up link of this secondary community.In step 812, whether the active mode judging up link is implicit expression active mode.
The up link of Ruo Gaifu community adopts implicit expression active mode (being yes in step 812), then determine that corresponding up link also adopts the up link of this secondary community of deexcitation mode deexcitation of implicit expression in step 814.That is, after the down link deexcitation of this secondary community, up link corresponding to this secondary community is also deactivated accordingly.Reason is, if up link adopts the active mode of implicit expression, illustrate that the transmission bandwidth of terminal is the bandwidth sum of whole allocating cell, even if adopt the up link of the secondary community of explicit mode deexcitation, because still there is transfer of data other communities, whole radio frequency link can not be closed, and therefore the advantage of saving terminal power consumption amount brought of explicit way is little, but also explicit deactivation command will be processed, bring extra control signal processing load.
Determine in step 816 currently to have employed explicit deexcitation mode, in step 818, then send the message comprising implicit expression deexcitation mode.Have employed implicit expression deexcitation mode if current, then do not need to send this message.
When terminal determines that the down link corresponding with up link is deactivated (UE868), terminal deexcitation up link (UE860).
The up link of Ruo Gaifu community adopts explicit active mode (being no in step 812), then determine that corresponding up link also adopts explicit deexcitation mode in step 820.Namely when not needing this up link for transfer of data, such as, this up link of deexcitation control signal deexcitation of specifying can be sent by MAC layer.In step 822, the message comprising explicit deexcitation mode is sent.Reason is, if up link adopts explicit active mode, illustrate that the transmission bandwidth of terminal is the bandwidth sum of activation cell, the down link of certain secondary community is used for transfer of data, the up link not representing this secondary community is also used to transfer of data (data volume of uplink and downlink link has asymmetry), therefore, immediately by not by the secondary cell uplink deexcitation used, the transmission bandwidth of radio frequency link can be adjusted immediately, to reach the object of saving terminal power consumption amount.
Can be realized by MAC layer activation/deactivation control signal with the message of carrying deexcitation mode about above-described message of carrying active mode.Within the message can multiplexing display activation command or explicit deactivation command.
From description above, according to different scenes, the activation/deactivation process of secondary cell uplink both can be explicit mode, also can be the mode of implicit expression, therefore can consider to distinguish different situations in the design of activation/deactivation control signal.
The MAC sub-header (Sub-header) of MAC layer activation/deactivation control signal can adopt form as shown in the table, wherein, and the numeral bit number in bracket.
| R(1) | R(1) | E(1) | LCID(5) |
Wherein, first R (1) mark reservation 1 bit; Second R (1) mark reservation 1 bit; Whether the 3rd E also exists sub-header after representing this sub-header, also there is sub-header, there is not sub-header after 0 this sub-header of mark after 1 this sub-header of mark in bracket; LCID (logicalchannel ID) tagging logic channel example, for activation/deactivation.
MAC payload (payload) can adopt form as shown in the table.
| R2(1) | R1(1) | R0(1) | Cell4(1) | Cell3(1) | Cell2(1) | Cell1(1) | Cell0(1) |

R1: identifying this order is to up or effectively descending.1 represents effectively descending, and 0 represents effectively up.(this bit is only effective under the explicit activation/deactivation mode of up link).
R2: whether identify this order is explicit or the order of implicit expression activation/deactivation.1 represents implicit command, and 0 represents implicit commands.
Whether in the activation/deactivation control signal of MAC layer, defining this order of 1 bit identification is explicit or the order of implicit expression activation/deactivation.In the activation/deactivation control signal of MAC layer, defining this order of 1 bit identification is to up or descending effectively (this bit is only effective under the explicit activation/deactivation mode of up link).In the activation/deactivation control signal of MAC layer, to define after this byte of 1 bit identification the byte (this bit only under the explicit activation/deactivation mode of up link effectively) whether also having other.
The activation/deactivation control signal of MAC layer cited is above exemplary, is not restrictive.In fact, can also modify as required.Such as, 1 or 0 implication that can represent other.The number of cells that terminal can converge also is not limited to 5, can be other number.
