Description

The scheduling of a kind of PUSCH and the transmission method of HARQ-ACK information

Technical field

The present invention relates to wireless communication system technologies, particularly PUSCH scheduling and the transmission method of HARQ-ACK information in a kind of FDD and TDD CA system.

Background technology

Long Term Evolution (LTE) system supports Frequency Division Duplexing (FDD) (FDD) and time division duplex (TDD) two kinds of duplex modes.Fig. 1 is the frame structure of TDD system.The length of each radio frames is 10ms, and it is divided into two length is the field of 5ms.Each field comprises the time slot and 3 special domain that 8 length are 0.5ms, i.e. descending pilot frequency time slot (DwPTS), protection interval (GP) and uplink pilot time slot (UpPTS), and the length sum of these 3 special domain is 1ms.Each subframe is made up of two continuous print time slots, and namely a kth subframe comprises time slot 2k and time slot 2k+1.TDD system supports 7 kinds of different TDD upstream and downstream configurations, as shown in table 1.In table 1, D represents descending sub frame, and U represents sub-frame of uplink, and S represents the above-mentioned special subframe comprising 3 special domain.

The upstream and downstream configuration of table 1:LTE TDD

The TDD system of LTE supports HARQ mechanism, and its general principle comprises: base station is that UE distributes ascending resource; UE utilizes ascending resource to send upstream data to base station; Base station receives upstream data and sends HARQ indication information to UE, and UE carries out the re-transmission of upstream data according to this indication information.Concrete, UE carries upstream data by PUSCH, base station is by Physical Downlink Control Channel (PDCCH, Physical Downlink Control Channel) or strengthen Physical Downlink Control Channel (EPDCCH, Enhanced Physical Downlink Control Channel) carry the scheduling and controlling information of PUSCH, i.e. uplink authorization (UL Grant), base station carries HARQ indication information by physical mixing retransmission indicating chanel (PHICH).In above process, the determination of the timing position that PUSCH once transmits and follow-up re-transmission timing position is based on pre-configured timing relationship, comprise the timing relationship of the timing relationship of UL Grant to PUSCH, the timing relationship of PHICH to PUSCH and PUSCH to PHICH, hereinafter above-mentioned three timing relationships are collectively referred to as PUSCH synchronous HARQ timing relationship.

First, the timing relationship of the UL Grant or PHICH to PUSCH in LTE and LTE-A is introduced.

For FDD configuration, UE is subframe sequence number at descending sub frame n(n, lower same) receive UL Grant or PHICH, then this UL Grant is used for the PUSCH in dispatching uplink subframe n+k.Here the value of k equals 4.

To the timing relationship of UL Grant to PUSCH, suppose that UE is subframe sequence number at descending sub frame n(n, lower same) receiving UL Grant, then this UL Grant is used for the PUSCH in dispatching uplink subframe n+k.Here the value of k defines in table 2.Specifically, concerning TDD upstream and downstream configuration (or being called for short upstream and downstream configuration) 1 ~ 6, the quantity of sub-frame of uplink is less than or equal to descending sub frame (S frame can be used as descending sub frame), for any descending sub frame n, by a unique k value, unique PUSCH synchronous HARQ timing relationship can be configured, reflect in table 2, can not PUSCH be dispatched in a descending sub frame, or the PUSCH in a sub-frame of uplink can only be dispatched; And concerning TDD upstream and downstream configuration 0, the quantity of sub-frame of uplink is greater than descending sub frame, the PDCCH/EPDCCH of each descending sub frame needs the PUSCH in scheduling two sub-frame of uplink, for this reason, k value can not be unique, need the PUSCH supported in PDCCH/EPDCCH line index (UL index) technology in scheduling two sub-frame of uplink, for the PUSCH that index is different, use different k values.Such as, when UE receives PDCCH/EPDCCH at descending sub frame 0, its scheduling be PUSCH in sub-frame of uplink 4 and/or sub-frame of uplink 7; When UE receives PDCCH/EPDCCH at descending sub frame 1, its scheduling be PUSCH in sub-frame of uplink 7 and/or sub-frame of uplink 8.

To the timing relationship of PHICH to PUSCH, in LTE and LTE-A, the PHICH resource collection for the PUSCH independent allocation in each sub-frame of uplink, suppose that UE receives PHICH at descending sub frame n, then this PHICH is for controlling the PUSCH in sub-frame of uplink n+j.Here the value of j defines in table 2.Specifically, concerning TDD upstream and downstream configuration 1 ~ 6, the quantity of sub-frame of uplink is less than or equal to descending sub frame, for any descending sub frame n, by a unique j value, unique PUSCH synchronous HARQ timing relationship can be configured, reflect in table 2, PHICH resource collection can not be configured in a descending sub frame, or the PHICH resource collection of a sub-frame of uplink can only be configured; Concerning TDD upstream and downstream configuration 0, the quantity of sub-frame of uplink is greater than descending sub frame, then j value is not unique, but be configured with two PHICH resource collection respectively at descending sub frame 0 and 5, i.e. PHICH resource 0 and PHICH resource 1, for different PHICH resource, uses different j values.Such as, when UE receives PHICH at descending sub frame 0, the PUSCH in sub-frame of uplink 4 and/or sub-frame of uplink 7 can be triggered.

The timing relationship table of table 2 UL-Grant/PHICH to PUSCH

Secondly, the timing relationship of PUSCH to the PHICH in LTE and LTE-A is introduced.

To FDD configuration, when UE receives PHICH in descending sub frame n, the HARQ-ACK information of what this PHICH indicated is PUSCH in sub-frame of uplink n-h, the value of h equals 4.

Concerning TDD upstream and downstream configuration 1 ~ 6, when UE receives PHICH in descending sub frame n, the HARQ-ACK information of what this PHICH indicated is PUSCH in sub-frame of uplink n-h, the value of h is as shown in table 3.

Concerning TDD upstream and downstream configuration 0, owing to being configured with two PHICH resource, then when the PHICH resource 0 of UE in descending sub frame n receives PHICH, this PHICH indicates the HARQ-ACK information of the PUSCH in sub-frame of uplink n-h; And when UE receives PHICH in the PHICH resource 1 of descending sub frame 0 or descending sub frame 5, then this PHICH is the HARQ-ACK information of the PUSCH in instruction sub-frame of uplink n-6.

The timing relationship table of table 3 PUSCH to PHICH

According to the form (table 2 and table 3) of above-mentioned three kinds of timing relationships, PUSCH synchronous HARQ timing relationship when community (Cell) adopts a certain specific T DD upstream and downstream to configure can be determined, thus realize the synchronous transmission of PUSCH according to this PUSCH synchronous HARQ timing relationship.

Be sent to UE PDSCH or from UE transmission PUSCH can be dynamic dispatching or semi-continuous scheduling (SPS).PDSCH or the PUSCH transmission parameter of dynamic dispatching or semi-continuous scheduling are provided by the DCI transmitted in PDCCH/EPDCCH.The DCI format of scheduling PDSCH transmission is called as DL DCI format, and the DCI format of dispatching PUSCH transmission is called as UL DCI format.In order to reduce the number of times of DCI blind detection, the DCI format 1A of scheduling PDSCH transmission and the information bit of DCI format 0 when blind check dispatching PUSCH transmission are the same.

For TDD system, DL DCI comprises descending allocation index (DAI) territory of 2 bits, DL DAI is the counter that eNB sends to UE, is used to refer to the number sum that eNB has dispatched the PDCCH/EPDCCH that the number of the PDCCH/EPDCCH of PDSCH and descending semi-continuous scheduling (SPS) discharge in bundled window.In first DL DCI that eNB sends in bundled window, the value of DAI is the value of DAI in second DL DCI sending in bundled window of 1, eNB is 2, by that analogy.Use the value of DL DAI field, UE can judge whether it has missed the DL DCI format in same bundled window above, and can determine the HARQ-ACK feedback information of the same window according to whether having DL DCI to lose.In addition, for TDD upstream and downstream configuration 1,2,3,4,5 or 6, the UL DCI format 0/4 of scheduling PUSCH comprises the UL DAI field of 2 bits, instruction be the number of sub frames sum of the PDCCH/EPDCCH transmitting the number of sub frames of PDSCH and the release of descending semi-continuous scheduling in current bundled window, be used for determining when determining transmitting HARQ-ACK feedback information in PUSCH the bit number of HARQ-ACK.For TDD upstream and downstream configuration 0, the UL DCI format 0/4 of scheduling PUSCH comprises the UL index field of 2 bits, be used to refer to a descending sub frame when dispatching the PUSCH of 2 sub-frame of uplink, the PUSCH of PUSCH or 2 subframe of scheduling 1 subframe, and when the PUSCH of scheduling 1 subframe, scheduling be the PUSCH of which subframe.

In order to improve the transmission rate of user, propose enhancing (LTE-A) system of LTE system.In LTE-A, obtain larger bandwidth of operation by being polymerized multiple member carrier (CC, Component Carrier), i.e. carrier aggregation (CA, Carrier Aggregation), form the descending and up link of communication system, thus support higher transmission rate.To a UE, base station can be configured in multiple CC and work, and one of them is main CC(PCC or Pcell), and other CC are called auxiliary CC(SCC or Scell).

For CA system, UE may receive at a Cell PDSCH or PUSCH that PDCCH/EPDCCH dispatches another Cell, this function is called as across carrier dispatching (Cross-carrier Scheduling), be configured to a Cell also referred to as UE monitor and carry out the PDCCH/EPDCCH with carrier indication field (CIF) on another Cell comprising one across the DCI format of carrier dispatching and there is the corresponding carrier indication field of respective Cell (CIF).Such as, CIF-value is made up of 3 bits, and for UE is configured with 5 Cell, respective binary system CIF-value can be ' 000 ', ' 001 ', ' 010 ', ' 011 ', ' 100 ' 5 each Cell represented.UE may receive at same Cell PDSCH or PUSCH that PDCCH/EPDCCH dispatches same Cell, and this function is called as oneself scheduling (Self-scheduling).

Specify in lte-a system: the multiple Cell condensed together or all employing FDD configuration, or all adopt TDD configuration.

In order to further improve the transmission rate of user, in the follow-up study of LTE-A, an important problem is exactly how research effectively supports that the Cell of Cell and the FDD configuration of TDD configuration carries out the situation of carrier aggregation.Such as: when comprising the Cell of Cell and FDD configuration of TDD configuration in carrier aggregation, how UE determines to dispatch the form of PDCCH/EPDCCH of Physical Downlink Shared Channel (PDSCH) and Physical Uplink Shared Channel (PUSCH) is a technical problem urgently to be resolved hurrily.

Situation 1:

When the Serving cell that UE configures is Pcell or Scell, and the Serving cell configured is FDD configuration, and the PUSCH synchronous HARQ timing relationship of FDD is deferred in described Serving cell, when the PDSCH of described Serving cell defers to the HARQ-ACK timing relationship of FDD, UL DCI adopts existing FDD to define, and does not wherein comprise UL DAI territory or UL index territory, and DL DCI adopts existing FDD to define, wherein do not comprise DL DAI territory, HARQ procedure number (HARQ process number) territory is 3 bits.That is, make the bit number of UL DCI0 and DL DCI1A equal according to the method for process FDD system.

Situation 2:

When the Serving cell that UE configures is Pcell or Scell, and the Serving cell configured is TDD configuration, and the PUSCH synchronous HARQ timing relationship of TDD is deferred in described Serving cell, when the PDSCH of described Serving cell defers to the HARQ-ACK timing relationship of TDD, UL DCI adopts existing TDD definition, and comprising UL DAI or UL index territory, DL DCI adopts existing TDD definition, comprising the DL DAI territory of 2 bits, and HARQ procedure number field is 4 bits.That is, make the bit number of UL DCI0 and DL DCI1A equal according to the method for process TDD system.

Situation 3:

When the Serving cell that UE configures is Scell, and the Serving cell configured be TDD configuration or FDD configuration (such as Pcell be FDD configuration time, Scell when Scell is TDD configuration is described Serving cell) and the PUSCH synchronous HARQ timing relationship that TDD configures is deferred in described Serving cell, when the PDSCH of described Serving cell defers to the HARQ-ACK timing relationship of FDD configuration, the definition of UL DCI and DL DCI, the method for designing of the DL DAI in the UL DAI in UL DCI or the design of UL index and DL DCI is described below.

When the PUSCH synchronous HARQ timing relationship of TDD upstream and downstream configuration 0 is deferred in described Serving cell, TDD is adopted to define according to the DCI format 0/4 of the PDCCH/EPDCCH of the synchronous HARQ timing relationship scheduling PUSCH of TDD, comprising UL index territory, be used to refer to a descending sub frame when dispatching the PUSCH of 2 sub-frame of uplink, scheduling 1 subframe or the PUSCH of 2 subframes, and when the PUSCH of scheduling 1 subframe, scheduling be the PUSCH of which subframe.

When the PUSCH synchronous HARQ timing relationship of TDD upstream and downstream configuration 1,2,3,4,5 or 6 is deferred in described Serving cell, the definition adopted according to the DCI format 0/4 of the PDCCH/EPDCCH of the synchronous HARQ timing relationship scheduling PUSCH of TDD has 3 kinds of modes:

1st kind of mode: due to defer to when described Serving cell TDD upstream and downstream configuration 0 PUSCH synchronous HARQ timing relationship time, TDD definition is have employed according to the DCI format 0/4 of the PDCCH/EPDCCH of the synchronous HARQ timing relationship scheduling PUSCH of TDD, in order to keep the form of UL DCI when deferring to different PUSCH synchronous HARQ timing relationship consistent, when TDD upstream and downstream configuration 1 is deferred in described Serving cell, 2, 3, 4, 5 or 6 PUSCH synchronous HARQ timing relationship time, TDD is adopted to define according to the DCI format 0/4 of the PDCCH/EPDCCH of the synchronous HARQ timing relationship scheduling PUSCH of TDD, comprising the UL DAI territory of 2 bits, what indicate is the number of sub frames sum transmitting the number of sub frames of PDSCH and the PDCCH/EPDCCH of descending semi-continuous scheduling release in current bundled window, the bit number of HARQ-ACK when being used for determining transmitting HARQ-ACK feedback information in PUSCH,

2nd kind of mode: due to defer to when described Serving cell TDD upstream and downstream configuration 0 PUSCH synchronous HARQ timing relationship time, TDD definition is have employed according to the DCI format 0/4 of the PDCCH/EPDCCH of the synchronous HARQ timing relationship scheduling PUSCH of TDD, in order to keep the form of UL DCI when deferring to different PUSCH synchronous HARQ timing relationship consistent, when TDD upstream and downstream configuration 1 is deferred in described Serving cell, 2, 3, 4, 5 or 6 PUSCH synchronous HARQ timing relationship time, TDD is adopted to define according to the DCI format 0/4 of the PDCCH/EPDCCH of the synchronous HARQ timing relationship scheduling PUSCH of TDD, comprising 2 bit UL DAI territories, and UL DAI is as reservation bit.

3rd kind of form: in order to reduce the expense of DCI, adopts FDD to define according to the DCI format 0/4 of the PDCCH/EPDCCH of the synchronous HARQ timing relationship scheduling PUSCH of TDD, does not wherein comprise UL DAI territory.The form of UL DCI when at this moment deferring to the PUSCH synchronous HARQ timing relationship of TDD upstream and downstream configuration 1,2,3,4,5 or 6 is different from the bit number of the form of the UL DCI deferred to when TDD upstream and downstream configures the PUSCH synchronous HARQ timing relationship of 0.

Design for DL DAI is described below:

When the PUSCH synchronous HARQ timing relationship of TDD upstream and downstream configuration 0 is deferred in the Serving cell that UE configures, the DCI format 0 of the PDCCH/EPDCCH of scheduling PUSCH adopts TDD to define, comprising UL index territory, the DCI format 1A of the described scheduling of the HARQ-ACK timing relationship according to FDD PDSCH can adopt TDD to define, comprising 2 bit DL DAI territories, be used to refer to the number sum that eNB has dispatched the number of the PDCCH/EPDCCH of PDSCH and the PDCCH/EPDCCH of descending SPS release in bundled window, or as reservation bit, HARQ procedure number field is 4 bits, thus keep identical with the bit number of TDD DCI format 0, or the DCI format 1A of the described scheduling of the HARQ-ACK timing relationship according to FDD PDSCH adopts FDD definition, and the DCI format 1A of extra directly packing ratio special envoy FDD is identical with the bit number of TDD DCI format 0.To a TDD system, the original bit number of DCI format 0 and DCI format 1A may be unequal, and in order to make their bit number equal, the DCI format less to bit number wherein adds filling bit.Like this, for the scheme that the DCI format 1A of above-mentioned extra packing ratio special envoy FDD is identical with the bit number of TDD DCI format 0, two kinds of methods can be had to have 2 kinds of defining method to the bit number of the DCI format 0 determining described TDD, method 1: to described Serving cell, the bit number of the original bit number of the DCI format 0 of TDD and the DCI format 1A of TDD is compared, and ensure that the DCI format 0 of TDD is equal with the bit number of the DCI format 1A of TDD by bit padding, using the bit number of the TDD DCI format 0 that the bit number after relatively also filling compares as the DCI format 1A with FDD, method 2: to described Serving cell, will compare with the DCI format 1A of its TDD and the bit number of DCI format 0 of original TDD before filling bit, as the bit number that the DCI format 1A with FDD compares.

By above-mentioned definition, consistent with DCI format 0 bit number of tdd mode according to the DCI 1A of FDD timing relationship scheduling PDSCH, based on this, the DCI format 1/1B/1D/2/2A/2B/2C/2D of the described scheduling of the HARQ-ACK timing relationship according to FDD PDSCH can adopt the following two kinds: a, TDD definition is adopted according to the DCI format 1/1B/1D/2/2A/2B/2C/2D of the HARQ-ACK timing relationship scheduling PDSCH of FDD, comprising 2 bit DL DAI territories, be used to refer to the number sum that eNB has dispatched the PDCCH/EPDCCH that the number of the PDCCH/EPDCCH of PDSCH and descending semi-continuous scheduling (SPS) discharge in bundled window, or as reservation bit, HARQ procedure number field is 4 bits, thus be consistent with DCI format 1A, b, because there is not the demand controlling blind Detecting number of times, do not need consistent with other DCI format bit number according to the DCI format 1/1B/1D/2/2A/2B/2C/2D of the HARQ-ACK timing relationship scheduling PDSCH of FDD, so FDD also can be adopted to define, wherein do not comprise 2 bit DL DAI territories, HARQ procedure number field is 3 bits, adopt in this way, the expense of DCI can be reduced.Meanwhile, for carrying out the mutual difference of the DCI of different-format, the DCI format 1/1B/1D/2/2A/2B/2C/2D of usual identical definition should be different from the bit number of DCI format 1A; If because DCI format 1/1B/1D/2/2A/2B/2C/2D adopts FDD definition, and DCI format 1A is identical with DCI format 0 bit number of tdd mode with DCI format 0, cause DCI format 1/1B/1D/2/2A/2B/2C/2D equal with the bit number of DCI format 1A, so 1 bit can be filled in the end of DCI format equal for bit number in DCI format 1/1B/1D/2/2A/2B/2C/2D, thus ensure that the DCI format 1/1B/1D/2/2A/2B/2C/2D after filling should be different from the bit number of DCI format 1A.

When the PUSCH synchronous HARQ timing relationship of TDD upstream and downstream configuration 1,2,3,4,5 or 6 is deferred in the Serving cell that UE configures, the definition that can adopt according to the DCI format 1/1A/1B/1D/2/2A/2B/2C/2D of the PDCCH/EPDCCH of the HARQ-ACK timing relationship scheduling PDSCH of FDD has 2 kinds of modes:

Mode 1: during owing to deferring to the PUSCH synchronous HARQ timing relationship of TDD upstream and downstream configuration 0 in the Serving cell configured as UE, the definition of TDD is adopted according to the DCI format 0 of the PDCCH/EPDCCH of the synchronous HARQ timing relationship scheduling PUSCH of TDD, in order to keep the form of UL DCI consistent, when TDD upstream and downstream configuration 1 is deferred in the Serving cell that UE configures, 2, 3, 4, 5 or 6 PUSCH synchronous HARQ timing relationship time, TDD is adopted to define according to the DCI format 0 of the PDCCH/EPDCCH of the synchronous HARQ timing relationship scheduling PUSCH of TDD, therefore the DCI format 1A of the PDCCH/EPDCCH of described UE scheduling PDSCH will keep identical with the bit number of DCI format 0, the described DCI format 1A according to FDD timing relationship scheduling PDSCH adopts TDD definition, comprising 2 bit DL DAI territories, be used to refer to the number sum that eNB has dispatched the PDCCH/EPDCCH that the number of the PDCCH/EPDCCH of PDSCH and descending semi-continuous scheduling (SPS) discharge in bundled window, or as reservation bit, HARQ procedure number field is 4 bits, thus keep identical with the bit number of TDD DCI format 0.Because DCI format 1A have employed TDD definition, so, in order to keep the form of DL DCI consistent, described UE adopts TDD definition according to the DCI format 1/1B/1D/2/2A/2B/2C/2D of the PDCCH/EPDCCH of FDD timing relationship scheduling PDSCH, comprising 2 bit DL DAI territories, be used to refer to the number sum that eNB has dispatched the PDCCH/EPDCCH that the number of the PDCCH/EPDCCH of PDSCH and descending semi-continuous scheduling (SPS) discharge in bundled window, or as reservation bit, HARQ procedure number field is 4 bits, thus is consistent with DCI format 1A.Because there is not the demand controlling blind Detecting number of times, do not need consistent with other DCI format bit number according to the DCI format 1/1B/1D/2/2A/2B/2C/2D of the HARQ-ACK timing relationship scheduling PDSCH of FDD, so FDD also can be adopted to define, wherein do not comprise 2 bit DL DAI territories, HARQ procedure number field is 3 bits, adopt in this way, the expense of DCI can be reduced.

Mode 2: in order to reduce expense, when the PUSCH synchronous HARQ timing relationship of TDD upstream and downstream configuration 1,2,3,4,5 or 6 is deferred in the Serving cell that UE configures, adopt the definition of FDD according to the DCI format 0 of the PDCCH/EPDCCH of TDD synchronous HARQ timing relationship scheduling PUSCH, described UE adopts FDD definition according to the DCI format 1/1A/1B/1D/2/2A/2B/2C/2D of the PDCCH/EPDCCH of the HARQ-ACK timing relationship scheduling PDSCH of FDD;

Situation 4:

When the Serving cell that UE configures is Scell, and the Serving cell of configuration is TDD configuration or FDD configuration, (when such as Pcell is TDD configuration, Scell when Scell is FDD configuration is described Serving cell) and the PUSCH synchronous HARQ timing relationship of FDD is deferred in described Serving cell, when the PDSCH of described Serving cell defers to the HARQ-ACK timing relationship of TDD, TDD definition is adopted according to the DL DCI of the HARQ-ACK timing relationship scheduling PDSCH of TDD configuration, comprising the DL DAI territory of 2 bits, HARQ procedure number field is 4 bits.The definition that UL DCI adopts, and the method for designing of UL DAI has 2 kinds of modes, describes respectively below.

Mode 1:

When the HARQ-ACK timing relationship of the PDSCH of TDD is deferred in the Serving cell that UE configures, the DL DCI of scheduling PDSCH adopts TDD definition, comprising the DL DAI territory of 2 bits, HARQ procedure number field is 4 bits, TDD is adopted to define, comprising the UL DAI territory of 2 bits according to the DCI format 0/4 of FDD synchronous HARQ timing relationship scheduling PUSCH.What UL DAI territory indicated is the number of sub frames sum transmitting the number of sub frames of PDSCH and the PDCCH of descending semi-continuous scheduling release in current bundled window, the bit number of HARQ-ACK when being used for determining transmitting HARQ-ACK feedback information in PUSCH.Like this, keep identical with the bit number of TDD DCI format 1A according to the DCI format 0 of FDD synchronous HARQ timing relationship scheduling PUSCH.

Mode 2: when the HARQ-ACK timing relationship of the PDSCH of TDD is deferred in the Serving cell that UE configures, the DL DCI of scheduling PDSCH adopts TDD definition, comprising the DL DAI territory of 2 bits, HARQ procedure number field is 4 bits, adopts FDD to define according to the DCI format 0/4 of FDD synchronous HARQ timing relationship scheduling PUSCH.To DCI format 0, the DCI format 0 of extra directly packing ratio special envoy FDD is identical with the bit number of TDD DCI format 1A.To DCI format 4, can additionally directly the DCI format 4 of packing ratio special envoy FDD be identical with the bit number of TDD DCI format 0, also directly can use the DCI format 4 of FDD, thus reduction expense.

To a TDD system, the original bit number of DCI format 0 and DCI format 1A may be unequal, and in order to make their bit number equal, the DCI format less to bit number wherein adds filling bit.Like this, the scheme that the DCI format 0 for above-mentioned extra packing ratio special envoy FDD is identical with the bit number of TDD DCI format 1A, can have two kinds of methods to determine the bit number of the DCI format 1A of described TDD.Method 1: to described Serving cell, the bit number of the DCI format 1A of described TDD refers to the original bit number of the DCI format 1A of TDD system; Method 2: to described Serving cell, the bit number of the DCI format 1A of its TDD refers to increases bit number after filling bit to the original bit of the DCI format 1A of TDD system.

The above-mentioned method flow dispatching PUSCH in the carrier aggregation system of TDD and FDD for providing in the application.Next, the HARQ-ACK information transmission method of PDSCH is provided.

Figure 12 is the method flow of transmitting HARQ-ACK information in the application.As shown in figure 12, the method comprises:

Step 1201:UE determines the CC of the HARQ-ACK timing relationship of PDSCH and the HARQ-ACK feedback information of transmission PDSCH according to the member carrier composition structure that UE configures;

Step 1202:UE is according to the HARQ-ACK timing relationship of the PDSCH determined, Physical Uplink Control Channel (Physical uplink control channel on the CC determined, or the upper HARQ-ACK feedback information sending PDSCH of Physical Uplink Shared Channel (Physical uplink shared channel, PUSCH) PUCCH).

The member carrier composition structure configured according to UE below by UE in embodiment 3 pairs of steps 1201 determines that the preferred approach of the HARQ-ACK timing relationship of PDSCH and the CC of transmitting HARQ-ACK information is described in detail.

Embodiment 3:

In the application, the HARQ-ACK information of the PDSCH of UE is all transmitted on Pcell.Wherein, when the Serving cell of UE is Pcell, on it, the HARQ-ACK timing relationship of PDSCH only configures relevant to Pcell, according to existing mode determination timing relationship, just repeats no more below; When the Serving cell of UE is Scell, on it, the HARQ-ACK timing relationship of PDSCH is relevant to the configuration of Pcell and Scell, and lower mask body provides Serving cell when being Scell, determines the concrete mode of HARQ-ACK timing relationship.

Situation 1:

Pcell is the TDD configuration of dynamic change, and Serving cell Scell is FDD configuration.

It is the community of the TDD upstream and downstream configuration of dynamic change due to described Pcell, if the descending reference upstream and downstream configuration of the Scell of FDD configuration is along with the dynamic TDD upstream and downstream configuration variation of described Pcell, the HARQ-ACK information bit of the PDSCH that each sub-frame of uplink of Pcell can be made to transmit is more even.If but dynamically change the descending reference upstream and downstream configuration of TDD allocating cell, so the edge of descending reference upstream and downstream configuration change can cause the confusion of HARQ-ACK bundled window, based on this, in the application as the configuration of described Pcell, the configuration of the descending reference upstream and downstream of described Pcell is determined that the descending reference upstream and downstream of the Scell that FDD configures configures.Wherein, the descending reference upstream and downstream configuration of described Serving cell defines following several method:

The first forms structure according to the cell of UE configuration and determines that the method for the Cell of HARQ-ACK timing relationship and transmitting HARQ-ACK information is: the HARQ-ACK timing relationship that all Cell being configured to FDD all adopt the descending reference upstream and downstream of Pcell to configure; The HARQ-ACK information of all Cell is all transmitted on Pcell.

Particularly, for the descending sub frame of Cell being configured to FDD, if configuring Pcell on identical subframe timing according to the descending reference upstream and downstream of Pcell is descending sub frame, then the HARQ-ACK timing relationship of the descending sub frame of described FDD is that the HARQ-ACK timing relationship of the descending sub frame configured in identical subframe position according to the descending reference upstream and downstream of Pcell is determined; For the descending sub frame of CC being configured to FDD, if the identical subframe timing configured according to the descending reference upstream and downstream of Pcell is sub-frame of uplink, if according to the HARQ-ACK timing relationship of Pcell, this identical subframe there is not the corresponding sub-frame of uplink for feeding back HARQ-ACK information, then this descending sub frame being configured to FDD can not transmitting downlink data; Under this kind of mode, all cell all transmit on Pcell, but correspondingly, on the Cell of FDD configuration, part descending sub frame possibly cannot transmitting downlink data, causes certain waste of downlink resource.

Adopt this method, the HARQ-ACK feedback information of all CC is all transmitted on main CC, only needs a set of power control system, and required total transmitting power is less.

The second forms structure according to the cell that UE configures and determines that the method for the Cell of HARQ-ACK timing relationship and transmitting HARQ-ACK information is: the HARQ-ACK timing relationship that all Cell being configured to FDD all adopt the descending reference upstream and downstream of Pcell to configure; The HARQ-ACK information of all Cell is all transmitted on Pcell.

Particularly, for the descending sub frame of Cell being configured to FDD, if configuring Pcell on identical subframe timing according to the descending reference upstream and downstream of Pcell is descending sub frame, then the HARQ-ACK timing relationship of the descending sub frame of described FDD is that the HARQ-ACK timing relationship of the descending sub frame configured in identical subframe position according to the descending reference upstream and downstream of Pcell is determined; For the descending sub frame of CC being configured to FDD, if the identical subframe timing configured according to the descending reference upstream and downstream of Pcell is sub-frame of uplink A, adopt new HARQ-ACK timing relationship, such as, according to the descending up configuration of the descending reference of Pcell, the HARQ-ACK timing of this descending sub frame is determined according to the HARQ-ACK timing relationship of first descending sub frame after the sub-frame of uplink A of Pcell.

Situation 2:

The TDD configuration of Pcell to be TDD configuration or Pcell be dynamic change, the Serving cell Scell of UE is FDD configuration.

Determine that the method for the HARQ-ACK timing relationship of Scell and the cell of transmitting HARQ-ACK information being configured to FDD configuration is: the HARQ-ACK timing relationship of Scell according to TDD upstream and downstream configuration 5 being configured to FDD, and upload at Pcell the HARQ-ACK information that transmission & distribution are set to the Scell of FDD; Namely the descending sub frame 9,0,1,3,4,5,6,7,8 for the Scell being configured to FDD transmits at the sub-frame of uplink 2 of Pcell according to the HARQ-ACK timing relationship of TDD upstream and downstream configuration 5.There is not the corresponding sub-frame of uplink for feeding back HARQ-ACK information in the descending sub frame 2 for the CC being configured to FDD, then the descending sub frame 2 of FDD can not transmitting downlink data.

Another kind determines that the method for the HARQ-ACK timing relationship of Scell and the cell of transmitting HARQ-ACK information being configured to FDD configuration is: the HARQ-ACK timing relationship of Scell according to TDD upstream and downstream configuration 5 being configured to FDD, and uploads at Pcell the HARQ-ACK information that transmission & distribution are set to the Scell of FDD; Namely the descending sub frame 9,0,1,3,4,5,6,7,8 for the Scell being configured to FDD transmits at the sub-frame of uplink 2 of Pcell according to the HARQ-ACK timing relationship of TDD upstream and downstream configuration 5.In the radio frames n being configured to the Scell of FDD, the HARQ-ACK information of descending sub frame 2 is transmitted at the sub-frame of uplink 2 of next radio frames n+1 of Pcell.

As seen from the above-described embodiment, the method of the PUSCH synchronous HARQ timing relationship that the application provides, when different members carrier wave (CC) exists the situation of TDD and FDD two kinds difference configuration in carrier aggregation (CA), determine the form of the DCI of PUSCH synchronous HARQ timing relationship and scheduling PUSCH according to member carrier composition structure; And according to the timing relationship determined and DCI format, the Cell determined transmits PUSCH.Thus can various ce ll exist TDD and FDD two kinds difference configuration time, effectively realize the transmission of PUSCH.

The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment made, equivalent replacement, improvement etc., all should be included within the scope of protection of the invention.
