(1) owing to only having MAC (the Medium Access Control of a jumping, media access control) sublayer HARQ (Hybrid Automatic Repeat Request, mixed automatic retransfer) and RLC (RadioLink Control, wireless link control) ARQ of sublayer, TYPE II RELAY delay character is all better than TYPE I RELAY in most cases
(2) TYPE II RELAY does not have PDCCH (Physical Downlink Control Channel, physical down control link), so the minizone control channel interference of TYPE II RELAY application is applied lower than TYPE I RELAY
(3) the relative TYPE I of the price of TYPE II RELAY RELAY is more cheap.
Current TYPE II RELAY has defined some technical characterictics below:
(1) the independent physics Cell ID (community ID) of TYPE II RELAY neither one;
(2) TYPE II RELAY is transparent to Rel-8UE;
(3) TYPE II RELAY improves the performance of Rel-8UE under the PDCCH of eNB covers
For Rel-8UE, only from eNB, receive PDCCH and CRS (Common Reference Signal, public reference signal);
Rel-8UE can receive data from the PDSCH (Physical Downlink Shared Channel, Physical Downlink Shared Channel) being strengthened by RN;
(4) TYPE II RELAY and eNB receive and dispatch by TDM (Time DivisionMultiplex, time division multiplexing) pattern in identical frequency band.
Current existing TYPE II RELAY technical scheme some problems below up existence:
(1) transmission that can only realize HARQ merges gain, and can not make full use of the repeater gain under the better condition of link condition and possible coding gain between RN and eNB;
(2), when RN carries out up HARQ merging transmission, in corresponding TTI (Transmission TimeInterval, Transmission Time Interval), RN can not receive the operation of the up new biography data of other UE, also can cause the hydraulic performance decline of RELAY;
(3) even if RN has correctly received the up TB of a UE, thereby UE still can carry out the waste that HARQ re-transmission causes upstream bandwidth;
What the HARQ of LTE adopted N passage stops waiting HARQ mechanism, the synchronous HARQ mechanism of the behavior of go up wherein, and TYPE II RELAY needs the up synchronous HARQ of compatible LTE machine-processed, realizes transparent to Rel-8UE.
In prior art,, mainly there is following problem in the uplink scheme for current Type II Relay:
Because Type II Relay is merely able to help to retransmit, therefore potential performance gain is limited;
Be similar to descendingly, the PDCCH information that RN need to separate a plurality of UE causes complexity to increase, and the PDCCH information of a plurality of UE exists higher probability of false detection simultaneously;
In technical scheme, how to assist Sounding RS signal to send not too clear and definite about RN at present, the impact that channel dependent scheduling performance of uplink is improved needs further research;
Due to RN sending and receiving, in the UL of eNB and DL frequency range, to carry out TDM multiplexing, and therefore, when UE retransmits (RN also retransmits), RN can not receive the upstream data of other UE, and this is by the availability of restricted T YPE II RELAY.

Embodiments of the invention provide a kind of ascending transmission method, are applied at least comprise that in the relay system of two transmitting uplink data passages, the method as shown in Figure 1, comprising:
Step s101, two transmitting uplink data passages obtain the configuration of base station;
Step s102, two transmitting uplink data passages are according to the configuration of base station, in the different uplink time intervals to intercepting and process from the upstream data of user terminal; For any system-frame, only have a transmitting uplink data passage to monitor the up new biography data of user terminal, another transmitting uplink data passage carries out mixed automatic retransfer to the upstream data of user terminal.
The embodiment of ascending transmission method in the present invention is described below in conjunction with a concrete application scenarios.
Corresponding LTE-TDD system, eNB carries out intercepting of upstream data by two RN by control signal or the configuration information of new definition on different UL TTI, and simultaneously each RN only participates in once retransmitting to guarantee that the up new biography data of all UE can be carried out reception & disposal by certain RN in 2 RN.In an application scenarios of the present invention, shown in Fig. 2, a RN carries out the monitoring of new biography in the system-frame of odd-numbered, carries out HARQ re-transmission in the system-frame of even-numbered; Another one RN carries out the monitoring of new biography in the system-frame of even-numbered, carries out HARQ re-transmission in the system-frame of odd-numbered.
The up TTI that eNB can send according to each RN carries out ascending resource distribution, and for RN is correctly received, eNB does not have the correct TB receiving to be transmitted to eNB by the wireless channel between RN and eNB.RN obtains after the re-transmission resource of eNB, by user's data being carried out with base-station transmission plane the form of tunnel encapsulation, to the up new biography data of eNB transparent transmission and uplink retransmission data, be about to data encapsulation corresponding to each UE and carry out transparent forwarding in the MAC of TB SDU.
In addition, RN measures the uplink detection signal Sounding RS of the UE monitoring, and the mode that channel quality is reported has two kinds:
1, setting threshold: if the channel quality of UE is better than the thresholding of regulation, RN notices this UE to eNB to the uplink channel information of RN by the control signal of new definition between own and eNB, eNB divides timing to the UE ascending resource of the UE set of GoodSounding RS, the channel information of noticing according to RN carries out up MCS (Modulation and Coding Scheme, Modulation and Coding Scheme) and selects.
2, periodically report: RN is according to the default cycle, the UE in periodic report service range and the channel quality of RN, the channel quality that eNB basis reports is that UE carries out up MCS selection.
The embodiment of the present invention in the application scenarios of new biography data retransmission, the signaling data interaction diagrams between UE, RN and eNB as shown in Figure 4, comprising:
Up Sounding RS of step 301:UE, being responsible for the RN that odd-numbered frame is monitored and even frame is monitored monitors Sounding RS respectively, if the channel quality between UE and RN is better than the thresholding of regulation or reports criterion according to the measurement of system regulation, RN notices this UE to eNB to the uplink channel information of RN by the control signal between own and eNB;
Step 302:RRC connects layoutprocedure (or reconfiguration course) by RRC to carry out Access Layer to UE and reshuffles (or reshuffling), if eNB does not need the configuration of RN and UE to change, does not need reconfiguration course; Carrying out ascending resource scheduling while determining MCS, the UE reporting according to RN and the channel information between RN are determined.
Step 303: for the up new biography data of UE, the RN1 that is responsible for monitoring at the corresponding up TTI of new biography transmission monitors and reception, demodulation buffer memory, eNB can receive this upstream data that UE sends simultaneously, if RN1 reception & disposal correctly, processes according to the following steps;
Step 304:eNB carries out demodulation to the data of receiving, if incorrect reception, by PHICH, feed back NACK (non-self-adapting HARQ re-transmission) or indicate re-transmission (adaptive HARQ re-transmission) by PDCCH, if correctly received, pass through PHICH feeding back ACK or indicate new biography by PDCCH; RN1 also can monitor the PDCCH of eNB and PHICH simultaneously, and the information of comprehensive PDCCH and PHICH transmission judges whether UE needs to carry out uplink retransmission, if do not need to retransmit, RN1 discharges the correct up TB of reception, otherwise carries out step process below;
Step 305: the RN1 that correctly receives new biography data retransmits up TTI (RN2 now monitors) and UE sends data together at the HARQ of UE, the signal that eNB sends RN1 and the UE picked up signal of decoding merges gain
The correct demodulating data of step 306:eNB, indicates eNB to receive successfully by PHICH.
In the application scenarios forwarding at data retransmission of the embodiment of the present invention, the signaling data interaction diagrams between UE, RN and eNB as shown in Figure 4, comprising:
Up Sounding RS of step 401:UE, being responsible for the RN that odd-numbered frame is monitored and even frame is monitored monitors Sounding RS respectively, if the channel quality between UE and RN is better than the thresholding of regulation or reports criterion according to the measurement of system regulation, RN notices this UE to eNB to the uplink channel information of RN by the control signal between own and eNB;
Step 402:RRC connects layoutprocedure (or reconfiguration course) by RRC to carry out Access Layer to UE and reshuffles (or reshuffling), if eNB does not need the configuration of RN and UE to change, does not need reconfiguration course; Carrying out ascending resource scheduling while determining MCS, the UE reporting according to RN and the channel information between RN are determined;
Step 403: for the up new biography data of UE, send at new biography RN1 that corresponding up TTI is responsible for monitoring and fail the correct data that receive UE, and eNB receives this upstream data that UE sends simultaneously;
Step 404:eNB carries out demodulation to the data of receiving, incorrect reception, by PHICH (Physical HARQ Indicator Channel, Physical HARQ Indicator Channel), feed back NACK (non-self-adapting HARQ re-transmission) or indicate re-transmission (adaptive HARQ re-transmission) by PDCCH;
Step 405:UE carries out HARQ re-transmission at next physical frame, and now RN2 is responsible for monitoring this HARQ data retransmission, and RN2 has successfully carried out acceptance, demodulation buffer memory to the HARQ data retransmission of UE
Step 406:eNB carries out demodulation to the HARQ data retransmission receiving, and correct reception, does not indicate eNB to take defeat by PHICH
Step 407:RN2 need to forward according to the information judgement of PHICH, by the data retransmission that is buffered in RN2 to eNB
The data that step 408:eNB forwards RN are carried out demodulation, success.By PHICH, indicate and receive successfully.
In the method providing in embodiments of the invention, base station indication RN monitors in some system frame number, some system frame number is carried out HARQ merging and business forwards, and makes 2 TYPE II RN collaborative work, guarantees that each up TTI can realize HARQ and merge gain and repeater gain.The RN of relative TYPEI, the TYPE II RN proposing in embodiments of the invention is fairly simple, is more suitable in network design; And eNB carries out resource distribution according to the channel condition between UE and RN, can not there is the waste of ascending wireless resource, can, under compatible existing standard and less control channel expense condition, can realize the forwarded upstream gain that approaches TYPE I RELAY.Finally, each up TTI can realize HARQ and merge gain and repeater gain, and because most of business uplink service can be configured to complete by 1 HARQ, so uplink time delay characteristic is relatively good.
