Technical field
The present invention relates to wireless communication field, more specifically, relate to system and the method thereof for being transmitted the interaction data between neighbor bss by MS, wherein, transmit the interaction data between neighbor bss by MS; And relate to a kind of communication system and method thereof.
Background technology
Advanced IMT next generation mobile networks improves the requirement to systematic function.There are some standard group or organized and drafted the file energetically to meet these requirements, expected that these drafts become the candidate target considered in advanced IMT evaluation process.The IEEE802.16m task groups of nearest establishment is modified to IEEE Std 802.16, to provide senior air interface, and has the performance for the improvement operated in licensed band.Its target is the demand of the next generation mobile networks of satisfied advanced IMT.
Along with the technological development that target is advanced IMT, adjacent BS (base station) needs to employ new technology to cooperate with each other.The neighbor bss carrying out control information exchange is coordinated to become more and more frequent, performs adjacent BS and to coordinate thus the neighbor bss that BS cooperates with it exchanges some control informations, channel information, or requests/response messages.This coordination is all necessary for the several functions in mobile communication, such as, switch fast, network MIMO (Multiinputoutput), and interference is eliminated, and segment resource is reused, MBS etc.Such as, in the handover, the BS of service must consult for the potential candidate of target BS and adjacent BS, to check whether adjacent BS is ready to accept mobile MS.Fig. 1 shows the schematic diagram of the control information exchange coordinated for neighbor bss.
In this operating process, serving BS broadcasts sends to neighbor bss and prenotices request, and this request of prenoticing comprises the environment configuration information of MS, and this neighbor bss sends it back a response, and this response comprises the service level prediction that have estimated HO time and HO and optimize.When completing switching, target BS also sends notice to old serving BS broadcasts: now by its management MS (travelling carriage), thus old serving BS broadcasts can discharge all MS resources.Another example is that the neighbor bss for disturbing elimination or component frequency resource to reuse is coordinated.Eliminate to disturb or reuse resource, between adjacent BS, exchange the information of some T/Fs scheduling and share the information of these scheduling.
Between BS, an example of exchange data information is that the descending data to MS are transferred to adjacent BS by backbone network by a BS, can be used for MBS (multicast service).
Stand-by period requirement is strictly improve for adjacent BS cooperation control.The less stand-by period will reduce possible service disruption and improve performance.
Usually transmit existing neighbor bss by backbone to control to coordinate.Such as, exchanged by backbone network and adjacent prenotice request/response for the neighbor bss negotiation message switched.Due to the transmission performance that it is larger, backbone network is applicable to transferring large number of data.But co-ordination message transmission route is selected and the stand-by period depends on trooping belonging to the position of these BS and these BS very much.Therefore, transmission latency is unpredictable.When involved BS does not belong to identical trooping, may need through the longer time.Define the controller making neighbor bss belong to identical of trooping.Such as, if BS belongs to the WAC in identical WiMAX, or belong to the identical RNC in 3GPP, then these BS belong to identical trooping.
As an example, in WiMAX network, the BS of coordination whether belong to Route Selection that identical WAC makes to exchange for neighbor bss control information and the stand-by period different.Fig. 2 a shows the schematic diagram of exchange of control information between the BS belonging to identical WAC.These control messages exchanged are exchanged by they common WAC and are forwarded, and therefore, need through the less stand-by period.
Fig. 2 b shows the schematic diagram of exchange of control information between the BS not belonging to same WAC.In order to coordinate, BS1 is first to its oneself WAC1 communicating control information.Afterwards, by router, the control information received from WAC1 is forwarded to WAC2, wherein this information may through IP encapsulation/decapsulation.When this message arrives the WAC2 belonging to adjacent BS2, WAC2 continues this message to be forwarded to object BS2.As can be seen from this process, total stand-by period comprises transmission delay, Route Selection/switching delay, and encapsulation/decapsulation also may be had to postpone.Thus be uncertain for total stand-by period of control information transmission.
In a word, be uncertain for the stand-by period by backbone network exchange of control information between adjacent BS, and waiting time depend on which adjacent BS position and BS belong to and troop.If involved BS belongs to different trooping, then may through longer time delay (that is, these belong to the BS of the different WAC in WiMAX).
Along with quick switching, interference is eliminated, the more and more stricter time delay demand of network MIMO etc., and adjacent BS coordinates to become more and more important and frequent.

Embodiment
Below, the preferred embodiments of the present invention will be described with reference to the drawings.In the accompanying drawings, identical element is by by identical reference symbol or numeral.In addition, in following description of the present invention, the specific descriptions to known function and configuration will be omitted, to avoid making theme of the present invention unclear.
Owing to adopting wired mode to carry out the forwarding of the control information between neighbor bss in prior art, so the total stand-by period for control information transmission is uncertain, therefore, may there is longer time delay.This cannot accept for the communication requiring time delay lower.
The present invention proposes a kind of BS-BS data transmission scheme through MS.Namely, interaction data between adjacent BS is transmitted by utilizing MS, wherein these data comprise user data, (can be such as the data of the MS be transferred in neighboring BS coverage area, or the data that the MS in neighboring BS coverage area sends), the data transmitted between neighbor bss are needed for the control information that neighbor bss is coordinated etc.Fig. 3 a shows the schematic diagram according to the system for being transmitted the interaction data between neighbor bss by MS of the present invention.With reference to figure 3a, it is overlapping covered that MS is positioned at two adjacent BS.First BS1 sends the interaction data of neighbor bss to MS, the interaction data of the neighbor bss received from BS1 is transferred to adjacent BS2 by MS afterwards.Such as, BS1 sends the control information being used for neighbor bss and coordinating to MS, then the control information received is forwarded to BS2 by MS.Be appreciated that the number of BS2 can be one or more.Owing to being performed the interaction data transmission between neighbor bss by MS, such as, control information exchanges, instead of performs control information exchange by the backbone network with uncertain Route Selection and stand-by period, can reduce total stand-by period of transfer of data.
Fig. 4 a shows an exemplary construction figure according to BS1 of the present invention.Wherein, BS comprises dispensing device 41, receiving system 42, neighbor bss conditioning unit 44 and BS control device 43.Dispensing device 41 sends data for the MS in this cell coverage area, such as, for the control information that neighbor bss is coordinated; The data that receiving system 42 sends for receiving MS in this cell coverage area or neighbor bss; BS control device 43 is for the sending/receiving of control data and process and perform control to MS, and neighbor bss conditioning unit 44 for identifying the MS in neighbor bss superimposed coverage area, and utilizes dispensing device 41 to send the interaction data of neighbor bss to the MS identified.Neighbor bss conditioning unit 44 may be used for setting up channel.The structure of BS2 and the similar of Fig. 4 a, omit the description to it here, to avoid repetition.
Fig. 4 b shows an exemplary construction figure according to MS of the present invention.Wherein, MS comprises dispensing device 401, receiving system 402, MS first control device 403 and MS second control device 404.Dispensing device 401 and receiving system 402 are respectively used to send/receive data.MS first control device 403 is for processing (if necessary) the data receiving/send, MS second control device 404 is for by the channel between neighbor bss or adopt MAP IE, the mode of data pulse string sends the interaction data of neighbor bss, such as, the control information for coordinating between neighbor bss is forwarded.Wherein, MS does not process the interaction data of the neighbor bss received from BS1, but is sent to BS2 as it is.The interaction data of the neighbor bss that BS1 sends is transparent for MS.
Because the present invention to perform the transmission of the interaction data between neighbor bss by MS, and these data comprise user data, the data transmitted between neighbor bss are needed for the control information that neighbor bss is coordinated etc., such as, be transferred to the data of the MS in neighboring BS coverage area, or the data etc. that the MS in neighboring BS coverage area sends.Below by be forwarded control information that being used between neighbor bss coordinate by MS for example, with reference to figure 3b, composition graphs 3a and Fig. 4 a, 4b describe the flow chart forwarding control information.
First, identify a MS in the overlay area that BS1 and BS2 is overlapping at the neighbor bss conditioning unit 44 of S31, BS1 and the adjacent coordinator device of BS2, for forwarding the control information for coordinating, wherein BS2 and BS1 is adjacent.Usually, in the overlay area of overlap, perform the exchange of the most control information for neighbor bss coordination for MS (such as, switching for MS).Although in this embodiment, employ a MS, be understandable that and also can use multiple MS.
Afterwards, between BS1, MS and between MS and BS2, channel is set up at the neighbor bss conditioning unit 44 of S32, BS1.
Particularly, after the MS in identifying this and be overlapping covered, BS1 sets up the channel between MS, for communication.And BS1 sends message by backbone network to BS2, notice BS2 and MS sets up channel.BS2 after such a message has been received, sets up the channel communicated with MS.Between BS1 and MS, and the channel set up between MS and BS2 can be one-way channel or two-way channel.This channel can be the pulse train distributed, Dedicated Control Channel and CDMA control channel etc.
Optionally, common signal channel can be set up between MS and BS2.This common signal channel refers to channel between MS (can be multiple) and multiple BS2, that shared by multiple BS2.First BS1 distributes a Resource Block, and afterwards, multiple BS of BS notice relevant (such as, adjacent) retain identical Resource Block, thus using this reserved identical Resource Block as common signal channel.MS can carry out up link broadcast by using the common signal channel shared by multiple BS2 to control information.MS is by common signal channel transmitting uplink control information, and the control information transmitted by this common signal channel is received by multiple BS2.
Such as, build CDMA control channel, thus for BS1 and BS2 overlapping covered in the transmission of control information of one or more MS to set aside some time-frequency resource, and these MS can use the CDMA transmission signal of encoding in advance.Optionally, MS uses the reserved CDMA control channel of adjacent BS2 to be adjacent BS2 communication.CDMA control channel may be used for up link and down link.
In addition, the channel resource of this distribution can be notified to multiple BS.Thus multiple BS monitors this common signal channel and receives the control message of MS forwarding.And clearly, the present invention can also use other channel of the control information transmission coordinated for adjacent BS by MS.
Due to the unidirectional or two-way channel by setting up between MS and BS1 and BS2, or use pre-assigned common signal channel, MS can safeguard the channel with BS1 and BS2 simultaneously, communicate with BS1 with BS2 while of such, and without the need to performing with the handoff procedure re-starting registration in BS2, and also do not need to utilize backbone network to perform the forwarding of control information, the stand-by period of control information transmission can be reduced.
Fig. 6 shows the schematic diagram of the two-way channel between MS and BS.Suppose that MS has registered and has been attached to BS1.Downlink/uplink communication between MS and BS2 occupies the CDMA control channel that BS2 distributes.This control channel of original allocation, for the signal transfer control between the MS in BS2 and its coverage.
In the present invention, MS is allowed to use its oneself neighbor bss 2 CDMA control channel, for forwarding adjacent BS control information.Fig. 5 shows an example according to the frame structure for channel allocation of the present invention.In this frame structure, be assigned with two-way channel.It is only an example, and the present invention can also use other channel except CDMA control channel.
At S33, send control information for coordinating by the dispensing device 41 of BS1 to MS.When a BS have need exchange control information time, BS can by distribute channel or other method (such as, MAP IE, data pulse string, etc.) send control information.
Receive this control information at the second control device 404 of S34, MS by MS receiving system 402 and also forward this control information by the channel set up to BS2.The control information received is transmitted to adjacent BS2 from BS1 by dispensing device 401 by second control device 404 as it is, and does not process this control information.
BS1 can send to MS the control information passing through encryption, and this control information is transparent to MS.MS, after the control information receiving this encryption, does not decode to obtain data content to this message, and only by dispensing device 401, the message received is transmitted to adjacent BS2 from a BS1 as it is.When the disposal ability of MS allows, MS can forward this control information in a frame.
BS2 is from MS receiving control information.After establishing the channel between MS and BS2, BS2 is known the channel of existence and is monitored channel.When channel transmits through monitoring and controlling channels, BS2 receives this control information.
Along with MS moves, channel condition changes, and BS judges whether to need the channel for information exchange.If do not needed, BS can discharge channel.And BS can also upgrade channel according to the change of channel condition.
Here, although to utilize MS to forward for the control information between the neighbor bss coordinated, be illustrated its method, understandable, the interaction data of neighbor bss can also be sent in the same way by MS.Wherein, MS does not process the interaction data of the neighbor bss received, but the interaction data of the neighbor bss sent by BS1 is sent to BS2 as it is.
Owing to establishing the unidirectional or two-way channel between BS1 and MS and MS and BS1, so MS while the existing method of use carries out communicating with BS1, with the channel communication of BS2 by setting up, thus can not need to perform switching, just can carry out alternately with BS2.And the data being used for MS self, except can transmitting the interaction data between neighbor bss, can also be sent to BS2 by MS, the data for MS self are such as channel measurement, handover request, MS upstream data etc.Or BS2 sends data to MS executive communication etc.Optionally, data can be passed to multiple BS by the common signal channel distributed by MS simultaneously.
The present invention transmits the interaction data between neighbor bss by MS, can be applied to and require that the interaction data between higher neighbor bss transmits to time delay.Owing to not needing to utilize backbone network to perform the transmission of the interaction data between neighbor bss, so, by utilizing MS, the stand-by period of the transmission of the interaction data between neighbor bss can be reduced.Compared with coordinating with the traditional B S by backbone, the BS by MS of the present invention coordinates to be had predictability and spends the less stand-by period, thus improves the communication performance between neighbor bss.
Although with reference to specific embodiment, invention has been described, is understandable that the present invention is not limited to these embodiments.Should be clear, under the prerequisite not departing from scope and spirit of the present invention, those of ordinary skill in the art can change embodiment or revise.
