Description
Technical field
The present invention relates to wireless communication field more particularly to a kind of data dispatching method, device and with interior relaying.
Background technology
Relaying is exactly to increase the intermediate node (relay station) with wireless backhaul function between macro base station and mobile station, right
The downlink signal of macro base station or the uplink transmitting signal of terminal carry out at the base band such as demodulation decoding and scheduling of resource
Reason, then recompile, modulate, being transmitted to terminal or macro base station after regenerative amplification.Therefore, relaying Relay can effectively inhibit
The lifting of network interferences improves the q＆r of signal transmission, overcomes the interference problem of wireless discharging-directly station.
Relay be divided to for interior Relay with two kinds of outer Relay.With interior relaying refer to the accession to link (relay station and terminal it
Between) and return link (between relay station and base station) use the relay form that is transmitted of identical frequency, as shown in Figure 1, frequency band 1
Identical frequency is used with frequency band 2；Relay form of the link with return link using different frequency is referred to the accession to outer relaying.
For will occur since return link and access link operate in identical frequency resource with interior Relay
The case where transmitter of Relay generates self-interference to receiver.In order to solve the problems, such as that this self-interference, R10 standards define
The mode of running time-frequency resource separation, i.e. Relay cannot emit to base station eNB again while receiving the data that terminal UE is emitted.
Therefore return link is all made of the mode of time-sharing work (TDM) with access link.
3GPP36.216 defines the subframe proportioning of return link, and as shown in table 1, wherein U represents uplink, and D represents downlink.
Macro station subframe matches format generally using 2 mode (3DL of proportioning:1UL).It needs to take into account in actually showing net application with interior Relay
The resource allocation of return link and access link, it is therefore proposed that return link is by the way of proportioning 7 or proportioning 8.
Table 1
Wherein, by taking the configuration of return link subframe proportioning 7 as an example, illustrate the resource-constrained problem of access link.
Table 2
As shown in table 2, return link carries out data transmit-receive in subframe 2,4,8, access link subframe 0,1,3,5,6,
7, data transmit-receive is carried out on 9.
It can be seen from Table 2 that only there are one sub-frame of uplink for access link, therefore there are the downlink of part access link
The hybrid automatic repeat-request HARQ feedback of frame can not carry out.According to the downlink HARQ feedback of 36.213 Time Division Duplex TDD of standard
The feedback sequential relationship of time sequence definition, access link is as shown in table 3.
Downlink association set indexK:{k0,k1,…kM-1}for TDD
Table 3
Therefore the subframe of comprehensive return link matches format 7, the HARQ sequential of access link can be combed out, such as 4 institute of table
Show, wherein A indicates that access link, M indicate return link.
Table 4
By seeing on the downlink HARQ feedback time sequence definition of access link, 2 feeding back downlink subframe 4,5,6,8 of sub-frame of uplink
HARQ, the HARQ of 7 feeding back downlink subframe 0,1,3,9 of sub-frame of uplink；But since return link occupies sub-frame of uplink 2 as passback
The HARQ feedback of link, therefore cause subframe 5 and subframe 6 that can not carry out the feedback of HARQ.
Existing solution is that subframe 5 and subframe 6 provide in access link without scheduling, access link downlink subframe
Source becomes 3D+S from 4D+2S, propagation delay time will be caused larger in this way.In addition, if the following return link is matched using subframe
Format 9 or 10 causes access link resource-constrained then the downlink subframe of access link will be more rare.
