Described repetitive schedule information, indicated by the PDCCH signalings for dispatching the PDSCH channels for carrying SC-MTCH, i.e., it is logical The DCI for crossing G-RNTI scramblings is indicated.
The number information of described packet, refer to each packet is numbered, described numbering is in its value model Enclose interior cycle assignment.
As a kind of implementation, eNB indicates each business datum described in UE by system message or SC-MCCH message The times N of packet scheduling.
As a kind of implementation, to a packet, access network elements continuously dispatch n times packet, i.e., each data Bag successively continuously dispatched n times.
Once scheduling described in this method, including the multiplicating of PDSCH channels and/or PDCCH channels are sent, such as M1 Secondary PDCCH is repeated to send and M2 PDSCH repetition is sent, and forms the once scheduling described in this method, i.e., as shown in Figure 2 is Dynamic dispatching and transmission.
UE receives the SC-MTCH packets that eNB is sent according to each packet repetitive schedule information.
If UE is properly received a packet, the follow-up repetitive schedule of the packet can be ignored.Otherwise, UE mono- is direct The repetitive schedule of the packet is received, until being properly received the packet, or until detecting the scheduling of new packet.
The method that UE judges to be properly received a packet includes one below：
When the numbering of packet the 1st, is included in described repetitive schedule information, if UE has been properly received a business datum The numbering n of bag, then it is assumed that be properly received the packet that package number is n.
2nd, the serial number information of scheduling is included in described repetitive schedule information, and UE has been instructed to the repetition of each packet Scheduling times N, or the repetitive schedule packet contain still remaining scheduling times information, then UE only needs to be successfully received one Any once dispatching in the scheduling of packet n times, then it is assumed that be properly received the packet, i.e., in the continuous 1 scheduling sequence for arriving N Number, or in N to 1 still remaining scheduling times, UE, which only needs to be properly received, wherein once to be dispatched.
Below by way of specific example to illustrate the implementation process of the technical scheme of the embodiment of the present invention：
Access network elements continuously dispatch the business datum n times, then dispatch next SC-MTCH packets.
Access network elements in the PDCCH signalings DCI of business G-RNTI scramblings, refer to when dispatching SC-MTCH packets Show the numbering of the packet of current scheduling, this numbers cycle assignment in its span, such as numbering is 0 to 7, then packet Numbering distributed from 0 to 7, then loopback again be allocated from 0 to 7.UE identifies different data according to the numbering of the packet The scheduling of bag.
As a kind of implementation, access network elements are by SC-MCCH message or system information block instruction in scheduling SC- During MTCH business, the times N of each SC-MTCH business repetitive schedule.
Access network elements are in the described SC-MTCH packets of each scheduling, including continuously transmit M1 PDCCH signaling, With M2 PDSCH channel data.This is formed to a full schedule of the data and transmission.
UE then judges whether to have succeeded according to the package number of the scheduling indicated in the PDCCH signalings DCI received Receive the packet.For example, UE indicated numbers in the DCI received according to bag are n, and UE is n-1 being properly received numbering Packet after, be properly received numbering be n packet, then UE can be neglected the DCI instruction PDSCH scheduling, until UE What is received indicates the DCI that package number is n+1, and it is n+1's that now UE receives numbering according to the instruction of the DCI PDSCH is dispatched.
