The method comprises the steps: dividing acknowledgment/non-acknowledgement (ACK/NACK) messages of a plurality of downlink subframes which correspond to an uplink subframe in a component carrier (CC) into two groups according to a downlink allocated index (DAI) value, wherein the ACK/NACK messages in each group respectively generate a 2-bit message in a bundling way; and feeding back the two groups of finally-generated 4-bit messages in the manner of channel selection. After the invention is used, the feedback of the ACK/NACK messages on the uplink subframe is realized when the configuration ratio of the uplink subframe to the downlink subframes is 1:9 in a time division duplex (TDD) system, the bit number of the ACK/NACK transmission is reduced, the channel capacity of a physical uplink control channel (PUCCH) is effectively utilized, the effective transmission of the ACK/NACK messages is guaranteed, and the system performance of the system is improved.
Description
Technical field
The present invention relates to the communications field, relate in particular to a kind of sending method and device of up confirmation.
Background technology
Long Term Evolution (LTE, Long Term Evolution) system is with OFDM (OFDM, Orthogonal Frequency Division Multiplexing) and multiple-input and multiple-output (MIMO, Multi-input Multi-output), can on the spectral bandwidth of 20MHz, provide the peak rate of up 50Mbps and descending 100Mbps as core technology.Compare with 3G, LTE has higher message transmission rate, can improve performance, raising cell capacity, the reduction system delay of Cell Edge User, and can realize wide area covering and backward compatible, therefore is regarded as the mainstream technology of 3G to 4G evolution.
In the LTE system, affirmation/non-affirmation (ACK/NACK) feedback signal is inequality in Frequency Division Duplexing (FDD) (FDD, Frequency Division Duplexing) system and time division duplex (TDD, Time Division Duplexing) system.In the FDD system, owing to be to concern one to one between sub-frame of uplink and the descending sub frame, so the ACK/NACK of each descending sub frame feedback is carried on the corresponding sub-frame of uplink.And in the TDD system,, therefore consider the problem how the ACK/NACK feedback of these a plurality of descending sub frame correspondences sends on a sub-frame of uplink with regard to needs owing to there is the scene of the simultaneously corresponding sub-frame of uplink of a plurality of descending sub frames.
At present, the ACK/NACK feedback system under the TDD has two kinds, is respectively binding (bundling) pattern and multiplexing (Multiplexing) pattern.As the capable physically control channel (PUCCH of ACK/NACK, when Physical Uplink Control Channel) going up feedback, under the bundling pattern, a plurality of ACK/NACK of a plurality of descending sub frame correspondences become 1bit by logical AND operation bundling on each streams of code words, like this, ACK/NACK feedback on a plurality of descending sub frames has been reduced to maximum 2bit by logical AND, can feed back on the sub-frame of uplink of a correspondence.Under the Multiplexing pattern, carry out the ACK/NACK logical AND operation between the streams of code words on each descending sub frame, it is space binding (spatial bundling), M descending sub frame correspondence the ACK/NACK bit after M logical AND, the information of 2bit is finally fed back in the mode that this M bit is selected by PUCCH Format1b and the channel back of tabling look-up.Like this, in the TDD system, just can solve ascending-descending subframes and dispose ACK/NACK feedback problem when asymmetric by bundling mode or multiplexing mode.
In tdd mode, the uplink-downlink configuration that each subframe is supported is as shown in table 1 below:
Table 1
Wherein, " D " expression is exclusively used in the subframe of downlink transfer; " U " expression is exclusively used in the subframe of uplink; " S " expression is used for descending pilot frequency time slot (DwPTS; Downlink Pilot Time Slot), protection interval (GP; Guard Period) and the special subframe in these three territories of uplink pilot time slot (UpPTS, Uplink Pilot Time Slot).The frame structure of TDD system as shown in Figure 1, wherein, T
SMinimum time unit in the expression radio frames, T
fThe duration of a radio frames of expression, T
SlotThe duration of a time slot in the expression radio frames.
As can be seen from the above table, in ascending-descending subframes configuration 5, a sub-frame of uplink need feed back the ACK/NACK of 9 descending sub frames simultaneously, and promptly ascending-descending subframes was configured to 1: 9.If ACK/NACK feeds back, need to consider how to feed back the problem of a plurality of ACK/NACK bits, yet prior art also can't provide the solution that addresses the above problem by the bundling mode under channel selective mode.
Summary of the invention
In view of this, main purpose of the present invention is to provide a kind of sending method and device of up confirmation, to realize that ascending-descending subframes was configured to, the feedback of a plurality of ACK/NACK on a sub-frame of uplink in the TDD system at 1: 9 o'clock.
