The present invention is described in further detail again below by drawings and the specific embodiments.
The present invention provides a kind of transmission method of the data under semi-persistent scheduling mode, and Fig. 1 is that the present invention realizes semi-static
The schematic flow sheet of the transmission method of the data under scheduling mode, as shown in figure 1, the method is comprised the following steps：
Step 101, UE receives the data of the SPS-C-RNTI scramblings received on PDCCH；
Specifically, UE monitors PDCCH, when there is data to reach on PDCCH, UE receives the data, and utilizes SPS-C-
RNTI masks are decoded to data, if it is possible to realize decoding, then it represents that the data of reception are the number of SPS-C-RNTI scramblings
According to.
Step 102, UE judge SPS-C-RNTI scrambling data whether be semi-persistent scheduling transmission activation signaling, if
It is to perform step 103, if not, performing step 104；
Specifically, UE judge SPS-C-RNTI scrambling data whether be semi-persistent scheduling transmission activation signaling, this is
Because while receiving the data of SPS-C-RNTI scramblings on PDCCH, but can not illustrate here it is what semi-persistent scheduling was transmitted
Activation signaling, UE is that the solution mask of the CRC of PDCCH is obtained by the RNTI of itself for the reception of data on PDCCH, right
In the SPS-C-RNTI masks of 16bit, may be considered for the crc error of the PDCCH scrambled without SPS-C-RNTI by UE
The activation signaling of semi-persistent scheduling transmission；Therefore, UE determine receive be SPS-C-RNTI scrambling data after, in addition it is also necessary to check
Whether fixed bit is set to prespecified value in PDCCH, only when fixed bit is all prespecified
During value, UE just thinks that the data of SPS-C-RNTI scramblings are the activation signaling of semi-persistent scheduling transmission, performs step 103；Conversely,
If fixed bit is not all of being prespecified value that UE thinks that the data of SPS-C-RNTI scramblings are not semi-static
The activation signaling of scheduled transmission, performs step 104.
Step 103, UE judges whether to carry out data re-transmission using non adaptive HARQ, if it is, step 105 is performed,
If not, performing step 101；
Specifically, when the activation signaling that the data of SPS-C-RNTI scramblings are transmitted for semi-persistent scheduling, only using non-
When adaptivity HARQ carries out data re-transmission, be possible to new data occur and retransmit the collision between data, therefore, UE is also needed
Judge whether data re-transmission is carried out using non adaptive HARQ in PDCCH, if it is, step 105 is performed, if not, UE
Need to continue to monitor PDCCH, receive the data of SPS-C-RNTI scramblings, perform step 101；Here, according to data when retransmitting
Whether whether feature changes is divided to for two kinds of non-self-adapting and self adaptation HARQ, i.e., changed judgement according to data characteristics
Whether data re-transmission is carried out using non adaptive HARQ in PDCCH, be certainly if data characteristics when retransmitting changes
Adaptability HARQ, is non adaptive HARQ if data characteristics when retransmitting does not change；Wherein, the number of re-transmission
Include the distribution of Resource Block and scheduling mode, the length of transmission block, the duration of transmission etc. according to feature.
Step 104, UE normally sends data using non-semi-persistent scheduling transmission means；Using non-semi-persistent scheduling transmission side
Formula normally sends data and belongs to prior art, repeats no more here.
Step 105, UE sets the cycle timer of new data transmission；
Specifically, when it is determined that carrying out data re-transmission using non adaptive HARQ, being sent out by PDCCH before illustrating eNB
The current schedule information of UE is given, is to indicate UE scheduling modes for semi-persistent scheduling mode, therefore UE preserves current scheduling
Information；UE is also needed to according to the fixed cycle of new data transmission setting cycle timer, and preserves the duration of the fixed cycle, root
The initial point of next new data transmission can be calculated according to the duration of the fixed cycle；The fixed cycle of the new data transmission is network
What side configured on UE in advance；
Compared with existing technical scheme, only need to set a cycle timer for new data transmission herein, without
A cycle retransmission timer is set again, it is not required that the cycle to setting adds skew, it is not necessary to consider in which week
Phase new data produces collision with data are retransmitted.
Step 106, UE judges whether cycle timer is overtime, if it is, step 107 is performed, if not, performing step
108；
Specifically, UE judges whether the cycle timer of the new data transmission for setting is overtime, if cycle timer is overtime,
Step 107 is performed, if cycle timer is not timed-out, step 108 is performed.
Step 107, UE sends new data on original running time-frequency resource；
Specifically, when after the cycle timer time-out of the new data transmission for setting, represent that UE needs to send new data, because
This UE sends new data on original running time-frequency resource.
The duration of the cycle timer frame that subtracts, continuation are judged whether cycle timer is overtime, performs step by step 108, UE
Rapid 106.
Step 109, when the next subframe after new data is sent completely is reached, UE sends and retransmits data；
Specifically, after new data is sent completely, when next subframe is reached, judging currently whether there are re-transmission data needs
Send, need to send if retransmitting data, UE directly transmits re-transmission data.
