Summary of the invention

The version 8 of third generation partner program (3GPP) Long Term Evolution (LTE) standard is described on the physical uplink link sharing channel (PUSCH) incidentally uplink control information (UCI).CQI/precoding matrix indicators (CQI/PMI) resource is placed in the beginning of uplink shared channel (UL-SCH) data resource, and before next subcarrier continues, be mapped in order all single-carrier frequency division multiple access (SC-FDMA) symbol on the subcarrier.UL-SCH data and CQI/PMI data are mated in speed.By puncturing (puncture) PUSCH data resource element (RE), with the HARQ-ACK resource mapping to the SC-FDMA symbol.Therefore, reduce the PUSCH RE that is punctured by the HARQ-ACK symbol and will improve the PUSCH performance.

According to above content, version 8 provide be down link control information (DCI) form 0/4,

2 downlink allocation index (DAI), it is used to indicate the total quantity that the down link (DL) in bundled window distributes.Suppose that bundled window size is M, if be that 0/4 the PDCCH that detects regulates the PUSCH transmission based on the DCI form, then only Individual HARQ-ACK position but not the M position need to feed back to transmitting device, for example higher-level node base station (eNB).Thereby, reduce corresponding to not by the DL subframe of eNB scheduling Individual useless HARQ-ACK position.

The version 10 of LTE standard (Rel-10) has been introduced carrier aggregation, and wherein, more than one-component carrier wave (CC) can be used for transfer of data.In version 10 time division duplexs (TDD) system, in the situation that PUSCH carries out incidentally, HARQ-ACK code book size is determined by the quantity of CC, their transmission mode of configuration and the quantity of the downlink subframe in the bundled window.For TDD UL-DL configuration 1-6, and when for the transmission configuration PUCCH form 3 of HARQ-ACK, HARQ-ACK code book size is definite by following equation:

(1)。

Wherein, C is the quantity of the CC of configuration,

The quantity that disposes the CC of multiple-input and multiple-output (MIMO) transmission mode that makes it possible to receive two transmission blocks;

That UE need to feed back to it quantity of downlink subframe of the HARQ-ACK position of c Serving cell.To suppose on the PUSCH subframe n for TDD UL-

DL configuration

For:

(2)。

Wherein, according to following table,

Determined by the DAI that adopts DCI form 0/4:

Table 1

[0008]DAI can have at the subframe n with each Serving cell in the predetermined subframe that is mutually related and transmits.For example, DAI can be in subframe

Middle transmission defines in following table

:

Table 2

[0009]Because it is always identical that the TDD UL-DL of each Serving cell is configured among the Rel-10, and Certainly be not more than the bundled window size, so

Determined HARQ-ACK code book size always equals minimum HARQ-ACK bit quantity, and is the optimal compromise between HARQ-ACK expense and the performance.

In the version 11 of 3GPP LTE standard, the interband CA of TDD with CC (each Serving cell is had different UL-DL configuration) is supported.In different Serving cells, have different UL-DL configurations and can produce different HARQ-ACK bundled windows.Therefore, the HARQ-ACK code book size based on UL allowance (grant) in the former version is determined effectively to reduce the HARQ-ACK expense.
