Embodiment

Hereinafter with reference to the some exemplary embodiments shown in accompanying drawing, principle of the present invention and spirit are described.Should be appreciated that describing these embodiments is only used to enable those skilled in the art to understand better and realize the present invention, and not limit the scope of the invention by any way.

Due to the problem that embodiments of the invention are the On/Off of small-cell and dual link system how coordinated manipulation for one of problem of solving.Due in the technology of enhancement mode small-cell, small-cell for Inter-Cell Interference Coordination and may be avoided, load balancing/object such as transfer and conserve energy and be unlocked adaptively or close.Again due in dual link system, special auxiliary community is configured to have the function of such as PUCCH transmission, and its status is different from other auxiliary community, and it can not be activated and deexcitation.So, when the On/Off function of small-cell uses together with dual link system, if specify that special auxiliary community can be closed, then can there is many problems when closing special auxiliary community, one of object of embodiments of the invention is just clear and definite or clarifies in dual link system for closing the concrete operation step of auxiliary community.

According to a first aspect of the invention, the special auxiliary community in the auxiliary cell set of dual link system allows to be closed or to open, closedown or the unlatching of special auxiliary community can be triggered by prothetic group station.

Particularly, it will be appreciated by those skilled in the art that, closedown or the unlatching of special auxiliary community may be triggered in prothetic group station under the condition considering many factors, such as in order to load minimizing, load balancing, interference coordination, interference are avoided, saved energy etc. reason.Those skilled in the art also will understand, and prothetic group station also may according to other closedown or unlatching because usually triggering special auxiliary community.

Due in dual link system, subscriber equipment (UE) can be configured the carrier wave had in prothetic group station, also may be configured the multiple carrier waves had in prothetic group station.In both cases, after the closedown of the special auxiliary community of auxiliary base station triggers, the required operation performed is not identical.

According to one embodiment of present invention, when subscriber equipment is only configured the carrier wave had in prothetic group station, prothetic group can carry out following three kinds of operations accordingly after standing in the closedown triggering special auxiliary community.

A the transmission between subscriber equipment and prothetic group station can be suspended in () prothetic group station, the corresponding signaling diagram of this situation is shown in Figure 1.In this operation, prothetic group station just can send the shutdown command of special auxiliary community to dominant base, dominant base can will be closed the special auxiliary community of notifying user equipment, and such as, by RRC signaling, such as RRC connects reconfiguration message and sends the pent information in special auxiliary community.The RRC signaling used above those skilled in the art will appreciate that is only a kind of example, and dominant base can also carry out notifying user equipment by other message means.

If the closedown of special auxiliary community is because load reduces or interference, then data may be also had when the transmission between subscriber equipment and prothetic group station is suspended to need to send subscriber equipment to by prothetic group station.

In this case, if the radio bearer of dual link system (RB) type is the carrying of auxiliary cell set, then should perform auxiliary cell set modification process, wireless radio bearer type to be changed into the carrying of main plot group from the carrying of auxiliary cell set.So, need the data being sent to subscriber equipment by prothetic group station can be transmitted by dominant base, the signaling diagram of this solution shows in fig 2.

The flow control function now in dominant base if radio bearer type is segmentation carrying, then do not need the amendment carrying out radio bearer, because can control not make data by auxiliary base-station transmission for this segmentation carrying.

If do not have data to need to send subscriber equipment to by prothetic group station when the transmission between subscriber equipment and prothetic group station is suspended, then do not need the amendment performing bearer types yet.

B () sends special auxiliary community by pent message to dominant base, so that dominant base determines whether add Xin Fu community thus complete special auxiliary cell change, the signaling diagram of this operation correspondence is shown in Figure 3.In this operation, because special auxiliary community will be closed, so prothetic group station can perform the change of special auxiliary community.Current, reach in dual link system and decided through consultation as follows: decided the special auxiliary community in auxiliary cell set by prothetic group station; Auxiliary cell set modification process can be used to change the special auxiliary community in auxiliary community.But due in the present embodiment, subscriber equipment is only configured the carrier wave had in prothetic group station.So do not have other auxiliary community can change as special auxiliary community.

In this case, to dominant base, prothetic group station can notify that special auxiliary community is by pent and need reformed state, triggers the interpolation to auxiliary community thus.Dominant base can determine whether interpolation one Ge Fu community.

If dominant base is determined to add auxiliary community, request is added in response to the auxiliary community receiving dominant base transmission in prothetic group station, adds Xin Fu community; And perform the change of special auxiliary community, to be closed order by dominant base to the subscriber equipment special auxiliary Cell Change Order of transmission and/or old special auxiliary community.

If dominant base is determined not add auxiliary community, then prothetic group station is suspended the transmission between subscriber equipment and prothetic group station or is discharged the connection at prothetic group station.

C the connection discharging prothetic group station is determined at () prothetic group station, the corresponding signaling diagram of this operation is shown in Figure 4.In this case, prothetic group station sends the request of the connection at release prothetic group station to dominant base; Or prothetic group station sends special auxiliary community shutdown command, so that described dominant base sends the order of the connection discharging described prothetic group station to described user to described dominant base.

According to another embodiment of the invention, when subscriber equipment is configured to have the multiple carrier wave in prothetic group station, prothetic group can carry out following two kinds of operations accordingly after standing in the closedown triggering special auxiliary community.

If a () has other auxiliary communities to be suitable as special auxiliary community, then prothetic group station performs the change of special auxiliary community, and the corresponding signaling diagram of this operation is shown in Figure 5.Due in the present embodiment, subscriber equipment is configured the multiple carrier waves had in prothetic group station, when so current special auxiliary community is closed, prothetic group station can select a suitable auxiliary community as new special auxiliary community in other auxiliary community, then carries out the change process of auxiliary community.

If b () does not have other auxiliary communities to be suitable as special auxiliary community, then prothetic group station sends the message of will close special auxiliary community to dominant base, so that dominant base is determined to add Xin Fu community as special auxiliary community, the corresponding signaling diagram of this operation is shown in Figure 6.In this case, do not have other auxiliary communities to be suitable as reason that special auxiliary community may be the load due to such as PUCCH.Those skilled in the art will appreciate that also may because other reason causes not having other auxiliary communities to be suitable as special auxiliary community.In this case, dominant base can be asked prothetic group station to add Xin Fu community and is used as special auxiliary community.

In the present embodiment, what special auxiliary community was closed can carry out notifying user equipment by RRC signaling.But those skilled in the art will appreciate that the present invention is not limited to this, notifying user equipment can also be carried out by other message signaling.Or in the present embodiment, after special auxiliary cell change, special auxiliary community before has become common auxiliary community, then its closedown can have been performed by the activation in such as carrier aggregation and deexcitation MAC order.

In addition, in the present embodiment, because the auxiliary community that there are other can be served for UE, so radio bearer type does not need amendment.

According to another embodiment of the invention, the special auxiliary community in the auxiliary cell set of dual link system allows to be closed or to open, can be triggered the unlatching of special auxiliary community by prothetic group station, the corresponding signaling diagram of this operation is shown in Figure 10.

After prothetic group stands in the unlatching triggering special auxiliary community, auxiliary community can send the information of the special auxiliary community of unlatching, so that the special auxiliary community of dominant base notifying user equipment will be unlocked to dominant base.In this case, dominant base can carry out by RRC signaling the information that notifying user equipment will be unlocked about special auxiliary community.But those skilled in the art will appreciate that and the present invention is not limited thereto, other information order can also be used to carry out notifying user equipment.

According to a second aspect of the invention, the special auxiliary community in the auxiliary cell set of dual link system allows to be closed or to open, closedown or the unlatching of special auxiliary community can be triggered by dominant base.

Particularly, it will be appreciated by those skilled in the art that, dominant base may trigger closedown or the unlatching of special auxiliary community under the condition considering many factors, such as in order to load minimizing, load balancing, interference coordination, interference are avoided, saved energy etc. reason.Those skilled in the art also will understand, and dominant base also may according to other closedown or unlatching because usually triggering special auxiliary community.

Due in dual link system, subscriber equipment (UE) can be configured the carrier wave had in prothetic group station, also may be configured the multiple carrier waves had in prothetic group station.In both cases, the operation of dominant base required execution after triggering the closedown of special auxiliary community is not identical.

According to one embodiment of present invention, when subscriber equipment is only configured the carrier wave had in prothetic group station, dominant base can carry out following corresponding operation after the closedown triggering special auxiliary community.

A () dominant base sends special auxiliary community turn-off request and adds Xin Fu community for user to prothetic group station, if prothetic group station accepts the special auxiliary community turn-off request that dominant base sends, and the change of the special auxiliary community of execution, prothetic group station.In this case, special auxiliary cell change can be the auxiliary community of the determined new interpolation of dominant base by prothetic group station, and then closes previous special auxiliary community.The corresponding signaling diagram of this operation is shown in Figure 7.

If b () dominant base cannot add Xin Fu community for user, then dominant base only sends special auxiliary community turn-off request to prothetic group station, if prothetic group station accepts the special auxiliary community turn-off request that described dominant base sends, auxiliary community is suspended the transmission between subscriber equipment and prothetic group station or is discharged the connection at prothetic group station.In this case, prothetic group stand in receive that dominant base sends send special auxiliary community turn-off request after, can send particular cell shutdown command to dominant base and suspend the transmission by prothetic group station, signaling diagrams of this kind of these operations of situation are shown in Figure 8.

If the connection discharging prothetic group station is determined at prothetic group station, then dominant base receives the request at release prothetic group station from prothetic group station; The signaling diagram of this kind of situation is shown in Figure 9.Or dominant base receives special auxiliary community shutdown command in response to from prothetic group station, send the order at release prothetic group station to user.

If prothetic group station does not accept the special auxiliary community turn-off request that dominant base sends, dominant base will receive the special auxiliary community turn-off request acknowledge message of prothetic group station transmission, i.e. refuse information.

According to another embodiment of the invention, when subscriber equipment is configured to have the multiple carrier wave in prothetic group station, dominant base can carry out following corresponding operation after the closedown triggering special auxiliary community.

Dominant base sends special auxiliary community turn-off request to prothetic group station, if prothetic group station accepts the special auxiliary community turn-off request that dominant base sends, prothetic group is stood erectly to connect and performed special auxiliary cell change; In the present embodiment, because subscriber equipment is configured multiple carrier waves of having in prothetic group station, so when special auxiliary community is closed, if there is suitable auxiliary community as special auxiliary community, prothetic group station can directly select suitable auxiliary community as new special auxiliary community from remaining auxiliary community.

If prothetic group station does not have suitable community to be suitable as new special auxiliary community, then prothetic group station sends the interpolation request of prothetic group station to dominant base, and dominant base adds request in response to receiving auxiliary community from prothetic group station, determines whether to add auxiliary community.

If dominant base can not add auxiliary community, then dominant base notice prothetic group station, so that prothetic group station is suspended the transmission between subscriber equipment and prothetic group station or is discharged the connection at prothetic group station.

Or

Dominant base sends special auxiliary community turn-off request to prothetic group station and request is added in auxiliary community, if prothetic group station accepts the special auxiliary community turn-off request that dominant base sends, prothetic group station performs the change that confirmation and special auxiliary community are added in auxiliary community, is new auxiliary community of adding by special auxiliary cell change; In this case, dominant base can send Xin Fu community directly to prothetic group station and add request while sending special auxiliary community turn-off request to prothetic group station, prothetic group can add Xin Fu community as special auxiliary community after standing in and receiving this request, and the auxiliary community before need not selecting is used as special auxiliary community.

According to another embodiment of the invention, the special auxiliary community in the auxiliary cell set of dual link system allows to be closed or to open, can be triggered the unlatching of special auxiliary community by dominant base, the corresponding signaling diagram of this operation is shown in Figure 11.

After dominant base triggers the unlatching of special auxiliary community, dominant base can send the request of opening special auxiliary community to prothetic group station, so that prothetic group station determines whether open special auxiliary community.

If prothetic group station determines to open special auxiliary community, then prothetic group station sends the information of the special auxiliary community of unlatching to dominant base, and in response to the information received opening special auxiliary community from prothetic group station, the special auxiliary community of dominant base notifying user equipment will be unlocked.

According to one embodiment of present invention, to be triggered by prothetic group station or dominant base in the embodiment of closing special auxiliary community above-mentioned, configuration is measured for RRM, two kinds of selections can be had.A kind of selection is, no matter be all configured with the measurement based on finding reference signal (DRS) when opening in small-cell or close; Alternatively, be just configured based on when finding that the measurement of reference signal is only closed in small-cell.Therefore, according to the present embodiment of the present invention, if based on when finding that the measurement Jin Fu community of reference signal is configured when closing, when special auxiliary community is closed, dominant base also should send about reshuffling of measuring in the RRC connection that the closedown for special auxiliary community is correlated with is reshuffled.

In addition, about dual link system, RAN2 has decided through consultation that special auxiliary community is decided at prothetic group station, and dominant base Jin Fu community is added or just provided measurement result when setting up.But, in an embodiment of the present invention, for the change process of special auxiliary community, still need this measurement.

According to one embodiment of present invention, three kinds are provided for providing the selection of measurement result.The first selection does not change existing rule to obtain the measurement for dual link, and namely dominant base Jin Fu community is added or provided measurement result when setting up.The second is selected, and dominant base sends measurement result to prothetic group station termly, or sends other information being used for small-cell On/Off and determining, such as load state information etc. simultaneously.The third selection is that auxiliary base station requests dominant base sends measurement result.

In addition, according to one embodiment of present invention, in each embodiment described above, prothetic group station until send special auxiliary community and close/open related command and obtain the acknowledge message from subscriber equipment, then can perform the closedown/unlatching of corresponding auxiliary community; Or prothetic group station while related command is closed/opened in the special auxiliary community of transmission, can perform the closedown/unlatching of corresponding auxiliary community.
