Description
Technical field
The present invention relates to mobile communication wireless connecting system technology, relate to adopt in the future mobile communication system relaying (Relay) or rather or claim the wireless access system of relay station, trunking (RS) technology, be used for solving the mode of the special wireless link orthogonality of this system.
Background technology
Coverage is an important technology index of wireless access system, and wireless access system generally passes through the covering of base station or access point realization to the coverage.But because the mobility of terminal, terminal might be in outside the service area fully, thereby can't obtain the wireless access service; Even end is within service area, the transmission of signal still may be subjected to covering of obstacle on the transmission path, thereby causes the decline of service quality.In the mobile communication system in future, need transmit the very data of two-forty (as 1Gbps), simultaneously because the restriction of bandwidth assignment condition, future mobile communication system very likely uses higher communication band (as 5GHz), these two factors all can cause the rapid decline of coverage, if solve the problem of coverage by the quantity that increases base station or access point, then base station/number of access point is increased in the construction and the operating cost that can have influence on network to a great extent.Based on above-mentioned consideration, for the increase of the seamless covering that solves service area and power system capacity and save cost as much as possible, employing relaying (Relay) technology will be proposed in the technical scheme of future mobile communications.Outside UE is positioned at service area or signal quality can not satisfy the demands the time, can carry out transfer to signal by RS, with expansion that realizes the coverage or the reliability that improves transmission.
Relaying (Relay or RS) connects base station (BS) and user terminal (UE) by Radio Link, and transmits the data between them.General document thinks that RS is operated in the transmission duplex mode, but RS one co-exists in four class links, be uplink downlink between RS and the BS and the uplink downlink between RS and the UE, therefore both needed to take all factors into consideration the duplex mode of link between link between RS and the BS and RS and the UE, simultaneously also need to take all factors into consideration the duplex mode of up link and down link, comprise up link and BS the down link to RS and RS to UE of UE to RS and RS to BS.But current document is seldom taken all factors into consideration these factors.
The basic structure of Relay system can be described by Fig. 1.Referring to Fig. 1, provide the basic structure of the wireless access system of the following Relay of support among the figure.One co-exists in four class links in the system: access downlink Access DL (down link), insert up link Access UL (up link), relaying down link Relay DL and relay uplink Relay UL, the up link of corresponding respectively expression BS/RS to the down link of UE, UE to BS/RS, the BS up link to the down link of RS and RS to BS.In order to reduce the mutual interference of each bar link, it is generally acknowledged that these four links all should use the resource of quadrature.From data flow direction, inserting the data that the descending Relay DL of descending Access DL and relaying transmits is the downstream data flow of BS/RS to UE, is the upstream of RS/UE to BS and insert the data that up Access UL and the up Relay UL of relaying transmit.Therefore, we can be treated to down link DL to Access DL and Relay DL, and Access UL and Relay UL are treated to up link UL, and Access DL and Access UL be treated to access link Access Link, Relay DL and Relay UL are treated to repeated link Relay Link.
From the above analysis as can be seen: for BS and RS, one has four class link Access DL, Access UL, Relay DL and Relay UL.But the character of only distinguishing link is not enough, and important problem is how to determine the working method of this four classes link.In existing wireless access system, it is generally acknowledged that Relay is operated in duplex mode: or perhaps the duplex mode of Access Link (Access DL and Access UL) and Relay Link (Relay DL and Relay UL), or perhaps the duplex mode of DL (Access DL and Relay DL) and UL (Access UL and Relay UL).But these two kinds of duplex modes have all been ignored Access link, Relay Link, DL and UL relation each other.Also be, thisly be divided into Access Link and Relay Link duplex mode isolatedly, or isolated the duplex mode that is divided into DL and UL, DL and UL will have been ignored, and the correlation between Access Link and Relay Link also just can not correctly be determined the working method of four class links.

A kind of trunking of realizing wireless link orthogonality in the cellular system of supporting relaying of the present invention utilizes forwarding module to realize method of the present invention, and this forwarding module is judged orthogonal manner and four worker's modes thereof of trunking; When judged result is during frequency division four worker's modes, this forwarding module to access downlink, insert up link, relaying down link and relay uplink and on time-domain and frequency domain, carry out quadrature respectively and cuts apart, and a pair of time transfer point is set and a protection frequency band is transmitted; When judged result is that the time-divisions four are during worker's mode, this forwarding module to access downlink, insert up link, relaying down link and relay uplink and on time-domain, carry out quadrature and cuts apart by the order of selecting, and between each time period, guardtime is set and transmits at interval; When judged result is frequency division four worker's modes; this forwarding module to access downlink, insert up link, relaying down link and relay uplink and on frequency domain, carry out quadrature and cuts apart by the order of selecting, and the frequency band protection be set between each frequency band transmit at interval.
The time frequency division four worker's schemes frame structure as shown in Figure 2, provide three kinds of embodiments (1), (2), (3) among the figure.Wherein the T representative sends, and R represents reception, and abscissa is the time, and ordinate is a frequency, and in each embodiment, the duplex of BS, RS and UE/four worker's modes are represented with three vertical figure respectively, but the origin of coordinates is the same.On time-domain, the time frequency division four workers only need a pair of time transfer point, the resource of can saving time, and kept the support asymmetric traffic and utilized the characteristic of the mutual benefit of channel (reciprocity).
The time frequency division four worker's schemes (1) in, for BS, DL and UL are that time division duplex is received and sent out (DL/T, a UL/R), Access Link and Relay Link are that Frequency Division Duplexing (FDD) is received and sent out; For RS, DL and UL are that time division duplex is received and sent out, Access Link and Relay Link are that Frequency Division Duplexing (FDD) is received and sent out, because at synchronization and deposit Access Link and Relay Link, one of them is to send, another is to receive, and therefore, RS needs a protection frequency band to avoid transmitting-receiving to disturb; For UE then is single frequency band time-division up-downgoing transmission duplex.In the present embodiment, the quadrature that RS carries out up transmission/reception link and descending reception/transmission link is in time cut apart, and the quadrature that carries out access link and repeated link on frequency is cut apart.This time frequency division four worker's schemes (1) only be fit to Relay Link and Access Link and be operated in situation on the frequency band that two independences do not disturb, that is to say that this mode is fit to the outer mode of operation of band that Relay is operated in double frequency-band.
In like manner, the time frequency division four worker's schemes (2) in, for BS, Access Link and Relay Link are that time division duplex is received and sent out, up-downgoing is that Frequency Division Duplexing (FDD) is received and sent out; For RS, DL and UL are that Frequency Division Duplexing (FDD) is received and sent out, and Access Link and Relay Link are that time division duplex is received and sent out, and synchronization is also deposited up transmission/reception and descending reception/transmission, also the protection frequency band need be arranged between up-downgoing; For UE, then be frequency division up-downgoing transmission duplex.In the present embodiment, the quadrature that RS carries out access link and repeated link is in time cut apart; The quadrature that carries out up transmission/reception link and descending reception/transmission link on frequency is cut apart.Therefore, only suitable DL of this scheme (2) and UL are operated in the not situation of interference band of two independences, promptly traditional FDD mode.
Equally, the time frequency division four worker's schemes (3) in, for BS, Access Link and Relay Link are Frequency Division Duplexing (FDD), receive with transmission be time division duplex; For RS, Access Link and Relay Link are Frequency Division Duplexing (FDD), and time division duplex is received and sent out, synchronization and depositing/descending reception or on/descending transmission, the protection frequency band need be arranged between up-downgoing; For UE, then be operated in the up transmission of time-division and the descending receive mode of single frequency band.In the present embodiment, the quadrature that RS carries out up/descending reception and up/descending transmission link is in time cut apart, and the quadrature that carries out access link and repeated link on frequency is cut apart.This scheme (3) only is fit to Relay Link and Access Link and is operated in situation on the frequency band that two independences do not disturb.
During from above-mentioned three kinds frequency division four worker's modes for example as can be seen, the time RS in frequency division four worker's schemes, need a pair of time transfer point, all need to be operated in dual-band modes, and between two frequency bands the protection frequency band will be arranged.Like this, the Relay of frequency division four worker's modes relatively is fit to be operated in the FDD system when being operated in, here so-called FDD system is meant that BS is operated in the FDD mode, be that DL and UL are operated in different frequency range respectively, perhaps need the Relay Link of Relay to be operated in the dual-band modes of the frequency range different with Access Link.
Expression embodiment illustrated in fig. 2: the Relay of frequency division four worker's schemes (2) is fit to be operated in the FDD system during employing; The Relay of frequency division four worker's schemes (1) or (3) is fit to be operated in the system of independent repeated link frequency band during employing.
The frame structure of frequency division four worker's schemes also provides three kinds of embodiments (1), (2), (3) as shown in Figure 3 among the figure.In each embodiment, the duplex of BS, RS and UE/four worker's modes are represented with three vertical figure respectively, but the origin of coordinates is the same, and T represents transmission, and R represents reception, and abscissa is the time, and ordinate is a frequency.RS carries out quadrature by the order of selecting to access downlink, access up link, relaying down link and relay uplink on frequency domain cuts apart, and the frequency band protection is set at interval between each frequency band.On time-domain; RS in three kinds of embodiments is operated in a time period; but no matter in which kind of scheme, all need 3 protection frequency bands at least, with the descending reception of relaying, the up transmission of relaying, insert descending transmission and insert up reception respectively by being discharged on the different frequency ranges.Because the frequency resource that takies is many, so is difficult to find these frequency ranges to be fit to this application in the reality.Wherein, scheme (1), the order of selecting on frequency domain is from low to high: insert up reception link, the up transmission link of relaying, insert descending transmission link, the descending reception link of relaying.Scheme (2), the order of selecting on frequency domain is from low to high: insert up reception, insert descending transmission, the up transmission of relaying, the descending reception of relaying.The order that scheme (3) is selected on frequency domain is from low to high: the up transmission link of relaying, the descending transmission link of access, the up reception link of access, the descending reception link of relaying.
The frame structure of time-division four worker's schemes as shown in Figure 4.Provide three kinds of embodiments (1), (2), (3) among the figure.In each embodiment, the duplex of BS, RS and UE/four worker's modes are also represented with three vertical figure respectively, but the origin of coordinates is the same, and T represents transmission, and R represents reception, and abscissa is the time, and ordinate is a frequency.As can be seen from the figure; time-divisions four worker all is operated in a frequency band; but need a plurality of time periods; and need protection at interval; relatively be fit to the TDD system; here so-called TDD system is meant that BS is operated in the system of TDD mode, and promptly DL is operated in the different time periods respectively with UL, and well supports asymmetric traffic and utilize the characteristic of the mutual benefit of channel (receprocity).RS carries out quadrature by the order of selecting to access downlink, access up link, relaying down link and relay uplink on time-domain cuts apart, and guardtime is set at interval between each time period.
Embodiment (1) wherein, the order that RS selects on time-domain is from low to high: insert descending transmission link, insert up reception link, the descending reception link of relaying, the up transmission link of relaying.Embodiment (2), the order that RS selects on time-domain is from low to high: insert descending transmission link, the up transmission link of relaying, insert up reception link, insert descending reception link.Embodiment (3), the order of selecting on time-domain is from low to high: insert descending transmission link, the descending reception link of relaying, insert up reception link, the up transmission link of relaying.
In time-divisions four worker's scheme (1), Relay Link is concentrated the latter half that is placed on every frame, to be unfavorable for flexible transfer, and, Relay Link also may with the up link of the BS that does not have Relay to be connected between produce serious up-downgoing and disturb, simultaneously, this frame structure causes having the frame structure of Relay BS that connects and the BS that does not have Relay to be connected that bigger variation takes place.
Adopt the Relay of time-divisions four worker's scheme (2) and (3) to be fit to be operated in the TDD system; in time-divisions four worker's scheme (2) and (3); all Relay Link and Access Link are intersected separately; different is the process that has increased the up-downgoing conversion of Relay Link and Access Link in scheme (2); also be; at the up transmission link of relaying and insert the protection of up reception link between the shared time period at interval at interval, with the interference between avoiding sending and receive greater than the protection of other link between the shared time period.The BS that so just requires Relay to connect increases transfer point length, causes the bigger adjustment of BS frame structure.But in (3), the up-downgoing that can introduce between the stronger RS is disturbed, specifically as shown in Figure 5.Among Fig. 5, neighbor cell base station BS1, BS2, the relaying RS1 of BS1 is adjacent with the relaying RS2 of BS2, if there is not mutual coordination function between neighbor cell BS1 and BS2, up-downgoing difference change-over time that may be separately, and may have line-of-sight transmission between RS1 and RS2, thereby cause the strong up-downgoing between RS1 and the RS2 to disturb (shown in dotted arrow among the figure).
In fact; except three kinds of schemes shown in Fig. 4; can also be by on time-domain, arranging the order of AccessDL, Access UL, Relay DL and Relay UL; carrying out quadrature by the order of selecting on time-domain cuts apart; guardtime is set at interval between each time period; thereby can be combined into many kinds of time-divisions four worker's scheme, will determine according to concrete demand, such as see that from protection interval angle the sort of mode resource utilization is the highest as for concrete which kind of scheme of selecting.
The embodiment of complex chart 2 to Fig. 4 is as can be seen: the Relay of frequency division four worker's schemes (2) is fit to be operated in the FDD system when adopting; The Relay of frequency division four worker's schemes (1) or (3) is adapted at using in the system of independent repeated link frequency band during employing; Adopt the Relay of time-divisions four worker's scheme (2) and (3) to be fit to be operated in the TDD system, but still need take all factors into consideration when specifically selecting.
The above is preferred embodiment of the present invention only, is not to be used to limit protection scope of the present invention.
