Description

Answer method in TDD-FDD system, base station, terminal and system
Technical field
The present invention relates to the communication technology, be specifically related to the answer method in a kind of time division duplex (Time-DivisionDuplex, TDD)-Frequency Division Duplexing (FDD) (Frequency-DivisionDuplex, FDD) system, base station, terminal and system.
Background technology
Lte-a system proposes the technology of carrier aggregation.Carrier aggregation (Carrier Aggregation, CA) is condensed together to support larger transmission bandwidth (being 100MHz to the maximum) by the carrier units (Component Carrier, CC) of 2 or more.When terminal supports carrier aggregation, just can be transmitted and receive data by multiple carrier units simultaneously, thus achieve larger transmission bandwidth.
In Rel-10 release protocol, individually introduce carrier aggregation technology for TDD and FDD, that is, terminal can support the polymerization of multiple carrier units of TDD system standard, or the polymerization of multiple carrier units of support FDD system standard.
In the Rel-12 release protocol upgraded, introduce the concept of the system combined carrier aggregation of TDD-FDD further, that is, when the system combined carrier aggregation of terminal support TDD-FDD, in the polymerization of multiple carrier units that terminal is supported, both comprised the carrier units of TDD system standard, also comprised the carrier units of FDD system standard, so that existing frequency spectrum resource can be utilized more fully.
FDD system and TDD all require that the downlink data that end-on is received feeds back, and when after correct downlink data receiving, need feedback acknowledgment to reply (Acknowledgement, ACK); When incorrect downlink data receiving, need feedback negative response (Negative-acknowledgement, NACK).But in FDD system and TDD system, the mode of feeding back ACK/NACK is different.In FDD system, terminal can both send upstream data in each subframe, therefore, is defined in first subframe after the scheduled time such as 4ms and sends ACK/NACK.In a tdd system, subframe is divided into sub-frame of uplink and descending sub frame, and terminal can only send upstream data in sub-frame of uplink, therefore, is defined in first sub-frame of uplink after the scheduled time such as 4ms and sends up ACK/NACK.When the system combined carrier aggregation of terminal support TDD-FDD, just need in a subframe, feed back the ACK/NACK response of TDD downlink data and the ACK/NACK response of FDD downlink data simultaneously.But, if when only having PUCCH to transmit on TDD carrier wave, the regulation subframe of the ACK/NACK response of feedback FDD downlink data is likely the descending sub frame of TDD standard, that is, the ACK/NACK response of FDD downlink data cannot be fed back simultaneously, thus cause the generation of contradiction.
Visible, in the prior art, when the system combined carrier aggregation of terminal support TDD-FDD, the feedback of ACK/NACK cannot be realized.

Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Embodiment 1:
The embodiment of the present invention proposes the answer method of the system combined carrier aggregation of a kind of TDD-FDD, and see Fig. 1, the method comprises:
Step 101: according to the ratio of uplink subframe to downlink subframe of TDD system, feeds back each sub-frame division in binding window at different A/N in advance.
Step 102: according to the ratio of uplink subframe to downlink subframe of TDD system, pre-sets the corresponding relation that each A/N feeds back binding window and sub-frame of uplink.
Step 103: at each sub-frame of uplink, determines that the A/N corresponding with this sub-frame of uplink feeds back and binds window.
Step 104: at each sub-frame of uplink, send/receive determined A/N and feeds back the ACK/NACK response of the TDD downlink data of all subframes in binding window and the ACK/NACK response of FDD downlink data.
In each ratio of uplink subframe to downlink subframe under TDD standard, each descending sub frame is a corresponding sub-frame of uplink, this kind of correspondence shows that this sub-frame of uplink is the subframe of the ACK/NACK of these descending sub frame data of feedback.According to above-mentioned Fig. 1, flow process can be found out, the embodiment of the present invention is according to this kind of corresponding relation, each sub-frame division in ratio of uplink subframe to downlink subframe is fed back in binding window at different A/N, and the corresponding relation that each A/N feeds back binding window and sub-frame of uplink is set, like this, just make each subframe (no matter being the sub-frame of uplink of TDD or the descending sub frame of TDD) can a corresponding sub-frame of uplink, because FDD may have up-downgoing data to send in each subframe, that is, all need feeding back ACK/NACK, therefore, the embodiment of the present invention ensure that each subframe can after a corresponding sub-frame of uplink, just can ensure when the system combined carrier aggregation of terminal support TDD-FDD, the TDD downlink data that each subframe sends and/or FDD downlink data, corresponding sub-frame of uplink can be found to carry out ACK/NACK response, namely, the ACK/NACK response of TDD downlink data and the ACK/NACK response of FDD downlink data can be fed back simultaneously, thus achieve the feedback of ACK/NACK.
The answer method of the system combined carrier aggregation of the TDD-FDD shown in above-mentioned Fig. 1, can be applied in terminal, now, in above-mentioned steps 104, be at each sub-frame of uplink, send determined A/N and feed back the ACK/NACK response of the TDD downlink data of all subframes in binding window and the ACK/NACK response of FDD downlink data.Certainly, the answer method of the system combined carrier aggregation of the TDD-FDD shown in above-mentioned Fig. 1, also can be applied in base station, now, in above-mentioned steps 104, be at each sub-frame of uplink, receive determined A/N and feed back the ACK/NACK response of the TDD downlink data of all subframes in binding window and the ACK/NACK response of FDD downlink data.Certainly, said method can also be utilized respectively by base station and terminal, coordinate the answering of the system combined carrier aggregation of TDD-FDD.
For the implementation procedure of step 101 in above-mentioned Fig. 1, need to ensure that each subframe (no matter being the sub-frame of uplink of TDD or the descending sub frame of TDD) can a corresponding sub-frame of uplink (so that based on the A/N response of this sub-frame of uplink feedback TDD downlink data and/or A/N response of FDD downlink data), the mode that concrete formation A/N feeds back binding window is various, enumerates two kinds of preferably implementations below:
Mode one, ratio of uplink subframe to downlink subframe according to TDD system, for each sub-frame of uplink, be divided in same A/N and feed back and bind in window by this sub-frame of uplink and first descending sub frame thereafter; For descending sub frame, by each descending sub frame of same for correspondence sub-frame of uplink, be divided in same A/N and feed back in binding window.
This kind of mode one is applicable to each ratio of uplink subframe to downlink subframe of TDD system, any one namely in ratio of uplink subframe to downlink subframe 0 ~ 6.
Mode two, ratio of uplink subframe to downlink subframe according to TDD system, if the sub-frame of uplink that adjacent two descending sub frames are corresponding different, and when there is multiple sub-frame of uplink between these two adjacent descending sub frames, a setting sub-frame of uplink and previous descending sub frame before in the plurality of sub-frame of uplink are divided in same A/N and feed back and bind in window; And sub-frame of uplink remaining in the plurality of sub-frame of uplink and a rear descending sub frame be divided in same A/N and feed back and bind in window.For descending sub frame, by each descending sub frame of same for correspondence sub-frame of uplink, be divided in same A/N and feed back in binding window.
Preferably, in this implementation two, consider the feature of ratio of uplink subframe to downlink subframe 0, ratio of uplink subframe to downlink subframe 1 or ratio of uplink subframe to downlink subframe 6, the length of window of the A/N feedback binding window that it divides is less, therefore, this implementation two is more suitable for ratio of uplink subframe to downlink subframe 0, ratio of uplink subframe to downlink subframe 1 or ratio of uplink subframe to downlink subframe 6.
This kind of implementation two, achieves the subframe average mark that need feed back and be dispersed in different A/N feedback binding windows, thus the bit number that subframe is fed back more is tending towards average.

In embodiments of the present invention, according to the feature of ratio of uplink subframe to downlink subframe, such as, for ratio of uplink subframe to downlink subframe 0,1,6, in above-mentioned steps 104, the ACK/NACK of the descending sub frame in A/N feedback binding window can be replied the position be placed on before sub-frame of uplink, that is, ensure the ACK/NACK response of first feeding back actual downstream subframe in a subframe, thus ensure that base station correctly can parse ACK/NACK response further.
In order to clearly embody the implementation procedure of the embodiment of the present invention, feeding back two modes of binding window below for above-mentioned division A/N, lifting an object lesson respectively and being described.
Embodiment 2:
The present embodiment 2 feeds back the mode one of binding window for above-mentioned division A/N, for the process of end side, the response implementation procedure of the system combined carrier aggregation of TDD-FDD is described.See Fig. 2, this process specifically comprises:
Step 201: in advance according to the ratio of uplink subframe to downlink subframe of the TDD system of current use, for each sub-frame of uplink, is divided in same A/N and feeds back and bind in window by this sub-frame of uplink and first descending sub frame thereafter.
Step 202: in advance according to the ratio of uplink subframe to downlink subframe of the TDD system of current use, for descending sub frame, by each descending sub frame of same for correspondence sub-frame of uplink, is divided in same A/N and feeds back in binding window.
The sub-frame of uplink that in step 202, descending sub frame is corresponding, refers to the ACK/NACK response that this sub-frame of uplink can feed back this descending sub frame.
The fixing sequencing that above-mentioned steps 201 does not perform with step 202, and be applicable to any one ratio of uplink subframe to downlink subframe of TDD, i.e. ratio of uplink subframe to downlink subframe 0 ~ 6.
By the process of step 201 with step 202, then define different A/N feedback binding windows, each subframe is divided in each A/N and feeds back in binding window.The length of A/N feedback binding window is more than or equal to 1.
Such as, see Fig. 3, for the ratio of uplink subframe to downlink subframe 0 of TDD, subframe 0,1,5,6 is descending sub frame, subframe 0,1, and the sub-frame of uplink of the feeding back ACK/NACK response message of 5 correspondences is respectively the subframe 4,7,9 in this frame; The sub-frame of uplink of the feeding back ACK/NACK response message of subframe 6 correspondence is the subframe 2 in next frame.According to the process of above-mentioned steps 201 and step 202, then subframe 6 can be divided in an A/N feedback binding window (being designated as A/N feedback binding window 1), by subframe 7, 8, 9 are divided in an A/N with first subframe 0 thereafter feeds back and binds in window (be designated as A/N feed back bind window 2), subframe 1 is divided in an A/N feedback binding window (being designated as A/N feedback binding window 3), by subframe 2, 3, 4 are divided in an A/N with first descending sub frame 5 thereafter feeds back and binds in window (be designated as A/N feed back bind window 4), therefore, for ratio of uplink subframe to downlink subframe 0, 4 A/N feedback binding windows can be formed.These 4 A/N feedback binding windows are simultaneously for TDD and FDD.
In like manner, for the ratio of uplink subframe to downlink subframe 1 ~ 6 of TDD, according to the process in above-mentioned steps 201 and step 202, be then divided into the A/N feedback binding window under each ratio of uplink subframe to downlink subframe as shown in Fig. 4 ~ Fig. 9 respectively.
Step 203: in advance according to the ratio of uplink subframe to downlink subframe of the TDD system of current use, pre-sets each A/N and feeds back binding window and the corresponding relation for the sub-frame of uplink of feeding back response information.
Here, according to the corresponding relation between the descending sub frame of the ratio of uplink subframe to downlink subframe defined of former TDD and the sub-frame of uplink feeding back its response message, obtain in this step, each A/N feeds back binding window and the corresponding relation for the sub-frame of uplink of feeding back response information.Illustrate each A/N see arrow in Fig. 3 ~ Fig. 9, figure and feed back binding window and the corresponding relation for the sub-frame of uplink of feeding back response information.
Step 204: terminal, according to the system combined carrier aggregation of TDD-FDD of configuration, receives the downlink data of TDD and the downlink data of FDD of base station transmission at each descending sub frame.
Step 205: terminal, at each sub-frame of uplink, is determined that the A/N corresponding with this sub-frame of uplink feeds back and bound window.
Step 206: terminal detects the ratio of uplink subframe to downlink subframe of current use, if ratio of uplink subframe to downlink subframe 0, ratio of uplink subframe to downlink subframe 1 or ratio of uplink subframe to downlink subframe 6, then perform step 207, if ratio of uplink subframe to downlink subframe 2, ratio of uplink subframe to downlink subframe 3, ratio of uplink subframe to downlink subframe 4 or ratio of uplink subframe to downlink subframe 5, then perform step 209.
Step 207: for all subframes in determined A/N feedback binding window, the ACK/NACK of the wherein TDD downlink data of descending sub frame reply the position be placed on before sub-frame of uplink, is then that the ACK/NACK of FDD downlink data replys.
The process of this step, the ACK/NACK response of TDD downlink data is placed on before sub-frame of uplink ACK/NACK state to use ACK/NACK mapping table to feed back.
Step 208:RRC signaling can configure the form 1b using PUCCH to be with Channel assignment, sends determined A/N and feeds back the ACK/NACK response of the TDD downlink data of all subframes in binding window and the ACK/NACK response of FDD downlink data, terminate current process.
Step 209:RRC signaling can configure and use PUCCH format 3, sends determined A/N and feeds back the ACK/NACK response of the TDD downlink data of all subframes in binding window and the ACK/NACK response of FDD downlink data.
The process of above-mentioned steps 205 to step 208 can be exemplified as: for current use ratio of uplink subframe to downlink subframe 1, such as in subframe 3, see Fig. 4, subframe 3 is sub-frame of uplink, the A/N corresponding with this sub-frame of uplink 3 feeds back that to bind window be subframe 7 ~ 9 in previous frame, so, then determine that the A/N corresponding with this subframe 3 feeds back to bind window and bind window for the A/N of second shown in Fig. 4 feeds back.Be sub-frame of uplink because this A/N feeds back the first two in binding window, last is only descending sub frame, therefore, needs before being placed on the ACK/NACK of descending sub frame 9 response, then by after being placed on the ACK/NACK response of sub-frame of uplink 7 and 8.Then, in subframe 9,7, the ACK/NACK response of the downlink data of the TDD received on 8 and the ACK/NACK response of FDD downlink data, send to base station by the form 1b of PUCCH band Channel assignment.
Flow process shown in above-mentioned Fig. 2 is described for terminal process then.
For base station side, shown in its processing mode with Fig. 2, flow process is identical, only needs to do adaptability revision.Such as, in step 204, base station, according to the system combined carrier aggregation of TDD-FDD of configuration, sends the downlink data of TDD and the downlink data of FDD at each descending sub frame.The subject of step 205 and step 206 is base station.In step 207 to step 208, base station uses PUCCH to be with the form 1b of Channel assignment, receive determined A/N and feed back the ACK/NACK response of the TDD downlink data of all subframes in binding window and the ACK/NACK response of FDD downlink data, and, for the ACK/NACK response received, the position of foremost is the response of the actual downstream subframe after adjustment.In step 209, use PUCCH format 3, receive determined A/N and feed back the ACK/NACK response of the TDD downlink data of all subframes in binding window and the ACK/NACK response of FDD downlink data.
