By the method, the transmission capacity of the backhaul signal is increased, and the performance of a backhaul link is improved.
Description
Technical field
The present invention relates to wireless communication system, particularly relaying (Relay) sends the method for returned signal.
Background technology
In strengthening Long Term Evolution (LTE-A:LTE Advanced) system, relaying has and the general similar function in base station, such as the sub-district ID that oneself is arranged, can independently send Physical Downlink Control Channel and the high-level signaling etc. of oneself.It mainly is divided into relaying (In band Relay) and band outer relaying (Outband Relay) in the band.Being primarily aimed at the interior relaying of band below is described.
Relaying requires backhaul (Backhaul) link and access (Access) link to adopt the same band transmission in the band.A present basic assumption is that back haul link and access link are based on the Time Division Multiplexing mode and come multiplexingly, and promptly relaying can not be simultaneously to base station and relaying UE (being specially the UE of relay management) transceive data.That is to say, be used for the base station and send data to the downlink resource of relaying and be used for downlink resource that relaying sends data to relaying UE and be based on the TDM mode, and relaying sends data to the ascending resource of base station and ascending resource that relaying UE sends data to relaying and also is based on the TDM mode.Based on this, at present in the concrete configuration to back haul link resource and access link resource, the descending back haul link resource of relaying is to be that the subframe of MBSFN realizes by taking type, and up back haul link resource is to realize by taking sub-frame of uplink.
But the descending sub frame number that comprises at every frame in the LTE-TDD system is more than the situation of sub-frame of uplink, thisly come collocating uplink back haul link resource can influence the HARQ transmission performance of downlink data by occupying sub-frame of uplink, mainly be because: take to the back haul link of base station when a sub-frame of uplink is sent returned signal by relaying, just can not be used for the access link transmission of relaying UE to relaying, be relaying UE can not be in the sub-frame of uplink that back haul link takies transferring ACK/nack message, so, if a plurality of sub-frame of uplink are taken by back haul link, then all can not be used in these a plurality of sub-frame of uplink transmit to the ACK/NACK information of corresponding downlink data therewith, this has obviously influenced the HARQ performance, has also influenced the downlink throughput capacity of relaying.
In order to solve the problems of the technologies described above, prior art discloses the collocation method of another kind of back haul link resource and access link resource, specifically referring to Fig. 1.As shown in Figure 1, this method is configuration back haul link resource and an access link resource in a sub-frame of uplink, because relaying can not be simultaneously to base station and relaying UE transceive data, so back haul link resource and access link resource must be TDM.In the prior art, because a subframe is made up of two time slots, based on this, this method just one of them time slot as the access link resource, be used for uplink control signal and the data of transmission trunking UE to relaying, and another time slot as the back haul link resource, be used for the returned signal of transmission trunking to the base station.Need to prove,, need certain change-over time, so this method is also extracted certain-length out and is used for as change-over time in the back haul link resource because relaying changes to transmit status from accepting state between two time slots.Like this, because the access link resource can be used for transferring ACK/nack message, so, the method that Fig. 1 provided can realize that sub-frame of uplink that back haul link takies can transferring ACK/NACK feedback information, has avoided the loss to HARQ Effect on Performance and relaying throughput.
But because the covering of uplink is relevant with the length of access link resource occupation, promptly the slot length that takies of access link is long more, then the covering of uplink is big more, and in the said method, access link can only transmit in a time slot, and this has reduced the covering of uplink obviously; Also have, because relaying only disposes the back haul link resource that is used to send returned signal in a time slot of a subframe, be used for as change-over time but also will be partitioned into a part in this back haul link resource, this has obviously limited the capacity of returned signal.
Summary of the invention

In order to realize the flow process shown in Fig. 2 a, the access link resource that present embodiment sends the back haul link resource of returned signal to relaying being used to of adopting and is used to receive the signal that UE sends has been carried out corresponding configuration, describes in detail below.
At first, in order to increase the capacity of the returned signal that relaying sends, present embodiment is configuration back haul link resource and an access link resource in a plurality of sub-frame of uplink.In the present embodiment, when utilizing a plurality of sub-frame of uplink configuration back haul link resource the continuous in time principle configuration that takies according to back haul link resource in two sub-frame of uplink wherein.Referring to Fig. 2 b, Fig. 2 b is the schematic diagram of resource distribution in the embodiment of the invention one.In the present embodiment, with configuration back haul link resource in two sub-frame of uplink is example, present embodiment adopts multiplexing access link resource of the method for TDM and back haul link resource in sub-frame of uplink, and make the interior different order that adopts of two sub-frame of uplink shine upon access link resource and back haul link resource, during specific implementation, can comprise as Fig. 2 b: configuration is by the transmitting-receiving conversion of access link resource to the back haul link resource in first sub-frame of uplink, first time slot that is specially at first sub-frame of uplink is to dispose access link on the 2n time slot, is to dispose back haul link on the 2n+1 time slot at second time slot; Configuration is received conversion by the back haul link resource to sending out of access link resource in second sub-frame of uplink, and first time slot that is specially at second sub-frame of uplink is to dispose back haul link on the 2n+2 time slot, is to dispose access link on the 2n+3 time slot at second time slot; Like this, guaranteed the continuous in time purpose that takies of two interior back haul link resources of sub-frame of uplink.As can be seen, adopt the method shown in Fig. 2 b, only need to take place 2 transmitting-receiving conversions or send out the receipts conversion.
As for the position of changing between access link resource in the sub-frame of uplink and the back haul link resource, the embodiment of the invention is not specially limited, and the position of changing between access link resource and the back haul link resource in two sub-frame of uplink can be identical, also can be different.During specific implementation, the position of changing between access link resource and the back haul link resource in the sub-frame of uplink can determine in several ways, such as: dislocation can be disposed with high-level signaling; Perhaps dislocation can be predefined, and for example predefine dislocation is intersection of two time slots comprising at sub-frame of uplink etc.
As what describe in the background technology, in sub-frame of uplink, relaying changes to transmit status from accepting state, need certain change-over time, do not limit the more specific location information of this change-over time in the present embodiment, as a kind of embodiment, can be configured in this change-over time in the resource that back haul link takies, specifically shown in Fig. 2 b.
Based on the described configuration of Fig. 2 b, can realize that relaying receives the signal that relaying UE sends on the access link in the front portion of first sub-frame of uplink (such as the 2n time slot); Relaying (such as 2n+1 and 2n+2 time slot) on the continuous back haul link resource of two sub-frame of uplink sends up back haul link signal to the base station; Relaying receives the signal that relaying UE sends on the access link at the rear portion of second sub-frame of uplink (such as the 2n+3 time slot).Wherein, present embodiment utilizes the continuous in time back haul link resource transmission returned signal of configuration in two sub-frame of uplink, can comprise during specific implementation: utilize the continuous in time back haul link resource of configuration in two sub-frame of uplink to send different data blocks respectively, promptly use different HARQ processes to transmit different data blocks; Certainly, also can utilize the continuous in time back haul link combination of resources of configuration in two sub-frame of uplink to send same data block to coming together.Note, if the position of changing between access link resource and the back haul link resource is positioned at the intersection of two time slots that sub-frame of uplink comprises, the back haul link resource of configuration is actual in two sub-frame of uplink then combining is equivalent to the resource quantity that a sub-frame of uplink comprises.
So far, realized the collocation method of the resource utilized in the embodiment of the invention by above-mentioned configuration.
Need to prove, in the present embodiment, because the back haul link resource of two interior configurations of sub-frame of uplink is continuous in time in the method shown in Fig. 2 b, based on this, present embodiment can utilize the reference signal in the back haul link resource of these two sub-frame of uplink to do channel estimating simultaneously, be that described relaying sends reference signal at second time slot of first sub-frame of uplink and first time slot of second sub-frame of uplink, this can obtain more precise channels estimated performance.
Embodiment shown in above-mentioned as can be seen Fig. 2 b is to dispose the back haul link resource according to the continuous in time principle of taking of back haul link resource in two sub-frame of uplink, preferably, as another embodiment of the present invention, can also adopt a kind of fairly simple method to dispose the back haul link resource, realize the flow process shown in Fig. 2 a.Be specially: in sub-frame of uplink, adopt multiplexing access link resource of method and the back haul link resource of TDM, and in a plurality of sub-frame of uplink, adopt same sequence to shine upon access link resource and back haul link resource.
Shown in Fig. 2 c, be example still with configuration back haul link resource in two sub-frame of uplink, then adopt same sequence to shine upon the access link resource in a plurality of sub-frame of uplink and the back haul link resource specifically comprises: configuration is changed to the transmitting-receiving of back haul link resource by the access link resource in first sub-frame of uplink, first time slot that is specially at first sub-frame of uplink is to dispose access link on the 2n time slot, is to dispose back haul link on the 2n+1 time slot at second time slot; Same configuration is by the transmitting-receiving conversion of access link resource to the back haul link resource in second sub-frame of uplink, first time slot that is specially at second sub-frame of uplink is to dispose access link on the 2n+2 time slot, is to dispose back haul link on the 2n+3 time slot at second time slot; Like this, guaranteed to adopt in a plurality of sub-frame of uplink same sequence to shine upon the purpose of access link resource and back haul link resource.As can be seen,, adopt the method shown in Fig. 2 c, need 3 transmitting-receivings of generation to change or send out to receive and change than Fig. 2 b.
In Fig. 2 c, similar described in the access link resource of configuration and the dislocation of back haul link resource and change-over time and Fig. 2 b repeats no more; It should be noted that, owing to adopt same sequence to shine upon access link resource and back haul link resource in two sub-frame of uplink in the method shown in Fig. 2 c, like this, the intersection of two sub-frame of uplink certainly will be in the change-over time of receiving and dispatching or sending out receipts at one, such as the change-over time from the back haul link resource to the access link resource among Fig. 2 c.
Because a subframe is made up of 2 time slots, and the latter half resource of sub-frame of uplink (such as second time slot of this sub-frame of uplink) is all taken by back haul link in the method shown in Fig. 2 c, and promptly all up symbols of comprising of sub-frame of uplink latter half resource are all taken by back haul link.Usually, channel measurement reference signal (SRS) among the LTE is to send on last symbol of sub-frame of uplink, and last the up symbol that has disposed in the method shown in Fig. 2 c in the sub-frame of uplink of back haul link all is used for the back haul link transmission, and this just means that also relaying UE can not send SRS in these two sub-frame of uplink.
More than be the description of embodiment one, below other embodiment provided by the invention be described.
Embodiment two:
Present embodiment mainly is the situation at a sub-frame of uplink configuration of current employing back haul link resource.In order to increase the capacity that relaying sends returned signal, the flow process that present embodiment provides specifically may further comprise the steps as shown in Figure 3:
Here, the back haul link configuration information of resource can comprise in the step 301: the resource that back haul link takies in sub-frame of uplink (being designated as situation 1) also can be included in resource that takies in the sub-frame of uplink and the back haul link resource section (being designated as situation 2) that is produced by GP.Respectively both of these case is described below.
At situation 1, at first, do not consider the transmitting-receiving change-over time of base station, promptly frame structure ideally is referring to shown in Fig. 4 (a).And under the actual conditions, generally there is the change-over time (be specially between the back haul link of base station and the access link conversion needed change-over time) of self transmitting-receiving the base station, here, be to obtain by the Timing Advance (TA) that disposes relaying the change-over time of base station transceiver, the sub-frame of uplink of supposing current employing is last sub-frame of uplink of having considered the frame structure after change-over time of base station transceiver, and, the rear portion resource that comprises in last sub-frame of uplink (such as second time slot) is used to dispose back haul link, and anterior resource (such as first time slot) is used to dispose access link, and then the frame structure of base station real work is referring to shown in Fig. 4 (b).Based on this, relaying also has the transmitting-receiving change-over time of self, comprises during specific implementation: by the TA of base station configuration relaying, so that the control relaying sends the timing of backhaul link signal, and the TA of relaying configuration relaying UE is specially: will send to relaying UE for the TA of relaying UE configuration; Time interval of generation between the resource of this resource that can make the access link of configuration in the sub-frame of uplink (also being last sub-frame of uplink) of employing and the back haul link of configuration, this time interval can be used as the change-over time (be specially the relaying execution and change needed change-over time between back haul link and the access link) of relaying transmitting-receiving, specifically referring to Fig. 4 (c).So, relaying just can utilize the frame structure shown in Fig. 4 (c) to send returned signal to the base station.As can be seen, adopt the frame structure among Fig. 4 (c), access link transmission and back haul link transmission have been realized in sub-frame of uplink, supporting simultaneously, and be independent of back haul link resource and access link resource the change-over time of relaying transmitting-receiving, and this has realized not influencing the purpose of access link and backhaul link performance.
And,, need TA by configuration relaying UE for realization situation 2 at situation 2, utilize sub-frame of uplink and GP to transmit returned signal.Specifically as shown in Figure 5.Wherein, Fig. 5 (a) is similar with above-mentioned Fig. 4 (a), all is desirable frame structure; If considered the change-over time of base station transceiver, wherein, be to obtain by the TA that disposes relaying the change-over time of base station transceiver.Here, suppose the rear portion resource distribution back haul link that last sub-frame of uplink of frame structure comprises, and by the suitable TA value of configuration relaying, also can be between the follow-up next subframe (descending sub frame) of this last sub-frame of uplink and this sub-frame of uplink back haul link resource section of structure, described back haul link resource section is produced by special time slot GP, specifically obtains by the GP in the sub-frame of uplink place frame structure that shortens current employing; In the back haul link resource section that produces by GP of structure, dispose back haul link, concrete shown in Fig. 5 (b).Fig. 5 (c) is a frame structure of relaying real work, during specific implementation, TA by the base station configuration relaying, so that the control relaying sends the timing of backhaul link signal, and TA by relaying configuration relaying UE, so that produce a time interval between the resource of the back haul link of the resource of the access link that disposes in the sub-frame of uplink of above-mentioned employing (also being last sub-frame of uplink) and configuration, this time interval can be used as the transmitting-receiving change-over time of relaying.So, relaying just can utilize the frame structure shown in Fig. 5 (c) to send returned signal to the base station.As can be seen, adopt the frame structure among Fig. 5 (c), access link transmission and back haul link transmission have been realized in sub-frame of uplink, supporting simultaneously, and be independent of back haul link resource and access link resource the change-over time of relaying transmitting-receiving, and this has realized not influencing the purpose of access link and backhaul link performance
Need to prove, in the present embodiment, back haul link resource in the sub-frame of uplink specifically can comprise when transmitting returned signal with the back haul link resource section that is produced by GP: the back haul link resource in the sub-frame of uplink can send different data blocks respectively with the back haul link resource section that is produced by GP, promptly use different HARQ processes to transmit different data blocks, also can be grouped together and send same data block the back haul link resource of sub-frame of uplink with by the back haul link resource section that GP produces.
And, in order to realize channel estimating,, can also only send reference signal on the back haul link resource in sub-frame of uplink here, for example the position of this reference signal can be identical with the reference symbol position of the sub-frame of uplink of LTE reality; Perhaps, send a reference signal on the back haul link resource in sub-frame of uplink, for example the position of this reference signal can be identical with the reference symbol position of the sub-frame of uplink of LTE reality, and on the back haul link resource section that produces by GP, send the reference signal that another one is different from back haul link resource transmission in the sub-frame of uplink, so that can do channel estimating in conjunction with these two different reference signals; Perhaps, redefine reference signal structure on back haul link resource that also can be in sub-frame of uplink and the back haul link resource section that produces by GP; In order to realize the compromise of channel estimating performance and reference signal expense, can correspondingly dispose the structure of suitable reference signal according to the number of up symbol in the back haul link resource section that produces by GP.In the present embodiment, because all back haul link resources are continuous in the frame structure, this helps obtaining more precise channels estimated performance.
In order to support this method, the dislocation of interior back haul link resource of sub-frame of uplink and access link resource can be disposed with high-level signaling in the present embodiment, i.e. the dislocation of access link resource and back haul link resource in the high-level signaling indication sub-frame of uplink; Perhaps this dislocation can be predefined, and for example predefine dislocation is the intersection of two time slots in sub-frame of uplink.And, preferably, the back haul link resource section that is produced by GP also can dispose with high-level signaling, for example the number of the up symbol of back haul link is disposed in high-level signaling indication by GP being used to of producing, and when carrying out the operation of above-mentioned transmission reference signal, also can indicate the reference signal structure that adopts on the back haul link simultaneously by high-level signaling.
As can be seen from the above technical solutions, in the method provided by the invention, if two sub-frame of uplink configurations of current employing back haul link resource, then according to the continuous in time principle configuration of back haul link resource in two sub-frame of uplink; So, relaying can receive the signal that UE sends on the access link in the front portion of first sub-frame of uplink; Relaying sends returned signal at the rear portion of first sub-frame of uplink and the front portion of second sub-frame of uplink to the base station; Relaying receives the signal that UE sends on the access link at the rear portion of second sub-frame of uplink; This is than prior art, increased the returned signal capacity, an if sub-frame of uplink configuration of current employing back haul link resource, then do not influence the principle configuration of access link performance and backhaul link performance needed change-over time according to conversion between back haul link and the access link, be no longer to take access link resource or back haul link resource than prior art change-over time, be specially: the base station sends to relaying with the back haul link configuration information of resource; Relaying sends returned signal according to the described configuration information that receives on described back haul link resource, this has also increased backhaul link capacity, and then has improved backhaul link performance.
The above only is preferred embodiment of the present invention, and is in order to restriction the present invention, within the spirit and principles in the present invention not all, any modification of being made, is equal to replacement, improvement etc., all should be included within the scope of protection of the invention.
