Description

Feedback method, terminal device and base station

Technical field

The present invention relates to the communications field, it particularly relates to a kind of feedback method, terminal device and base station.

Background technology

Time division duplex as one of two big basic duplex systems（TDD）Pattern, in wide-band mobile communication to bandwidth demand It is of increased attention under ever-increasing background.In a tdd system, uplink and downlink transmission uses identical frequency Rate resource transmits uplink/downlink signals on different time slots.

In common TDD system, including 3G (Third Generation) Moblie（3G）The TD SDMA of system（TD- SCDMA）System and forth generation mobile communication（4G）The time-division Long Term Evolution of system（TD-LTE）System, wherein, uplink and downlink The division of time slot is static or semi-static, it is common practice to the industry in network planning process according to cell type and substantially Business ratio-dependent uplink and downlink timeslot ratio is divided and remained unchanged.This is relatively simple do under the background of the big covering of macrocell Method, and also more effectively.

However, as technology develops, more and more Microcells (Pico cell), Home eNodeB (Home NodeB) etc. Low power base station is by disposing for providing local small covering, and in this kind of cell, number of users is less, and customer service demand It changes greatly, therefore, the uplink and downlink business proportion demand of cell has that dynamic changes.Although in such as TD-LTE standards In also support the online uplink and downlink timeslot ratio for changing cell, but need more complicated signaling process and setup time, cause System performance declines, and can not track real-time business situation of change.

And for traditional LTE TDD systems, the TDD uplink/downlink configuration used on operating carriers is then by system information （SystemInformationBlockType1）Notify UE, i.e. SIB1 configurations.To ensure good backwards compatibility, support Dynamic TDD ascending-descending subframes distribute（Follow-up abbreviation dynamic TDD）System in still pass through system information send SIB1 configuration.It is right It does not support the UE of dynamic TDD in system or is not configured to open the UE of dynamic TDD working methods, configured according to SIB1 in the load It works on ripple.And for supporting the UE of dynamic TDD, base station will send configuration information, and dynamic TDD working methods are opened in instruction.This When, UE will determine which subframe is downlink subframe on the carrier wave according to a descending reference configuration, and according to the reference configuration pair The HARQ answered（Hybrid Automatic Repeat Request, hybrid automatic repeat-request）It feeds back under sequential relationship transmission Row subframe is corresponding definite/non-determined（ACK/NACK）Information.For example, the descending reference shown by table 1 is configured to TDD up/down Row configuration 5, when corresponding different SIB1 are configured, HARQ feedback sequential relationship（That is downlink subframe set K）.

1. descending reference of table is configured to TDD uplink/downlink configuration 5, when corresponding different SIB1 are configured, the value of set K, specifically It is as follows：

Wherein, UE transmits the corresponding ACK/NACK information of downlink subframe n-k, k ∈ K in sub-frame of uplink n, and blackens part It is digital then be according to SIB1 configure determine HARQ feedback sequential relationship when, using sub-frame of uplink n transmit ACK/NACK information under Row subframe.

In addition, for traditional LTE TDD systems, LTE TDD systems support a variety of ACK/NACK feedback systems, for example, channel selection（Channel selection）、PUCCH format3（Physical Uplink Control Channel form 3）Deng.Wherein, Channel selection are advantageous in that PUCCH used in transmission（Physical uplink control channel）Resource overhead compared with It is small, but its bearer cap is limited, can only at most feed back 4 bit informations.In addition, Channel selection can be preferably sharp With PUCCH implicit resources.And so-called PUCCH implicit resources, resource number is according to the PDCCH/EPDCCH of schedule data transmission （Physical Downlink Control Channel/enhanced Physical Downlink Control Channel）The physical resource elements of occupancy determine.Base station is according to being The expense of total PDCCH/EPDCCH reserves the PUCCH implicit resources of respective numbers in system.System is guarantee backwards compatibility, this Class implicit resource there must be.And the benefit of PUCCH format 3 is then to be that bearer cap is big, corresponding PUCCH resource It is explicitly configured by base station.

In practical application, in LTE Rel-8 systems, when UE uses channel selection modes（Rel-8 ranks Become ACK/NACK in segment standard and be multiplexed multiplexing patterns）When transmitting ACK/NACK.For in same sub-frame of uplink M downlink subframe of transmitting feedback information, UE will be to multiple code words in each downlink subframe（If it is configured with more codeword transmissions Pattern）Corresponding ACK/NACK feedback informations merge（I.e. space merges, spatial bundling）, to not receiving data Downlink subframe generate NACK/DTX（Discontinuous transmission, Discontinues Transmission）As feedback information, obtain After the ACK/NACK feedback informations of M-bit, according to the correspondence of table 2~4, it is in numberPUCCH resource upload Defeated b（0）, b（1）.Table 2~4 is specific as follows：

In table 2.LTE Rel-8 systems, M is equal to 2 ACK/NACK mapping forms

Table 3 is in LTE Rel-8 systems, and M is equal to 3 ACK/NACK mapping forms

In table 4.LTE Rel-8 systems, M is equal to 4 ACK/NACK mapping forms

And in LTE Rel-10 systems, it still supports to transmit not more than 4 ratios using the mode of channel selection Special ACK/NACK information, and 3 new ACK/NACK mapping forms are respectively defined again, as shown in table 5~7.New form with Comparing before, without overlap condition, therefore performance is more excellent.Table 5~7 is specific as follows：

In table 5.LTE-A Rel-10 systems, M is equal to 2 ACK/NACK mapping forms

In table 6.LTE-A Rel-10 systems, M is equal to 3 ACK/NACK mapping forms

Table 7.LTE-AIn Rel-10 systems, M is equal to 4 ACK/NACK mapping forms

However, when UE configurations transmit ACK/NACK information using PUCCH format 3 in existing non-dynamic TDD system When, DL DAI（Downlink assignment index, downlink distribution instruction）TPC letters in PDCCH/EPDCCH more than 1 Breath domain is used to indicate the resource of the PUCCH format 3 of transmission ACK/NACK feedback informations.At this point, UE only has received DL DAI>1 PDCCH/EPDCCH just uses 3 transmitting feedback informations of PUCCH format.And if UE only receives DL DAI=1 PDCCH/EPDCCH can then use PUCCH format 1a/1b transmitting feedback informations in PUCCH implicit resources.

And in existing dynamic TDD system, since UE is according to descending reference configuration work, receive under DL DAI=1 Row subframe may not be that SIB1 configures corresponding downlink subframe, at this point, being that there is no corresponding PUCCH implicit resources in system , therefore, it is impossible to transmit PUCCH.If at this point, increase instruction PUCCH in proprietary information domain directly in PDCCH/EPDCCH 3 resources of format, then can increase descending control signaling expense, influence system effectiveness.If always using in PDCCH/EPDCCH 3 resources of TPC information fields instruction PUCCH format, it will cause UE can not timely know PUCCH transmission powers adjustment letter Breath.

It is also at present the effective solution of proposition for the above situation in existing correlation technique.
