Table one

Table two

Feedback scheme according to prior art FDD HARQ; If the UL subframe of the FDDUL frequency range of DL subframe correspondence is a blank frame in the FDD DL frequency range; Like FDD DL

frequency range subframe

1,2,6 and 7, its UL feedback subframe is the

wireless sub-frame

0 and 1 of

UL subframe

5,6 and next radio frames in the FDD UL frequency range.Because (the DL subframe of TDD configuration 0 is 0 to the DL subframe of the TDD access link of the wireless sub-frame 0 of

UL subframe

5,6 and next radio frames and 1 pair of neighbor cell in the FDD UL frequency range; 1; 5,6) interfere with each other, and be set to blank frame; Can't carry out the feedback of UL data, promptly in FDD UL frequency range, can't carry out the UL feedback of DL transfer of data on the

wireless sub-frame

0 and 1 of

UL subframe

5,6 and next radio frames.

Because the above-mentioned interference relation of evading, the DL subframe 5 of

configuration

0 and 6 and the

wireless sub-frame

0 and 1 of next radio frames in the TDD system in the FDD UL frequency range in the wireless sub-frame 0 of

UL subframe

5,6 and next radio frames and 1 correspondence table one.Table three, the configuration of TDD configuration in table four and the table five and the blank frame of FDD UL is similarly, the configuration of DL sub-frame configuration and blank frame is similar in table six.In order to make description clearer, be configured to example with TDD among the present invention and describe.

Press FDD HARQ sequential relationship; The sub-frame of uplink (n+4) that descending sub frame in the DL frequency range (n) is corresponding is as the UL feedback subframe of descending sub frame n; For example adopt FDD HARQ sequential relationship; FDD DL frequency range descending sub frame 1,2,6 and 7 UL feedback subframe are the wireless sub-frame 0 and 1 of UL subframe 5,6 and next radio frames, shown in the dotted line among Figure 11.But the wireless sub-frame 0 and 1 of UL subframe 5,6 and next radio frames all is a blank frame; Can not carry out the data feedback; With the blank frame frame number is the beginning, adopts the feedback relationship of the TDD HARQ sequential of table two, and the UL subframe (blank frame) of the FDD UL frequency range that DL subframe n is corresponding in the FDD DL frequency range that promptly blank frame is corresponding is n+4; The up feedback subframe of confirming to the end from blank frame is (n+4)+k, and wherein k is the k in the table two TDD HARQ time-scale.DL subframe n is n+ (4+k) to the up feedback subframe of FDD UL frequency range from the corresponding FDD DL frequency range of blank frame; Formed a kind of new sequential relationship K '=k+4, DL subframe n is k '=4 to the up feedback subframe of FDD UL frequency range in the FDD DL frequency range of other non-blank-white frame correspondence.Shown in table three, wherein "-" part is represented the sequential of FDD, K '=4 just, and other sequential relationships are K '=k+4.Grey color part in the table three is optional part, can not be embodied in the table three.

Table three, the HARQ sequential relationship of setting

The reason of evading owing to interference; In the FDD UL subframe with TDD configuration in the UL subframe of the corresponding FDD UL frequency range of DL subframe be blank frame; With TDD configuration in the table one 0 is example, the situation of other configurations (such as TDD configuration 1 to TDD configuration 6) and the class of operation of configuration 0 seemingly, as follows:

1102,,, confirm the position of the UL feedback subframe of the pairing DL data of said blank frame according to the HARQ sequential relationship of said setting if the corresponding UL subframe of DL subframe is a blank frame in the FDD DL frequency range.

The position of blank subframe is set by the base station, and UE can be known through base station broadcast or dedicated signaling advice method then.

For example the

UL subframe

0,1,5,6 in the FDD UL frequency range that is configured to of UE blank frame is notified in the base station.

DL subframe 1; 2; In 6, the 7 corresponding FDD UL frequency ranges UL subframe 0 of

UL subframe

5,6 and next radio frames and 1 and the TDD system in configuration 0

DL subframe

5 and 6 and the

subframe

0 and 1 of next radio frames, wherein;

Subframe

5,6 and

next radio frames

0 and 1 are blank frame, like the configuration of above-mentioned base station notice.This configuration and TDD configuration 0 coupling are according to the HARQ sequential relationship of setting, promptly in table three; Search according to DL subframe numbers in TDD configuration 0 and the FDD DL frequency range, confirm

DL subframe

1,2 in the FDD DL frequency range; 6,7 UL feedback subframe is respectively: the UL feedback subframe of subframe 1 is a 1+8=9 work song frame; The UL feedback subframe of subframe 2 is a 2+10=12 work song frame, is the wireless sub-frame 2 of next radio frames; The UL feedback subframe of subframe 6 is a 6+8=14 work song frame, is the wireless sub-frame 4 of next radio frames; The UL feedback subframe of subframe 7 is a 7+10=17 work song frame, is the wireless sub-frame 7 of next radio frames.

If the UL subframe of the FDD UL frequency range of DL subframe correspondence is the non-blank-white frame in the FDD DL frequency range, then use FDD HARQ feedback sequential to feed back.Such as,

DL subframe

0 and 3,4 in the FDD DL frequency range, 5,8,9 its according to the UL subframe in the corresponding FDD UL frequency range of FDD HARQ feedback sequential be: 4,7,8,9, and the

wireless sub-frame

2,3 of next radio frames.Because the UL subframe in the FDD

UL frequency range

2,3,4,7,8,9 is a sub-frame of uplink, and is the non-blank-white frame, so can do the up feedback of DL subframe in the corresponding FDD DL frequency range.

If press FDD HARQ sequential relationship; The UL subframe of the FDD UL frequency range of DL subframe correspondence is a blank frame in the FDD DL frequency range; Like FDD DL

frequency range subframe

1,2,6 and 7; According to FDD HARQ sequential relationship, its UL feedback subframe is the

wireless sub-frame

0 and 1 of

UL subframe

5,6 and next radio frames in the FDD UL frequency range.Owing to disturb the relation of evading; So in the FDD UL frequency range wireless sub-frame 0 of

UL subframe

5,6 and next radio frames and 1 and the TDD system in configuration 0

DL subframe

5 and 6 and the

wireless sub-frame

0 and 1 of next radio frames corresponding one by one; And be set to blank frame, can't carry out the feedback of UL data.

Under FDD DL subframe numbers, the FDD UL subframe numbers situation identical, be referred to as direct correspondence in the present invention with the TDD subframe numbers.

When the directly corresponding UL feedback subframe of DL subframe (n) up-downgoing data in the FDD DL frequency range is blank frame; HARQ sequential by setting is fed back; The sub-frame of uplink directly corresponding from the DL subframe begins; Adopt TDD HARQ sequential, the up feedback subframe of definite downlink data is n+k, and promptly the HARQ sequential corresponding relation of this moment is K '=k.

Shown in figure 12; By the

UL subframe

5,6 of the FDD HARQ feedback of the visible FDD DL

frequency range subframe

1,2,6 of top description and 7 and the

wireless sub-frame

0 and 1 of next radio frames is blank frame; The directly corresponding UL subframe of FDD DL

frequency range subframe

1 and 6 also is a blank frame simultaneously, and the position of blank frame is consistent with the DL time slot position that TDD disposes in 0 all.At this moment the feedback of FDD DL

frequency range subframe

1 and 6 UL subframe directly adopts

DL subframe

1 and 6 feedback parameter the K '=k in the TDD HARQ sequential in the TDD configuration 0; Be respectively 6 and 6; So the position of its UL feedback subframe is 1+6=7 work song frame and 6+6=12, the wireless sub-frame 2 of next radio frames.

And

DL subframe

2 and 7; Press the sequential feedback relationship of FDD; The directly corresponding

UL subframe

2 and 7 of FDD DL

frequency range subframe

2 and 7 is not a blank frame, adopts the HARQ sequential of setting, and the blank frame corresponding with FDD DL frequency range DL subframe is initial; Press TDD HARQ sequential, the UL subframe of blank frame corresponding downlink data feedback is fed back subframe as UL.The UL subframe of carrying out the downlink data feedback that FDD DL frequency range DL subframe is corresponding is for being initial with the blank frame frame number promptly; Adopt the feedback relationship of TDD HARQ sequential; I.e. (n+4)+k; Then DL subframe n is n+ (4+k) to the up feedback subframe of FDD UL frequency range from the corresponding FDD DL frequency range of blank frame, has formed a kind of new sequential relationship K '=k+4.

The blank frame corresponding with FDD DL frequency range DL subframe is initial, presses TDD HARQ sequential, and the UL subframe of carrying out the downlink data feedback that blank frame is corresponding is fed back subframe as UL; Be K '=k+4; Formed a kind of new sequential relationship shown in table four, wherein " oblique line " part is TDD sequential K '=k value, and "-" part is represented the sequential of FDD; K '=4 just, other sequential are K '=k+4.Grey color part in the table four is optional part, can not be embodied in the table four.
