The preferred embodiment of the present invention is described in detail with reference to the accompanying drawings of the specification, it should be understood that this place The preferred embodiment of description only for the purpose of illustrating and explaining the present invention and is not intended to limit the present invention, and the case where not conflicting Under, the features in the embodiments and the embodiments of the present application can be combined with each other.
Refering to shown in Fig. 2A, the embodiment of the present invention proposes a kind of data communications method, and process is as follows:
Step 200: communication equipment determines radio frames, and the frame length of radio frames is related to the first HARQ timing length, radio frames Ratio of uplink subframe to downlink subframe it is related to frame length；
Step 210: communication equipment is sent or is received data using determining wireless frame structure.
The frame length of radio frames mentioned in the embodiment of the present invention is specially the quantity for the subframe that a radio frames include, example Such as, a radio frames include 8 subframes, then the frame length of radio frames is 8；One radio frames includes 4 subframes, then the frame of radio frames A length of 4, above-mentioned to be only illustrated so that the sub-frame number that a radio frames include is 8 and 4 as an example, it's not limited to that.
The first HARQ timing length mentioned in the embodiment of the present invention is specifically, receive the subframe of downlink data and right The downlink data carries out the sub-frame number of the subframe of HARQ feedback apart, for example, communication equipment is in the case where the n-th+0 subframe receives Row data, if carrying out HARQ feedback in the downlink data that the n-th+4 subframe docking receive, the first HARQ timing length is 4；It is logical Believe that equipment receives downlink data in the n-th+0 subframe, if it is anti-to carry out HARQ in the downlink data that the n-th+8 subframe docking receive Feedback, then the first HARQ timing length is 8, above-mentioned to be only illustrated so that the first HARQ timing length is 8 and 4 as an example and unlimited Due to this.
In practical applications, uplink retransmission timing length need be equal to HARQ timing length, therefore, in order to improve retransmit at Power and retransmission efficiency, in the embodiment of the present invention, optionally, the frame lengths of radio frames is equal to the first HARQ timing length and multiplies with 2 Product.
Re-transmission timing length mentioned in the embodiment of the present invention is specifically, receiving the subframe of downlink data and weighing for the first time The sub-frame number of the subframe of the downlink data apart is newly transmitted, for example, communication equipment receives lower line number in the n-th+0 subframe According to if downlink data transmission failure, transmits the downlink data in the n-th+4 subframes again for the first time, then retransmitting timing length is 4； Communication equipment receives downlink data in the n-th+0 subframe, if downlink data transmission fails, the n-th+8 subframes for the first time again Transmit the downlink data, then retransmitting timing length is 8, it is above-mentioned to be only illustrated for retransmitting timing length and being 8 and 4, and It is not limited to this.
It needs to be equal to HARQ timing length to uplink retransmission timing length below to illustrate.
For example, communication equipment receives downlink data in the n-th+0 subframe, if in the case where the n-th+4 subframe docking receive Row data carry out HARQ feedback, if the downlink data transmission fails, need to transmit the lower line number again in the n-th+8 subframes According to；Communication equipment receives downlink data in the n-th+0 subframe, if carrying out in the downlink data that the n-th+8 subframe docking receive HARQ feedback needs to transmit the downlink data again in the (n+1)th 6 subframes if the downlink data transmission fails.
Another example is: the first HARQ timing length is 4, then retransmitting timing length is also 4, at this point, the frame length of radio frames is 8, As shown in Figure 2 B, if the first HARQ timing length is 2, retransmitting timing length is also 2, at this point, the frame length of radio frames is 4, As shown in Figure 2 C.
Specifically, be used for the subframe of uplink, uplink can be with for sub-frame of uplink mentioned in the embodiment of the present invention It is just passed for uplink, or uplink retransmission.
Similarly, the downlink subframe mentioned in the embodiment of the present invention is specifically, be used for the subframe of downlink transfer, downlink transfer It can just be passed for downlink, or downlink retransmits.
The attribute of radio frames further includes the proportion of ascending-descending subframes in radio frames other than including the frame length of radio frames. Therefore, the case where meeting the first HARQ timing length is only needed for communication equipment, the embodiment of the present invention is it is further proposed that one kind Optional ratio of uplink subframe to downlink subframe, specifically: the ratio of uplink subframe to downlink subframe of radio frames is m: (n-m), and m is the number of sub-frame of uplink Amount, (n-m) be downlink subframe quantity, m be more than or equal to 0, and be less than or equal to frame length integer, n is frame length.
Wherein, when a radio frames include m sub-frame of uplink and when (n-m) a downlink subframe, i.e. the uplink and downlink of radio frames Subframe proportion is m: when (n-m), the ratio of uplink subframe to downlink subframe of radio frames is specifically as follows following several forms:
N: 0, (n-1): 1, (n-2): 2, (n-3): 3 ..., 1: (n-1), 0: n wherein, and n is frame length.
For example, the frame length of radio frames is 4 when the first HARQ timing length is 2；At this point, including 0 uplink in radio frames Subframe, 4 downlink subframes, i.e., the ratio of uplink subframe to downlink subframe of one radio frames are 0: 4；Alternatively, including 1 uplink in radio frames Frame, 3 downlink subframes, i.e., the ratio of uplink subframe to downlink subframe of one radio frames are 1: 3；Alternatively, including 2 uplink in radio frames Frame, 2 downlink subframes, i.e., the ratio of uplink subframe to downlink subframe of one radio frames are 2: 2；Alternatively, including 3 uplink in radio frames Frame, 1 downlink subframe, i.e., the ratio of uplink subframe to downlink subframe of one radio frames are 3: 1；Alternatively, including 4 uplink in radio frames Frame, 0 downlink subframe, i.e., the ratio of uplink subframe to downlink subframe of one radio frames are 4: 0.
In another example the frame length of radio frames is 6 when the first HARQ timing length is 3；At this point, including on 0 in radio frames Row subframe, 6 downlink subframes, i.e., the ratio of uplink subframe to downlink subframe of one radio frames are 0: 6；Alternatively, including 1 uplink in radio frames Subframe, 5 downlink subframes, i.e., the ratio of uplink subframe to downlink subframe of one radio frames are 1: 5；Alternatively, including 2 uplink in radio frames Frame, 4 downlink subframes, i.e., the ratio of uplink subframe to downlink subframe of one radio frames are 2: 4；Alternatively, including 3 uplink in radio frames Frame, 3 downlink subframes, i.e., the ratio of uplink subframe to downlink subframe of one radio frames are 3: 3；Alternatively, including 4 uplink in radio frames Frame, 2 downlink subframes, i.e., the ratio of uplink subframe to downlink subframe of one radio frames are 4: 2；Alternatively, including 5 uplink in radio frames Frame, 1 downlink subframe, i.e., the ratio of uplink subframe to downlink subframe of one radio frames are 5: 1；Alternatively, including 6 uplink in radio frames Frame, 0 downlink subframe, i.e., the ratio of uplink subframe to downlink subframe of one radio frames are 6: 0.
In another example the frame length of radio frames is 8 when the first HARQ timing length is 4；At this point, including on 0 in radio frames Row subframe, 8 downlink subframes, i.e., the ratio of uplink subframe to downlink subframe of one radio frames are 0: 8；Alternatively, including 1 uplink in radio frames Subframe, 7 downlink subframes, i.e., the ratio of uplink subframe to downlink subframe of one radio frames are 1: 7；Alternatively, including 2 uplink in radio frames Frame, 6 downlink subframes, i.e., the ratio of uplink subframe to downlink subframe of one radio frames are 2: 6；Alternatively, including 3 uplink in radio frames Frame, 5 downlink subframes, i.e., the ratio of uplink subframe to downlink subframe of one radio frames are 3: 5；Alternatively, including 4 uplink in radio frames Frame, 4 downlink subframes, i.e., the ratio of uplink subframe to downlink subframe of one radio frames are 4: 4；Alternatively, including 5 uplink in radio frames Frame, 3 downlink subframes, i.e., the ratio of uplink subframe to downlink subframe of one radio frames are 5: 3；Alternatively, including 6 uplink in radio frames Frame, 2 downlink subframes, i.e., the ratio of uplink subframe to downlink subframe of one radio frames are 6: 2；Alternatively, including 7 uplink in radio frames Frame, 1 downlink subframe, i.e., the ratio of uplink subframe to downlink subframe of one radio frames are 7: 1；Alternatively, including 8 uplink in radio frames Frame, 0 downlink subframe, i.e., the ratio of uplink subframe to downlink subframe of one radio frames are 8: 0.
The attribute of radio frames further includes uplink and downlink other than including the frame length of radio frames, the proportion of ascending-descending subframes No matter wirelessly position of the frame in radio frames still only needs the case where meeting the first HARQ timing length for communication equipment, The ratio of uplink subframe to downlink subframe of frame is how many, and the position of sub-frame of uplink and downlink subframe is not specifically limited.
For example, when radio frames include 2 sub-frame of uplink, when 4 downlink subframes, 2 sub-frame of uplink can be adjacent, It can be spaced 1 subframe, alternatively, 2 subframes can also be spaced, alternatively, 3 subframes can also be spaced, or 4 can also be spaced A subframe.
In another example when 4 downlink subframes, 3 sub-frame of uplink can be continuous when a radio frames include 3 sub-frame of uplink, Can also be adjacent with 2 sub-frame of uplink, alternatively, not phase between any two sub-frame of uplink being also possible in 3 sub-frame of uplink It is adjacent.
It should be noted that n is the frame length of radio frames when the ratio of uplink subframe to downlink subframe of radio frames is 0: n this configuration, At this time due to not having sub-frame of uplink, data just just also are passed without uplink, it therefore, in this case, in a radio frames can be with It does not include sub-frame of uplink.
Similarly, when the ratio of uplink subframe to downlink subframe of radio frames be n: 0 this configuration when, n be radio frames frame length, at this time due to There is no downlink subframe, just just data is passed without downlink, therefore, in this case, under can not including in a radio frames yet Row subframe.
For example, when a radio frames include 8 subframes, the ratio of uplink subframe to downlink subframe of the radio frames can for 8: 0,7: 1, 6: 2,5: 3,4: 4,3: 5,2: 6,1: 7,0: 8, as shown in Figure 2 D.
Wherein, when the ratio of uplink subframe to downlink subframe of radio frames is 0: 8, due to there is no uplink just to pass data, one is wireless It can not include sub-frame of uplink in frame；When the ratio of uplink subframe to downlink subframe of radio frames is 8: 0, due to there is no downlink just to pass data, It therefore, can not include downlink subframe in a radio frames.
In another example when the frame length of radio frames is 4, the ratio of uplink subframe to downlink subframe of radio frames can for 0: 4,3: 1,2: 2, 1∶3、4∶0。
Wherein, when the ratio of uplink subframe to downlink subframe of radio frames is 0: 4, due to there is no uplink just to pass data, one is wireless It can not include sub-frame of uplink in frame；When ratio of uplink subframe to downlink subframe is 4: 0, due to there is no downlink just to pass data, one It can not include downlink subframe in radio frames.
It is that communication equipment provided in an embodiment of the present invention is sent or received data only need to meet a kind of HARQ above The case where timing length；With the demand of business development, different business may have different requirements to delay, and a communication is set It is standby to handle multiple business relevant to two kinds of HARQ timing lengths, for example, when business 1 needs to meet the first HARQ timing Long, business 2 needs to meet the 2nd HARQ timing length, communication equipment in processing business 1, using with the first HARQ timing length If relevant radio frames, the re-transmission timing requirements that can satisfy business 1 are still used when communication equipment is in processing business 2 As soon as if radio frames relevant to HARQ timing length, being unable to satisfy the re-transmission timing requirements of business 2.
Therefore, when communication equipment needs to handle multiple business relevant to two kinds of HARQ timing lengths, in order to avoid needing The defect that the probability of successful retransmission of business to be processed is lower, retransmission efficiency is poor, the embodiment of the present invention is it is further proposed that one kind can The frame length of the radio frames of choosing, specifically:
The frame length of radio frames is equal to the least common multiple of first the second product of sum of products；
First product is equal to the product of the first HARQ timing length and 2；
Second product is equal to the product of the 2nd HARQ timing length and 2.
For example, the first HARQ timing length is 2, the 2nd HARQ timing length is 4, then the first product is 4, and the second product is 8, since 48 least common multiples are 8, then the frame length of radio frames is 8.
In another example the first HARQ timing length is 2, the 2nd HARQ timing length is 3, then the first product is 4, the second product It is 6, since 46 least common multiples are 12, then the frame length of radio frames is 12.
When communication equipment needs to meet two kinds of HARQ timing lengths, not only to meet re-transmission demand when first biography, also want Meet re-transmission demand when retransmitting, for example, if the 0th subframe is sub-frame of uplink, when the first HARQ timing length is 2, second When HARQ timing length is 3, then it is directed to the first HARQ timing length, in order to meet the re-transmission of the 0th subframe, the 4th subframe is needed To be sub-frame of uplink, meanwhile, the 4th subframe in order to meet the re-transmission of the first HARQ timing length and the 2nd HARQ timing length, 8th subframe and the 10th subframe are required to as sub-frame of uplink；Similarly, for the 2nd HARQ timing length, in order to meet the 0th The re-transmission of subframe, the 6th subframe need for sub-frame of uplink, meanwhile, the 6th subframe is in order to meet the first HARQ timing length and The re-transmission of two HARQ timing lengths, the 10th subframe and the 12nd subframe are required to as sub-frame of uplink.
Therefore, in the case where communication equipment needs to meet two kinds of HARQ timing lengths, the ascending-descending subframes of radio frames are matched Than needing to meet following rule:
Ratio of uplink subframe to downlink subframe is related to variation granularity, and it is fixed about the first HARQ that variation granularity is positively correlated with frame length, negative Shi Shichang and the 2nd HARQ timing length；
Variation granularity is specially that the minimum number of increased sub-frame of uplink is once needed when increasing sub-frame of uplink in radio frames Amount.
In the application, need to meet certain interval between any two subframe that variation granularity includes, it so just can be with Realize re-transmission demand, in the embodiment of the present invention, optionally, radio frames are also related to sub-frame interval, and sub-frame interval is to change granularity In the sub-frame of uplink for including in the adjacent sub-frame of uplink of any two between interval, sub-frame interval and frame length and change grain Degree is related.
Wherein, optionally, sub-frame interval meets following rule:
Sub-frame interval=(frame length/variation granularity) -1 (formula one)
Certainly, an above-mentioned specific example for only calculating sub-frame interval, but it's not limited to that, as long as being calculated Sub-frame interval meet re-transmission demand.
Wherein, variation granularity can describe in this way, not increased one by one when such as increasing sub-frame of uplink, Increased as unit of group, in this way, not only meeting the demand for just passing and unsuccessfully being retransmitted, also meets to retransmit for the first time and lose The demand that can be retransmitted again is lost, for example, disposably to increase by 2 sub-frame of uplink, at this point, such as if variation granularity is 2 If fruit needs to increase by 5 sub-frame of uplink, need to increase by 10 sub-frame of uplink, still, before the increased sub-frame of uplink of institute It include if wanting increased sub-frame of uplink below, at this point, actually the number of increased sub-frame of uplink can be less than in total 10,；If variation granularity is 3, disposably to increase by 3 sub-frame of uplink, at this point, if necessary to increase by 4 sub-frame of uplink, Actually increase by 12 sub-frame of uplink, still, before the increased sub-frame of uplink of institute included wanting increased uplink below If frame, at this point, actually the number of increased sub-frame of uplink can be less than 12 in total.
In the embodiment of the present invention, optionally, variation granularity meets following rule:
Wherein, d is variation granularity, and c is frame length, and a is the first HARQ timing length, and b is the 2nd HARQ timing length.
In the embodiment of the present invention, in the case where communication equipment needs two kinds of HARQ timing lengths, if it is determined that go out wireless After the frame length and variation granularity of frame, so that it may determine the proportion of the ascending-descending subframes of radio frames.
For example, the first HARQ timing length is 2, the 2nd HARQ timing length is 4, then the frame length of radio frames is 8, and can be with Calculating variation granularity is 2, at this point, there are several types of situations for the proportion of ascending-descending subframes, as shown in Figure 2 E:
8∶0、6∶2、4∶4、2∶6、0∶8。
That is, when the 2nd HARQ timing length is 4, the frame length of radio frames is 8 when the first HARQ timing length is 2, At this point, the structure of radio frames can be such that
Radio frames include 0 sub-frame of uplink, 8 downlink subframes；Or
Radio frames include 2 sub-frame of uplink, 6 downlink subframes, 3 downlink subframes in interval between 2 sub-frame of uplink, and 6 Downlink subframe is divided into two groups of downlink subframes, and two groups of downlink subframes include 3 downlink subframes, is spaced 1 between two groups of downlink subframes A sub-frame of uplink；Or
Radio frames include 4 sub-frame of uplink, 4 downlink subframes, between any two sub-frame of uplink in 4 sub-frame of uplink It is non-conterminous, it is non-conterminous between any two downlink subframe in 4 downlink subframes；Or
Radio frames include 4 sub-frame of uplink, 4 downlink subframes, and 4 sub-frame of uplink include two groups of sub-frame of uplink, on two groups Row subframe includes 2 sub-frame of uplink, non-conterminous between two groups of sub-frame of uplink, and 4 downlink subframes include two groups of downlink subframes, and two Group downlink subframe includes 2 downlink subframes, non-conterminous between 2 groups of downlink subframes；Or
Radio frames include 6 sub-frame of uplink, 2 downlink subframes, and 6 sub-frame of uplink include two groups of sub-frame of uplink, on two groups Row subframe includes 3 sub-frame of uplink, is spaced 1 downlink subframe between two groups of sub-frame of uplink, 2 downlink subframes are non-conterminous；Or Person
Radio frames include 8 sub-frame of uplink, 0 downlink subframe.
In another example the first HARQ timing length is 2, the 2nd HARQ timing length is 3, then the frame length of radio frames is 12, and It is 6 that variation granularity, which can be calculated, at this point, there are several types of situations for the proportion of ascending-descending subframes, as shown in Figure 2 F:
0∶12、6∶6、12∶0。
That is, when the 2nd HARQ timing length is 3, the frame length of radio frames is when the first HARQ timing length is 2 12, at this point, the form of radio frames can be such that
Radio frames include 0 sub-frame of uplink, 12 downlink subframes；Or
Radio frames include 6 sub-frame of uplink and 6 downlink subframes, any two sub-frame of uplink in 6 sub-frame of uplink it Between it is non-conterminous, it is non-conterminous between the different downlink subframe of any two in 6 downlink subframes；Or
Radio frames include 12 sub-frame of uplink, 0 downlink subframe.
In another example the first HARQ timing length is 3, the 2nd HARQ timing length is 4, then the frame length of radio frames is 24, and It is 12 that variation granularity, which can be calculated, at this point, there are several types of situations for the proportion of ascending-descending subframes, as shown in Figure 2 G:
0∶24、12∶12、24∶0。
Also it just saves your breath words, the first HARQ timing length is 3, and when the 2nd HARQ timing length is 4, the frame length of radio frames is 24；
Radio frames include 0 sub-frame of uplink, 24 downlink subframes；Or
Radio frames include 12 sub-frame of uplink and 12 downlink subframes, any two sub-frame of uplink in 12 sub-frame of uplink Between it is non-conterminous, it is non-conterminous between the different downlink subframe of any two in 12 downlink subframes；Or
