For frequency division multiplexing; Minimizing along with the WiMAX number of users; When the bandwidth that will distribute to WiMAX when 10MHz is reduced to 5MHz, consider that part WiMAX existing network terminal do not support the 5MHz/10MHz adaptive scanning, so frequency division multiplexing can't compatible well this part terminal; In addition, along with the further minimizing of WiMAX number of users,, WiMAX still can cause the waste of valuable frequency spectrum resource for distributing the carrier wave of 5MHz.

For the interframe multiplexing scheme, though the interframe multiplexing scheme can come to adjust flexibly WiMAX and the shared time resource of LTE TDD as required.But LTE TDD has the strict automatic repeat requests of mixing (Hybrid Automatic Repeat Request; Hereinafter to be referred as: the HARQ) definition of sequential relationship.Among the LTE TDD, the synchronous HARQ transmission means is adopted in the transmission of uplink data channels, and for certain uplink data channels transmission, its corresponding base station feedback confirms/deny that the moment of response message and the moment of uplink data channels re-transmission next time all fix; Though downstream data channel adopts asynchronous HARQ transmission means, for the transmission of certain downstream data channel, its corresponding user feedback confirms/denies that the moment of response message also fixes.If these corresponding fixed times are allocated for WiMAX transmission, will destroy the HARQ sequential relationship of LTE TDD system so, making can not compatible well LTE user on WiMAX and the LTE TDD mixed carrier.

Consider in radio frames; The number of sub-frames that is used for downlink transfer also can dispose with the number of sub-frames that is used for uplink; Descending sub frame that provides in the associative list 2 and the setting of sub-frame of uplink proportioning; Can be according to ratio of uplink subframe to downlink subframe, be provided with in the radio frames the 1st, or the 1st and the 6th sub-frame be special subframe.In special subframe, DwPTS partly is used for downlink transfer, and the GP part is idle, and UpPTS partly is used for uplink.The total length of DwPTS, GP and UpPTS is fixed as 1ms, and the length of every part also can dispose.In the special subframe, DwPTS can send downlink data, but UpPTS can not send upstream data, so special subframe also can be regarded as a special descending sub frame.

Table 2

Be provided with based on the WiMAX of above-mentioned introduction and the frame structure and the descending/sub-frame of uplink proportioning of LTE TDD system; The present invention adopts the mode of mixed carrier; Through frame structure is carried out appropriate configurations, to realize the smooth evolution of WiMAX system to LTE TDD system, concrete scheme is following:

Fig. 1 c is the flow chart of the data transmission method that provides of one embodiment of the invention, and shown in Fig. 1 c, this data transmission method can comprise:

Step 11, LTE TDD subscriber terminal equipment receive downlink data or the signaling that network equipment sends through the LTE TDD descending sub frame on WiMAX and the LTETDD mixed carrier, and wherein said LTETDD descending sub frame comprises the 0th, 1,5 and 6 subframes of each radio frames at least.

In the present embodiment, there is the mixed carrier of at least one WiMAX and LTE TDD in the system.In WiMAX and the LTE TDD mixed carrier, the WiMAX system uses identical carrier wave with LTE TDD system, but taking different time respectively transmits.The wireless frame length of LTE TDD system is 10ms, and the frame length of WiMAX system is 5ms.On WiMAX and LTE TDD mixed carrier, LTETDD subscriber terminal equipment and WiMAX subscriber terminal equipment come regularly promptly can have two reference times through LTE TDD radio frames and WiMAX frame respectively.In embodiments of the present invention, for describing conveniently, unified selection LTE TDD radio frames regularly is used as the reference time, and this radio frames is the 10ms radio frames of LTE TDD.

LTE TDD subscriber terminal equipment is meant the subscriber terminal equipment of supporting LTE TDD standard at least.Except supporting LTE TDD standard, can also support other standard, for example WiMAX simultaneously.

In order to keep the HARQ sequential relationship of LTE TDD system, the resource that WiMAX system and LTE TDD system take in time is the multiple of LTE TDD system subframe long (1 millisecond).But following situation can make an exception; For 1 millisecond of resource of distributing as LTE TDD special subframe; If 1 millisecond of resource of this LTE TDD special subframe back is the WiMAX ascending resource; The part that this LTE TDD special subframe UpPTS is corresponding so also can be used as the WiMAX uplink except as the UpPTS of LTE TDD.

In the radio frames of LTE TDD system; The number of sub-frames that is used for downlink transfer can dispose with the number of sub-frames that is used for uplink; Descending sub frame and the setting of sub-frame of uplink proportioning that the LTE TDD system that provides according to table 2 supports, wherein D, U and S represent descending sub frame, sub-frame of uplink and special subframe respectively.For LTE TDD system, in each 10ms radio frames, the 0th, 1,5 and 6 subframes have been carried synchronizing channel and physical layer broadcast channel, be used for the user synchronously, Cell searching and obtain system information.Can see that from table 2 in LTE TDD system, the 0th subframe and the 5th subframe are descending sub frames, the 1st subframe is a special subframe, and the 6th subframe can be descending sub frame or special subframe.This part resource is necessary for the compatible LTE TDD of mixed carrier subscriber equipment; Therefore present embodiment keeps LTE TDD system at least and is used as descending sub frame and special subframe in the 0th, 1,5 and 6 subframes of each 10ms radio frames in WiMAX and LTE TDD mixed carrier.Certainly except 0,1,5 and 6 subframes, also can keep the descending sub frame resource of more subframes in WiMAX and the LTE TDD mixed carrier as LTE TDD.

Wherein, descending sub frame can transmitting downlink data or signaling, and special subframe comprises DwPTS, GP and UpPTS.In special subframe, DwPTS is used for downlink transfer, and GP is idle, and UpPTS is used for uplink.The total length of DwPTS, GP and UpPTS is fixed as 1ms, and the length of every part also can dispose.In the special subframe, DwPTS can send downlink data, but UpPTS can not send upstream data, so special subframe can be regarded as a special descending sub frame.Therefore; In the present embodiment; LTE TDD subscriber terminal equipment receives downlink data or the signaling that network equipment sends through the LTE TDD descending sub frame on WiMAX and the LTE TDD mixed carrier, and wherein said LTE TDD descending sub frame comprises the 0th, 1,5 and 6 subframes of each radio frames at least.LTE TDD subscriber terminal equipment just can insert WiMAX and LTE TDD mixed carrier through receiving synchronizing channel and the physical layer broadcast channel that the 0th, 1,5 and 6 subframes are carried, and communicates by letter with network equipment according to LTE TDD system regulation.

Step 12, LTE TDD subscriber terminal equipment send upstream data or signaling at the sub-frame of uplink of said WiMAX and LTE TDD mixed carrier to network equipment.Wherein said sub-frame of uplink is that the ratio of uplink subframe to downlink subframe according to LTE TDD system is provided with, and is used for feeding back the corresponding response message of at least one subframe with said LTE TDD descending sub frame.

In the LTE TDD system,,, stipulated the sub-frame of uplink of corresponding user feedback response message for the transfer of data of certain descending sub frame according to the ratio of uplink subframe to downlink subframe of LTE TDD system; For the transfer of data of certain sub-frame of uplink, the descending sub frame of corresponding base station feedback response message and the sub-frame of uplink of data re-transmission have also been stipulated.

In WiMAX and the LTE TDD mixed carrier; For the HARQ sequential relationship of keeping LTE TDD with compatible LTE TDD user better, particularly only support the for example user of version 8 and version 9 of LTE TDD earlier version; According to the ratio of uplink subframe to downlink subframe of LTE TDD system, the subframe of feeding back uplink response message that can be corresponding with at least one LTE TDD descending sub frame or special subframe is set to the sub-frame of uplink of LTETDD system.That is to say; In the present embodiment; LTE TDD sub-frame of uplink can be set according to the ratio of uplink subframe to downlink subframe of LTE TDD system, and LTE TDD subscriber terminal equipment is at the response message of LTE TDD sub-frame of uplink to the network equipment feeding back downlink subframe correspondence of LTE TDD system.

In the LTE TDD system, physical layer HARQ technology is supported in the transmission of data and reception, to reduce data transmission delay and to obtain higher message transmission rate.In the HARQ technology, the data receiver need feed back response message to data receiver, to help confirming whether data correctly receive.If Data Receiving is correct, then to data receiver feedback acknowledgment response message; If the Data Receiving mistake is then denied response message to the data receiver feedback.Therefore, can also utilize HARQ to retransmit subframe retransmits the sub-frame of uplink data carried by data.The ascending HARQ corresponding in the transfer of data of sub-frame of uplink retransmits subframe transmit ascending data or signaling.

The method of present embodiment can also comprise: LTE TDD subscriber terminal equipment retransmits on the subframe at HARQ and sends upstream data or signaling to network equipment, and HARQ wherein retransmits subframe and is used for the sub-frame of uplink data carried by data is retransmitted.

Just realized sending the purpose of upstream data to the network equipment of LTE TDD system through said method.

At down direction, the WiMAX subscriber terminal equipment can receive downlink data or the signaling that the network equipment of WiMAX system sends through the downlink resource that is not used by said LTE TDD system in said WiMAX and the LTE TDD mixed carrier;

At up direction, the WiMAX subscriber terminal equipment sends upstream data or signaling through the ascending resource that is not used by said LTE TDD system in said WiMAX and the LTE TDD mixed carrier to network equipment.

Carry out transfer of data through said method, just can realize the smooth evolution of WiMAX system to LTE TDD system.

In the embodiment of the invention; The downlink data or the signaling of the 0th, 1, the 5 and 6 subframes transmission that keeps at least in the network equipment that LTE TDD subscriber terminal equipment can receive LTE TDD system each radio frames through WiMAX and LTE TDD mixed carrier; Because the 0th, 1,5 and 6 subframes as the resource of transmission LTE TDD user data, are made that mixed carrier can compatible LTE TDD user terminal.Because mixed carrier can transmit the data of WiMAX and LTE TDD system simultaneously; Therefore; Through adopting the mode of WiMAX and LTE TDD mixed carrier; Make the network equipment of WiMAX system and LTE TDD system can both receive data carried by data on the mixed carrier, realized that WiMAX system and LTE TDD system coexist on same carrier wave, and can compatible well LTE TDD user on WiMAX and the LTE TDD mixed carrier.Realized the smooth evolution of WiMAX system to LTE TDD system.

In the data transmission method that another embodiment of the present invention provides; For mixed carrier; In order when to LTETDD user favorable compatibility being provided, to keep the high efficiency utilization of resources, the subframe with LTE TDD descending sub frame of being withed a hook at the end and the pairing feeding back uplink response message of special subframe in the present embodiment all is set to LTE TDD sub-frame of uplink.That is, for the LTE TDD descending sub frame resource that keeps, the up moment of the response message that feedback is corresponding with these descending sub frames is arranged to LTE TDD sub-frame of uplink; For the LTE TDD special subframe resource that keeps, if its DwPTS also can send downlink data, the up moment of the response message that feedback is corresponding with special subframe is arranged to LTE TDD sub-frame of uplink.This moment, WiMAX and LTE TDD mixed carrier can not rely on other carrier wave and independent the existence.

Present embodiment is 1 with LTE TDD system ratio of uplink subframe to downlink subframe, promptly consists of example with each 5ms field by two descending sub frames, a special subframe and two sub-frame of uplink and further specifies the scheme of WiMAX of the present invention to LTE TDD evolution.In following examples, all regularly the time describes as a reference with the 10ms radio frames of LTE TDD.

When the proportioning of sub-frame of uplink, special subframe and descending sub frame in the radio frames of said LTE TDD system is 2: 1: 2, at the network equipment feeding back uplink response message of the corresponding sub-frame of uplink of said the 0th, 1,5 and 6 subframes to said LTE TDD system.For WiMAX and LTE TDD mixed carrier, at first keep the 0th, 1,5 and 6 subframes as LTE TDD resource.To the 0th and 1 subframe of current wireless frame, its corresponding response message is in the 7th subframe feedback of current wireless frame; To the 5th, 6 subframes of current wireless frame, its corresponding response message is in the 2nd subframe feedback of the next radio frames of current wireless frame.

Referring to Fig. 2 a is the method flow diagram of the transfer of data that provides of another embodiment of the present invention, and the method for present embodiment comprises:

Step 21, LTE TDD subscriber terminal equipment receive downlink data or the signaling that network equipment sends through the 0th, 1,5 and 6 subframes of each radio frames on WiMAX and the LTETDD mixed carrier.

When LTE TDD sub-frame of uplink was set, the subframe of the feeding back uplink response message that the LTE TDD descending sub frame of being withed a hook at the end and special subframe is corresponding all was set to LTE TDD sub-frame of uplink.According to response message feedback constantly, with the 2nd and 7 subframes of a radio frames sub-frame of uplink resource as LTE TDD.For the 2nd and 7 subframes of current wireless frame, its corresponding HARQ retransmission time is respectively in the 2nd and the 7th subframe of next radio frames, thereby new LTE TDD sub-frame of uplink resource need be set in the 10ms radio frames.In the 10ms radio frames, the 0th, 1,2,5,6 and 7 subframes just are arranged for the resource of LTE TDD system transmissions, and the 3rd, 4,8 and 9 remaining subframes can be arranged for the resource of WiMAX system transmissions.Consider that the 4th and 9 interior subframes of 10ms radio frames are used for downlink transfer according to the sub-frame allocation of LTETDD, so can be arranged for the resource of WiMAX downlink transfer; The 3rd and 8 subframes are used for uplink according to the sub-frame allocation of LTE TDD, so can be arranged for the resource of WiMAX uplink.

Need to prove that for the WiMAX transmission, first symbol in its 5ms frame is used for pilot transmission, belongs to the downlink resource of WiMAX.For LTE TDD system, the 0th subframe in its 10ms radio frames is a descending sub frame.To a moment,, can not also be assigned with downlink resource simultaneously as WiMAX distributing as behind the LTE TDD downlink resource.Frame head is that the subscriber terminal equipment that is respectively applied for to LTE TDD and WiMAX provides regularly.The 0th subframe of LTE TDD radio frames is a downlink frame, and the primary sign of WiMAX frame also is a downlink resource.In order to satisfy these requirements, the frame head of the frame head of WiMAX frame and LTE tdd frame can not align, because a moment can not both be divided the downlink transfer that manufactures LTE TDD, also divides the downlink transfer that manufactures WiMAX simultaneously.Thereby on mixed carrier, the frame head of the 10ms radio frames of the 5ms frame of WiMAX and LTE TDD system can not align, and can have a frame head biasing.

The start-up portion of considering each 5ms frame of WiMAX is used for downlink transfer, and WiMAX 5ms frame head can have the frame head biasing of 1ms in advance with respect to the wireless frame head of the 10ms of LTE TDD, postpones the frame head biasing of 4ms or 9ms in other words.WiMAX on mixed carrier and LTE TDD resource allocation conditions are shown in Fig. 2 b.In the WiMAX system in the evolution of TDD LTE system, when the proportioning of sub-frame of uplink, special subframe and descending sub frame in the radio frames of LTE TDD system is 2: 1: 2.In the 10ms of LTETDD system radio frames, the 0th～9 subframe is set is followed successively by LTE TDD descending sub frame, LTE TDD special subframe, LTE TDD sub-frame of uplink, WiMAX ascending resource, WiMAX downlink resource, LTE TDD descending sub frame, LTE TDD special subframe, LTE TDD sub-frame of uplink, WiMAX ascending resource and WiMAX downlink resource; The frame head of WiMAX 5ms frame has the frame head biasing that shifts to an earlier date 1ms, delay 4ms or postpone 9ms with respect to the frame head of LTE TDD 10ms radio frames.In the example of Fig. 2 b; Except WiMAX and LTE TDD mixed carrier; Also there is an independently LTE TDD carrier wave; Can see that the LTE TDD resource on the mixed carrier has identical frame regularly with LTE TDD carrier wave, and the uplink and the downlink transfer of mixed carrier and LTE TDD carrier wave are all alignd respectively.

Step 22, LTE TDD subscriber terminal equipment send upstream data or signaling through the 2nd and 7 subframes of each radio frames on WiMAX and the LTE TDD mixed carrier to network equipment.

Particularly, for the corresponding up response message of downlink data that the 0th subframe and the 1st subframe of current wireless frame are sent, LTE TDD subscriber terminal equipment feeds back to network equipment on the 7th subframe of current wireless frame; For the corresponding up response message of downlink data that the 5th subframe and the 6th subframe of current wireless frame are sent, LTE TDD subscriber terminal equipment feeds back to network equipment on the 2nd subframe of next radio frames of current wireless frame.

It is the 2nd subframe of next radio frames that the ascending HARQ corresponding with the 2nd subframe of current wireless frame retransmits subframe; It is the 7th subframe of next radio frames that the ascending HARQ corresponding with the 7th subframe of current wireless frame retransmits subframe.

Just realized sending upstream data or signaling through said method to the network equipment of LTE TDD system.

At down direction, the WiMAX subscriber terminal equipment receives downlink data or the signaling that network equipment sends through the 4th subframe and the 9th subframe of each radio frames in said WiMAX and the LTE TDD mixed carrier.

At up direction, the WiMAX subscriber terminal equipment sends upstream data or signaling through the 3rd subframe and the 8th subframe of each radio frames in said WiMAX and the LTE TDD mixed carrier to network equipment.

Except WiMAX and LTE TDD mixed carrier, can also there be independently LTE TDD carrier wave and/or WiMAX carrier wave in the system.When independently WiMAX carrier wave and/or WiMAX carrier wave with mixed carrier during in identical or nearby frequency bands, uplink between these carrier waves and downlink transfer should be alignd respectively, to avoid interfering with each other between the up-downgoing transmission.

In the present embodiment; The downlink data or the signaling of the 0th, 1, the 5 and 6 subframes transmission that keeps at least in the network equipment that LTE TDD subscriber terminal equipment can receive LTE TDD system each radio frames through WiMAX and LTE TDD mixed carrier; Because the 0th, 1,5 and 6 subframes as the resource of transmission LTE TDD user data, are made that mixed carrier can compatible LTE TDD user terminal.And the subframe of LTE TDD descending sub frame of being withed a hook at the end and the pairing feeding back uplink response message of special subframe all is set to LTE TDD sub-frame of uplink; Realizing that WiMAX system and LTE TDD system coexist on same carrier wave when, make that WiMAX can not rely on other carrier wave with LTE TDD mixed carrier and the independence existence in the communication system.

In order to reduce the shared resource of LTE TDD system uplink subframe in WiMAX and the LTE TDD mixed carrier; When in the system except mixed carrier; Also have one at least independently during LTE TDD carrier wave, the subframe of the feeding back uplink response message that partial L TE TDD descending sub frame that can only keep on the mixed carrier or special subframe are corresponding is set to LTE TDD sub-frame of uplink.Owing in mixed carrier, do not have ascending resource to come the feeding back uplink response message probably, can come feeding back uplink response message on independent LTE TDD carrier wave through carrier aggregation.

In the data transmission method that further embodiment of this invention provides; For mixed carrier; In order WiMAX user to be provided maximum up covering; Present embodiment is when being provided with LTE TDD sub-frame of uplink, and the subframe of the feeding back uplink response message that partial L TE TDD descending sub frame that keeps or special subframe are corresponding is set to LTE TDD sub-frame of uplink.

When the proportioning of sub-frame of uplink, special subframe and descending sub frame in the radio frames of said LTE TDD system was 2: 1: 2, the corresponding sub-frame of uplink of the part subframe in said the 0th, 1,5 and 6 subframes was to the network equipment feeding back uplink response message of said LTE TDD system.There is 1 millisecond in advance in the frame head of said WiMAX system wireless frame, postpones 4 milliseconds or postpone 9 milliseconds frame head biasing with respect to the frame head of said LTE TDD system wireless frame.
