Description

A kind of method of transmitting feedback information, equipment and system

Technical field

The present invention relates to communication technical field, particularly a kind of method of transmitting feedback information, equipment and system.

Background technology

Multi-point cooperative transmission (Coordinated Multipoint Transmission/Reception, CoMP) technology refers to the cooperation transmission between the multiple transfer points that separate on geographical position.In general, the plurality of transfer point can be the base station of different districts, can be also multiple remote radio-frequency heads (Remote Radio Head, RRH) of the base station control of same community.By the cooperation transmission between multiple transfer points, can effectively reduce the interference between different transfer points, improve the particularly throughput of Cell Edge User equipment of subscriber equipment (User Equipment, UE).According to the difference of up/down row transmission, CoMP technology is divided into up CoMP transmission and descending CoMP transmission, and wherein, up CoMP transmission mainly comprises cooperative scheduling and combines reception two schemes.

Wherein, combine the signal demand that receives the same UE that refers to that multiple transfer points receive by Combined Treatment to obtain output signal.Typical way is as follows: each cooperative base station is according to the testing result of self, by the positive acknowledgement (Acknowledgement corresponding to data of same UE transmission, ACK)/Negative Acknowledgement (Negative Acknowledgement, NACK) feedback information is given the serving BS of this UE alternately, the ACK/NACK information of serving BS comprehensive self and each cooperative base station judges whether to need UE to retransmit, again the ACK/NACK information after comprehensive to UE(is for example notified, by Physical HARQ Indicator Channel (Physical HARQ Indicator Channel, PHICH; Hybrid Automatic Repeat reQuest, HARQ) or the notice such as ePHICH to UE), as long as had base station correct receive and demodulation the upstream data of this UE (not necessarily serving BS), notify ACK; If the base station of the cooperative transmission of all these UE of participation does not all have the upstream data of correct reception or correct this UE of demodulation, notify NACK; So that UE judges whether to need to retransmit accordingly.

The time delay of carrying out information interaction between base station is at present generally more than 10ms, owing to will notifying UT to retransmit or dispatch new upstream data after completing information interaction between base station, increase largely the propagation delay time of UE side upstream data, thereby had a strong impact on the uplink efficiency of UE.Therefore, proposed a kind of uplink ACK/nack message based on UE feedback and carried out mutual scheme, concrete:

The each base station that participates in the cooperative transmission of this UE is notified respectively to UE detecting separately the ACK/NACK information for same upstream data (being called for short uplink ACK/nack message) obtaining; This UE, according to the uplink ACK/nack message of each base station notice, judges whether to retransmit this upstream data, to the uplink ACK/nack message receiving is merged to processing, and will merge uplink ACK/nack message after treatment and feed back to each base station; Each base station determines according to merging uplink ACK/nack message after treatment whether UE can carry out the re-transmission of this upstream data, and judges whether to carry out information interaction and the follow-up scheduling between base station.Enumerate two kinds of UE below and the uplink ACK/nack message receiving is merged to the method for processing, but merge the following side's method that is not limited to of processing.

1, each uplink ACK/nack message is carried out to logic OR processing and obtain the uplink ACK/nack message after 1 bit merges.For example, in the time that the uplink ACK/nack message that has a base station at least is ACK, amalgamation result is ACK; In the time that the uplink ACK/nack message of all base stations is all NACK, amalgamation result is NACK.

2,, according to predefined corresponding relation, determine that K(K is positive integer) bit information is as the uplink ACK/nack message after merging, the various combination relation of the uplink ACK/nack message of the corresponding each base station of the different conditions of this K bit information.Illustrate, the cooperative transmission that participates in this UE taking three base stations is as example, now K=2, corresponding relation between the various combination relation of the different conditions of this 2 bit information and the uplink ACK/nack message of each base station can be as shown in table 1, wherein, suppose that " 1 " in instruction content represents ACK, " 0 " represents NACK, certainly, this corresponding relation also can adopt other modes to represent.

K bit information	Instruction content
		00	The ACK/NACK information of each base station notice is respectively 000 or 111

01	The ACK/NACK information of each base station notice is respectively 001 or 110
		10	The ACK/NACK information of each base station notice is respectively 100 or 011
11	The ACK/NACK information of each base station notice is respectively 010 or 101

Table 1

But, the current specific implementation of also not transmitting the uplink ACK/nack message after merging.

Embodiment

The embodiment of the present invention provides a kind of method, equipment and system of transmitting feedback information, for solving the UE of up employing CoMP transmission, in the time receiving being used to indicate the first feedback information that whether same upstream data correctly receive and obtaining the second feedback information for indicating this same upstream data whether to need to retransmit to base station based on the first feedback information of base station feedback of multiple participations cooperation, how to the problem of base station feedback the second feedback information.The embodiment of the present invention comprises two kinds of situations, and one is individual transmission the second feedback information, and another kind is that the ACK/NACK feedback information of the second feedback information and downlink data transmits simultaneously.

Below in conjunction with Figure of description, the embodiment of the present invention is described in further detail.

A kind of method that sends feedback information shown in Figure 1, the embodiment of the present invention provides, comprises the following steps:

Step 11, the feedback sequential relationship that UE is corresponding according to the second feedback information, determine second feedback information that need to feed back in sub-frame of uplink n;

Wherein, whether second feedback information the second feedback information is used to indicate described UE and can retransmits participating in the same upstream data that each base station of cooperative transmission of this UE receives, and this second feedback information comprises M ₁the second feedback information corresponding to each descending sub frame in individual descending sub frame, the second feedback information that each descending sub frame is corresponding is that basis is at M ₁the first feedback information of the base station feedback of the cooperative transmission of each this UE of participation receiving in the each descending sub frame in individual descending sub frame obtains; Whether the base station that the first feedback information is used to indicate the cooperative transmission that participates in this UE correctly receives the same upstream data that this UE sends; M ₁individual descending sub frame is according to feedback sequential relationship corresponding to the second feedback information descending sub frame that determine and need to feed back the second feedback information in sub-frame of uplink n; N is subframe numbering, and n is natural number.

In the embodiment of the present invention, the base station that participates in the cooperative transmission of this UE comprises serving BS and at least one cooperative base station of this UE;

In this step, the feedback sequential relationship that UE is corresponding according to the second feedback information, first determines that the descending sub frame that need to feed back the second feedback information in sub-frame of uplink n (is designated as M ₁individual descending sub frame); Then, according to this M ₁the first feedback information of the base station feedback of the cooperative transmission of each this UE of participation receiving in the each subframe in individual descending sub frame, determines the second feedback information that each descending sub frame is corresponding; Finally by this M ₁the second feedback information level corresponding to each descending sub frame in individual descending sub frame is linked togather and obtains second feedback information that need to feed back in this sub-frame of uplink n.

Preferably, the second feedback information is the ACK/NACK information of upstream data, for whether needing the received same upstream data in base station of the cooperative transmission to participating in this UE to retransmit to base station instruction UE, can make base station obtain other reception condition of the base station that participates in cooperative transmission to this same upstream data.

Step 12, UE, in this sub-frame of uplink n, send by PUCCH and/or PUSCH the second feedback information of determining.

Further, before step 12, the method also comprises:

Step 13, the feedback sequential relationship that UE is corresponding according to the 3rd feedback information, determine the 3rd feedback information that need to feed back in this sub-frame of uplink n;

Wherein, the 3rd feedback information comprises M ₂the 3rd feedback information corresponding to each descending sub frame in individual descending sub frame, whether the downlink data that the 3rd feedback information that each descending sub frame is corresponding is used to indicate in this descending sub frame correctly receives, M ₂individual descending sub frame is according to feedback sequential relationship corresponding to the 3rd feedback information descending sub frame that determine and need to feed back the 3rd feedback information in sub-frame of uplink n.

Accordingly, step 12 further comprises:

Step 12a, UE, in sub-frame of uplink n, send the second feedback information and the 3rd feedback information by PUCCH and/or PUSCH simultaneously.

It should be noted that, in step 13, the feedback sequential relationship that UE is corresponding according to the 3rd feedback information, first determines that the descending sub frame that need to feed back the 3rd feedback information in this sub-frame of uplink n (is designated as M ₂individual descending sub frame); Then, according to from this M ₂in each descending sub frame in individual descending sub frame, receive the situation (whether can correctly receive this downlink data) of the downlink data of the base station transmission of the cooperative transmission of each this UE of participation, determine this M ₂the 3rd feedback information corresponding to each descending sub frame in individual descending sub frame.

Preferably, the ACK/NACK information that the 3rd feedback information is downlink data.

In the embodiment of the present invention, before step 11, the method also comprises:

Schedule information or cycle configuration information that UE sends according to self serving BS, carry out transmitting uplink data.

Accordingly, correctly whether the same upstream data that each base station (comprising the serving BS of this UE and all cooperative base station) sends according to this UE transmission, obtains corresponding the first feedback information, and feeds back to UE; Concrete:

If this base station can correctly receive the same upstream data that this UE sends, the content of the first feedback information that this base station obtains is ACK, and sends this first feedback information to UE; And

If this base station can not correctly receive this upstream data, the content of the first feedback information that this base station obtains is NACK, and sends this first feedback information to UE.

Schedule information or cycle configuration information that UE sends according to base station, downlink data receiving.

Preferably, in step 11, second feedback information that need to send in sub-frame of uplink n that UE determines comprises A bit information.

Preferably, A=1 or A=2.

It should be noted that, if the second feedback information is ACK/NACK information, second feedback information that need to send in sub-frame of uplink n that UE determines is also referred to as the ACK/NACK information of pretreated upstream data, and the ACK/NACK information of this pretreated upstream data is: UE basis is at each descending sub frame in the ACK/NACK information that obtains of the ACK/NACK information (i.e. the first feedback information) of the same upstream data of correspondence of base station feedback of cooperative transmission of each this UE of participation of receiving, wherein, and for correspondence is closed the descending sub frame index of set of the ACK/NACK information of pretreated upstream data, i.e. said M in step 11 in sub-frame of uplink n to base station feedback ₁individual descending sub frame.Wherein, UE determines that according to the first feedback information receiving the concrete grammar of the second feedback information can be: if the content of the first feedback information of the same upstream data of correspondence that at least one base station is returned is ACK, or the current number of retransmissions of this UE has reached maximum retransmission, this UE determines the re-transmission that does not need to carry out upstream data, and producing ACK does not need to retransmit to this same upstream data for informing base station UE as the second feedback information; Otherwise, that is: the content of the first feedback information that each base station is returned is NACK and the current number of retransmissions of this UE is less than maximum retransmission, this UE determines need to carry out the re-transmission of upstream data, produces NACK and need to retransmit this same upstream data for informing base station UE as the second feedback information.

Further, in step 11, the feedback sequential relationship that the second feedback information is corresponding is configured to UE by high-level signaling by network side; Or made an appointment with each base station respectively by UE; Or be the feedback sequential relationship (even descending sub frame n-k is cooperative base station is carried out descending sub frame from the ACK/NACK information (i.e. the first feedback information) of the upstream data of cooperative transmission to UE feedback, and this UE feeds back in the definite corresponding sub-frame of uplink of sequential and transmits to the ACK/NACK of ACK/NACK information (i.e. the second feedback information) downlink data according to this descending sub frame of the pretreated upstream data of base station feedback) of the 3rd feedback information of 3GPP agreement regulation.

It should be noted that, which kind of feedback sequential relationship UE specifically adopts in agreement, to specify, after also can being determined by UE, notice, to each base station, can also be determined by UE and base station negotiate, but must ensure that UE is consistent with the understanding of base station.

Further, before step 12, the method also comprises:

Step 14, UE judge whether in sub-frame of uplink n, to feed back the 3rd feedback information;

If the determination result is YES (for example, UE is at this M ₂in at least one descending sub frame in individual descending sub frame, receive downlink data), UE execution step 13 and step 12a;

For example, if judged result is that no (, UE is at this M ₂in any one descending sub frame in individual descending sub frame, all do not receive downlink data, this situation further comprises following two kinds of possibilities: the one, and downlink transfer has been carried out in base station, but there is packet loss in UE; The 2nd, base station is at M ₂in individual descending sub frame, do not transmit any downlink data that need to feed back the 3rd feedback information to this UE), step 12 further comprises:

Step 12b, this UE, in sub-frame of uplink n, only send the second definite feedback information by PUCCH or PUSCH.

Further, step 12b comprises:

This UE, in this sub-frame of uplink n, sends second feedback information on the PUCCH channel resource obtaining at the pre-configured PUCCH channel resource of high-level signaling or according to PDCCH/EPDCCH; Or, on PUSCH, send the second feedback information by punching mapping mode.

Preferably, on the PUCCH channel resource obtaining at the pre-configured PUCCH channel resource of high-level signaling or according to PDCCH/EPDCCH, sending the second feedback information is applicable to: in sub-frame of uplink n, transmit without PUSCH; Or have PUSCH transmission in sub-frame of uplink n, and while supporting that PUCCH and PUSCH transmit simultaneously; On PUSCH, send the second feedback information and be applicable to by punching mapping mode: in sub-frame of uplink n, there is PUSCH transmission, or when having PUSCH transmission in sub-frame of uplink n and not supporting that PUCCH and PUSCH transmit simultaneously.

Further, UE in sub-frame of uplink n, the one in the following ways, the PUCCH channel resource obtaining by the pre-configured PUCCH channel resource of high-level signaling or according to PDCCH/EPDCCH sends the second feedback information:

Mode 1, in the time that the bit number of the second feedback information is no more than 2 bit, UE, on PUCCH format1a/1b channel resource, adopts PUCCH format1a/1b scheme to send the second feedback information; Particularly, in the time that the bit number of the second feedback information is 1 bit, adopt PUCCH format1a scheme, in the time that the bit number of the second feedback information is 2 bit, adopt PUCCH format1b scheme;

Wherein, in the time of PUCCH channel resource that UE obtains according to PDCCH/EPDCCH, concrete mode is as follows:

When receiving PDSCH or indicating downlink semi-continuous scheduling (the Semi-Persistent Scheduling of corresponding PDCCH/EPDCCH on the carrier wave that UE is configuring, SPS) resource discharge PDCCH/EPDCCH time, the PUCCH format1a/1b channel resource that PUCCH format1a/1b scheme adopts can be determined (in the time adopting single antenna port transmission according to the minimum control channel unit CCE/eCCE numbering of the PDCCH/EPDCCH receiving, only determine 1 resource, in the time adopting 2 antenna port transmission, determine 2 resources according to minimum CCE and minimum CCE+1 numbering, corresponding each antenna port respectively), in the time that this UE receives the SPSPDSCH that there is no corresponding PDCCH/EPDCCH on the carrier wave of configuration, the PUCCH format1a/1b channel resource that PUCCH format1a/1b scheme adopts is to be used to indicate the pre-configured channel resource of the indicated high-level signaling in transmitting power control TPC territory in the PDCCH/EPDCCH of this SPS PDSCH resource active (in the time adopting single antenna port transmission, the channel resource of this TPC instruction is 1 resource, in the time adopting 2 antenna port transmission, the channel resource of this TPC instruction comprises 2 resources, corresponding each antenna port respectively).

Mode 2, in the time that the bit number of the second feedback information is no more than 4 bit, UE adopts that to select with channel the PUCCH form 1b(combining be PUCCH format1b with channel selection) scheme sends the second feedback information; Specifically comprise:

UE transmits according to PUCCH format1b with channel selection the ACK/NACK mapping form that the feedback information of the bit length of the second feedback information uses, determine channel resource and transmitted bit b0b1 that the second feedback information is corresponding, on definite channel resource, adopt PUCCH format1b to transmit definite transmitted bit b0b1;

Preferably, the PUCCH format1b channel resource that the needed participation channel of PUCCH format1b with channel selection is selected is that high-level signaling is pre-configured;

For example, in the time that the second feedback information is 2 bit, be assumed to be [ACK, NACK], transmit according to PUCCHformat1b with channel selection the ACK/NACK mapping form (mapping form that example is as shown in table 2) that 2 bit feedback information are used, determine that the corresponding channel resource of the second feedback information [ACK, NACK] of this 2 bit is for being numbered channel resource, transmitted bit b0b1 is " 0,1 ", is being numbered pUCCH format1b channel resource on adopt PUCCH format1b scheme to transmit the transmitted bit " 0,1 " of 2 bits, for representing 2 bit the second feedback informations; Wherein, when table 2 is descending ACK/NACK information use PUCCH Format1b with channel selection, M ₂=2 ACK/NACK mapping form.

Table 2

Mode 3, UE adopt PUCCH format3 scheme to send the second feedback information;

Preferably, the PUCCH format3 channel resource that PUCCH format3 scheme is used for high-level signaling pre-configured.

Further, in step 12a, UE, in sub-frame of uplink n, sends the second feedback information and the 3rd feedback information by PUCCH and/or PUSCH simultaneously, specifically comprises the one in following method:

Method 1, UE send the second feedback information and the 3rd feedback information by PUCCH simultaneously;

Preferably, method 1 is applicable to: in sub-frame of uplink n, do not have PUSCH transmission; Or in sub-frame of uplink n, have PUSCH transmission, and this UE supports PUCCH and PUSCH transmission simultaneously in same sub-frame of uplink.

If there is PUSCH transmission in method 2 sub-frame of uplink n, UE sends the second feedback information and the 3rd feedback information by PUSCH simultaneously;

Preferably, method 2 is applicable to: in sub-frame of uplink n, have PUSCH transmission, and this UE does not support PUCCH and PUSCH transmission simultaneously in same sub-frame of uplink; Or in sub-frame of uplink n, have PUSCH transmission, and this UE supports PUCCH and PUSCH transmission simultaneously in same sub-frame of uplink.

If there is PUSCH transmission in method 3 sub-frame of uplink n, and this UE supports PUCCH and PUSCH transmission simultaneously in same sub-frame of uplink; UE sends the second feedback information by PUCCH, and sends the 3rd feedback information by PUSCH; Or UE sends the second feedback information by PUSCH, and send the 3rd feedback information by PUCCH.

It should be noted that, if there is PUSCH transmission in sub-frame of uplink n, and this UE supports PUCCH and PUSCH transmission simultaneously in same sub-frame of uplink, method for optimizing 3; If there is PUSCH transmission in sub-frame of uplink n, and this UE does not support PUCCH and PUSCH transmission simultaneously in same sub-frame of uplink, method for optimizing 2; If there is not PUSCH transmission in sub-frame of uplink n, only can adopt method 1.

In the embodiment of the present invention, method 2 specifically comprises:

The second feedback information and the 3rd feedback information are carried out cascade processing by UE, and information after treatment cascade be mapped in the respective resources of this PUSCH and send.

Further, the second feedback information and the 3rd feedback information are carried out cascade processing by UE, further comprises:

After the second feedback information level is associated in the 3rd feedback information by UE; Or

After the 3rd feedback information level is associated in the second feedback information by UE.

It should be noted that specifically adopt which kind of cascade processing mode to be specified by agreement, after also can UE determining, notice, to each base station, can also be consulted to determine with UE by base station, but must guarantee base station consistent with the understanding of UE.

Preferably, UE is mapped to information after treatment cascade in the respective resources of PUSCH, specifically comprises:

UE crosses punching mapping mode by information exchange after treatment cascade and is mapped in the corresponding resource of PUSCH.

In the embodiment of the present invention, method 1, further comprises following three kinds of modes:

Mode A, UE adopt PUCCH format1b scheme to send the 2 bit feedback information that are made up of the second feedback information and the 3rd feedback information cascade simultaneously;

When UE receives at least two transmission blocks (Transport Block in a descending sub frame, TB) time, this UE produces 1 bit ACK/nack message to the each TB in this descending sub frame, ACK/NACK information corresponding all TB in this descending sub frame is merged to processing, and the 1 bit ACK/nack message obtaining is as the 3rd feedback information corresponding to this descending sub frame after merging processing;

Wherein, the second feedback information and the 3rd feedback information include 1 bit information, the channel resource that the channel resource acquisition methods that the channel resource that PUCCH format1b uses adopts while being employing PUCCH format1b scheme transmission the 3rd feedback information specifying according to 3GPP agreement obtains, or be the pre-configured channel resource of high-level signaling;

This channel resource acquisition methods is concrete:

In the time that UE receives the PDSCH of corresponding PDCCH/EPDCCH or the PDCCH/EPDCCH of indicating downlink SPS resource release on the carrier wave of configuration, the PUCCH format1b channel resource that PUCCH format1b scheme adopts can be determined (in the time adopting single antenna port transmission according to the minimum control channel unit CCE/eCCE numbering of the PDCCH/EPDCCH receiving, only determine 1 resource, in the time adopting 2 antenna port transmission, determine 2 resources according to minimum CCE and minimum CCE+1 numbering, corresponding each antenna port respectively), when this UE receives while thering is no the SPS of corresponding PDCCH/EPDCCH PDSCH on the carrier wave of configuration, the PUCCHformat1b channel resource that PUCCH format1b scheme adopts is to be used to indicate the pre-configured channel resource of the indicated high-level signaling in transmitting power control TPC territory in the PDCCH/EPDCCH of this SPS PDSCH resource active (in the time adopting single antenna port transmission, the channel resource of this TPC instruction is 1 resource, in the time adopting 2 antenna port transmission, the channel resource of this TPC instruction comprises 2 resources, corresponding each antenna port respectively).
