Description
Technical field
The present invention relates to the dual link system in communication network, more specifically, relate in dual link system, control particular cell method and device.
Background technology
According to the current state of dual link system, the critical function of particular cell (SPcell) supports to transmit from the uplink and downlink of base station.In dual link system, subscriber equipment can be connected with macro base station (MeNB) and from base station (SeNB) simultaneously, macro base station and carry out independent resource scheduling from base station in the community administered separately.Although be in from the particular cell of base station the preliminary agreement that permanent activation state has obtained 3GPP within its useful life cycle, the permanent activation state of particular cell has also suffered the query of multiple company.Three potential scenes are had at least to need to suspend the transmission of particular cell at present:
Scene one: for UP3C scheme, comprising particular cell from all communities of base station should be all normal cell for defining such as R11.Such as when buffer data size is less, macro base station can meet the requirement of up-downgoing business data transmission, there is no need the business datum allowed from base station bypass macro base station, therefore in order to avoid the power dissipation of subscriber equipment also there is no need to allow the community from base station be in state of activation.
Scene two: for UP1A scheme, the particular cell of subscriber equipment temporarily may be in bad situation.This can pass through macro base station (according to RRM measurement report or RLM report) or detect from base station (based on CQI).For this situation, if the upward signal of particular cell still transmits continuously, interference may be produced to other subscriber equipmenies.In order to avoid this interference, if do not perform deactivating operation, the configuration that radio resource controller (RRC) reconfigures to cancel configured community or cancel ascending physical signal control channel (PUCCH) resource can only be passed through, to eliminate uplink interference.It should be noted that because subscriber equipment only and between macro base station has RRC to connect, macro base station and will extra x2 delay be produced from the communication between base station.In addition, if the channel quality of particular cell takes a turn for the better at short notice, this operation cancelling configuration can't bring benefit.
Scene three: although RANl to the concept of restarting/closing of community still under discussion, probably this concept will be combined with dual link concept.That is, when macro base station temporary close is from base station, all communities from base station comprise particular cell, also should be closed rapidly.
Based on above-mentioned three kinds of scenes, although 3GPP has tentatively agreed to that particular cell should be in permanent activation state, still has strong requirement to cancel the permanent activation state of particular cell.The temporary transient upward signal of stopping particular cell and/or the simplest and the most direct method of downstream signal are the changing process performing particular cell, thus make ascending physical signal control channel be relocated to another from the community of base station, and current particular cell becomes normal cell.Deactivating operation can be carried out for this normal cell like this by from base station by MAc control unit signaling.This simple and direct method has at least and comprises following shortcoming:
If 1. suspend the upward signal of particular cell and/or downstream signal by from base station triggers, due to the time delay of RRC process and X2 interface, longer time delay can be produced;
2. unnecessary particular cell reconfigures and can cause unnecessary signaling consumption;
3., when only having a community from base station, that has no idea to realize particular cell reconfigures process.So in this case, above-mentioned simple and direct method is infeasible;
4。Even if existing particular cell may become normal cell to perform activation or deactivating operation, a new particular cell also can be produced.Therefore, for above-mentioned scene one and scene three, the upward signal of new particular cell and/or the activation of downstream signal or deactivating operation still can not be controlled rapidly.
The present invention, for above-mentioned three kinds of scenes, proposes and fast suspends the uplink communication of particular cell and the solution of downlink communication, with the power consumption of saving subscriber equipment or the interference avoiding other subscriber equipmenies.

Embodiment
In the specific descriptions of following preferred embodiment, with reference to the accompanying drawing formed appended by a part of the present invention.Appended accompanying drawing shows by way of example and can realize specific embodiment of the present invention.The embodiment of example is not intended to limit according to all embodiments of the present invention.Be appreciated that under the prerequisite not departing from scope of the present invention, other embodiments can be utilized, also can carry out amendment that is structural or logicality.Therefore, following specific descriptions are also nonrestrictive, and scope of the present invention limited by appended claim.It should be noted that, although describe the step of method in the present invention in accompanying drawing with particular order, but this not requires or hint must perform these operations according to this particular order, or the operation shown in must performing all could realize the result of expectation, on the contrary, step described herein can change execution sequence.Additionally or alternatively, some step can be omitted, multiple step be merged into a step and perform, and/or a step be decomposed the multiple step of dimension and perform.
Be directed to scene two mentioned above in the present invention, when the wireless channel of particular cell temporary transient poor time, in order to avoid causing uplink interference to other subscriber equipmenies, wishing from base station can deexcitation particular cell.But, if fully deexcitation particular cell, namely deexcitation uplink communication and downlink communication is comprised, the community from base station is again activated from base station by transmission MAC Control Element signaling of having no chance, its reason is the downlink physical control channel (PDCCH) that subscriber equipment has stopped detecting particular cell, so subscriber equipment receives the MAC Control Element signaling come from from base station again by having no chance.Therefore, the present invention proposes the uplink communication of only deexcitation particular cell and retains the downlink communication of particular cell, its objective is to ensure that subscriber equipment can accept downlink command with the uplink communication recovering particular cell and other community activated from base station.
Fig. 1 shows the schematic diagram of the MAC Control Element come from from base station.For activate or deexcitation MAC Control Element in, each community configured from base station corresponds to a bit MAC Control Element.That is, in MAC Control Element, there is the bit corresponding to particular cell.According to current agreement, particular cell is in state of activation all the time, so theoretically, the bit of particular cell can be counted as reserved bit, and subscriber equipment can ignore this bit usually.The position of the bit of the particular cell in MAC control signal determines according to the cell index information of particular cell.The cell index of described particular cell is by informing macro base station from base station assigns, and macro base station sends to subscriber equipment by RRC control signal.The cell index of described particular cell also can be systemic presupposition.As shown in Figure 1, each bit in MAC Control Element represents the activation of community or the designator of deexcitation that configure from base station, wherein C2, (also namely cell index value is 2), represent the activation of particular cell or the designator of deexcitation, C0, C1 and C3 mono-C7 representative from the activation of other community of base station or the designator of deexcitation.Activation or the position of deexcitation designator C2 in MAC Control Element of particular cell are determined by cell index.
Fig. 2 shows based on coming from the flow chart operated from the activation/deactivation of the MAC Control Element signaling of base station, and step as shown in Figure 2 will be described in more detail below.
In step 20l, in order to avoid causing uplink interference to other subscriber equipmenies, determining deexcitation particular cell from base station, setting the activation of other community or the designator of deexcitation from base station according to the corresponding situation in other community simultaneously.As schemed shown in l, such as indicate deactivating operation during C2=0, C2=1 indicates activation manipulation.The designator of other community also can be determined according to corresponding rule.
In step 202., send to subscriber equipment MAC Control Element signaling as shown in Figure 1 from base station and comprise for particular cell with for the activation of other community or deexcitation designator.Also can activate or deexcitation designator to user device transmissions any suitable downlink signaling from base station.
In step 203, subscriber equipment performs deactivating operation according to the designator of the designator of the described particular cell received and other community or performs activation manipulation.
As the C2=O received, subscriber equipment suspends for particular cell transmission uplink communication and the downlink communication continued for particular cell.Subscriber equipment suspends for the uplink communication of other community and downlink communication, and also namely as C2=0, the designator of other community ignored by subscriber equipment;
As the C2=l received, subscriber equipment recovers the uplink communication for particular cell.Subscriber equipment performs deactivating operation or execution activation manipulation according to the designator of other community in MAC Control Element signaling for other community:
A) when the designator instruction deactivating operation of other community, subscriber equipment continues to suspend the uplink communication for other community and downlink communication;
B) when the designator instruction activation manipulation of other community, subscriber equipment recovers for the uplink communication of other community and downlink communication.
Be directed to scene one mentioned above in the present invention and scene three, according to current agreement, preliminary decision does not have across the activation between base station or deactivating operation.This means, the MAC Control Element signaling of macro base station can not activate or deexcitation from the community of base station, also can not activate or the community of deexcitation macro base station from the MAC Control Element signaling of base station.The preliminary decision of this agreement at least comprises following two intentions:
One is intended that in order to avoid the turnaround time time delay on X2 interface.Such as, if to ask from base station macro base station by the MAC of macro base station control letter unit activate or deexcitation from the community of base station, first should send request to macro base station from base station, then macro base station produces MAC control signal, and sends to subscriber equipment.Then, macro base station also needs produced MAC control signal to send to from base station.Know that from base station community that it configures is activated or deexcitation accordingly, so from the subscriber equipment of stopping dispatching cell, base station.Find out thus, at least need the turnaround time of two X2 interface;
Another is intended that the community making macro base station and manage oneself from base station separately independently, comprises independently cell index and distributes.If allow macro base station to activate or deexcitation from the community of base station, just must ensure macro base station and from the conflict not having cell index between base station.Like this, just must coordinate at macro base station with from the cell index defining new complexity between base station in cell configuration process.
If macro base station intends to suspend all operations from base station really, the such as situation of scene one and scene three, just be necessary to define new solution, make macro base station can deexcitation from the community of base station time, avoid complicated cell index to coordinate simultaneously and reduce x2 time delay.Present invention further proposes two following solutions.
Fig. 3 shows another flow chart of particular cell activation/deactivation operation.Step as shown in Figure 3 will be described in more detail below.
In step 301, when buffer data size is less, macro base station can meet the requirement of up-downgoing business data transmission, there is no need the business datum allowed from base station bypass macro base station, and macro base station determines all communities of deexcitation from base station.If current particular cell is in deactivation status and buffer data size is comparatively large, macro base station determines to activate the community from base station.
In step 302, macro base station sends deexcitation or activation request to from base station, activation request instruction sends MAC layer control unit signaling from base station to subscriber equipment and makes subscriber equipment perform activation manipulation, and deexcitation request instruction sends MAC layer control unit signaling from base station to subscriber equipment and makes subscriber equipment perform deactivating operation.
In step 303, from base station according to the activation of the activation or deexcitation designator and other community that come from the activation of macro base station or deexcitation request setting particular cell or deexcitation designator.
In step 304, MAC Control Element signaling as shown in Figure 1, particular cell and the activation of other community or the designator of deexcitation is comprised to subscriber equipment transmission from base station.Also can activate or deexcitation designator to user device transmissions any suitable downlink signaling from base station.
In step 305, subscriber equipment performs deactivating operation according to the designator of the designator of the described particular cell received and other community or performs activation manipulation.
As the C2=0 received, subscriber equipment suspends the uplink communication for particular cell and the downlink communication continued for particular cell.Subscriber equipment suspends for the uplink communication of other community and downlink communication, and also namely as C2=0, the designator of other community ignored by subscriber equipment;
As the C2=1 received, subscriber equipment recovers the uplink communication for particular cell.Subscriber equipment performs deactivating operation or execution activation manipulation according to the designator of other community in MAC Control Element signaling to other community:
A) when the designator instruction deactivating operation of other community, subscriber equipment continues to suspend the uplink communication for other communities and downlink communication;
B) when the designator instruction activation manipulation of other community, subscriber equipment recovers for the uplink communication of other communities and downlink communication.
The benefit of scheme is as shown in Figure 3 mutually compatible with current agreement, and also namely not across the activation between base station or deactivating operation, namely MAC CE control unit signaling sends by from base station.Its shortcoming is that the uplink communication of only particular cell is deactivated, and downlink communication still keeps state of activation, although there is no need to keep downlink communication in these scenes.Therefore, subscriber equipment effectively can not save power consumption.
The activation defined according to 3GPP R1O or the MAC Control Element of deexcitation, as shown in Figure 4, its on the right side of first be reserved bit (R bit) position, R bit ignored usually by subscriber equipment.This is because " 000 " is always for the index of main plot (Primary Cell), and main plot is in permanent activation state.In 3GPP R12, in order to realize the object of macro base station deexcitation from the community of base station, suggestion redefines activation or the deactivating operation that R bit carrys out equipment for indicating user.As shown in Fig. 4, such as R bit=1 instruction activation manipulation, R bit=O indicates deactivating operation.
Fig. 5 shows another flow chart of particular cell activation or deactivating operation, and step as shown in Figure 5 will be described in more detail below.
In step 501, such as, in order to more save power, macro base station can temporary close from base station.In order to continue the business datum of bypass subscriber equipment, macro base station also can be restarted from base station.Thus, macro base station sets corresponding R bit value and performs activation manipulation or deactivating operation with equipment for indicating user.
In step 502, macro base station sends the designator of particular cell in the MAC Control Element signaling of macro base station as shown in Figure 4 to subscriber equipment, is also R bit.Macro base station also can activate or deexcitation designator to user device transmissions in any suitable downlink signaling.
In step 503, macro base station is activated or the instruction of deexcitation to sending from base station by X2 interface.Like this, can determine whether to recover or stop scheduling user's set according to the instruction of the activation received or deexcitation from base station.
In step 504, when receiving the instruction of the activation coming from macro base station from base station, from the MAc control unit signaling of base station, comprising the activation of other community or the designator of deexcitation to subscriber equipment transmission from base station.
In step 505, subscriber equipment performs deactivating operation according to the designator of the designator of the described particular cell received and other community or performs activation manipulation.
As the R=0 received, subscriber equipment performs deactivating operation.Subscriber equipment suspend for particular cell uplink communication and suspend for the downlink communication of particular cell.When the uplink communication of particular cell and downlink communication are suspended, subscriber equipment also suspends uplink communication for other community and downlink communication;
As the R=l received, subscriber equipment performs activation manipulation.Subscriber equipment recovers for the uplink communication of particular cell and downlink communication.Subscriber equipment performs deactivating operation or execution activation manipulation according to the designator come from from other community the MAC Control Element signaling of base station for other community:
A) when the designator instruction deactivating operation of other community, subscriber equipment continues to suspend the uplink communication for other communities and downlink communication;
B) when the designator instruction activation manipulation of other community, subscriber equipment recovers for the uplink communication of other communities and downlink communication.
Under normal circumstances, macro base station does not need to manage the operation from base station, so R bit value is always set to 1, such particular cell just remains at state of activation.This and the particular cell thought at present remain at state of activation and are consistent.On the other hand, if macro base station wants deexcitation from all communities of base station, the R bit value in the MAC Control Element of macro base station should be set to O and make the automatic deexcitation of subscriber equipment from all communities comprising particular cell of base station; If macro base station is wanted to allow from base station continue its business datum of bypass, macro base station can make subscriber equipment automatic activation for the uplink communication of particular cell and downlink communication by the MAC Control Element being 1 to the R bit value of subscriber equipment transmission macro base station.Macro base station is also to the notice sent from base station for the activation manipulation of particular cell.Then continue to activate from base station by its MAC Control Element signaling or deexcitation from other community of base station.
Obviously, macro base station can activate or deexcitation from the particular cell of base station, this and at present in 3GPP RAN2 not across base station between to activate or the agreement of deexcitation disagrees.But as mentioned above, there is the motivation of time-out subscriber equipment for the communication of particular cell in macro base station really.And, because only have a community (particular cell) to be managed by macro base station, therefore macro base station and the conflict from the cell index between base station also can be avoided.In addition, owing to can suspend the downlink communication of subscriber equipment for particular cell, the power also improving subscriber equipment saves efficiency.
To those skilled in the art, obviously the invention is not restricted to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present invention or essential characteristic, the present invention can be realized in other specific forms.Therefore, in any case, all should embodiment be regarded as exemplary, and be nonrestrictive.In addition, significantly, " comprising ' ' one word do not get rid of other elements and step, and wording " one ' ' do not get rid of plural number.Multiple elements of stating in device claim also can be realized by an element.First, second word such as grade is used for representing title, and does not represent any specific order.
