Node B sends the method for data on continuous resource, comprising:
Step 1:Node B disposes HS-SCCH according to table 2, and is handed down to subscriber equipment, and here, the number of retransmissions of each transmission block is designated as: ReTrans_times=4;
Step 2:
Method one (the shared time slot of the transmission block that Node B is sent is as shown in Figure 2, and wherein, T1, T2, T3 and T4 represent transmission block 1,2,3,4 respectively):
2.1:Node being subscriber equipment, B selects 4 HARQ processes; Be assumed to be Process1, Process2, Process3 and Process4; And sending 4 transmission blocks respectively according to the order from Process1 to Process4 (promptly sends transmission block 1 with Process1, sends transmission block 2 with Process2, by that analogy); The form that sends shown in information field, after the transmission with metadata cache in the soft buffer memory of HARQ to treat the transmission of back;
2.2: whether the value of judging ReTrans_times is greater than 0.If then Node B is sent in the transmission block of buffer memory in 2.1 again according to the order from Process1 to Process4, and the value of ReTrans_times is subtracted 1, repeating step 2.2; Otherwise, finish.
When adopting this method, the UE side need be selected 4 processes voluntarily, is assumed to be ProcessA, ProcessB, ProcessC and ProcessD, receives the transmission block that sends through Process1, Process2, Process3 and Process4 from Node B respectively.
Because the order of each transmission block has TSN among the MAC-ehs (Transmission SequenceNumber transmission sequence number carry out) indication, so UE only uses when receiving and receives the re-transmission transmission block that identical HARQ receives these data first.
For this method, like Node B a plurality of Transmission Time Intervals are together carried out CRC, after the step 2.1, receive once all transmission blocks of transmission as UE after, carry out following steps:
A1, UE carry out combined decoding to each transmission block and unite and separate CRC, if correctly then this transmission block is sent to the upper strata, no longer receive for follow-up re-transmission; Otherwise, soft bit buffer memory is got up, carry out next step;
A2, UE merge back execution in step A1 with itself and the last transmission block that receives one by one behind all transmission blocks that receive transmission next time.
Method two (the shared time slot of the transmission block that Node B is sent is as shown in Figure 3, and wherein, T1, T2, T3 and T4 represent transmission block 1,2,3,4 respectively):
2.1Node B is the 1st transmission block of continuous 4 transmissions on certain Process, the form of transmission is shown in information field;
2.2NodeB on ensuing authorization resources, send 3 transmission blocks of residue according to 2.1 identical methods.
When UE adopted 4 different Process to receive data, at first UE need distribute 4 processes for this receives, the reception of the corresponding transmission block of each process, and the operation of similar approach 1 is repeated no more here.
Application example 2:
The RV version information can adopt the mode of binding with the number of transmissions also can adopt the mode of the explicit appointment of HS-SCCH.Wherein the binding information of the number of transmissions and RV version is by system message broadcast announcement UE.The binding information of supposing number of retransmissions and RV version is { (11), (26), (33), (42) }.Wherein, (what the first digit in each bracket represented is which time transmission of each transmission block, and second digit is represented the RV version information that current transmission is adopted).Two kinds of RV version specific modes can be distinguished by the different values of RV field among the HS-SCCH, such as: when RV field numerical value was even number, explicit RV specific mode was adopted in expression, the RV version that this moment, the RV version adopted the RV field to represent always; And if when being odd number, what expression was adopted is the mode of binding with the number of transmissions.
Treatment step is following:
Step 1: HS-SCCH is as shown in table 2 according to the data message configuration, and is handed down to subscriber equipment, and here, the number of transmissions of each transmission block is designated as: Trans_times=4;
Step 2:
Method one (the transmission figure of Node B is as shown in Figure 3):
2.1Node being subscriber equipment, B selects 4 HARQ processes; Be assumed to be Process1, Process2, Process3, Process4; And according to sending 4 transmission blocks respectively from the order of ProcessID from 1 to 4, suppose this time to be transmitted as the n time transmission, then the RV version adopts n the RV version that binding information provides; After the transmission with metadata cache in the soft buffer memory of HARQ with treat the back transmission, Trans_times is deducted 1;
If 2.2 Trans_times greater than 0, Node B is sent in the transmission block of buffer memory in 2.1 according to Process1 to the order of Process4 again so, but the RV version confirm according to the number of transmissions, Trans_times is subtracted 1, repeat 2.2 processes; If said repeating transmission number of times is 0, sends so and finish;
And the operation of UE side is with described in the instance 1.
Method two (the transmission pattern of NodeB is as shown in Figure 4):
2.1Node B is the 1st transmission block of continuous 4 completion on certain Process, the RV version adopts the order of (1,6,3,2) successively, and the form of other transmissions is shown in information field;
2.2Node B sends 3 transmission blocks of residue according to 2.1 identical methods on ensuing authorization resources, the RV version adopts the order of (1,6,3,2) successively.
For method 2, in the UE side, can on same Process, order receive, also can utilize 4 different Process to receive.Description among the details reference embodiment 1 of concrete operations.
