Description
Technical field
The present invention relates to wireless communication technology, relate in particular to method and device that the subscriber signal processing mode is coordinated.
Background technology
In cellular communication system, identical running time-frequency resource can be used in different sub-district, geographical position, to improve the service efficiency of frequency spectrum.In this case, two user's running time-frequency resources of different districts have to exist when overlapping and interfere with each other, and the user of the intersection of two or more sub-districts particularly interferes with each other more intensely, influences the throughput at cell boarder place.
Can adopt the coordination technique of minizone running time-frequency resource in the prior art, reduce interference.For example the time-frequency resource allocating of three sub-districts under NodeB can be coordinated by NodeB is unified, makes that between the resource that the user of different districts distributes be frequency division or time-division quadrature.
When the running time-frequency resource of the CU of different districts is non-orthogonal, promptly resource is overlapping, or overlapping is arranged, and NodeB can carry out the processing of multi-user association to these users, to reduce or to eliminate the interference between the user.For example, the interference cancellation techniques of serial.
The running time-frequency resource of distributing to the user comprises the resource of data channel and the resource that reference signal takies, and general reference signal is also referred to as pilot signal.At uplink direction, also to send corresponding reference signal usually in the time of the data of user's transmission, be used for receiving terminal and carry out channel estimating, so that carry out coherent demodulation, this reference signal is also referred to as the channel estimating reference signal.Also have a kind of up reference signal to be used for channel quality measurement in addition; Be used for measuring the channel quality on the frequency band of broad; Offer the base station and carry out multi-subscriber dispatching or user's modulation coding mode adjustment, this reference signal is called the channel quality measurement reference signal.
For the user's of different districts reference signal, complete when overlapping when its running time-frequency resource, can assign to distinguish through sign indicating number.For example, the sequence of using when reference signal can distribute the different time of same sequence to be shifted to different user when being similar to normal amplitude zero auto-correlation (CAZAC) sequence, utilizes the characteristic of sequence can obtain the sign indicating number branch quadrature of reference signal.In the prior art; Be specially, the sequence set for an identical reference signal of several cell allocation is used can be called the specific sequence set of cell set; A kind of special case is exactly the specific sequence set of NodeB, and promptly identical sequence set are adopted in three sub-districts under NodeB.To every kind of resource occupation mode of distributing to the signal of sequence modulation, there is a sequence corresponding in the sequence set.Because different districts has used identical sequence set; The running time-frequency resource that takies when the user's who is positioned at different districts reference signal is complete when overlapping; The sequence that they are selected for use is also identical, and through adopting the different sequences displacement, just obtaining completely between these signals, sign indicating number divides quadrature.
When but the running time-frequency resource that takies when two users' reference signal is identical, could use the orthogonalization method of the reference signal that this sign indicating number divides.When the running time-frequency resource that takies when two users' reference signal is overlapped, can't obtain a sign indicating number branch orthogonality.And different with data channel, when the running time-frequency resource that takies when two users' uplink reference signals is overlapped, there is not simple combination treatment method yet, reduce the interference between the uplink reference signals.In the prior art, a kind of way is to be the sequence set of a reference signal use of each cell allocation under the NodeB.Correlation is lower between the different sequences group, and interference ratio is more weak or more at random between the user's of therefore different sub-districts the uplink reference signals.But comparing with quadrature still has more intense interference.
For example, as shown in Figure 1, when user's reference signal and data time division multiplexing, reference signal can take identical frequency resource with data.And the resource allocation of user's data channel can be compared flexibly usually; Therefore, be easy to occur the situation that the running time-frequency resource of two CUs of different districts overlaps, at this moment; How the user is coordinated; To reduce restriction to scheduling of resource, improve performance simultaneously, reducing interference is the problem that needs solve.

Embodiment
Inventor of the present invention finds that the interference problem between the reference signal when overlapping for the running time-frequency resource of two CUs can not finely solve in the prior art, in order to alleviate interference, and flexibility that also can the limited subscriber scheduling of resource.
Like Fig. 2 embodiment of the invention coordination approach flow chart.Idiographic flow is following:
201, whether needs are coordinated according to the subscriber signal processing mode, confirm this subscriber signal processing mode;
202, indicate definite signal processing mode through the user oriented signaling to this user.
Wherein, the user oriented signaling of employing can be towards unique user or one group of user signaling.Such as signaling towards unique user, MAC (Medium Access Control, medium access control) signaling or RRC (Radio Resource Control, Radio Resource control) signaling, towards one group of user signaling, dynamic broadcasting is transmitted orders etc.
This coordination approach can be coordinated the user dynamically, reduces mutual interference.No matter the user's who coordinates running time-frequency resource is overlapping fully or overlap, can be suitable for.
Fig. 3 is the coordination approach flow chart of the embodiment of the invention based on reference signal.The coordination approach idiographic flow based on reference signal of the embodiment of the invention is:
301, confirm user's reference signal processing mode;
302, adopt this reference signal processing mode through user oriented signaling indication user.
Wherein, the user oriented signaling of employing can be for towards unique user or one group of user signaling.Such as signaling towards unique user, MAC signaling or RRC signaling.Employing reduces the suffered presence of intercell interference of reference signal based on the coordination approach of reference signal.Adopt this coordination approach, can dynamically indicate the user to carry out coordination based on reference signal.
In the coordination approach based on reference signal in the embodiment of the invention, two kinds are specially the reference signal of different resource occupancy mode with reference to signal, and a kind of reference signal is shown in Fig. 7 A, takies continuous subcarrier.A kind of in addition reference signal; Take discontinuous subcarrier; A kind of common discontinuous subcarrier mode is " pectination " subcarrier, and shown in Fig. 7 B, wherein grey one is " comb " sub-carrier set one; White one is " comb " to be the frequency division quadrature between the sub-carrier set two, two " comb ".For the user of two sub-districts, particularly be positioned at the boundary of two sub-districts, the user that need carry out the reference signal coordination, the user of sub-district 1 can take the subcarrier in the sub-carrier set one, the subcarrier in the CU sub-carrier set two of sub-district 2.And, can use the reference signal of continuous subcarrier for the user who does not coordinate.The user specifically is treated to according to what the resource of reference signal was carried out, carries out the emission or the reception of reference signal.
The pectination subcarrier that the reference signal of present embodiment takies can comprise 2 pectination sub-carrier set, can also comprise more a plurality of pectination sub-carrier set.For example, per 3 number of sub-carrier are got the sub-carrier set that 1 number of sub-carrier obtains, the pectination subcarrier that takies of signal as a reference, and then this pectination subcarrier can comprise 3 subcarrier set, can distribute to 3 users' collection.General, the R subcarrier set can be arranged, the interval of the corresponding subcarrier of R.R can fix, and also can be semi-static, or even dynamic.
When adopting above-mentioned two kinds to carry out universal time coordinated with reference to signal, the user that need not coordinate adopts the reference signal that takies continuous subcarrier; Need the user who coordinates to adopt the reference signal that takies the pectination subcarrier.
Concrete, the sequence of the reference signal modulation of different districts can be from the specific sequence set in sub-district.The specific sequence in the pairing sub-district of occupancy mode that has comprised various possible running time-frequency resources in the specific sequence set in sub-district.Therefore, the user when two sub-districts does not carry out universal time coordinated, and these users of assignment adopt the reference signal that takies continuous subcarrier; For example all be positioned at the inside of sub-district separately and since the different sequences group between interference ratio a little less than, perhaps interference ratio is more at random; It is albefaction; Therefore, between the user interference of reference signal also more weak, perhaps more at random.When the user's of different districts reference signal, carry out universal time coordinated, adopt the subcarrier that takies pectination owing to be frequency division, so the interference ratio of the reference signal between the user a little less than.
Except divide through customer location whether coordinate, can also divide through the resource that user's data takies and whether coordinate, for example, delimit one and be used for the resource that cell boundary users coordinate to be used.When the user used this piece running time-frequency resource to send data, its reference signal was just coordinated, and used the user of this running time-frequency resource to adopt the reference signal that takies the pectination subcarrier.Do not use the user of this running time-frequency resource then to adopt the reference signal that takies continuous subcarrier.This piece running time-frequency resource can pass through the RRC signaling, user's special RRC signaling for example, and perhaps the signaling of user oriented group such as Dynamic Broadcast Channel, indicates the user to adopt which kind of reference signal.
In addition; Can also whether adopt virtual MIMO (multiple input multiple output through the user; Multichannel is advanced multichannel and is gone out) whether technology divide and to coordinate; When the network side dispatched users was carried out the virtual MIMO transmission, this user's reference signal was just coordinated, and then used the user of virtual MIMO technology to adopt the reference signal that takies the pectination subcarrier.And do not use the user who adopts virtual MIMO technology to adopt the reference signal that takies continuous subcarrier.
Virtual MIMO technology can allow a plurality of user's data to send and take identical or overlapping running time-frequency resource, thereby improves resource utilization, elevator system capacity.Though the data of different user can be overlapping, reference signal but will guarantee quadrature, otherwise influences the performance that receiving terminal carries out the demodulation of multi-user data.Utilize embodiments of the invention, to the virtual MIMO user, utilize the reference signal of pectination frequency division, no matter whether user's running time-frequency resource is identical, can guarantee the orthogonality of reference signal, increased the virtual MIMO application flexibility.Because whether the user is that the virtual MIMO transmission is transparent to oneself, so generally can indicate the user to use which kind of reference signal with the MAC signaling of n bit.
At this moment; The interval of pectination subcarrier number can dynamically confirm according to the number of users that on identical running time-frequency resource, carries out virtual MIMO transmission, for example, and during the overlapping running time-frequency resource of 2 CUs; Then the pectination subcarrier spacing is 2 at least; During the resource of the time-frequency that 3 CUs are overlapping, also be that same resource is utilized three times, the interval of pectination subcarrier is 3 at least.
In the embodiment of the invention based on the coordination approach of reference signal; A kind of in addition implementation is; Two kinds are specially with reference to signal; A kind of modulation sequence of reference signal is from the specific sequence set in sub-district, and the modulation sequence of another kind of reference signal is from cell set particular sequence group, such as the specific sequence set of NodeB.The user specifically is treated to according to what the sequence that reference signal is used was carried out, carries out the emission or the reception of reference signal.
When two users do not need universal time coordinated, when overlapping, adopt reference signal by the sequence modulation in the specific sequence set in sub-district such as two users' running time-frequency resource.When two users need universal time coordinated; Complete when overlapping such as two users' resource; Can adopt by cell set particular sequence group, such as the sequence modulation corresponding reference signal in the specific sequence set of NodeB, promptly the wherein sequence set of some sub-districts is all adopted in three sub-districts under NodeB; And two users are shifted with the different time of same sequence and distinguish, and obtain the quadrature of sequence.
Wherein, under above two kinds of coordination approach based on reference signal, when indicating the reference signal of employing for the user, can use the MAC signaling of n bit or this user of RRC signaling indication to adopt which kind of reference signal in the embodiment of the invention, n can get 1.When adopting discontinuous subcarrier; Also need indicate the information of concrete subcarrier in the discontinuous subcarrier that the user uses; For example, concrete which " comb " in the pectination subcarrier, and the possible time cyclic shift signal that is somebody's turn to do " comb " corresponding reference signal.
Present embodiment can be more than two kinds based on the reference signal in the coordination approach of reference signal, can also be more kinds of, for example takies the reference signal of pectination subcarrier, its subcarrier spacing R=1, and three kinds of 2,3 with reference to signal.Specifically similar with two kinds, no longer detail once more.
The coordination based on reference signal of the embodiment of the invention can dynamically indicate the user to carry out the coordination of reference signal, reduces the interference of sub-district.
In real system, except up user's reference signal, also have some physical layer signals, such as, the up preamble targeting signal that inserts at random.Also be the sequence that has some characteristic through modulation, and receiving terminal utilize the characteristic of sequence to distinguish.With the question marks of above-mentioned reference signal seemingly, this type signal also need reduce presence of intercell interference, so the described coordination approach of embodiments of the invention is suitable equally.For the targeting signal that inserts at random, be applicable to and carry out the user that switch the sub-district, to reduce the suffered interference of signal.
Fig. 4 is the coordination approach flow chart of the embodiment of the invention based on modulation system.The flow process based on the coordination approach of modulation system of the embodiment of the invention is specially:
401, confirm the modulation system that user data signal adopts;
402, adopt this modulation system to carry out signal processing with user oriented signaling indication user.
Wherein, the user oriented signaling of employing can be towards unique user or one group of user signaling for the user oriented signaling.Such as the signaling towards unique user, MAC signaling or RRC signaling have dynamic broadcast signaling etc. towards one group of user signaling.This coordination approach, the coordination that can dynamically indicate the certain user to modulate, the coordination that the user can modulate flexibly.
The coordination approach based on modulation system of the embodiment of the invention can have two kinds of modulation systems, and a kind of is that two users' modulation constellation overlaps on together (superimposing); A kind of in addition is independently to modulate, and does not carry out the overlapping of modulation constellation.Also can have multiple or other tuneable modulation systems.
The mode that concrete constellation overlaps is following:
It is s that the user of hypothetical boundary place uses the signal after QPSK (Quadrature Phase Shift Keying, the QPSK) modulation
1(t)=x
1+ y
1J, wherein j representes the imaginary part of plural number, the signal of power adjustment back emission is c
1S
1(t), c
1It is power adjusting factor.The modulation signal of the sub-district internal user of coordinating is c
2s
2(t), c wherein
2Be power adjusting factor, s
2(t)=x
2+ jy
2, be the signal of QPSK modulation, then the signal of the emission of constellation stack is: c
1s
1(t)+c
2s
2(t), in general, c
1＞c
2, promptly boundary user needs more power.For two users' that coordinate demodulation, boundary user is c
2s
2(t) be regarded as disturbing, carry out demodulation.And the inner user in sub-district, can be earlier c
2s
2(t) be regarded as disturbing, come out boundary user's signal demodulation, carry out interference eliminated, remove boundary user's interference, carry out c again
1S
1(t) demodulation.
When not carrying out the modulation of constellation stack, that suppose to receive is c
2s
2(t), there is not c
1S
1(t), therefore, need not carry out interference eliminated.
Preferable, the coordination approach based on modulation system is applied to down link; To the user of the boundary of same sub-district, and the inner user in sub-district coordinates, when the same resource of two CUs coordinating; When for example taking identical subcarrier, carry out constellation and overlap.
Through the MAC signaling, the perhaps RRC signaling user coordination of whether modulating, whether the inner user of notifying cell has carried out the coordination of modulation very flexibly, and then the inner user in sub-district adopts the mode of corresponding demodulation, reduces the interference of sub-district.
The described coordination approach of the embodiment of the invention is applicable to that the user of two sub-districts coordinates, and does not need all sub-districts on every side all to coordinate, and does not also need all users of two sub-districts to coordinate.The user who coordinates can obtain to disturb less benefit, not have the interference between the user of user and coordination of coordination to remain randomized, can be not influenced.
