Mode 2: transmitting terminal can detect the control information of attached bag data 2 in control channel, if it is the chase mode that the head of attached bag data 2 passes the HARQ transmission means of packet, transmitting terminal can determine that the HARQ transmission means of attached bag data 2 is the Chase mode, in the situation that the HARQ transmission means of attached bag data 2 is the Chase mode, can utilize the bit mapping mode of the planisphere of SPID indication attached bag data 2.
Mode 3: in general, attached bag data retransmission for current transmission, if it is Chase modes that the head that this data retransmission is corresponding passes the HARQ transmission means of data, the HARQ transmission means of this data retransmission is also the Chase mode, same, if it is IR modes that the head that this data retransmission is corresponding passes the HARQ transmission means of data, the HARQ transmission means of this data retransmission is also the IR mode.Like this, transmitting terminal can be by the HARQ transmission means in the control information that detects attached bag data 2, if the HARQ transmission means of attached bag data 2 is the chase mode, the HARQ transmission means that the first biography data of these attached bag data 2 are described is the chase mode, at this moment, transmitting terminal can utilize the bit mapping mode of the planisphere of SPID indication attached bag data 2.
Like this, in the present invention, if SPID takies the m bit in control information, 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 is referred to as AI_SN), to indicate newly arrived attached bag data are new datas, or the data that retransmit.The span of AI_SN is that { 0,1}, it takies 1 bit in control signal.If the AI_SN of newly arrived attached bag data is not identical with the value of the AI_SN of previous attached bag data, represent that newly arrived attached bag data are new datas; Otherwise, if the AI_SN of newly arrived attached bag data is identical with the value of the AI_SN of previous attached bag data, represent that newly arrived attached bag data are the data that retransmit.

| Retransmit | The Chase mode | SPID2 | CRV2 |
| Retransmit | The Chase mode | SPID1 | CRV1 |
| Retransmit | The Chase mode | SPID2 | CRV2 |
As above shown in 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 not identical.Because different SPID values is used to indicate different CRV, therefore, CRV1 and CRV2 represent different CRV.
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 (namely, total re-transmission number of times is 3), can utilize 4 different SPID values to indicate respectively 4 different CRV, as shown in table 3 below.

| 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 | SPID3 | CRV3 |
| Retransmit | The Chase mode | SPID4 | CRV4 |
As above shown in table 3, different from upper table 2 is: SPID1 can be from { 01,10, take out a value in 11}, SPID2, SPID3 and SPID4 can be from { 00,01, respectively take out a value in 10,11}, and the value of SPID1, SPID2, SPID3 and SPID4 is different.Because different SPID values is used to indicate different CRV, therefore, CRV1, CRV2, CRV3 and CRV4 represent different CRV.
