Description
Technical field
The present invention relates to communication system, particularly relate to the method and apparatus of synchronous UE and SeNB in the use of new configuration parameter in dual link communication system.
Background technology
According to current dual link (dualconnectivity, DC) state, may for be configured with multiple community from cell set (SCG) on small-cell base station (SeNB), one in these communities as Special Main community (SPcell), other as common from community (Scells).The Main Function of SPcell carries out PUCCH transmission.Reached at present following consistent: SPcell, after being added, is always in state of activation in its whole life cycle, the Pcell defined in this and R10 is similar.For the community of SCG, no matter it is SPcell or Scell, and all must have the transmission of autonomous ascending control information (UCI), such as uplink SRS, up PUCCH and up CQI/PMI/RI etc., certainly, wherein up PUCCH only appears on SPcell.Generally speaking, in order to ensure correct subscriber equipment (UE) behavior, UE and base station (eNB) must be synchronous on relevant uplink/downlink configuration parameter.Such as, eNB is by the multiple parameter of transmission configuration for autonomous ascending control information, such as resource indicates, transmission cycle etc.For the transmission of these autonomous ascending control informations, when UE and eNB must start uplink to be reached synchronously at UE in what resource, thus makes eNB can not miss any uplink of UE.When adopted in UE side this is at new configuration parameter with eNB and UE is synchronously identical.
According to current process, following several SCG configuration/reconfiguration scene is had to need synchronous SeNB and UE in the use of configuration/reconfiguration parameter:
Scene 1: for SeNB adds a new Scell, it belongs to a new sTAG;
Scene 2: for SeNB adds a new Scell, it belongs to an existing sTAG;
Scene 3:SPcell changes, and new SPcell is the common Scell of a preexist;
Scene 4:SPcell changes, and new SPcell is a Scell newly added, and it belongs to an existing sTAG;
Scene 5:SPcell changes, and new SPcell is a Scell newly added, and it belongs to a new sTAG;
Scene 6:SPcell changes, and old SPcell becomes the Scell of a common activation, and its uplink synchronous still keeps after SPcell change procedure terminates;
Scene 7:SPcell changes, and old SPcell becomes the Scell of a common activation, but its uplink synchronous is invalid after SPcell change procedure terminates.
For scene 1,5 and 7, before UE transmits on corresponding Scell or new SPcell, first UE should pass through PRACH process implementation uplink synchronous, and that is, for scene 1,5 and 7, up PRACH process is compulsory.And for scene 2,3,4 and 6, due to UE uplink synchronous on the corresponding Scell or new SPcell, therefore for these scene PRACH not necessarily.
In the Pcell of R10, all newly/upgrade parameter, comprise the parameter of the transmission for autonomous ascending control information, all configured by RRC information.UE and eNB needs to reach synchronously in the parameter when UE adopts these new/renewals, such as, needs to reach in the transmission when UE carries out these ascending control informations in what resource synchronously, can be ready to receive these ascending control informations to make eNB.Such as, the transmission of ascending control information is carried out after a period of time after UE can reshuffle message sending RRC; In eNB side, after receiving RRC and having reshuffled message, eNB knows UE and will carry out the transmission of ascending control information over time, and is ready to receive these ascending control informations at corresponding time slot.
But for dual link scene, RRC agreement is only positioned at macro cell base station (MeNB) side.Such as, although SeNB will provide some parameters to be used for supporting that MeNB generates RRC information, the configuration of the transmission of ascending control information, SeNB does not know UE and when will complete relevant configuration/reconfiguration.Because RRC process occurs over just between MeNB and UE, therefore, SeNB does not know these new configuration parameters and will when come into force in UE side, and when also not exactly know UE thus will start to carry out the transmission of ascending control information.That is, based on the mechanism of R10, cannot ensure that SeNB and UE uses the configuration parameter of new/renewal (such as, in transmission time points and the relevant resource of ascending control information) upper synchronous at UE.Therefore, need new technical scheme to solve this problem, new configuration parameter can be known to make SeNB and when will use in UE side, thus make SeNB can not miss the transmission of the ascending control information of UE.
At present, a kind of existing scheme uses PRACH to solve this problem.That is, in order to UE and eNB synchronous in the use of the new configuration parameter of specific cell, need to carry out PRACH on this community.The time point that this specific cell completes this PRACH using by as the prompting of configuration parameter adopting new/renewal, such as, carries out the prompting of the transmission of ascending control information as UE.This existing scheme is feasible for scene 1,5 and 7, because always need to carry out PRACH for these scenes; And for scene 2,3,4 and 6, although for uplink synchronous without the need to up PRACH, PRACH process only synchronous UE and SeNB in the use at new configuration parameter of triggering redundancy of but having to, such as synchronous UE and SeNB in the autonomous uplink of UE.This overhead that will cause PRACH resource.
Summary of the invention
Therefore, be necessary to provide a kind of new technical scheme, its can in the new/use of configuration parameter that upgrades synchronous UE and eNB, and the PRACH process of redundancy can not be introduced.

Embodiment
Below with reference to accompanying drawing, each embodiment of the present invention is described in detail.
The object of the invention is to: synchronous UE and SeNB in the use of the configuration parameter of new/renewal.For ease of describing, hereinafter by the transmission carrying out autonomous ascending control information using UE as using as UE that these are new/example that the configuration parameter that upgrades is is described in detail four embodiments of the present invention, it will be understood by those skilled in the art that technical scheme of the present invention is not limited to use the new configuration parameter relevant to the transmission of ascending control information.
pRACH process on embodiment 1: one community triggers the transmission of the ascending control information on another community
The central scope of embodiment 1 is: make the PRACH process on a community (such as community 1) trigger the transmission of the autonomous ascending control information on another community (such as community 2).Therefore, the technical scheme of embodiment 1 does not need because SeNB wants the transmission of the ascending control information triggering UE on community 2 and carry out PRACH process on community 2.
Based on the technical scheme of embodiment 1, when UE complete its to the RRC configuration/reconfiguration of one or more communities of SeNB after, UE should suspend the transmission of its autonomous ascending control information on all these communities, until a PRACH process on arbitrary community of this SeNB is triggered and terminates.In other words, after a PRACH on arbitrary community of SeNB terminates, UE will start the transmission of autonomous ascending control information on the community of all RRC of completing configuration/reconfiguration, and no matter this PRACH carries out and completes on which community.Therefore, from the angle of UE, a PRACH on arbitrary community of SeNB carries out the transmission of autonomous ascending control information on the community of all RRC of completing configuration/reconfiguration by triggering UE.From the angle of SeNB, when receiving after RRC configuration/reconfiguration completes message from MeNB, SeNB knows UE and has completed relevant reshuffling, and the transmission of the ascending control information of UE on corresponding community is paused.Therefore, if PRACH is triggered, such as, for above-mentioned scene 1,5 or 7, so SeNB knows UE will start the transmission of its autonomous ascending control information on all communities that it completes RRC configuration/reconfiguration after this PRACH process terminates.So SeNB will be ready to receive these autonomous ascending control informations, and no matter PRACH carries out and completes on which community.Therefore, for EXAMPLE l, need the behavior defining new UE and SeNB.
The new behavior of UE:
After-RRC the configuration/reconfiguration that completes one or more communities of SeNB as UE, UE can not use relevant new configuration parameter at once, and as an alternative, UE will suspend the transmission of its autonomous ascending control information on all communities completing configuration/reconfiguration.
After-a PRACH on arbitrary community of SeNB is successfully completed, the transmission that UE will bring into use relevant new configuration parameter to carry out autonomous ascending control information on all communities that it completes RRC configuration/reconfiguration.
The new behavior of SeNB:
-after the SeNB RRC configuration/reconfiguration received from MeNB corresponding to one or more communities of this SeNB completes message, SeNB knows UE and to have completed the RRC configuration/reconfiguration of this one or more community and UE has suspended the behavior of the autonomous uplink on all communities completing RRC configuration/reconfiguration.
After-a PRACH on arbitrary community of SeNB terminates, SeNB knows UE and the new configuration parameter of employing is started autonomous uplink on the community of all RRC of completing configuration/reconfiguration, so, the RRC configuration/reconfiguration that SeNB will be ready to receive at it completes the autonomous ascending control information one or more communities corresponding to message receiving UE, or SeNB is sent to all autonomous ascending control informations needing the community of configuration/reconfiguration receives UE included in the configuration/reconfiguration request of MeNB at it.
-those communities that RRC configuration/reconfiguration completes message are not received for SeNB, SeNB then thinks that UE not yet completes the RRC configuration/reconfiguration to these communities, therefore UE also can not carry out autonomous uplink on these communities, even if having PRACH to complete on arbitrary community of this SeNB.
As can be seen here, the technical scheme of embodiment 1, without the need to carrying out extra PRACH with SeNB and UE synchronous in the use of new configuration parameter on each community, therefore, can reduce the situation of PRACH g-load.Although embodiment 1 still needs PRACH to transmit, its dependence of PRACH compared with existing program reduces greatly.
Such as, for above-mentioned scene 6, in the process that SPcell changes, previous SPcell (such as community 1) becomes common Scell, and the common Scell (such as community 2) previously existed becomes new SPcell.Suppose after the change of SPcell terminates, the uplink sync status on community 1 and community 2 will keep.So, after the change of SPcell terminates, UE can not carry out the transmission of any ascending control information on community 1 and community 2, even if the uplink sync status on this Liang Ge community is still effective.In order to trigger the autonomous up behavior of the UE on this Liang Ge community, SeNB has to trigger the PRACH on arbitrary community of this Liang Ge community.After this PRACH process terminates, UE will restart the transmission of ascending control information on community 1 and community 2 based on new configuration parameter.In SeNB side, after the PRACH of this redundancy completes, SeNB knows UE and will start to carry out the transmission of ascending control information on this Liang Ge community, and is ready to receive this ascending control information.Therefore, compared to existing scheme, embodiment 1 only needs the PRACH process of a redundancy, therefore effectively can alleviate the situation of PRACH g-load.In addition, if having a new community 3 to add SeNB to and it belongs to new sTAG, so SeNB has to the PRACH that triggered before UE carries out uplink on this community 3.For this situation, embodiment 1 no longer needs any extra PRACH process to restart the uplink on community 1 and community 2, and as an alternative, the enforceable PRACH process on community 3 is by the uplink of triggering UE on community 1 and community 2.
embodiment 2: define new MACCE for controlling the transmission of autonomous ascending control information
For embodiment 2, propose a kind of new MACCE for when adopting synchronous UE and SeNB on new configuration parameter.If SeNB wants to trigger UE adopt new configuration parameter, SeNB is used to indicate UE adopts new configuration parameter by issuing a new MACCE.That is, in example 2, newly-designed MACCE is used to substitute PRACH process with UE and SeNB synchronous in the use of new configuration parameter.Therefore, compared to existing program, the cost of embodiment 2 is less.Particularly, new MACCE is designed by following two kinds of modes.
Mode 1: one MACCE triggers UE and adopt new configuration parameter on all community that it completes configuration/reconfiguration.
Mode 2: one MACCE only trigger UE on cell portion, adopt new configuration parameter.
For mode 1, after receiving new MACCE, UE starts to carry out autonomous uplink by all communities that it completes configuration/reconfiguration.In SeNB side, after having issued this new MACCE, SeNB should be ready to receive the autonomous uplink of UE at it from the RRC configuration/reconfiguration that MeNB the receives one or more communities completed corresponding to message, or SeNB is sent to all autonomous uplink needing the community of configuration/reconfiguration receives UE included in the configuration/reconfiguration request of MeNB at it.Therefore, the mode 1 of embodiment 2 is similar to embodiment 1, and its difference is to use MACCE to replace PRACH process as triggering.For mode 1, as shown in Figure 1, only comprise the sub-head of MACCE in new MACCE, and do not comprise MACCE payload segment.The sub-head of MACCE only comprises byte a: R/R/E/LCID, one of them new LCID is used to indicate this MACCE to be a new MACCE to UE, and it is used to indicate the transmission that UE carries out ascending control information on all communities that it completes RRC configuration/reconfiguration.As can be seen here, in mode 1, only have a byte to be used to synchronous UE and SeNB in the use of new configuration parameter, this is very favorable compared to existing program.
UE is only triggered for mode 2, SeNB on the community indicated by the community indication information of MACCE, adopts new configuration parameter.As shown in Figure 2, the MACCE of mode 2 comprises the sub-head of MACCE and MACCE payload segment, wherein MAC head comprises indication information, be used to indicate UE to communicate based on new configuration parameter, the load of MACCE comprises community indication information, is used to indicate and needs UE to carry out the community communicated thereon based on new configuration parameter.Such as, a byte can be used in the load of MACCE can to start its uplink on which or which community to indicate UE.According to relevant SGell index information, the community of a configuration of each bit instruction SeNB in MACCE load.Such as, if Ci=1, so UE uses new configuration parameter to carry out uplink by the community corresponding to Scell index information and Ci.Further, UE should ignore in this byte the bit being set to 0.Certainly, also can represent that instruction UE uses new configuration parameter to carry out upper line parameter with " 0 ", in this case, the bit being set to 1 in this byte should be left in the basket.
For SeNB, mode 2 only be sure of that the situation that RRC configuration/reconfiguration completes on cell portion is favourable.Such as, SeNB has been configured 3 communities: community 1, community 2 and community 3, but due to such as X2 transmission delay, the RRC that SeNB only receives on community 1 and community 2 from MeNB completes message, and the RRC on community 3 completes message does not receive.Therefore, SeNB only requires that UE adopts new configuration parameter to carry out uplink on community 1 and community 2, and SeNB is before requiring that UE carries out uplink on community 3, has to continue to wait for that the RRC on community 3 completes message.The benefit of the mode 2 of embodiment 2 is its flexibility, and SeNB can indicate UE to carry out uplink easily on any community that configuration/reconfiguration completes.
embodiment 3: redefine the transmission of activation/deactivation MACCE for the autonomous ascending control information of control UE
As above discuss, the technical scheme of embodiment 2 very has flexibility, only need the data load of a byte or two bytes just can realize synchronous UE and SeNB in the use of new configuration parameter, but it needs to define new MACCE extraly.Embodiment 3 then reuses the MACCE of current activation/deactivation to realize this object.To this, need to define new UE behavior:
-principle 1: when completing the RRC configuration/reconfiguration on SPCell for UE, UE should check in activation/deactivation MACCE the bit indicating SPcell.For this situation, need the bit redefining instruction SPcell new configuration parameter whether should be adopted on this SPcell to start its autonomous uplink for instruction UE.Such as, if this bit is 1, then indicate UE that new configuration parameter should be adopted on SPcell to carry out uplink; If this bit is 0, then UE instruction should continue to suspend its up behavior on SPcell, because SeNB does not still be sure of whether UE has completed the RRC configuration/reconfiguration on SPcell.Certainly, also can use " 0 " to represent instruction UE on SPcell, adopt new configuration parameter to carry out uplink; Instruction UE continues to suspend its up behavior on SPcell to use " 1 " to represent.Therefore, can see, for this situation, the bit of instruction SPcell has been endowed New function.And for other situations, owing to not having RRC configuration/reconfiguration on SPcell, therefore UE should ignore this bit of instruction SPcell, because SPcell is always in state of activation.
-principle 2: common Scell UE being completed to RRC configuration/reconfiguration thereon, if indicate the bit of this Scell to be 1, then represents and activates this Scell, also indicates UE that new configuration parameter should be adopted on this Scell to carry out autonomous uplink simultaneously; If indicate the bit of this Scell to be 0, then represent deexcitation this Scell, also indicate simultaneously UE should upper once activate this Scell time, this Scell adopts new configuration parameter to carry out autonomous uplink.And UE is not carried out to those Scell of RRC configuration/reconfiguration to it, indicate the bit of this Scell still as a common activation/deactivation instruction.
Therefore, for embodiment 3, current activation/deactivation MACCE can be reused, but need definition new UE behavior as above.The present embodiment will cause a little complicated UE behavior, particularly for the operation of SPcell.UE must clearly know the bit that when should check instruction SPcell and the bit when should ignoring instruction SPcell according to different situations.In addition, should distinguish to reshuffle for common Scell, UE and whether occur.If reshuffled, then UE checks that relevant bit determines whether adopt new configuration parameter and restart uplink; If reshuffled Scell, so this MACCE is still a common activation/deactivation MACCE.Such as, if bit is 1, then the ongoing up behavior on this Scell can not be affected.
Embodiment 4: the transmission being triggered ascending control information by dispatching command
For embodiment 4, the dispatching command carrying out uplink/downlink transfer of data on specific cell is indicated to be used to trigger transmission UE Lai Gai community being carried out autonomous ascending control information.According to embodiment 4, when receiving after RRC completes message from MeNB, SeNB knows the transmission that UE is just suspending the autonomous ascending control information on specific cell.Then, SeNB issues dispatching command with the uplink/downlink transfer of data of scheduling on this community.In UE side, after terminating the RRC configuration/reconfiguration process of this community, UE will suspend the uplink on this community.After this, if the dispatching command of the uplink/downlink transfer of data of instruction on this community is received, then UE will adopt new configuration parameter to start the transmission of its autonomous ascending control information on this community.Because dispatching command always needs for transfer of data, therefore, embodiment 4 is feasible schemes.
Be understandable that, as embodiment 2, embodiment 4 also realizes by two kinds of modes.The dispatching command that mode 1:SeNB is sent to UE is used to indicate UE and communicates based on new configuration parameter on the community of all RRC of completing configuration/reconfiguration, correspondingly, based on new configuration parameter on SeNB is then ready to complete corresponding to message in the RRC configuration/reconfiguration received from MeNB one or more communities, communicate with UE, or to be sent in the configuration/reconfiguration request of MeNB included all to need on the community of configuration/reconfiguration at it, based on new configuration parameter, to communicate with UE.The dispatching command that mode 2:SeNB is sent to UE is used to indicate on the community corresponding to the Resource Block of UE in this dispatching command and communicates based on new configuration parameter, correspondingly, SeNB to be then ready on the community corresponding to the Resource Block in this dispatching command, based on new configuration parameter, communicate with UE.
It should be noted that, above-described embodiment is only exemplary, but not limitation of the present invention.Any technical scheme not deviating from spirit of the present invention all should fall within protection scope of the present invention, and this comprises the different technologies feature that use occurs in different embodiments, and installation method can combine, to obtain beneficial effect.In addition, any Reference numeral in claim should be considered as the claim involved by restriction; " comprise " word and do not get rid of device unlisted in other claims or specification or step.Technical scheme of the present invention can pass through software, and the mode of hardware or software and hardware combining realizes.
