Under the situation of not conflicting, embodiment and the feature among the embodiment among the application can make up mutually.
Method embodiment
According to an aspect of the present invention, provide a kind of indicating means of bit mapping mode, this method is mainly used in the bit mapping mode at the planisphere of the transmitting terminal packet that indication sends under the situation of receiving terminal transmission data to be transmitted bag.
Fig. 3 is the flow chart according to the indicating means of the bit mapping mode of the embodiment of the invention, need to prove, for convenience of description, in Fig. 3, illustrated and described the technical scheme of method embodiment of the present invention, can in computer system, carry out such as a set of computer-executable instructions in the step shown in Fig. 3 with the form of step.Though figure 3 illustrates logical order, in some cases, can carry out step shown or that describe with the order that is different from herein.Mainly may further comprise the steps (step S302 is to step S304) as shown in Figure 3.
Step S302, transmitting terminal utilize the bit mapping mode of the planisphere of the predetermined bit information indication data to be transmitted bag in the control information, that is, and and can be by the Constellation Rearrangement version (CRV) of predetermined bit information indication data to be transmitted bag.
Step S304, above-mentioned predetermined bit information is non-newly-increased bit information in the control information, and this data to be transmitted bag can also can be retransmission data packet may for just passing packet.
In specific implementation process, transmitting terminal is before utilizing above-mentioned predetermined bit information indication bit mapping mode, and transmitting terminal need determine whether to utilize this predetermined bit information indication bit mapping mode, and can determine by following dual mode:
Mode one: transmitting terminal is before the bit mapping mode of the planisphere that utilizes above-mentioned predetermined bit information indication data to be transmitted bag, transmitting terminal need be according to the value of predetermined bit information, determine whether to utilize predetermined bit information to indicate the bit mapping mode of the planisphere of data to be transmitted bag, in addition, transmitting terminal can also utilize the value of this predetermined bit information, determines the HARQ transmission means of data to be transmitted bag.
Mode two: transmitting terminal is before the bit mapping mode of the planisphere that utilizes above-mentioned predetermined bit information indication data to be transmitted bag, transmitting terminal need be according to the value of this predetermined bit information, determine the HARQ transmission means of data to be transmitted bag, and, determine whether to utilize the bit mapping mode of the planisphere of this predetermined bit information indication data to be transmitted bag according to the HARQ transmission means of data to be transmitted bag.
Preferably, can utilize HARQ bag designator (SPID), that is, HARQ bag designator be indicated the bit mapping mode of the planisphere of data to be transmitted bag as above-mentioned predetermined bit information.In the IEEE802.16 system, SPID and HARQ data packet length have defined original position and the length of HARQ bag data in the circular buffer district jointly, like this, can in the circular buffer district, select a segment encode word to generate current HARQ bag, wherein, the span of SPID is { 00,01,10,11}.Chuan Shu SPID value one is decided to be 00 first, and the SPID value when other retransmit then can be chosen arbitrarily or selecting in its scope in certain sequence.That is to say, when repeatedly transmitting, may reuse some SPID values, also can not use some SPID values.Especially, when each time transmission code rate is identical, and the SPID value is followed successively by 00,01, and 10,11 o'clock, the position that each transmission wraps in female sign indicating number was continuous successively.
Be that SPID is that example describes the embodiment of the invention with predetermined bit information below.
In specific implementation process, the child bag data (for example, son bag data 1) for transmission first can determine whether to utilize SPID to indicate the bit mapping mode of the planisphere of son bag data by following dual mode:
Mode 1: transmitting terminal can detect the control information of son bag data 1 in control channel, if the value of the SPID in this control information is non-vanishing, then transmitting terminal can utilize the bit mapping mode of the planisphere of SPID indication bag data 1, and, if the value of SPID is non-vanishing, really the HARQ transmission means of stator pack data 1 is the Chase mode.Further, if the SPID value is 0, then the HARQ transmission means of son bag data 1 is the IR mode.
Mode 2: transmitting terminal can detect the control information of son bag data 1 in control channel, if the value of the SPID in this control information is non-vanishing, then transmitting terminal really the HARQ transmission means of stator pack data 1 be the Chase mode, HARQ transmission means in child bag data 1 is under the situation of Chase mode, can utilize the bit mapping mode of the planisphere of SPID indication bag data 1.
As fruit bag data (for example, son bag data 2) is data retransmission, then can determine whether to utilize SPID indication bit mapping mode by following three kinds of modes:
Mode 1: transmitting terminal can detect the control information of son bag data 2 in control channel, the value of SPID that passes packet as the head of fruit bag data 2 is non-vanishing, then transmitting terminal can utilize the bit mapping mode of the planisphere of SPID indication bag data 2, and, if the value of SPID is non-vanishing, really the HARQ transmission means of stator pack data 2 is the Chase mode.
Mode 2: transmitting terminal can detect the control information of son bag data 2 in control channel, the HARQ transmission means that passes packet as the head of fruit bag data 2 is the chase mode, then transmitting terminal really the HARQ transmission means of stator pack data 2 be the Chase mode, HARQ transmission means in child bag data 2 is under the situation of Chase mode, can utilize the bit mapping mode of the planisphere of SPID indication bag data 2.
Mode 3: in general, child bag data retransmission for current transmission, if it is Chase modes that the head of this data retransmission correspondence passes the HARQ transmission means of data, then the HARQ transmission means of this data retransmission also is the Chase mode, same, if it is IR modes that the head of this data retransmission correspondence passes the HARQ transmission means of data, then the HARQ transmission means of this data retransmission also is the IR mode.Like this, transmitting terminal can be by the HARQ transmission means in the control information that detects son bag data 2, HARQ transmission means as fruit bag data 2 is the chase mode, the HARQ transmission means that the first biography data of these child bag data 2 then are described is the chase mode, at this moment, transmitting terminal can utilize the bit mapping mode of the planisphere of SPID indication bag data 2.
Like this, in the present invention, if SPID takies the m bit in control information, then SPID can be used for representing 2
mIndividual CRV.
In addition, in the IEEE802.16 system, can passing through ARQ identifier nucleotide sequence number (ARQ Identifier Sequence Number abbreviates AI_SN as), to indicate newly arrived son bag data are new datas, still the data that retransmit.The span of AI_SN be 0,1}, it takies 1 bit in control in the signaling.If the value of the AI_SN of the AI_SN of newly arrived son bag data and previous son bag data is inequality, represent that then newly arrived son bag data are new datas; Otherwise,, represent that then newly arrived son bag data are the data that retransmit if the AI_SN of newly arrived son bag data is identical with the value of the AI_SN of previous son bag data.
By technical scheme of the present invention, do not increasing the control signaling (promptly, control information mentioned above) under the situation, predetermined bit information in the use control signaling (for example, SPID) indicate son to wrap the CRV of data, than prior art, the present invention does not need to use extra control signaling to indicate the CRV of son bag data, can reduce the expense of control signaling, and obtain performance gain.
In the IEEE802.16 system, be that SPID is an example below, the present invention is illustrated with predetermined bit information.
Example
In the IEEE802.16 system, the span of SPID be 00,01,10,11}, SPID takies 2 bits in control in the signaling, the span of AI_SN be 0,1}, AI_SN takies 1 bit in the control signaling.
For the child bag data of transmitting first, utilize the value of SPID, can indicate the HARQ transmission means of son bag data by following table 1.That is, for the child bag data of transmitting first, whether the SPID value that can pass through is 0, and the HARQ transmission means of distinguishing son bag data is the IR mode, or the Chase mode.
Table 1
| The child bag data of whether transmitting first | The SPID value | The HARQ transmission means |
| Be | ??00 | The IR mode |
| Be | 01,10, any one value among the 11} | The Chase mode |
On the one hand, under the Chase mode, pass data (for example, data 1) for head, the SPID value of data 1 is not 00, promptly SPID1 can for 01,10, any one among the 11}; For the data retransmission of this data 1 correspondence, the SPID value of data retransmission without limits, promptly SPID2 can for 00,01,10, any one among the 11}.For example, total the number of transmissions of the HARQ of these data 1 is 4 (that is, always retransmitting number of times is 3), then can utilize 2 different SPID values to indicate 2 different CRV respectively, and is as shown in table 2 below.
Table 2
| Be to transmit first or retransmit | The HARQ transmission means | The SPID value | The CoRe version |
| Transmission first | The Chase mode | ??SPID1 | ??CRV1 |
| Retransmit | The Chase mode | ??SPID2 | ??CRV2 |
| Retransmit | The Chase mode | ??SPID1 | ??CRV1 |
| Retransmit | The Chase mode | ??SPID2 | ??CRV2 |
As above shown in the table 2, SPID1 can be from { 01,10,11} selects a value, and SPID2 can be from { 00,01,10,11} selects a value, and the value of SPID1 and SPID2 is inequality.Because different SPID values is used to indicate different CRV, therefore, CRV1 represents different CRV with CRV2.
On the other hand, under the Chase mode, (for example pass data for head, data 1) and the data retransmission of this data 1 correspondence, if total the number of transmissions of the HARQ of these data 1 is 4 (promptly, total re-transmission number of times is 3), then can utilize 4 different SPID values to indicate 4 different CRV respectively, as shown in table 3 below.
Table 3
| Be to transmit first or retransmit | The HARQ transmission means | The SPID value | The CoRe version |
| Transmission first | The Chase mode | ??SPID1 | ??CRV1 |
| Retransmit | The Chase mode | ??SPID2 | ??CRV2 |
| Be to transmit first or retransmit | The HARQ transmission means | The SPID value | The CoRe version |
| Retransmit | The Chase mode | ??SPID3 | ??CRV3 |
| Retransmit | The Chase mode | ??SPID4 | ??CRV4 |
As above shown in the table 3, different with last table 2 is: SPID1 can be from { 01,10, take out a value among the 11}, SPID2, SPID3 and SPID4 can be from { 00,01,10, respectively take out a value among the 11}, and the value of SPID1, SPID2, SPID3 and SPID4 has nothing in common with each other.Because different SPID values is used to indicate different CRV, therefore, CRV1, CRV2, CRV3 and CRV4 represent different CRV.
By this example as can be seen, under the Chase mode, use SPID to indicate the CRV of current son bag data, do not need to increase extra control signaling, like this, just reduced the expense of control signaling, and obtained performance gain.
Need to prove; the form of the total the number of transmissions of HARQ, SPID value and CoRe version all is the concrete data in order to illustrate that the present invention is cited in the above-mentioned example; but be not limited to this; the invention of adopting other data is still within protection scope of the present invention; in addition, for realizing that in the system except that the IEEE802.16 system Fang Ming of this method is also within protection scope of the present invention.
In sum, by means of technique scheme of the present invention, do not increasing the control signaling (promptly, control information mentioned above) under the situation, use the predetermined bit information in the control signaling (for example, SPID) to indicate the CRV of son bag data, than prior art, the present invention does not need to use extra control signaling to indicate the CRV of son bag data, can reduce the expense of control signaling, and obtain performance gain.
The above is the preferred embodiments of the present invention only, is not limited to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
