Description
Technical field
The present invention relates to communication technical field, the transmission method and the equipment of access link uplink feedback information under particularly a kind of carrier aggregation scene.
Background technology
LTE (Long Term Evolution, Long Term Evolution) system, it is the evolution system of 3-G (Generation Three mobile communication system), and LTE-Advanced (Long Term Evolution Advanced, senior Long Term Evolution) is the evolution system upgrading of 3-G (Generation Three mobile communication system), in the LTE-Advanced system, will adopt the service quality and the Extended Cell of the method raising Cell Edge User of RN (Relay Node, via node) cooperation transmission to cover.
Accordingly, defined the via node of following type:
1、Type?I?Relay
" Type 1 " Relay is the part of LTE-A at least." Type 1 " Relay is a Relay node in the band, has following feature:
RN controls the sub-district, and from the user, each sub-district is distinguished mutually with supplying with the sub-district, is an independently sub-district.
Each sub-district has the physical district ID (LTE Rel-8 defines) of increase, and RN can send synchronizing channel, the reference symbol of oneself.
Operation for single sub-district, UE (User Equipment, subscriber equipment) should be directly from RN receiving scheduling information and HARQ (Hybrid Automatic Repeat Request, mix automatic repeat requests) feedback, and the control channel of transmission UE is to RN, wherein, the control channel of UE comprises SR (SchedulingRequest, dispatch request)/CQI (Channel Quality Indicator, channel quality indication)/ACK (Acknowledge Character, acknowledge character).
Concerning Rel-8 (R8), RN seems to be exactly R8 eNB (evolved NodeB, the B node of evolution, i.e. base station).
For LTE-A UEs, Type 1 RN may seem different with R8 eNB, to allow further performance optimization.
2, link is divided
After the LTE-A system introduces via node, make that the Radio Link based on the mobile communication system of Relay has three, as shown in Figure 1:
Node wherein comprises:
Donor-eNB: with RN equipment the eNB of wireless connections is arranged, be abbreviated as DeNB;
Relay-Node: be present in the entity between DeNB and the UE, be abbreviated as RN equipment;
Relay-UE: the UE with RN equipment carries out data interaction is abbreviated as R-UE;
Grand UE: directly and the DeNB UE that carries out data interaction.
Interface comprises:
Un interface: the interface between RN equipment and the DeNB;
Interface between Uu interface: UE and the RN equipment.
Radio Link comprises:
Backhaul link: back haul link, with Un interface link corresponding;
Access link: access link, with Uu interface link corresponding;
Direct link: the direct projection link, DeNB and grand UE carry out the link of transfer of data.
Consider the signal interference-limited of radio communication, therefore, three links need use the Radio Resource of quadrature.Because the transceiver of via node is half TDD (Time Division Duplexing, time division duplex) mode of operation, the Backhaul link takies different time slots with the Access link in the tdd frame structure, but Direct link and Backhaul link are can be coexistent, as long as its running time-frequency resource quadrature.
3, transmission of TDD system descending and the timing of uplink ACK/NACK (Negative Acknowledgment, negative acknowledge character) feedback
On the Access link, PDSCH (Physical Downlink Shared Channel, Physical Downlink Shared Channel) transmission is identical with Rel-8 with the timing between uplink ACK/NACK, the ACK/NACK information that UE feeds back in sub-frame of uplink n is the testing result of PDSCH on the subframe n-k, k ∈ K wherein, the K value is as shown in table 1.
The descending relative set index of table 1:TDD K:{k
0, k
1... k
M-1}
4, the background context of carrier aggregation among the Rel-10
For the LTE-A system, for supporting the system bandwidth wideer,, need couple together use by resource with a plurality of LTE carrier waves (claiming member carrier again, Component Carrier, abbreviation CC) such as 100MHz than LTE system, dual mode is specifically arranged:
(1) a plurality of continuous LTE carrier waves is carried out polymerization, for the LTE-A system provides bigger transmission bandwidth;
(2) a plurality of discontinuous LTE carrier waves are carried out polymerization, for the LTE-A system provides bigger transmission bandwidth.
As shown in Figure 2, for carrier aggregation schematic diagram of the prior art, provided the example that discontinuous carrier wave carries out polymerization.At present, be that design on each carrier wave keeps consistent as far as possible with LTE Release 8 for the common recognition of carrier aggregation system design, thereby, the terminal of assurance LTE R8 can be on each member carrier operate as normal.
In the process that realizes the embodiment of the invention, the inventor finds that there is following problem at least in prior art:
According to above-mentioned table 1, for most TDD uplink-downlink configuration, on access link, R-UE need send the uplink ACK/NACK feedback of corresponding a plurality of PDSCH packets in a sub-frame of uplink.
If this sub-frame of uplink is configured to the back haul link sub-frame of uplink, because back haul link uses an identical carrier wave with access link, for fear of interference, RN can't receive uplink ACK/NACK feedback that R-UE sends in this subframe, PDSCH packet before RN can't judge whether receive correct by termination, need can't judge whether to retransmit, and then influence access link downlink transfer performance.
With TDD uplink-downlink configuration 2 is example, and as shown in Figure 3, according to table 1 predetermined timing relation, if RN sends the PDSCH packet on access link descending sub frame 4/5/6, R-UE sends corresponding uplink ACK/NACK feedback at sub-frame of uplink 2.If sub-frame of uplink 2 is configured to the back haul link sub-frame of uplink, then RN can't receive uplink ACK/NACK feedback.

Embodiment
As stated in the Background Art, in existing TDD system, the part sub-frame of uplink is configured to the back haul link sub-frame of uplink, be used for via node and send upstream data to home base station, and because in the Rel-10 standard, back haul link and access link are only supported a carrier wave, therefore, on access link, via node can't receive the uplink feedback information that the terminal equipment of its service reports in these subframes, influenced access link downlink transfer performance.
In follow-up Standard Edition, access link can be introduced the polymerization ZAP, promptly support multi-carrier transmission, the problem that the technical scheme that the embodiment of the invention proposed will solve is exactly that problem is lost in the uplink feedback information transmission that utilizes multi-transceiver technology to solve access link.
As shown in Figure 4, the schematic flow sheet of the transmission method of access link uplink feedback information under a kind of carrier aggregation scene that provides for the embodiment of the invention, this method specifically may further comprise the steps:
Step S401, via node are on access link, and the member carrier by each polymerization is initiated different transmission processes to terminal equipment, and configurating terminal device carries out uplink feedback information and transmits applied main member carrier in different transmission processes.
Step S402, via node pass through the different main member carrier that disposed in different transmission processes, the uplink feedback information of receiving terminal apparatus transmission.
In concrete transmission course, in the applied system of said method, except access link, can also comprise back haul link, therefore, comprise following back haul link transmission course equally, promptly the different back haul link subframes that disposed on via node and the member carrier of base station by polymerization are carried out the back haul link message transmission;
Under the scene that comprises the back haul link transmission, the subframe that is used to transmit uplink feedback information that the pairing member carrier of main member carrier that is disposed among the above-mentioned step S401 is disposed on access link, the back haul link subframe that is disposed on back haul link with the pairing member carrier of this main member carrier is different.
Further, the process to via node carries out main member carrier configuration according to the sub-frame configuration of member carrier in the back haul link specifies as follows:
Via node receives after the different back haul link subframe transmission information that the base station disposed on the member carrier of polymerization, discerns the back haul link subframe that is disposed on the member carrier of each polymerization;
When the relaying node is initiated the transmission process on access link, in the pairing a plurality of member carriers of transmission process, select the main member carrier of a member carrier, and carry out the transmission of access link uplink feedback information in the subframe different with the back haul link subframe that on back haul link, is disposed certainly by main member carrier as corresponding transmission process.
In the application scenarios of reality, may there be following two kinds of situations in the carrier wave configuration for back haul link:
The different back haul link subframes that disposed on situation one, via node and the member carrier of base station by a plurality of polymerizations are carried out the back haul link message transmission.
Promptly in back haul link, a plurality of member carriers carry out the message transmission of back haul link by different back haul link sub-frame configuration and via node, are independent of each other between the transmission course of each member carrier.
The back haul link message transmission is only carried out by the back haul link subframe that is disposed on the member carrier in situation two, via node and base station.
In such cases, to have only on the member carrier to have the back haul link sub-frame configuration, the base station also only can send the backhaul link information to via node on this member carrier, and other member carriers then do not participate in the message transmission in the back haul link.
It is pointed out that above-mentioned situation two can be considered as a kind of special circumstances of situation one, promptly only on a member carrier, disposed the back haul link subframe, and the back haul link subframe that other member carriers are configured is sky.
In actual applications, specifically using which kind of above-mentioned situation carries out the configuration of back haul link and can't influence protection scope of the present invention.
Based on above-mentioned explanation, for situation one, can carry out the configuration of the main member carrier of access link according to aforesaid scheme, only need to guarantee to be configured to the member carrier of main member carrier, in access link and back haul link shared transmission subframe mutually conflict get final product.
And for situation two, corresponding processing procedure can be directly for via node in the member carrier except that the member carrier that has disposed the back haul link subframe, selects a member carrier conduct main member carrier of transmission process accordingly.By such configuration, the member carrier that guarantees to carry out the back haul link message transmission in the selected main member carrier of access link and back haul link is different, thereby, can directly avoid the conflict of shared sub-frame resources.
Accordingly, corresponding above-mentioned processing method, in base station and terminal equipment side, all need to adjust accordingly, wherein, base station side and terminal equipment side all need to support multi-carrier polymerizing, simultaneously, terminal equipment is according to the indication of via node, on the one hand, set up different transmission processes by the member carrier and the via node of a plurality of polymerizations, on the other hand, same configuration according to via node, in described different transmission process, determine to carry out uplink feedback information and transmit applied main member carrier, then, in different transmission processes, by the different main member carrier of determining, send uplink feedback information to via node.
Compared with prior art, the embodiment of the invention has the following advantages:
By using the technical scheme that the embodiment of the invention proposed, utilize carrier aggregation technology, in access link, select different member carriers to transmit the transmission of the uplink feedback information of process accordingly as main member carrier, thereby, can be according to concrete transmission process, selection can be carried out the member carrier of uplink feedback information normal transmission as main member carrier, avoid guaranteeing the normal transmission of the uplink feedback information on the access link owing to conflict the mutually situation of the transmission information dropout that causes of access link and other links shared sub-frame resources on identical member carrier.
Below, the application scenarios in conjunction with concrete is elaborated to the technical scheme that the embodiment of the invention proposed.
The embodiment of the invention has provided a kind of multicarrier that utilizes and has solved the scheme that problem is lost in the transmission of access link uplink feedback information, as shown in Figure 5, structural representation for the concrete application scenarios of the transmission method of access link uplink feedback information under a kind of carrier aggregation scene that the embodiment of the invention proposed, it is the deployment scheme of a kind of multicarrier Relay, in this scene, DeNB, RN and R-UE all have the ability of supporting carrier aggregation, back haul link and access link are all supported two member carrier (Component Carrier, member carrier), i.e. CC1 shown in the figure and CC2.CC1 and CC2 be inter-band (interband) carrier wave or have enough duplexing isolations, when on two member carriers, transmitting simultaneously, and can the phase mutual interference.
Corresponding aforesaid situation one and situation two, in the description of follow-up concrete application process, the embodiment of the invention is considered following two kinds of scenes respectively, and corresponding processing procedure is described:
Scene one: back haul link all disposes the back haul link subframe on carrier wave CC1 and CC2
Suppose that pairing back haul link transmission of via node in this application scenarios and access link transmit and all on CC1 and CC2, carry out simultaneously.
At first, DeNB disposes different back haul link subframes on different carrier, RN is at the descending HARQ of difference (Hybrid Automatic Repeat reQuest, mix automatic repeat requests) different PCC (the Primary Component Carrier of configuration on the process, main member carrier), R-UE then transmits the uplink feedback information (being CC1ACK/NACK and CC2 ACK/NACK) of CC1 PDSCH and CC2P DSCH correspondence by corresponding PCC, make RN can receive CC1 ACK/NACK and CC2 ACK/NACK, avoided the uplink feedback information on access link to lose.
Below, be that example illustrates above-mentioned technical scheme with a kind of ascending-descending subframes allocation plan in the TDD system:
As shown in Figure 6, be the schematic diagram of the concrete transmission plan of the transmission method of access link uplink feedback information under a kind of carrier aggregation scene that the embodiment of the invention proposed.
DeNB is provided with different back haul link sub-frame configuration schemes on CC1 and CC2 (i.e. DeNB@CC1 shown in the figure and DeNB@CC2), particularly, on CC1, descending sub frame 4 and 8 and sub-frame of uplink 2 be the back haul link subframe; On CC2, descending sub frame 3 and 9 and sub-frame of uplink 7 be the back haul link subframe.
Accordingly, on access link, if RN sends PDSCH to R-UE in descending sub frame 4,5,6,8, then R-UE need transmit corresponding uplink feedback information in sub-frame of uplink 2; If RN sends PDSCH to R-UE in descending sub frame 0,1,3,9, then R-UE need transmit corresponding uplink feedback information in sub-frame of uplink 7.
Lose for fear of uplink feedback information, for descending sub frame 4,5,6,8 pairing descending HARQ processes, R-UE configuration CC2 is the PCC of this descending HARQ process, is used to transmit with descending sub frame 4,5,6,8 interior CC1 and CC2 go up the pairing uplink feedback information of PDSCH of transmission; And for descending sub frame 0,1,3,9 pairing descending HARQ processes, R-UE configuration CC1 is the PCC of this descending HARQ process, is used to transmit with descending sub frame 0,1,3,9 interior CC1 and CC2 go up the pairing uplink feedback information of PDSCH of transmission.
According to the description of top allocation plan as can be seen, on access link, when the transmission position of the uplink feedback information of PDSCH correspondence is the sub-frame of uplink of back haul link, R-UE is PCC by the configuration carrier wave different with back haul link, and on this PCC, send CC1 ACK/NACK and CC2 ACK/NACK, avoided interference, therefore to the back haul link uplink, RN can receive uplink feedback information, has avoided losing of uplink feedback information.
Scene two: back haul link is only gone up configuration back haul link subframe at carrier wave CC1 (or CC2)
Suppose that the pairing back haul link of via node in this application scenarios only disposes the back haul link subframe on CC1, the up-downgoing transmission of this back haul link is all carried out on CC1.
In this technical scheme, RN directly is configured to CC2 to transmit accordingly the PCC of process, R-UE transmits the uplink feedback information (being CC1ACK/NACK and CC2 ACK/NACK) of CC1 PDSCH and CC2PDSCH correspondence on CC2, make RN can receive CC1 ACK/NACK and CC2 ACK/NACK, avoided the uplink feedback information on access link to lose.
Below, be that example illustrates above-mentioned technical scheme with a kind of ascending-descending subframes allocation plan in the TDD system:
As shown in Figure 7, be the schematic diagram of the concrete transmission plan of the transmission method of access link uplink feedback information under a kind of carrier aggregation scene that the embodiment of the invention proposed.
DeNB on CC1 configurating downlink subframe 4 and 8 and sub-frame of uplink 2 be the back haul link subframe.At access link.
In corresponding transmission process, RN directly is configured to PCC with carrier wave CC2, when RN descending sub frame 0,1,3,9 in CC1 and CC2 on send PDSCH to R-UE, the pairing uplink feedback information of transmission PDSCH on the CC2 of R-UE in the sub-frame of uplink 7 of correspondence; When RN in descending sub frame 5,6 CC1 and CC2 on send PDSCH to R-UE, the pairing uplink feedback information of transmission PDSCH on the carrier wave CC2 of R-UE the sub-frame of uplink 2 of correspondence in.
By last analysis as can be seen, though sub-frame of uplink 2 is the back haul link sub-frame of uplink, but owing to use CC1 to transmit on the back haul link, and use CC2 to transmit on the access link, both transmission carrier wave differences, therefore, corresponding ascending resource can not clash, RN can receive the CC1 ACK/NACK that CC2 goes up transmission, has avoided losing of uplink feedback information.
