Description

Feedback method, terminal equipment and base station

Technical field

The present invention relates to the communications field, specifically, relate to a kind of feedback method, terminal equipment and base station.

Background technology

As time division duplex (TDD) pattern of one of two large basic duplex systems, at wide-band mobile communication under the ever-increasing background of bandwidth demand, receive increasing concern.In a tdd system, uplink and downlink transmission uses identical frequency resource, and different time slots transmits uplink/downlink signals.

In common TDD system, comprise TD SDMA (TD-SCDMA) system of 3G (Third Generation) Moblie (3G) system and time-division Long Term Evolution (TD-LTE) system of forth generation mobile communication (4G) system, wherein, the division of uplink and downlink time slot is static or semi-static, and common way divides according to cell type and business proportion determination uplink and downlink timeslot ratio roughly and remain unchanged in network planning process.This is comparatively simple way under the background of the large covering of macrocell, and also comparatively effective.

But, along with technical development, increasing Microcell (Pico cell), the low power base station such as Home eNodeB (Home NodeB) are deployed the little covering for providing local, in this kind of community, number of users is less, and customer service changes in demand is larger, therefore, there is situation about dynamically changing in the up-downgoing business proportion demand of community.Although also support the online uplink and downlink timeslot ratio changing community in such as TD-LTE standard, need comparatively complicated signaling process and setup time, cause systematic function to decline, real-time business situation of change can not be followed the tracks of.

And for traditional LTE TDD system, the TDD uplink/downlink configuration that operating carriers uses then notifies UE by system information (SystemInformationBlockType1), i.e. SIB1 configuration.For ensureing good backwards compatibility, supporting that dynamic TDD ascending-descending subframes distributes in the system of (the dynamic TDD of follow-up abbreviation) and still sending SIB1 configuration by system information.For not supporting the UE of dynamic TDD in system or not being configured to open the UE of dynamic TDD working method, be configured on this carrier wave according to SIB1 and work.And for supporting the UE of dynamic TDD, base station will send configuration information, dynamic TDD working method will be opened in instruction.Now, according to a descending reference configuration, UE will determine on this carrier wave, which subframe is descending sub frame, and the HARQ(Hybrid Automatic Repeat Request corresponding according to this reference configuration, hybrid automatic repeat-request) feed back determination/non-determined (ACK/NACK) information corresponding to sequential relationship transmission descending sub frame.Such as, the descending reference shown by table 1 is configured to TDD uplink/downlink configuration 5, during corresponding different SIB1 configuration, and HARQ feedback sequential relationship (i.e. descending sub frame set K).

Table 1. descending reference is configured to TDD uplink/downlink configuration 5, during corresponding different SIB1 configuration, and the value of set K, specific as follows:

Wherein, UE transmits ACK/NACK information corresponding to descending sub frame n-k in sub-frame of uplink n, k ∈ K, and adding black part number is then, when determining HARQ feedback sequential relationship according to SIB1 configuration, use the descending sub frame of sub-frame of uplink n transferring ACK/nack message.

In addition, for traditional LTE TDD system, LTE TDD system supports multiple ACK/NACK feedback system, such as, channel selection(Channel assignment), PUCCH format3(Physical Uplink Control Channel form 3) etc.Wherein, the benefit of Channel selection is to transmit the PUCCH(physical uplink control channel used) resource overhead is less, but its bearer cap is limited, can only feed back 4 bit informations at most.In addition, Channel selection can better utilize PUCCH implicit resource.And so-called PUCCH implicit resource, its resource number is according to the PDCCH/EPDCCH(Physical Downlink Control Channel/enhancement mode Physical Downlink Control Channel of schedule data transmission) the physical resource elements taken determine.The PUCCH implicit resource of respective numbers is reserved according to the expense of PDCCH/EPDCCH total in system in base station.System is for ensureing backwards compatibility, and this type of implicit resource must exist.The benefit of PUCCH format 3 is then be that bearer cap is large, and the PUCCH resource of its correspondence is by the explicit configuration in base station.

When practical application, in LTE Rel-8 system, when UE adopts channel selection mode (becoming the multiplexing multiplexing pattern of ACK/NACK in Rel-8 stage criterion) transferring ACK/NACK.For M the descending sub frame at same sub-frame of uplink transmitting feedback information, the ACK/NACK feedback information corresponding to the multiple code words (if being configured with many codeword transmission pattern) in each descending sub frame is merged (i.e. space merging by UE, spatial bundling), the discontinuous transmission of NACK/DTX(is produced to the descending sub frame not receiving data, Discontinues Transmission) as feedback information, after obtaining the ACK/NACK feedback information of M-bit, according to the corresponding relation of table 2 ~ 4, be numbered pUCCH resource on transmit b(0), b(1).Table 2 ~ 4 are specific as follows:

In table 2.LTE Rel-8 system, the ACK/NACK mapping form that M equals 2

Table 3 is in LTE Rel-8 system, the ACK/NACK mapping form that M equals 3

In table 4.LTE Rel-8 system, the ACK/NACK mapping form that M equals 4

And in LTE Rel-10 system, still support to use the mode of channel selection to transmit the ACK/NACK information of no more than 4 bits, and respectively define again 3 new ACK/NACK mapping forms, as shown in table 5 ~ 7.New form, compared with before, does not have overlap condition, and therefore performance is more excellent.Table 5 ~ 7 are specific as follows:

In table 5.LTE-A Rel-10 system, the ACK/NACK mapping form that M equals 2

In table 6.LTE-A Rel-10 system, the ACK/NACK mapping form that M equals 3

table 7.LTE-A in Rel-10 system, the ACK/NACK mapping form that M equals 4

But, in existing non-dynamic TDD system when UE configuration uses PUCCH format 3 transferring ACKs/nack message, DL DAI(downlink assignment index, descending distribution instruction) the TPC information field be greater than in the PDCCH/EPDCCH of 1 is used to indicate the resource of the PUCCH format 3 of transferring ACK/NACK feedback information.Now, the PDCCH/EPDCCH that UE only have received DL DAI>1 just uses PUCCH format 3 transmitting feedback information.And if UE only receives the PDCCH/EPDCCH of DLDAI=1, then can use PUCCH format1a/1b transmitting feedback information in PUCCH implicit resource.

And in existing dynamic TDD system, because UE is according to descending reference configuration effort, therefore, the descending sub frame receiving DL DAI=1 may not be the descending sub frame of SIB1 configuration correspondence, now, is there is not corresponding PUCCH implicit resource in system, therefore, PUCCH cannot be transmitted.Now, if directly increase proprietary information territory instruction PUCCH format 3 resource in PDCCH/EPDCCH, then descending control signaling expense can be increased, influential system efficiency.If always use TPC information field instruction PUCCH format 3 resource in PDCCH/EPDCCH, then UE can be caused cannot to know PUCCH transmitting power adjustment information timely.

For the above-mentioned situation in existing correlation technique, at present also for proposing effective solution.

Table 8 show descending reference configuration (namely first uplink/downlink configuration) for TDD uplink/downlink configure 5 time, when corresponding different SIB1 configures, the HARQ feedback sequential relationship of the set of first kind descending sub frame and the set of Equations of The Second Kind descending sub frame, specific as follows:

Table 8. according to the descending reference of the embodiment of the present invention be configured to TDD uplink/downlink configure 5 time, during corresponding different SIB1 configuration, the set of first kind descending sub frame and the set of Equations of The Second Kind descending sub frame

Wherein, be configured to TDD uplink/downlink configuration 1 when system information notice on carrier wave c, descending reference configuration (namely first uplink/downlink configuration) for TDD uplink/downlink configure 5 time, terminal equipment is at sub-frame of uplink n=2 transmission ACK/NACK feedback information, first descending sub frame set comprises descending sub frame { n-7, n-6} on carrier wave c, second descending sub frame set comprises descending sub frame { n-13, n-12, n-8 on carrier wave c, n-11, n-4, n-9, n-5}.Now, the behavior of UE feedback is as follows:

1) if { n-7, n-6} receive the PDCCH/EPDCCH of PDSCH and/or the release of instruction SPS resource to the descending sub frame of UE only on carrier wave c, then UE uses descending sub frame { the ACK/NACK information that n-7, n-6} are corresponding on the method transmission carrier wave c of channel selection;

2) if UE is descending sub frame { n-13, n-12, n-8 on carrier wave c, n-11, n-4, n-9, n-5} at least receives the PDCCH/EPDCCH of a scheduling PDSCH and/or the PDCCH/EPDCCH of instruction SPS resource release, then, in the PUCCH resource of UE TPC information field instruction in above-mentioned PDCCH/EPDCCH, use PUCCH format3 transmits descending sub frame { n-7, n-6} and { n-13 on carrier wave c, n-12, n-8, n-11, n-4, all ACK/NACK information corresponding in n-9, n-5};
